Description

Technical Field

[0001] This utility model relates to the technical field of punching processing equipment, and in particular to a punching device that can automatically recycle waste materials. Background Technology

[0002] Punching machines are commonly used machining equipment, widely applied in punching processes for materials such as clothing fabrics, metal sheets, and plastic sheets. With the development of industrial production, the requirements for the precision, efficiency, and automation level of punching machines are becoming increasingly stringent.

[0003] Currently, common punching devices on the market mainly consist of a base, a punch rod, a punching tool, and a drive mechanism. The punch rod is typically mounted on the base, and the punching tool is located at the bottom end of the punch rod. The drive mechanism moves the punch rod up and down to perform the punching operation on the workpiece.

[0004] However, a common problem with existing punching devices is the inconvenience of handling the waste generated during punching. The waste produced during the punching process usually falls randomly onto or under the worktable, requiring regular manual cleaning by workers. This not only increases the workload but may also affect the continuity and efficiency of the punching operation.

[0005] In addition, existing punching devices are prone to adhesion between the punch and the waste material during the punching process. Especially in continuous punching operations, the waste material may accumulate around the punch, affecting punching accuracy and efficiency.

[0006] In summary, existing punching devices have significant shortcomings in waste disposal. There is a need for a device that can automatically collect waste during the punching process to prevent waste accumulation from affecting the punching quality, thereby improving the efficiency and quality of punching operations.

The pressure rod passes through the second cavity. A sliding piston is provided on the outer peripheral wall of the pressure rod and is slidably connected to the second cavity. Sealing covers are respectively provided at the upper and lower openings of the second cavity, allowing the pressure rod to slide through, so that a first air cavity and a second air cavity are formed between the sliding piston and the two sealing covers. A first air hole and a second air hole communicating with the first air cavity and the second air cavity are respectively provided at the upper and lower ends of the first cavity. One end of the pressure head is connected to the top of the pressure rod, and the other end of the pressure head is connected to the top of the punch rod, so that the pressure rod drives the punch rod to move up and down with the help of the pressure head.

[0014] Preferably, it also includes an auxiliary block, which includes a connecting portion and a pressing plate;

[0015] The pressure rod is a hollow structure, and a movable rod that can move up and down relative to the pressure rod is also inserted inside the pressure rod.

[0029] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0030] This embodiment discloses a punching device that can be used to punch flexible fabrics. Of course, the material of the object to be punched is not limited and can also be other materials.

[0031] like Figures 1 to 3 The system includes a base 1, a recycling bin 2, and at least one set of actuators mounted on the base 1. The actuators include a punch 30 and a punch 31 located at the bottom of the punch 30. The punch 30 has an airflow channel 32 that communicates with the punch 31. The airflow channel 32 is connected to the recycling bin 2 via a connecting pipe 4. The recycling bin 2 provides negative pressure adsorption force to the airflow channel 32, so that the waste generated by the punch 31 enters the recycling bin 2 through the airflow channel 32.

[0032] In this embodiment, four sets of actuators are installed on the base 1 to perform punching operations simultaneously, thereby improving the efficiency of the punching operation. Moreover, the hole diameter of the puncher 31 in the four sets of actuators can be set to different sizes, so that multiple holes of different specifications can be punched at once.

[0033] The recycling bin 2 is a sealed container made of metal or high-strength plastic. When connected to a vacuum pump or other negative pressure generating device, the recycling bin 2 can produce a stable negative pressure.

[0034] During operation, the punch 31 punches holes in the working surface. The resulting waste material, under the action of negative pressure adsorption, enters the airflow channel 32 through the opening at the bottom of the punch 31, and then enters the recycling bin 2 through the connecting pipe 4, thus achieving automatic collection of waste material. This design not only improves work efficiency but also maintains a clean working environment.

[0035] On the other hand, a frame 8 is also provided, with the base 1 connected to the frame 8 via a second lifting drive 9, which drives the base 1 to move up and down. During punching operations, the second lifting drive 9 moves the base 1 downwards, bringing the punch 31 closer to the working surface to prepare for the punching operation. A recycling bin 2 can also be mounted on the frame 8 to shorten the length of the connecting pipe 4. Specifically, the second lifting drive 9 includes a lead screw assembly and a sliding assembly, with the lead screw assembly driving the base 1 to slide along the sliding assembly.

[0036] On the other hand, such as Figure 4 and Figure 5 The base 1 has a first cavity 10 that runs through its upper and lower surfaces. The punch 30 passes through the first cavity 10, and the bottom and top ends of the punch 30 are located outside the first cavity 10. The punch 30 is fitted with a rotating sleeve 34. The base 1 is also equipped with a drive motor 12 that is connected to the rotating sleeve 34. The drive motor 12 is used to drive the punch 30 to rotate through the rotating sleeve 34, so that the punch 31 punches holes on the working surface based on rotation.

[0037] Specifically, the first cavity 10 is cylindrical, with a diameter slightly larger than that of the punch 30, to ensure that the punch 30 can move freely within it. The inner wall of the first cavity 10 is smooth to reduce friction with the punch 30. In addition, a bearing ring 343 is fitted onto the portion of the punch 30 within the first cavity 10 to effectively reduce the rotational friction of the punch 30.

[0038] The rotating sleeve 34 is sleeved on the outside of the punch 30, forming a coaxial structure with the punch 30. The outside of the rotating sleeve 34 is provided with a transmission part connected to the drive motor 12, which can be a gear, pulley or other transmission structure.

[0039] The drive motor 12 is mounted on the base 1 and is connected to the rotating sleeve 34 via a transmission mechanism. The drive motor 12 can be a servo motor or a stepper motor, and can be adjusted according to actual needs. The drive motor 12 is connected to the rotating sleeve 34 through a transmission mechanism, which can be a gear drive, belt drive, or chain drive, etc.

[0040] On the other hand, the actuator also includes a first lifting drive connected to the punch 30. The first lifting drive is used to drive the punch 30 to move up and down so that the punch 31 contacts or separates from the working surface.

[0041] When the second lifting driver moves the base 1 close to the working surface, the first lifting driver is activated, causing the punch 30 to move down, so that the punch 31 contacts the working surface.

[0042] Furthermore, the outer wall of the punch 30 is connected to the inner wall of the rotating sleeve 34 by a snap-fit ​​structure, so that the rotating sleeve 34 can drive the punch 30 to rotate, and the punch 30 can slide up and down relative to the rotating sleeve 34.

[0043] In this embodiment, the engaging structure can transmit rotational torque without affecting the axial movement of the punch 30.

[0044] Specifically, the rotating sleeve 34 includes a synchronous pulley 340 and a sleeve 341 connected to the synchronous pulley 340. The diameter of the synchronous pulley 340 is larger than the diameter of the sleeve 341. The synchronous pulley 340 is connected to the drive motor 12 for transmission. The engaging structure includes a slot 342 (e.g., a groove 342) provided on the sleeve 341 and extending axially along the sleeve 341. Figure 6 ) and a latching protrusion 33 (such as) provided on the outer wall of the punch 30 and extending along the axial direction of the punch 30. Figure 3 The slot 342 is adapted to the protrusion 33.

[0045] The slot 342 and the protrusion 33 cooperate to form a keyway structure, which can transmit rotational torque while allowing the punch 30 to move freely in the axial direction. This design ensures the reliability of the rotary transmission without affecting the lifting and lowering movement of the punch 30.

[0046] On the other hand, please refer to [further details]. Figure 4 and Figure 5 The first lifting drive includes a pressure rod 50 and a pressure head 51. A second cavity 11 is provided on the base 1, penetrating both its upper and lower surfaces, and the pressure rod 50 passes through the second cavity 11.

[0047] A sliding piston 52 is provided on the outer peripheral wall of the pressure rod 50 and is slidably connected to the second cavity 11. A sealing cover 53 is provided at the upper and lower openings of the second cavity 11, through which the pressure rod 50 can slide, so that a first air cavity 54 and a second air cavity 55 are formed between the sliding piston 52 and the two sealing covers 53.

[0048] The upper and lower ends of the first cavity 10 are respectively provided with a first air hole 110 and a second air hole 111 that communicate with the first air cavity 54 and the second air cavity 55.

[0049] One end of the pressure head 51 is connected to the top of the pressure rod 50, and the other end of the pressure head 51 is connected to the top of the punch rod 30, so that the pressure rod 50 drives the punch rod 30 to move up and down with the help of the pressure head 51.

[0050] In this embodiment, the pressure rod 50 is driven to slide up and down by the pneumatic structure consisting of the sliding piston 52, the sealing cover 53, the first air chamber 54, the second air chamber 55, the first air hole 110 and the second air hole 111, and then the pressure head 51 drives the punch rod 30 to slide up and down.

[0051] In addition, a sleeve 510 is provided at one end of the pressure head 51, and an air nozzle 511 is provided at the other end of the pressure head 51 to mate with the punch rod 30. This not only facilitates assembly, but also prevents the pressure head 51 from deflecting the punch rod 30 because it presses directly above the punch rod 30 through the air nozzle 511.

[0052] During operation, the air pressure in the first air chamber 54 and the second air chamber 55 are controlled by the first air port 110 and the second air port 111, respectively, which enables the sliding piston 52 to move up and down. When the first air chamber 54 is filled with air and the second air chamber 55 is exhausted, the sliding piston 52 moves downward, causing the pressure rod 50 to descend. When the second air chamber 55 is filled with air and the first air chamber 54 is exhausted, the sliding piston 52 causes the pressure rod 50 to move upward.

[0053] On the other hand, such as Figure 5 and Figure 8 The punching device also includes an auxiliary block 6, which includes a connecting part 60 and a pressing plate 61.

[0054] The pressure rod 50 is a hollow structure. Inside the pressure rod 50, there is also a movable rod 56 that can move up and down relative to the pressure rod 50. The bottom end of the movable rod 56 passes through the pressure rod 50 and connects to the connecting part 60 of the auxiliary block 6. The pressure plate 61 is located directly below the punch 31, and the pressure plate 61 is provided with a through hole 62 through which the punch 31 can pass.

[0055] The part of the movable rod 56 that protrudes from the pressure rod 50 is also fitted with an elastic element 57. One end of the elastic element 57 abuts against the connecting part 60, and the other end of the elastic element 57 abuts against the pressure rod 50.

[0056] During the punching operation, firstly, the pressure rod 50 is lowered by the pneumatic structure described above. The pressure rod 50, along with the movable rod 56 and the auxiliary block 6, moves downwards together. When the pressure plate 61 contacts the working surface, the bottom end of the movable rod 56 cannot move further downwards. As the pressure rod 50 moves further downwards, the distance between the bottom end of the pressure rod 50 and the connecting part 60 decreases, and the portion of the upper end of the movable rod 56 extending beyond the pressure rod 50 becomes longer, compressing the elastic element 57. The elastic restoring force generated by the compression of the elastic element 57 acts on the auxiliary block 6, causing the pressure plate 61 to adhere tightly to the working surface, preventing displacement of the working surface during punching. Then, as the pressure rod 50 drives the punch rod 30 downwards until the punch 31 passes through the pressure plate 61 and contacts the working surface, the pressure rod 50 stops moving, the drive motor 12 starts, and the rotating sleeve 34 drives the punch rod 30 to rotate, thus performing the punching operation.

[0057] Furthermore, a blocking part 58 is fitted onto the part of the movable rod 56 that protrudes from the pressure rod 50, and the blocking part 58 is used to prevent the movable rod 56 from falling out of the pressure rod 50.

[0058] The blocking part 58 prevents the movable rod 56 from falling off the pressure rod 50 due to its own weight. Specifically, the blocking part 58 can be a nut fitted onto the top of the movable rod 56.

[0059] On the other hand, such as Figure 5 , Figure 7 and Figure 8 The auxiliary block 6 is also provided with a guide rod 63 that extends upward between the pressing plate 61 and the connecting part 60. The top of the guide rod 63 is provided with a navigation part 64. The part of the punch 30 located between the punch 31 and the rotating sleeve 34 is also provided with a guide sleeve 7. The guide sleeve 7 is provided with a navigation groove 70 that extends vertically. The navigation part 64 and the navigation groove 70 are slidably connected.

[0060] The navigation section 64 is slidably connected to the navigation groove 70 to form a guiding mechanism. This design ensures the stability of the relative position of the auxiliary block 6 and the punch 30, preventing the pressure plate 61 from shifting during operation and affecting the operation of the punch 31.

[0061] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
