Description

Technical Field

[0001] The present invention belongs to the technical field of twisted wire processing, and specifically relates to a cold-welded twisted wire manufacturing device. Background Art

[0002] Twisted wire, as a typical form of cable construction, is usually carefully woven from two or more metal wires. In this process, each wire is orderly arranged and twisted along a shared central axis in its own unique way, forming a spiral interwoven structure with high strength. In the process of twisting wire, twisted wire manufacturing equipment is required.

[0003] For example, the existing publication (announcement) number is "CN116140504A", which is a multi-strand twisted wire manufacturing equipment based on cold welding technology, including: a wire feeding mechanism, the wire feeding mechanism includes a support plate, a rotating unit and a wire release disk, the rotating unit is placed on the support plate, the wire release disk is multiple and all are arranged on the rotating unit, the wire feeding mechanism is used to respectively transmit the metal wires on the wire release disk; a wire twisting mechanism, the wire twisting mechanism includes an extrusion part and a cleaning part, the cleaning part is used to clean the metal wire, and the extrusion part is used to twist and extrude all the metal wires so that all the metal wires are twisted to form a strand of twisted wire; a wire collecting mechanism, the wire collecting mechanism is used to collect the formed twisted wire.

[0004] The above-mentioned wire twisting equipment has the following defects: (1) Due to the different hardness, toughness and ductility of different metal wires (such as iron and copper), when twisting metal wires of different materials, it is necessary to adjust the tightness of the twisted wires to optimize the stress distribution between the metal wires. (2) The existing wire twisting equipment has separate wire release and wire twisting, which makes it difficult to synchronously control the speed of wire twisting and wire release, resulting in inaccurate control of the wire twisting tension. Utility Model Content

[0005] The purpose of this scheme is to provide a cold welding twisted wire manufacturing equipment to solve the problem that the existing twisted wire equipment is not convenient for synchronously controlling the twisting and wire releasing speeds.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a cold welding twisted wire manufacturing device, comprising a twisting device and a wire collecting device arranged at the rear end of the twisting device, wherein the twisting device comprises:

[0007] A fixing ring, wherein the fixing ring is erected on the ground through a supporting column;

[0008] A first wire feeding roller, the first wire feeding roller is arranged at the center of the fixing ring, and the first wire feeding roller is connected to the fixing ring through a support rod;

[0009] A gear ring, the gear ring is coaxially rotatably connected with the fixed ring;

[0010] a second wire feeding roller, the second wire feeding roller being arranged on the inner wall of the gear ring;

[0011] A driving assembly is used to drive the gear ring to rotate.

[0012] The principle of this scheme is that the wire twisted by the twisting device is pulled by the wire taking-up device, and during the twisting process, the gear ring is driven by the driving component to rotate circumferentially, thereby driving the second wire feeding roller on the gear ring to rotate synchronously, and then the wire on the second wire feeding roller is wound around the wire fed by the first wire feeding roller. At the same time, the speed of the driving component can be controlled to synchronously control the speed of wire release and twisting, thereby adjusting the wire twisting tension.

[0013] The technical effects of this solution are: (1) By controlling the rotation speed of the gear ring through the drive component, the tension of the wire can be controlled during the winding process, solving the problem that the existing equipment is difficult to conveniently adjust the tightness of the twisted wire. (2) The combination of the twisting device and the wire unwinding device can make the control of the twisted wire tension more precise, and the wire unwinding speed and the twisting speed can be controlled synchronously. In the process of continuous wire unwinding and twisting, it is easier to maintain parameters such as the wire spacing and the twisting pitch.

[0014] Furthermore, the driving assembly includes a motor and a gear fixedly connected to an output end of the motor, and the gear is meshed with a gear ring.

[0015] The technical effect of this solution is that the gear is driven to rotate by the motor, thereby rotating the gear ring and adjusting the twisting speed.

[0016] Furthermore, the motor is a motor with a speed regulation function.

[0017] The technical effect of this solution is that the rotation speed of the gear ring is controlled by the motor, thereby controlling the twisting speed.

[0018] Furthermore, the gear ring is connected to a symmetrically arranged first support arm, the first support arm is rotatably connected to a second support arm, and the second wire feeding roller is rotatably connected to the second support arm.

[0019] The technical effect of this solution is that the angle of the second wire feeding roller is adjusted by rotating the second support arm. By tilting the angle of the second wire feeding roller, the tightness of the winding of the wire on the second wire feeding roller and the wire on the first wire feeding roller is controlled. When the second wire feeding roller rotates in the wire feeding direction, the wire fed by the second wire feeding roller and the wire fed by the first wire feeding roller are wound more loosely; when the second wire feeding roller rotates in the opposite direction, the wire fed by the second wire feeding roller and the wire fed by the first wire feeding roller are wound more tightly.

[0020] Furthermore, the first supporting arm is provided with a through slot, and a bolt for locking the second supporting arm is arranged in the through slot.

[0021] The technical effect of this solution is that the rotation angle of the second support arm is locked by the bolt, and the through groove provides positioning and guiding functions for the movement of the bolt.

[0022] Furthermore, there are multiple second wire feeding rollers, and the multiple second wire feeding rollers are equidistantly distributed around the center of the gear ring.

[0023] The technical effect of this solution is that the multiple second wire feeding rollers can provide wires respectively, and during the wire twisting process, the wires can be evenly wrapped around the wire fed by the first wire feeding roller from multiple directions.

[0024] Furthermore, the drive motor of the wire collecting device is arranged in cooperation with the motor.

[0025] The technical effect of this solution is to control the rotation speed of the drive motor to be consistent with that of the motor, so that the speed of wire feeding, wire twisting and wire collecting are consistent, thereby avoiding the wire being too tight or too loose due to speed mismatch.

The fixed ring 11 is erected on the ground through the support column. The first wire feeding roller 12 is arranged at the center position of the fixed ring 11, and the first wire feeding roller 12 is connected to the fixed ring 11 through a group of symmetrically arranged support rods 121. The support rods 121 are equivalent to reinforcing ribs, which not only enhance the strength of the fixed ring 11, but also provide support for the first wire feeding roller 12. The first wire feeding roller 12 is rotatably connected to the support rods 121.

[0035] See also Figure 3 and Figure 4, also includes a gear ring 13 coaxially rotatably connected to the fixed ring 11, the inner wall of the gear ring 13 is provided with 8 second wire feeding rollers 14, the 8 second wire feeding rollers 14 are equidistantly distributed around the center of the gear ring 13, the 8 second wire feeding rollers 14 can provide wires respectively, and in the process of twisting wires, the wires can be evenly wrapped around the wires sent out by the first wire feeding roller 12 from multiple directions, and also includes a driving assembly 15 for driving the gear ring 13 to rotate, the driving assembly 15 includes a motor 151 and a gear 152 coaxially fixedly connected to the output end of the motor 151, the motor 151 is a servo motor, and the electrical box is connected to a PID controller, the gear 152 is meshed with the gear teeth of the gear ring 13, and the wire twisted by the wire twisting device 1 is pulled by the wire taking-up device 2. In the process of twisting, the gear ring 13 is driven to rotate circumferentially by the motor 151, thereby driving the second wire feeding rollers 14 on the gear ring 13 to rotate synchronously, and then the wire on the second wire feeding roller 14 is wound around the wire sent out by the first wire feeding roller 12. By controlling the rotation speed of the motor 151 through the PID controller, the rotation speed of the gear ring is controlled, and the tension control during the twisted wire winding process can be achieved.
