Description

Technical Field

[0001] This utility model relates to the field of steel wire grating processing equipment, and in particular to a variable aperture steel wire grating stamping equipment. Background Technology

[0002] The joint strength (tensile, shear, tear, and torsion resistance) of the wire mesh should be high, and the joint force transmission performance of the longitudinal and transverse ribs of the mesh should be good, so that the force on the transverse ribs can be transmitted to the longitudinal ribs through the joints. It has a unique open structure and excellent quality characteristics. Wire mesh stamping refers to the process of processing steel wire material into a mesh shape through stamping. Specifically, stamping is the process of placing metal sheets, strips, pipes or profiles on a stamping machine, and using the mold on the stamping machine to apply external force to the material, causing it to separate or deform, thereby obtaining parts or products of the required shape and size.

[0003] Steel wire grating is widely used in many fields due to its advantages such as high strength, corrosion resistance, ventilation, and light transmission. In practical applications, different engineering scenarios have different requirements for the aperture size of steel wire grating. For example, in road protection, a larger aperture is needed to ensure visibility and ventilation, while in building safety nets, a smaller aperture is needed to improve the protective effect. Therefore, the ability to produce steel wire grating with variable aperture is of great practical significance. Traditional steel wire grating stamping equipment has some shortcomings, which restricts production efficiency and product quality. The stamping head structure of traditional equipment is fixed, and it can only stamp steel wire grating with a single aperture, which cannot meet the diverse market demand for steel wire grating with different apertures and limits the application range of the product. To address these issues, we propose a variable aperture steel wire grating stamping equipment. Utility Model Content

[0004] The purpose of this invention is to provide a variable aperture steel wire mesh stamping device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A variable aperture steel wire mesh stamping device includes a square frame. A clamping element is fixedly connected to the outer surface of the square frame. A hydraulic cylinder is fixedly connected to the upper surface of the square frame. A movable plate is fixedly connected to the output end of the hydraulic cylinder. A square cylinder is fixedly connected to the outer surface of the movable plate. Two sliding rods are fixedly connected to the inner wall of the square cylinder. A transmission slide is slidably connected to the outer surfaces of the two sliding rods. A main stamping head is fixedly connected to the bottom surface of the square cylinder. A secondary stamping head is slidably connected inside the main stamping head. The bottom end of the transmission slide is fixedly connected to the upper surface of the secondary stamping head. A moving screw is fixedly connected to the outer surface of the transmission slide. A locking nut is provided on the outer surface of the moving screw. A strip-shaped opening adapted to the locking nut is opened on the outer surface of the square cylinder. A square through-hole adapted to the transmission slide is opened on the bottom surface of the square cylinder. A through reinforcing rib is provided on the side wall of the main stamping head. A chamfered transition surface flush with the stamping end of the main stamping head is provided on the bottom surface of the secondary stamping head.

[0007] In a further embodiment, a bottom support plate is fixedly connected to the bottom surface of the square frame, and a mounting base with an opening is fixedly connected to the outer surface of the bottom support plate.

[0008] In a further embodiment, two square pads are fixedly connected to the upper surface of the bottom support plate.

[0009] In a further embodiment, a guide groove is provided on the upper surface of the bottom support plate, and a perforated lower mold frame is slidably connected inside the guide groove.

[0010] In a further embodiment, each of the clamping members includes a fixed frame that is fixedly installed on the outer surface of the square frame, an electric push rod is fixedly connected to the inner wall of each fixed frame, and a square pressure plate is fixedly connected to the output end of each electric push rod.

[0011] In a further embodiment, the inner wall of the square frame is fixedly connected to two guide rails, each guide rail has a slider slidably connected inside, and the outer surface of each slider is fixedly connected to the outer surface of the square tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device, by adjusting the moving screw and locking nut, can slide the transmission slide along the support rod, moving the auxiliary punch head.

This meets the market's demand for diverse hole diameters in wire mesh and improves product applicability. The electric push rod in the clamping component pushes the square pressure plate to firmly press the wire mesh, preventing mesh displacement during punching. The guide rail and slider ensure that the square cylinder, main punch head, and auxiliary punch head move vertically and smoothly during the punching process, improving punching accuracy.

[0021] 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.

[0022] Please see Figure 1-4In this utility model, a variable aperture steel wire mesh stamping device includes a square frame 1. A clamping member 2 is fixedly connected to the outer surface of the square frame 1. A hydraulic cylinder 6 is fixedly connected to the upper surface of the square frame 1. A moving plate 7 is fixedly connected to the output end of the hydraulic cylinder 6. A square cylinder 8 is fixedly connected to the outer surface of the moving plate 7. Two sliding rods 13 are fixedly connected to the inner wall of the square cylinder 8. A transmission slide block 14 is slidably connected to the outer surfaces of the two sliding rods 13. A main stamping head 16 is fixedly connected to the bottom surface of the square cylinder 8. A secondary stamping head 15 is slidably connected inside the main stamping head 16. The bottom end of the transmission slide block 14 is fixedly connected to the upper surface of the secondary stamping head 15. A moving screw is fixedly connected to the outer surface of the transmission slide block 14. 19. A locking nut 18 is provided on the outer surface of the moving screw 19. A strip-shaped opening 20 adapted to the locking nut 18 is opened on the outer surface of the square cylinder 8. A square through-hole 17 adapted to the transmission slide 14 is opened on the bottom surface of the square cylinder 8. The auxiliary punch head 15 is flush with the bottom of the main punch head 16. It is made of high-speed steel and tungsten steel, etc., and has good toughness. It forms the core structure of the variable aperture steel wire grid punching equipment, including punching, adjustment and guiding components. The square frame 1 provides support for the equipment. The hydraulic cylinder 6, moving plate 7, square cylinder 8, main punch head 16 and auxiliary punch head 15 realize the punching function. The transmission slide 14, moving screw 19 and locking nut 18 are used to adjust the punching. The aperture, support rod 13, and square opening 17 provide guidance and movement space for the transmission slide 14. When it is necessary to stamp wire mesh with different apertures, loosen the locking nut 18, adjust the position of the transmission slide 14 by moving the screw 19, and thus change the relative position between the auxiliary punch head 15 and the main punch head 16. After adjustment, tighten the locking nut 18 to fix it. The hydraulic cylinder 6 is an actuator that generates linear motion through hydraulic energy. The hydraulic cylinder 6 is usually composed of cylinder barrel, piston, piston rod, seals, and connecting parts. The hydraulic cylinder 6 generates thrust through the pressure of hydraulic oil, thereby realizing the linear motion of the working device. The side wall of the main punch head 16 is provided with through reinforcing ribs 21. The auxiliary punch head 15... The bottom surface of the press head 15 is provided with a chamfered transition surface 22 that is flush with the pressing end of the main press head 16. The radial reinforcing ribs 21 on the side wall of the main press head 16 are integrally formed from Q345B steel plate, which can disperse the lateral stress generated during the pressing. The bottom of the auxiliary press head 15 is machined with a 45° chamfered transition surface 22, and its cutting edge height maintains a precision tolerance of ±0.02mm with the main press head 16. When the auxiliary press head 15 moves to the target position, the chamfered transition surface 22 and the pressing end of the main press head 16 form a continuous curved surface, ensuring that the metal flow direction of the wire mesh is consistent during the pressing. The step height at the pressing joint is reduced from 0.5mm before the improvement to less than 0.1mm, which can meet the industrial-grade flatness requirements.

[0023] A bottom support plate 3 is fixedly connected to the bottom surface of the square frame 1. A mounting seat 4 with an opening is fixedly connected to the outer surface of the bottom support plate 3. The bottom support plate 3 provides a platform for placing the wire mesh. The mounting seat 4 with an opening facilitates the installation and fixation of the equipment, allowing the equipment to be placed stably on the work site and ensuring that the equipment will not shake or shift during the stamping process. Two square pads 5 are fixedly connected to the upper surface of the bottom support plate 3. The square pads 5 increase the contact area with the wire mesh, making the wire mesh more evenly stressed during stamping, avoiding deformation or damage to the mesh due to excessive local pressure, and improving product quality. A guide groove 11 is provided on the upper surface of the bottom support plate 3. A perforated lower die frame 12 is slidably connected inside the guide groove 11. The perforated lower die frame 12 has holes of different sizes on its surface. By simply sliding the perforated lower die frame 12 in the guide groove 11, it can cooperate with the auxiliary stamping head 15 and the main stamping head 16 for stamping, adapting to different stamping requirements and improving production flexibility and efficiency.

[0024] Each clamping component 2 includes a fixed frame 201 fixedly installed on the outer surface of the square frame 1. An electric push rod 202 is fixedly connected to the inner wall of each fixed frame 201. A square pressure plate 203 is fixedly connected to the output end of each electric push rod 202. The fixed frame 201, electric push rod 202 and square pressure plate 203 of the clamping component 2 work together. The electric push rod 202 pushes the square pressure plate 203 to firmly clamp the wire mesh, preventing the mesh from shifting during stamping and ensuring stamping accuracy. Two guide rails 9 are fixedly connected to the inner wall of the square frame 1. A slider 10 is slidably connected inside each guide rail 9. The outer surface of each slider 10 is fixedly connected to the outer surface of the square cylinder 8. The guide rails 9 and sliders 10 provide stable guidance for the movement of the square cylinder 8, ensuring that the square cylinder 8, the main stamping head 16 and the auxiliary stamping head 15 move vertically and smoothly during the stamping process, avoiding the stamping head tilting and improving stamping accuracy.

[0025] The working principle of this utility model is as follows:

[0026] The wire mesh is placed on the bottom support plate 3, and the square pad 5 is in direct contact with the wire mesh. When it is necessary to punch wire mesh with different hole diameters, the locking nut 18 is loosened, and the position of the transmission slide 14 is adjusted by moving the screw 19, so that the transmission slide 14 slides along the support rod 13, thereby changing the relative position between the auxiliary punch head 15 and the main punch head 16. After adjustment, the locking nut 18 is tightened to fix it. Then, the clamping part 2 and the hydraulic cylinder 6 are started. The electric push rod 202 pushes the square pressure plate 203 to press the wire mesh on the square pad 5. The perforated lower die frame 12 moves in the guide groove 11, moving the corresponding hole position to below the auxiliary punch head 15 and the main punch head 16. Finally, the hydraulic cylinder 6 drives the moving plate 7 and the square cylinder 8 to descend. The main punch head 16 and the auxiliary punch head 15 punch the wire mesh to obtain the wire mesh with the required hole diameter.
