Description

technical field

[0001] The invention relates to a forming die structure of a tractor body workpiece, in particular to a tractor wall plate pressing die. Background technique

[0002] Tractor siding is characterized by workpiece asymmetry. When using the existing pressing die to make the tractor wall panel, the center of the part and the center of the die do not coincide, and the force is uneven during the forming process, resulting in wrinkling of the parts after pressing, resulting in poor appearance quality of the workpiece, which does not meet the design requirements. SUMMARY OF THE INVENTION

[0003] In view of the above problems, the present invention provides a tractor wall plate forming die, which can balance the force of the wall plate during the forming process, eliminate the wrinkling phenomenon, ensure the appearance quality, and meet the design requirements.

[0004] The technical scheme adopted in the present invention is: it comprises a concave die and a con...
