Description

Technical Field

[0001] The present invention relates to the technical field of side stamping, and specifically provides a side stamping device for automotive parts and its usage method. Background Art

[0002] Stamping is a forming process method that applies external force to plates, strips, tubes, profiles, etc. by a press and a die, causing them to undergo plastic deformation or separation, thereby obtaining workpieces with the required shapes and sizes. For parts with relatively complex shapes, multi-station progressive dies often need to perform side stamping on a certain part or some parts of the part. The mechanism for completing side stamping processing is mainly achieved by a cam and slider mechanism. With the continuous expansion of the automotive parts market, stamped parts in automotive parts account for a large proportion, and side stamping is one of them.

[0003] In the prior art, for example, Chinese Patent Application CN111842664A discloses a side stamping device for automotive parts, including an upper die pressing mechanism and a lower die pressing mechanism adapted to be used in cooperation; the lower die pressing mechanism includes a stamping punch and a punch driving mechanism; the stamping punch is adapted to stamp the side wall of the workpiece; the punch driving mechanism includes a lower slider adapted to drive the stamping punch to move linearly, a cam in contact with the lower slider, and a fifth spring in contact with the lower slider and adapted to be compressed and deformed as the stamping punch moves linearly; the cam and the lower slider are in cooperation through an inclined surface to drive the stamping punch to generate a horizontal movement through the vertical movement of the cam. The side stamping device for automotive parts of this invention has a long service life and can improve the consistency of the processed automotive parts.

[0004] However, in the prior art, the above-mentioned side stamping device focuses on introducing the movement of the slider and the cam to drive the stamping punch for side pressing. However, in the actual operation process, compared with the traditional vertical stamping method, the placement and fixation of the sheet material during side stamping will be more complex and difficult. If the position of the sheet material is incorrect and the fixation is not firm enough, the sheet material will have a large displacement, which will directly affect the quality and effect of side stamping. In severe cases, it will lead to stamping failure. Summary of the Invention
