Description

Technical Field

[0001] The present invention relates to the field of welding wire processing, and in particular to welding wire processing equipment and a processing method. Background Art

[0002] Solid welding wire is a commonly used welding material. It has the advantages of high strength, good formability, and corrosion resistance. It is widely used in the fields of automobiles, aviation, shipbuilding, and construction. For the production of solid welding wire, the cold drawing process is generally used. Because the diameter of the solid welding wire is small, the cold drawing process can better control the dimensional accuracy and obtain better surface quality, while also ensuring the mechanical properties of the material. Cold drawing refers to the process of deforming metal materials into different shapes through a stretching process. Its characteristic is that it is carried out at room temperature and does not require heating, so it has little effect on the mechanical properties of the material.

[0003] The cold drawing process of solid welding wire mainly includes the following steps: cutting raw materials, pickling, grinding, and wire drawing. In this process, the solid welding wire will undergo multiple drawing until it reaches the required shape and size.

[0004] Among them, grinding is a crucial link, which will affect the dimensional accuracy, surface finish and mechanical properties of the welding wire. The existing grinding is done by a grinder or manual polishing, and the grinding effect is not good. Some oxide scale, oil stains, etc. will remain on the surface, affecting the yield.

[0047] The following will refer to the attached Figures 1 to 8 The present invention will be described in detail with reference to the embodiments. Figure 2 The direction indicated by x is the front side of the present invention.

[0048] Embodiment 1

[0049] In general, the present invention relates to a welding wire processing device for cold drawing welding wire. It comprises a bottom plate 1, a material discharge assembly and a material receiving assembly arranged on the bottom plate 1, a processing chamber 3 arranged on the bottom plate 1 between the material discharge assembly and the material receiving assembly, a placement plate 6 arranged on the bottom plate 1 between the processing chamber 3 and the material receiving assembly, a cold drawing assembly arranged on the bottom plate 1 between the material receiving assembly and the processing chamber 3, and a feed hole 301 and a discharge hole 302 for feeding welding wire in and out at the front and rear sides of the processing chamber 3, respectively, and a spray assembly is arranged on the processing chamber 3, and the spray assembly is located above the welding wire. A de-impurity assembly is also arranged on the placement plate 6.

[0050] In this embodiment, after the welding wire to be processed extends out from the discharge component, it will enter the processing chamber 3 and be pickled by spraying the pickling solution by the spray component to remove the surface oxide scale and stains. Then it will enter the impurity removal component on the placement plate 6 to grind the surface of the welding wire to remove its surface impurities. Then it will enter the cold drawing component to cold draw the welding wire, and finally the processed welding wire will be collected by the collecting component.

[0051] Before the welding wire is cold drawn, it is fully polished by the impurity removal component, which can further improve the surface quality of the welding wire. By removing the burrs and uneven parts on the surface of the welding wire, the welding wire is smoother, reducing the resistance during welding, and improving the quality of the welded joint. The polished welding wire is not only more beautiful visually, but also provides better wettability and fluidity during welding, which helps to form a more uniform weld, thereby improving the strength and corrosion resistance of the welded joint.

[0052] Among them, Figures 4 to 6As shown, the impurity removal component includes a mounting ring 7 rotatably arranged on the placement plate 6, an inner ring 701 fixedly arranged in the mounting ring 7, a telescopic rod 704 uniformly slidably arranged on the inner ring 701 around the center of the inner ring 701, a grinding wheel 706 fixedly arranged at the end of the telescopic rod 704, and a second spring 705 sleeved on the telescopic rod 704; in addition, an adjusting ring 702 is threadedly connected to the inner side wall of the mounting ring 7, and an extrusion portion 703 abutting against the top inclined surface of the telescopic rod 704 is fixedly provided on the inner side wall of the adjusting ring 702; a first motor 708 is provided on one side of the placement plate 6, and the first motor 708 and the adjusting ring 702 are connected by a belt 707.

[0053] like Figure 2 As shown, during the specific implementation, the welding wire passes through the center of the mounting ring 7 and the inner ring 701, and then each telescopic rod 704 is driven to extend toward the center of the mounting ring 7, so that the grinding wheel 706 at its end abuts against the outer wall of the welding wire, and the first motor 708 drives the mounting ring 7 to rotate on the placement plate 6 through the belt 707.

[0054] It should be noted that in order to adapt to welding wires of different thicknesses and to ensure that the telescopic rod 704 does not shake after adjustment, in this embodiment, by rotating the adjusting ring 702, the extrusion portion 703 can squeeze the inclined end of the telescopic rod 704 to extend the extrusion rod. Since the adjusting ring 702 is threadedly connected to the mounting ring 7, the thread has a self-locking function after adjustment, which can limit the telescopic rod 704.

[0055] In addition, the second spring 705 can reset the telescopic rod 704 after being extended. During installation, one end of the second spring 705 is fixedly connected to the side wall of the telescopic rod 704 , and the other end is fixedly connected to the inner ring 701 .

[0056] like Figures 1 to 3 As shown, the spray assembly is used to spray liquid to pickle the welding wire to remove surface impurities and make subsequent grinding more thorough. It includes a storage container 5 fixedly arranged on the top of the processing chamber 3, a long tube 501 connected to the storage container 5, and a plurality of nozzles 502 connected to the long tube 501 and extending into the processing chamber 3. The liquid is pumped into the long tube 501 by a water pump provided in the storage container 5, and sprayed out by the nozzle 502, and falls on the welding wire in the processing chamber 3.

[0057] In order to increase the pickling effect of the welding wire in the processing chamber 3, in this embodiment, as shown in FIG. Figure 2 and Figure 3As shown, a stretching assembly is also provided in the processing chamber 3, and the stretching assembly includes a first crossbar 401 and a second crossbar 402 which are symmetrically arranged and transversely arranged in the processing chamber 3 and whose ends are fixedly connected to the inner wall of the processing chamber 3, and a first wheel 4011, a second wheel 4012 and a third wheel 4013 are respectively and rotatably arranged at intervals on the first crossbar 401, and a fourth wheel 4021, a fifth wheel 4022 and a sixth wheel 4023 corresponding thereto are respectively and rotatably arranged at intervals on the second crossbar 402;

[0058] In specific implementation, the welding wire enters the processing chamber 3 from the feeding hole 301, is wound from the first wheel 4011 to the third wheel 4013, is wound from the third wheel 4013 to the second wheel 4012, is wound from the second wheel 4012 to the fifth wheel 4022, is wound from the fifth wheel 4022 to the third wheel 4013, is wound from the third wheel 4013 to the sixth wheel 4023, and extends from the sixth wheel 4023 to the discharge hole 302 and out of the processing chamber 3. In this way, the processing length of the welding wire in the processing chamber 3 is increased, thereby increasing the pickling effect.

[0059] It should be understood that the unprocessed welding wire surface may produce pollutants such as oxides, rust, and oil, which will affect the performance and appearance of the metal. Pickling can effectively remove these pollutants by using acidic solutions (such as hydrochloric acid, sulfuric acid, phosphoric acid, etc.), restoring the metal surface to a more original state. In addition, pickling can also remove the oxide layer and other impurities on the metal surface, increase the roughness of the metal surface, and facilitate subsequent grinding and removal of impurities.

[0060] like Figure 7 As shown, the above-mentioned cold drawing assembly includes a support plate 8, a mold 804 rotatably arranged inside the support plate 8, a second gear 803 fixedly mounted on the outer wall of the mold 804, a second motor 801 fixedly arranged on the top surface of the support plate 8, and a first gear 802 fixedly arranged on the output shaft of the second motor 801, and the first gear 802 and the second gear 803 are meshed.

[0061] During specific implementation, the welding wire is inserted into the mold 804, and the inner diameter of the mold 804 is smaller than the welding wire. After stretching and the second motor 801 driving the mold 804 to rotate, the diameter of the welding wire can be reduced. The rotation of the mold 804 can also ensure the smoothness of the welding wire surface after drawing.

[0062] As a preferred embodiment, the end of the die 804 away from the receiving assembly is funnel-shaped, and the inner diameter gradually decreases as it approaches the receiving assembly, and the welding wire passes through the die 804. Such a design can facilitate the operator to insert the welding wire into the die 804.

[0063] In addition, the above-mentioned discharge assembly includes a discharge frame 201 fixedly connected to the top surface of the base plate 1, a discharge roller 205 rotatably arranged in the discharge frame 201, an extrusion column 202 slidably arranged on the top of the discharge frame 201, a first spring 203 mounted on the extrusion column 202, and a pressure plate 204 fixedly arranged at the bottom end of the extrusion column 202 and located directly above the discharge roller 205.

[0064] In specific implementation, the welding wire to be processed is wound on the unwinding roller 205, and the first spring 203 is compressed to drive the pressing plate 204 to press the welding wire on the unwinding roller 205 to prevent the welding wire processing tension from being too large, causing the winding roller 901 to rotate. One end of the first spring 203 is fixedly connected to the top surface of the unwinding frame 2, and the other end is fixedly connected to the top surface of the pressing plate 204.

[0065] The above-mentioned material receiving assembly includes a material receiving frame 9 fixedly connected to the top surface of the bottom plate 1, a material receiving roller 901 rotatably arranged in the material receiving frame 9, and a third motor 902 fixedly arranged at the bottom end of the side wall of the material receiving frame 9 and fixedly connected to the material receiving roller 901.

[0066] The processed welding wire will be wound on the receiving roller 901, and the third motor 902 provides the pulling force for the entire wire drawing process.

[0067] Embodiment 2

[0068] This embodiment provides a welding wire processing method. This method is used for the welding wire processing equipment provided in the above embodiment 1. Fig. 9 As shown, the processing method comprises the following steps:

[0069] S1, the welding wire to be processed is pulled out from the discharge assembly, and sequentially enters the processing chamber, the impurity removal assembly, the cold drawing assembly, and finally wound into the receiving assembly;

[0070] S2, rotating the adjusting ring so that the extrusion part squeezes the telescopic rod, driving the side wall of the grinding wheel to fit tightly with the welding wire;

[0071] S3, start the spraying component to spray the electrolytic pickling solution, start the impurity removal component to remove impurities on the surface of the welding wire, and start the cold drawing component to draw;

[0072] S4, start the material collecting component to collect the processed welding wire.

[0073] The dimensional accuracy, surface finish and mechanical properties of the welding wire are improved by fine grinding of the impurity removal components, thereby improving the welding processability and welding quality.

[0074] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
