[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] Example:

[0017] like Figures 1 to 4The upper plate shaping mold of the left upper control arm shown in the figure includes an upper template 1 and a lower template 2. The upper template and the lower template are parallel to each other, and a gap is left between the upper template and the lower template. A die 3 is installed on the lower template. The left half of the die is gradually concave from the leftmost side to the rightmost side of the die. The upper edge of its cross section is parabolic. The shape of the right half of the die is symmetrical to the shape of the left half. A square raised portion 31 is provided in the middle of the die. The four corners of the raised portion are chamfered in an arc shape. The upper edge of the raised portion is parallel to the lower edge. The left edge of the raised portion is an arc curved to the right, and the right edge of the raised portion is curved to the right. The arc is curved to the left, and the upper surface of the raised part is a concave arc surface. The upper surface shape of the left half of the die is adapted to the upper piece of the left upper control arm, and the upper surface shape of the right half of the die is adapted to the upper piece of the right upper control arm. A punch 4 is provided above the die, and the shape of the punch is adapted to the shape of the die. The punch is fixedly installed under the upper template. In order to improve stability, an upper pad 5 is also provided between the punch and the upper template. A plurality of positioning blocks 6 are also provided on the die. The positioning blocks are installed on the die by screws, and the positioning blocks play a role in positioning the workpiece.
