[0002] The stamping die is a special process equipment for processing the sheet into parts (or semi-finished products) in the cold stamping process. When the stamping die is stamping the sheet, it is necessary to press the sheet, usually through a pressing device, and the existing pressing device is a device for pressing the sheet before the stamping die is stamping the sheet. The pressing device is convenient for evenly applying force to press the sheet, and is also convenient for stable conveying after pressing, so as to improve the uniform force and pressing effect of the pressing device when the pressing device is pressing the sheet before the stamping die is stamping.

[0003] The existing pressing device is used for flattening before the stamping plate of the stamping die. The material plate is moved to the inside of the pressing device by rotating the roller, and the material plate is punched and flattened by pressing the pressing plate downward. Therefore, during stamping, when the pressing plate is directly driven to move by the cylinder, the cylinder presses the middle position of the pressing plate with force, so that the force on the edge of the pressing plate is weaker, thereby causing the edge of the pressing plate to be unevenly stamped against the edge of the material plate, affecting the uniform force of the pressing plate when the pressing device is pressing before the stamping operation of the stamping die. For this reason, the utility model proposes a pressing device for the stamping die. Utility Model Content
