Description

Technical Field

[0001] The utility model relates to a punching and blanking continuous die, in particular to a punching and blanking continuous die without waste material blanking, belonging to the technical field of punching. Background Art

[0002] With the rapid development of my country's national economy, the mold, an industrial aircraft carrier, plays an important role. The stamping mold processing has high production efficiency, convenient operation, easy mechanization and automation. The mold ensures the size and shape accuracy of the stamping parts, stable quality and long service life. The mold can process parts with a large size range and complex shapes, and no other heating equipment is required during the production process.

[0003] When punching the circular seat plate of the bench, the circular seat plate is conveyed to the lower mold by the conveying mechanism, and then punched by the upper mold. However, most of the existing equipment does not have a limit function for the circular seat plate. During the downward movement of the upper mold, the circular seat plate may be affected by the vibration amplitude of the equipment, and may be offset and misaligned on the lower mold, resulting in deviations during punching, which reduces the practicability of the device. In addition, after the processing of the circular seat plate is completed, personnel may need to manually remove the circular seat plate, which is an inconvenient operation. Utility Model Content
