Description

Technical Field

[0001] This utility model relates to the field of continuous stamping die technology, and in particular to a continuous stamping die for automotive tube beam fittings. Background Technology

[0002] Progressive stamping dies, also known as step dies, step-by-step dies, transfer dies, or continuous dies, are a type of die used on large presses for continuous production. These dies are characterized by high efficiency, high precision, and high stability, making them particularly suitable for producing high-volume products such as body parts, appliance housings, and construction machinery components.

[0003] The existing Chinese patent CN215587663U, entitled "A Continuous Stamping Die for Automotive Tube Beam Fittings," proposes that the operation of a motor can drive the moving plate and the die to move intermittently on the processing table, eliminating the need for manual die movement and thus reducing the risk. However, in actual use, the applicant found that the movement of the die leads to a decrease in stamping accuracy and affects the quality of the stamped product, indicating certain shortcomings in its use. Therefore, we propose a continuous stamping die for automotive tube beam fittings. Summary of the Invention
