The drawing of method of processing of plasticity of taper aperture mould shapes

Drawing shapes is to show treatment material passes the mould that contains certain taper aperture to reduce the method of processing of a kind of plasticity of its cut area, shape through drawing can form the profile with all sorts of sectional geometry, it is preparation wire and the important means that provide material. The characteristic that drawing machines is: The grain that is helpful for a metal is refined, improve the integral performance of the product, use tool and equipment are simple, and safeguard convenient, in addition, drawing shapes can acquire high accuracy and fast face quality, and did not waste material, be a kind managing model processing technique. The last few years, many scholars machined craft to undertake improvement to traditional drawing, developed a lot of new drawing to machine craft. Specific have the following: 1, turn over tensional drawing it is be opposite in drawplate back end when drawing preform machines a method tensily with returning way, this kind of method reduced drawing mould greatly wear away, decreased to pull wire rod at the same time or profile is pulled phenomenon. 2, drawing of roller type model it is a drawing and the manufacturing technology that rolling combines together, replace traditional Kong Mo with pass roller namely, turned major sliding friction into rolling friction, great reduced attrition resistance, can realize high speed drawing, this technology basically applies in the different of complex interface steel tube to shape. 3, compulsive lubricant drawing it is the pressure boost conduit that installs a slightness in drawplate front or pressure boost model, what the have the aid of when drawing gets preform and vulcanization additive at moving is agglutinant, the additive of will tall viscosity takes drawplate, force additive to enter modular hole, a lubricating film is formed between preform and drawplate, produce fluid motivation result thereby, reduced the effect of attrition. 4, without modular drawing it is one kind does not use traditional drawing pattern, and what support metal is out of shape the quality that fights force to change along with temperature comes true is flexible plasticity processing technique, it is the heats to undertake machining with cooling control method that uses cold heat source. It solved the drawing in traditional drawing Daociduo, deflection efficiency of small, production is low problem, but the uniformity of finished product is poorer, product quality is not stable at the same time. 5, other the ultrasonic vibration drawing that if be in,ultrasonic vibration brings to bear on on drawing model, exceed plasticity drawing to wait a moment.
