Powder metallurgy structural parts swing bar die design

With the plate fixed in the template, the length of the control Boss 11.2mm,[link widoczny dla zalogowanych], its height slightly larger than the negative mode the height of the compacts can be prolapse cavity. Another floating jacket tube, its base connected two lead core, lead core is equipped with two springs, when pressed under the action of the spring, floating down along the stylet, the template fixed in the next two panels (10, 11) floating on the set position of the spring, two threaded stylet from the guide and to control and adjust the height plus powder coat pipe, jacket size 7.2mm tube console surface. 2 Ma Zhiying: powder metallurgy structural parts of the die design of swing lever 27 * its structure is characterized by: die structure is simple, cutting method using the mold, high precision, the combination forming the inner jacket to the first two table, due to spring force, two-way products are suppressed, the density of step with the part of the uniform. In the design to control the jacket tube and the casing, the high pressure core plate, and their high degree of control the table size of 4mm, see Figure 4 die structure, and their relationship is as follows Type: H1 = H2 h1 +4 where a H-- The jacket pipe height; H, - height within the casing; h - the height of pressure core plate. 2.2.3.3 round two in the core 7, with the plate fixed to the beam is connected with the template, suppress the negative mode with a floating, two- way can be suppressed. With the negative mode when stripping down, strip off from the compacts. Fixed in the core circle template. Its structural features: three holes in the same shape, the mold to control its position, product consistency, and reduce the machining error accumulation when the fixture. 2.3 The working principle of the mold powder by volumetric method 2.3.1 installed equipment powder, adjust the negative mode under the control of the loading cylinder powder capacity. 2.3.2 Forming the punch down into the negative mold ,[link widoczny dla zalogowanych], the casing fixed and jacket pipe in powder and die friction and spring force, floating down to a fixed position, forming compacts, after packing, rushed back to the position on the upper die. 2.3.3 Stripping down under the cylinder with a cavity , while 2 of 7 cylindrical mandrel with a negative mold down, with prolapse compact, ejection seat and not move inside and outside the casing, the product is to sell off the top mode. Cylinder back to the next line, after stripping the compacts was cloudy swelling of the elastic aftereffect model hold up, pushing the cavity to rise to plus powder compacts position, the circular core from the compacts in extrusion, and then compacts light by the operator light into the tin, into the next process after sampling. 2.4 Swing Arm verification process compacts the small batch production through five (per 1000 ~ 2000), in each of the checks, the rough density, dimensional accuracy and geometrical tolerances to achieve the process requirements, see Table 1. In the processing operation of the process , out side off corner of the product less the strength to meet the requirements of rough. Good general description of products, suppression mode structure is reasonable, practical, flexible regulation, in line with requirements. 3.1 Process 3 products work under the swing lever performance and accuracy requirements, the development process as a mixture of a burn to suppress a sintering pressure of a complex machining of a plastic one for a test of a red oil product packaging. 3.2 shows the entire process in this product,[link widoczny dla zalogowanych], from the perspective of forming , pressing is the most critical step process, the structure of the mold is reasonable to suppress a direct impact on forming precision products,[link widoczny dla zalogowanych], of course, equally important processes behind. Pressure and re-shaping of the mold structure and the same principle and mode suppression , but relatively simple, there is no longer voiced. 4 Conclusion (1) After the design of compact two-stage and die, automotive parts powder metallurgy with the swing rod shaped, smooth realization of a molding, to achieve the expected design effect, used to meet the requirements of mass production. (2) powder metallurgy die parts oscillating rod, designed, structured, well-conceived, the successful solution of the two surfaces and the precise location of the problem with three holes to ensure the consistency of the product forming and realization of two-way suppression requirements. (3) five small batch production, a total of more than 5000 sent to the other assembly, of which more than 100 other pieces of random samples for verification and strength testing of process, to product design,[link widoczny dla zalogowanych], mold design and reasonable instructions, floating spring jacket tube forming the table The method can promote the use of two types of powder metallurgy parts in the table. (4) This product from forging documents to powder metallurgy parts, 50% cost savings , materials and significantly reduce energy consumption, has obvious economic benefits.
