Description

Technical Field

[0001] The invention relates to the technical field of copper twisting machines, in particular to a high-speed copper twisting machine for twisting multiple copper wires with a torque elimination function. Background Art

[0002] Stranded wire is made by twisting single wires along the stranded wire bow and rotating them around the stranded wire axis at a constant angular velocity and moving the stranded wire forward at a uniform speed. Commonly used base materials are copper and aluminum. Copper and aluminum wires can be twisted into conductor cores of various specifications and cross-sections as well as different types of wires and cables.

[0003] For example, in the prior art, there is a conductor twisting machine with publication number CN116721813A, which is capable of eliminating torque. The twisting machine firstly realizes the parallel twisting of multiple copper wires through a twisting device, and then combines the different speed torsion shaping treatment of the twisted wires with the adjusting capstan. Although it can avoid the problem of torque generated when twisting multiple copper wires, the twisting device and the rotating sleeve in the adjusting capstan rotate at different speeds, that is, the rotation speed of the rotating sleeve in the adjusting capstan is greater than the rotation speed of the rotating sleeve of the twisting device, and the rotating disk and the rotating sleeve in the adjusting capstan rotate at the same speed, which is easy to generate continuous twisting force on the twisted wires during the shaping process, and thus it is difficult to achieve the effect of efficient twist-eliminating winding.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Example 1: Please refer to Figure 1-Figure 10 As shown, the following solution can be used to solve the problem that the stranded wire in the prior art is prone to continuous twisting force during the shaping process, making it difficult to achieve an efficient twist-free winding effect:

[0039] In the present embodiment, a high-speed copper stranding machine for paralleling multiple copper wires with a torque elimination function comprises a fixed seat 1, and a back-twisting stranding unit 2, a shaping wire fixing unit 3 and a winding unit 4 are sequentially arranged on the top of the fixed seat 1 from left to right. The back-twisting stranding unit 2 comprises a mounting seat 21 welded on the fixed seat 1, which is used to realize the rotatable installation of a rotating disk 22, and the rotating disk 22 is rotatably installed on the mounting seat 21, and a plurality of mounting plates 23 are arranged on one side of the rotating disk 22. The plurality of mounting plates 23 are distributed in a ring array relative to the axis of the rotating disk 22, or are distributed in a plurality of concentric circles from the inside to the outside, thereby realizing the paralleling and stranding of multiple copper wires;

[0040] A damping shaft 24 is rotatably connected between the mounting plate 23 and the rotating disk 22. The rotating disk 22 carries a plurality of winding wheels 42 for circumferential rotation. Combined with the fixed-line unit 3, the conveying clamping and fixing of the twisted wires makes the torsional force exerted on the single-strand copper wire during the rotation and unwinding of the unwinding wheel 25 prompting the unwinding wheel 25 carried by the mounting plate 23 to rotate by itself, thereby autonomously eliminating the torsional force generated by the single-strand copper wire during the winding process, avoiding the problem of breakage caused by the accumulation of torsional force, thereby improving the winding quality of the twisted wire. The damping shaft 24 can prevent the mounting plate 23 from rotating rapidly by itself through the damping rotation of the mounting plate 23. The mounting plate 23 is quickly detachably mounted with the unwinding wheel 25 for unwinding the copper wire, and is convenient for quickly replacing the unwinding wheel 25.

[0041] The shaping type wire fixing unit 3 includes a threading cylinder 31, which is used to convey and fix the stranded wire after multiple copper wires are combined, and a rotating cylinder 32 rotatably installed on the outside of the threading cylinder 31, which is used to drive the trapezoidal pushing seat 33 to move close to the stranded wire. Two groups of spiral grooves are symmetrically opened inside the threading cylinder 31, and trapezoidal pushing seats 33 sliding with the threading cylinder 31 are equidistantly installed in the spiral grooves along the length direction. By arranging the trapezoidal pushing seats 33 in the spiral grooves, the spiral distribution of the trapezoidal pushing seats 33 is realized, and then the stranded wire is subjected to multi-point all-round extrusion shaping treatment, and a trapezoidal clamping block 34 is movably installed on the trapezoidal pushing seat 33.

[0042] A wire twisting motor 26 for driving the rotating disk 22 to rotate is bolted onto the mounting seat 21, and is used to drive the rotating disk 22 to rotate rapidly. A wire ring 27 is provided on one side of the rotating disk 22, and a threading hole is provided on the wire ring 27. A connecting plate 28 is fixedly connected between the wire ring 27 and the rotating disk 22. The wire ring 27 and the threading hole are used to achieve uniform distribution of multiple copper wires, thereby improving the quality of the twisted wires. The connecting plate 28 is used to prompt the rotating disk 22 to drive the wire ring 27 to rotate, thereby achieving the effect of combining multiple copper wires to form a twisted wire.

[0043] The mounting plate 23 is symmetrically slidably connected with a clamping plate 29, and a centering rod 210 plugged with the pay-off wheel 25 is fixedly connected to the opposite side of the clamping plate 29, and a limit plate 211 is fixedly connected to the centering rod 210, and a bidirectional screw rod 212 threadedly connected with two sets of clamping plates 29 is rotatably connected to the mounting plate 23;

[0044] Both ends of the bidirectional screw rod 212 penetrate through the outside of the mounting plate 23 and are equipped with knobs, which facilitate the rotation of the bidirectional screw rod 212 and avoid changing the center of gravity of the mounting plate 23, which makes it difficult to rotate the mounting plate 23 better. The pay-off wheel 25 is placed between the two clamping plates 29 on the mounting plate 23, and the knob is turned to drive the bidirectional screw rod 212 to rotate. The bidirectional screw rod 212 drives the two groups of clamping plates 29 to move relative to each other, so that the centering rod 210 on the clamping plate 29 is inserted into the center hole of the pay-off wheel 25, thereby achieving a quick installation effect of the pay-off wheel 25.

[0045] A movable plate 213 is slidably connected to the centering rod 210, and a first tension spring 214 is fixedly connected between the movable plate 213 and the limiting plate 211. A Z-shaped rod 215 sliding with the limiting plate 211 is symmetrically mounted on the movable plate 213. A limiting groove sliding with the Z-shaped rod 215 is provided on the annular outer wall of the limiting plate 211 to avoid the problem of the movable plate 213 rotating. A plurality of protrusions 216 cooperating with the Z-shaped rod 215 and distributed in an annular shape are fixedly connected on both sides of the pay-off wheel 25.

[0046] After the centering rod 210 on the clamping plate 29 is inserted into the center hole of the pay-off wheel 25, the Z-shaped rod 215 on the movable plate 213 contacts the side of the pay-off wheel 25 under the tensile action of the first tension spring 214. When the pay-off wheel 25 rotates and pays off the wire, the multiple protrusions 216 intermittently contact and separate from the Z-shaped rod 215 under the tensile action of the first tension spring 214, thereby providing appropriate pay-off resistance for the pay-off wheel 25, ensuring the tightening effect of the single copper wire during the winding process, and further improving the uniformity and tightness of the twisted wire winding.

[0047] A support plate is symmetrically connected between the threading barrel 31 and the fixing seat 1 to realize the installation of the threading barrel 31, and a bunching guide sleeve 35 is mounted on both sides of the threading barrel 31. The bunching guide sleeve 35 is arranged to prevent the distance between multiple strands of copper wire from being too wide when entering the threading barrel 31 for winding, so that the copper wire is easily stuck between two adjacent sets of wire clamping wheels 38, thereby affecting the quality of the stranded wire;

[0048] The problem of large shaking caused by winding the stranded wire before passing through the threading barrel 31, which affects the service life of the electric push rod 36, is eliminated. The detachable clustering guide sleeve 35 is easy to replace according to the size of the stranded wire, thereby ensuring the paralleling effect of stranded wires of different diameters.

[0049] A plurality of installation cavities are provided on the inner walls at both ends of the threading barrel 31, and a U-shaped block 37 sliding therewith is connected to the installation cavity through an electric push rod 36, and a wire fixing clamp wheel 38 is rotatably installed in the U-shaped block 37. By setting a plurality of wire fixing clamp wheels 38 and an electric push rod 36, a mobile fixing effect of different sizes of stranded wires in the threading barrel 31 can be achieved.

[0050] A movable push column 310 is installed on one side of the trapezoidal pushing seat 33, and a second tension spring 311 is connected between the trapezoidal pushing seat 33 and the spiral groove. A fixed push column 312 that cooperates with the corresponding movable push column 310 is installed on the inner wall of the rotating cylinder 32. An inclined surface is provided on one side of the movable push column 310 and the fixed push column 312, so that when the fixed push column 312 contacts the movable push column 310, the movable push column 310 can be pushed to move close to the axis of the threading cylinder 31, thereby driving the trapezoidal pushing seat 33 to contact the stranded wire and stretch the second tension spring 311, so as to perform multi-point extrusion molding treatment on the stranded wire.

[0051] A transmission rod 313 is rotatably mounted on the mounting seat 21 and a side support plate, and a gear and a driving sprocket are mounted on the transmission rod 313. An outer gear ring meshing with the gear is fixedly connected to the rotating disk 22, and a driven sprocket is fixedly connected to the rotating cylinder 32. The driven sprocket and the driving sprocket are connected through a chain transmission.

[0052] During the rotation of the rotating disk 22, the meshing outer gear ring and the gear drive the transmission rod 313 to rotate in the opposite direction. The transmission rod 313, in conjunction with the active sprocket, the driven sprocket and the chain, drives the rotating cylinder 32 to rotate. The rotating rotating cylinder 32 drives the multiple fixed push pins 312 to rotate circumferentially, and after rotating a certain angle, they contact the movable push pin 310, forcing the movable push pin 310 to carry the trapezoidal push seat 33 to move.

[0053] The winding unit 4 includes a U-shaped seat 41 fixedly connected to the top of the fixed seat 1, and a winding wheel 42 is rotatably installed in the U-shaped seat 41. A winding motor 43 for driving the winding wheel 42 to rotate is bolted on the U-shaped seat 41. The single-strand copper wire on the pay-off wheel 25 is passed through the corresponding threading hole on the wire ring 27, and then multiple strands of copper wire are manually wound to form a stranded wire, which is passed into the threading cylinder 31 through the bundle guide sleeve 35 on one side, and then passed out through the bundle guide sleeve 35 on the other side and connected to the winding wheel 42. The U-shaped block 37 is driven to move by the electric push rod 36, so that multiple fixed wire clamping wheels 38 clamp and fix the stranded wire;

[0054] The twisting motor 26 drives the rotating disk 22 to rotate, and the rotating disk 22 carries multiple winding wheels 42 to rotate circumferentially, combined with multiple wire clamping wheels 38 to clamp and fix the twisted wire, and the winding motor 43 drives the winding wheel 42 to rotate to wind the twisted wire, thereby quickly winding multiple strands of copper wire. During the rotation and pay-off process of the pay-off wheel 25, the torque applied to the single strand of copper wire prompts the mounting plate 23 to carry the pay-off wheel 25 to rotate, thereby autonomously eliminating the winding torque.

[0055] Example 2: Please refer to Figure 8 and Fig. 9 As shown in the figure, the following solutions can be used to solve the problem of difficulty in further achieving efficient shaping treatment and inability to adapt to the treatment of strands of different diameters:

[0056] In this embodiment, the fixed wire fixing unit 3 includes a threading cylinder body 31 and a rotating cylinder 32 rotatably installed on the outside of the threading cylinder body 31. Two sets of spiral grooves are symmetrically opened inside the threading cylinder body 31, and trapezoidal pushing seats 33 sliding with the threading cylinder body 31 are equidistantly installed in the spiral grooves along their length direction, and trapezoidal clamping blocks 34 are movably installed on the trapezoidal pushing seats 33. The rotating rotating cylinder 32 causes multiple trapezoidal pushing seats 33 to move, and the trapezoidal pushing seats 33 drive the trapezoidal clamping blocks 34 to contact and clamp the stranded wire.

[0057] A concave groove is provided on the inclined surface of the trapezoidal push seat 33, and a convex block that slides with the concave groove is fixedly connected to the inclined surface of the trapezoidal clamping block 34, and a spring 39 is fixedly connected between one side of the convex block and the concave groove. The concave groove and the convex block are arranged to realize the connection between the trapezoidal push seat 33 and the trapezoidal clamping block 34, and the relative arrangement of the relative inclined surfaces of the two makes the movable push column 310 carry the continuous movement of the trapezoidal push seat 33, and the trapezoidal clamping block 34 is limited after contacting the stranded wire;

[0058] Promoting relative sliding between the trapezoidal pushing seat 33 and the trapezoidal clamping block 34, and promoting the trapezoidal clamping block 34 to move along the wide side direction of the movable pushing column 310, not only realizes the extrusion-type shaping processing of strands of different sizes, and achieves adaptive extrusion force adjustment for shaping of strands of different sizes, but also promotes the strands to undergo secondary multi-point extrusion-type shaping twisting in the threading cylinder 31, and the twisting direction is opposite to the strand winding direction, driving the strands to deflect, further enhancing the strand winding shaping effect, and when the trapezoidal clamping block 34 resets under the compression of the spring 39, the secondary twisted strands can naturally release the winding torque, avoiding the problem of difficulty in efficient twist-eliminating winding due to multi-stage twisting.

[0059] A movable push column 310 is installed on one side of the trapezoidal pushing seat 33, and a second tension spring 311 is connected between the trapezoidal pushing seat 33 and the spiral groove. A fixed push column 312 that cooperates with the corresponding movable push column 310 is installed on the inner wall of the rotating cylinder 32. The multiple fixed push columns 312 and the movable push columns 310 have a spiral distribution with the same spiral line, which enables the multiple fixed push columns 312 to contact the corresponding movable push columns 310 at the same time, thereby improving the twisting effect of the stranded wire.

[0060] Example 3: Please refer to Figure 1-Figure 10 As shown, the present invention also provides a method for using a high-speed copper stranding machine for multiple copper wires with a torque elimination function, comprising the following steps:

[0061] Step 1: Place the pay-off wheel 25 between the two clamping plates 29 on the mounting plate 23, turn the knob to drive the bidirectional screw rod 212 to rotate, and the bidirectional screw rod 212 drives the two sets of clamping plates 29 to move relative to each other, so that the centering rod 210 on the clamping plate 29 is inserted into the center hole of the pay-off wheel 25, and the Z-shaped rod 215 on the movable plate 213 contacts the side of the pay-off wheel 25 under the tension of the first tension spring 214, and then multiple pay-off wheels 25 are installed;

[0062] Step 2: Pass the single copper wire on the pay-off wheel 25 through the corresponding threading hole on the wire ring 27, and then manually wind the multiple copper wires to form a stranded wire, pass it into the threading cylinder 31 through the one-side bundle guide sleeve 35, and then pass it out through the other-side bundle guide sleeve 35, and connect it to the winding wheel 42, and drive the U-shaped block 37 to move through the electric push rod 36, so that the multiple wire clamping wheels 38 clamp and fix the stranded wire;

[0063] Step 3: The twisting motor 26 drives the rotating disk 22 to rotate, and the rotating disk 22 carries multiple winding wheels 42 to rotate in a circumferential direction, and the multiple wire clamping wheels 38 clamp and fix the twisted wires, and the winding motor 43 drives the winding wheel 42 to rotate to wind the twisted wires, thereby quickly winding the multiple strands of copper wires, and during the rotation and release of the pay-off wheel 25, the torque on the single strand of copper wire prompts the mounting plate 23 to carry the pay-off wheel 25 to rotate, thereby autonomously eliminating the winding torque;

[0064] During the pay-off wheel 25's rotation, the Z-shaped rod 215 under the tensile force of the first tension spring 214 intermittently contacts and separates from the plurality of protrusions 216 on the take-up wheel 42, so that the pay-off wheel 25 generates pay-off resistance, thereby ensuring the tightening effect of the single copper wire and improving the winding quality of the stranded wire.

[0065] Step 4: During the rotation of the rotating disk 22, the meshing outer gear ring and the gear drive the transmission rod 313 to rotate in the opposite direction. The transmission rod 313, in combination with the driving sprocket, the driven sprocket and the chain, drives the rotating cylinder 32 to rotate. The rotating rotating cylinder 32 drives a plurality of spirally distributed fixed push pins 312 to rotate circumferentially. After rotating a certain angle, the fixed push pins 312 contact the movable push pin 310, forcing the movable push pin 310 to move with the trapezoidal push seat 33. The trapezoidal push seat 33 drives the trapezoidal clamping block 34 to contact and clamp the stranded wire.

[0066] Step 5: With the continuous movement of the trapezoidal pushing seat 33 carried by the movable pushing column 310, and the limitation after the trapezoidal clamping block 34 contacts the stranded wire, the trapezoidal pushing seat 33 and the trapezoidal clamping block 34 are prompted to slide relative to each other, and with the help of the connection between the oblique surfaces of the two, the trapezoidal clamping block 34 is prompted to move horizontally. Combined with the contact and movement of several trapezoidal clamping blocks 34 with the stranded wire, the stranded wire is prompted to undergo a secondary multi-point extrusion shaping and twisting in the threading cylinder 31, and the twisting direction is opposite to the winding direction of the stranded wire. Later, through the separation of the fixed pushing column 312 and the movable pushing column 310, the trapezoidal pushing seat 33 is reset under the tensile force of the second tension spring 311, and the trapezoidal clamping block 34 is reset under the compression of the spring 39, to achieve intermittent torsion shaping. After completing one torsion shaping, the stranded wire that has been twisted twice can naturally release the winding torque.

[0067] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
