Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a stamping machine with a mechanical protection device. Background Technology

[0002] A stamping press is a mechanical equipment that applies pressure to metal sheets, strips, and tubes through a die, causing them to undergo plastic deformation and separation, thereby realizing punching, blanking, bending, stretching, and forming processes. Due to its efficient and precise processing characteristics, it is widely used in the fields of automobile manufacturing, electronic equipment, aerospace, and hardware products. Stamping presses with mechanical protection devices are important facilities in industrial equipment that isolate dangerous mechanical areas and protect the safety of operators and equipment through protective devices. The core design of mechanical protection devices is to prevent personnel from contacting dangerous moving parts through physical barriers, interlocking controls, and automatic protection, while ensuring the normal operation of the production process.

[0003] Existing mechanical protection devices use fixed protective barriers to form a closed area around the press workbench, with anti-slip bases to prevent displacement. However, the fixed barrier is rigidly connected to the press body by welding and bolts. This means that maintenance of transmission components requires dismantling the barrier structure, resulting in low maintenance efficiency. Disassembling bolts during mold replacement and equipment maintenance is time-consuming. Existing technology uses a pin-type connection structure between the posts and panels of the protective barrier. Slots are made in the posts, and pins are installed on the panels. During installation, the pins are inserted into the slots to fix the panels, and during disassembly, the pins are pulled out to quickly remove the panels. However, the press expands linearly due to mechanical load and temperature rise during operation. Since the fixed barrier cannot follow the deformation, it becomes rigidly constrained, leading to dynamic deformation of the equipment, resulting in stress concentration and fatigue failure. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a stamping machine with a mechanical protection device, which aims to improve the problem that in the prior art, the bolts of fixed fences cannot be quickly disassembled during maintenance, and the fixed bolts will not be able to deform due to the long-term mechanical load and temperature rise of the stamping machine, resulting in stress concentration and damage to the structure caused by dynamic deformation of the equipment.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a stamping machine with a mechanical protective device, including a protective cover. A dust collection mechanism is installed on the lower left side of the bottom wall of the protective cover. The dust collection mechanism is used to clean debris from the workbench. A self-locking mechanism is slidably connected to the left and right sides of the front end of the protective cover. The self-locking mechanism is used to fix the protective cover. A folding door mechanism is installed on the lower front side of the protective cover. The folding door mechanism is used to extend and retract the protective railing. The folding door mechanism includes a retractable door, which is installed on the lower front side of the protective cover. A slide groove is slidably connected to the upper end of the retractable door. Hinges are installed on both the upper and lower ends of the right top wall of the retractable door.
