Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a punching device for processing metal products. Background Technology

[0002] The punching equipment used in metal product processing is mainly the punching machine. A punching machine is a mechanical device that uses punching dies to complete punching operations on materials under the drive of a power mechanism. It is suitable for various operations such as thin sheet processing, stamping, and molding of metal sheets, and is an indispensable piece of equipment in metal product processing.

[0003] A search revealed a Chinese patent that discloses a punching device for metal product processing (authorization announcement number CN212310557U), which also belongs to the field of metal processing technology. The device includes "a base with four parallel limiting rods distributed on it, the bottom of which is connected to the base, and a stop block on each limiting rod; a sleeve fitted over the limiting rods, forming a sliding connection; a pressure plate connected to the sleeve; and a support plate connected to the top of the limiting rods on one side." While this patented technology allows for the loading and unloading of workpieces by moving the support base, it does not fully realize the benefits of this technology.

[0004] However, in the actual application of this patented technology, when the punch head is inserted into the hole of the support, the workpiece will be fixedly sleeved on the outside of the punch head. The operator needs to manually remove the workpiece from the outside of the punch head, which is inconvenient and reduces the punching efficiency of metal products. In order to solve the above problems, the inventor proposes a punching equipment for metal product processing. Utility Model Content

[0005] In order to solve the problem of preventing metal products from being sleeved on the outside of the punching head after punching, the purpose of this utility model is to provide a punching device for metal product processing.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a punching device for metal product processing, including a worktable, a vertical plate fixedly connected to one side of the top of the worktable, a movable plate slidably engaged with the side of the vertical plate near the worktable, an mounting plate fixedly connected to the side of the movable plate away from the vertical plate, symmetrically distributed guide rods provided at the bottom of the mounting plate, a pressure plate fixedly connected between the bottom ends of the guide rods, a punching head fixedly connected to the middle of the bottom end of the mounting plate, the bottom end of the punching head movably penetrating through the pressure plate, a spring provided between the bottom surface of the mounting plate and the top end of the pressure plate, the spring movably sleeved on the outside of the guide rods, and the top ends of the guide rods all movably extending to the top end of the mounting plate and fixedly connected to a limit block.

[0007] Preferably, a rotating column is rotatably connected to the top of the workbench near the vertical plate, a cross plate is fixedly connected to the top of the rotating column, and a work station slot is provided at each of the four corners of the top of the cross plate. A gear one is fixedly connected to the outer side of the rotating column, and a stepper motor is fixedly installed on the top of the workbench near the rotating column. A gear two is fixedly connected to the drive end of the stepper motor, and gear one and gear two are meshed together.

[0008] Preferably, the cross plate has through holes on the side near the work station slot, and a load-bearing block is fixedly connected to the top of the workbench on the side near the vertical plate. The load-bearing block and the workbench have a discharge chute that communicates with each other. The longitudinal section of the discharge chute is trapezoidal, and the through holes correspond to the positions of the discharge chute.

[0009] Preferably, a turntable is rotatably connected to the top of the vertical plate near the workbench, and a connecting rod is rotatably connected to the side of the turntable away from the vertical plate. The bottom end of the connecting rod is rotatably connected to the top of the moving plate. A servo motor is fixedly installed on the side of the vertical plate away from the turntable, and the drive end of the servo motor is fixedly connected to the rotation shaft of the turntable.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. After the punch head drills a hole in the metal plate, the metal plate squeezes against the punch head, causing the metal plate to be fitted onto the outside of the punch head. At this time, when the punch head moves upward, the spring force pushes the pressure plate downward, simultaneously pushing the metal plate fitted onto the outside of the punch head downward, thereby peeling the metal plate off the outer surface of the punch head. This avoids manually removing the metal plate from the outside of the punch head, reducing labor input and improving punching efficiency.

[0012] 2. The stepper motor drives gear two to rotate, and the meshing connection between gear one and gear two drives the rotating column and cross plate to rotate, thereby switching the work station slot. This allows for the unloading operation of another metal product that has already been punched while punching a metal product, further improving the continuity of the punching operation.

Detailed Implementation

[0019] 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.

[0020] Example: Figure 1-4 As shown, this utility model provides a punching device for metal product processing, including a workbench 1. A vertical plate 2 is fixedly connected to one side of the top of the workbench 1. A movable plate 3 is slidably engaged with the side of the vertical plate 2 near the workbench 1. An mounting plate 5 is fixedly connected to the side of the movable plate 3 away from the vertical plate 2. A guide rod 6 is symmetrically distributed at the bottom of the mounting plate 5. A pressure plate 7 is fixedly connected between the bottom ends of the guide rods 6. A punching head 21 is fixedly connected to the middle of the bottom end of the mounting plate 5. The bottom end of the punching head 21 movably passes through the pressure plate 7. A spring 8 is provided between the bottom surface of the mounting plate 5 and the top end of the pressure plate 7. The spring 8 is movably sleeved on the outside of the guide rods 6.

[0021] A rotating column 9 is rotatably connected to the top of the workbench 1 near the vertical plate 2. A cross plate 10 is fixedly connected to the top of the rotating column 9. A work station slot 14 is provided at each of the four corners of the top of the cross plate 10. A gear 11 is fixedly connected to the outside of the rotating column 9. A stepper motor 12 is fixedly installed on the top of the workbench 1 near the rotating column 9. A gear 2 13 is fixedly connected to the drive end of the stepper motor 12. Gear 11 and gear 2 13 are meshed together.

[0022] By adopting the above technical solution, the stepper motor 12 drives the gear 13 to rotate, and the meshing connection between the gear 11 and the gear 13 drives the rotating column 9 and the cross plate 10 to rotate, thereby switching the work station slot 14. This allows the unloading operation of another metal product that has already been punched to be performed while punching the metal product, further improving the continuity of the punching operation.

[0023] A through hole 15 is provided on the side of the cross plate 10 near the work station slot 14. A load-bearing block 16 is fixedly connected to the top of the workbench 1 near the vertical plate 2. The load-bearing block 16 and the workbench 1 have a discharge groove 17 that communicates with each other. The positions of the through hole 15 and the discharge groove 17 correspond.

[0024] By adopting the above technical solution and by setting the unloading groove 17, when punching metal products, the position of the through hole 15 corresponds to that of the unloading groove 17.

[0025] A turntable 18 is rotatably connected to the top of the vertical plate 2 near the workbench 1. A connecting rod 19 is rotatably connected to the side of the turntable 18 away from the vertical plate 2. The bottom end of the connecting rod 19 is rotatably connected to the top of the moving plate 3. A servo motor 20 is fixedly installed on the side of the vertical plate 2 away from the turntable 18. The drive end of the servo motor 20 is fixedly connected to the rotation shaft of the turntable 18.

[0026] By adopting the above technical solution, the servo motor 20 drives the turntable 18 to rotate, and at the same time drives the top end of the connecting rod 19 to rotate. The moving plate 3 limits the bottom end of the connecting rod 19 and drives the moving plate 3 to move vertically back and forth, thereby realizing the punching operation.

[0027] The top of each guide rod 6 extends movably to the top of the mounting plate 5 and is fixedly connected to the limit block 4.

[0028] By adopting the above technical solution and setting the limiting block 4, the guide rod 6 can be limited to prevent it from coming out of the mounting plate 5.

[0029] The longitudinal section of the unloading chute 17 is trapezoidal.

[0030] By adopting the above technical solution, the longitudinal section of the unloading chute 17 is set into a trapezoidal shape, which facilitates the better discharge of waste generated during the punching of metal products through the unloading chute 17.

[0031] Working principle: When punching metal products, the metal plate is placed inside the corresponding work station slot 14, and then the stepper motor 12 drives the gear 13 to rotate. The gear 11 meshes with the gear 13, and at the same time drives the rotating column 9 and the cross plate 10 to rotate, switching the work station slot 14. When the metal plate to be processed moves directly below the punching head 21, the servo motor 20 drives the turntable 18 to rotate, and at the same time drives the top of the connecting rod 19 to rotate. The moving plate 3 limits the bottom of the connecting rod 19 and drives the moving plate 3 to move vertically back and forth. When the moving plate 3 moves down to the point where the pressure plate 7 contacts the metal plate, it first pushes the guide rod 6 upward and compresses the spring 8. Then the punching head 21 contacts the metal plate, and the spring force of the spring 8 presses the metal plate, which facilitates the punching operation. It can also unload another punched metal product while punching the metal product, improving the continuity of the punching operation.

[0032] After the punch head 21 drills a hole in the metal plate, the metal plate will be squeezed onto the outside of the punch head 21 due to the squeezing action of the metal plate. At this time, when the punch head 21 moves upward, the spring force of the spring 8 pushes the pressure plate 7 downward, and at the same time pushes the metal plate on the outside of the punch head 21 downward, thereby peeling the metal plate off the outer surface of the punch head 21.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
