Description

Reverse flanging wedge mechanism

technical field

The utility model relates to a reverse flanging wedge mechanism.

Background technique

For large automotive panels with trimming, punching and flanging, the mold structure has certain restrictions. Generally, when flanging downwards, you can compound the process contents such as punching, but when flanging upwards, it can only be divided into two processes, because according to the previous structure, the lower mold needs to float upwards. Once the lower mold floats, there will be a floating gap. There will be a relative displacement of the mold, even if it is 0.05 mm, it will affect the function and life of the mold, and increase the cost of the mold and the production cost of the plate.

Utility model content

The technical problem to be solved by the utility model is to provide a reverse flanging wedge mechanism, which can realize the up and down reverse wedge movement function.

In order to solve the above problems, the specific technical scheme of the utility model is as follows: a reverse flanging wedge mechanism, the upper end surface of the horizontal block is slidably connected with an upper driver and a vertical block, and the upper end face of the vertical block is provided with a flanging shaping punch, the convex An upper module is arranged on the upper end of the mold, a return spring is arranged on one side of the horizontal block, and a nitrogen cylinder is arranged on one side of the upper module.

Preferably, the horizontal tackle is polygonal, the surface in contact with the upper driver and the vertical tackle is an inclined plane, and the extension lines of the two inclined planes intersect at one point.

Preferably, the contact surface between the upper driver and the vertical block and the horizontal block is a slope, and the slope of the slope corresponds to the slope of the horizontal block.

Preferably, the flange shaping punch is L-shaped.

The beneficial effects brought by the utility model are as follows: 1. The utility model adopts three inclined planes to interact to realize direction conversion, and has a simple structure and low production cost.

2. When the utility model solves the situation of upward flanging, plastic trimming and punching at the same time, the upper driver drives the horizontal block to move horizontally, and then the horizontal block drives the vertical block to move vertically upwards, so that the vertical block is installed. The shaping punch is closed with the upper mold seat or the upper module installed by the presser to realize the flanging and shaping action. After the molding is completed, the slider of the press moves upwards, the upper mold is opened, the upper driver is opened with the upper mold base, the horizontal block is driven by the return spring to reset, and the vertical block is driven by the nitrogen cylinder installed on the upper die to realize the reset movement and material return.

3. The utility model can be adapted to multiple combined situations of upward flanging, shaping and punching, and can be widely used in the field of mold manufacturing.

detailed description

As shown in Figure 1, a reverse flanging wedge mechanism, the upper end of the horizontal block is slidably connected with the upper driver and the vertical block, the upper end of the vertical block is provided with a flanging shaping punch, and the upper end of the punch is provided with an upper module, A return spring is provided on one side of the horizontal block, and a nitrogen cylinder is provided on one side of the upper module.

Preferably, the horizontal block is polygonal, the surface in contact with the upper driver and the vertical block is a slope, and the extension lines of the two slopes intersect at one point.

Preferably, the contact surface between the upper driver and the vertical block and the horizontal block is a slope, and the slope of the slope corresponds to the slope of the horizontal block.

Preferably, the flange shaping punch is L-shaped.

Before the mold is closed, the upper driver 1 moves downward with the press slider, contacts with the inclined guide plate of the horizontal block 2, and drives the horizontal block 2 to move horizontally. The horizontal block 2 contacts the vertical block 3 with an inclined guide plate to push it to move upward; when the mold is closed, the flanging shaping punch 4 contacts the upper module 5 to complete the molding. After the workpiece is pressed, the mold is opened, and the upper driver moves upward with the press slider to cancel the working pressure. At this time, the horizontal block 2 is reset by its built-in rectangular return spring, and the vertical block 3 also loses the working pressure at the same time. The reset movement is carried out by the upper nitrogen cylinder and its own weight to realize the demoulding of the part, which can be taken out directly.

The above are only preferred embodiments of the present utility model. It should be pointed out that those skilled in the art can make some modifications and improvements without departing from the principle of the utility model, which should also be considered as belonging to the protection scope of the utility model.
