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

Embodiment 1

[0030] like Figure 1-Figure 3 As shown, an L-shaped aluminum profile arc bending mold according to the embodiment of the present invention includes a body 1, an upper template 2 and a lower template 3; the surface of the body 1 is slidably connected with an upper template 2; The bottom position of the surface and the upper template 2 is provided with a lower template 3; the top surface of the lower template 3 is provided with a shaped block 4; the top surface of the shaped block 4 is provided with a shaped groove 5; the inner surface of the shaped groove 5 is provided with A rotating groove 6; a rotating plate 7 is rotatably connected inside the rotating groove 6; a mounting groove is formed at the bottom of the rotating groove 6; a first spring 8 is fixedly connected to the inside of the mounting groove, and the first spring 8 It is fixedly connected with the turning plate 7; when working, when bending the aluminum profile, it is necessary to extrude the aluminum profile thr...

Embodiment 2

[0039] like Image 6 As shown, Comparative Example 1, in which another embodiment of the present invention is: the bottom surface of the rotating plate 7 near the guide hole 17 is fixed with a connecting rope 24; the surface of the shape block 4 is connected to the guide hole 17. There is a fixing slot at the position; the slot of the fixing slot is fixed with the elastic plate 25, and the connecting rope 24 passes through the shape block 4 and is fixedly connected with the elastic plate 25; the elastic plate 25 is connected to the bottom of the fixing slot. There is a spring piece 26 fixed between them; during operation, when the turning plate 7 rotates, the turning plate 7 will pull the connecting rope 24, and the connecting rope 24 will drive the elastic plate 25 to deform, so that the elastic plate 25 squeezes the spring piece 26. At this time, the guide hole 17 In the normal open state, when the rotating plate 7 is rotated to the inside of the rotating groove 6, under the...

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...
