Description

Technical Field

[0001] The present invention relates to the technical field of screw processing, and specifically provides a multi-station screw processing production line. Background Art

[0002] A screw refers to a bolt, which is a tool for gradually fastening machine parts by using the physical and mathematical principles of the inclined plane circular rotation and friction of an object. When processing screws, a screw processing production line is required to process the screws.

[0003] The current screw processing production line, for example, a screw processing production line and production process proposed in the publication number: CN114406154B, includes a frame. The frame is provided with an unwinding assembly and a cutting assembly. A fixing table is arranged between the unwinding assembly and the cutting assembly. The fixing table is provided with a plurality of straightening assemblies. Each straightening assembly includes a support frame, a first hydraulic cylinder, a pressing block, two connecting rods, and two clamping blocks. The support frame is fixedly connected to the fixing table. The first hydraulic cylinder is fixedly connected to the support frame. The pressing block is fixedly connected to the output end of the first hydraulic cylinder. The two connecting rods are respectively hinged on both sides of the pressing block. One end of the connecting rod away from the pressing block is hinged to the clamping block. The fixing table is provided with a limiting groove that matches the clamping block. The lower end of the clamping block is located in the limiting groove, and the clamping blocks are all slidably connected to the limiting groove. In this application, the output end of the first hydraulic cylinder drives the pressing block to reciprocate up and down. The pressing block and the clamping block flatten the metal strip in the vertical and horizontal directions, making the metal strip relatively straight, which is beneficial to ensuring the forming effect of subsequent screws.

[0004] When the existing screw processing production line is in use, although it is beneficial to ensure the forming effect of subsequent screws, it is found in use that the screws are processed by a production line with a single station, and after the material roll finishes feeding, the material roll needs to be replaced. During the process of replacing the material roll, the equipment stops working for a long time, resulting in a relatively low overall working efficiency of screw processing and inconvenience in use. Therefore, we propose a multi-station screw processing production line to solve the problems raised. Summary of the Invention

[0005] The purpose of the present invention is to provide a multi-station screw processing production line to solve the problems in the current market proposed in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A multi-station screw processing production line includes a base. A turntable is rotatably connected to the top of the base. The turntable is driven by a driving mechanism to rotate. Among them, On the same side of the turntable, workbenches are symmetrically arranged. On both sides of the workbench near the other workbench, first brackets are evenly and fixedly connected to the top at equal intervals. A straightening roller is rotatably connected between the first brackets. Above the workbench far from the other workbench, a traction mechanism is provided. At the top of one end of the workbench far from the other workbench, a U-shaped frame is fixedly connected. A hydraulic rod is installed in the middle of the U-shaped frame, and a cutting knife is installed at the bottom end of the hydraulic rod. On the top of the workbench corresponding to the inner side of the U-shaped frame, a shearing table is installed. On both sides of the top of the turntable, roller racks are symmetrically and fixedly connected. On the outer side of the roller rack near the upper part, a movable frame is rotatably connected. A roller is placed on the roller rack. At both ends of the roller, rotating shafts are symmetrically and fixedly connected. On one side of the roller rack and the movable frame corresponding to the rotating shaft, a rotating shaft groove is opened. When the turntable rotates, the movable frame is driven to automatically open or close through a transmission mechanism.

[0007] Preferably, the driving mechanism includes a first reversing gear. The bottom of the shaft end of the turntable is fixedly connected with a first reversing gear. A first motor is installed at the bottom of the base corresponding to the first reversing gear. A second reversing gear is fixedly connected to the shaft end of the first motor corresponding to the first reversing gear.

[0008] Preferably, the first reversing gear and the second reversing gear are perpendicular to each other and meshed with each other.

[0009] Preferably, the traction mechanism includes a second bracket. Second brackets are symmetrically and fixedly connected above the workbench far from the turntable. A second motor is installed on the outer side of the second bracket. Traction rollers are rotatably connected symmetrically above and below between the second brackets. Transmission gears are fixedly connected to the same ends of the traction rollers far from the second motor.

[0010] Preferably, the transmission gears are meshed with each other.

[0011] Preferably, the inner wall of the rotating shaft groove is provided with ball grooves at equal intervals, and balls are arranged inside the ball grooves.

[0012] Preferably, the transmission mechanism includes a chute. A chute is opened at the top of the turntable corresponding to the outer side of the roller rack. A slider is arranged in the chute. A transmission rod is rotatably connected between the top of the slider and the movable frame. A slide rod groove is communicated with the bottom of the turntable corresponding to the chute. A slide rod is fixedly connected to the bottom of the slider corresponding to the slide rod groove. A first transmission groove is opened on the circumferential side of the top of the base near the outer side, and a second transmission groove is opened on the circumferential side of the top of the base near the inner side.

[0013] Preferably, both the slider and the chute are T-shaped, and the external dimension of the slider matches the internal dimension of the chute.

[0014] Preferably, the inner diameter of the first transmission groove and the second transmission groove near the workbench is smaller than that on the side away from the workbench, and the inner width of the first transmission groove and the second transmission groove matches the outer diameter of the slide rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, there are a total of four sets of material roller racks and movable frames. When two of them rotate to the workbench, the movable frames are in a closed state, and the material roller is limited by the material roller rack and the movable frame. While the two movable frames away from the workbench are in an open state, the turntable is driven by the driving mechanism to rotate, enabling the conversion of the four sets of material roller racks and movable frames. When two of them are working, the material rollers of the other two can be replaced. Cooperating with the two workbenches to straighten and shear the metal wire simultaneously can effectively improve the production efficiency of screw processing.

[0016] In the present invention, the slide rods on both sides of a single set of material roller racks are respectively located in the first transmission groove and the second transmission groove. When the turntable is driven by the driving mechanism to rotate, the positions of the four sets of material roller racks can be converted. While rotating, the first transmission groove and the second transmission groove cooperate with the slide rods to drive the sliders on both sides of the material roller rack to approach or move away from each other. When the slider moves, the movable frame can be driven to unfold or close with the material roller rack through the transmission rod. When the material roller rack moves away from the workbench, the first transmission groove and the second transmission groove cooperate with the slide rods to drive the movable frame to open, and when moving towards the workbench, it can drive the movable frame to close. Through the provided transmission mechanism, the turntable can drive the movable frame to automatically open or close while rotating, so as to replace the material roller.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention. Embodiment

[0020] Please refer to Figures 1 to 6 , the present invention provides a technical solution: a multi-station screw processing production line, including a base 1, the top of the base 1 is rotatably connected with a turntable 2, and the turntable 2 is driven by a driving mechanism to rotate. Among them, Workbenches 6 are symmetrically arranged on the same side of the turntable 2. On both sides of the workbench 6 close to the workbench 6, first supports 7 are evenly and fixedly connected at equal intervals. A straightening roller 8 is rotatably connected between the first supports 7. A traction mechanism is arranged above the workbench 6 far from the workbench 6. At the top of one end of the workbench 6 far from the workbench 6, a U-shaped frame 13 is fixedly connected. A hydraulic rod 14 is installed in the middle of the U-shaped frame 13, and a cutter 15 is installed at the bottom end of the hydraulic rod 14; A shearing table 16 is installed on the top of the workbench 6 corresponding to the inner side of the U-shaped frame 13. On both sides of the top of the turntable 2, material roller racks 17 are symmetrically and fixedly connected. On the outer side of the material roller racks 17 close to the upper part, a movable frame 18 is rotatably connected. Material rollers 19 are arranged on the material roller racks 17. Rotating shafts 20 are symmetrically and fixedly connected to both ends of the material roller 19. Shaft grooves 21 are opened on one side of the material roller racks 17 and the movable frame 18 corresponding to the rotating shafts 20. When the turntable 2 rotates, the movable frame 18 is driven by a transmission mechanism to automatically open or close; There are four groups of material roller racks 17 and movable racks 18 in total. When two of them rotate to the workbench 6, the movable racks 18 are in a closed state, and the material roller 19 is limited by the material roller rack 17 and the movable rack 18. While the two movable racks 18 far away from the workbench 6 are in an open state. By driving the turntable 2 through the drive mechanism, the four groups of material roller racks 17 and movable racks 18 can be converted, so that when two of them are working, the material rollers 19 of the other two groups can be replaced. Cooperating with the two workbenches 6 to straighten and shear the metal wire simultaneously can effectively improve the production efficiency of screw processing.

[0021] Please refer to Figures 1 to 6 , the drive mechanism includes a first reversing gear 3. The bottom of the shaft end of the turntable 2 is fixedly connected with a first reversing gear 3. A first motor 4 is installed at the bottom of the base 1 corresponding to the first reversing gear 3. The shaft end of the first motor 4 corresponding to the first reversing gear 3 is fixedly connected with a second reversing gear 5. The first reversing gear 3 and the second reversing gear 5 are perpendicular to each other, and the first reversing gear 3 meshes with the second reversing gear 5. When the first motor 4 works, it drives the second reversing gear 5 to rotate. The second reversing gear 5 drives the first reversing gear 3 to rotate through meshing, so that the first reversing gear 3 drives the turntable 2. Through the set drive mechanism, the turntable 2 can be driven to rotate by the first motor 4.

[0022] Please refer to Figures 1 to 6 , the traction mechanism includes a second bracket 9. The second brackets 9 are symmetrically and fixedly connected above the workbench 6 far away from the turntable 2. A second motor 10 is installed on the outside of the second brackets 9. The traction rollers 11 are symmetrically and rotatably connected up and down between the second brackets 9. Transmission gears 12 are fixedly connected to the same ends of the traction rollers 11 far away from the second motor 10. The transmission gears 12 mesh with each other. When the second motor 10 works, it drives one of the traction rollers 11 to rotate. The traction rollers 11 rotate in opposite directions through the transmission gears 12, and then the metal wire can be tractioned.

[0023] Please refer to Figures 1 to 6 , the inner wall of the rotating shaft groove 21 is equidistantly provided with ball grooves 22. The balls 23 are arranged inside the ball grooves 22. After the material roller 19 is erected in the rotating shaft groove 21 through the rotating shaft 20, the rotating shaft 20 contacts the inner wall of the rotating shaft groove 21 through the balls 23. When the material roller 19 rotates during material feeding, the rolling friction between the balls 23 and the rotating shaft 20 replaces the sliding friction between the rotating shaft 20 and the inner wall of the rotating shaft groove 21, which can effectively reduce the resistance received by the material roller 19 during material feeding, so that the material roller 19 can feed materials by rotating.

[0024] Please refer to Figures 1 to 6, The transmission mechanism includes a chute 24. A chute 24 is provided at the top of the turntable 2 corresponding to the outside of the material roller rack 17. A slider 25 is arranged in the chute 24. A transmission rod 26 is rotatably connected between the top of the slider 25 and the movable frame 18. A slide rod groove 27 is communicated with the bottom of the turntable 2 corresponding to the chute 24. A slide rod 28 is fixedly connected to the bottom of the slider 25 corresponding to the slide rod groove 27. A first transmission groove 29 is provided on the circumferential side of the top of the base 1 near the outside, and a second transmission groove 30 is provided on the circumferential side of the top of the base 1 near the inside. Both the slider 25 and the chute 24 are T-shaped, and the external dimensions of the slider 25 match the internal dimensions of the chute 24. The inner diameter of the first transmission groove 29 and the second transmission groove 30 near the workbench 6 is smaller than that on the side away from the workbench 6, and the inner width of the first transmission groove 29 and the second transmission groove 30 matches the outer diameter of the slide rod 28. The slide rods 28 on both sides of a single group of material roller racks 17 are respectively located in the first transmission groove 29 and the second transmission groove 30. When the turntable 2 is driven to rotate by the driving mechanism, the positions of the four groups of material roller racks 17 can be converted. During rotation, the first transmission groove 29 and the second transmission groove 30 cooperate with the slide rod 28 to drive the sliders 25 on both sides of the material roller rack 17 to approach or move away from each other. When the slider 25 moves, the transmission rod 26 can drive the movable frame 18 to unfold or close with the material roller rack 17. When the material roller rack 17 moves away from the workbench 6, the first transmission groove 29 and the second transmission groove 30 cooperate with the slide rod 28 to drive the movable frame 18 to open, and when moving towards the workbench 6, it can drive the movable frame 18 to close. Through the provided transmission mechanism, the turntable 2 can drive the movable frame 18 to automatically open or close while rotating, so as to replace the material roller 19.

[0025] Working principle: In this multi-station screw processing production line, there are four groups of material roller racks 17 and movable frames 18. When two of them rotate to the workbench 6, the movable frames 18 are in a closed state, and the material roller 19 is limited by the material roller rack 17 and the movable frame 18. The two movable frames 18 away from the workbench 6 are in an open state. By driving the turntable 2 to rotate through the driving mechanism, the four groups of material roller racks 17 and movable frames 18 can be converted, so that when two of them are working, the material rollers 19 of the other two groups can be replaced. Cooperating with the two workbenches 6 to straighten and shear the metal wire simultaneously can effectively improve the production efficiency of screw processing. When the first motor 4 works, it drives the second reversing gear 5 to rotate. The second reversing gear 5 drives the first reversing gear 3 to rotate through meshing, so that the first reversing gear 3 drives the turntable 2. Through the provided driving mechanism, the turntable 2 can be driven to rotate by the first motor 4. And when the second motor 10 works, it drives one of the traction rollers 11 to rotate. The traction rollers 11 rotate in opposite directions through the transmission gears 12, and thus the metal wire can be tractioned; The slide bars 28 on both sides of the single-group material roller rack 17 are respectively located in the first drive groove 29 and the second drive groove 30. When the turntable 2 is driven by the drive mechanism to rotate, the positions of the four groups of material roller racks 17 can be converted. While rotating, the first drive groove 29 and the second drive groove 30 cooperate with the slide bar 28 to enable the sliders 25 on both sides of the material roller rack 17 to approach or move away from each other. When the slider 25 moves, the movable frame 18 can be driven to unfold or close with the material roller rack 17 through the transmission rod 26. When the material roller rack 17 moves away from the workbench 6, the first drive groove 29 and the second drive groove 30 cooperate with the slide bar 28 to drive the movable frame 18 to open, and when moving towards the workbench 6, it can drive the movable frame 18 to close. Through the arranged transmission mechanism, the turntable 2 can drive the movable frame 18 to automatically open or close while rotating, so as to replace the material roller 19.
