Embodiment Construction
[0050] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0051] The present invention firstly provides a Figure 1-2 The sheet metal part shown is integrally formed by sequentially connecting the first body part 1, the flat part 2 and the second body part 3; the first body part and the second body part are arranged symmetrically and parallel to each other, and are both perpendicular to the flat part; A body portion includes a first body 4 and a first flange portion 5 formed by bending vertically outward from the periphery of the first body; a second body portion includes a second body 6 and a vertically outward bend from the periphery of the second body The formed second flange portion 7 ; the bending direction of the first flange portion relative to the first body is opposite to the bending direction of the second flange portion relative to the second body. There are ribs 8 protruding toward the second body on th...

The invention provides a stamping part and a processing method thereof. The stamping part belongs to n-shaped beam-type stamping parts which are applied to nut reinforcing plates of front towing hooks of a vehicle model and are provided with asymmetric ribs. The processing method sequentially includes blanking, stamping ribs, folding a right-angle profile on one side, folding profiles on the periphery, folding a right-angle profile on the other side and punching. By the processing method, stamped parts are all qualified, and the stamping forming problems such as rib overlaying, hole-site deviation, hole deformation, hole dimension out-of-tolerance, profile deviation and height difference of profiles on two sides are completely solved. The invention further provides a stamping die for the processing method. The stamping die is simple in structure, convenient to process, manufacture and use and easy to change; by the stamping die, qualification rate of the stamping parts is increased, and stability of the stamping parts is improved.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a sheet metal part, a processing method of the sheet metal part and a stamping die used in the processing method. Background technique [0002] In the past, the production of several-shaped beam parts was completed in four steps. For example, the first process is blanking, the second process is punching ribs and turning the periphery, the third process is punching, and the fourth process is folding. The sides are at right angles to the profile. Such a four-sequence stamping process is more practical for beam-type sheet metal parts that are more symmetrical in shape, and can manufacture and process qualified beam-type sheet metal parts. However, for beam-type sheet metal parts with asymmetrical shapes, many openings on the sheet metal parts and / or asymmetric arrangement of ribs, qualified parts cannot be produced in such a four-sequence, and ribs often appear. Quality proble...
