Problems solved by technology

[0002] In the traditional processing technology, for shaft parts with steps, machining technology is generally used, such as: CNC turning, CNC milling, but this kind of technology has low material utilization rate and low production efficiency. For some thin-walled parts , can’t realize processing at all; through continuous improvement, such as Chinese patent (publication number: 101875086A, publication date: 2010.11.03, application number: 201010133112.6) parts cold extrusion molding die, including punch and die, is characterized in that: It also includes a hydraulic mold base and a mold core for back pressure forming; the hydraulic mold base includes upper and lower mold bases, upper and lower pistons mounted thereon, upper and lower backing plates, guide sleeves and guide posts; The upper part of the mold core is connected to the upper backing plate of the hydraulic formwork, and the lower part is connected to the lower backing plate. The punch, die, upper and lower pads constitute the mold core for back pressure molding; the punch is passed through the punch The fixed ring is fixed in the upper mold frame, the bottom of the die is equipped with a ejector rod, and the head of the punch and the bottom of the die combination are arc-shaped; the invention can meet the needs of various static disk back pressure forming, and has good versatility. The mold core is easy to replace and maintain, and has good economic benefits, and because the parts are formed by the mold at one time, the production becomes simple and convenient, the environmental pollution is reduced, the product quality is easy to control, and the cost is significantly reduced; but this technology is not only technically complicated, but also And the installation is not convenient; and a set of molds can only produce one type of product, which greatly wastes the utilization rate of the mold

Embodiment 1

[0025] Describe technical scheme of the present invention in detail below in conjunction with accompanying drawing: a kind of cold extrusion die of parts, as figure 1 , 2 , 3, including upper die base 11, lower die base 4, punch assembly, die assembly, guide post 7, guide sleeve 15 matched with guide post 7, described upper die base 11, lower die base The guide post 7 and the guide sleeve 15 provided between the die base 4 play the role of guiding and positioning; the punch assembly includes a punch 14, a punch fixing plate 13, a punch backing plate 12, and the punch backing plate 12. Die 14 as Figure 4 As shown, the punch 14 is engaged and fixed in the punch fixing plate 13, and the connectors pass through the upper die base 11, the punch backing plate 12, and the punch fixing plate 13 successively, so that the punch fixing plate 1. The punch backing plate is installed and fixed on the upper die base, so that the punch assembly is connected with the upper die base 11; the ...

Embodiment 2

[0031] Compared with embodiment 1, the difference of embodiment 2 is: as Figure 7 Shown, adopt mold of the present invention, change the product of different shape, size that concave mold, convex mold are made, as Figure 8 , 9 Shown punch 14 ", the product 18 " that concave mold 16 " produces is as Figure 10 As shown, the left and right wall thickness 9 of the 18″ product can reach 0.8-1mm, not only can realize the parts manufacturing of thin-walled parts, but also increase the productivity by more than ten times; the material utilization rate can reach more than 80%, thereby reducing the production cost ;Here are only two of the products listed, and other dies and punches can be replaced according to the needs to make other required products, which is convenient, fast and cost-saving;
