Description

Technical Field

[0001] This invention relates to the field of cold heading machine feeding technology, and more specifically to an auxiliary take-up device for coiled wire used in cold heading machines. Background Technology

[0002] In the field of new energy vehicle component manufacturing, cold heading machines are key equipment for achieving the plastic forming of metal wire, and are widely used in the mass production of standard parts, fasteners, and various structural components. During production, wire is typically supplied in coil form and continuously unwound via an uncoiler. In actual production, coiled wire often remains unused, requiring the remaining wire to be removed from the uncoiler for reuse to meet subsequent production needs.

[0003] Currently, in cold heading production, the collection of partially used, loosely coiled wire mainly relies on manual labor. The common practice is that after production pauses, operators manually gather the coiled wire from the uncoiler, requiring multiple people to work together, using simple tools to organize the wire, then manually bundling and securing it, and finally using overhead cranes or forklifts to transport the coiled wire to the storage area. This solution, relying solely on manual labor and simple tools, is widely used in small-batch production within the industry.

[0004] Although manual collection is feasible under certain conditions, it has the following significant drawbacks:

[0005] 1. High labor intensity and low efficiency: For cold heading steel wire with large diameter and high hardness, the coil weight is large and the elasticity is strong. Manual gathering and bundling is extremely physically demanding and time-consuming, which seriously affects production.

[0006] 2. Significant safety hazards: During manual operation, loose wires are prone to springing off or slipping, which may cause pinching, scratches, or even more serious mechanical injuries to operators. Furthermore, improper coordination when multiple people are working together can easily lead to safety accidents.

[0007] 3. Unstable winding quality: Relying entirely on manual experience makes it difficult to guarantee the tightness and neatness of the coiled wire, which can easily lead to scratches and deformation on the wire surface, affecting the smoothness of wire feeding and the forming quality when used again.

[0008] 4. Lack of dedicated auxiliary equipment: In the existing technology, there is no mature and dedicated mechanism or equipment integrated into the cold heading machine to assist in the mechanized completion of the coiled wire collection operation, which has resulted in this link being in a state of inefficient and high-risk manual operation for a long time.

[0009] Therefore, there is an urgent need for a device that can be used in conjunction with a cold heading machine to solve the problems of high labor intensity, low efficiency, and operator safety during the wire gathering process. Summary of the Invention

[0010] To address this issue, the present invention provides an auxiliary winding device for cold heading machines to solve the problem that existing winding wire winding processes are prone to loosening and deformation, affecting subsequent processing and operator safety.

[0011] To achieve the above objectives, the embodiments of the present invention provide the following technical solutions:

[0012] An auxiliary take-up device for coiled wire in a cold heading machine includes:

[0013] A transverse support with a U-shaped structure, the U-shaped structure including an integrally formed top plate and two side plates, the transverse support being detachably and upside down installed on the uncoiler crossbeam and being movable along the length direction of the uncoiler crossbeam;

[0014] The gathering actuator includes a fixed tube fixedly mounted on the transverse support and a blocking rod detachably connected to the fixed tube. The blocking rod is used to push the loose coiled wire on the uncoiler to gather it together as the transverse support moves toward the side closer to the coiled wire.

[0015] The driving traction mechanism includes a fixedly installed power unit and a traction unit connected between the power unit and the transverse support. The power unit drives the transverse support to move along the length direction of the uncoiling machine beam toward the side closer to the coiled wire through the traction unit.

[0016] Furthermore, the fixing tube is disposed on the periphery of the transverse support, and the axis of the fixing tube is perpendicular to the axis of the uncoiling machine beam. At least two fixing tubes are provided, and the fixing tube is provided with a plurality of first pin holes spaced apart along its axial direction.

[0017] One end of the barrier rod can be inserted into the fixed tube, and the rod body at the insertion end is provided with a plurality of second pin holes that are adapted to the first pin hole along its axial direction. The locking member passes through the first pin hole and the second pin hole to fix and adjust the position of the barrier rod and the fixed tube. The other end is provided with a plurality of third pin holes along its axial direction.

[0018] Furthermore, it also includes a guide and anti-deviation mechanism, which includes a first rubber roller, a second rubber roller, a third rubber roller, and a fourth rubber roller. The first rubber roller is detachably disposed at the open end of the transverse support and is used to contact the lower surface of the uncoiler beam. The second rubber roller is fixedly disposed at the top plate of the transverse support and is used to contact the upper surface of the uncoiler beam. The third rubber roller and the fourth rubber roller are symmetrically disposed at the two side plates of the transverse support and are used to contact the two side surfaces of the uncoiler beam.

[0019] Furthermore, the transverse support is provided with lifting lugs for hoisting.

[0020] Furthermore, the drive traction mechanism includes two symmetrically arranged power units and traction units. The power units are fixedly installed on the side of the uncoiler frame away from the transverse axis, and the traction units pull the transverse support along the uncoiler crossbeam to the side closer to the uncoiler frame.

[0021] Furthermore, the power unit includes a motor and a clamping shaft. The motor is fixedly mounted on the side of the uncoiler frame away from the uncoiler crossbeam. The motor shaft of the motor is connected to the clamping shaft for transmission. The traction unit includes a wire rope. One end of the wire rope is fixedly mounted on the clamping shaft, and the other end passes through the third pin hole and is fixed to the blocking bar.

[0022] Furthermore, the guide anti-deviation mechanism also includes a pull ring, which is fixedly disposed on the side of the uncoiling machine frame, and the traction unit passes through the pull ring.

[0023] Furthermore, the pull ring and the barrier bar are made of 45 steel.

[0024] Furthermore, the clamping spool is made of 45 steel.

[0025] Furthermore, the transverse support is made of aluminum alloy.

[0026] Compared with the prior art, this application has at least the following beneficial effects:

[0027] 1. By setting up a power transmission system consisting of a drive traction mechanism and a transverse support, the heavy manual labor of pushing, pulling, and gathering, which relied entirely on manpower, is replaced. By simply controlling the drive traction mechanism, the transverse support equipped with a stop bar can automatically move along the uncoiler beam, quickly gathering loose coils, reducing operation time and fundamentally improving production efficiency.

[0028] 2. The device uses a mechanical structure to gather the wires, eliminating the need for operators to directly contact the heavy and easily spring-backed loose wires. This completely avoids safety accidents such as pinching and scratching that may occur due to improper manual operation in existing technologies. The safety of the working environment is significantly improved, effectively protecting the safety of operators and eliminating potential personal injury hazards.

[0029] 3. During movement, the barrier applies a uniform and continuous pushing force to the wire, which can smoothly and orderly gather loose coils into a tight roll. The gathered roll has a regular shape, which is convenient for secure bundling. In this process, it avoids scratches or deformation of the wire surface that may be caused by rough handling, thus ensuring the quality of wire reuse. Attached Figure Description

[0043] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] like Figures 1-5 As shown in the figure, this invention discloses an auxiliary take-up device for coiled wire in a cold heading machine, including a transverse support 100, a gathering execution mechanism, a drive traction mechanism, and a guide anti-deviation mechanism. These mechanisms work together to achieve the gathering and take-up of coiled wire. Its overall structure and usage instructions are as follows:

[0045] In this embodiment, the transverse support 100 has a U-shaped structure, which is integrally formed by the top plate and two side plates. It is installed on the uncoiler beam 500 in a detachable inverted manner and can move along the length of the uncoiler beam 500. Preferably, the transverse support 100 is made of aluminum alloy, which is lightweight, corrosion-resistant and has sufficient strength to meet the usage requirements. At the same time, the transverse support 100 is also provided with lifting lugs 405 for hoisting and disassembling the device.

[0046] The converging actuator includes a fixed tube 200 fixedly mounted on the transverse support 100 and a stop bar 300 detachably connected to the fixed tube 200. The fixed tube 200 is located around the periphery of the transverse support 100, with its axis perpendicular to the axis of the uncoiling beam 500, and at least two tubes are provided to ensure converging stability. Further, the fixed tube 200 has multiple first pin holes 201 spaced apart along its axial direction; one end of the stop bar 300 is detachably inserted into the fixed tube 200, and the inserted end has multiple second pin holes 301 spaced apart along its axial direction that mate with the first pin holes 201. By simultaneously passing through the first pin holes 201 and the second pin holes 301 with a locking element, the position of the stop bar 300 and the fixed tube 200 can be fixed and adjusted. Preferably, the locking element is a pin or a screw. The other end of the barrier bar 300 is provided with a plurality of third pin holes 302 at intervals along the axial direction for connecting the drive traction mechanism. Preferably, the barrier bar 300 is made of 45 steel and wrapped with a rubber layer, which can reduce the wear on the surface of the wire during the process of pushing the wire coil to gather.

[0047] The guiding and anti-deviation mechanism includes a first rubber roller 401, a second rubber roller 402, a third rubber roller 403, and a fourth rubber roller 404. The first rubber roller 401 is detachably bolted to the open end of the transverse support 100 and contacts the lower surface of the uncoiler beam 500. The second rubber roller 402 is fixedly mounted on the top plate of the transverse support 100 and contacts the upper surface of the uncoiler beam 500. The third and fourth rubber rollers 403 and 404 are symmetrically arranged on the two side plates of the transverse support 100 and contact the two side surfaces of the uncoiler beam 500, respectively. These four sets of rubber rollers constitute a guiding and anti-deviation constraint, ensuring smooth and stable movement of the transverse support 100 without swaying, and the rubber material also prevents scratches on the beam surface.

[0048] The drive traction mechanism includes two symmetrically arranged power units and traction units. The power units are fixedly installed on the side of the uncoiler frame opposite to the transverse axis. The traction units pull the transverse support 100 along the uncoiler crossbeam 500 to the side closer to the uncoiler frame. Preferably, the traction unit is a wire rope 602, a chain, a belt, etc. In this embodiment, a wire rope 602 is used. The power unit includes a motor 600 and a clamping shaft 601. The motor 600 is fixed to the side of the uncoiler frame away from the coiler crossbeam 500. The motor shaft of the motor 600 is connected to the clamping shaft 601. One end of the wire rope 602 is wound and fixed to the clamping shaft 601, and the other end passes through a pull ring 406 on the side of the uncoiler frame, then through a suitable third pin hole 302 on a selected and fixed stop bar 300, and finally is fixedly connected to the stop bar 300. By selecting different third pin holes 302 on the stop bar 300 to fix the wire rope 602, the optimal traction effect can be achieved. Preferably, the clamping shaft 601 and the pull ring 406 are made of 45# steel to enhance wear resistance. The two symmetrically arranged systems provide balanced traction force and prevent the transverse support 100 from twisting during movement.

[0049] In the above embodiment, the U-shaped transverse support 100 is first placed upside down on the uncoiler beam 500 to ensure that the transverse support 100 can slide smoothly along the length of the uncoiler beam 500. Then, the guide anti-deviation mechanism is installed. The first rubber roller 401 is fixed to the open end of the transverse support 100 with bolts and contacts the lower surface of the uncoiler beam 500. At the same time, the second rubber roller 402 contacts the upper surface of the beam 500. The third rubber roller 403 and the fourth rubber roller 404 are installed on the two side plates of the transverse support 100, respectively, and are in close contact with both sides of the beam 500 and can rotate flexibly. Then, according to the looseness of the coiled wire to be collected, the extension length of the barrier bar 300 relative to the transverse support 100 is adjusted. Alternatively, a barrier bar 300 of suitable length can be selected as needed. Specifically, by selecting different first pin holes 201 on the alignment fixing tube 200 and different second pin holes 301 on the barrier bar 300, the locking device is inserted to complete the fixation. One or more barrier bars 300 can be installed as needed. Finally, the wire rope 602 is passed through the pull ring 406 and the third pin hole 302 in sequence to complete the fixation at both ends and ensure that the tension of the wire rope is moderate and there is no slack. After assembly, the gathering operation can be started. In use, the motor 600 is turned on, and the motor shaft drives the clamping shaft 601 to rotate, thereby winding the wire rope 602. Under the guidance of the pull ring 406, the wire rope 602 pulls the transverse support 100 to move stably along the uncoiling beam 500 towards the side closer to the coiled wire. The barrier bar 300, which moves forward with the transverse support 100, will push the loose and outwardly expanded coiled wire on the uncoiling machine to gather towards one side of the uncoiling machine until the wire is restored to a neat and compact state. After the wires are gathered, turn off the motor 600. First, disconnect the connection between the wire rope 602 and the barrier bar 300. Then, remove the first rubber roller 401 from the transverse support 100. Finally, use a hoist to remove the entire transverse support 100 from the uncoiler beam 500 using the lifting lugs 405 to complete the operation.

[0050] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
