Problems solved by technology
The upper mold (ie punch) and the lower mold (ie concave mold) of the existing stringer forming mold tend to rebound during compression molding, which leads to unqualified production of the product stringer and affects the service life of the product
In the actual production process, due to the high yield strength of the girder slab, there is a tolerance in the thickness of the material, there is a deviation in the forming of the formed longitudinal beam, and there is a large gap between the beam closing operation and the front and rear beams, which does not meet the quality requirements and is time-consuming and laborious. Low efficiency and inconvenience to work

The invention discloses a stamping and forming mold for an automobile longitudinal beam, which comprises a lower mold assembly, an upper mold assembly and four spacer posts, and the lower mold assembly includes a lower mold base, a lower die, a lower mold insert, The ejector block guide plate and the ejector rod; the upper mold assembly includes an upper punch, an upper mold fixing plate, and a plurality of upper punch inserts; the lower die is installed on the lower die base, and the lower end of the limiting column is connected The mold base is connected, the upper punch is installed on the fixed plate of the upper mold, the shape of the upper punch matches the shape of the lower die, the lower die is provided with a top plate, the top plate is installed in the cavity of the lower die and Corresponding to the upper mold, an ejector rod is arranged between the lower die and the ejector plate. The present invention has the advantages of high blanking efficiency, good manufacturing precision and is suitable for mass production without deformation rebound phenomenon when the upper die and the lower die of the automobile longitudinal beam forming die are formed.
Description
technical field [0001] The invention relates to the technical field of automobile stamping dies, in particular to an automobile longitudinal beam stamping forming die. Background technique [0002] The frame of the car is mainly composed of longitudinal beams and beams. The cross-section of the light truck frame longitudinal beams is mostly U-shaped, which is composed of upper and lower end flanges welded to the web. Under the conditions of use, the longitudinal beam as the main component of the frame bears various complex loads from the road and loading, and the strength, stiffness and life of the frame longitudinal beam are very important in the overall design of the car. The upper mold (ie punch) and the lower mold (ie concave mold) of the existing stringer forming mold tend to bounce back during compression molding, which leads to unqualified production of the product stringer and affects the service life of the product. In the actual production process, due to the high...
