Description

stamping equipment

technical field

The utility model relates to a production and processing equipment, more specifically, it relates to a stamping equipment.

Background technique

Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to separate it, thereby obtaining the required stamping parts. The commonly used stamping device for stamping is a stamping die, which is used in cold stamping. In processing, a special process equipment for processing materials into parts or semi-finished products is called stamping die.

When stamping the plate, referring to Figure 1, the operator holds one end of the plate 4 and pushes the other end of the plate 4 into the press 1, and then the press 1 impacts the plate 4, punching out stamped parts on the plate 4, because the stamping force is relatively high large, so that the plate 4 vibrates at the end of the press 1, and the vibration is transmitted along the plate 4 to the end held by the operator. The vibration amplitude of the plate 4 gradually increases from the end of the press 1 to the end of the operator. The operator holds the largest part, and if the operator is a little careless, the plate 4 will be separated from the operator's hand. In order to prevent the above situation, the factory generally installs a pressing plate 5 on one side of the press 1, and the pressing plate 5 is located on the operator's side. Between the press machine 1 and the press machine 1, a compression rod 6 is arranged. When the press machine 1 stamps the plate 4, the plate 4 is simultaneously pressed by the stamping force of the press 1 and the compression rod 6 to compress the plate 4 on the press. The force on the clamping plate 5, during the process of transmitting the vibration of the plate 4 at one end of the press 1 to the direction of the operator, the middle part of the plate 4 is clamped between the clamping plate 5 and the clamping rod 6 and fixed, and the plate 4 The vibration of 4 ends at the pressing plate 5, and there is no vibration at one end of the operator's hand-held plate 4, so that the operator holds the plate 4 firmly for punching.

However, when the pressing bar 6 presses the plate 5 material 4 downward, the lower surface of the pressing bar 6 will hit the upper surface of the plate 4, causing the plate 4 to deform, reducing the quality of the plate 4, and causing the plate 4 to be punched by the press 1 The output size is not acceptable.

Utility model content

Aiming at the deficiencies in the prior art, the purpose of this utility model is to provide a stamping equipment that can process qualified stamping parts without vibration of the plate held by the operator.
