Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts stamping, and more specifically to an automobile parts stamping device with a protective function. Background Art

[0002] Auto parts refer to the various parts and accessories that make up a car, including the engine, gearbox, chassis, body, electrical system, etc. Auto parts stamping equipment is a device used to process auto parts, usually used to stamp metal sheets. The structure of the auto parts stamping equipment includes the following parts: frame, mold, transmission system and control system.

[0003] The existing stamping devices for automobile parts still have the following problems: the existing stamping devices involve high-speed moving mechanical parts, high-pressure hydraulic systems, etc. during operation, and the existing stamping method is that personnel place the workpiece on the mold and use the hydraulic pump to drive the upper mold to stamp the workpiece. However, in actual use, it is very easy for the machine to start suddenly due to improper operation by personnel, thus causing certain safety hazards, which brings great trouble to the use;

[0004] Secondly, existing stamping devices often need to perform stamping and forming on workpieces of various sizes or shapes. In this process, the mold often needs to be replaced. However, most existing molds are fixed by bolts, which results in the need to use professional tools to disassemble the mold every time it is necessary to replace the mold. This not only brings great labor intensity to the personnel, but also reduces their work efficiency. After the stamping is completed, the workpiece is often stuck in the forming groove, and the personnel need to manually remove the workpiece, which is very troublesome.

[0005] In view of this, we propose an automobile parts stamping device with protective function. Utility Model Content

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the utility model has the following advantages: when stamping automobile parts, the cylinder can be used to drive the moving seat to move, and during the movement, the connecting rod will move in the guide groove and press the protective door to open. At this time, the personnel will place the workpiece and use the through-screw motors on both sides to drive the limit plates to adjust so that the workpiece can be straightened. Then, the cylinder is used to drive the moving seat to reset, and during the reset process, the connecting rod will drive the protective door to close, effectively isolating the stamping area and the operator, avoiding the operator from accidentally touching the trigger device during the stamping process to cause the equipment to start suddenly, ensuring that the operator operates in a safe position, and the protective door is closed by mechanical linkage, which can better improve work efficiency, reduce the time and cost of manual intervention, and also reduce the labor intensity of the operator;

[0018] Secondly, when the lower mold needs to be replaced, it is only necessary to rotate the rotating screw so that the pressure limit rod on the outer wall of the rotating screw's circumference is far away from the groove, and then move the two moving rods close to each other so that the blocks on their respective side walls are away from the groove, and then the lower mold can be disassembled and replaced. The same is true when replacing the upper mold. It can better reduce the number of bolts used and effectively improve the efficiency of mold replacement. After the stamping is completed, the cylinder 2 can be used to drive the material block to push the workpiece out, which is convenient for personnel to collect and effectively improve the processing efficiency of personnel.
