Description

Technical Field

[0001] This utility model relates to the field of welding wire processing technology, specifically a device for preventing wire tangling after welding wire annealing. Background Technology

[0002] With the increasing demand for lightweight construction machinery and coal mining machinery, the strength of steel plates has reached 1300 MPa, and the tensile strength of the weld metal of welding wire has also increased. Currently, the highest strength welding material commonly used in the market is 1000 MPa grade welding wire, whose tensile strength of weld metal can be greater than 1000 MPa. The welding wire adopts a multi-alloy strengthening system, which makes the welding wire itself strong. It cannot be drawn into shape in one go and needs to undergo stress relief annealing in the middle.

[0003] After annealing, iron oxide scale will be generated on the surface of the welding wire. Therefore, it needs to be removed by a belt sander during further drawing. In actual production, in order to make the sanding effect more beneficial, the diameter of the wire guide groove in the sander is only slightly larger than that of the welding wire. During the wire feeding process, the welding wire is prone to deviation due to the tension and often falls out of the wire guide groove of the belt sander, causing unnecessary scratches and irreversible damage to the subsequent drawing die and the quality of the finished product.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a device for preventing wire tangling after annealing of welding wire, including a vertical rod 1, which is configured as a hollow structure and has grooves 2 on its surface for the passage of welding wire. A base 3 is fixedly installed on the surface of the vertical rod 1, and the surface of the base 3 is provided with a vertical anti-tangle structure and a horizontal anti-tangle structure.

[0024] The vertical anti-tangle structure includes a first substrate 4, a first vertical limiting wheel 5, a second vertical limiting wheel 6, a first connecting shaft 7, and a first sliding groove 8. The first sliding groove 8 is disposed on the surface of the first substrate 4. The three first vertical limiting wheels 5 are equidistantly rotatably connected to the surface of the first substrate 4. The second vertical limiting wheel 6 is rotatably connected to one end of the first connecting shaft 7. The first connecting shaft 7 is vertically slidably connected to the inside of the first sliding groove 8 through a screw thread structure.

[0025] The transverse anti-tangle structure includes a second substrate 9, a first transverse limiting wheel 10, a second transverse limiting wheel 11, a second connecting shaft 12, and a second sliding groove 13. The second sliding groove 13 is disposed on the surface of the second substrate 9. The three first transverse limiting wheels 10 are equidistantly rotatably connected to the surface of the second substrate 9. The second transverse limiting wheel 11 is rotatably connected to one end of the second connecting shaft 12. The second connecting shaft 12 is vertically slidably connected to the inside of the second sliding groove 13 through a screw thread structure. The middle part of the first vertical limiting wheel 5, the second vertical limiting wheel 6, the first transverse limiting wheel 10, and the second transverse limiting wheel 11 are all provided with wire guide grooves 14.

[0026] Please see Figure 1 The welding wire is placed inside the groove 2, and then passes through the first longitudinal limiting wheel and the second longitudinal limiting wheel, as well as the first transverse limiting wheel 10 and the second transverse limiting wheel 11, and is positioned in the wire guide groove 14. The wire guide groove 14 restricts the movement trajectory of the welding wire to prevent it from deviating. During the axial movement of the welding wire, the first vertical limiting wheel 5, the second vertical limiting wheel 6, the first transverse limiting wheel 10 and the second transverse limiting wheel 11 can all rotate under the action of friction to facilitate the feeding of the welding wire.

[0027] It should be noted that the hollow vertical rod 1 can reduce the weight of the device, the groove 2 provides a directional guiding channel to limit the lateral displacement of the welding wire, and the vertical anti-wire disorder structure and the lateral anti-wire disorder structure can achieve dynamic real-time correction from two directions, while also being able to adapt to welding wires of different diameters.

[0028] The screw thread structure includes a groove 15 and a nut 16. The two grooves 15 are respectively disposed on the surface of the first substrate 4 and the second substrate 9. The two grooves 15 are respectively connected to the interior of the first slide groove 8 and the second slide groove 13. The two nuts 16 are respectively threaded to the surface of the first connecting shaft 7 and the second connecting shaft 12, and the two nuts 16 respectively abut against the surface of the first substrate 4 and the second substrate 9.

[0029] Please see Figure 2 and Figure 3 By rotating the nut 16, the nut 16 can be axially translated on the surface of the first connecting shaft 7 or the second connecting shaft 12 until the first connecting shaft 7 or the second connecting shaft 12 is locked inside the first slide groove 8 or the second slide groove 13. The first connecting shaft 7 can move inside the first slide groove 8, and the second connecting shaft 12 can move inside the second slide groove 13, thereby realizing the vertical position adjustment of the second longitudinal limiting wheel and the horizontal position adjustment of the second transverse limiting wheel 11.

[0030] The nut 16 is located inside the groove 15. The sum of the depths of the groove 15 and the first slide 8 is equal to the thickness of the first substrate 4, and the sum of the depths of the groove 15 and the second slide 13 is equal to the thickness of the second substrate 9. This method enables the nut 16 to form an embedded structure, avoiding interference from the protruding structure.

[0031] The bottom of the first substrate 4 extends vertically and is fixedly mounted on the base 3. The bottom of the second substrate 9 is fixedly mounted with a pad 17, which is fixedly mounted on the surface of the base 3. An clearance groove 18 is provided on the surface of the base 3 opposite to the second substrate 9.

[0032] Please see Figure 1 and Figure 3 The pad 17 is designed to ensure that the vertical height of the vertical anti-tangle wire structure and the horizontal anti-tangle wire structure is in a suitable position so that the welding wire remains in a straight line when passing through the horizontal anti-tangle wire structure and the vertical anti-tangle wire structure. The clearance groove 18 is designed to facilitate the operation of the nut 16 on the second connecting shaft 12.

[0033] The surface of the vertical rod 1 is provided with a vertical groove 19, and the side of the base 3 is provided with a threaded hole 20. A bolt 21 is connected inside the threaded hole 20, and a washer 22 is fitted on the surface of the bolt 21. One end of the bolt 21 passes through the vertical groove 19 and is threaded into the inside of the threaded hole 20. The washer 22 abuts against the inner wall of the vertical rod 1.

[0034] Please see Figure 1 and 4 The vertical groove 19 allows the vertical height of the base 3 to be adjusted within a certain range, and it can be fixed by bolt 21 after adjustment. The washer 22 can increase the contact area between the bolt 21 and the vertical rod 1 to prevent crushing.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
