Description

Bending die for convex bag

Technical Field

The utility model relates to a novel mode's beating convex package bending die especially relates to the chain attaches convex package bending die of board.

Background

Convex hull beating and bending are finished in two procedures and are processed one at a time, so that the production efficiency is low, the operation mode is dangerous, and the product precision is low.

This technique has the following problems:

1. the production efficiency is low, two processes are needed for convex hull beating and bending, two sets of dies are needed, the time for die debugging is long during production, and the number of processes is large.

2. The machining precision is low, and due to the fact that machining is conducted on the two sets of dies, machined parts need to be located for multiple times, and machining errors caused by inaccurate positioning can be caused.

3. The danger coefficient is large, and each procedure has certain danger due to the two-step procedure processing.

Disclosure of Invention

In order to solve the problem that production efficiency is low among the prior art, the machining precision is low, the danger coefficient is big, the utility model provides a mould of bending of beating convex bag.

A convex bag bending die comprises an upper die and a lower die which are matched with each other; the upper die comprises an upper die handle 22, an upper die base 1, an upper backing plate 2, an upper fixing plate 3, an upper stripper backing plate 4 and an upper stripper plate 5 from top to bottom; the upper die holder 1, the upper backing plate 2 and the fixing plate 3 are fixed through an upper die fixing bolt 20; the lower die consists of a lower die base 9, a lower backing plate 8, a lower fixing plate 7 and a lower discharging plate 6 from bottom to top; the lower die base 9, the lower backing plate 8 and the lower fixing plate 7 are fixed through a lower die fixing bolt 10; the upper die holder 1 is fixed on a slide block plate of a press machine through an upper die handle 22, and the lower die holder 9 is arranged on a workbench of the press machine and is positioned through a lower die guide post 12 and an upper die guide post 11; the product is fixed by the positioning column 16 and is placed between the upper discharging plate 5 and the lower discharging plate 6.

The upper die handle 22 is fixedly connected with the upper die holder 1 through an inner hexagonal screw 23.

The upper stripper plate backing plate 4 and the upper stripper plate 5 are fixedly connected through hexagon socket head cap screws 18.

The lower discharging plate, the lower fixing plate, the lower template and the lower die base are fixedly connected through the equal-height screws 17.

The lower die holder 9, the lower backing plate 8 and the other end of the lower fixing plate 7 are fixedly connected through an inner hexagonal screw 27.

A spring 14 is arranged between the lower discharging plate and the lower fixing plate.

The lower fixing plate is provided with a convex hull punch 15, and the upper stripper plate backing plate is provided with a convex hull insert 21 at a position corresponding to the convex hull punch.

The lower fixing plate is provided with a bending insert 13, and the upper backing plate is provided with a bending punch 24 corresponding to the bending insert.

A spring 19 is arranged between the upper fixing plate and the upper stripper plate backing plate.

And fixing pins are arranged among the upper die base, the upper padding plate and the upper fixing plate to realize positioning.

And the equal-height screws 25 are also arranged among the upper backing plate 2, the upper fixing plate 3, the upper stripper plate backing plate 4 and the upper stripper plate 5.

The product is bent by one-step punching through a bending punch 24 fixed in the middle of the upper fixing plate 3. The convex hull of the product is formed in one step by punching through a convex hull punch 15 fixed in the middle of the lower fixing plate 7. The above two actions are completed simultaneously. By using the convex bag bending die, one process can be reduced and the product quantity can be increased on the original basis, and the production efficiency is improved by more than 300%.

The utility model has the advantages that:

1. through mould structure optimization, improve production efficiency. The original one-die one-hole is increased to the one-die two-hole, the convex hull punching and bending are combined into one process by the original two processes, one set of die can be completed, and the turnover time and the die debugging time between the processes are saved.

2. And the machining precision is improved. The two molds are combined into a set of mold, and the one-time clamping and positioning can be completed. The newly designed forming and positioning device is of an integrated structure, the relative distance between the two groups of forming devices is fixed, and the positioning error caused by multiple times of clamping and positioning is reduced.

3. The safety of the operation is improved.
