Continuous forming die for machining corrugated resistance tube support

Abstract

The invention relates to the technical field of resistance tube processing equipment, in particular to a continuous forming die for processing a corrugated resistance tube support, which comprises a lower die set and an upper die set arranged right above the lower die set, the lower die set comprises a lower support plate, a lower foot pad, a lower die holder, a lower back plate, a lower base plate and a lower die plate which are sequentially arranged from bottom to top; the lower die plate is provided with a forging and pressing positioning groove, a punching positioning groove, a cutting positioning groove and a bending pressing groove, a lower die insert core is arranged beside the cutting positioning groove, and discharging holes penetrating through the lower die plate, the lower base plate, the lower back plate and the lower die base are formed in the bottoms of the punching positioning groove and the lower die insert core. The upper die set comprises an upper die base, an upper back plate, an upper base plate, an upper clamping plate, a stopping plate and an upper stripping plate which are sequentially arranged from top to bottom. The upper stripping plate is provided with a stretching bow aligned with the forging and pressing positioning groove, a punching needle aligned with the punching positioning groove, a punch aligned with the lower die insert core and a bending cutter aligned with the bending pressing groove. And the production efficiency is high, the product quality is excellent, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of resistance tube processing equipment, in particular to a continuous molding die for processing corrugated resistance tube brackets. Background technique [0002] Such as figure 1 The shown corrugated resistance tube bracket includes a circular protruding convex hull, which is used to embed the port of the resistance tube for positioning. The convex hull has a plurality of cooling holes, and the bottom of the bracket is bent as a support part. The processing usually requires forging ( Press out the convex hull), punching (punching out the heat dissipation holes), cutting (forming the semi-circular edge of the top, rounded corners of the support part), and bending (forming the support part) are combined to complete the four processes to manufacture a finished bracket However, due to the limitations of mold technology, the existing processing methods of corrugated resistance tube brackets usually need to us...

AI Technical Summary

Problems solved by technology

Finally, switch the stamping die used for bending, and process the bending angle required by the workpiece. A total of four processes are required, and four die changes can be obtained such as figure 1 The corrugated resistance tube support shown seriously affects production efficiency

Moreover, due to multiple mold changes and multiple positioning, it is easy to cause the hole position to be misaligned, and the appearance is unqualified, which also has a great impact on the quality of the product.
