Description

Technical Field

[0001] This utility model relates to the field of punching device technology, and in particular to a continuous punching device for hardware processing. Background Technology

[0002] A continuous punching device for metal processing is an automated or semi-automatic machine specifically designed for continuous, batch punching of metal sheets, profiles, and other metal products. Its core function is to quickly and accurately punch multiple through holes or slots of uniform size on the surface of the metal workpiece through the cooperation of the punch and the backing plate. Structurally, this type of device typically consists of a frame, a feeding mechanism, a punching mechanism, a positioning component, and a control system. The feeding mechanism is responsible for continuously conveying the workpieces to be processed to the punching area at preset intervals. The punching mechanism drives the punch to reciprocate, working in conjunction with the backing plate to complete the punching action. The positioning component ensures the positional accuracy of each punch.

[0003] Existing continuous punching equipment for hardware processing requires frequent replacement of punches and matching backing plates when dealing with punching requirements of different specifications (the backing plate has punches that are compatible with the punches to receive the punches and prevent damage to the back of the workpiece). However, the disassembly and installation of the backing plates are generally cumbersome. Traditional backing plates are mostly fixed to the worktable by multiple bolts or clips. When replacing them, the fasteners must be disassembled one by one, requiring additional cleaning or the use of tools to loosen them, which is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a continuous punching device for hardware processing, so as to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, one embodiment of this utility model provides a continuous punching device for hardware processing, including a base frame. A bearing plate is fixedly mounted on the top of the base frame by bolts. An adjusting disc is rotatably connected to the top of the bearing plate. A drive rod is fixedly connected to the bottom of the adjusting disc. A motor is fixedly mounted on the bottom of the bearing plate by a motor bracket. Gears are fixedly connected to the output end of the motor and the bottom end of the drive rod, and the two gears mesh with each other. A mounting frame is fixedly mounted on the top surface of the bearing plate by bolts. A punching machine body is fixedly connected to the top of the mounting frame. Several punches of different diameters are opened through the top of the adjusting disc. The punch needle part of the punching machine body corresponds vertically to the punches. Two symmetrically arranged hydraulic cylinders are fixedly connected to the top of the mounting frame. A lifting plate is fixedly connected to the output end of the two hydraulic cylinders. A spline shaft is fixedly connected to the bottom surface of the lifting plate. The bottom surface of the lifting plate is in contact with the top surface of the adjusting disc, and the spline shaft is engaged with the adjusting disc.

[0007] Preferably, in any of the above embodiments, the top surface of the adjusting plate is provided with a spline groove, and the spline shaft is engaged with the adjusting plate through the spline groove.

[0008] Preferably, in any of the above solutions, the top of the lifting plate is fixedly connected to two symmetrically arranged guide rods, and several of the guide rods are slidably connected to the mounting frame.

[0009] Preferably, in any of the above embodiments, a pad is fixedly connected to the top surface of the adjusting plate, and an arc-shaped groove is provided on one side of the pad, through which the adjusting plate is slidably connected to the pad.

[0010] Preferably, in any of the above embodiments, the top surface of the support plate is provided with a rotating groove, and the adjusting plate is rotatably connected to the support plate through the rotating groove.

[0011] Preferably, in any of the above embodiments, the bottom of the support plate is provided with a through hole that communicates with the rotating groove, and the drive rod is rotatably connected to the support plate through the through hole.

[0012] Preferably, in any of the above embodiments, the bottom of the support plate is provided with a discharge port that communicates with the rotating groove, the base frame is provided with a storage frame, the discharge port coincides with the circle of the punch, and the discharge port is located directly above the storage frame.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. When changing the punching specification, activate the hydraulic cylinder to raise the lifting plate, disengaging the splined shaft from the adjusting plate. Then, start the motor; the gear at the motor's output drives the gear at the bottom of the drive rod, causing the adjusting plate to rotate on the support plate until the corresponding hole on the adjusting plate aligns with the punch of the punching machine body. Finally, reverse the hydraulic cylinder, lowering the lifting plate and re-engaging the splined shaft with the adjusting plate, locking the adjusting plate. This design achieves rapid switching between different punching diameters by driving the adjusting plate with a motor, and uses a hydraulic cylinder to control the splined shaft for locking and unlocking. It eliminates the need to disassemble and replace the pad or punch, avoiding the cumbersome steps of disassembling fasteners in traditional devices. This reduces operation time and labor intensity during switching, significantly improving flexibility and efficiency in meeting different punching specifications.

[0014] 2. Before punching, a rotating groove ensures the adjusting plate rotates stably on the support plate. The guide rod slides along the mounting frame as the lifting plate moves, ensuring the splined shaft accurately engages with the adjusting plate. During punching, a pad supports the workpiece, and an arc-shaped groove adapts to the rotation trajectory of the adjusting plate, preventing direct friction between the workpiece and the adjusting plate. Waste generated during punching falls through the punch hole into the discharge port and is ultimately collected in the storage box. In this structure, the rotating groove restricts the movement trajectory of the adjusting plate, the guide rod ensures smooth lifting of the lifting plate, and the engagement of the splined shaft with the adjusting plate enhances locking stability, effectively preventing the adjusting plate from shifting during punching. The pad protects the back of the workpiece and reduces wear, and the discharge port and storage box work together to achieve orderly waste collection. This improves the accuracy of the punching position and ensures the stability of equipment operation and the cleanliness of the processing environment. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0018] like Figures 1 to 5As shown, a continuous punching device for hardware processing includes a base frame 1. A bearing plate 2 is fixedly mounted on the top of the base frame 1 by bolts. An adjusting plate 3 is rotatably connected to the top of the bearing plate 2. A drive rod 4 is fixedly connected to the bottom of the adjusting plate 3. A motor 5 is fixedly mounted on the bottom of the bearing plate 2 by a motor bracket. Gears 6 are fixedly connected to the output end of the motor 5 and the bottom end of the drive rod 4. The two gears 6 are meshed. A mounting frame 7 is fixedly mounted on the top surface of the bearing plate 2 by bolts. A punching machine body 8 is fixedly connected to the top of the mounting frame 7. Several punch holes 9 of different diameters are opened through the top of the adjusting plate 3. The punching needle part of the punching machine body 8 corresponds vertically to the punch holes 9. Two symmetrically arranged hydraulic cylinders 10 are fixedly connected to the top of the mounting frame 7. A lifting plate 11 is fixedly connected to the output end of the two hydraulic cylinders 10. A spline shaft 12 is fixedly connected to the bottom surface of the lifting plate 11. The bottom surface of the lifting plate 11 is in contact with the top surface of the adjusting plate 3. The spline shaft 12 is engaged with the adjusting plate 3.

[0019] As an optional technical solution of this utility model, the top surface of the adjusting plate 3 is provided with a spline groove 13, and the spline shaft 12 is engaged with the adjusting plate 3 through the spline groove 13. The spline groove 13 on the top surface of the adjusting plate 3 and the spline shaft 12 cooperate to achieve engagement. The spline connection structure enables the adjusting plate 3 to transmit greater torque between the lifting plate 11 and the positioning to be accurate. It can reliably lock the adjusting plate 3 to prevent it from rotating during the punching process, and can also smoothly separate when switching punching specifications, ensuring the stability and accuracy of locking and unlocking the adjusting plate 3.

[0020] As an optional technical solution of this utility model, the top of the lifting plate 11 is fixedly connected with two symmetrically arranged guide rods 14, and several guide rods 14 are slidably connected to the mounting frame 7. The guide rods 14 at the top of the lifting plate 11 are slidably connected to the mounting frame 7 to provide guidance for the lifting movement of the lifting plate 11, avoid the lifting plate 11 from shifting or tilting under the drive of the hydraulic cylinder 10, ensure that the spline shaft 12 can be accurately aligned with the spline groove 13 to complete the engagement or disengagement, and improve the stability and reliability of the movement of the lifting plate 11.

[0021] As an optional technical solution of this utility model, a pad 15 is fixedly connected to the top surface of the adjusting plate 3. An arc groove 20 is provided on one side of the pad 15. The adjusting plate 3 is slidably connected to the pad 15 through the arc groove 20. The pad 15 on the top surface of the adjusting plate 3 can support and protect the workpiece, avoiding direct contact between the workpiece and the adjusting plate 3, which would cause surface wear. The arc groove 20 on the pad 15 is adapted to the rotation trajectory of the adjusting plate 3, ensuring that the adjusting plate 3 maintains a stable fit with the pad 15 when rotating to switch punching, without affecting the placement of the workpiece and the punching operation.

[0022] As an optional technical solution of this utility model, the top surface of the support plate 2 is provided with a rotating groove 16, and the adjusting plate 3 is rotatably connected to the support plate 2 through the rotating groove 16. The rotating groove 16 on the top surface of the support plate 2 provides a rotating track for the adjusting plate 3, restricts the radial displacement of the adjusting plate 3, and makes the adjusting plate 3 rotate stably only along the rotating groove 16, avoiding the adjusting plate 3 from shifting or shaking during rotation, and ensuring the alignment accuracy between the punch 9 on the adjusting plate 3 and the punch part of the punching machine body 8.

[0023] As an optional technical solution of this utility model, the bottom of the support plate 2 is provided with a through hole 17 that communicates with the rotating groove 16. The drive rod 4 is rotatably connected to the support plate 2 through the through hole 17. The through hole 17 at the bottom of the support plate 2 provides a rotation channel for the drive rod 4, ensuring that the drive rod 4 can stably connect the adjusting plate 3 and the gear 6, so that the power of the motor 5 can be accurately transmitted to the adjusting plate 3 through the gear 6 and the drive rod 4, ensuring the smoothness and stability of the rotation of the adjusting plate 3, while avoiding interference between the drive rod 4 and the support plate 2.

[0024] As an optional technical solution of this utility model, the bottom of the support plate 2 is provided with a discharge port 18 that communicates with the rotating groove 16. The base frame 1 is equipped with a storage frame 19. The discharge port 18 coincides with the circle of the punch 9 and is located directly above the storage frame 19. The discharge port 18 at the bottom of the support plate 2 corresponds to the punch 9 of the adjustment plate 3 and is located directly above the storage frame 19. The waste generated by punching can fall directly into the storage frame 19 through the punch 9 and the discharge port 18, realizing the automatic collection of waste, avoiding the accumulation of waste on the adjustment plate 3 or the support plate 2, affecting subsequent punching operations, and keeping the processing environment clean.

[0025] A continuous punching device for hardware processing, the working principle of which is as follows: 1): Start the hydraulic cylinder 10, so that its output end drives the lifting plate 11 to rise, and the spline shaft 12 disengages from the locking of the adjusting plate 3 along with the lifting plate 11.

[0026] 2): Start the motor 5. The gear 6 at the output end of the motor 5 drives the gear 6 at the bottom end of the drive rod 4 to rotate, so that the adjustment plate 3 rotates on the support plate 2 until the punch 9 of the corresponding diameter on the adjustment plate 3 is aligned with the punch part of the punching machine body 8.

[0027] 3): Reverse start hydraulic cylinder 10, lifting plate 11 descends, spline shaft 12 re-engages with adjusting plate 3, and locking adjusting plate 3 is completed.

[0028] In summary, when the punching specification needs to be changed, the hydraulic cylinder 10 is activated, causing its output end to drive the lifting plate 11 to rise. The spline shaft 12 disengages from the adjusting plate 3 along with the lifting plate 11. Then, the motor 5 is activated, and the gear 6 at the output end of the motor 5 drives the gear 6 at the bottom end of the drive rod 4 to rotate, causing the adjusting plate 3 to rotate on the bearing plate 2 until the punch 9 of the corresponding diameter on the adjusting plate 3 is aligned with the punch part of the punching machine body 8. Finally, the hydraulic cylinder 10 is activated in reverse, the lifting plate 11 descends, and the spline shaft 12 re-engages with the adjusting plate 3, completing the locking of the adjusting plate 3. This design uses a motor 5 to drive the adjustment plate 3 to rotate, enabling rapid switching between different hole diameters for punching 9. A hydraulic cylinder 10 controls the spline shaft 12 for locking and unlocking, eliminating the need to disassemble and replace the pad or punch. This avoids the tedious steps of disassembling fasteners in traditional devices, reducing operation time and labor intensity during switching. It significantly improves flexibility and efficiency in meeting different punching requirements. Before punching, the rotating groove 16 ensures stable rotation of the adjustment plate 3 on the support plate 2. The guide rod 14 slides along the mounting frame 7 as the lifting plate 11 moves, ensuring the spline shaft 12 accurately engages with the adjustment plate 3. During punching, the pad 15 supports the workpiece, and the arc-shaped groove 20 adapts to the rotation trajectory of the adjustment plate 3, preventing direct friction between the workpiece and the adjustment plate 3. Waste generated during punching falls through the punch 9 into the discharge port 18 and is ultimately collected in the storage frame 19. In this structure, the rotating groove 16 restricts the movement trajectory of the adjusting plate 3, the guide rod 14 ensures the smooth lifting of the lifting plate 11, and the snap-fit ​​between the spline shaft 12 and the adjusting plate 3 enhances the locking stability and effectively prevents the adjusting plate 3 from shifting during punching. The pad 15 protects the back of the workpiece and reduces wear, and the discharge port 18 cooperates with the storage frame 19 to achieve orderly collection of waste materials, which not only improves the accuracy of the punching position, but also ensures the stability of equipment operation and the cleanliness of the processing environment.
