Abstract
The invention relates to the field of vehicle part processing, and discloses a processing method for longitudinal beam components, including: first step, drawing the sheet material to form a strip-shaped protruding top surface (1) and the a transition bevel (2) on the first side of the first end of the top surface (1), the transition bevel (2) transitions the top surface (1) to the undeformed portion of the panel; second order, positive Cutting off the excess part and punching; the third step, preliminary shaping to obtain the side wall surface and the flanging surface; the fourth step, shaping the side wall surface corresponding to the transition slope (2), so that the side wall surface The ends are bent to form the side flanging surfaces (5), and the whole is precisely shaped. Through the above technical solution, the drawing process forms the side wall surface and the flanging surface into a transition slope, and the operation of cutting excess waste can be completed only through the tangential process, which saves the side cutting operation, reduces the process, and saves mold debugging time and mold cost.
Description
technical field [0001] The invention relates to the processing of vehicle components, in particular to a processing method for longitudinal beam components. Background technique [0002] Due to the improvement of automobile exhaust emission standards and the continuous reduction of fuel consumption, reducing the weight of automobiles is one of the most basic ways to save energy and improve fuel economy. The use of high-strength steel plate body can reduce the thickness of the plate under the same strength design condition, thereby reducing the weight, so as to realize the weight reduction of the body. [0003] As a structural part using high-strength steel, the rear longitudinal beam of an automobile is one of the important body parts. However, the formability of high-strength steel is poor, and its processing procedures are relatively many. The mold manufacturing cost is high and the debugging time is long, so the process is reduced. It is particularly important to improve...
