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.
[0026] Reference Figures 1-6This utility model provides an embodiment of a sheet metal bending and punching device, comprising a base 1, which serves as the basic support structure for supporting other components. A top frame 2 is fixedly connected to the top of the base 1, and a hydraulic cylinder 3 is fixedly installed at the center of the top of the top of the top frame 2. A mounting plate 4 is fixedly connected to the output end of the hydraulic cylinder 3. The hydraulic cylinder 3 serves as a power source and can drive the mounting plate 4 to move up and down through the extension and retraction of its output end. An upper die head 5 is fixedly installed at the center of the bottom of the mounting plate 4 for bending, punching, and cutting sheet metal. A lower die head 6 is fixedly installed at the center of the top of the base 1. The lower die head 6 serves as a support base for sheet metal processing and has processing tools on its surface corresponding to those on the upper die head 5. A support 9 is fixedly connected to one side of the top of the base 1. Connecting seats 16 are installed on both sides of the top of the support 9. Two guide wheels 17 are fixedly installed on the surface of each connecting seat 16. The guide wheels 17 are arranged in pairs and achieve feed guidance by rolling contact with both sides of the sheet metal. An adjustment component is installed inside the support 9. The adjustment component is used to drive the connecting seats 16 to move to adapt to sheet metal of different widths. A receiving component is installed at the top of the inner wall of the base 1. The receiving component is used to collect the round waste generated by punching and keep the device clean. A discharge port 19 is opened at the top of the base 1 corresponding to the lower die head 6. The discharge port 19 is connected to the waste channel of the lower die head 6 so that the waste falls into the receiving component.
[0027] Reference Figure 2 The receiving assembly includes two guide rails 20 and a receiving frame 21. The two guide rails 20 are fixedly connected to the two sides of the top of the inner wall of the base 1. The receiving frame 21 is inserted into the inner wall of the two guide rails 20. The guide rails 20 provide sliding tracks for the receiving frame 21, which facilitates installation and disassembly. The receiving frame 21 is used to collect waste materials in a centralized manner.
[0028] Reference Figures 3-5 The adjustment assembly includes a geared motor 10, a gear 11, two racks 12, two sliding components, and two support blocks 15. The geared motor 10 is fixedly installed at the bottom of the support 9. The geared motor 10 provides power and increases torque by reducing the speed to ensure a smooth adjustment process. The output end of the geared motor 10 is fixedly connected to the gear 11 through the inner wall of the support 9. The two sliding components are respectively installed on both sides of the inner wall of the machine base. Each side of the two sliding components is connected to a rack 12. The sliding components provide sliding support and guidance for the rack 12 to ensure movement accuracy. The two sides of the gear 11 mesh with the two racks 12 respectively, converting the rotational motion of the motor into the linear motion of the rack 12. A support block 15 is fixedly connected to one side of the top of the rack 12, and the top of the support block 15 is fixedly connected to the connecting seat 16. Through the connection of the support block 15, the movement of the rack 12 directly drives the connecting seat 16 to move synchronously.
[0029] Reference Figure 5The sliding assembly includes an inner slide rail 14 and an outer slide rail 13. The inner slide rail 14 is fixedly connected to one side of the inner wall of the support 9. The outer slide rail 13 is slidably connected to the surface of the inner slide rail 14, and the rack 12 is fixedly connected to one side of the outer slide rail 13. The outer slide rail 13 can slide along the inner slide rail 14 and can drive the rack 12 to move, thus providing support and guidance for the rack 12.
[0030] Reference Figure 6 Magnets 22 are fixedly embedded at one end of the top two sides of the receiving frame 21 and at one end of the two guide rails 20. The magnets 22 connect the receiving frame 21 to the end of the guide rails 20 through magnetic attraction, with opposite poles attracting each other, to prevent shaking during operation.
[0031] Reference Figure 2 Guide posts 7 are inserted and connected to the four corners of the mounting plate 4. The top of the guide post 7 is fixedly connected to the top of the inner wall of the top frame 2, and the bottom of the guide post 7 is fixedly connected to the top of the base 1. The guide post 7 provides guidance for the up and down movement of the mounting plate 4, ensuring that the upper mold head 5 and the lower mold head 6 are aligned.
[0032] Reference Figure 2 A buffer spring 8 is fitted at the bottom of the guide column 7, and the bottom end of the buffer spring 8 is fixedly connected to the base 1. The buffer spring 8 is used to absorb the impact force when the mounting plate 4 moves down, reduce vibration and protect the equipment.
[0033] Reference Figure 3 and Figure 5 Displacement openings 18 are provided on both sides of the top of the support 9, and the support block 15 is slidably connected to the inner wall of the displacement opening 18. The displacement opening 18 provides a channel for the movement of the support block 15, so that the connecting seat 16 can slide laterally along the top surface of the support 9.
[0034] Reference Figure 1 The top of the mounting base and the top of the lower die head 6 are on the same horizontal plane to ensure that the sheet metal plate smoothly transitions from the support 9 to the lower die head 6, avoiding the plate getting stuck during processing.
[0035] Working principle: The sheet metal to be processed is inserted through the side of the top frame 2, with one end placed on the lower die head 6 via the support 9. The gear 11 is rotated by starting the reduction motor 10. Supported and guided by the inner and outer slide rails, this causes the racks 12 on both sides to move in opposite directions. This, in turn, causes the connecting seats 16 on both sides to move in opposite directions via the support block 15. The spacing of the guide wheels 17 on both sides is adjusted to accommodate sheet metal of different widths, preventing bending and punching misalignment. The hydraulic cylinder 3 is activated to move the mounting plate 4 and the upper die head 5 downwards. The lower die head 6 can bend, punch, and cut sheet metal to form sheet metal parts. After being removed, the sheet metal is pushed forward again for repeated operation. The round waste generated during the punching of the sheet metal will fall into the receiving frame 21 at the bottom of the device through the channel on the lower die head 6 and the material drop port 19 for collection. The receiving frame 21 is attached to the guide rail 20 by the cooperation of the magnet 22 to maintain stability. After a certain amount of round pieces are collected, the receiving frame 21 can be removed and poured out. This can effectively collect the round waste during punching and avoid accumulation and blockage that affects normal punching work.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
