[0002] Mechanical engineering is a discipline that studies force, motion, and their interactions. It involves the laws of motion, mechanical principles, and applied technologies of objects from the macroscopic to the microscopic level. In the machining process, a punch press is used to place the material in the mold by means of a die and a pressure plate. The punch then applies high pressure to achieve the desired shape and size.
[0003] During the punching process, traditional punch presses lack protective structures to isolate operators from the moving parts of the machine. Operators' hands or body parts may accidentally enter the work area, causing injury, especially when the punch is pressed down rapidly, which is extremely dangerous and reduces the operational safety of the equipment. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides a mechanical shifting safety protection device, which aims to improve the lack of protective structure in the existing traditional punch press to isolate the operator from the moving parts of the machine, and prevent the operator's hands or body parts from accidentally entering the work area and causing injury.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A mechanical shifting safety protection device includes a fixed frame, an adjusting frame fixedly connected to the upper part of the fixed frame, and a stamping protection component provided on the upper part of the adjusting frame;
[0007] The stamping protection assembly includes a cylinder, which is fixedly connected to the upper part of the adjusting frame. A mounting block is fixedly connected to the output end of the cylinder. A rack plate is fixedly connected to the outside of the mounting block. A rotating rod is rotatably connected inside the adjusting frame. A gear is fixedly connected to the outside of the rotating rod, and the gear meshes with the rack plate.

A lever is fixedly connected to the left side of the rotating block. A protective assembly is provided outside the lever. An upper die base is fixedly connected to the bottom of the rack plate. A punch is installed at the lower part of the upper die base.
[0008] Furthermore, the protective component includes a protective shell disposed outside the lever, and protrusions are fixedly connected to both sides inside the protective shell.
[0009] Furthermore, the adjusting frame has a through hole inside, and the rack plate is slidably connected inside the through hole.
[0010] Furthermore, a telescopic rod is fixedly connected to the lower part of the adjusting frame, and a connecting block is fixedly connected to the top of the telescopic rod. The connecting block is externally fixedly connected to the outside of the upper mold base.

[0014] Furthermore, mounting holes are provided on all four sides of the interior of the fixing frame.
[0015] This utility model has the following beneficial effects:
[0016] 1.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figures 1-5 The present invention provides an embodiment of a mechanical shifting safety protection device, including a fixed frame 1, an adjusting frame 3 fixedly connected to the upper part of the fixed frame 1, and a stamping protection component provided on the upper part of the adjusting frame 3. The stamping protection component can provide protection during stamping. The fixed frame 1 has mounting holes 2 on all four sides inside, which facilitates fixing the fixed frame 1.
[0027] The stamping protection assembly includes a cylinder 20, which is fixedly connected to the upper part of the adjusting frame 3. A mounting block 4 is fixedly connected to the output end of the cylinder 20. A rack plate 5 is fixedly connected to the outside of the mounting block 4. A rotating rod 8 is rotatably connected inside the adjusting frame 3. A gear 6 is fixedly connected to the outside of the rotating rod 8, meshing with the rack plate 5. A rotating block 11 is fixedly connected to the front side of the rotating rod 8. Limit rods 13 are fixedly connected to the right side of each rotating block 11. A lever 12 is fixedly connected to the left side of the rotating block 11. A protective assembly is provided on the outside of the lever 12. An upper die base 9 is fixedly connected to the bottom of the rack plate 5. A punch 10 is installed at the lower part of the mold base 9. A through hole 7 is opened inside the adjusting frame 3. The rack plate 5 is slidably connected inside the through hole 7. The through hole 7 facilitates the movement of the rack plate 5. A telescopic rod 15 is fixedly connected to the lower part of the adjusting frame 3. A connecting block 16 is fixedly connected to the top of the telescopic rod 15. The connecting block 16 is fixedly connected to the outside of the upper mold base 9. The telescopic rod 15 assists in the movement of the upper mold base 9. An annular groove 14 is opened on the outside of the adjusting frame 3. Two limiting rods 13 are slidably connected inside the two annular grooves 14. The annular grooves 14 facilitate the movement of the limiting rods 13.
[0028] Specifically, during the stamping process, cylinder 20 drives the mounting block 4, which is fixed to the output belt, to move downward. Cylinder 20 transmits this movement to rack plate 5 by controlling the vertical movement of mounting block 4. During the downward movement of rack plate 5, through its meshing with gear 6, the downward movement of rack plate 5 drives upper die base 9 downward, ultimately driving the vertical movement of punch 10. Specifically, when rack plate 5 moves downward, its gear 6 rotates through meshing with rack plate 5. The rotation of gear 6 further drives the rotation of rotating rod 8 connected to it. Rotating rod 8 transmits power from gear 6 to rotating block 11. Rotating block 11 continues to rotate, driving lever 12 to rotate. Through the rotation of lever 12, the operator can be effectively isolated from the moving parts of the punch press, preventing the risk of the operator accidentally entering the working area of the equipment. When the punch 10 of the punch press is pressed down rapidly, there is a great danger. The rotation of lever 12 can effectively physically isolate the dangerous area from the operating area, thereby improving the safety of equipment operation.
[0029] Reference Figures 2-4 The protective component includes a protective shell 17, which is disposed outside the lever 12. Both sides of the inner side of the protective shell 17 are fixedly connected to protrusions 18. Both sides of the outer side of the lever 12 are provided with sliding grooves 19. The two protrusions 18 are slidably connected inside the two sliding grooves 19. The protective shell 17 is made of rubber, which has good flexibility and elasticity. The protective shell 17 can play an effective cushioning role, preventing the operator from directly contacting the moving parts of the equipment and reducing the risk of injury due to improper operation or equipment failure.
[0030] Specifically, during the installation of the protective shell 17 on the outside of the lever 12, the protrusions 18 fixed on both sides inside the protective shell 17 must first be aligned with the sliding grooves 19 on both sides outside the lever 12. Then, the protrusions 18 are inserted into the sliding grooves 19. At this time, the cooperation between the protrusions 18 and the sliding grooves 19 can effectively fix the protective shell 17 on the outside of the lever 12, preventing the protective shell 17 from loosening or falling off during equipment operation. Due to the design of the protrusions 18 and the sliding grooves 19, the protective shell 17 can be firmly fitted on the outside of the lever 12 and remain stable during normal operation. After the protrusions 18 and the sliding grooves 19 are fully aligned, the protective shell 17 is moved so that it is completely fitted on the outside of the lever 12. During this process, a tight fit is formed between the inner and outer walls of the protective shell 17 and the lever 12. The protective shell 17 firmly wraps around the lever 12, which can effectively reduce wear or damage caused by impact force, extend the service life of the equipment, and reduce maintenance costs.
[0031] Working principle: During stamping, the cylinder 20 moves the mounting block 4 with the output belt fixed downwards. The downward movement of the mounting block 4 moves the rack plate 5 fixed externally downwards, which in turn moves the upper die base 9 fixed at the bottom. The movement of the upper die base 9 moves the punch 10 fixed at the bottom. At the same time, as the rack plate 5 moves downwards, it drives the externally meshing gear 6 to rotate. When the gear 6 rotates, it drives the internally fixed rotating rod 8 to rotate. The rotation of the rotating rod 8 drives the externally fixed rotating block 11 to rotate. The rotation of the rotating block 11 drives the externally fixed lever 12 to rotate. The rotation of the lever 12 can isolate the operator from the moving parts of the machine, preventing the operator's hands or body parts from accidentally entering the work area, thereby improving the safety of equipment operation.
[0032] When installing the protective shell 17 on the outside of the lever 12, firstly, align the protrusions 18 fixed on both sides inside the protective shell 17 with the sliding grooves 19 opened on both sides outside the lever 12. Then, insert the protrusions 18 into the inside of the sliding grooves 19. Next, move the protective shell 17 so that it fits over the outside of the lever 12. This allows the protective shell 17 to be installed on the outside of the lever 12, which can buffer the force generated by the impact of the lever 12, thereby reducing wear or damage caused by the collision. This can effectively extend the service life of the equipment and reduce maintenance costs.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
