Embodiment Construction

[0008] like figure 1 As shown, the present invention includes a die structure 7, a punch 1, and the die structure 7 includes a die 4, a die base 8, and a support plate 5 is arranged between the die 4 and the die base 8, and the support plate 5 is provided with a guide post 3 and a ejector rod 2, there are two guide posts 3, the ejector rod 2 is arranged between the two guide posts 3, and a spring 6 is pressed between the support plate 5 and the die base 8 .

[0009] The punch 1 goes down, the workpiece contacts the ejector rod 2, the spring 6 is compressed by the external force, and the rebound force of the spring 6 acts on the die 4, so that the die 4 contacts the workpiece smoothly and slowly, slowing down the forming speed of the workpiece. During the forming process, its periphery always maintains a continuous and uniform pressing force, which effectively prevents the wrinkling phenomenon, improves the appearance quality of the workpiece, and makes it meet the design requ...

Abstract

The invention provides a shape pressing die of a wall board of a motor tractor. The die enables the wall board to be evenly stressed in the formation process, removes wrinkling, ensures appearance quality and meets design requirements. The die comprises a recessed die and a protruding die. The recessed die is installed on a base of the recessed die. The shape pressing die is characterized in that a support board is arranged between the recessed die and the base of the recessed die, a guide column and a material ejection rod are arranged on the support board, and a spring is installed between the support board and the base of the recessed die.

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...
