Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology and relates to a continuous stamping device. Background Technology

[0002] Stamping is a widely used metal forming process that uses a stamping press to apply pressure to a metal sheet using a die, causing it to undergo plastic deformation to obtain a workpiece of the desired shape and size. This process offers advantages such as high production efficiency, good material utilization, and high product consistency, and is widely used in various fields including automobile manufacturing, home appliance production, electronic equipment, and aerospace.

[0003] In industrial production, stamping presses are the core equipment for realizing the stamping process, and their performance directly affects product quality and production efficiency. Stamping presses can be classified according to their structure into mechanical, hydraulic, and servo-driven types; and according to the form of the worktable into open and closed types. Among them, continuous stamping presses, due to their ability to achieve automatic feeding and continuous stamping operations, demonstrate significant advantages in mass production.

[0004] Continuous stamping presses are typically used in conjunction with coil or strip materials for automated production. A feeding device delivers sheet metal into the die area at set intervals, completing multiple stamping processes such as punching, blanking, drawing, and bending during a continuous stroke, significantly improving production cycle time and material utilization. However, these machines are mostly used in large-scale industrial production, have complex structures, and high investment costs, making them unsuitable for small-batch or highly variable production needs.

[0005] In practical applications, a large number of small stamping presses are still widely used in small and medium-sized enterprises and repair workshops. These machines are simple in structure, easy to operate, and have low investment costs, making them suitable for processing small to medium-sized workpieces. However, most existing small stamping presses rely on manual loading and unloading operations. Operators manually place the sheet metal to be stamped onto the lower die, and then manually remove the finished product after stamping. This method of operation is not only labor-intensive but also poses certain safety hazards. Furthermore, the limited speed of manual operation results in low overall stamping efficiency.
