[0002] A stamping die is a special process equipment for processing metals into parts (or semi-finished products) in cold stamping processing, called a cold stamping die (commonly known as a cold punching die). Stamping is a pressure processing method in which, at room temperature, a die installed on a press applies pressure to a material to cause separation or plastic deformation, thereby obtaining the required parts.

[0003] Traditional stamping equipment often faces many problems when replacing dies. The installation and disassembly of dies require a large amount of manual operations, which not only have a high labor intensity but also low efficiency. Workers need to use various tools for complex operations, such as removing screws and adjusting positioning. This process is prone to human errors, affecting the installation accuracy of the die and the quality of stamping products.

[0021] The distance of the extension rod 7 can be adjusted by loosening the reverse nut 11 and the forward nut 12. After adjustment, tighten the reverse nut 11 and the forward nut 12. At the same time, the distance between the extension rods 7 can also be adjusted inside the straight slot 15 to adapt to the widths of different molds. A rubber pad 10 is fixedly connected to the other side of the corner plate 9. When squeezing and fixing the four corners of the mold, the rubber pad 10 increases the friction force. And the outside of the moving plate is set to a matte state, which is convenient for the reverse nut 11 and the forward nut 12 to fit tightly together.

[0022] A hinge 18 is fixedly connected to the outside of the chassis 1. One side of the hinge 18 is fixedly connected to a side plate 19. A fixed block 20 is fixedly connected to the inner wall of the side plate 19. An L-shaped rod 21 is slidably connected inside the fixed block 20. A compression spring 22 is arranged outside the L-shaped rod 21. A limit ring 23 is fixedly connected to the outside of the L-shaped rod 21. A circular sleeve 24 is fixedly connected to the inner wall of the chassis 1. The L-shaped rod 21 is inserted into the circular sleeve 24.

[0023] The hinge 18 enables the chassis 1 to be folded with the side plate 19. When the L-shaped rod 21 is pulled outwards, when the compression spring 22 is squeezed and contracted, the L-shaped rod 21 disengages from the inside of the circular sleeve 24, making the side plate 19 not fixed, and folding the side plate 19. When folding and flipping, it is convenient for personnel to repair the equipment inside the chassis 1 to improve the repair space and facilitate personnel operation.

[0024] A side groove 25 is opened at the top of the workbench 4. A moving frame 26 is slidably connected inside the side groove 25. A hydraulic mechanism 27 is fixedly connected to the outside of the moving frame 26. A threaded column 28 is threadedly connected inside the hydraulic mechanism 27. A punching plate 29 is fixedly connected to the bottom of the threaded column 28.

[0025] By connecting the hydraulic mechanism 27 and the punching plate 29 through the threaded column 28, it is convenient to quickly replace different punching plates 29.

[0026] Ventilation grooves 30 are opened on the outside of the side plate 19. A ventilation hood 31 is fixedly connected to the outside of the side plate 19.

[0027] By keeping the ventilation grooves 30, the operating equipment inside the chassis 1 can be ventilated and cooled. Due to the sloping shape of the ventilation hood 31, dust is prevented from entering.

[0028] A wheel column 32 is fixedly connected to the bottom of the chassis 1. A universal wheel 33 is fixedly connected to the bottom of the wheel column 32.

[0029] The universal wheel 33 increases the overall flexible mobility.

[0030] A mounting bolt 34 is fixedly connected to the top of the mounting plate 2. The mounting bolt 34 penetrates through the mounting plate 2 and extends to the outside of the mounting plate 2. The mounting bolt 34 is threadedly connected to the chassis 1.

[0031] The mounting plate 2 is fixed by the mounting bolt 34, avoiding welding and preventing it from being unable to be quickly replaced during replacement.

[0032] The working principle of the stamping die for the new sheet metal chassis 1 provided by the present utility model is as follows: A fixed plate 5 is installed on the top of the workbench 4, and a through slot 6 is opened on the outside of the fixed plate 5 to facilitate the sliding of the extension rod 7 inside the through slot 6. A pull slot 13 is opened on the top of the workbench 4, and a pull plate 14 is slidably connected inside the pull slot 13. When the pull plate 14 moves, it is restricted. The reverse nut 11 and the forward nut 12 are manually rotated by threading on the extension rod 7. When rotating, the pull plate 14 between the reverse nut 11 and the forward nut 12 is fixed or loosened. And when a straight slot 15 is opened on the outside of the pull plate 14, it is convenient to shorten or extend the distance between the extension rods 7 when the reverse nut 11 and the forward nut 12 are loosened, facilitating the fixation of dies with different widths. A square plate 16 is installed on the top of the pull plate 14, and a pull rod 17 is installed on one side of the square plate 16. When the pull rod 17 is pulled, the pull plate 14 slides inside the pull slot 13. One end of the extension rod 7 is installed with a corner plate 9, and when loosened, the corner plate 9 stabilizes the four corners of the die.

[0033] Compared with the related technology, the stamping die for the new sheet metal chassis 1 provided by the present utility model has the following

[0034] Beneficial effects:

[0035] The present utility model provides a stamping die for a new sheet metal chassis 1. By installing a stretching mechanism on the chassis 1, when the stretching mechanism cooperates with the fixed plate 5, the extension rod 7, the compression spring 8, the corner plate 9, the reverse nut 11, the forward nut 12, and the pull plate 14, the stroke of the extension rod 7 can be changed when the reverse nut 11 and the forward nut 12 on the extension rod 7 are turned by a person. When the reverse nut 11 and the forward nut 12 are tightly fitted, the pull plate 14 can be clamped. By a person pulling the pull plate 14, the compression spring 8 on the extension rod 7 is squeezed. When loosened, the corner plate 9 fixes the four corners of the die, realizing the shortening of the die replacement time, and being able to reduce the labor cost and the equipment idle cost.
