Abstract
Description
Technical Field
[0001] This utility model relates to the field of planar wire drawing technology, and in particular to an automatic wire drawing machine for the production of security doors. Background Technology
[0002] In the production of security doors, surface treatment technology is crucial for enhancing product texture, increasing durability, and meeting diverse aesthetic demands. Wire drawing machines, as an important piece of equipment in the field of metal surface treatment, play an irreplaceable role in the surface treatment of metal materials such as stainless steel, aluminum alloys, and copper due to their high efficiency and precision. Wire drawing machines primarily use a drawing wheel (or grinding wheel) to contact the workpiece surface, utilizing the friction generated by high-speed rotation to form continuous, uniform filamentary textures on the metal surface.
[0003] In existing technologies, the force applied during the wire drawing process of metal sheets required for security door production directly affects the stability and accuracy of the processing results. For example, when drawing aluminum sheets, the greater the drawing pressure, the deeper the texture, but excessive pressure may lead to material deformation, breakage, or a decrease in surface quality. Therefore, we propose an automatic wire drawing machine for security door production to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an automatic wire drawing machine for the production of security doors.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An automatic wire drawing machine for producing security doors includes a conveyor frame with multiple electric rollers rotatably connected inside. Two water-blocking vertical plates are fixedly connected inside the conveyor frame. A sewage collection tank is placed at the bottom of the conveyor frame. Multiple drainage holes are formed on the outer bottom wall of the conveyor frame. An equipment frame is fixedly connected to the top of the conveyor frame. A water replenishment assembly is provided inside the conveyor frame. An electric push rod is fixedly connected to the top of the equipment frame. A lower pressure plate is fixedly connected to the bottom of the output end of the electric push rod. Four through holes are formed on the outer wall of the lower pressure plate. Sliding rods are slidably connected to the inner walls of the four through holes. First springs are sleeved on the outer walls of the four sliding rods. Nuts are threaded onto the tops of the four sliding rods. A common mounting bracket is fixedly connected to the bottom of the four sliding rods. Two second springs are fixedly connected to the top of the mounting bracket. Two pressure sensors are fixedly embedded in the bottom of the lower pressure plate. The detection ends of the pressure sensors are fixedly connected to the tops of the second springs. A wire drawing assembly is provided at the bottom of the mounting bracket.
[0007] Preferably, the water replenishment component includes a water replenishment pipe, and the outer wall of the equipment frame has an installation hole. The inner wall of the installation hole is fixedly connected to the outer wall of the water replenishment pipe. Multiple atomizing nozzles are fixedly interconnected on the outer wall of the water replenishment pipe, and a water pump is fixedly interconnected at one end of the water replenishment pipe. By setting the water replenishment component to spray water mist onto the metal sheet, the frictional heat of subsequent processing can be effectively reduced.
[0008] Preferably, the wire drawing assembly includes two motors, the outer walls of the two motors are fixedly connected to the outer wall of the mounting frame, and one end of the output shaft of each motor passes through the outer wall of the mounting frame and is fixedly connected to a wire drawing roller. The wire drawing roller is made of existing wire drawing wheel material, such as nylon.
[0009] Preferably, two U-shaped frames are fixedly connected to the bottom of the conveying frame to support it.
[0010] Preferably, the top of the device frame is provided with a sliding hole, and the inner wall of the sliding hole is slidably connected to the outer wall of the output end of the electric push rod. The electric push rod drives the lower pressure plate and the mounting frame to rise and fall.
[0011] Preferably, the top of the first spring contacts the bottom of the lower pressure plate, and the bottom of the first spring contacts the top of the mounting bracket. After the mounting bracket contacts the metal sheet, the mounting bracket moves upward via four sliding rods, while the four first springs are compressed.
[0012] Preferably, one end of the drawing roller is rotatably connected to the outer wall of the mounting frame.
[0013] Compared with the prior art, the advantages of this utility model are:
[0014] In this solution, water mist is sprayed onto the metal sheet through a water pump and atomizing nozzle during the wire drawing process. Wet wire drawing can effectively reduce frictional heat, prevent the material from overheating and deforming, and also improve the smoothness and quality of the wire drawing surface.
[0015] Through feedback from pressure sensors and the buffering effect of springs, the equipment can adapt to metal sheets of different materials and thicknesses. Whether it is aluminum sheet or other metal materials, the ideal processing effect can be achieved by adjusting the wire drawing force. It can realize automatic feeding and wire drawing of metal sheets, reduce errors caused by human operation, and ensure the stability of the processing process. Attached Figure Description

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Depend on Figures 1-4 As shown, an automatic wire drawing machine for producing security doors is disclosed, comprising a conveyor frame 1, with multiple electric rollers 2 rotatably connected inside the conveyor frame 1, two U-shaped frames 3 fixedly connected to the bottom of the conveyor frame 1, two water-blocking vertical plates 4 fixedly connected inside the conveyor frame 1, a sewage collection tank 6 placed at the bottom of the conveyor frame 1, and multiple drainage holes 5 opened on the bottom outer wall of the conveyor frame 1. During the wet wire drawing process, sewage flows downward along the multiple electric rollers 2 and the conveyor frame 1, while the two water-blocking vertical plates 4 prevent sewage from flowing out from both ends of the conveyor frame 1, causing it to be discharged downward through the multiple drainage holes 5 and fall into the sewage collection tank 6.
[0024] A device frame 7 is fixedly connected to the top of the conveyor frame 1. An electric push rod 10 is fixedly connected to the top of the device frame 7. A sliding hole is opened on the top of the device frame 7. The inner wall of the sliding hole is slidably connected to the outer wall of the output end of the electric push rod 10. A lower pressure plate 11 is fixedly connected to the bottom of the output end of the electric push rod 10. Four through holes are opened on the outer wall of the lower pressure plate 11. A slide rod 12 is slidably connected to the inner wall of each of the four through holes. A first spring 13 is sleeved on the outer wall of each of the four slide rods 12. A nut 14 is threaded on the top of each of the four slide rods 12. The same mounting bracket 15 is fixedly connected to the bottom of the four slide rods 12. The top of the first spring 13 is in contact with the bottom of the lower pressure plate 11, and the bottom of the first spring 13 is in contact with the top of the mounting bracket 15. The first spring 13 plays a buffering role during the pressing process of the wire drawing roller 18 to prevent sudden pressure changes from damaging the metal sheet. At the same time, the elasticity detection of the second spring 16 further ensures the precise control of the extrusion pressure.
[0025] Two second springs 16 are fixedly connected to the top of the mounting bracket 15, and two pressure sensors 17 (Super-TE) are fixedly embedded in the bottom of the lower pressure plate 11. The detection end of the pressure sensor 17 (Super-TE) is fixedly connected to the top of the second spring 16.
[0026] The pressure sensor 17 (Super-TE) detects the compression force of the second spring 16 in real time and transmits the data to the controller. The controller determines whether the current extrusion force is too large based on the preset pressure threshold. If the extrusion force exceeds the set value, the controller can adjust the stroke of the electric push rod 10 or stop pressing down, thereby avoiding the wire drawing roller 18 from applying excessive extrusion force to the metal sheet.
[0027] The inside of the conveying frame 1 is equipped with a water replenishment component, which includes a water replenishment pipe 8. The outer wall of the equipment frame 7 is provided with an installation hole. The inner wall of the installation hole is fixedly connected to the outer wall of the water replenishment pipe 8. Multiple atomizing nozzles 9 are fixedly connected to the outer wall of the water replenishment pipe 8. The multiple atomizing nozzles 9 are set downwards. A water pump is fixedly connected to one end of the water replenishment pipe 8.
[0028] The bottom of the mounting frame 15 is provided with a wire drawing assembly, which includes two motors 19. The outer walls of the two motors 19 are fixedly connected to the outer wall of the mounting frame 15. One end of the output shaft of each of the two motors 19 passes through the outer wall of the mounting frame 15 and is fixedly connected to a wire drawing roller 18. One end of the wire drawing roller 18 is rotatably connected to the outer wall of the mounting frame 15. An existing bearing is fixedly fitted on one end of the wire drawing roller 18. The outer ring of the bearing is fixedly connected to the outer wall of the mounting frame 15. During the downward pressing of the wire drawing roller 18, the first spring 13 and the second spring 16 are compressed. Since the elastic coefficients of the first spring 13 and the second spring 16 are the same, the compression force of the second spring 16 can directly reflect the compression force of the first spring 13, and thus reflect the extrusion force between the wire drawing roller 18 and the metal sheet.
[0029] Working Principle: During operation, the metal sheet material for making the security door is placed in the conveyor frame 1, located on top of multiple electric rollers 2 on the left side of the equipment frame 7. The electric rollers 2 convey the material to the right, allowing it to slowly enter the equipment frame 7. When wet wire drawing is required, a water pump draws external water into the water supply pipe 8, which is then sprayed downwards by multiple atomizing nozzles 9, misting the outer surface of the metal sheet. The electric push rod 10 moves the lower pressure plate 11 downwards, which in turn moves the mounting frame 15 downwards via four sliding rods 12. The downward movement of the mounting frame 15 then moves two motors 19 and two wire drawing rollers 18 downwards. The two motors 19 then drive the two wire drawing rollers 18 to perform the wire drawing process. When the metal sheet comes into contact with the outer wall of the drawing roller 18, the top of the metal material is drawn by the rotation of the drawing roller 18. After the mounting bracket 15 moves downward, the two drawing rollers 18 exert downward pressure on the top of the metal sheet. The four first springs 13 serve as buffers, and the two pressure sensors 17 move downward, causing the two second springs 16 to deform under pressure. The first springs 13 and the second springs 16 are made of the same specifications and materials. Therefore, when the compression force of the second spring 16 is detected, the magnitude of the compression force of the first spring 13 can be detected to achieve the purpose of detecting the extrusion force between the drawing roller 18 and the metal sheet, preventing the extrusion force between the drawing roller 18 and the metal sheet from being too large, and meeting the drawing requirements of different metal sheets.
[0030] It should be noted that, in actual use, an existing technology controller can be added. The controller is electrically connected to multiple electric rollers 2, water pumps, electric push rods 10, and pressure sensors 17 to facilitate overall control. The specific data analysis and processing involved to further realize the control function are methods that can be implemented by those skilled in the art based on common knowledge. These methods are not within the scope of this solution. The above description is merely to illustrate the beneficial effects that can be achieved by this hardware structure improvement in conjunction with common knowledge.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
