Technical Field

[0001] The utility model relates to the technical field of stamping, in particular to a steel plate stamping machine with air shock absorption. Background Technique

[0002] A punching press is a stamping press. Stamping production mainly targets sheet materials. Through molds, blanking, punching, forming, drawing, trimming, etc. can be achieved, and it is widely used in various fields. For example, the accessories such as the switch sockets, cups, and cupboards we use can all be produced by the punching press through molds. Due to the advantages of saving materials and energy, high efficiency, low technical requirements for operators, and the ability to produce products that cannot be achieved by mechanical processing through various mold applications compared with traditional mechanical processing, stamping technology is becoming more and more widely used.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figures 1 to 8 , and the above technical solutions of the present utility model will be described in detail through the following embodiments:

[0032] A steel plate stamping machine with air shock absorption includes: a stamping table 1; a steel plate body 2 is arranged on the top of the stamping table 1, a cross beam 3 is arranged on the top of the steel plate body 2, guide rails 4 are fixedly connected to both sides of the cross beam 3, the bottom ends of the guide rails 4 are fixedly connected to the stamping table 1, a stamping plate 5 is arranged between the steel plate body 2 and the cross beam 3, lifting blocks 6 are fixedly connected to both sides of the stamping plate 5, buffer rods 7 are fixedly connected to the bottom ends of the lifting blocks 6, and the bottom ends of the buffer rods 7 penetrate through the stamping table 1 and extend to the outside of the stamping table 1; buffer mechanisms 8 for relieving the force of the device through air are arranged at the bottom ends of the buffer rods 7; rotating mechanisms 9 for positioning and clamping the steel plate body 2 are arranged on both sides of the steel plate body 2. The user places the steel plate body 2 on the stamping table 1, then positions and clamps the steel plate body 2 through the rotating mechanism 9, and then controls the stamping plate 5 to move downward. While the stamping plate 5 moves downward, it drives the lifting block 6. While the lifting block 6 slides inside the guide rail 4, it drives the buffer rod 7. The buffer rod 7 performs air shock absorption through the buffer mechanism 8, so as to achieve the purpose of buffering and shock absorption of the device.

[0033] As Figures 2 to 4 shown, the buffer mechanism 8 includes: piston 10 is fixedly connected to the bottom end of the buffer rod 7, sealing rings 11 are fixedly connected to the outer surface of the piston 10, buffer cylinders 12 adapted to the outer surface of the sealing rings 11 are sleeved on the outer surface of the sealing rings 11, air storage cylinders 13 are arranged on the outside of the buffer cylinders 12, and the buffer cylinders 12 and the air storage cylinders 13 are fixedly connected to the stamping table 1; tiny exhaust holes 14 are opened on both sides of the bottom of the buffer cylinder 12, through holes 15 are opened on both sides of the top of the air storage cylinder 13, and the diameter of the through hole 15 is larger than that of the exhaust hole 14; a one-way mechanism 16 for quickly returning the air inside the air storage cylinder 13 to the inside of the buffer cylinder 12 is arranged at the center of the bottom of the air storage cylinder 13. While the buffer rod 7 moves downward, it drives the piston 10, and the one-way mechanism 16 seals the bottom of the buffer cylinder 12. The piston 10 drives the sealing ring 11 to squeeze the air inside the buffer cylinder 12. Through the resistance generated by the squeezed air, the buffer rod 7 is buffered. At the same time, the air squeezed inside the buffer cylinder 12 will slowly be discharged into the air storage cylinder 13 through the exhaust hole 14, and the air inside the air storage cylinder 13 is discharged through the through hole 15.

[0034] As Figure 4As shown, the one-way mechanism 16 includes: a fixing rod 17 is fixedly connected to the center of the bottom of the air storage cylinder 13. A return hole 18 is provided in the buffer cylinder 12 near the fixing rod 17. An elastic disc 19 is sleeved on the outer surface of the fixing rod 17, and the elastic disc 19 is matched with the return hole 18. A limiting block 20 is fixedly connected to the top of the fixing rod 17. When the stamping plate 5 rises, the buffer rod 7 is pulled through the lifting block 6. The buffer rod 7 drives the piston 10 and the sealing ring 11, so that a negative pressure is generated inside the buffer cylinder 12. The air pushes the elastic disc 19, so that the outside air enters through the through hole 15 on the air storage cylinder 13 and then quickly returns to the inside of the buffer cylinder 12 through the return hole 18 at the bottom of the buffer cylinder 12, so that the stamping plate 5 can quickly rise and reset.

[0035] As Figure 1 and Figure 2 As shown, springs 21 are arranged between the lifting block 6 and the stamping table 1. The springs 21 are respectively sleeved on the outer surface of the buffer rod 7. When the lifting block 6 moves downward, the springs 21 are compressed. The springs 21 buffer and relieve the force on the stamping plate 5 through their own elastic force, so that the device is shock-absorbed by the cooperation of air shock-absorption and spring 21 shock-absorption, which not only improves the shock-absorption effect, but also solves the problem that after the springs 21 are squeezed and released multiple times, the resilience of the springs 21 themselves will decrease, resulting in a reduction in the buffer effect.

[0036] As Figure 6 and Figure 7 As shown, the rotating mechanism 9 includes: clamping blocks 22 are arranged on both sides of the steel plate body 2. The clamping blocks 22 are all slidably connected to the stamping table 1. The bottoms of the clamping blocks 22 are fixedly connected with first rotating shafts 23. Link rods 24 are rotatably connected to the outer surfaces of the first rotating shafts 23. The ends of the link rods 24 far from the first rotating shafts 23 are rotatably connected with second rotating shafts 25. The bottoms of the second rotating shafts 25 are fixedly connected with circular plates 26. A third rotating shaft 27 is rotatably connected inside the circular plate 26. The bottom end of the third rotating shaft 27 is fixedly connected with a protective box 28. The protective box 28 is fixedly connected to the stamping table 1. A locking mechanism 29 for controlling the self-rotation of the circular plate 26 is arranged at the bottom of the circular plate 26. The user controls the circular plate 26 to rotate around the first rotating shaft 23 through the locking mechanism 29. The circular plate 26 drives the second rotating shaft 25 to make a circumferential movement. While the second rotating shaft 25 makes a circumferential movement, it pulls the link rod 24. The link rod 24 pulls the first rotating shaft 23. The first rotating shaft 23 drives the clamping block 22, and the two clamping blocks 22 move towards the steel plate body 2 inside the stamping table 1, so as to position and clamp the steel plate body 2.

[0037] As Figure 2 and Figure 6As shown in the figure, the locking mechanism 29 includes: a connecting sleeve 30 is fixedly connected to the bottom of the circular plate 26, and a worm gear 31 is fixedly connected to the bottom of the connecting sleeve 30; a worm 32 is engaged with one side of the worm gear 31, one end of the worm 32 is rotatably connected to the protective box 28, the other end of the worm 32 penetrates through the protective box 28 and extends to the handle 33, the handle 33 is fixedly connected to the worm 32, by rotating the handle 33, the handle 33 drives the worm 32, the worm 32 drives the worm gear 31, and the worm gear 31 drives the circular plate 26 to rotate through the connecting sleeve 30.

[0038] As Figure 7 shown, damping pads 34 are arranged near the clamping blocks 22 close to the steel plate body 2, and the damping pads 34 are fixedly connected to the clamping blocks 22 respectively, which improves the stability of the clamping blocks 22 clamping the steel plate body 2 and avoids loosening.

[0039] As Figure 5 and Figure 7 shown, two limiting slide bars 35 are fixedly connected near the clamping blocks 22 on the punching table 1, and sliding grooves 36 adapted to the limiting slide bars 35 are formed near the clamping blocks 22, which can limit the clamping blocks 22 and enable the clamping blocks 22 to slide horizontally flexibly inside the punching table 1.

[0040] As Figure 1 and Figure 2 shown, two hydraulic cylinders 37 are fixedly connected inside the cross beam 3, and the telescopic ends of the hydraulic cylinders 37 are fixedly connected to the punching plate 5. The purpose of controlling the punching plate 5 to lift and punch can be achieved by controlling the telescopic ends of the hydraulic cylinders 37 to extend and retract.

[0041] As Figure 8 shown, a punching tool 38 adapted thereto is arranged inside the punching plate 5, locking knobs 39 are arranged on both sides of the punching plate 5, one ends of the locking knobs 39 penetrate through the punching plate 5 and extend to the inside of the punching tool 38, and the locking knobs 39 are threadedly connected to the punching plate 5. The user can replace the punching tool 38 by rotating the locking knobs 39, which improves the practicability.

[0042] Working principle: The user controls the telescopic end of the hydraulic cylinder 37 to expand and contract to achieve the purpose of controlling the lifting and stamping of the stamping plate 5. When the stamping plate 5 moves downward, the lifting block 6 is driven while the stamping plate 5 moves downward. The lifting block 6 drives the buffer rod 7 while sliding inside the guide rail 4. The buffer rod 7 drives the piston 10 while moving downward. The piston 10 drives the sealing ring 11 to squeeze the air inside the buffer cylinder 12. Through the resistance generated by the squeezed air, the buffer rod 7 is buffered. At the same time, the air squeezed inside the buffer cylinder 12 will slowly be discharged into the inside of the air storage cylinder 13 through the exhaust hole 14. The air inside the air storage cylinder 13 is discharged through the through hole 15. At the same time, the lifting block 6 squeezes the spring 21 while moving downward. The spring 21 buffers and relieves the force on the stamping plate 5 through its own elastic force, enabling the device to be shock-absorbed by the mutual cooperation and assistance of air shock absorption and spring shock absorption. This not only improves the shock-absorbing effect but also solves the problem that after the spring is squeezed and released multiple times, the resilience of the spring itself will decrease, resulting in a reduction in the buffer effect. When the stamping plate 5 rises, the buffer rod 7 is pulled by the lifting block 6. The buffer rod 7 drives the piston 10 and the sealing ring 11, causing a negative pressure inside the buffer cylinder 12. The air pushes the elastic disc 19, enabling the outside air to enter through the through hole 15 on the air storage cylinder 13 and quickly flow back into the inside of the buffer cylinder 12 through the return hole 18 at the bottom of the buffer cylinder 12, thereby enabling the stamping plate 5 to quickly rise and reset.

[0043] Rotate the turning handle 33. The turning handle 33 drives the worm 32. The worm 32 drives the worm gear 31. The worm gear 31 drives the circular plate 26 to rotate around the first rotating shaft 23 through the connecting sleeve 30. The circular plate 26 drives the second rotating shaft 25 to make a circumferential movement. While the second rotating shaft 25 makes a circumferential movement, the linkage rod 24 is pulled. The linkage rod 24 pulls the first rotating shaft 23. The first rotating shaft 23 drives the clamping block 22. The two clamping blocks 22 move towards the steel plate body 2 inside the stamping table 1, thereby positioning and clamping the steel plate body 2. The steel plate body 2 to be stamped can be positioned and clamped, making the steel plate body 2 firmly fixed in the middle of the stamping table 1, avoiding the situation where the steel plate body 2 is displaced during stamping, resulting in poor product accuracy or scrapping.

[0044] Finally, it should be noted that: The above embodiments are only used to illustrate the technical solutions of the present invention, not to limit it; Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: They can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; And these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
