Description

Technical Field

[0001] This application relates to the field of steel coil production, and in particular to a steel coil punching production line mechanism. Background Technology

[0002] Steel coils, also known as rolled steel, are steel products that have been hot-pressed or cold-pressed into coils. They are used for storage and transportation, and for various processing (such as processing into steel plates, steel strips, etc.).

[0003] Generally, during the processing of steel coils, a cutting machine (such as a laser cutting machine) is used to cut the steel coils to obtain the required shape.

[0004] However, after the steel coil is cut, cutting waste is easily generated, and this waste is not easy to remove directly from the coil. In this case, manual shaking or pulling is usually used to separate the cutting waste from the coil, which greatly increases the workload and reduces the efficiency of steel coil production. Summary of the Invention

[0005] To improve the low efficiency of steel coil production, this application provides a steel coil punching production line mechanism.

[0006] This application provides a steel coil punching production line mechanism, which adopts the following technical solution: A steel coil punching production line mechanism includes: a worktable and an unwinding roller and a winding roller disposed on the worktable. A drive motor is installed on the worktable and connected to the winding roller. A scrap roller is rotatably mounted on the worktable. A starter motor is installed on the worktable, and the output shaft of the starter motor is coaxially fixed with the scrap roller. A separation plate is fixedly disposed on the worktable. The scrap roller is located above the separation plate and on the side of the separation plate closer to the unwinding roller. A punching assembly is disposed on the worktable.

[0007] By adopting the above technical solution, after the steel coil is placed on the unwinding roller, one end of the steel coil is passed between the separating plate and the worktable, and the cutting waste at that end is pre-separated from the steel coil; then the steel coil is fixed to the winding roller, and the cutting waste is fixed to the waste roller; then the drive motor and starter motor are started to drive the winding roller and waste roller to rotate, and under the action of the separating plate, the steel coil and cutting waste are separated and wound onto the winding roller and waste roller, so as to achieve the effect of quickly separating the cutting waste from the steel coil, thereby improving the production efficiency of steel coil.

[0008] Optionally, the punching assembly includes: a support plate, a punching table, a punching blade, and a punching cylinder. The punching table is fixed on the worktable, the support plate is fixed on the worktable, the punching cylinder is fixed on the support plate, and the push shaft of the punching cylinder is fixed to the punching blade.

[0009] By adopting the above technical solution, after the length of the steel coil wound on the take-up roller reaches the required length, the punching cylinder is activated to push the punching blade downward until it contacts the steel coil and presses the steel coil onto the punching table to punch the steel coil, thereby achieving the effect of segmenting the steel coil.

[0010] Optionally, a pair of flattening rollers are rotatably mounted on the worktable.

[0011] By adopting the above technical solution, before the steel coil passes between the separating plate and the worktable, the steel coil is first passed between two flattening rollers, thereby flattening the steel coil.

[0012] Optionally, a clamping assembly is provided between the punching table and the punching cylinder, multiple take-up rollers are provided, a bearing assembly is provided between the take-up rollers and the worktable, and a continuing assembly is provided on the take-up rollers.

[0013] By adopting the above technical solution, after the steel coil is punched, the next take-up roller is adjusted to be close to the punching table using the bearing component. Then, the clamping component can automatically clamp the cut end of the steel coil to the next take-up roller, and the continuing component on the next take-up roller can automatically fix the steel coil, so that the steel coil can continue to be wound up, which greatly improves the efficiency of steel coil winding.

[0014] Optionally, the bearing assembly includes: a rotating disk and a stepper motor, the stepper motor is mounted on the worktable, and the output shaft of the stepper motor is coaxially fixed with the rotating disk, the take-up roller is rotatably mounted on the rotating disk, and the drive motor is mounted on the rotating disk.

[0015] By adopting the above technical solution, after the steel coil is punched, the stepper motor is started to drive the rotating disk to rotate, thereby rotating the next winding roller to be close to the punching table; then the cut end of the steel coil is fixed on the next winding roller, so that the steel coil can continue to be wound up.

[0016] Optionally, the clamping assembly includes a clamping part and a pulling part. The clamping part includes a slider, a tension spring, a clamping frame, a clamping plate, and a clamping spring. A groove is provided on the punching table. The slider is slidably connected in the groove, and the tension spring is fixed between the slider and the inner wall of the groove. The clamping frame is fixed on the slider. The clamping plate is slidably disposed in the clamping frame. The clamping spring is fixed between the clamping plate and the clamping frame. The pulling part is disposed between the slider and the punching blade.

[0017] By adopting the above technical solution, during the coiling process, the steel coil passes between the clamping plate and the clamping frame, and the clamping spring pushes the clamping plate downward to clamp the steel coil, thereby facilitating the clamping of the steel coil.

[0018] Optionally, the pulling part includes: a pulling rope, a first magnetic block, a connecting rod, and a second magnetic block. One end of the pulling rope is fixed to the slider, and the other end extends outward through the punching table and is fixed to the first magnetic block. The connecting rod is fixed to the punching blade, and a receiving hole is provided on the connecting rod. The second magnetic block is fixed in the receiving hole.

[0019] By adopting the above technical solution, when the punch cutter cuts the steel coil downwards, the punch cutter drives the connecting rod to descend together. After the punch cutter contacts the steel coil, the first magnetic block is inserted into the receiving hole and is magnetically attracted to the second magnetic block. After the punch cutter finishes cutting the steel coil, the punch cutter drives the connecting rod to move upwards. Since the first magnetic block is attracted to the second magnetic block, the first magnetic block will pull the pulling rope, which will pull the slider closer to the winding roller until the connecting assembly can connect the steel coil.

[0020] Optionally, the connecting assembly includes: an extension part, a reaction part, and two sets of clamping parts. The extension part includes: an iron plate, an electromagnetic chuck, and a push spring. The take-up roller has a receiving groove. The electromagnetic chuck is fixed to the bottom of the receiving groove. The iron plate is slidably disposed in the receiving groove, and the push spring is fixed between the electromagnetic chuck and the iron plate. The clamping part is disposed on the iron plate, and the reaction part is disposed on the clamping part.

[0021] By adopting the above technical solution, when the electromagnetic chuck is not adsorbing the iron plate, the push spring pushes the iron plate out of the receiving groove, thereby welcoming the steel coil so that the steel coil can be inserted into the iron plate.

[0022] Optionally, the clamping part includes: a pressure plate, a connecting rope, and a clamping spring. One end of the clamping spring is fixed to the iron plate and the other end is fixed to the pressure plate. One end of the connecting rope is fixed to the electromagnetic chuck and the other end passes through the iron plate and is fixed to the pressure plate. The reaction part is disposed between the two pressure plates.

[0023] By adopting the above technical solution, when the spring pushes the iron plate outward, the connecting rope will pull the pressure plate, thereby increasing the distance between the two pressure plates so that the steel coil can be inserted; when the iron plate is retracted into the receiving groove, the compression spring will restore its deformation to push the two pressure plates closer to each other, thereby pressing the steel coil.

[0024] Optionally, the reaction unit includes an infrared emitter and an infrared receiver, with a first hole on one of the pressure plates and a second hole on the other pressure plate, the infrared emitter being disposed in the first hole and the infrared receiver being disposed in the second hole.

[0025] By adopting the above technical solution, after the steel coil is inserted into the two pressure plates, the steel coil will block the infrared transmitter so that the infrared receiver cannot receive the signal, thereby controlling the electromagnetic chuck to start and adsorb the iron plate, so that the iron plate will be retracted into the receiving groove.

[0026] In summary, this application includes at least one of the following beneficial effects: 1. Start the drive motor and starter motor to drive the take-up roller and scrap roller to rotate. Under the action of the separation plate, the steel coil and cutting waste are separated and wound onto the take-up roller and scrap roller, so as to achieve the effect of quickly separating the cutting waste from the steel coil, thereby improving the production efficiency of steel coil.

[0027] 2. After the length of the steel coil wound on the take-up roller reaches the required length, start the punching cylinder to push the punching blade downward until it contacts the steel coil and presses the steel coil onto the punching table to punch the steel coil, thereby achieving the effect of segmenting the steel coil.

[0028] 3. When the spring pushes the iron plate outward, the connecting rope will pull the pressure plate, thereby increasing the distance between the two pressure plates so that the steel coil can be inserted; when the iron plate is retracted into the receiving groove, the compression spring will restore its deformation to push the two pressure plates closer to each other, thereby pressing the steel coil.

[0031] This application provides a steel coil punching production line mechanism.

[0032] See Figure 1 A steel coil punching production line mechanism generally includes: a worktable 1 and an unwinding roller 11 and a winding roller 12 rotatably mounted on the worktable 1. In this embodiment, three winding rollers 12 are provided and mounted on the worktable 1 via a support assembly 3. The unwinding roller 11 and the winding roller 12 are located at both ends of the worktable 1 along its length. A drive motor 122 is mounted on the support assembly 3, and the output shaft of the drive motor 122 is coaxially fixed with the winding roller 12. During processing, the cut and coiled steel coil is placed on the unwinding roller 11, and then one end of the steel coil is fixed on any one of the winding rollers 12. The corresponding drive motor 122 is started to drive the winding roller 12 to rotate, thereby winding the steel coil on the unwinding roller 11 onto the winding roller 12.

[0033] See Figure 1A separation plate 14 is fixedly installed on the top wall of the workbench 1, with a gap between the separation plate 14 and the top wall of the workbench 1. A scrap roller 13 is rotatably mounted on the workbench 1, located between the separation plate 14 and the unwinding roller 11, and the height of the scrap roller 13 is higher than the height of the separation plate 14 and the unwinding roller 11. A starter motor 131 is fixedly installed on the top of the workbench 1, and the output shaft of the starter motor 131 is coaxially fixed with the scrap roller 13. After the steel coil is sleeved on the unwinding roller 11, one end of the steel coil is passed through the gap between the separation plate 14 and the workbench 1, and the cutting scrap at that end is pre-separated from the steel coil; then the steel coil is fixed to any one of the take-up rollers 12, and the cutting scrap is fixed to the scrap roller 13. Then, drive motor 122 and starter motor 131 are started to drive take-up roller 12 and scrap roller 13 to rotate. Under the action of separation plate 14, the steel coil and cutting waste are separated and wound onto take-up roller 12 and scrap roller 13 to achieve the effect of quickly separating cutting waste from steel coil, thereby improving the production efficiency of steel coil.

[0034] See Figure 1 Furthermore, a pair of flattening rollers 15 are rotatably mounted on the worktable 1. The flattening rollers 15 are located between the unwinding roller 11 and the separating plate 14, and the two flattening rollers 15 are arranged vertically. Before the steel coil is passed through the space between the separating plate 14 and the worktable 1, the steel coil is first passed through the space between the two flattening rollers 15, thereby flattening the steel coil.

[0035] See Figure 1 The workbench 1 is equipped with a punching assembly 2, which is located between the take-up roller 12 and the separating plate 14. The punching assembly 2 can punch the steel coil that has been separated from the cutting waste to achieve the effect of segmentation, thereby obtaining the required length of steel coil.

[0036] See Figure 1 The punching assembly 2 includes: a support plate 21, a punching table 22, a punching blade 23, and a punching cylinder 24. The punching table 22 is fixed on the workbench 1, the support plate 21 is fixed on the workbench 1, and the punching cylinder 24 is mounted on the support plate 21. The punching cylinder 24 is vertically arranged and located above the punching table 22.

[0037] See Figure 1 The push shaft of the punching cylinder 24 is fixed to the punching knife 23. After the length of the steel coil wound on the winding roller 12 reaches the required length, the punching cylinder 24 is activated to push the punching knife 23 downward until it contacts the steel coil and presses the steel coil onto the punching table 22 to punch the steel coil, thereby achieving the effect of segmenting the steel coil.

[0038] See Figure 1The supporting component 3 includes a rotating disk 31 and a stepper motor 32. The stepper motor 32 is fixed on the worktable 1, and the output shaft of the stepper motor 32 is coaxially fixed with the rotating disk 31. The three take-up rollers 12 are evenly distributed at 120° along the circumference of the rotating disk 31. After the steel coil is punched, the stepper motor 32 is started to drive the rotating disk 31 to rotate, thereby rotating the next take-up roller 12 to be close to the punching table 22. Then the cut end of the steel coil (connected to the unwinding roller 11) is fixed on the next take-up roller 12, so that the steel coil can continue to be wound up.

[0039] See Figure 2 and Figure 3 A clamping assembly is provided between the punching table 22 and the punching cylinder 24, and a continuing assembly is provided on the winding roller 12. After the steel coil is punched, the clamping assembly can automatically clamp the cut end of the steel coil to the next winding roller 12, and the continuing assembly on the next winding roller 12 can automatically fix the steel coil, thereby continuing to wind the steel coil, which greatly improves the efficiency of winding the steel coil.

[0040] See Figure 4 and Figure 5 The clamping assembly includes a clamping part 4 and a pulling part 5.

[0041] See Figure 1 and Figure 4 The clamping part 4 includes: a slider 41, a tension spring 42, a clamping frame 43, a clamping plate 44, and a clamping spring 45. The punching table 22 has grooves 221 at both ends along the width direction and along the length direction. The slider 41 is slidably connected to the grooves 221 and slides along the length direction of the grooves 221. The clamping frame 43 is fixed to the top wall of the slider 41, and the clamping plate 44 is slidably connected to the clamping frame 43 and slides in the vertical direction.

[0042] See Figure 4 One end of the clamping spring 45 is fixed to the top wall of the clamping plate 44, and the other end is fixed to the inner top wall of the clamping frame 43. During the winding process, the steel coil passes between the clamping plate 44 and the clamping frame 43, and the clamping spring 45 pushes the clamping plate 44 to move downward to clamp the steel coil, thereby facilitating the clamping of the steel coil.

[0043] See Figure 4 Furthermore, the clamping part 4 also includes a rubber pad, which is fixed to the bottom of the clamping plate 44. The rubber pad can increase the friction between the clamping plate 44 and the steel coil, thereby improving the stability of the steel coil clamping.

[0044] See Figure 5, the pulling part 5 comprises a pulling rope 51, a first magnetic block 52, a connecting rod 53 and a second magnetic block 54, one end of the pulling rope 51 is fixed to a side of the sliding block 41 away from the separating plate 14, the other end penetrates through one end of the punching table 22 away from the separating plate 14 and is fixed to the first magnetic block 52, and the first magnetic block 52 abuts against the top wall of the punching table 22. One end of the connecting rod 53 is fixed to the punching table 22 and arranged horizontally, a bottom wall of the other end is provided with an accommodation hole 531, and the second magnetic block 54 is fixed to the hole bottom of the accommodation hole 531.

[0045] Referring to Figure 1 , one end of the tension spring 42 is fixed to a side of the sliding block 41 away from the pulling rope 51, and the other end is fixed to the inner side wall of the sliding groove 221. In the embodiment of the present application, the magnetic attraction force between the first magnetic block 52 and the second magnetic block 54 is greater than the pulling force of the tension spring 42. When the punching knife 23 punches the steel coil downward, the punching knife 23 drives the connecting rod 53 to descend together, and after the punching knife 23 contacts the steel coil, the first magnetic block 52 is inserted into the accommodation hole 531 and magnetically attracted to the second magnetic block 54; after the punching knife 23 completes cutting the steel coil, the punching knife 23 drives the connecting rod 53 to move upward, and due to the attraction between the first magnetic block 52 and the second magnetic block 54, the first magnetic block 52 pulls the pulling rope 51, and the pulling rope 51 pulls the sliding block 41 to approach the winding roller 12 until the connecting assembly can connect the steel coil; then the punching knife 23 continues to move upward, at this time the sliding block 41 cannot slide further, so that the first magnetic block 52 will fall off from the accommodation hole 531; and the tension spring 42 restores its deformation to reset the sliding block 41, so that after the subsequent steel coil is punched again, the steel coil can be clamped continuously.

[0046] Referring to Figure 6 , the connecting assembly comprises: an extending part 6, a reaction part 8 and two sets of pressing parts 7.

[0047] Referring to Figure 6 , the extending part 6 comprises an iron plate 61, an electromagnetic chuck 62 and a pushing spring 63, a side wall of the winding roller 12 along the length direction is provided with an accommodation groove 121, one end of the accommodation groove 121 away from the driving motor 122 penetrates through the winding roller 12; the electromagnetic chuck 62 is fixed to the groove bottom of the accommodation groove 121. The iron plate 61 is slidably connected in the accommodation groove 121 and slides along the depth direction of the accommodation groove 121, and in the embodiment of the present application, the iron plate 61 is in a "匚"-shape (C-channel shape).

[0048] Referring to Figure 6 , one end of the pushing spring 63 is fixed to the electromagnetic chuck 62, the other end is fixed to the side wall of the iron plate 61, and the pushing spring 63 is configured to push the iron plate 61 to move out of the accommodation groove 121.

[0049] Referring to Figure 6The pressing part 7 includes a pressure plate 71, a connecting rope 72, and a pressing spring 73. One end of any pressing spring 73 is fixed to the inner top wall of the iron plate 61, and the other end is fixed to the corresponding pressure plate 71. One end of another pressing spring 73 is fixed to the inner bottom wall of the iron plate 61, and the other end is fixed to the corresponding pressure plate 71. The steel coil can be inserted between the two pressure plates 71 to press the steel coil.

[0050] See Figure 6 One end of the connecting rope 72 is fixed to the electromagnetic chuck 62, and the other end passes through the iron plate 61 and is fixed to the side of the pressure plate 71 near the compression spring 73. When the spring 63 pushes the iron plate 61 outward, the connecting rope 72 will pull the pressure plate 71, thereby increasing the distance between the two pressure plates 71 so that the steel coil can be inserted. When the iron plate 61 is retracted into the receiving groove 121, the compression spring 73 will restore its deformation to push the two pressure plates 71 closer to each other, thereby pressing the steel coil.

[0051] See Figure 6 The reaction unit 8 includes an infrared transmitter 81 and an infrared receiver 82. A first hole 711 is formed on the side of one pressure plate 71 facing away from the compression spring 73; a second hole 712 is formed on the side of the other pressure plate 71 facing away from the compression spring 73. The infrared transmitter 81 is fixed in the first hole 711, and the infrared receiver 82 is fixed in the second hole 712. In this embodiment, the infrared transmitter 81, the infrared receiver 82, and all electrical equipment are connected to the controller for control.

[0052] As the cut end of the steel coil is being carried away from the separating plate 14, the steel coil will be inserted between the two pressure plates 71. After the steel coil is inserted, it will cover the infrared transmitter 81 so that the infrared receiver 82 cannot receive the signal. As a result, the controller will activate the electromagnetic chuck 62 to attract the iron plate 61, so that the iron plate 61 will be retracted into the receiving groove 121. During the recycling process, the two pressure plates 71 move closer and closer until they press the steel coil tightly. Finally, the corresponding drive motor 122 is started to drive the winding roller 12 to rotate, thereby winding the steel coil.

[0053] The working principle of the steel coil punching production line mechanism of this application is as follows: After the steel coil is sleeved on the unwinding roller 11, one end of the steel coil is passed between the separation plate 14 and the worktable 1, and the cutting waste at that end is separated from the steel coil in advance; then the steel coil is fixed to any one of the winding rollers 12, and the cutting waste is fixed to the waste roller 13. Then, drive motor 122 and starter motor 131 are started to drive take-up roller 12 and scrap roller 13 to rotate. Under the action of separation plate 14, the steel coil and cutting waste are separated and wound onto take-up roller 12 and scrap roller 13 to achieve the effect of quickly separating cutting waste from steel coil, thereby improving the production efficiency of steel coil.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
