Mold with swing type stripping structure

Abstract

The invention discloses a mold with a swing type stripping structure. A bending mold matches with a bending slider to form a covered edge of a workpiece to be processed, notches are disposed at the end, which is attached to the workpiece to be processed, of the bending mold, and a swing part capable of forming a convex closure in the covered edge is rotationally connected into the notch, and is properly arranged in the notch so that the swing part can vertically swing. The swing part is provided with a first limiting surface and a second limiting surface which respectively limit two lateral edges of the swing part when the swing part swings, the covered edge is bent when the swing part swings so that an end surface of the swing part is abutted onto the first limiting surface, the bending mold moves inwards to withdraw materials after the covered edge is bent, at the moment, the swing part swings outwards in the notch to be separated from the first limit surface, and accordingly, the materials can be prevented from being jammed in the convex closure and cannot be withdrawn. The mold is simple in structure and convenient in operation, the problems of incapability of withdrawing materials and bending deformation during stretching of a shell part with a convex closure and a covered edge in an existing mold are resolved, and the production quality of a product is guaranteed.

Description

[0001] technical field

[0002] The invention relates to a mold with a swinging stripping structure.

[0003] Background technique

[0004] The outer shell of some square metal boxes is generally obtained by stretching sheet metal parts. In order to meet the needs of installation, some outer shell parts need to have a certain hemming on the side, and some outer shell parts need to be provided with convex edges. Bags, because the processing efficiency of the traditional method of stretching first and then wrapping is too low, so it is necessary to use one-time stretching. However, in the prior art, in the one-time stretching process of this type of shell parts, the mold often has the problems of non-returning and bending deformation at the edge, which seriously affects the production quality of the product.
