Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of welding wire processing, in particular to a welding wire drawing lubricating powder coating box and a welding wire drawing device. Background Art
[0002] Welding wire is a metal wire welding material used as filler metal or as a conductive material. In gas welding and tungsten arc welding, welding wire is used as filler metal; in submerged arc welding, electroslag welding and other metal arc welding, welding wire is both filler metal and conductive electrode. The surface of welding wire is not coated with anti-oxidation flux.
[0003] The processing of welding wire includes pretreatment and copper plating. Pretreatment refers to shelling, grinding, diameter reduction drawing, alkali washing and pickling of the welding wire. Shelling is to bend the raw material with multiple rollers to separate the surface oxide layer of the raw material, and further remove the surface oxide layer by grinding, and then reduce the diameter by drawing to make the coarser raw material gradually thinner, and then remove the residual oil on the surface by alkali washing and pickling.
[0004] Generally, welding wire is drawn by cold drawing. The welding wire passes through a die with a smaller diameter. Under the action of traction, it passes through the die to achieve the purpose of reducing the diameter. In order to ensure the smooth drawing, a layer of lubricant needs to be attached to the raw material during the drawing process. Generally, lubricants are divided into two categories: liquid and powder. When lubricating powder is used, lubricating powder is added to the material box, and then the welding wire passes through the powder and then through the die for drawing.
[0005] Generally, in order to ensure the full use of lubricating powder, the hole through which the welding wire passes needs to be opened at a lower position in the material box, because adhesion can only be formed when the welding wire is completely buried in the lubricating powder. If part of the welding wire is located on the upper part of the lubricating powder, this part will not contact the lubricating powder, which will lead to poor lubrication effect. However, the lower opening position will cause an angle bend in the welding wire's travel path, which will increase the resistance to travel. At the same time, under the normal condition that no external force is applied, the adhesion effect of the lubricating powder and the welding wire is limited. Therefore, extrusion is used to apply a certain pressure, which can improve the adhesion effect. However, excessive pressure can easily cause the lubricating powder to coke and denature, which will make the lubrication effect worse. Utility Model Content

DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. The described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] In the relevant prior art, in order to ensure the full use of lubricating powder, the hole through which the welding wire passes needs to be opened at a lower position in the material box, because adhesion can only be formed when the welding wire is completely buried in the lubricating powder. If part of the welding wire is located on the upper part of the lubricating powder, this part will not contact the lubricating powder, which will lead to poor lubrication effect. However, the lower opening position will cause an angle bend in the welding wire's travel path, which will increase the resistance to travel. At the same time, when no external force is applied, the adhesion effect of the lubricating powder and the welding wire is limited. Therefore, extrusion is used to apply a certain pressure, which can improve the adhesion effect. However, excessive pressure can easily cause the lubricating powder to coke and denature, which will in turn worsen the lubrication effect.
[0026] In order to solve the problems existing in the related prior art, the utility model proposes a welding wire drawing lubricating powder coating box and a welding wire drawing device. The principle and structure of the utility model are described in detail below in conjunction with the drawings and embodiments. Example
[0027] See also Figures 1 to 3 The utility model proposes a welding wire drawing lubricating powder coating box, comprising a box body 1, a first partition plate 2 and a second partition plate 3. The first partition plate 2 and the second partition plate 3 are vertically fixed in the box body 1 and divide the box body 1 into a first chamber, a second chamber and a third chamber. The box body 1 is provided with through holes for the welding wire to pass through on both sides along the length direction and the first partition plate 2 and the second partition plate 3. When in use, the welding wire passes through the first chamber, the second chamber and the third chamber in sequence. The first chamber is used to store lubricating powder, a rotating device 4 is provided in the second chamber, and a die head 5 is fixed in the third chamber. The rotating device 4 comprises a bearing 401, a rotating ring 402 and a first motor 403. The rotating ring 402 is annular, and a plurality of material grooves 404 are provided inside the rotating ring 402. The outer wall of the rotating ring 402 is provided with a groove, which is matched and fixed with the bearing 401. The first motor 403 drives the rotating ring 402 to rotate, and the transmission mode is a worm gear transmission.
[0028] When in use, lubricating powder is added to the first chamber to ensure that when the welding wire passes through the first chamber, the height of the upper accumulation of the lubricating powder is higher than the horizontal height when the welding wire passes through. Then the welding wire passes through the middle of the rotating ring 402 and finally comes out from the die head. As the welding wire passes, lubricating powder will adhere to the welding wire. The lubricating powder can provide lubrication for the welding wire passing through the die head to ensure smooth drawing. At the same time, a lubricating film layer will also be formed on the surface of the welding wire. In this way, the lubricating powder will be continuously consumed. When a certain amount of lubricating powder is consumed, the welding wire passing through the first chamber cannot ensure that the surface of the welding wire is completely attached to the lubricating powder. The traditional operation is to add lubricating powder in time to ensure the lubrication effect. In this solution, the rotating ring 402 can be driven to rotate by the first motor 403 through the worm gear. As the rotating ring 402 rotates, the material trough 404 can drive the lower lubricating powder to rotate to the upper part of the welding wire, and then scatter on the welding wire, so as to ensure the adhesion effect.
[0029] Please continue reading Figure 2 A connecting portion 405 is further provided on the side of the rotating ring 402 close to the second partition plate 3. The internal cross-section of the connecting portion 405 is trapezoidal. The opening size at the end close to the rotating ring 402 is the same as the inner diameter of the rotating ring 402, and the opening size at the end close to the die head 5 is smaller than the opening size at the feeding end of the die head 5. In this way, a temporary storage space can be formed at the connecting portion and the feeding end of the die head. The lubricating powder attached to the surface of the welding wire will enter this temporary storage space and accumulate more and more, which can form a certain pressure. Under a certain pressure, the adhesion effect can be improved.
[0030] At the same time, a plurality of extrusion holes 6 are provided at equal angles on one side of the die head 5 close to the feed port, and the bearing is a cylindrical roller bearing. In this way, when too much lubricating powder is deposited, the excess lubricating powder will be discharged from the middle of the extrusion hole 6 and fall into the third chamber, which can prevent the lubricating powder from coking due to excessive pressure. At the same time, the lubricating powder in the third chamber can also be recycled and reused.
[0031] Furthermore, the bottom of the first chamber is inclined, and the height of the bottom of the first chamber gradually decreases along the advancing direction of the welding wire. The height of the first chamber near one end of the rotating ring 402 is the same as the height of the lowest point of the inner diameter of the rotating ring 402. In this way, the lubricating powder will be concentrated near the rotating ring 402, thereby ensuring the adhesion effect of the lubricating powder. Example
[0032] Based on the same inventive concept, the utility model also proposes a welding wire drawing device, including a machine table 7 and a drawing unit 8, the drawing unit 8 includes a guide wheel 801, a limiting wheel group 802, a traction disc 803, a second motor 804 and the above-mentioned material box, the welding wire passes through the guide wheel 801, the limiting wheel group 802, the material box and the traction disc 803 in sequence, and the second motor 804 drives the traction disc 803 to rotate to provide traction.
[0033] It also includes a machine platform 7 and a machine cover 806 , and a plurality of drawing units 8 are fixed on the machine platform 7 , and each machine cover 806 corresponds to a drawing unit 8 .
[0034] A cleaning tank 9 is also provided at one end of the machine 7 for discharging materials. A heating wire 10 is arranged in the cleaning tank 9. A liquid inlet and a liquid outlet are arranged at the lower part of the cleaning tank 9. A plurality of brush heads 11 are arranged at the bottom of the cleaning tank 9. A third motor 12 is arranged at the lower part of the cleaning tank 9. The third motor 12 drives the brush head 11 to rotate.
[0035] The specific working principle is as follows:
[0036] After the welding wire is peeled and polished, it is then wrapped around the guide wheel 801 and then passed into the material box through the limiting wheel group 802. The guide wheel group consists of two groups, one group is placed vertically and the other group is placed horizontally, which plays a guiding role to prevent the welding wire from bending and causing it to break. After entering the material box, it is lubricated with lubricating powder and then drawn through the die head 5 for diameter reduction. When multiple drawing units 8 are set on the machine 7, the diameter of the die head 5 on each drawing unit 8 gradually becomes smaller, so that the drawing is performed in stages, and the wire will not be broken due to the large difference in diameter before and after drawing.
[0037] A lubricating layer will be formed on the surface of the welding wire after drawing, and the main thing to do during the alkaline washing and pickling process is to remove impurities on the surface of the welding wire. At this time, the drawn welding wire can be passed through the cleaning tank 9, and cleaning liquid is added to the cleaning tank 9 for pre-cleaning. Liquid is added at one end and discharged at the other end to ensure that the flow direction of the cleaning liquid is opposite to the forward direction of the welding wire for sufficient cleaning. At the same time, an electric heater 10 is provided at the bottom of the cleaning tank to heat the cleaning liquid to improve the cleaning effect. At the same time, a third motor 12 fixed at the bottom drives the brush head 11 in the cleaning tank to brush the welding wire to further improve the cleaning effect.
[0038] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
