Description

A compound mold for one-time molding of two-way folding and side punching

technical field

The invention relates to a one-time forming compound mold for bidirectional folding and side punching.

Background technique

6 is a cross-sectional view of the flat plate 14 before molding, and FIG. 7 is a schematic view of the flat plate after molding. After molding, the flat plate forms a first flange 141, a second flange 143 and a mounting hole 142 close to the second flange 143, Since the position of the mounting hole and the second flanging is close, in actual processing, because the flanging die has almost no space for the punching die after forming the second flanging, it is difficult for the two flanging and the mounting hole to be processed at one time. It is obtained in stamping, and it is completed in two steps by two equipments, which will inevitably lead to the decline of work efficiency and the reduction of processing accuracy. At present, the production workshop does not have a composite mold for forming two-way hemming and side punching at one time.

SUMMARY OF THE INVENTION

In view of the deficiencies in the above problems, the present invention provides a one-time molding of a composite mold for bidirectional hemming and side punching.

In order to achieve the above-mentioned purpose, the present invention provides a one-time molding bidirectional hemming with side punching composite mold, including:

a lower mold, the left side of the lower mold has a trapezoidal surface for forming a plate, and a middle part of the lower mold has a horizontally penetrating through hole;

Flanging die, the flanging die is slidably arranged on the left side of the lower die and is equipped with a first compression spring, the flanging die is machined with a feed hole on the right side and is located under the feed hole The flanging convex part on the side, a punching bottom die is arranged in the feed hole, the flanging convex part matches the shape of the trapezoidal surface, and the flanging die also processes a third inclined surface on the left side;

The knife feed movable seat is slidably arranged on the right side of the lower die and is equipped with a second compression spring, the left side of the knife feed movable seat is equipped with a punching die, and the knife feed movable seat is provided with a second pressure spring. The fourth slope is processed on the right side of the seat;

Upper die, the upper die is located above the lower die, the lower surface of the upper die is provided with a first wedge, a flanging knife, a gas spring, and a second wedge from left to right, and the first wedge It is located on the upper part of the flanging die, the lower end of the first wedge is machined with a first inclined surface, the flanging knife is located on the left side of the trapezoidal surface, the lower part of the gas spring is provided with a pressure block, and the second The wedge is located above the movable feed seat, and the lower end of the second wedge is machined with a second slope;

The device arranges the punching die and the flanging die on both sides of the lower die, and sets the feed hole on the flanging die, which finds a space for the feeding of the punching die, and realizes two flanging and Side punched.

Preferably, there are four gas springs, corresponding to the positions of the end corners of the lower die;

In the above technical solution, the action of the four gas springs makes the force of the pressing block on the plate more uniform, and the positioning of the plate is more stable.

Preferably, a waste hole is also processed on the flanging die, the lower diameter of the waste hole is large, and the upper end of the waste hole is communicated with the feed hole;

In the above technical solution, the waste hole is convenient for the punching waste to automatically leave the feed hole, which is convenient for the next punching.

Preferably, in the initial state, the flanging die slides to the leftmost position under the action of the first compression spring;

In the above technical solution, the flanging die is located on the left side, which is the space for the first flanging of the panel.

The beneficial effects of the present invention relative to the prior art are: because the position of the installation hole is close to the second flanging, the flanging die cannot avoid the space after forming, and the feeding of the punching die is difficult. The side die is arranged on both sides of the lower die, and the feed hole is set on the flanging die, which finds space for the feed of the punching die, and realizes two flanging and side punching in one compound die.
