Description

Technical Field

[0001] The utility model belongs to the technical field of sheet metal processing, in particular to a punching device for sheet metal parts. Background Art

[0002] Sheet metal fabrication is a key branch of metalworking, encompassing a range of processes such as shearing, punching, bending, and welding on thin metal sheets.

[0012] Beneficial effects of the utility model:

[0013] 1. The utility model provides a stamping device for sheet metal parts. By starting a servo motor, the servo motor drives the lead screw to rotate, and due to the engagement of the lead screw and the sliding sleeve, the lead screw drives the sliding sleeve to move linearly during the rotation process. At the same time, the sliding sleeve drives the moving seat to move together, and the moving seat drives the slider to move together. During the movement of the slider, the slider always maintains a tight engagement with the guide rail, so that the movement of the moving seat is more stable.

[0014] 2. The utility model provides a stamping device for sheet metal parts. When the cylinder drives the die to stamp the sheet metal part on the bottom die, the die, the sheet metal part and the bottom die first come into contact. After contact, as the cylinder pushes, the die, the sheet metal part and the bottom die continue to move vertically downward until the bottom of the bottom die comes into contact with the buffer pad. The buffer pad cushions the impact force on the bottom die, thereby preventing the sheet metal part from being offset during stamping. BRIEF DESCRIPTION OF THE DRAWINGS
