Description

Technical Field

[0001] This utility model relates to a high-efficiency punching machine with a built-in burr removal component, belonging to the field of punching machine technology. Background Technology

[0002] A punching machine is a mechanical device used to punch various desired holes in materials. This equipment is widely used in many fields, including but not limited to metal processing, non-metal processing, and the processing of certain special materials. The working principle of a punching machine is relatively simple; it mainly uses a die to punch and shear the material to achieve the purpose of punching. During operation, the punch head of the punching machine, driven by power, impacts the material at a certain speed, thereby forming holes in the material. Depending on the requirements, a punching machine can punch holes of different diameters, shapes, and positions.

[0003] Punching machines are very important mechanical equipment. During the punching process, various reasons may cause burrs to be generated on the workpiece. Tearing, deformation and other phenomena at the punching position may cause burrs to be generated. Since burrs are mainly located at the edge of the hole on the surface and bottom of the workpiece, although surface burrs are easy to remove, burrs generated at the edge of the hole on the bottom of the workpiece after punching are not easy to clean effectively. It is necessary to turn the workpiece over before operating, which affects the workpiece processing efficiency and makes it difficult to achieve efficient burr removal on the workpiece during punching. Utility Model Content

Detailed Implementation

[0027] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0028] like Figure 1-4 As shown, a high-efficiency punching machine with a built-in burr removal component includes:

[0029] The machine base 1 has a stand 2 fixedly installed on the top of the machine base 1. The top and side walls of the stand 2 are respectively provided with a punching mechanism and a pressing mechanism. The machine base 1 has a partition 9 fixedly installed inside, and a guide mechanism is provided above the partition 9.

[0030] A sleeve 12 is fixedly installed in the middle of the base 1. A piston 14 is sealed and slidably installed inside the sleeve 12. The top of the piston 14 is rotatably connected to the gear shaft 15, and the gear shaft 15 is movably sleeved inside the sleeve 12. A grinding head 16 corresponding to the punching mechanism is fixedly installed on the top of the gear shaft 15. A transmission mechanism is provided at the bottom of the partition 9 located on one side of the sleeve 12.

[0031] The punching mechanism includes a hydraulic cylinder 3 and a punch 4. The hydraulic cylinder 3 is fixedly connected to the top of the stand 2. The telescopic end of the hydraulic cylinder 3 is fixedly connected to the punch 4, and the edge of the punch 4 is provided with an arc groove 5. The clamping mechanism consists of a first cylinder 6 and a pressure plate 7. The first cylinder 6 is rotatably connected to the side wall of the stand 2. The telescopic end of the first cylinder 6 is rotatably connected to one end of the pressure plate 7, and the other end of the pressure plate 7 is rotatably connected to the side wall of the stand 2. A platform 8 is fixedly installed on the top of the machine base 1, and the pressure plate 7 contacts the workpiece placed on the surface of the platform 8.

[0032] In this technical solution, after the workpiece is placed on the platform 8, the first cylinder 6 drives the pressure plate 7 to press and fix the workpiece. Then, the hydraulic cylinder 3 is started to drive the punch 4 to move down to punch the workpiece. The excess material generated during punching falls into the machine base 1. After punching is completed, the punch 4 continues to move down, and the arc groove 5 on its edge contacts the edge of the hole and squeezes the edge of the hole. The burrs generated during punching are squeezed and cleaned by the arc groove 5, ensuring that the edge of the hole is smooth and burr-free.

[0033] The guiding mechanism consists of a guide plate 11 and a second cylinder 10. The guide plate 11 is rotatably connected to the top of the machine base 1. Both the machine base 1 and the platform 8 are provided with through holes for the discharge of residual material. The guide plate 11 is inclined and set on one side of the through hole. The second cylinder 10 is rotatably connected to the top surface of the partition plate 9. The telescopic end of the second cylinder 10 is rotatably connected to the guide plate 11. An opening 25 is provided on one side of the partition plate 9. An inclined plate is fixedly installed at the bottom of the partition plate 9 on the side of the opening 25. A rotating plate is provided on the outer wall of the machine base 1 corresponding to the inclined plate.

[0034] In this technical solution, when the residual material generated by punching falls, it contacts the guide plate 11. The guide plate 11 guides the residual material to fall from the opening 25 into the bottom of the machine base 1, and separates it with the inclined plate, which facilitates the subsequent removal by opening the rotating plate. When punching is completed, the second cylinder 10 is started. When the second cylinder 10 shortens, it drives the guide plate 11 to rotate to a more vertical position, so that the grinding head 16 does not contact the guide plate 11 when it rises.

[0035] An air pump 23 is fixedly installed at the bottom of the base 1. The air pump 23 is connected to the bottom of the sleeve 12 through the connecting pipe 24. The bottom of the sleeve 12 has a small hole for gas discharge. A stabilizing sleeve 17 is rotatably connected inside the end of the partition 9. The inner wall of the stabilizing sleeve 17 has a toothed groove that meshes with the gear shaft 15.

[0036] In this technical solution, when the air pump 23 is started, the connecting pipe 24 delivers gas to the bottom end of the sleeve 12, and the remaining small part of the gas is discharged from the fine hole. When the gas delivery volume increases, the air pressure overcomes the elasticity of the spring 13 and the gravity of the gear shaft 15, forcing it to move upward. The piston 14 pushes the gear shaft 15 and the grinding head 16 to move to the bottom edge of the workpiece. When the gear shaft 15 moves, its surface always slides on the tooth groove of the gear 20 and the inner wall of the stabilizing sleeve 17.

[0037] The transmission mechanism consists of a rotating shaft 18, with a gear 20 fixedly mounted at one end of the rotating shaft 18. The gear 20 extends into the sleeve 12 and meshes with the gear shaft 15. The rotating shaft 18 is rotatably connected to the bottom of the partition 9. A motor 21 is fixedly mounted on one side of the partition 9. The output end of the motor 21 and the rotating shaft 18 are both fixedly connected to pulleys 19, and the pulleys 19 are connected to each other by a belt 22. A connecting shaft is fixedly connected to the top of the piston 14. The connecting shaft is rotatably connected to the bottom end of the gear shaft 15. The piston 14 is positioned above the connecting pipe 24.

[0038] In this technical solution, after the grinding head 16 moves into position, the motor 21 is started, and the rotating shaft 18 is driven to rotate by the pulley 19 and the belt 22. When the rotating shaft 18 drives the gear 20 to rotate, it drives the gear shaft 15 to rotate synchronously. The gear shaft 15 rotates on the connecting shaft at the top of the piston 14 and drives the grinding head 16 to rotate. The gear shaft 15 also drives the stabilizing sleeve 17 to rotate inside the partition plate 9. The stabilizing sleeve 17 ensures the stable rotation of the gear shaft 15. At the same time, the air pressure makes the grinding head 16 press against the edge of the hole at the bottom of the workpiece to remove and clean the burrs. When the operation is completed, the motor 21 and the air pump 23 stop working. The elasticity of the spring 13 and the weight of the gear shaft 15 reset it. The gas inside the sleeve 12 is discharged from the fine hole, thereby resetting the grinding head 16. Then the guide plate 11 is rotated to the top of the grinding head 16 to prepare for the guidance of the remaining material during subsequent punching.

The protection scope of this utility model is defined by the appended claims.
