Abstract

The unilateral cutting mold relates to a mold for unilaterally cutting the blanked spring leaf when producing the spring leaf. It is mainly designed to solve the problems of low service life and low work efficiency of the current mold for cutting one side of the spring sheet after blanking. It includes a lower mold base, a groove in the middle of the lower mold base, a lower fixing plate in the groove, a positioning groove on the lower fixing plate, a lower knife installed on both sides of the positioning groove, and a pressing block on each side of the lower mold base. The block is fixed on the lower die base by screws and cylindrical pins, the positioning block is mounted on the fixed plate, and a gasket is provided between the pressing block and the positioning block; there is a groove in the lower middle of the upper die base, and the upper fixing plate is installed in the groove, and the upper fixing plate There is also a groove in the middle part of the upper fixed plate, and an upper knife is housed in the groove at the upper fixed plate middle part, and a blade is arranged on both sides of the upper knife. The advantage is that the mold has a long service life and high work efficiency.

Description

A cutting die

Technical field:

The utility model relates to a mold for cutting one side of a blanked spring sheet when producing a spring sheet.

Background technique:

At present, the molds that cut one side of the spring sheet after blanking are all cutting one side of the spring sheet at a time. Since one side of the spring sheet is cut, the lateral force generated during cutting is very large, which will affect the mold. Cause damage, thereby reducing the service life of the mold, and the work efficiency is low. If milling with a milling machine, the work efficiency is even lower, and only 16 pieces can be milled every 8 hours.

Invention content:

The technical problem to be solved by the utility model is to provide a unilateral cutting mold with high working efficiency and long service life for unilateral cutting of spring pieces after blanking.

The above purpose is achieved in this way: it includes a lower mold base, a groove is formed in the middle of the lower mold base, a lower fixing plate is arranged in the groove, a positioning groove is arranged on the lower fixing plate, a lower knife is installed on both sides of the positioning groove, and a lower knife is installed on both sides of the lower mold base. Install a pressing block each, the pressing block is fixed on the lower mold base by screws and cylindrical pins, the positioning block is installed on the fixing plate, and a gasket is provided between the pressing block and the positioning block to adjust the positioning size; the lower middle of the upper die base Groove is arranged, and upper fixed plate is housed in the groove, and the middle part of upper fixed plate also has groove, and upper knife is housed in the groove in the upper fixed plate middle part, and both sides of upper knife have edge.

Usage method and advantages: Fix the lower mold base on the workbench of the mechanical press, and fix the upper mold base on the upper slider of the mechanical press. When working, take two spring pieces after blanking, two pieces The spring pieces are arranged side by side above the lower knife, the mechanical press works, and the upper die base moves downward to complete the shearing operation. The advantage is that because the two springs are cut on one side at the same time, the lateral forces generated when the two springs are cut cancel each other out, and will not cause damage to the mold, so the mold has a long service life and high work efficiency. It can cut more than 1000 pieces of blanked spring leaf.

Fig. 2 is a top view structural schematic diagram of the lower die of the present invention, in which 11 is a workpiece.

Detailed ways:

Referring to Figures 1 and 2, it includes a lower mold base 3, a groove in the middle of the lower mold base, a lower fixing plate 5 in the groove, a positioning groove on the lower fixing plate, a lower knife 8 is installed on both sides of the positioning groove, and the lower mold base A briquetting block 4 is installed on each side, and the briquetting block is fixed on the lower mold base through a screw 9 and a cylindrical pin 10, and the positioning block 6 is installed on the fixing plate 5, and a spacer is provided between the briquetting block and the positioning block for adjusting the positioning size There is groove in the lower middle part of patrix 1, and upper fixed plate 2 is housed in the groove, and the middle part of upper fixed plate also has groove, and upper knife 7 is housed in the groove of upper fixed plate middle part, and edge is arranged on both sides of upper knife.
