Description

Technical Field

[0001] The utility model belongs to the technical field of wire stranding machines, in particular to a constant force wire stranding machine. Background Art

[0002] A wire twisting machine is a mechanical device used to twist multiple wires into a single strand. It is widely used in the production of wires and cables. Through rotary twisting, it not only enhances the strength and flexibility of the wires, but also improves their conductivity. In some applications, rotary transformers twist the installation wires to improve their anti-interference capabilities. However, due to the thin diameter of the installation wires and the relatively weak solder joints between the installation wires and the coil winding, twisting the installation wires can easily transfer torque to the solder joints, causing stress on the solder joints and creating significant safety hazards. Furthermore, excessive twisting force can pose a safety risk to the installation wires themselves.

[0003] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0024] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts should fall within the scope of protection of the present invention.

[0025] like Figure 1 As shown, a constant force stranding machine in one embodiment of the present invention comprises a pay-off mechanism 1 and a stranding mechanism 2 . After the installation wire 6 is paid out by the pay-off mechanism 1 , it is stranded by the stranding mechanism 2 .

[0026] Specific, combined Figure 2 The pay-off mechanism 1 includes a base plate 10, both ends of which are provided with mounting blocks 11, a cylindrical guide rod 12 is connected between the two mounting blocks 11, and a slide 3 is provided on the base plate 10. The slide 3 is sleeved on the guide rod 12 and has a sliding hole 31 that cooperates with the guide rod 12. The slide 3 can move on the base plate 10 along the guide rod 12.

[0027] A platform surface 32 is provided on the slide 3, on which a stranded wire product 33 is placed and a fixing component 4 is provided on one side of the stranded wire product 33. An installation line 6 extends from the stranded wire product 33, and the fixing component 4 can fix the root of the installation line 6 to prevent the welding point of the installation line 6 from being subjected to stress and affecting the product performance.

[0028] The installation line 6 is subjected to a twisting force during the twisting process. If the twisting force is too large, the installation line 6 is easily damaged. To this end, an adjustment component is provided on the base plate 10. The adjustment component specifically includes a mounting frame 50 provided on the base plate 10, a fixed pulley 51 provided on the mounting frame 50, and an adjustment rope 52 connected to the slide 3. The adjustment rope 52 passes around the fixed pulley 51 and is connected to a weight block 53 at the end. During the twisting process, the gravity of the weight block 53 and the twisting force will act on the installation line 6 simultaneously. When the twisting force is too large, the slide 3 can move toward the twisting mechanism 2. When the twisting force is too small, the slide 3 will move away from the twisting mechanism 2 under the action of the weight block 53. The cooperation of the weight block 53 can adjust the force on the installation line 6 and protect the installation line 6 from excessive force.

[0029] Further, refer to Figure 3 The fixing assembly 4 includes two cylindrical fixing rods 40 mounted on the platform surface 32. Four fixing blocks 41 are mounted on the two fixing rods 40. In this embodiment, six installation wires 6 extend from the stranded wire product 33, with two fixing blocks 41 clamping and securing each pair of installation wires 6. Of course, in other embodiments, the number of fixing blocks 41 can also be two, three, or five. To better secure the installation wires 6 and reduce the possibility of interference between the installation wires 6 and affecting the twisting, the side surfaces of the fixing blocks 41 are provided with receiving slots 411 that cooperate with the installation wires 6.

[0030] The tops of the two fixing rods 40 are connected with a top plate 42, and a compression spring 43 is provided on the fixing rod 40. The compression spring 43 is located between the top plate 42 and the fixing block 41, and the compression spring 43 is in a compressed state and has the elastic force to continuously squeeze the fixing block 41, so that the fixing block 41 can clamp and fix the mounting line 6.

[0031] Further, refer to Figure 4 The wire twisting mechanism 2 includes a mounting base 20, which includes a support plate 201 and a fixed plate 202 mounted on the support plate 201. A main gear 21 is mounted on the fixed plate 202 via a rotating shaft. A power element 22 is mounted on the support plate 201 to drive the main gear 21. Preferably, the power element 22 is a motor. Three slave gears 23 are also mounted on the fixed plate 202 via a rotating shaft. The three slave gears 23 are evenly arranged around the main gear 21, and each slave gear 23 is provided with two wire twisting clamps 24 on its end face. In this embodiment, six mounting wires 6 extend from the stranded wire product 33, with each pair of mounting wires 6 corresponding to a corresponding slave gear 23. These two mounting wires 6 are secured to each other by two wire twisting clamps 24 on the slave gears 23. During stranding, three groups of mounting wires 6 can be twisted simultaneously, effectively improving stranding efficiency. Alternatively, the number of slave gears 23 can be set to one, two, four, five, or the like, depending on actual needs, and the number of wire twisting clamps 24 on the slave gears 23 can also be set to three, four, or five, or the like.

[0032] Specifically, refer to Figure 5 The wire twisting clamp 24 includes two clamping pieces 241 arranged opposite to each other. The ends of the two clamping pieces 241 are each provided with a through hole 242. The two clamping pieces 241 are connected by a locking piece 244 inserted into the through hole 242. Preferably, the through hole 242 on one of the clamping pieces 241 is a threaded hole 243, and the locking piece 244 is a screw that cooperates with the threaded hole 243. Before twisting the wires, the end of the installation wire 6 is first inserted between the two clamping pieces 241, and the screws are tightened to cause the two clamping pieces 241 to produce elastic deformation and move closer to each other until the installation wire 6 is clamped. Of course, in other embodiments, other methods can also be selected to make the clamping piece 241 clamp the installation wire 6, such as replacing the locking piece 244 with a bolt and a nut, and achieving the purpose of deforming the clamping piece 241 and clamping the installation wire 6 through the cooperation of the bolt and the nut.

[0033] In summary, the present invention first secures the base of the mounting wires 6 via the fixing assembly 4, preventing excessive stress on the welding points between the mounting wires 6 and the coil winding during the twisting process, thereby ensuring product performance. Secondly, the weight block 53 provides a constant gravity, allowing the slide 3 to move on the guide rod 12 under the action of gravity and the twisting force, thereby adjusting the force applied to the mounting wires 6 and preventing excessive stress on the mounting wires 6. Finally, the twisting mechanism 2 allows three groups of mounting wires 6 to be twisted simultaneously, achieving high efficiency.
