A continuous metal mold split-type bending structure and bending forming method thereof

Abstract

The invention relates to a metal mold split bending structure, which provides a continuous metal mold split bending structure with simple structure, ingenious concept, which can adjust and ensure the verticality and flatness of the U-shaped metal stamping forming parts corner verticality and flatness. The bending forming method solves the technical problems that the U-shaped products in the prior art are prone to side wall outreach and the flatness of the bottom surface is not enough, which directly affects the quality of assembled products. It includes forming bending dies and a fillet forming punch inserted into the forming bending die, the forming bending die includes a left lifting die and a right lifting die, and the upper ends of the left lifting die and the right lifting die are jointly formed Forming cavity, at the corners of the bottom of the forming cavity corresponding to the left lifting die and the right lifting die, there are respectively provided with straight line forming fillets that match with the fillet forming punch, and the corresponding left lifting die and right lifting die below the forming cavity A lift pushing block is sandwiched between the dies.

Description

technical field [0001] The invention relates to a metal mold split bending structure, in particular to a continuous metal mold split bending structure with simple structure, ingenious concept, which can adjust and ensure the verticality and flatness of the U-shaped metal stamping forming parts corner verticality and flatness. Bending method. Background technique [0002] Metal stamping parts are widely used in various fields, including high-end electronic products, such as electronic devices, smart phone accessories, auto parts, etc. Among them, stamping parts play an important role, and their quality directly affects the quality of assembled products. Metal stamping parts usually rely on presses and molds to exert external force on the profile, so that the material is deformed or separated, and the stamping product of the required shape and size is obtained, that is, formed by stamping, stretching and shearing, so the mold The structure and processing technology directly d...
