Oblique punching mechanism of stamping die

Abstract

The invention discloses an oblique punching mechanism for a stamping die. The punching mechanism comprises an upper die and a lower die. The upper die comprises an upper die base, an upper pad, an upper clamping plate, a backing plate and a stripping plate which are sequentially connected from top to bottom. The bottom of the upper die base is symmetrically provided with two guide slide plate, a check block is arranged between each guide slide plate and the upper pad, and a sliding block is in sliding connection with each guide slide plate. First return springs are connected between the sliding blocks and the check blocks in the abutting mode. A first inclined surface is arranged on the outer side of the bottom of each sliding block, and a diagonal punch is arranged on the inner side of the bottom of each sliding block. The lower die comprises a lower support plate, a bottom block and a lower die base which are sequentially connected from bottom to top. The top of the lower die base isprovided with a lower template and two driving wedges, and the lower template is provided with a lower die edge insert core of a punching hole matched with the diagonal punch, and the two driving wedges correspond to the two sliding blocks in one-to-one correspondence mode. Each driving wedge is provided with a second inclined surface matched with a first inclined surface on the corresponding sliding block. The oblique punching mechanism for the stamping die can effectively punch the inclined surface of a product.

Description

technical field [0001] The invention relates to an oblique punching mechanism of a stamping die. Background technique [0002] Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called cold stamping die (commonly known as cold stamping die). Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. With the continuous development of the economy and the continuous improvement of the technical level, the structure of the product is becoming more and more diverse, and with the diversification of the product structure, the mold structure is becoming more and more complex and diverse. The processed products often have inclined surfaces, and holes need to be drilled on the inclined surfaces. For this kind of inclined plane punch...

Problems solved by technology

For this kind of inclined plane punching products, it is necessary to rotate the base plane of the product by an angle so that the original inclined plane is rotated into a horizontal plane, and then use the horizontal plane as the punching surface for punching. However, this processing method has the following defects, and it is difficult to accurately position the product. Increased product instability and low production efficiency; in addition, increased mold development costs and maintenance costs are not conducive to saving production costs
