Steel wire differential take-up device

Abstract

This utility model discloses a differential speed tightening device for steel wire, including a base. A front-end tightening device is fixed to the left end of the top surface of the base, and a rear-end tightening device is fixed to the right end of the top surface of the base. In this utility model, a front-end tightening device and a rear-end tightening device are respectively set at both ends of the base. When the first motor and the second motor are started, the first motor and the second motor drive the corresponding upper guide roller to rotate. With the auxiliary rotation of the lower guide roller, the steel wire located in the groove on the surface of the combined guide wheel obtains different speeds at the front-end tightening device and the rear-end tightening device. The speed of the first motor is set to be greater than that of the second motor by the motor controller, so that the linear speed of the steel wire before and after a certain production process is different, generating tension. Since the speed of the front end is faster and the speed of the rear end is slower, this speed difference will cause the steel wire to be tightened, achieving the tightening effect and ensuring that the produced steel wire has good performance.

Description

Technical Field

[0001] This utility model relates to the field of steel wire production technology, and in particular to a steel wire differential tightening device. Background Technology

[0002] Currently, steel wire requires multiple processes during production, such as wire drawing, coating, and twisting. During these processes, the steel wire needs to maintain a certain tension to ensure that the produced steel wire has good performance, so a tightening device is required.

[0003] In the prior art, application number CN202322007728.4 discloses a tightening device for steel wire rope production, including a workbench. Two bases are slidably connected inside the workbench, and two mounting plates are fixedly connected to the top of each base. A motor is fixedly connected to the outside of one of the mounting plates. A gear is arranged on the adjacent sides of the two mounting plates, and two limiting rods are fixedly connected to the outside of the gear. Multiple slots are formed inside the gear, and connecting rods are slidably connected inside these slots. In this invention, driven by the motor, both ends of the steel wire rope can be clamped and twisted in opposite directions, thus tightening the steel wire rope. This is more convenient than manual tightening with auxiliary tools, and it can assist in straightening the steel wire rope while tightening, resulting in a better tightening effect and preventing the steel wire rope from becoming tangled.

[0004] However, the above scheme does not include a differential tightening and tension control structure, making it difficult to effectively control the tension of the steel wire, which is detrimental to the production of high-quality and high-performance steel wire.

[0005] To address this issue, a differential wire tightening device is proposed, which has the advantages of easy differential tightening and tension control, thereby solving the problems mentioned in the background technology. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a differential wire tightening device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a differential tensioning device for steel wire, comprising a base, a front tensioning device fixed to the left end of the top surface of the base, and a rear tensioning device fixed to the right end of the top surface of the base, a vertical plate welded to the edge of the top surface of the base, and multiple sets of support wheels rotatably mounted on the surface of the vertical plate, a plurality of tension control devices arranged between the front tensioning device and the rear tensioning device, and a set of support wheels arranged on the left and right sides of each tension control device, a first motor and a second motor respectively mounted on the front tensioning device and the rear tensioning device, and the output ends of the first motor and the second motor are respectively... The upper guide roller is fixed by a coupling. The lower guide roller is installed inside the front and rear tensioning devices corresponding to the upper guide roller. A combined guide wheel is installed on the surface of the lower guide roller and the upper guide roller respectively. The surface of the combined guide wheel is provided with a groove. A rack is inserted through the top of the tension control device, and a tension sensor is fixed at the bottom of the rack. A third motor is fixed on the outer surface of the tension control device, and a gear that meshes with the rack is provided at the output end of the third motor. A controller is fixed on the outer surface of the tension control device, and the output end of the controller is electrically connected to the third motor. The tension sensor is electrically connected to the controller.

[0008] As a further description of the above technical solution: the combined guide wheel is composed of two semi-ring wheels, and the combined guide wheel composed of the two semi-ring wheels is sleeved on the surface of the upper guide roller or the lower guide roller. A set of mounting blocks is welded to each pair of the surfaces of the upper guide roller and the lower guide roller, and each set of mounting blocks is provided with a semi-ring wheel. The mounting blocks and the semi-ring wheels are fixedly connected by screws.

[0009] As a further description of the above technical solution: a bushing is fitted on both ends of the lower guide roller, and the bushing is connected to the inner wall of the front tightening device or the rear tightening device.

[0010] As a further description of the above technical solution: the surface of the combined guide wheel is provided with a circular groove, the cross-section of which is an arc shape, and the size of the groove is adapted to the diameter of the steel wire.

[0011] As a further description of the above technical solution: the top surface of the tension control device has a rectangular opening corresponding to the rack, and a dovetail groove is provided on the inner side of the rectangular opening. A dovetail strip is provided on the side of the rack away from the feeding surface, and the dovetail strip is slidably connected to the dovetail groove in the rectangular opening.

[0012] As a further description of the above technical solution: the tension control device is generally L-shaped, and a fixing block is welded to the bottom of the tension control device, and the surface of the fixing block is provided with screw holes.

[0013] This utility model has the following beneficial effects: In this invention, a front-end tightening device and a rear-end tightening device are respectively installed at both ends of the base. When the first and second motors are started, they drive the corresponding upper guide rollers to rotate. With the auxiliary rotation of the lower guide rollers, the steel wire located in the grooves on the surface of the combined guide rollers obtains different speeds at the front-end and rear-end tightening devices. The motor controller sets the speed of the first motor to be greater than that of the second motor, resulting in a difference in the linear velocity of the steel wire before and after a certain production process, generating tension. Because the front end has a faster speed and the rear end has a slower speed, this speed difference causes the steel wire to be tightened, achieving a tightening effect and ensuring... The produced steel wire has excellent performance. Meanwhile, multiple tension control devices are installed on the base, and the tension sensor of each device is in contact with the steel wire. When the tension at a certain point on the steel wire is lower than required for production, the controller activates a third motor, which drives a gear to rotate. Since the gear meshes with a rack inside the tension control device, and the bottom of the rack is connected to a tension sensor, as the rack moves downwards within the tension control device, the roller of the tension sensor applies a downward force to the steel wire. This achieves the adjustment and control of the steel wire tension, facilitating real-time adjustment of the production line speed to ensure that the steel wire maintains appropriate tension throughout the entire production process.

The tension sensor 11 is electrically connected to the controller 21. Regarding the tension sensor 11, the third motor 17, and the controller 21, the control method of this utility model is automatic control through the controller 21. The control circuit of the controller 21 can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail. The first motor 4 and the second motor 5 are both servo motors and are equipped with motor controllers to control the speed of the first motor 4 and the second motor 5. Specifically, this is known prior art and will not be elaborated further. In one embodiment, the combined guide wheel 15 is composed of two semi-ring wheels, and the combined guide wheel 15 composed of the two semi-ring wheels is sleeved on the surface of the upper guide roller 12 or the lower guide roller 13. A set of mounting blocks 14 are welded to the surfaces of the upper guide roller 12 and the lower guide roller 13 in pairs, and each set of mounting blocks 14 is provided with a corresponding semi-ring wheel. The mounting blocks 14 and the semi-ring wheels are fixedly connected by screws. With this structure, it is easy to replace the combined guide wheel 15 of appropriate size as needed to meet the production requirements of steel wires of different diameters.

[0019] In one embodiment, a bushing is fitted at both ends of the lower guide roller 13, and the bushing is connected to the inner wall of the front tightening device 2 or the rear tightening device 3. The bushing facilitates the installation of the lower guide roller 13 and makes it easier for the lower guide roller 13 to rotate.

[0020] In one embodiment, the surface of the combined guide wheel 15 is provided with a circular groove 16, and the cross-section of the groove 16 is an arc-shaped structure. The size of the groove 16 is adapted to the diameter of the steel wire. The groove 16 is used to connect the combined guide wheel 15 and the steel wire.

[0021] In one embodiment, the top surface of the tension control device 7 has a rectangular opening 19 corresponding to the rack 9, and a dovetail groove is provided on the inner side of the rectangular opening 19.

[0023] Working principle: In use, the steel wire is first passed sequentially through the front tightening device 2 and the rear tightening device 3 of the base 1, and connected to the tension sensor 11 of the tension control device 7. As the first motor 4 and the second motor 5 are started, they drive the corresponding upper guide rollers 12 to rotate. With the auxiliary rotation of the lower guide roller 13, the steel wire located in the groove 16 on the surface of the combined guide wheel 15 obtains different speeds at the front tightening device 2 and the rear tightening device 3. By setting the speed of the first motor 4 to be greater than that of the second motor 5, the linear velocity of the steel wire before and after a certain production process is different, generating tension. Due to the front... The initial speed is faster, while the speed at the rear end is slower. This speed difference causes the steel wire to be tightened, achieving a tightening effect. When the tension at a certain point of the steel wire is lower than the production requirement, the third motor 17 is started, causing the third motor 17 to drive the gear 10 to rotate. Since the gear 10 is meshed with the rack 9 in the tension control device 7, and the bottom of the rack 9 is connected to the tension sensor 11, as the rack 9 moves downward in the tension control device 7, the roller of the tension sensor 11 applies a downward force to the steel wire, realizing the adjustment and control of the steel wire tension. This is beneficial for adjusting the speed of the production line in real time to ensure that the steel wire maintains appropriate tension throughout the entire production process.
