Mother-son composite wedge mechanism

Abstract

The invention discloses a mother-son composite wedge mechanism. The mother-son composite wedge mechanism comprises a lower die seat and an upper die seat; the lower die seat is slidably connected witha mother wedge, and the mother wedge is provided with a groove; a driving seat is arranged at the groove bottom of the groove, one side of the driving seat is provided with a flanging fame die, and the other side of the driving seat is provided with a first wedge panel; the first wedge panel is provided with a first inclined surface and a first vertical surface, and the first inclined surface isarranged over the first vertical surface; the end of the mother wedge is provided with a back-off assembly for enabling the mother wedge to back off; the upper die seat is provided with a slide blockseat, the lower portion of one side of the slide block seat is slidably connected with a slide block, and the other side of the slide block seat is provided with a second wedge panel; one side of theslide block is provided with a flanging male die; one side of the second wedge panel is provided with a second inclined surface and a second vertical surface, and the second inclined surface is arranged under the second vertical surface. By designing the mother wedge, the slide block, the back-off assembly and other structures, a back-off mechanism and a flanging mechanism can be integrated, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to a composite wedge mechanism of a mother and a son. Background technique [0002] In order to meet the requirements of strength, function, shape and other aspects of the covering parts, the shapes of the parts are often very complicated. The hole position and shape on the complex shape are often the prerequisites to ensure the smooth installation of the key parts of the car, and the holes and the complex shape on the complex surface have their own particularity. Therefore, how to deal with similar hole positions and shapes is also a key technology in the manufacturing process of automotive stamping parts. The wedge mechanism plays a role in solving the complex size and shape of complex stamping parts in the stamping die. During production and manufacturing, the wedge mechanism is used to realize stamping work at different angles to meet the requirements of different hole po...

Problems solved by technology

[0003] A car cover part is a product with multiple factors. It needs to be turned over, and because of the large angle and large surface difference, it must be turned sideways. Direction removal cannot be applied to automatic lines or even manual lines. This requires that the working insert can be retracted when it is not working, and can be retracted to a position that does not interfere with the product. Therefore, a retraction mechanism and a rollover mechanism are required. The two mechanisms cooperate together, but there is a situation where the internal space is insufficient or the shape of the product part does not allow the addition of a retraction mechanism

In the existing technology, due to the small space in this area, standard wedges or self-made wedge mechanisms are generally used. Debugging is troublesome, the strength is not high, and it is easy to be damaged. It also increases the labor intensity of debugging and maintenance, which is a waste of mold space. Increased tooling development costs
