[0001] This utility model relates to the field of welding wire stranding technology, specifically a welding wire stranding device. Background Technology

[0002] Welding wire is a metal wire used as filler metal or as a conductive electrode in welding. In gas welding and tungsten inert gas welding, welding wire is used as filler metal. In submerged arc welding, electroslag welding and other molten electrode gas welding, welding wire is both filler metal and conductive electrode. Usually, multiple strands of welding wire need to be twisted together.

[0003] In practical use, existing wire stranding devices require the entire wire stranding reel to be replaced when the size of the wire changes to meet different needs. This replacement is inconvenient, time-consuming, labor-intensive, and costly. Therefore, there is an urgent need to improve the structure of the wire stranding device to perfect this equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a stranding device for welding wire, which can adapt to the needs of stranding welding wires of different sizes and specifications by changing the sleeves of different diameters, and does not require the replacement of the entire thick wire spool, thereby reducing the cost of use and improving the flexibility of use, and further improving the effect of use, so as to solve the problems in the current market mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire stranding device, comprising a wire stranding spool, wherein the wire stranding spool has multiple open slots inside, the open slots being evenly distributed around the circumference of the wire stranding spool, and a sleeve is provided inside the open slots, wherein... The movement direction of the sleeve is limited by a positioning mechanism inside the wire coil. An installation groove is provided inside the wire coil near the sleeve, and the sleeve is installed in the installation groove by a plug-in mechanism.

[0006] Preferably, the wire spool has positioning grooves on both sides near the opening groove, and the sleeve is fixedly connected with positioning protrusions at the positions corresponding to the positioning grooves.

[0007] Preferably, the positioning groove and the positioning protrusion have rectangular cross-sections, and a polished layer is provided at the contact points between the positioning groove and the positioning protrusion.

[0008] Preferably, the threaded reel has a threaded groove on the side near the mounting groove, a threaded rod is threadedly connected inside the threaded groove, a locking nut is sleeved on the outer end of the threaded rod, a connecting rod is provided on the side of the threaded rod away from the locking nut, a rotating groove is provided on the connecting rod corresponding to one end of the threaded rod, a rotating block is rotatably connected inside the rotating groove, the rotating block is fixedly connected to the end of the threaded rod, two insert rods are provided inside the mounting groove, each insert rod is rotatably connected to the connecting rod, a sliding groove is provided on the end of the mounting groove near the insert rod, a slider is slidably connected inside the sliding groove, the slider is fixedly connected to the insert rod, and a fixing groove is provided on the sleeve corresponding to the position of the insert rod.

[0009] Preferably, the rotating rods on both sides of the connecting rod are arranged in a figure-eight shape opposite each other.

[0010] Preferably, the contact area between the insertion rod and the fixing groove is provided with a frosted layer.

[0011] Preferably, the cross-sections of the groove and the slider are adapted to each other, and the internal dimensions of the groove match the external dimensions of the slider.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a sleeve. After the sleeve is moved into the opening groove, its installation direction is limited by a positioning mechanism. Rotating the threaded rod causes the connecting rod to move upward. The movement of the connecting rod causes the rotating rod to rotate, thereby moving the insert rod into the fixed groove and locking the sleeve in place. This device is easy to operate. By changing sleeves of different diameters, it can adapt to the needs of twisting welding wires of different sizes and specifications, without the need to replace the entire heavy wire spool. This reduces the cost of use, increases the flexibility of use, and further improves the performance.

[0013] This invention, by setting a positioning protrusion and a rotating block, aligns the positioning protrusion at the outer end of the sleeve with the positioning groove and moves the sleeve into the opening groove, thus limiting the movement direction of the sleeve and ensuring that the insertion rod and the fixing groove are on the same plane. When the threaded rod rotates, it forms a rotatable connection with the connecting rod through the rotating block, preventing the threaded rod from rotating and affecting the performance. Furthermore, when the rotating rod rotates and moves the insertion rod, the insertion rod can drive the slider to slide within the groove, thereby limiting the movement direction of the insertion rod and ensuring it smoothly enters the fixing groove. Simultaneously, a frosted layer is provided at the contact point between the insertion rod and the fixing groove, increasing the friction between them and preventing the insertion rod from wobbling freely within the fixing groove, which would affect its use.

[0017] Please see Figures 1 to 4 This utility model provides a technical solution: a wire stranding device, including a wire stranding spool 1, the wire stranding spool 1 having multiple open slots 2 inside, the open slots 2 being evenly distributed around the circumference of the wire stranding spool 1, and a sleeve 3 being provided inside the open slots 2. The movement direction of the sleeve 3 is limited by a positioning mechanism inside the wire spool 1. An installation groove 6 is provided inside the wire spool 1 near the sleeve 3. The sleeve 3 is installed in the installation groove 6 by a plug-in mechanism.

[0018] By setting the sleeve 3, after the sleeve 3 is moved into the opening groove 2 and its installation direction is limited by the positioning mechanism, the threaded rod 8 is rotated, which causes the connecting rod 9 to move upward. The movement of the connecting rod 9 can drive the rotating rod 13 to rotate, thereby driving the insertion rod 12 to move into the fixed groove 16 and clamping and fixing the sleeve 3. This device is relatively easy to operate. By replacing the sleeve 3 with different diameters, it can meet the needs of twisting welding wire of different sizes and specifications, and there is no need to replace the entire thick wire spool 1, which reduces the cost of use and improves the flexibility of use, further improving the effect of use.

[0019] Please see Figure 1The wire spool 1 has positioning grooves 4 on both sides near the opening groove 2. The sleeve 3 is fixedly connected to the positioning protrusion 5 at the position corresponding to the positioning groove 4. The positioning groove 4 and the positioning protrusion 5 have rectangular cross sections. The contact area between the positioning groove 4 and the positioning protrusion 5 is provided with a polished layer.

[0020] Align the positioning protrusion 5 at the outer end of the sleeve 3 with the positioning groove 4, and move the sleeve 3 into the opening groove 2. This can limit the movement direction of the sleeve 3, so that the insertion rod 12 and the fixing groove 16 are on the same plane. By setting a polishing layer, the positioning protrusion 5 can move more smoothly in the positioning groove 4.

[0021] Please see Figures 2 to 4 The threaded reel 1 has a threaded groove 7 on the side near the mounting groove 6. A threaded rod 8 is threadedly connected inside the threaded groove 7. A locking nut 17 is sleeved on the outer end of the threaded rod 8. A connecting rod 9 is provided on the side of the threaded rod 8 away from the locking nut 17. A rotating groove 10 is provided on the connecting rod 9 corresponding to one end of the threaded rod 8. A rotating block 11 is rotatably connected inside the rotating groove 10.

A slider 15 is slidably connected inside the sliding groove 14. The slider 15 is fixedly connected to the insert rod 12. A fixing groove 16 is provided on the sleeve 3 corresponding to the position of the insert rod 12.

[0022] Rotating the threaded rod 8 causes the connecting rod 9 to move upward. The movement of the connecting rod 9 causes the rotating rod 13 to rotate, thereby moving the insert rod 12 into the fixed groove 16 to lock and fix the sleeve 3. Then, the locking nut 17 can be sleeved on the outside of the threaded rod 8 to lock and limit the threaded rod 8.

[0023] Please see Figures 3 to 4 The rotating rods 13 on both sides of the connecting rod 9 are arranged in a figure-eight shape. The contact area between the insert rod 12 and the fixing groove 16 is provided with a frosted layer. The cross-sections of the sliding groove 14 and the slider 15 are matched. The internal dimensions of the sliding groove 14 match the external dimensions of the slider 15.

[0024] Working principle: When using this welding wire stranding device, firstly, select a sleeve 3 with a suitable diameter according to the size and specifications of the welding wire to be stranded. Then, align the positioning protrusion 5 at the outer end of the sleeve 3 with the positioning groove 4, and move the sleeve 3 into the opening groove 2. The movement direction of the sleeve 3 can be limited, so that the insertion rod 12 and the fixing groove 16 are on the same plane. Then, the rotatable threaded rod 8 causes the connecting rod 9 to move upward. The movement of the connecting rod 9 causes the rotating rod 13 to rotate, thereby moving the insert rod 12 into the fixed groove 16 to lock and fix the sleeve 3. This device is easy to operate. By replacing the sleeve 3 with different diameters, it can meet the needs of twisting welding wires of different sizes and specifications. Moreover, it does not require replacing the entire thick wire spool 1, which reduces the cost of use and increases the flexibility of use, further improving the effect of use.
