Description

Technical Field

[0001] This utility model relates to the field of door and window processing, specifically to a continuous punching device for door and window panels. Background Technology

[0002] Door and window processing is a crucial step in building decoration, encompassing design, material selection, cutting, assembly, and surface treatment. Precise measurement and cutting ensure accurate profile dimensions; welding and corner assembly techniques guarantee structural stability; and surface treatments such as oxidation and spraying enhance the corrosion resistance and aesthetics of the doors and windows. Punching devices are required during the processing of door and window panels.

[0003] Existing punching equipment cannot effectively limit and fix the sheet metal during punching operations, which can easily cause the sheet metal to shift, resulting in hole position displacement or hole diameter deformation, affecting processing accuracy.

[0004] Furthermore, waste from traditional punching processes spills into gaps in the workbench or on the floor, requiring frequent manual cleaning. This not only reduces production efficiency but also poses operational safety hazards. Waste accumulation can also affect equipment operational stability, increase maintenance costs, and raise the risk of production interruptions.

[0005] Therefore, we have made improvements to this by proposing a continuous punching device for door and window panels. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a continuous punching device for door and window panels, which solves the problems mentioned in the background art.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] A continuous punching device for door and window panels is used to solve the above problems.

[0009] The application is as follows:

[0010] The device includes an operating platform, on the upper surface of which a column is fixedly installed, and on the upper surface of the column a drive box is fixedly installed. A punching mechanism is provided on the lower side of the drive box, and two sets of fixing mechanisms are provided on the surface of the punching mechanism. An operating plate is fixedly installed on the upper surface of the operating platform, and a punching hole is provided in the middle of the operating plate. Limiting mechanisms are provided on both sides of the operating plate.

[0011] The punching mechanism includes a sliding rod, which is slidably connected to the bottom of the drive box. A lifting plate is fixedly installed on the lower surface of the sliding rod, and a punching head is fixedly installed in the middle of the lower surface of the lifting plate. Four limit rods are fixedly installed between the operating table and the drive box, and the lifting plate and the limit rods are connected by a sliding connection.

[0012] As a preferred technical solution of this application, a mounting plate is fixedly installed on the top of the drive box, and a motor is fixedly installed on one side surface of the mounting plate. A rotating disk is fixedly installed on the output end of the motor, and a connecting rod is rotatably connected to the outer side of the rotating disk surface. The connection between the lower end of the connecting rod and the sliding rod is a hinged connection.

[0013] As a preferred technical solution of this application, the fixing mechanism includes fixing rods, and there are two fixing rods. The two fixing rods are fixedly installed on the lower surface of the lifting plate. The lower ends of the two fixing rods are slidably connected to pressure plates, and rubber pads are fixedly installed on the lower surface of the pressure plates. Springs are sleeved on the outside of the fixing rods, and the springs are fixedly installed between the lifting plate and the pressure plates.

[0014] As a preferred technical solution of this application, a limiting block is fixedly installed on the lower end surface of the fixing rod, a limiting groove is opened inside the pressure plate, and the limiting block is slidably connected in the limiting groove.

[0015] As a preferred technical solution of this application, the limiting mechanism includes a fixed plate, and a threaded rod is threadedly connected to the middle of the fixed plate. One end of the threaded rod is bearing-connected to a movable plate, and the movable plate is slidably connected to the surface of the operating table. Both ends of the movable plate are fixedly installed with L-shaped limiting plates, and the other end of the threaded rod is fixedly installed with a knob.

[0016] As a preferred technical solution of this application, the punching hole penetrates through the top of the operating table, a collection frame is slidably connected inside the operating table, and a handle is fixedly installed on one side surface of the collection frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In the scheme of this application:

[0019] 1. By using a fixing mechanism and a limiting mechanism, the pressing plate of the stamping press causes the spring to deform, and the rubber pad increases the friction of the contact surface, forming a stable pre-pressing zone. Together with the L-shaped limiting plate of the limiting mechanism, the sheet metal is precisely positioned laterally. The two work together to suppress the instantaneous movement and vibration of the stamping, ensuring that the sheet metal maintains the predetermined position throughout the punching process, significantly improving the hole position accuracy and processing consistency, effectively reducing the scrap rate caused by displacement, and ensuring the stability of production quality.

[0020] 2. By using punching holes and a collection frame, punching waste falls directly into the bottom collection frame through the punching holes that pass through the operating table, forming a vertical closed collection path. This prevents waste from scattering into equipment gaps or on the ground, reducing the frequency of manual cleaning and operational risks. The collection frame is equipped with a handle for quick and easy cleaning. Combined with the straight-through structure of the punching holes, it achieves centralized storage and efficient transfer of waste, improving production continuity and safety, and reducing equipment maintenance costs and the risk of production interruption.

[0033] To address the technical problems in the background section, the following continuous punching device for door and window panels is provided:

[0034] Combination Figure 1 - Figure 5 As shown, the present invention provides a continuous punching device for door and window panels, including an operating table 1, a column 2 fixedly installed on the upper surface of the operating table 1, a drive box 3 fixedly installed on the upper surface of the column 2, a punching mechanism 4 provided on the lower side of the drive box 3, and two sets of fixing mechanisms 5 provided on the surface of the punching mechanism 4. An operating plate 6 is fixedly installed on the upper surface of the operating table 1, and a punching hole 7 is opened in the middle of the operating plate 6. Limiting mechanisms 8 are provided on both sides of the operating plate 6. The punching mechanism 4 includes a sliding rod 401, and the sliding rod 401 is slidably connected to the bottom of the drive box 3. A lifting plate 402 is fixedly installed on the lower surface of the sliding rod 401, and a punching head 403 is fixedly installed in the middle of the lower surface of the lifting plate 402. Four limiting rods 404 are fixedly installed between the operating table 1 and the drive box 3, and the lifting plate 402 and the limiting rods 404 are connected by a sliding connection.

[0035] In this embodiment, the punching mechanism 4 utilizes the sliding engagement between the sliding rod 401 and the bottom of the drive box 3, as well as the guiding structure of the lifting plate 402 and the four limiting rods 404, to achieve the vertical lifting movement of the punching head 403 for punching operations. During operation, the fixing mechanism 5 can fix the punched sheet metal, and the limiting mechanism 8 can effectively limit the sheet metal before processing, preventing the sheet metal from shifting during the punching process, ensuring punching accuracy and processing stability, and significantly improving the product qualification rate. The punching hole 7 on the operation plate 6 and the bottom collection frame 9 form a waste discharge channel, facilitating waste collection.

[0036] In a preferred embodiment, a mounting plate 405 is fixedly installed on the top of the drive box 3, and a motor 406 is fixedly installed on one side surface of the mounting plate 405. A rotating disk 407 is fixedly installed at the output end of the motor 406, and a connecting rod 408 is rotatably connected to the outer side of the surface of the rotating disk 407. The lower end of the connecting rod 408 is connected to the sliding rod 401 by a hinge connection.

[0037] In this embodiment: the motor 406 is fixed in the drive box 3 by the mounting plate 405. When the motor 406 drives the rotating disk 407 to rotate, the connecting rod 408 swings back and forth along the outer trajectory of the rotating disk 407. The rotational motion is converted into the vertical linear motion of the sliding rod 401 through the hinge structure, thereby driving the punch head 403 to achieve high-frequency and stable continuous punching action, ensuring processing efficiency and punching quality.

[0038] In a preferred embodiment, the fixing mechanism 5 includes two fixing rods 501, which are fixedly installed on the lower surface of the lifting plate 402. The lower ends of the two fixing rods 501 are slidably connected to a pressure plate 502, and a rubber pad 503 is fixedly installed on the lower surface of the pressure plate 502. A spring 504 is sleeved on the outside of the fixing rods 501, and the spring 504 is fixedly installed between the lifting plate 402 and the pressure plate 502.

[0039] In this embodiment: when the punch head 403 moves downward, the rubber pad 503 on the lower surface of the pressure plate 502 will first contact the plate. The elastic buffering effect of the spring 504 will make the pressure plate 502 press the plate surface with uniform pressure. The flexible contact of the rubber pad 503 can also avoid scratches on the plate surface, effectively prevent the plate from sliding or shifting due to uneven force during punching, ensure the punching position, and avoid punching burrs or dimensional deviations caused by plate shaking.

[0040] In a preferred embodiment, a limiting block 505 is fixedly installed on the lower end surface of the fixing rod 501, a limiting groove 506 is formed inside the pressure plate 502, and the limiting block 505 is slidably connected in the limiting groove 506.

[0041] In this embodiment, the limiting block 505 moves vertically within the limiting groove 506, which can effectively constrain the travel range of the pressure plate 502 and prevent the pressure plate 502 from detaching from the fixing rod 501.

[0042] In a preferred embodiment, the limiting mechanism 8 includes a fixed plate 801, and a threaded rod 802 is threadedly connected to the middle of the fixed plate 801. A movable plate 803 is bearing-connected to one end of the threaded rod 802, and the movable plate 803 is slidably connected to the surface of the operating table 1. L-shaped limiting plates 804 are fixedly installed on both ends of the movable plate 803, and a knob 805 is fixedly installed on the other end of the threaded rod 802.

[0043] In this embodiment: the limiting mechanism 8 drives the threaded rod 802 to rotate by rotating the knob 805, so that the moving plate 803, which is threadedly connected to the fixed plate 801, moves precisely laterally along the surface of the operating table 1, thereby driving the L-shaped limiting plates 804 at both ends to move for adjustment. By adjusting the two L-shaped limiting plates 804 on both sides, the limiting of plates of different widths is achieved, ensuring that the plate always maintains a proper position during the stamping process, effectively avoiding punching errors caused by offset.

[0044] In a preferred embodiment, the punching hole 7 penetrates the top of the operating table 1, and a collection frame 9 is slidably connected inside the operating table 1, with a handle 10 fixedly installed on one side surface of the collection frame 9.

[0045] In this embodiment, the punching hole 7 penetrates the top of the operating table 1, allowing the waste generated during the punching process to fall directly into the operating table 1. The slidingly connected collection frame 9 can accurately receive this waste. With the handle 10 fixedly installed on one side of the frame, it is convenient for operators to quickly pull out the collection frame 9 to clean up the waste, effectively keeping the work area clean and preventing the accumulation of waste from affecting the normal operation of the equipment, thus improving the overall ease of use and maintenance efficiency.

[0046] Specifically, the working principle of this solution is as follows:

[0047] When using the device, first adjust the limit mechanism 8 according to the width of the sheet material. Rotate the knob 805 to drive the threaded rod 802 fixed to it to rotate around the axis. Since the threaded rod 802 is threadedly connected to the fixed plate 801, its rotational motion is converted into the transverse linear motion of the moving plate 803 along the surface of the operating table 1. The moving plate 803 drives the L-shaped limit plates 804 fixed at both ends to move synchronously, adjusting to match the width of the sheet material, thus achieving sheet material limitation.

[0048] Next, the motor 406 inside the drive box 3 is started, driving the rotating disk 407 to perform circular motion. The connecting rod 408 on the outside of the rotating disk 407 reciprocates with its rotation, and the rotational motion is converted into the vertical linear motion of the sliding rod 401 at the bottom of the drive box 3 through the hinge structure. The sliding rod 401 drives the lifting plate 402 to slide down along the four limit rods 404, causing the stamping head 403 to move downward to stamp the sheet metal.

[0049] As the stamping head 403 descends, the fixing rods 501, which are fixed to both sides of the lower surface of the lifting plate 402, move downwards accordingly. The pressure plate 502, which is slidably connected at its lower end, contacts the sheet material first. The rubber pad 503 makes flexible contact with the sheet material to avoid scratches, and the spring 504 is compressed to generate elastic buffering force, so that the pressure plate 502 presses the sheet material evenly and prevents it from sliding or shifting.

[0050] Punching waste falls through the punching holes 7 of the operating plate 6 into the collection box 9 inside the operating table 1. The operator can quickly pull out the collection box 9 using the handle 10 to clean up the waste and keep the work area clean. The various mechanisms work together to achieve efficient and precise punching processing.

[0051] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0052] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
