Description

Technical Field

[0001] This utility model relates to the field of stamping technology, and in particular to a safety protection device and a stamping production line for stamping operations. Background Technology

[0002] Stamping, a common metal processing method, is widely used in the automotive, electronics, and home appliance industries. However, stamping operations pose certain safety hazards, especially in high-frequency, high-intensity production environments where workers face significantly increased risks. Operating a stamping press typically involves high-speed movement of molds and workpieces; improper operation or equipment malfunction can lead to serious personal injury and property damage.

[0003] Currently, there are some safety protection devices on the market, such as safety doors and light curtains, designed to reduce safety risks in stamping operations. Among them, safety doors are mainly used for isolation to prevent human parts from entering or to prevent injury from flying debris due to mechanical malfunctions, which is a passive protection. Safety light curtains are used to automatically stop the stamping press when human parts or objects enter the working area, which is also a passive protection. Some stamping machines rely solely on manual control by the operator and do not have an automatic safety stop mechanism. In the event of an emergency, the operator may not be able to react quickly, thus increasing the risk of injury.

[0004] Therefore, existing safety protection technologies often suffer from drawbacks such as slow response speed, limited protection range, complex operation, and lack of flexibility, which cannot effectively meet the high safety requirements of modern production. In particular, traditional safety protection devices fail to provide sufficient warnings and protection in the event of equipment failure or misoperation, leading to accidents, insufficient protection of operator safety, and impact on work efficiency.

[0005] There are no effective solutions yet for the problems that existing safety protection measures in related technologies have, such as passive protection, slow response speed, complex structure that is inconvenient to maintain, and lack of flexibility that affects operation efficiency.

The first support element 42 supports the upper slider of the stamping device, so that the stamping die cannot be closed, preventing the upper slider of the stamping device from falling back again and causing injury to the operator due to misoperation. After the operation is completed in the manual mold, the drive element 51 pushes the third movable element 31 to drive the first support element 42 to slide in the opposite direction according to the preset displacement, and the mold can be closed to complete one stamping.

[0180] The technical effects of this utility model are as follows:

[0181] The second movable unit is driven by a drive unit to slide relative to the first movable unit, thereby driving the first support unit to reciprocate and support the upper slide of the stamping device, preventing the stamping die from closing. The base unit stabilizes the first movable unit and the drive unit, making the sliding of the second movable unit more stable and smooth. It actively protects and responds promptly to hazardous work areas, solving the problems of passive protection and slow response speed of existing safety protection measures. Moreover, the structure is simple, flexible and convenient to use, and designed with a detachable connection, making it easy to disassemble and clean. It not only effectively protects the safety of workers and improves the safety and reliability of the equipment, but also reduces costs and improves work efficiency, solving the problems of complex structures that are inconvenient to maintain and lack of flexibility that affect work efficiency.
