A kind of beveled edge sheet metal mold

Abstract

The invention discloses a beveled edge sheet metal mold, which comprises: a lower mold, the lower mold is provided with a first groove, a second groove is arranged in the first groove, and the first groove The left and right sides of the upper mold are provided with side grooves; the upper mold is provided with installation arc grooves on both sides of the upper end of the upper mold, and installation grooves are arranged in the installation arc grooves, and the upper mold is arranged above the lower mold; Hemming die, the side wall of the hemming die is provided with a hemming groove, the side wall of the hemming die is provided with a mounting protrusion matching the installation groove, and the hemming die is rotatably installed on the Install in the arc groove; return spring, one end of the return spring is fixed in the installation groove, and the other end is fixed on the installation protrusion, and the return spring pulls the folding die; side mold, the The side molds are slidably installed in the side grooves; fast, stable and accurate production of sheet metal parts is realized, and the structural strength and service life of the sheet metal parts are improved.

Description

technical field [0001] The invention relates to the field of mold equipment, in particular to a sheet metal mold for oblique folding. Background technique [0002] Sheet metal parts use the ductility and fluidity of metal materials to stamp, bend, stretch, and cut the sheet metal to produce products of various shapes. [0003] When bending corners of existing sheet metal parts or prefabricated sheet metal parts, the two ends of the bending part are generally fixed. When bending and forming, the bending part is usually thinner than the ordinary part. For the process without free ends (fixed at both ends), the thickness of the bending part is thinner, and the performance of the sheet metal parts produced in this way is poor. , used as a stressed fastener, it is easy to fatigue and fracture. [0004] For the existing inner-folding sheet metal equipment, when performing inner-folding processing on small sheet metal parts, the bending process is generally carried out through mu...

AI Technical Summary

Problems solved by technology

When bending and forming, the bending part is usually thinner than the ordinary part. For the process without free ends (fixed at both ends), the thickness of the bending part is thinner, and the performance of the sheet metal parts produced in this way is poor. , used as a stressed fastener, easy to fatigue fracture

[0004] For the existing inner-folding sheet metal equipment, when performing inner-folding processing on small sheet metal parts, the bending process is generally carried out through multiple molds at the same time, and the bending process is carried out step by step, so there is a free end, but the equipment itself is too complicated , and for large sheet metal parts, the cost and efficiency are relatively poor, such as: sheet metal parts that need to make right-angled edges first and then make inner folds
