Abstract
Description
Technical Field
[0001] This utility model belongs to the field of welding wire processing equipment, and in particular relates to a welding wire drawing and annealing device. Background Technology
[0002] Drawing and annealing are key steps in the welding wire production process. Drawing refers to the process of reducing the diameter and increasing the length of the initially processed coarse welding wire under tensile force to achieve the required dimensions. Annealing is the heat treatment process for the welding wire after processing. Annealing can eliminate residual stress inside the welding wire, restore its plasticity and toughness, and improve its microstructure, resulting in welding wire with better overall performance.
[0003] In existing technologies, traditional drawing equipment relies solely on tensile force and drawing dies to process welding wires, resulting in low drawing efficiency and a high risk of wire breakage during the drawing process, leading to unnecessary losses. Furthermore, existing welding wire drawing and annealing typically require two separate sets of equipment, occupying significant factory space and increasing equipment purchase costs for manufacturers, thus raising the overall production cost of the welding wire.

[0014] Compared with the prior art, the welding wire drawing and annealing device of this utility model has the following advantages:
[0015] (1) The welding wire drawing and annealing device of this utility model has a heat preservation cover on the operating table, and the drawing tensioning component includes two heating rods and a drawing template. Therefore, the drawing equipment and the annealing equipment can be integrated, reducing the space occupied by the equipment and saving the purchase cost of the equipment. When the device is in use, the welding wire to be treated enters the heat preservation cover through the feed port and leaves the heat preservation cover through the discharge port after passing through the drawing hole.

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0031] A wire drawing and annealing device, the structure of which can be made of Figures 1-6 The following is an illustration. In this embodiment, the welding wire drawing and annealing device includes: an operating table 1, a drawing tensioning assembly, and a heat insulation cover 2. The operating table 1 is used to provide a mounting base for other components. The drawing tensioning assembly is used to draw and heat the welding wire 7 to be treated, and to provide a suitable tensioning force for the welding wire 7 to be treated. The heat insulation cover 2 is used to reduce the rate of heat loss, so as to facilitate the annealing treatment of the welding wire 7 to be treated.
[0032] Specifically, the insulation cover 2 is adjustablely positioned on the top surface of the operating table 1. An inlet is located at one end of the insulation cover 2, and an outlet is located at the other end. An installation hole 11, communicating with the insulation cover 2, is also provided on the operating table 1. During use, the welding wire 7 to be processed enters the insulation cover 2 through the inlet and exits through the outlet.
[0033] Optionally, to improve the smoothness of the welding wire 7 entering and exiting the insulation cover 2, two rotatable feed guide wheels 212 can be provided inside the feed inlet, forming a feed gap between the two feed guide wheels 212. Correspondingly, two rotatable discharge guide wheels 222 can be provided inside the discharge outlet, forming a discharge gap between the two discharge guide wheels 222. In use, the welding wire 7 will enter and exit the insulation cover 2 through the feed gap and the discharge gap. The rotation of the feed guide wheels 212 and the discharge guide wheels 222 can reduce the resistance of the welding wire 7, so that the welding wire 7 can smoothly enter and exit the insulation cover 2.
[0034] like Figure 2 and Figure 4As shown, in this embodiment, the drawing tensioning assembly is disposed inside the heat insulation cover 2, and the drawing tensioning assembly includes a support plate 3 and a drawing template 5. A connecting shaft 31 is provided on the bottom surface of the support plate 3, and the connecting shaft 31 is rotatably disposed inside the mounting hole 11. Two heating rods 4 perpendicular to the support plate 3 are provided on the top surface of the support plate 3, the two heating rods 4 being located on opposite sides of the connecting shaft 31, and a rotatable heat-conducting roller sleeve 41 is fitted onto each heating rod 4. The drawing template 5 is detachably disposed on the top surface of the support plate 3, the drawing template 5 being located between the two heating rods 4, and a drawing hole 51 for accommodating the welding wire 7 to be processed is provided on the drawing template 5.
[0035] like Figure 3 As shown, during use, the welding wire 7 to be treated enters the heat insulation cover 2 through the feed inlet and exits the heat insulation cover 2 through the discharge outlet after passing through the drawing hole 51. The two heating rods 4 should be located on either side of the welding wire 7. When the heating rods 4 are activated, the welding wire 7 will be heated, thus reducing the difficulty of drawing the wire 7 through the drawing hole 51 and improving the drawing efficiency. Secondly, the operator can drive the drawing tensioning assembly to rotate according to actual needs (to... Figure 3 Taking the illustrated state as an example, when the pulling tensioning assembly is driven to rotate clockwise, the tension force inside the welding wire 7 to be treated can be increased; when the pulling tensioning assembly is driven to rotate counterclockwise, the tension force inside the welding wire 7 to be treated can be decreased. This ensures that the welding wire 7 to be treated receives sufficient tension, guaranteeing a good pulling effect. Furthermore, since the heat insulation cover 2 reduces the rate of heat loss, it creates a high-temperature environment. This allows the welding wire 7 to undergo annealing after the pulling process, resulting in good overall performance.
[0036] It should be noted that the heating rod 4 described in this embodiment is a common electric heating rod. In order to facilitate the supply of power to the heating rod 4, a wire 8 that is electrically connected to the heating rod 4 should be provided at the bottom end of the connecting shaft 31 so as to facilitate the connection between the power supply and the heating rod 4 through the wire 8.
[0037] Optionally, to improve the stability of the welding wire 7 when it passes through the drawing and tensioning assembly, the side wall of the heat-conducting roller sleeve 41 may be provided with a receiving annular groove 411 for accommodating the welding wire 7, so as to prevent the welding wire 7 from moving along the axial direction of the heat-conducting roller sleeve 41.
[0038] As an optional implementation of this embodiment, to facilitate the operator in passing the welding wire 7 to be treated through the device in the manner described above, the top of the heat insulation cover 2 may be provided with an operating port 24, and a removable cover 241 may be provided on the operating port 24. During use, the operator should first remove the drawing template 5, then pass one end of the welding wire 7 to be treated through the drawing hole 51, and then install the drawing template 5 onto the support plate 3, with the two heating rods 4 positioned on either side of the welding wire 7 to be treated. Correspondingly, the device should have a feed cut 211 at the top of the feed inlet communicating with the operating port 24, and a discharge cut 221 at the top of the discharge outlet communicating with the operating port 24, so that the welding wire 7 to be treated can enter the feed gap and discharge gap after being assembled with the drawing tensioning assembly.
[0039] Optionally, to achieve a detachable connection between the drawing template 5 and the bearing plate 3, such as... Figure 4 As shown, the support plate 3 may be provided with a insertion groove 32. During assembly, the worker can insert the bottom end of the drawing template 5 into the insertion groove 32. In addition, to prevent the drawing template 5 from separating from the support plate 3, the drawing template 5 may also be provided with a connecting ear 52, which has a connecting screw hole. An assembly bolt 521 is provided inside the connecting screw hole, and an assembly screw hole 33 for accommodating the assembly bolt 521 is provided on the periphery of the insertion groove 32, thereby improving the installation reliability of the drawing template 5 with the help of the assembly bolt 33.
[0040] It should be noted that in actual use, the staff should select the inner diameter of the pull hole 51 according to the actual pull requirements of the welding wire 7 to be processed, and install the pull template 5 with the pull hole 51 of appropriate inner diameter on the bearing plate 3.
[0041] like Figure 5 and Figure 6 As shown, to prevent abnormal rotation of the tensioning assembly during normal operation, this embodiment provides a detachable locking ring 6 at the bottom end of the connecting shaft 31, thereby limiting the rotation of the tensioning assembly. Specifically, the locking ring 6 has a first locking screw hole 61, and a locking bolt 62 is provided inside the first locking screw hole 61. The bottom surface of the operating table 1 has multiple second locking screw holes 14 for accommodating the locking bolts 62, and the multiple second locking screw holes 14 should be arranged in a ring around the periphery of the mounting hole 11. After the operator rotates the tensioning assembly to obtain a suitable tension force inside the welding wire 7 to be treated, the locking bolt 62 can be screwed into the second locking screw hole 14 at the current position, thereby preventing abnormal rotation of the tensioning assembly.
[0042] As another optional implementation of this embodiment, since the annealing treatment time varies for different types of welding wires 7, the position of the heat insulation cover 2 can be adjusted to accommodate different annealing treatment times, thereby adjusting the dwell time of the welding wire 7 inside the heat insulation cover 2.
[0043] like Figure 2 As shown, the operating table 1 may be equipped with a positioning screw 13, and the insulation cover 2 is equipped with a positioning plate 25, and the positioning plate 25 is equipped with a positioning elongated hole 251 for accommodating the positioning screw 13. Figure 3 For example, when the welding wire 7 to be processed needs to stay inside the insulation cover 2 for a longer period of time, the insulation cover 2 can be driven to slide to the right. When the welding wire 7 to be processed needs to stay inside the insulation cover 2 for a shorter period of time, the insulation cover 2 can be driven to slide to the left, thereby meeting different practical needs.
[0044] Optionally, to facilitate fixing the position of the insulation cover 2, a positioning nut 131 may also be provided on the positioning screw 13, and the positioning nut 131 should be located above the positioning plate 25. After the insulation cover 2 is moved to a suitable position, the operator can tighten the positioning nut 131 to prevent the insulation cover 2 from sliding abnormally.
[0045] In addition, in this embodiment, a guide strip 12 may be provided on the top surface of the operating table 1, and a guide groove 23 for accommodating the guide strip 12 may be provided on the bottom surface of the heat insulation cover 2, so as to guide the sliding of the heat insulation cover 2 by means of the cooperation of the guide strip 12 and the guide groove 23.
[0046] The effects of the above solution are explained below:
[0047] This embodiment provides a wire drawing and annealing apparatus that integrates drawing and annealing equipment, reducing space requirements and saving on equipment purchase costs. During the drawing process, the heating rod increases the temperature of the welding wire, thus improving drawing efficiency. Furthermore, the apparatus allows adjustment of the tension of the welding wire by rotating the drawing tensioning assembly, ensuring optimal drawing results. Additionally, the apparatus can control the residence time of the welding wire inside the insulation cover by adjusting its position to meet different annealing requirements.
[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
