Abstract

The invention discloses a drawing method for a U-shaped drawn component. During a drawing process, only two long edges of a preformed material are separately provided with pressing materials. According to the drawing method, during the drawing process, only the two long edges of the preformed material are separately provided with the pressing materials to form pressing ribs, so that phenomena of corrugation and deformation do not happen on the two ends of the drawing-moulded U-shaped drawn component; and the problems of poor flatness and corrugation of the U-shaped drawn component are effectively improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a U-shaped stretching method and a stretching die. Background technique [0002] At present, more and more products need to be stretched in hardware products. There are often problems of wrinkling and poor flatness in stretched parts with long U-shaped structures. In the prior art, negative gap stretching is adopted in the mold structure, nitrogen springs are added in the stretching mold to increase the material pressing force during stretching, etc., but the improvement effect is still not good, and the material flow cannot be solved well. Some positions of the tensile structure require good material flow, and some positions do not require material flow, but the existing mold structure cannot solve this problem. In the prior art, pressure ribs are also used to prevent the material from running around the edge area of ​​the product, but if figure 1 Shown is the s...
