Embodiment Construction
[0021] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0022] see figure 1 As shown, the inflection point rectification method for the shaping of automotive longitudinal beam stamping parts described in the embodiment of the present invention is mainly applicable to longitudinal beam parts of U-shaped structure, and the longitudinal beam parts have flange shaping but no rollover The edge shaping mold must use the inflection point rectification method of the present invention under the condition that the R angle is enlarged without affecting the quality of loading and solder joints. see figure 1 , the inflection point rectification method is in the U-shaped longitudinal beam flanging shaping process, the R angle of the rebound of the U-shaped longitudinal beam corresponding in the punch 2 ...

The invention discloses a turning point improving method for reshaping a vehicle longitudinal beam type stamping part and a device special for the method, belonging to the stamping field. According to the embodiment of the invention, a second R angle is added in a convex mould in a turning and reshaping process and repairing welding treatment is carried out in corresponding positions of a concave mould, so that the turning point improving method is used under the condition that all procedures of a longitudinal beam can not be used for carrying out lateral shaping through adding tapered wedges. During the use, the concave mould moves downward, and the convex mould is fixed, a flanging insert of the concave mould enables a flanged side of a workpiece to be shrunk inward through an inward-shaping force of turning points at two sides of the U-shaped longitudinal beam, therefore, the whole flanged side is shrunk inwards for preventing from externally rebounding. Thus, no mould mechanism is added in the embodiment of the invention and a stamping process and the newly-added mould are not changed, thus the technical cost is reduced. The turning point improving method has the advantages of high improving speed and remarkable effect; and the quality of the whole vehicle is not influenced by the rebounding of the improved vertical beam.
Description
technical field [0001] The invention relates to a method for rectifying stamping parts, in particular to a method for rectifying inflection points for shaping automobile longitudinal beam stamping parts and a special device thereof. Background technique [0002] With the rapid development of the automobile industry, the product quality requirements for automobile longitudinal beam stamping parts are getting higher and higher. Existing automobile longitudinal beam stamping parts have a U-shaped structure and are stamped from high-strength steel plates. Due to the thick material of the high-strength steel plate itself, the deep drawing depth, and the relatively complicated stamping shape of the automobile longitudinal beams, the final stamped products The rebound of the parts is serious, which affects the matching effect of the body structure and the quality of the solder joints, and even ultimately affects the quality of the vehicle.
