Description

Lateral punching structure

【Technical field】

The invention relates to a stamping die structure, in particular to a lateral punching structure.

【Background technique】

For products that require punching on the side after right-angle forming on the stamping part, please refer to Figure 1, which shows a schematic diagram of a product that requires side punching. Usually, it is necessary to punch sideways on the punching part on the side of the product 1, and then form the side punching hole 2. The mechanism for completing the lateral stamping process is mainly realized by driving the insert to move laterally by the drive block. In the existing side punching of stamping parts, two driving blocks are used in the side punching part to drive the insert to move laterally to press the product, so as to prevent the deformation of the side punching product.

Please refer to FIG. 2 , which shows a schematic diagram of a conventional lateral punching structure. The existing lateral punching structure includes: the first drive block 10, the second drive block 11, the side push block 20, the small splint 21, the small stripping plate 22, the punch 23, and the knife-edge insert 30. The existing lateral In the punching structure, under the action of the second driving block 11, the knife-edge insert 30 first contacts the product 1 before the mold is closed. Because there will not be a large inner hole in the general stamping part, the second driving block 11 can only drive the knife-edge insert 30 outside the product 1, and the knife-edge insert 30 needs to be lengthened to lead to the outside of the product 1. In order to make the knife-edge insert 30 The force is balanced and the movement is smooth, and both ends of the force are required. In this way, the templates at both ends of the product 1 need to be widened, the size of the mold is correspondingly increased, and the cost of materials is correspondingly increased, and the knife-edge insert 30 is led outside the product 1, occupying the product. 1. For other parts, punching or forming could have been completed in this process, but due to insufficient positions, they were moved to the subsequent process to complete, which increased the process and increased the cost of the mold.
