Heat covers technology and combined-type camshaft treatment

Combined-type camshaft is applied extensively already at heavy truck domain. However, the assembly of a lot of combined-type camshaft craft needs higher suit power normally, the error that exceeds bid appears in avoiding cam fixed position and calibration thereby. To this, the patent technology of EMAG -- heat covers technology, assure axis of camshaft, gear and component of other and accurate combined-type can complete essence has production definitely. The dominant position of combined-type camshaft is well-known: The price lower, weight is lighter, optional with different material process of production, production is more agile also the cam that can use new geometry figure easily, lose radius to wait for example. Stem from the demand that reduces to benzine is used and reduce carbon dioxide to discharge, the use of combined-type camshaft is in future will more general. But, of suit cam and axis replace craft to put in a serious problem: Both cannot high accuracy suit is together, the choice that cannot avoid sequel then grinds working procedure. Below a lot of circumstances, need cam suit to the axis " comfortable model " craft, if press fitting process is medium, roll the requirement of flower, spline or toothed gear. The press fitting power that press fitting process produces may make workpiece is out of shape, bring about cam fixed position and calibration process to appear the error that exceeds bid. Accurate suit heat is covered, contract to be cam suit on the axis through heat namely, can ensure the suit that has do not have obstruction, in order to achieve formulary public errand. The key of this craft is being controlled strictly at wanting " temperature " and " time " wait for craft parameter, and the mechanical design of suit equipment. Already finished constructional camshaft, robot and special clamp technology perfect binding energy implements an error to be less than 15 μ M. the perfect binding energy of robot and special clamp technology implementation error is less than 15 micron. This principle can make camshaft architect more agile when the design, in the production of lot of moderate size that and can ensure can use in workpiece type to change often. The combined-type camshaft of high accuracy decreased to continue greatly the necessity of grinding, if use accurate finished product cam, can not need essence of life completely to grind even. The another advantage of this craft is producing combined-type camshaft at can using different data, include to use what 100Cr6 material pledges to forging wear of cam, essence tastes cam, it is the pulverous metallurgy cam with exact size even, need not have order of grinding work of essence of life again. In addition, if spare parts of form a complete set blocks head and end up also can compare more expensive stuff to make with sexual price. Working procedure is outspread grinding needs after heat covers process when camshaft, heat covers a machine tool to be able to receive a grinder repeatedly, and what the center of VTCDS series grinding of this company lets all these change is very easy: The camshaft with the good treatment robot that heats up a machine tool conveys directly of grinding center lade place of the stuff on the area. The advantage of this kinds of craft also can be used at the treatment to other part. When processing gear rod, can be united in wedlock cheek by jowl to go up to the axis by the gear after grinding, do not need to fear emery wheel is caused operate by accident. In the meantime, also can reduce an axis to grow to the greastest extent, make whole spare parts more compact. Shape through what heat covers camshaft, the combined-type camshaft of high accuracy reduced the need that essence of life grinds greatly, if use cam of accurate finished product, can not need completely even again essence of life is ground. The feature of the technological process of EMAG of the biggest flexibility is to only spare parts of little part machine and workpiece are contacted directly, this made sure the machine can be inside the shortest time (be less than 15 minutes) undertake replacement. The heat that fast suit brings up optimal character to win patent covers worker worker skill general flexibility and productivity are perfect union, and the freedom of the design and shorter to producing technical choice to be able to assure metre. Current when a cam is covered by heat, a cam has been in after warm-up. Deploy a certain quantity of the heat of preheater covers a machine tool to make this technology can apply effectively in producing the job. The above good point that the heat that rolls out just about covers machine tool place to have makes the manufacturing business of a lot of camshaft production business and other and accurate component right heat covers new technology to show great interest, some enterprises are undertaking machining a test, still a few have plant this even brand-new craft throws production. Below good case, the effect that the client provides group of mark of benefit from dust, and seek cover the complete technology that reachs final treatment to heat from prior operation. The component that the compact contact between gear can assure gear axis is compact design and density of tall function sex. Heat covers technical good point: · high accuracy, follow-up craft · does not need to save stuff after heat is covered, the spare parts · that is out of shape · can combine different material does not arise to be able to choose workpiece suit ordinal · to be able to choose angle and axial position · to be able to undertake workpiece is changed quickly freely freely after reducing weight · heat to cover model CNC Milling
