Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of stamping dies, more particularly to a modular automatic feeding and automatic receiving stamping die. BACKGROUND

[0002] In modern manufacturing, stamping process as an important part of metal processing is widely used in many fields such as automobile, household appliances, electronics, etc. With the accelerating development of production automation and intelligentization, the performance requirements of stamping dies are increasingly improved, especially in production efficiency, precision control and automation level. However, the stamping dies widely used in the current market often have difficulty in balancing continuous operation and accurate positioning, which directly affects the overall efficiency of the production line and product quality.

[0003] Many traditional stamping dies can achieve a certain degree of automated production, but they have obvious shortcomings in continuous operation. These dies usually need to be reloaded manually or semi-automatically after each stamping, resulting in production interruption and reducing overall production efficiency. Even if some dies are equipped with automatic feeding mechanisms, they often have problems such as mismatch between feeding speed and stamping rhythm, inaccurate material positioning, etc., which affect the stability and efficiency of continuous operation. Accurate positioning is the key to ensuring the quality of stamped parts. Although some high-end stamping dies can achieve high-precision positioning in single stamping, they cannot realize continuous operation, have low stamping efficiency, and due to factors such as material deformation, mechanical wear, vibration interference, etc., the positioning accuracy is difficult to maintain for a long time. The way of relying on manual adjustment of positioning not only has low efficiency, but also increases the risk of human error, which is difficult to meet the production demands of large scale and high precision.
