Upward bending correction mechanism

Abstract

The invention relates to an upward bending correction mechanism which comprises an upper die seat. An upper die component and a correction male die are sequentially arranged under the upper die seat. The upward bending correction mechanism further comprises a lower die seat, and a lower die component and a correction female die paired with the correction male die are sequentially arranged on the lower die seat. A first wedge rod is horizontally arranged at one end of the upper die seat. A second wedge rod is vertically arranged at one end of the upper die seat. The top end of the first wedge rod abuts against the upper end of the second wedge rod. A boss is arranged on the head portion of the left end of the correction female die, the left end face of the boss is provided with an inwards-concave slope, a spring groove is formed in the lower portion of the slope, and a wedged notch is formed in the right end of the correction female die. A groove opposite to the spring grove is dig in the middle of a female die fixing plate, and a spring is arranged in the groove and the spring groove. A workpiece is arranged between the correction male die and the correction female die, and the lower portion of the workpiece abuts against the top of a material lifting block. The upward bending correction mechanism can bend upwards the workpiece and adjust overdone bending, reduces bent scratches on the surface of a product, prolongs the service lives of the dies, and improves production efficiency.

Description

technical field [0001] The invention relates to the technical field of correcting molds, in particular to an upward bending correction mechanism. Background technique [0002] When the product is bent 90° once in the mold, because any metal material has bending resilience, the angle of the product after bending is greater than 90°, and the rebound angle of different materials is different, so it is difficult to meet the angle size required by the product design. In general, upward bending is more severe than downward bending, and it is difficult to bend upward to 90° in one step. In the prior art, the method of reducing the gap between the punch and die is usually used, which can effectively reduce the amount of rebound, but at this time the product The surface is easily scratched, the mold is severely worn, and the production efficiency is low. Contents of the invention [0003] In view of the shortcomings in the above-mentioned existing production technology, the applic...
