Description
Technical Field
[0001] This utility model belongs to the field of fire door production, specifically, it relates to a punch press for fire door production. Background Technology
[0002] Fire doors, in the metal processing industry, are large and heavy sheet metal components, and their production typically involves multiple processes such as drilling, pressing, and forming. Punching is an essential step, and its quality directly affects the installation accuracy of subsequent components like locks and hinges. However, most existing punching machines are designed for general sheet metal, and for workpieces like fire doors that are wide, long, and have easily deformable surfaces, stable positioning and clamping are often difficult to achieve. Traditional methods rely on fixed blocks or manual pressure plates for positioning, but this requires frequent adjustments for fire doors of different sizes, is time-consuming, and involves high levels of manual intervention. Furthermore, vibrations during punching can easily cause displacement, leading to hole misalignment, rough holes, or even punch damage.
[0003] Furthermore, due to the large area and limited rigidity of fire door panels, the instantaneous impact applied by the punch during stamping can cause slight warping or bouncing in localized areas. When the panel is not sufficiently compressed, this minute deformation directly affects the stability of the punched hole position. While existing equipment uses mechanical clamps for auxiliary fixing in some areas, these clamps are mostly single-sided adjustable or have simple structures, making it impossible to achieve uniform and reliable clamping on large panels, especially prone to inaccurate positioning or insufficient clamping force along the long side.
[0004] In view of this, this utility model is proposed. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a punch press for fire door production, which solves the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A punch press for manufacturing fire doors includes: a punch press body, a mounting plate fixedly connected to the top of the punch press body, a placement mechanism fixedly connected to the top of the mounting plate, and a fire door body placed on the top of the placement mechanism. The placement mechanism includes a placement frame, with clamping components for clamping the fire door body slidably connected to both sides of the placement frame. A hydraulic cylinder is fixedly connected to one side of the punch press body, and a punching head is fixedly connected to the output end of the hydraulic cylinder. A through hole adapted to the punching head is opened on the top of the placement frame. The inside of the placement frame is slidably connected to a collection box for collecting waste. Several grooves are provided on the top of the placement frame, and electromagnets are connected inside the grooves.
[0007] Optionally, the clamping assembly includes a sliding frame slidably connected to one side of the placement frame, with two clamping rods slidably connected above the sliding frame.
[0008] Optionally, a slider that slides inside a sliding frame is connected to the lower part of the clamping rod, and a screw is rotatably connected inside the sliding frame. A threaded hole that matches the screw is opened through the opposite side of the slider.
[0009] Optionally, a servo motor is fixedly connected to one side of the sliding frame, and the output end of the servo motor is fixedly connected between the sliding frame and the screw, with the thread directions of the two ends of the screw being opposite.
[0010] Optionally, a side plate is fixedly connected to one side of the placement frame, an electric push rod is fixedly connected to one side of the side plate, a connecting plate is fixedly connected to the lower side of the sliding frame, and the output end of the electric push rod is fixedly connected to the connecting plate.
[0011] Optionally, a magnetic piece is fixedly connected to one side of the collection box, and the magnetic piece and the sliding frame are magnetically connected.
[0012] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time: This invention utilizes adjustable clamping components on both sides of the placement frame to quickly clamp fire door panels after placement. Different door sizes can be stably positioned by adjusting the clamping rod positions, preventing displacement during stamping and ensuring accurate hole positioning. Simultaneously, several grooves are provided above the placement frame, and electromagnets are installed within these grooves. During stamping, the electromagnets provide additional attraction to the metal sheet, ensuring the sheet remains in a close fit even under impact, effectively reducing vibration and warping. The mechanical clamping and electromagnetic attraction of the clamping components work together to keep the sheet reliably controlled within the stamping area, improving processing stability, reducing scrap rates, and enhancing safety and consistency during continuous production.

Detailed Implementation
[0017] The present invention will now be described in further detail with reference to the accompanying drawings.
[0018] Please see Figure 1-5 As shown, this embodiment provides a punch press for fire door production, including a punch press body 1, a mounting plate 2 fixedly connected to the top of the punch press body 1, a placement mechanism fixedly connected to the top of the mounting plate 2, and a fire door body 3 placed on top of the placement mechanism. The placement mechanism includes a placement frame 4, with clamping components for clamping the fire door body 3 slidably connected to both sides of the placement frame 4. A hydraulic cylinder 5 is fixedly connected to one side of the punch press body 1, and a punching head 6 is fixedly connected to the output end of the hydraulic cylinder 5. A through hole 7 adapted to the punching head 6 is opened on the top of the placement frame 4. The placement frame 4 has a sliding connection to a collection box 8 for collecting waste. Several grooves are provided on the top of the placement frame 4, and electromagnets 9 are connected inside the grooves.
[0019] This invention improves punching accuracy and consistency by installing a placement mechanism above the punch press body 1 and using a clamping assembly to stably clamp the fire door body 3, ensuring the fire door remains in a consistent position during the punching process. The collection box 8 inside the placement frame 4 catches falling waste material during punching, preventing it from scattering and affecting the working environment, and reducing subsequent cleaning time. The electromagnet 9 above the placement frame 4 assists in fixing the fire door panel during punching, further enhancing punching stability and reducing vibration-induced errors. The overall structure provides the punch press with high positioning accuracy, high safety, and high production efficiency during the processing of large-size fire door panels.
[0020] In this embodiment, the clamping assembly includes a sliding frame 10 slidably connected to one side of the placement frame 4, and two clamping rods 11 slidably connected above the sliding frame 10. By providing sliding frames 10 on both sides of the placement frame 4 and slidably connecting two clamping rods 11 above the sliding frames 10, the clamping assembly can adaptively adjust the clamping position according to the different widths of the fire door panels, thereby improving the flexibility of clamping. The clamping rod 11 structure ensures that the clamping force acts on the side of the fire door, preventing damage or scratches to the door panel surface and guaranteeing the product's appearance quality.
[0021] In this embodiment, a slider 12 that slides inside a sliding frame 10 is connected below the clamping rod 11. A screw 13 is rotatably connected inside the sliding frame 10, and a threaded hole adapted to the screw 13 is provided on the opposite side of the slider 12. The slider 12 is positioned below the clamping rod 11 and slides inside the sliding frame 10. At the same time, the internal screw 13 drives the slider 12 to move precisely through the threaded hole, giving the opening and closing action of the clamping rod 11 a high-precision adjustment capability. Because the threaded drive has a self-locking property, the clamping rod 11 is not easily loosened due to vibration after clamping, thereby ensuring that the fire door body 3 remains stable during the stamping process. In this embodiment, a servo motor 14 is fixedly connected to one side of the sliding frame 10. The output end of the servo motor 14 passes through the sliding frame 10 and is fixedly connected to the screw 13, and the threads at both ends of the screw 13 are in opposite directions. By setting the servo motor 14 on one side of the sliding frame 10 and using the servo motor 14 to drive the screw 13 with opposite thread directions at both ends, the sliders 12 on both sides can achieve symmetrical opening and closing adjustment, so that the clamping rod 11 always remains synchronized when clamping or releasing.
[0022] In this embodiment, a side plate 15 is fixedly connected to one side of the placement frame 4, and an electric push rod 16 is fixedly connected to one side of the side plate 15. A connecting plate 17 is fixedly connected to the lower side of the sliding frame 10, and the output end of the electric push rod 16 is fixedly connected to the connecting plate 17. The electric push rod 16 can be used to adjust the position of the fire door, thereby achieving the effect of punching holes at different positions.
[0023] In this embodiment, a magnet 18 is fixedly connected to one side of the collection box 8, and the magnet 18 and the sliding frame 10 are magnetically connected. The magnet 18 on one side of the collection box 8 and its magnetic connection to the sliding frame 10 allow the collection box 8 to be quickly disassembled or installed when needed, and the connection is secure and does not loosen, facilitating timely waste removal by operators.
