Detailed Implementation
[0033] 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.
[0034] Reference Figures 1 to 3This utility model provides an embodiment of a punching device with a protective structure, comprising a base 1, two fixed frames 2 fixedly connected to the top of the base 1, the base 1 supporting and fixing the position of the two fixed frames 2, and the fixed frames 2 fixing the end position of the entire telescopic component. Movable frames 3 are slidably connected to the inner walls of both fixed frames 2. The outer surface of the movable frames 3 is square, while the inner wall of the fixed frames 2 is a larger square, allowing the movable frames 3 to slide freely on the inner walls of the fixed frames 2. Sliding frames 4 are slidably connected to the inner walls of both movable frames 3. The outer surface of the sliding frames 4 is square, while the inner wall of the movable frames 3 is a larger square, allowing the sliding frames 4 to slide freely on the inner walls of the movable frames 3. A baffle 6 is fixedly connected to the bottom of a protective cover 5, protecting the front end of the telescopic component for more comprehensive protection.
[0035] A connecting plate 7 is fixedly connected to the outside of the movable frame 3. The movable frame 3 is fixed in position with respect to the connecting plate 7, and the position of the movable frame 3 changes as the position of the connecting plate 7 changes. Two positioning plates 8 are slidably connected to the inner wall of the fixed frame 2. The fixed frame 2 limits the sliding position of the two positioning plates 8 and prevents them from disengaging at the sliding ends. A pulley 2 10 is rotatably connected to the adjacent side of the two positioning plates 8, and the positioning plates 8 fix the rotational position of the pulley 2 10. A pulley 1 9 is rotatably connected to the adjacent side of the two positioning plates 8 away from the pulley 2 10, and the positioning plates 8 fix the rotational position of the pulley 1 9. A belt 11 is sleeved on the outside of the pulley 1 9, and the end of the belt 11 away from the pulley 1 9 is sleeved on the outside of the pulley 2 10 (as shown in the attached figure). Figure 3 The belt 11 connects pulley 9 and pulley 10, and the rotation of pulley 9 causes pulley 10 to rotate. A sliding block 13 is slidably connected to the outside of the belt 11; the position of the sliding block 13 causes the belt 11 to rotate. A connecting plate 7 is fixedly connected to the bottom of the sliding block 13; the position of the connecting plate 7 causes the sliding block 13 to change position.
[0036] A protective cover 5 is fixedly connected to the top of the sliding frame 4. The position of the protective cover 5 changes, causing the position of the sliding frame 4 to change. Fixing blocks 12 are fixedly connected to the inner walls of both fixed frames 2, providing positional stability for the fixed frames 2. The belt 11 is externally slidably connected to the inner wall of the fixing blocks 12 (as shown in the attached diagram). Figure 3 The fixed block 12 has a limiting effect on the movement position of the belt 11. The fixed block 12 is fixed in position, and the belt 11 slides under the drive of the sliding block 13. At this time, the belt 11 slides along with the belt. After the belt 11 slides to a certain position, the fixed block 12 has a limiting effect, so that the belt 11 stops sliding. At this time, the sliding of the belt 11 outside the pulley 9 and pulley 10 stops together.
[0037] ReferenceFigure 6 Both movable frames 3 are fixedly connected to locking components that lock the position of the protective cover 5. The movable frames 3 limit the position of the locking components. The locking components include a rotating block 22, one end of which is rotatably connected to the outside of the movable frame 3. After the position of the protective cover 5 is determined, the rotating block 22 is moved. The other end of the rotating block 22 is rotatably connected to a locking rod 23. The rotation of the rotating block 22 causes the locking rod 23 to change position. Both sliding frames 4 have multiple slots inside, which are used to lock the position in the locking components. The locking rod 23 is slidably connected to the inner wall of the slot. During the position change, the connection end of the locking rod 23 with the rotating block 22 will rotate slightly to accommodate the engagement of the locking rod 23 with the slot.
[0038] Reference Figure 2 , Figure 4 and Figure 5 A support frame 14 (as shown in the attached figure) is fixedly connected to the top of the base 1. Figure 2 The base 1 supports and fixes the position of the support frame 14. A cylinder 15 is mounted on the bottom of the support frame 14, supporting and fixing the cylinder 15 in its mounting position. A fixing box 17 is fixedly connected to the outside of the cylinder 15; changes in the position of the cylinder 15 drive end cause changes in the position of the fixing box 17. A sliding box 18 is slidably connected to the inner wall of the fixing box 17; changes in the position of the fixing box 17 cause changes in the position of the sliding box 18. Multiple springs 19 (as shown in the attached diagram) are fixedly connected to the inner wall of the fixing box 17. Figure 4 The positional change of the fixed box 17 causes the position of multiple springs 19 to change as well, and the multiple springs 19 help to adhere to the component during the movement. The bottom of the multiple springs 19 is fixedly connected to the inner wall of the sliding box 18, and the sliding box 18 helps to fix the other end of the springs 19 in position.
[0039] A pressure plate 20 is slidably connected to the drive end of cylinder 15. When cylinder 15 is started, the position change of the drive end of cylinder 15 causes the pressure plate 20 to change position. A punching structure 21 (as shown in the attached figure) is fixedly connected to the drive end of cylinder 15. Figure 4 The cylinder 15 drives the punching structure 21 to approach the workpiece and process it. The bottom of the sliding box 18 is fixedly connected to the top of the pressure plate 20. When the pressure plate 20 touches the workpiece, it exerts a reverse force on the sliding box 18, causing the sliding box 18 to slide. Multiple telescopic columns 16 are fixedly connected to the bottom of the support frame 14, providing support and fixing the position of the telescopic columns 16. The other ends of the multiple telescopic columns 16 are fixedly connected to the top of the pressure plate 20 (as shown in the attached diagram). Figure 5 Multiple telescopic columns 16 follow the positional changes of the pressure plate 20, thus ensuring that the pressure plate 20 remains stable during the positional changes.
[0040] Working principle: When not in operation, pulling the protective cover 5 causes the sliding frame 4 to slide, which in turn causes the connecting plate 7 to move. This movement of the connecting plate 7 causes the sliding block 13 to slide outside the belt 11. The sliding block 13 causes the belt 11 to rotate around pulley 9 and pulley 10. When pulled to a certain position, pulley 9 and pulley 10 move, causing the two positioning plates 8 to slide on the inner wall of the fixed frame 2. This causes the protective cover 5 to move laterally backward. This is useful for changing the object to be cut or checking the cutting status of the stopped cutting device. The protective cover 5 effectively prevents operators from accidentally touching moving parts or sharp blades while the equipment is running. The protective cover 5 can also block metal fragments, grease, and other splashes, protecting operators from injury and reducing workplace contamination.
[0041] When cylinder 15 is activated, the position change of the drive end of cylinder 15 causes the pressure plate 20 to change position. When the bottom of the pressure plate 20 touches the object to be punched, the object exerts a reverse force on the pressure plate 20, causing the pressure plate 20 to rise in the reverse direction. This causes the sliding box 18 to rise in the reverse direction, thereby compressing and deforming multiple springs 19. This allows multiple springs 19 to have a restoring force, causing the sliding box 18 to move down and drive the pressure plate 20 to press the object. This ensures that the pressure plate 20 is in close contact with the object, which can ensure that the object remains stable during the punching process and reduce cutting deviations or failures caused by object movement. By pre-pressing to determine the position, the adjustment and alignment time can be reduced, and production efficiency can be improved.
[0042] 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.
