Problems solved by technology

Once chip skipping occurs, it will leave crush marks on the surface of the product, and produce defective products in batches. In severe cases, it may cause the edge of the knife to crack or break, and may even cause cracks in the template

Embodiment Construction

[0014] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0015] see figure 1 and figure 2 , the blanking structure of the lower mold for preventing chip skipping of the present invention includes: a blanking area 1 and a chip storage area 2 located below the blanking area 1, the section of the blanking area 1 is a non-true circle, and the section of the chip storage area 2 It is circular, and the cross-section of the blanking area 1 is smaller than the cross-section of the debris storage area 2.

[0016] Among them, the cross section of the blanking area 1 is non-circular, so that the waste chips are deformed, which effectively avoids the traditional shape of waste chips, such as the round waste chips that rotate during the blanking process, resulting in the problem of chip jumping.

[0017] Specifically, see figure 1 and image 3 , the outline of a non-true circle includes: multiple arcs ...

Abstract

The invention discloses a lower die blanking structure with a scrap jumping prevention function. The lower die blanking structure is characterized by comprising a blanking area and a scrap storage area positioned below the blanking area, the section of the blanking area is non-circular, the section of the scrap storage area is circular, and the section of the blanking area is smaller than that of the scrap storage area. The lower die blanking structure with the scrap jumping prevention function has the advantages that the lower die blanking structure is simple, is low in manufacturing cost, and can effectively prevent scraps from jumping out of a die surface, so that influence of scrap jumping to yield of products is avoided.

Description

technical field [0001] The invention relates to a blanking structure of a lower die, in particular to a blanking structure of a lower die for preventing chip jumping, and belongs to the field of mechanical processing. Background technique [0002] Punching is a common processing procedure in machining, and chip skipping is a common bad phenomenon in punching. The so-called skipping chip refers to the part that is separated from the product in the punching process, that is, the waste chip. Its size and shape are the same as the blanking structure of the lower die. The phenomenon that the upper mold jumps out of the mold surface. Once chip skipping occurs, it will leave crush marks on the surface of the product, and produce defective products in batches. If it is serious, it may cause the edge of the knife to crack or break, and may even cause cracks in the template. Therefore, chip skipping has always been a problem that design and production personnel in the field of machi...
