L-shaped aluminum profile arc bending die

Abstract

The invention belongs to the field of arc bending dies, and particularly relates to an L-shaped aluminum profile arc bending die which comprises a machine body, an upper die plate and a lower die plate. The surface of the machine body is in sliding connection with an upper template; a lower template is arranged on the surface of the machine body and at the bottom of the upper template; a block is arranged on the top surface of the lower template; a shape groove is formed in the top surface of the shape block; a rotating groove is formed in the inner surface of the shaped groove; a rotating plate is rotationally connected into the rotating groove; a mounting groove is formed in the groove bottom of the rotating groove; a first spring is fixedly connected to the interior of the mounting groove, and the first spring is fixedly connected with the rotating plate; through rotation of the rotating plate, a large contact area is always kept between the rotating plate and the bottom face of the aluminum template, the problems of local concentrated stress of the aluminum template and change of the local stress position are reduced, then the problems of local deformation of the aluminum template and scratching of the surface of the aluminum template are reduced, and the forming quality of the aluminum template is improved.

Description

technical field [0001] The invention belongs to the field of arc bending molds, in particular to an L-shaped aluminum profile bending arc mold. Background technique [0002] As a commonly used material, aluminum profiles are usually first produced and processed into castings, forged products and their foils, plates, strips, tubes, bars, aluminum profiles, etc., and then cold-formed steel, sawing, punching, assembly, assembly, etc. It is made by coloring and other processes, in which cold bending is used as a common process to perform arc bending treatment on aluminum profiles. [0003] According to the publication number CN214022793U, an L-shaped aluminum profile arc bending die is formed by punching to form an L-shaped aluminum profile; by setting a first driving block, the upper die can be driven to perform punching work; by setting a clamping device, thereby During the punching process, the L-shaped aluminum profile can be clamped and fixed; by being provided with a clam...

AI Technical Summary

Problems solved by technology

This L-shaped aluminum profile bending mold solves the problems of traditional bending molds that require a lot of manpower, low production efficiency and poor bending effect

[0004] In the prior art, when bending an aluminum profile, it is necessary to extrude the aluminum profile through the upper template and the lower template to realize automatic bending, but during the bending process, the shape of the groove is fixed, and the aluminum profile in a flat state When the plate is first squeezed by the upper template, the bottom of the aluminum plate will be partially squeezed, and as the aluminum plate is bent and deformed, the bottom of the aluminum plate will also be subject to sliding friction, resulting in the bending of the aluminum plate Scratches on the surface of the template
