[0032] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0033] Embodiment 1

[0034] like Figures 1 to 12 As shown, an automatic high-speed stranding machine for stranding ultra-fine tungsten wire strands includes a pay-off frame 1, a straightening and traction mechanism 3, and a winding mechanism 4. The pay-off frame 1 is provided with a plurality of pay-off components 5. The right end of the pay-off frame 1 is provided with an anti-breaking mechanism 6. The anti-breaking mechanism 6 includes a support frame 61, an adjustment component 62 arranged on the support frame 61, and an induction component 63 arranged at the right end of the adjustment component 62. The straightening and traction mechanism 3 includes a wire die frame 31, a rotating drum 32 rotatably arranged on the wire die frame 31, and a sensor component 63 arranged on the right end of the sensor component 63. The straightening assembly 33 in the rotating drum 32 and the traction assembly 34 arranged in the rotating drum 32, the winding mechanism 4 includes a placement frame 41, a wire-receiving drum 42 rotatably arranged on the placement frame 41, a sliding assembly 43 arranged in the wire-receiving drum 42 and a wire-receiving assembly 44 arranged in the wire-receiving drum 42, the wire-releasing assembly 5 eliminates the tension of the tungsten wire by means of hysteresis braking, and senses the tightness of the tungsten wire through the sensing assembly 63 to drive the adjusting assembly 62 to slide up and down to adjust the tightness of the tungsten wire to prevent the tungsten wire from breaking.

[0035] It is worth mentioning here that the tension of the tungsten wire is eliminated by the pay-off component 5 through hysteresis braking, the adjustment component is driven by the induction component 63 to slide up and down to adjust the tightness of the tungsten wire to prevent the tungsten wire from breaking, and the straightening component 33 is used to straighten the twisted tungsten wire to eliminate stress, thereby improving production efficiency, ensuring that the single wire will not break or drift when the machine rotates at high speed, and the twisting pitch is constant and precise.

[0036] like Figure 2 , Figure 3 As shown, the pay-off assembly 5 includes a pay-off drum 51 rotatably arranged on the pay-off frame 1, a pay-off roller 52 rotatably arranged in the pay-off drum 51, and a hysteresis brake 53 arranged at the end of the pay-off roller, and the other end of the pay-off roller 52 is provided with a clamping assembly 54, and the clamping assembly 54 includes a clamping tooth 541 arranged on the pay-off roller 52, a fixing member 542 arranged on the pay-off drum 51, and a clamping member 543 slidably arranged on the fixing member 542, and a spring is arranged between the clamping member 543 and the fixing member 542.

[0037] In this example, the pay-off assembly 5 is driven to rotate by a synchronous belt and a driving motor, and the pay-off roller 52 is clamped in the pay-off drum 51 by fixing the clamping teeth 541 through a clamping member 543 .

[0038] like Figure 4 , Figure 5 As shown, the adjustment component 62 includes a fixed plate 621 arranged on the support frame 61, two left and right guide wheels 622 rotatably arranged in the fixed plate 621, and a sliding wheel 623 slidably arranged in the fixed plate 621, a plurality of circular grooves 624 are opened on the fixed plate 621, a sliding groove 625 is opened in the middle part of the circular groove 624, a cylinder body a626 is arranged on one side of the sliding groove 625, an oil delivery channel a627 is opened between the cylinder body a626 and the fixed plate 621, and a piston a628 is arranged on the side of the sliding wheel 623 close to the cylinder body a626.

[0039] like Figure 4 , Figure 6 As shown, the induction component 63 includes a gathering disk 631 arranged at the right end of the fixed disk 621 and a conductive wire coil 632 slidably arranged in the gathering disk 631, the gathering disk 631 is provided with a plurality of through grooves 633 corresponding to the circular grooves 624, a cylinder body b634 is provided on one side of the through groove 633, a piston b635 is provided on the conductive wire coil 632, and the piston b635 is slidably arranged in the cylinder body b634, a return spring 636 is provided between the conductive wire coil 632 and the through groove 633, an oil delivery channel b637 is provided between the cylinder body b634 and the gathering disk 631, and an oil delivery pipe 638 is connected between the oil delivery channel b637 and the oil delivery channel a627.

[0040] In this example, the tightening of the tungsten wire drives the conductor coil 632 to move in respective directions, thereby driving the piston b635 to squeeze the hydraulic oil in the cylinder b634, and the hydraulic oil is transported to the cylinder a626 through the oil channel a627 via the oil channel b637 and the oil pipe 638. The rising level of the hydraulic oil squeezes the piston a628, thereby driving the sliding wheel 623 to move upward, so that the tungsten wire is relaxed to prevent it from breaking; the gathering disk 631 allows the tungsten wire to be gathered in advance to prevent it from breaking.

[0041] like Figure 8 As shown, the straightening assembly 33 includes a vertical straightener 331 disposed in the left cavity of the rotating drum 32 and a horizontal straightener 332 disposed in the left cavity of the rotating drum 32 .

[0042] In this example, the stress in the twisted tungsten wire is eliminated by the vertical straightener 331 and the horizontal straightener 332 and the tungsten wire is straightened for output.

[0043] like Figure 8 As shown, the traction assembly 34 includes a traction wheel a341 arranged in the right cavity of the rotating drum 32 and a traction wheel b342 arranged in the right cavity of the rotating drum 32. The rear ends of the traction wheel a341 and the traction wheel b342 are provided with a servo motor and a planetary reduction box.

[0044] In this example, the speed of tungsten wire conveying is adjusted by traction wheel a341, traction wheel b342, servo motor and planetary reduction box.

[0045] like Fig. 9 , Fig.10 As shown, the wire take-up assembly 44 includes a driving member 441 rotatably disposed in the wire take-up drum 42 , a synchronous belt 442 driven by the driving member 441 , and a wire take-up roller 443 driven by the synchronous belt 442 , and a reducer 444 is disposed on the other side of the wire take-up roller 443 .

[0046] In this example, the driving member 441 drives the synchronous belt 442 to rotate, thereby driving the take-up roller 443 to reel in the tungsten wire, and the speed is slowed down by the reducer 444 to drive the screw rod 431 to rotate, thereby driving the sliding block 433 to slide back and forth on the screw rod 431, so that the tungsten wire is reeled in more smoothly.

[0047] like Fig. 9 As shown, the sliding assembly 43 includes a screw rod 431 driven by a reducer 444 , a guide rod 432 disposed in the wire take-up drum 42 , and a sliding block 433 driven by the screw rod 431 .

[0048] In this example, the screw rod 431 is a reciprocating screw rod.

[0049] like Figure 7As shown, a support plate 311 is provided at the left end of the wire mold frame 31, and a wire break protector 7 and a gatherer 8 are provided on the support plate 311 in sequence from left to right.

[0050] In this example, the broken tungsten wire is sensed by the wire break protector 7, so that the entire device is shut down to prevent the tungsten wire from twisting. The tungsten wire can be better twisted by the gatherer 8 to prevent the twisting angle from being too large and causing breakage.

[0051] The working process is as follows:

[0052] The clamping teeth 541 are manually fixed by the clamping member 543 so that the pay-off roller 52 is clamped in the pay-off drum 51, and the pay-off assembly 5 is driven to rotate by the synchronous belt and the driving motor;

[0053] The rotating drum 32 and the wire take-up drum 42 are driven to rotate by the synchronous belt and the driving motor, and the synchronous belt 442 is driven to rotate by the driving member 441, thereby driving the wire take-up roller 443 to reel the tungsten wire, and the speed is slowed down by the reducer 444 to drive the screw rod 431 to rotate, thereby driving the sliding block 433 to slide back and forth on the screw rod 431, so that the tungsten wire is taken up more smoothly;

[0054] The stress in the twisted tungsten wire is eliminated and straightened by the vertical straightener 331 and the horizontal straightener 332, and the speed of the tungsten wire conveying is adjusted by the traction wheel a341, the traction wheel b342 servo motor and the planetary reduction box;

[0055] The tightening of the tungsten wire drives the conductor coil 632 to move in respective directions, thereby driving the piston b635 to squeeze the hydraulic oil in the cylinder b634. The hydraulic oil is transported to the cylinder a626 through the oil channel a627 via the oil channel b637 and the oil pipe 638. The rising level of the hydraulic oil squeezes the piston a628, thereby driving the sliding wheel 623 to move upward, thereby relaxing the tungsten wire and preventing it from breaking.

[0056] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art under the technical guidance of the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
