[0002] Automotive parts manufacturing refers to the process of processing raw materials into parts or components that meet specific specifications and functional requirements according to design requirements. This process involves multiple steps and complex technological flows, including blank preparation, cutting, heat treatment, and surface treatment.

[0003] The prior art discloses a protective device for an automotive parts stamping machine, application number CN202322381934.1, belonging to the field of automotive parts processing technology. It includes a worktable, with a base fixedly mounted to the center of the upper surface of the worktable by bolts. Fixed frames are also fixedly mounted on both sides of the upper surface of the worktable, and a fixed plate is fixedly mounted between the two fixed frames by bolts. A protective mechanism for parts stamping is mounted on the fixed plate. In this automotive parts stamping machine protective device, a cylinder output pushes a lifting column downwards, which in turn provides elastic support to the protective box via a compression spring using a fixed ring as a support point. Driven by the lifting column, the protective box and the stamping plate move downwards synchronously. When the protective box is in contact with the base, the fixed ring continues to compress the spring, causing the lifting column to push the stamping plate downwards inside the protective box, thus allowing the stamping plate to stamp the automotive parts inside the protective box.

[0027] The stamping device 1 includes a metal vertical rod 11, an electric push rod 12, a protective shell 13, a connecting assembly 14, a connecting plate 15, and a limiting plate 16. The limiting plate 16 is located at the upper end of the stamping device 1 and is threadedly connected to the upper end of the metal vertical rod 11. The connecting plate 15 is fixedly connected to the bottom surface of the metal vertical rod 11. The metal plate 4 is movably connected to the surface of the metal vertical rod 11 and is fixedly connected to the bottom surface of the electric push rod 12. The piston rod inside the electric push rod 12 pushes the limiting plate 16 to move the metal vertical rod 11 up and down, which facilitates the adjustment of the position of the protective shell 13. The connecting plate 15 is threadedly connected to the upper end of the protective shell 13. The limiting plate 16 is fixedly connected to the top surface of the electric push rod 12. The connecting plate 15 is installed at the lower end of the connecting assembly 14.

[0028] The connecting assembly 14 includes an electric push rod 141, a stamping plate 142, a metal housing 143, a connecting frame 144, a threaded rod 145, a coil spring 146, and a connector 147. The stamping plate 142 is located at the lower end of the connecting assembly 14 and is movably connected to the lower end of the internal piston rod of the electric push rod 141. The metal plate 4 is installed at the lower end of the electric push rod 141. The electric push rod 141 is connected to the middle position of the connecting plate 15. The internal piston rod of the electric push rod 141 is connected to the connecting frame 147. The surface of plate 15 slides, allowing the internal piston rod of electric push rod 141 to push stamping plate 142 downward, thus enabling stamping plate 142 to perform stamping operations. Connector 147 is inserted into the upper end of stamping plate 142. Stamping plate 142 is movably connected to the inner wall surface of protective housing 13. Stamping plate 142 is located below connecting plate 15. Connecting plate 15 is slidably connected to the lower end surface of the internal piston rod of electric push rod 141. The internal piston rod of electric push rod 141 is located in the middle of connecting plate 15. The piston rod inside the electric push rod 141 moves the stamping plate 142 downwards, allowing for stamping operations. The metal housing 143 is fixedly connected to the top surface of the stamping plate 142. A threaded rod 145 is inserted into the right end of the metal housing 143 and into the rear end of a connector 147. The connector 147 is fixedly connected to the front of the coil spring 146, allowing the threaded rod 145 to insert into the rear end of the connector 147. Simultaneously, the threaded rod 145 inserts into... The lower end of the connecting frame 144 facilitates the pulling out of the plug-in part 147. The plug-in threaded rod 145 is inserted into the lower end of the connecting frame 144. The helical spring 146 is fixedly connected to the back of the metal shell 143. There are two electric push rods 12, which are distributed left and right. An electric push rod 141 is set between the two electric push rods 12.
