Description

Technical Field

[0001] This invention relates to the field of stamping equipment, specifically to a punching device for a fine denier spinneret with an adjustable structure. Background Technology

[0002] Punching, as a cold forming process in stamping, mainly relies on the cooperation of a forming punch and a matching die to complete the punching operation. Among these processes, punching equipment is frequently used to process irregular holes in fine-denier spinnerets.

[0003] However, when existing punching equipment punches irregular holes on spinnerets, the cross punches required for punching these irregular holes are very thin and therefore prone to breakage during processing. Since the equipment lacks an automatic detection and alarm mechanism when the punch breaks, workers cannot detect the breakage in time. Furthermore, each time the punch breaks, workers need to manually replace it, which is quite cumbersome and inconvenient to use. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing a fine denier irregular-shaped spinneret punching device with an adjustable structure.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a punching device for a fine denier spinneret with an adjustable structure, comprising a punching table, a platform fixedly mounted on the upper rear part of the punching table, a second servo cylinder throughly mounted on the upper end of the platform, a punching frame fixedly mounted on the output end of the second servo cylinder, a T-shaped slide rail fixedly mounted between the two ends of the punching frame, a needle seat slidably mounted on the outer surface of the T-shaped slide rail, a punching pin provided at the front end of the needle seat, and a slide rail connected to the inner side of the punching frame. A reset rod is elastically mounted through the end of the slide block. A slide frame is slidably mounted on the upper end of the slide block. A needle shifting frame is rotatably mounted between the slide frame and the reset rod. A needle shifting claw is rotatably mounted on the end of the slide frame. Multiple needle shifting oblique blocks extend linearly from the upper end of the needle holder. An infrared photoelectric sensor is arranged behind the stamping frame. The infrared photoelectric sensor is connected to the second servo push cylinder through a controller. A pressure rod is arranged above the reset rod. The pressure rod is fixed to the table plate. A clamping member is arranged at the front of the upper end of the punching table.

[0006] Preferably, two guide rods are symmetrically fixedly installed on the upper end of the stamping frame, the platform is slidably installed on the outer surface of the guide rods, a fixing frame is fixedly installed on the outer surface of the infrared photoelectric sensor, and the lower end of the fixing frame is fixed to the punching platform.

[0007] Preferably, a reset spring is wound around the outside of the reset rod, and the two ends of the reset spring are fixed to the upper end of the reset rod and the upper end of the slide, respectively. A top claw bracket is fitted to the side of the needle shifting claw, and the end of the top claw bracket is fixed to the slide.

[0008] Preferably, a connecting frame is fixedly installed at the rear end of the slide block, and the end of the connecting frame is fixed to the stamping frame. A bending frame is fixedly installed at the lower end of the connecting frame. Two guide posts are slidably installed through the end of the bending frame. A pin fixing block is fixedly installed between the ends of the two guide posts. The pin fixing block is pressed against the rear end of the pin seat. A tensioning spring is wound around the outside of the guide posts. The two ends of the tensioning spring are fixed to the bending frame and the pin fixing block, respectively. Multiple sets of triangular teeth are fixedly installed in a linear array at the rear end of the pin seat. The triangular holes on the pin fixing block engage with one set of triangular teeth. Each set of triangular teeth consists of two teeth.

[0009] Preferably, the punch component includes a plurality of clamps linearly arrayed and elastically mounted on the front end of the needle holder. A clamp cover is fitted to the front end of the clamp, and a cross punch is clamped between the clamp cover and the clamp. The cross punch extends from the lower end of the clamp cover and the clamp. A screw is screwed through the clamp and the clamp cover. A roller is mounted on the upper end of the clamp. An arc-shaped protrusion is provided in the middle of the lower end of the stamping frame. One of the rollers on the clamp is pressed against the lower end of the arc-shaped protrusion.

[0010] Preferably, a guide rod is fixedly installed at the rear end of the clamp, a rod sleeve is slidably installed on the outer surface of the guide rod, the rod sleeve is fixed to the needle seat, and a lifting spring is wound around the outer side of the guide rod, with the two ends of the lifting spring being fixed to the upper end of the rod sleeve and the upper end of the guide rod, respectively.

[0011] Preferably, the clamping component includes a servo motor that passes through the upper front part of the punching table, and a die is coaxially fixedly mounted on the output end of the servo motor. Bolts are screwed through both ends of the die, and pressure blocks are rotatably mounted on the ends of the bolts.

[0012] Preferably, a servo push cylinder is fixedly installed at the rear end of the servo motor, and the servo push cylinder is fixed to the punching table.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. When the cross punch is raised after each punching operation, the infrared photoelectric sensor detects the end of the cross punch. If the cross punch is detected, it means that the cross punch is not broken; otherwise, if the cross punch is not detected, it means that the cross punch is broken. This allows for timely detection of cross punch breakage. At the same time, the second servo push cylinder will fully retract to raise the punching frame to the adjustment position. During this process, the pressure rod will press the reset rod, thereby driving the needle shifting frame to move and push the slide. This allows the needle shifting claw on the slide to abut against the vertical surface of the needle shifting block and move it, thereby causing the needle seat to move laterally. This removes the broken cross punch from the punching area and allows the next cross punch to move to the punching area to await punching operations. This process can detect cross punch breakage in a timely manner and automatically replace and adjust it, thus avoiding the need for manual replacement by workers every time it breaks, effectively simplifying the use.

[0014] 2. When the needle holder moves to the punching area, the roller at the punching area will contact the arc-shaped protrusion on the stamping frame. Guided by the arc-shaped protrusion, the roller will move downward, thereby moving the punching area punching area downward. At the same time, the lifting spring will support the other punchings, keeping them in the raised state. This ensures that when the punching area punching area punches downward, the other punchings will not contact the workpiece and affect the punching, thus ensuring that the punching operation is carried out smoothly.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] This invention provides a technical solution: such as Figures 1-8The diagram shows a fine-denier spinneret punching device with an adjustable structure, comprising a punching table 1. A platform 37 is fixedly installed on the upper rear part of the punching table 1. A second servo cylinder 8 is installed through the upper end of the platform 37, which supports the second servo cylinder 8. A punching frame 6 is fixedly installed at the output end of the second servo cylinder 8, which controls the lifting and lowering of the punching frame 6. A T-shaped slide bar 14 is fixedly installed between the two ends of the punching frame 6, and the outer surface of the T-shaped slide bar 14 slides smoothly. The device is equipped with a needle holder 13, and a T-shaped slide bar 14 serves to slide the needle holder 13. A punch is provided at the front end of the needle holder 13. When all the cross punches 31 on the needle holder 13 are broken, the needle holder 13 can be directly removed and replaced with a new needle holder 13. A slide block 11 is connected to the inner side of the stamping frame 6. A reset rod 24 is elastically installed through the end of the slide block 11. A slide frame 21 is slidably installed on the upper end of the slide block 11. The slide block 11 serves to allow the reset rod 24 and the slide frame 21 to slide. The slide frame 21 and the reset rod... A needle shifter 12 is rotatably mounted between 24, and a needle shifter pawl 20 is rotatably mounted at the end of the slide 21. The slide 21 serves to support the needle shifter pawl 20. Multiple needle shifter blocks 19 extend linearly from the upper end of the needle holder 13. When the needle shifter pawl 20 moves the needle shifter blocks 19 to drive the needle holder 13 to move laterally, and then resets, the end of the needle shifter pawl 20 is pushed upwards by the inclined surface of the next needle shifter block 19, allowing it to smoothly pass through the next needle shifter block 19. The press frame 6 is normally reset to wait for the next actuation. An infrared photoelectric sensor 26 is installed at the rear of the press frame 6. The infrared photoelectric sensor 26 is connected to the second servo push cylinder 8 through a controller. The infrared photoelectric sensor 26 detects whether the cross punch 31 is broken and drives the second servo push cylinder 8 to fully retract through the controller, so as to drive the press frame 6 to rise to the adjustment position for automatic replacement and adjustment. A pressure rod 35 is installed above the reset rod 24. The pressure rod 35 is fixed to the table plate 37. A clamping part is installed at the front of the upper end of the punching table 1.

[0019] Two guide rods 7 are symmetrically fixedly installed on the upper end of the stamping frame 6. The platform 37 is slidably installed on the outer surface of the guide rods 7. The guide rods 7 serve to guide the stamping frame 6. A fixing frame 5 is fixedly installed on the outer surface of the infrared photoelectric sensor 26. The lower end of the fixing frame 5 is fixed to the punching table 1. The fixing frame 5 serves to fix the infrared photoelectric sensor 26.

[0020] A reset spring 23 is wound around the outside of the reset rod 24. The reset spring 23 pushes the reset rod 24 to reset. The two ends of the reset spring 23 are fixed to the upper end of the reset rod 24 and the upper end of the slide 11, respectively. A top claw bracket 34 is attached to the side of the needle shifting claw 20. The top claw bracket 34 can limit the needle shifting claw 20 so that the needle shifting claw 20 has enough pushing force to move the needle shifting block 19. The end of the top claw bracket 34 is fixed to the slide 21.

[0021] A connecting frame 9 is fixedly installed at the rear end of the slide block 11. The end of the connecting frame 9 is fixed to the stamping frame 6. The connecting frame 9 serves to fix the slide block 11. A bent frame 10 is fixedly installed at the lower end of the connecting frame 9. Two guide posts 17 are slidably installed through the end of the bent frame 10. A pin fixing block 15 is fixedly installed between the ends of the two guide posts 17. The guide posts 17 serve to guide the pin fixing block 15. The pin fixing block 15 is pressed against the rear end of the pin seat 13. A tensioning spring 18 is wound around the outside of the guide posts 17. The tensioning spring 18 serves to push the pin fixing block 15. The tension spring 18 is fixed at both ends to the bending frame 10 and the needle fixing block 15 respectively. Multiple sets of triangular teeth 16 are linearly arrayed and fixed at the rear end of the needle holder 13. The triangular holes on the needle fixing block 15 engage with one set of triangular teeth 16, which ensures that the needle holder 13 will not shift laterally when there is no external force. When it is moved by an external force, the triangular holes on the needle fixing block 15 will separate from the triangular teeth 16 under the guidance of the inclined surface of the triangular teeth 16, so that the needle holder 13 can shift laterally normally. There are two triangular teeth 16 in each set.

[0022] The punch assembly includes multiple clamps 30 linearly arrayed and elastically mounted on the front end of the punch holder 13. A clamp cover 28 is fitted to the front end of each clamp 30, clamping a cross punch 31 between the clamp cover 28 and the clamp 30. The clamps 30 and the clamp cover 28 clamp and secure the cross punch 31. The cross punch 31 extends from the lower ends of the clamp cover 28 and the clamp 30. A screw 27 is screwed through and tightened between the clamp 30 and the clamp cover 28. By loosening the screw 27, the clamp 30 can be separated from the clamp cover 28, allowing for the replacement of a broken cross punch 31. A roller 33 is mounted on the upper end of the clamp 30, and an arc-shaped protrusion 36 is provided in the middle of the lower end of the punching frame 6. One of the rollers 33 on the clamp 30 is pressed against the lower end of the arc-shaped protrusion 36. When the needle seat 13 moves to the side and moves the cross punch 31 to the punching area, the roller 33 located at the cross punch 31 will contact the arc-shaped protrusion 36 on the stamping frame 6. Under the guidance of the arc-shaped protrusion 36, the roller 33 will be driven to move down, thereby driving the cross punch 31 in the punching area to move down. At the same time, the lifting spring 29 will support the other cross punches 31 to keep them in the raised state, so as to ensure that when the cross punches 31 in the punching area move down to punch, the other cross punches 31 will not contact the workpiece and affect the punching, thus ensuring that the punching operation is carried out smoothly.

[0023] A guide rod 25 is fixedly installed at the rear end of the clamp 30. When the arc-shaped protrusion 36 pushes the cross punch 31 in the punching area downward, the upper end of the guide rod 25 will press against the needle seat 13, so that the upper and lower positions of the cross punch 31 are firmly restricted. A rod sleeve 32 is slidably installed on the outer surface of the guide rod 25. The guide rod 25 and the rod sleeve 32 play the role of guiding the clamp 30. The rod sleeve 32 is fixed to the needle seat 13. A lifting spring 29 is wound around the outside of the guide rod 25. The lifting spring 29 plays the role of lifting the cross punch 31. The two ends of the lifting spring 29 are fixed to the upper end of the rod sleeve 32 and the upper end of the guide rod 25, respectively.

[0024] The clamping component includes a servo motor 3 that passes through the upper front part of the punching table 1. The output end of the servo motor 3 is coaxially fixedly mounted with a die 4. The servo motor 3 can drive the workpiece on the die 4 to rotate a certain angle so as to process the irregular hole on the upper ring of the workpiece. Both ends of the die 4 are screwed with bolts 38. The ends of the bolts 38 are rotatably mounted with pressure blocks 22. Rotating the bolts 38 can drive the pressure blocks 22 to move down and clamp the workpiece on the die 4.

[0025] A servo push cylinder 2 is fixedly installed at the rear end of the servo motor 3. The servo push cylinder 2 will push the servo motor 3 and the die 4 forward a certain distance, thereby moving the workpiece forward a certain distance so as to process the other ring of irregular holes on the workpiece. The servo push cylinder 2 is fixed to the punching table 1.

[0026] During punching, the workpiece is placed on the die 4, and the bolt 38 is rotated to move the pressure block 22 downward, clamping the workpiece onto the die 4. Then, the second servo cylinder 8 moves the stamping frame 6 downward, which in turn moves the cross punch 31 downward to punch the workpiece. The second servo cylinder 8 then retracts halfway to lift the cross punch 31. Simultaneously, the servo motor 3 rotates the workpiece on the die 4 by a certain angle. The cross punch 31 then moves downward again to punch the workpiece, and so on. After one ring of irregular holes on the workpiece is processed, the first servo cylinder 2 pushes the servo motor 3 and the die 4 forward a certain distance, moving the workpiece forward a certain distance. The cross punch 31 then moves downward again to punch the workpiece, processing another ring of irregular holes on the workpiece, and so on. During the punching process, when the cross punch 31 is lifted after each punch, the infrared photoelectric sensor 26 detects the end of the cross punch 31. The system performs a test. If the cross punch 31 is detected, it means that the cross punch 31 is not broken. Conversely, if the cross punch 31 is not detected, it means that the cross punch 31 is broken. This allows for timely detection of a broken cross punch 31. At the same time, the second servo push cylinder 8 will fully retract to drive the stamping frame 6 to rise to the adjustment position. During this process, the pressure rod 35 will press the reset rod 24, thereby driving the needle shifting frame 12 to move and push the slide 21. This allows the needle shifting claw 20 on the slide 21 to abut against the vertical surface of the needle shifting inclined block 19 and move it, thereby causing the needle seat 13 to move laterally. This allows the broken cross punch 31 on the needle seat 13 to leave the punching area and allows the next cross punch 31 to move to the punching area to wait for punching operations. This process can detect a broken cross punch 31 in time and automatically replace and adjust it, thus avoiding the phenomenon that workers need to manually replace it every time it breaks, effectively facilitating use.
