Bending mechanism, method for making bending plate through bending mechanism and bending plate

Abstract

The invention provides a bending mechanism, a method for making a bending plate through the bending mechanism and the bending plate. A transition folding edge is arranged on the secondary bending position of the bending plate, when a primary folding edge is bent, the transition bending edge is not bent, the circumferential primary folding edge is broken at the secondary bending position, when thesecondary folding edge is bent, the phenomenon that due to extrusion of the primary bending edge, the crossing position of the secondary bending position and the primary folding edge protrudes outwards is avoided, the non-bent transition folding edge is bent through the bending mechanism, the bending mechanism comprises a first sliding block unit, the first sliding block unit comprises a first sliding block capable of moving in the first direction, the first sliding block moves to extrude the transition folding edge in the first direction to enable the transition folding edge to be bent in thefirst direction, and the first direction and the bending direction of the primary folding edge of the bending plate point to the same side of the bending plate. Accordingly, the technical problem that the product protrudes outwards on the crossing position of the secondary bending position and the primary folding edge is solved while bending of all folding edges of the bending plate is achieved.

Description

technical field [0001] The invention relates to the technical field, in particular to a bending mechanism, a method for making a bent plate by using the bending mechanism and the bent plate. Background technique [0002] At present, sheet metal parts often have a small hem on the bend, that is, a primary hem on the secondary hem. The traditional method is to fold a whole circle of the small hem first, that is, to fold a whole circle of the primary hem first. , and then fold the large bend of the product, that is, fold the secondary edge again, and the product will often bulge outward at the intersection of the bend, such as figure 1 As shown, the position where the secondary bending position 301 meets the primary hem, that is, the position B in the figure bulges outward, and this defect seriously affects the appearance of the product. Contents of the invention [0003] In order to solve the technical problems in the prior art, the present invention provides a bending mech...
