Description

Technical Field

[0001] The invention relates to the field of mechanical metal expansion nets, in particular to a metal expansion net processing device. Background Art

[0002] The expanded metal mesh process is a method of forming a continuous mesh pattern by cutting and stretching metal sheets. Unlike woven or welded mesh, expanded metal mesh is made from a single piece of metal material, so there are no joints or welds, and it has higher strength and durability. The expanded metal process can produce high-strength, lightweight and durable metal mesh, which can be used in wind power, aviation, lightning protection, electromagnetic shielding, construction (such as fencing, security), industry (such as ventilation grilles, filters) and decorative purposes (such as architectural decoration).

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] It should be noted that the present invention is provided with a controller and a corresponding operation panel, and the metal plate is placed on the top of the supporting mesh plate 8, and its end is placed between the two conveying rollers 10. When working, the driving unit drives the lifting plate 3 to lift and lower back and forth. When the lifting plate 3 moves downward, under the action of the linkage unit, the driving shaft 13 is in a stationary state, and the lifting plate 3 drives the punch 7 to cut the metal plate through the upper mold 6, so as to cut the metal plate into a series of straight line cuts or special-shaped holes, and the waste cut by the stamping falls into the collecting tank 9 through the through hole of the supporting mesh plate 8. When the lifting plate 3 moves upward, it drives the driving shaft 13 to rotate, and the driving shaft 13 drives the shaftless spiral blade 11 to rotate, and the shaftless spiral blade 11 cuts the waste inside the collecting tank 9. It is discharged from one end. When the driving shaft 13 rotates, the driving shaft 13 drives the conveying roller 10 to rotate through the transmission belt assembly 20. The conveying roller 10 conveys the metal plate forward, and the burrs generated by the cutting can be flattened by the extrusion of the conveying roller 10. An infrared sensor is provided on the top of the stretching frame 24. When the cut metal plate enters the moving frame 1 25, the pressing plate 1 27 fixes the end of the metal plate, and the pressing plate 2 31 fixes the other end of the metal plate downward, and the metal plate is cut off by the cutting knife 32. The moving frame 1 25 moves to one end to stretch the metal plate. When the plate is stretched, the metal gap is stretched into a diamond hole or other patterns, so that the metal plate is cut and stretched into a metal mesh.

[0031] like Figure 1 ,2 As shown in , 3, the driving part includes a crankshaft 22 rotatably installed on the top of the equipment frame 1, the top of the equipment frame 1 is fixedly connected with a motor 23, the motor 23 is transmission-connected to the crankshaft 22 through a transmission belt assembly, the middle part of the crankshaft 22 is rotationally connected with a connecting rod, the bottom of the connecting rod is rotationally connected with a connecting rod 4, the connecting rod 4 is fixedly connected to the lifting plate 3, the inner side of the equipment frame 1 is fixedly connected with a limit baffle 2, the limit baffle 2 is slidably connected to the lifting plate 3, the top of the limit baffle 2 is fixedly connected with a lifting slide bar 5, the lifting plate 3 is slidably connected to the lifting slide bar 5.

[0032] It should be noted that the motor 23 of the present invention drives the large pulley to rotate through the small pulley and the transmission belt, and the large pulley drives the crankshaft 22 to rotate. The connecting rod 4 is connected to the middle part of the crankshaft 22 by rotation, and transmits the rotational movement of the crankshaft to the lifting part. The bottom of the connecting rod 4 is fixedly connected to the lifting plate 3, and the lifting movement of the lifting plate 3 is driven thereby. The function of the limit baffle 2 is to limit the range of motion of the lifting plate to prevent the lifting plate 3 from exceeding the predetermined up and down stroke. The limit baffle 2 and the lifting plate 3 are slidably connected, and the limit guide ensures that the lifting plate 3 can move stably during lifting. The top of the limit baffle 2 is fixedly connected with a lifting slide bar 5, and the lifting plate 3 is slidably connected to the equipment frame through the lifting slide bar to ensure that the lifting plate 3 can move up and down smoothly. The motor 23 drives the crankshaft 22 to rotate, and the crankshaft 22 drives the movement of the connecting rod, and then drives the lifting plate 3 to move up and down through the connecting rod 4. The sliding connection between the limit baffle 2 and the lifting plate 3 and the lifting slide bar 5 ensure that the lifting plate 3 can be lifted and lowered smoothly within the specified range.

[0033] like Figure 2 , 3 As shown, the bottom of the lifting plate 3 is fixedly connected to the upper mold 6, the punch 7 is fixedly connected to the bottom of the upper mold 6, the outer side of the punch 7 is slidably connected to the pressure plate, and a return spring is installed between the pressure plate and the upper mold 6.

[0034] It should be noted that, in the present invention, when the lifting plate 3 drives the upper mold 6 to move downward, under the action of the reset spring, the pressure plate first contacts the metal plate, and the metal plate is pressed and fixed by the elastic force of the reset spring. When the punch 7 penetrates the pressure plate and contacts the metal plate, the metal plate is cut. When the lifting plate 3 drives the upper mold 6 to move upward, the punch 7 is separated from the metal plate, and then the upper mold 6 drives the pressure plate to separate from the metal plate through the reset spring, so as to prevent the punch 7 from lifting the metal plate and prevent the metal plate from being dislocated.

[0035] like Figure 2 , 3As shown, two conveyor rollers 10 are arranged up and down, and are used to convey metal plates, level them, and remove sharp edges of metal plates. A transmission gear 21 is evenly fixed to one end of the conveyor roller 10, and the upper and lower transmission gears 21 are meshed and connected to each other. One side of the conveyor roller 10 located at the bottom is connected to the drive shaft 13 through a transmission belt assembly 20.

[0036] It should be noted that, in the present invention, when the lifting plate 3 moves upward, the lifting plate 3 drives the gear 14 to rotate, and the gear 14 drives the inner ratchet 15 to rotate. Because there is a movement gap between the inner ratchet 15 and the pawl 17, during the transmission cooperation between the pawl 17 and the inner ratchet 15, due to the small thickness of the metal plate, the punch 7 can be quickly separated from the metal plate. When the pawl 17 and the inner ratchet 15 cooperate for transmission, the gear 14 drives the driving disk 16 to rotate through the inner ratchet 15 and the pawl 17, and the driving disk 16 drives the driving shaft 13 to rotate. The driving shaft 13 drives the conveying roller 10 located below to rotate through the belt and the pulley. The conveying roller 10 rotates under the transmission action of the transmission gear 21. During the upward movement of the lifting plate 3, the conveying roller 10 conveys the cut metal plate forward. During the conveying process, under the extrusion action, the conveying roller 10 squeezes the cut metal plate to flatten the cutting burrs.

[0037] like Figure 2 , 3 As shown in , 4 and 5, the linkage part includes a driving rack 12 fixedly connected to the side of the lifting plate 3, the driving rack 12 is slidably connected to the equipment frame 1, the outer side of the driving rack 12 is meshed with a gear 14, the gear 14 is rotatably connected to the driving shaft 13, the inner part of the gear 14 is fixedly connected with an inner ratchet 15, the inner part of the gear 14 is rotatably connected with a driving disk 16, the driving shaft 13 is fixedly connected to the driving disk 16, a receiving groove 19 is provided on the outer side of the driving disk 16, the inner part of the receiving groove 19 is rotatably connected with a pawl 17 for driving the inner ratchet 15, a spring 18 is fixedly connected between the pawl 17 and the inner wall of the receiving groove 19, when the gear 14 rotates clockwise, the pawl 17 is slidably connected to the inner ratchet 15, when the gear 14 rotates counterclockwise, the inner ratchet 15 drives the driving disk 16 to rotate through the pawl 17, and the driving disk 16 drives the shaftless spiral blade 11 through the driving shaft 13 to transport the waste outward.

[0038] It should be noted that the equipment frame 1 of the present invention is provided with a sliding hole that cooperates with the driving rack 12. The lifting plate 3 drives the driving rack 12 to move up and down during the lifting process. When the driving rack 12 moves downward, the driving rack 12 drives the gear 14 to rotate clockwise, and the gear 14 drives the inner ratchet 15 to rotate clockwise. Under the structure of the inclined surface, the inner ratchet 15 squeezes the pawl 17 and is slidably connected with the pawl 17. The pawl 17 squeezes the spring 18 and rotates into the storage groove 19. In this way, the inner ratchet 15 and the driving disk 16 do not transmit, and the driving shaft 13 and the conveying roller 10 are both in a stationary state. When the lifting plate 3 moves upward, the driving rack 12 drives the gear 14 to rotate clockwise. The gear 14 drives the inner ratchet 15 to rotate clockwise. The bar 12 drives the gear 14 to rotate counterclockwise. Under the elastic force of the spring 18, the pawl 17 is stuck in the tooth gap of the inner ratchet 15. The gear 14 cooperates with the pawl 17 through the inner ratchet 15. The inner ratchet 15 drives the driving disk 16 to rotate through the pawl 17. The driving disk 16 drives the driving shaft 13 to rotate. The driving shaft 13 drives the shaftless spiral blade 11 to transport metal, and the driving shaft 13 drives the conveying roller 10 to work through the transmission belt assembly 20. In this cycle, when downward cutting is achieved, the conveying roller 10 and the shaftless spiral blade 11 are stationary. When the cutting is completed, the shaftless spiral blade 11 and the conveying roller 10 rotate to discharge and transport the waste.

[0039] like Figure 6 , 7 As shown in , 8 and 9, the stretching frame 24 is fixedly connected to one side of the equipment frame 1, and the top of the stretching frame 24 is slidably connected to a moving frame 25. The moving frame 25 is a "mouth"-shaped structure, which is used to fix the traction and unloading metal mesh. The top of the moving frame 25 is fixedly connected to a hydraulic cylinder 26. The output end of the hydraulic cylinder 26 is fixedly connected to a pressure plate 27, and the two sides of the transmission gear 21 are fixedly connected to a linear module 28. The moving slide of the linear module 28 is fixedly connected to the moving frame 25. A sliding plate 33 is slidably connected to the side of the top of the stretching frame 24 close to the equipment frame 1. A limiting hole 34 is provided in the middle of the sliding plate 33. The limiting hole 34 is slidably connected to a limiting block inside. The limiting block is fixed to the stretching frame 24, and one end of the limiting block is fixedly connected to a spring 2 36. One end of the spring 2 36 is connected to a pressure sensor 35. The pressure sensor 35 is connected to The limiting hole 34 is fixedly connected, the top of the sliding plate 33 is fixedly connected to the moving frame 29, the top of the moving frame 29 is fixedly connected to the hydraulic cylinder 20, the output end of the hydraulic cylinder 20 is fixedly connected to the pressing plate 21, one side of the pressing plate 21 is fixedly connected to the cutter 32, the top of the sliding plate 33 is provided with a slot hole matching the cutter 32, one side of the sliding plate 33 is fixedly connected to a support plate 37 for supporting the metal mesh and guiding the moving frame 25, the support plate 37 passes through the bottom of the moving frame 25 and is slidably connected to the moving frame 25.

[0040] It should be noted that, in the present invention, under the conveying action of the conveying roller 10, the cut metal plate is a metal mesh structure, the metal mesh passes through the middle of the movable frame 29 and is conveyed forward, and the metal mesh moves toward the movable frame 1 25 at the top of the support plate 37. The bottom of the inner wall of the movable frame 1 25 is an inclined structure, which is convenient for the metal mesh to be inserted into the movable frame 1 25. The support plate 37 is slidably connected to the movable frame 1 25, which is convenient for the movable frame 1 25 to move on the top of the stretching frame 24. The height of the cutter 32 is adjusted by the hydraulic cylinder 2 30, so that the bottom of the cutter 32 is slidably connected to the conveyed metal mesh, so as to scrape the burrs off the metal mesh, and under the limiting action of the cutter 32, a polishing motor can also be installed on one side of the movable frame 29, and the output end of the polishing motor A polishing wheel is fixedly connected, and the metal surface is polished by the polishing wheel. At this time, the movable frame 25 is located in the middle position of the stretching frame 24. When the end of the metal mesh enters the movable frame 25, under the action of the infrared sensor, the controller controls the hydraulic cylinder 26 and the hydraulic cylinder 30 to extend, and the hydraulic cylinder 26 squeezes and fixes the end of the metal mesh inside the movable frame 25 through the pressure plate 27. The hydraulic cylinder 230 drives the pressure plate 231 to squeeze and fix the metal mesh in the movable frame 29, and because the bottom of the cutter 32 is lower than the height of the pressure plate 231, the pressure plate 231 can cut the metal mesh. When the pressure plate 231 squeezes and fixes the cut metal mesh, the linear module 28 drives the movable frame 25 to move to one end, so as to cut the metal mesh. The metal mesh after stretching is stretched, so that the gap is opened into a grid pattern by stretching the plate. In the stretching process, one end of the metal mesh drives the sliding plate 33 to move forward, and the sliding plate 33 drives the pressure sensor 35 to move to one end, so as to leave a certain conveying space for the subsequent conveying of the metal mesh. Because the limit block is fixed to the stretching frame 24 and is slidably connected to the limit hole 34, the limit block squeezes the pressure sensor 35 through the spring 2 36. When the pressure value reaches the specified value, the stretching is stopped, the hydraulic cylinder 1 26 is quickly reset, and the linear module 28 drives the moving frame 1 25 to move toward one end of the moving frame 29. When the moving frame 1 25 is close to the moving frame 29, under the action of the travel switch, the hydraulic cylinder 1 26 drives the pressure plate 1 27 to clamp the stretched mesh, and the hydraulic The pressure cylinder 2 30 controls the pressure plate 2 31 to reset, and the linear module 28 drives the movable frame 25 to move, so that the movable frame 25 pushes the stretched metal mesh to one end. When the movable frame 25 reaches the end of the stretching frame 24, under the action of the travel switch, the hydraulic cylinder 26 drives the pressure plate 27 to reset, and the end of the metal mesh is separated from the movable frame 25 under the action of gravity. When the stretched metal mesh needs to be tested for tensile strength, the hydraulic cylinder 2 30 drives the pressure plate 2 31 to fix one end of the metal mesh, and the hydraulic cylinder 26 drives the pressure plate 27 to clamp and fix the other end of the metal mesh. The movable frame 25 is driven to move to one end through the linear module 28. Under the action of tension, the hydraulic cylinder 26 applies pressure to the pressure sensor 35. During the stretching process,The value of the pressure sensor 35 is gradually increasing. When the metal mesh is disconnected, the value of the pressure sensor 35 will become smaller, and the tensile strength of the metal mesh can be judged by the maximum value.
