Bending scratch-proof structure

Abstract

A bending scratch-proof structure comprises a bending floating block. A second bending embedded block is installed at one end of the bending floating block, a 90-degree bending face is arranged at one end of the second bending block, the first right-angle face of the second bending embedded block is flush with the upper plane of the bending floating block, a material belt is arranged on the second bending embedded block and the bending floating block, a bending male die which is matched with the first bending embedded block and the bending floating block is arranged on the upper portions of a first bending embedded block and the bending floating block, a rolling needle is installed on the second right-angle face of the second bending embedded block, and the rolling needle rolls along the second right-angle face of the second bending embedded block. The bending scratch-proof structure is reasonable in structure, simple and convenient to operate, and makes contact with the surface of the material belt through the rolling needle from beginning to end, so that scratch of the surface of the material belt is effectively avoided, processing quality of the products is ensured, and processing requirements are met. In addition, molding can be achieved for one time simply by using one set of molding dies, the trouble operation that two sets of molding dies are required to be adopted in the prior art is avoided, cost is reduced, and working efficiency is improved.

Description

technical field [0001] The invention relates to a mold device, in particular to a bending anti-scratch mold structure. Background technique [0002] In the bending mold, the bending surface of the product is often scratched. In many bending product processes, some bending surfaces are required to have no scratches, and the appearance requirements are relatively high. [0003] In the existing technology, such as figure 1 and figure 2 As shown, two sets of bending molds are usually used, which are pre-folding molds and forming molds, such as figure 1 As shown, the structure of the bending mold is: including a bending floating block 3, a first bending block 4 is installed at one end of the bending floating block 3, and one end of the first bending block 4 is set There is a 45° slope, and the first bending block 4 is provided with an angle of 135° between the end of the first bending block 4 and the bending block 3, and the strip is placed on the first bending block 4 and t...

AI Technical Summary

Problems solved by technology

[0005] When bending, the pre-bending mold bends the product to 45°, and then uses the forming mold to shape the product to 90°, which can greatly improve the stability of the bending mold, but during the bending process, the bending of the product The surface is always in contact with the surface of the bending block, and the surface of the product has large scars, which affects the quality of the product

It fails to effectively solve the problem of scratches on the bending surface and cannot meet the needs of product processing
