Rope of diamond a string of beads curiums in stone material processes medium application

Summary: Introduced what rope of diamond a string of beads occupies to form reach production method, studied rope of diamond a string of beads curiums the mechanism that processes stone material and process reach his to expect in stone material barren exploitation applies mediumly. Crux word: Diamond rope applies 1 preface of 　 according to stone material in recent years, rope of diamond a string of beads curiums plan time weak point, cut with its agile, low noise, low dust, low pollution, energy-saving wait for a characteristic, wide application received in stone lumber industry. What itself of rope of a string of beads combined diamond to exceed strong tigidity and rope is flexible, make its can get used to exploitation of material of such as waste, this kind curiums distinctly cut pattern, other diamond tool can not be achieved; Additional, rope of a string of beads on length accept restriction scarcely, make its applicability is strengthened, demolish in what a few special situations are like underwater treatment, building etc will produce distinct effect. To promote the development of industry of lumber of our country stone, the author reachs a few use experience to undertake discussion to the application of rope of diamond a string of beads, treatment company is drawn lessons from and consult in order to lay stone capable person. Rope of 2 diamond a string of beads curiums form with production 　 2.

The makes string of a string of beads structure that rope of 1 diamond a string of beads curiums is shown 1 times like the graph. In a many wear in proportion above wire rope set have grain of a certain quantity of diamond a string of beads, between photograph adjacent a string of beads by remove the segregation that supports fixed action to cover space (similar necklace) . The corresponding and mechanical equipment that rope of diamond a string of beads curiums treatment is by the diamond a string of beads that participates in cut to use directly rope and rope of drive a string of beads move (namely the rope curiums machine) finish jointly, before treatment, use copper to cover the butt joint of the head and the tail of string of a string of beads that waits for a butt joint to cover will certain length, form close circle. When treatment, zhang Jin curiums in the rope the rope of closed circuit a string of beads on group of machine guide pulley, in driving force drive ropes of next a string of beads to make high speed motion, the grinding motion that passes a string of beads implements cut. 2.

The 　 of 　 of the craft that make of rope of 2 diamond a string of beads (1) diamond a string of beads is invented from rope of diamond a string of beads now, the improvement that makes technology to a string of beads never has stopped. At present workmanship of diamond a string of beads still is with eletroplating law and law of hot pressing agglomeration are given priority to, and latter takes dominant place. Although Taiwan has a scholar to use method of drill rod solder to make a string of beads of diamond of solder giving drill steel successfully, but have not realize large-scale project to apply at present. The graph uses the sample of diamond a string of beads of preparation of these 3 kinds of craft to part. Agglomeration a string of beads has taller wearability. Through adjusting carcass in scale of each metal component or it is OK to choose abrasive of diamond of different official rank in feudal times, granuality, pH indicator speed of implementation carcass wear and tear and diamond abrasive wear away the adjusting control of speed, make an a string of beads that has different height giving blade and space thereby, in order to get used to the cut with different qualitative capable person. Compare with photograph of a string of beads of hot pressing agglomeration, plating diamond a string of beads makes report craft is relatively simple, and more be helpful for small diameter of a string of beads changing. Because diamond film is thinner, carcass wearability is poorer, metal of its plating Fu is finite to the hold of bead of King Kong stone mill, bead of King Kong stone mill is easy fall off ahead of schedule, overall performance is inferior to reason agglomeration a string of beads, do not suit cut granite, basically wait for the cut with softer qualitative material with Yudalishi at present. (2) keeps apart apply mechanically of the segregation that cover 　 to be apart from segregation and a string of beads of stationary phase adjacent at deciding. At present the commonly used segregation in the project is covered have 3 kinds. Bedspring gasket type is the segregation that uses the earliest covers a form. It is very easy that because segregation of bedspring gasket type is covered,bit is worried when treatment be entered from the clearance between a string of beads, bedspring, gasket and curium in the rope curve athletic action to fall to undertake abrasion to wire rope, cause rope of a string of beads to break stringy invalidation thereby. Contain quartz in treatment especially when the granite with higher component, as a result of quartz hardness is tall, quite serious to wire rope abrasion, because this keeps apart a cut that applies to softer material to pledge this kind. Use lesser already at present. To get used to the need of qualitative cut of tall hardness material, developed to note model type and segregation of the type that note glue to cover. Noting the segregation of the model, type that note glue to cover is with wear-resisting the segregation between appropriative a string of beads fills up plastic, balata. Between a string of beads and wire rope be filled up completely by place of plastic, balata, avoided to grind bits to enter a string of beads and wire rope thereby and abrasion wire rope. Be it appear, make the applied limits that rope of a string of beads curiums extends granite kind the cut treatment of tall hardness material. Among them, application of the type that note model is the widest, and the rope of a string of beads that notes balata in order to press to be covered for segregation curiums basically use at centigrade zero the stone material mining area of the following, colder region, because the microtherm function of balata is compared,this is plastic good, still can retain better flexibility and strength below microtherm, do not send fragile crack. (3) wire rope 　 because a string of beads is to be apart from surely secure what go up in wire rope and drive cut of be issued to lower levels in its, reason wire rope can regard a string of beads as the rope " backbone fine grain " . Rope of a string of beads curiums in using a process, regular meeting of wire rope classics wears away because of exhaustion, the abrasion that worry bit, chemistry is corroded wait for a reason and appear stringy phenomenon, when should machining an area to reach certain amount especially, the phenomenon that break a string is more frequent. Break a rope to affect production not only, and still bring swing the insecure hidden trouble such as bead injury person, because the property of this wire rope is right,rope of a string of beads is used crucial. Besides function of steel wire itself, the life of wire rope is returned with treatment in the process tighten tensile, each guide pulley beforehand the element such as the axial load of the smallest curvature, a string of beads in machining a process and concussion load is concerned, reason should choose professional wire rope to produce the product of the enterprise, and the relevant specification that referenced wire rope answers when using. 3 ropes curium the common procedure 　 that processes stone material works actually in, curium with place of rope of a string of beads cut stone timber is varied, curium cut condition has very big different, in mine treatment of material of stone of exploitation, abnormity and building are demolished etc in using, its curium cut a process to undertake analogy very hard, the article curiums with respect to rope of a string of beads only cut common be out of practice to expect this one model machines a process to analyse rope of a string of beads to curium curium the change that cuts a curve is mixed when the material that cut stone concerned rule. 3.

1 make the same score mechanism of cut of rope of 　 a string of beads and process dispute by pointed hasten Chang Fu is miscellaneous, explain to go to the lavatory, make following assuming to rope of a string of beads: In its radial respect is complete softness, do not assume any curving namely stress; Complete tigidity is finished in axes direction, cannot have any drawing is out of shape. Below this one condition, rope of a string of beads curiums at first the surface that cuts curve and material of stone be curiuminged to just expect is complete coincide, if pursue the first 2 medium curves, include AB, BC, CD3 part line segment is comprised. Right now AB, BC, the interior of CD is worth incline to as a result of radius R at infinity, be sufferred curium shearing force is 0, wear away speed is 0. Curium be in only on cogent border A, b, c, d4 the dot undertakes, make the pointed blade on 4 horn very fast be ground to make the same score, expand to photograph adjacent part, finally, arc AB, BC, CD becomes a flowing curve, if pursue 2 medium curves 2. This one process can be called " make the same score by pointed hasten " . 3.

2 by smooth hasten circle rope of 　 a string of beads processes stone material, its curium the change that cuts a curve basically is by the process of square hasten circle. In the curve 2 in, although pointed horn is ground to make the same score, but whole curium the curvature radius that cuts a curve differs very big still, former the position of 4 horn and around, r value is compared elsewhere small much, its curium cut rate far will fast at other place, make the curvature radius of these place increases stage by stage then, and the partial R that is far from these place is worth corresponding decrescent, the curvature radius of departmental cent mixes until is whole wear curve wear away speed is reached some kind is balanced, if pursue 2 medium curves 3. At this moment the shape of arc of topmost and approximate Yu Yuan of wear curve, friend call this one process " by smooth hasten circle " . This one process curiums in what stone material just expects hit the point may want to spend very long time, what because curium,cut initiative condition is different, cannot form a curve possibly also 3 in that way steady state. Curium in this in cutting a course, a, the curvature 2 o'clock reduces B ceaselessly, decrease finally stop for 0 curvature to curium cut, at this moment arc AB, arc DC and do not attend curium cut loose margin, strict limit comprises two linear. In B, two place of C, bigger curium cut speed to make its curvature radius increases ceaselessly, arc BC curiums cut rate gradually hasten is balanced, adjacent finally at hemicycle, and line AB, DC becomes the tangent of arc BC, point of tangency is B respectively, c. Curiuming cut a curve by smooth hasten in round process, the part of the centre of a circle of its place correspondence is smaller and smaller, by be more than at first 1800 drop stage by stage, should curium the flank AB that cuts a curve, DC paragraph curium cut speed to slow gradually and become finally linear and stop to curium cut, horn of its corresponding the centre of a circle is 180 ℃ . Right now of rope of a string of beads curium actually the share of circular arc BC that cuts a curve to be confined to point of tangency to go up, curium the actual length that cuts a curve shortens significantly. 3.

3 stability curium the curve that cut 　 3 it is a kind of very interesting stability curiums cut position, it carries termination on the head to be bordering on semicircle arc, and in B, the tangent 2 o'clock and loose edge, strict limit synthesizes C again linear, these two linear distances agree with the diametical D of driving pulley right now, whole system is in fore-and-aft (namely AD direction) on stopped to curium cut, in the horizontal stroke up, each bits curium cut rate equal, maintained thereby curium the stability that cuts curvilinear figure. Curium in rope of a string of beads in the whole process of the material that cut stone, curium the figure that cuts a curve is in in most phase adjust change in, the different and ceaseless attune that curiums the interior that cuts a curve cuts rate because of curiuming moves its curvature, and the change of attrib border condition cuts a curve to having an effect to curiuming again, in the curve only 3 this one circumstance falls, a variety of elements achieved a balance and maintained the stability of appearance. Rope of a string of beads curiums the topmost figure that cuts a curve is close to Yu Yuan form, the tension of string of a string of beads that because of curiuming shearing force place causes is by the side of the pine small and tightening an edge big, of tension different, certainly will brings about rope of a string of beads to be opposite of stone pressure different, of the strict limit that approachs muscularity curium cut margin of speed fast Yu Song, make its curvature farther decrease and be less than circular arc slightly; To it contrary, the curvature of loose edge will be more than circular arc slightly. Keep whole with this curium the balance that cuts a curve. In the meantime, tighten the edge accretion as a result of tension, curve reach, make C of point of tangency more approach D point, and the case that B orders is opposite, make the length of AB line segment is more than DC0 stability to curium cut level to curium those who cut a curve is actual curium the length that cuts a curve and appearance keep changeless, consequently the curve gets strength condition stability, need not the parameter such as the initiative tension of regulating system, be a kind relatively ideal curium cut position. 3.

4 remains curium the stability that cut 　 curiums those who cut hind paragraph, b of point of tangency, c gradually to brim A, d is stood by, when should tightening dot of the C on the edge to nod coincide with D above all, margin requirement of the curve will produce a change, curve the balance of 3 is broken, curium cut person remains to curium cut level. In this one phase, curium the corner of the centre of a circle that cuts curvilinear place correspondence from before 1800 decrease continuously, curium the length that cuts a curve is shortened quickly, the pressure of rope of a string of beads on unit length increases, must adjust initiative tension of the system in time, lest a string of beads or diamond are destroyed because of too great pressure. 4 ropes curium cut is used at 　 of 　 of exploitation of material of stone material waste 4.

The prepares rope of 　 diamond a string of beads use before material of waste of 1 stone material extracts, need certain requirement, extract in strip mine commonly, must have power source, fountainhead and highway, have a heavy equipment, carriage tool, greater place at the same time, ledge ply has 500mm and more complete appearance to wait for a condition at least. Use rope of diamond a string of beads to extract stone material wants to pass a series of preparation works. (Stiletto of 1) stiletto 　 is a crucial preparative work, if aperture is hit bad, affect the break-through of rope of a string of beads directly, affect stringy service life and cut efficiency, so stiletto this one working procedure is particularly important. Desire cut it is material of one chunk waste, good to must be hit 3 aperture, namely an upend aperture and two levels aperture. 3 aperture intersect (the 3) that be like a graph, this is optimal makes a way, if 3 aperture are not handed in at a bit, can appear so the following circumstance: A.

The perforation of rope of diamond a string of beads is more troublesome, cannot wear even, so be about new stiletto, reduced manufacturing efficiency so. B.

Although break-through, the meeting when cut is influential to the life of rope of a string of beads, because the rope is in aperture,bend meandering course through turning for many times, to the rope wear away more advantages and disadvantages, lowered the service life of rope of a string of beads so, because this stiletto needs fibrous root occupies actual condition, undertake by operating rules. (2) wears a rope to cross aperture 　 when at present industry of domestic stone lumber uses rope of a string of beads, collect labour of choose and employ persons to wear stringy law mostly, namely: Secure stringy one aspect of the matter many loop flexible cord, wear from one aperture into, use iron wire to be brought from another aperture, such with respect to break-through Shen Zhu rope. (After 3) installs break-through of rope of equipment 　 a string of beads, undertake equipment is installed, because equipment is heavier, plus cut after one plane, need readjust facility, must deploy to have heavy facility beside its consequently, can rise to undertake installing again at any time. (When material of stone of cut of 　 of 4) water supply, the line as a result of the rope fast big, as big as the attrition between stone material, if be not added water or add water insufficient, rope and stone produce much heat between material, not only can make bedspring and wire rope are out of shape, make bedspring possibly even fused and felt is together, lose flexibility, such, can lower the service life of rope of a string of beads. To ensure stringy quality is mixed life, must water supply, water supply must add a person along athletic way of the rope. 4.

The cut 　 that barren of 2 stone material expects uses marble of cut of rope of a string of beads when barren expects, must first cut horizontal, next again cut upend face, such ability assure the success of cut. Cut means is commonly first cut horizontal, hind cut upend face. If first cut upend face, again cut horizontal, when waiting for horizontal cut to want to end, be produced suddenly by the stone material of cut crackle, pin rope of a string of beads, cannot cut, electric machinery idling, and rope of a string of beads happens be out of shape. Rope of a string of beads uses exploitation waste material not only, and still can machine circular arc of all sorts of norms stone material, abnormity, cornerstone to wait, equipment rope curiums machines and tools has tall line fast, type of efficient, high accuracy, curve, arc type, straight formula, be controlled of personal computer and profile modeling two kinds. 5 last word 　 are current, rope of diamond a string of beads is used extensively already gradually in industry of lumber of our country stone, home made rocky material introduce advanced technique and equipment, rope of applied diamond a string of beads will pick stone material and the board that process all sorts of form (basically be abnormity plank) , it has production efficiency is tall, product quality is good, cost is low advantage, reflected modern industry to produce new development of the technology, to obtaining the waste material of high quality and the plank of all sorts of appearance, efficiency of the treatment quality that improved stone ability, production and economic benefits have important sense. As much rope side by side the success application of cut technology, it curiums to traditional frame plank cut means launchs immediate challenge, make those who exceed large board large or efficient, low cost cut becomes reality. Make people more and more the advantage that realises rope of a string of beads to go up in stone material treatment. CNC Milling
