Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] see Figure 3 ~ Figure 5 , introduce the bending manufacturing method of the metal plate of the present invention, it is to adopt the integrated technology of twice cold extrusion and metal cutting processing successively, realize the shape of the stamping component without arc angle, that is, the curved outer surface of the component is a right angle; the method Including the following process steps:

[0025] (1) The metal plate 10 is bent for the first time by using a punching machine and cold extrusion process: the metal plate 10 is extruded and bent to 45±5 degrees, and extruded at the bending deformation part of the metal plate marked with a circle in the figure A small step 11 is formed; the height of the small step 11 is 0.15 to 0.20 times the thick...

Abstract

The invention discloses a metal plate bend preparing method, which comprises the following steps: adopting twice cold extrusion and metal cutting handling synthesis craft; realizing extrusion component appearance without circular arc angle (the bend external surface of component is right angle), wherein the thickness of metal plate is low steel with the thickness smaller or equal to 3mm, copper, copper alloy, aluminum and aluminum alloy and other low hardness non-ferro metals. The invention reduces the cost, which makes the production more delicate and beautiful.

Description

technical field [0001] The invention relates to a bending manufacturing method of a metal plate, in particular to a bending manufacturing method in which the bent outer surface of the bent metal plate is a right angle, and belongs to the technical field of metal rolling. Background technique [0002] As we all know, stamping and bending of metal plates is a widely used traditional mechanical process. It uses the mechanical properties of plastic deformation of metal materials and the process performance of forging deformation to bend metal plates on stamping equipment and molds. Due to the plastic deformation of the metal material, after the stamping and bending process, a circular arc corner will inevitably be left on the outer surface of the stamping and bending deformation part of the metal plate. figure 1 (A) and (B) respectively show the metal plate without using the pressure plate (the concave and convex molds 1 and 2 are V-shaped structures) and the metal plate with th...
