Description

Technical Field

[0001] The invention belongs to the technical field of stainless steel welding wire surface treatment, in particular to a stainless steel welding wire surface treatment device. Background Art

[0002] Stainless steel welding wire is used as filler metal or as a conductive metal wire welding material. In gas welding and tungsten inert gas shielded arc welding, the welding wire is used as filler metal. In submerged arc welding, electroslag welding and other metallurgical gas shielded arc welding, the welding wire is both filler metal and conductive electrode. Before use, a layer of oxide layer will appear on the surface of the stainless steel welding wire due to long-term storage. Therefore, the oxide layer on its surface needs to be treated to better weld.

[0003] A patent application with publication number CN114986279B discloses a surface treatment process for stainless steel welding wire. An elastic plate is attached to the outside of the welding wire and deforms and bends. The grinding belt changes with the change of the elastic plate, so that it can adaptively fit according to welding wires of different thicknesses, improve applicability, and at the same time improve the grinding treatment effect.

[0004] In the above-mentioned prior art, when grinding stainless steel welding wire, a disc grinding wheel is generally used for grinding. Since the outer side of the welding wire is an arc surface, the disc grinding wheel cannot fit tightly to the stainless steel welding wire, and the disc grinding wheel needs to be continuously moved to rotate around the stainless steel welding wire for grinding. Using the butterfly grinding wheel to grind around the stainless steel welding wire while pulling the stainless steel welding wire will cause the stainless steel welding wire to shake. The shaking of the stainless steel welding wire will cause uneven force on the disc grinding wheel, resulting in the surface roughness of the stainless steel welding wire not meeting the standard, and even local scratches and unevenness. Scratches on the surface of the stainless steel welding wire will cause the surface protective layer to be damaged, and the exposed metal part is easily oxidized and corroded, which will shorten the service life if used for a long time.

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] Example 1: Figure 1-Figure 5 As shown, a stainless steel welding wire surface treatment device described in an embodiment of the present invention includes a cylinder 1, a first grinding assembly is arranged inside the cylinder 1, the first grinding assembly includes grinding paper 11 arranged inside the cylinder 1, the grinding paper 11 is wrapped around the outside of the stainless steel welding wire, T-shaped blocks 12 are respectively provided on both sides of the grinding paper 11, and cylindrical wheels 111 are rotatably arranged on both sides between the two T-shaped blocks 12. The rolled grinding paper 11 is installed on the outside of the cylindrical wheel 111 on one side, and the end of the rolled grinding paper 11 is installed on the outside of the cylindrical wheel 111 on the other side. A special-shaped through hole 112 is provided in the middle of the cylindrical wheel 111, and special-shaped rods 2 are respectively slidably provided at the positions corresponding to the two cylindrical wheels 111 in the middle of the cylinder 1. The special-shaped rods 2 are located on the side of the first grinding assembly away from the second grinding assembly, and the special-shaped rods 2 are respectively slidably arranged in the special-shaped through holes 112. A plurality of second grinding assemblies are rotatably provided on one side of the first grinding assembly, and the structure of the second grinding assembly is consistent with that of the first grinding assembly.

[0032] The grinding wheel is not easy to be used for grinding, and the grinding wheel is not easy to be used for grinding. The steel welding wire slides between each grinding paper 11, and each grinding paper 11 is evenly distributed around the stainless steel. At the same time, each grinding paper 11 pulls the stainless steel welding wire with the same force to prevent shaking when pulling the stainless steel welding wire. After a period of use, the grinding paper 11 needs to be replaced regularly. By driving each second grinding assembly to rotate to a side parallel to the first grinding assembly, and then driving the special-shaped rod 2 to slide into the special-shaped through hole 112 set inside each cylindrical wheel 111, and then driving the special-shaped rod 2 on one side to rotate, driving the cylindrical wheel 111 on one side to rotate, the used grinding paper 11 can be wrapped around the outside of the cylindrical wheel 111, thereby pulling out the new grinding paper 11 on the other side, thereby replacing the grinding paper 11, solving the problem that the shaking of the stainless steel welding wire will cause uneven force on the surface of the stainless steel welding wire during grinding, which may cause local scratches or unevenness on the surface of the stainless steel welding wire, and can evenly grind the surface of the stainless steel welding wire, and can replace multiple grinding papers 11 at the same time.

[0033] like Figure 1 As shown, the lower end of the cylinder 1 is fixedly connected to the bottom plate 4 through the second support block 16, and a gear ring 14 is rotatably provided in the middle of the cylinder 1 corresponding to the position of each second grinding assembly, and the second grinding assemblies are fixedly connected to the inner side of the gear ring 14 respectively.

[0034] Specifically, by driving each gear ring 14 to rotate, the gear ring 14 drives the second grinding assembly to rotate in the cylinder 1, so that each second grinding assembly rotates to a side parallel to the first grinding assembly, and then drives the special-shaped rod 2 to slide into the special-shaped through hole 112 set inside each cylindrical wheel 111 to replace the grinding paper 11.

[0035] like Figure 1As shown, one side of the gear ring 14 is meshed with a gear 141 , one side of the gear 141 is fixedly connected to the output end of the first motor 142 , and the first motor 142 is fixedly connected to the base plate 4 through a motor base.

[0036] Specifically, by starting the first motor 142 to drive the gear 141 to rotate, the gear 141 drives the corresponding ring gears 14 to rotate inside the cylinder 1, and the ring gears 14 can drive the second grinding assemblies to rotate.

[0037] like Figure 5 As shown, the cylindrical wheels 111 rotate and pass through the middle of the T-shaped block 12 respectively. The first grinding assembly also includes a first rectangular plate 13 fixed to one side of the two T-shaped blocks 12. A first rectangular block 131 is provided on the side of the first rectangular plate 13 away from the T-shaped block 12. The first rectangular plate 13 is fixed to the first rectangular block 131 through a telescopic rod 132. A second spring 133 is provided on the outside of the telescopic rod 132. The first rectangular block 131 is fixed to the inside of the cylinder 1.

[0038] Specifically, each grinding paper 11 is wrapped around the outside of the stainless steel welding wire, and the second spring 133 set on one side of the first rectangular block 131 contracts to drive the telescopic rod 132 to contract. The telescopic rod 132 drives the grinding paper 11 set in the middle of the T-shaped block 12 through the first rectangular plate 13 to be pulled toward the side away from the stainless steel welding wire, so that the grinding paper 11 is tightly wrapped around one side of the stainless steel welding wire. Each grinding paper 11 is evenly distributed around the stainless steel welding wire, pulling the stainless steel welding wire to keep it in a stationary state.

[0039] like Figure 6 As shown, a second rectangular block 25 is commonly provided on the outer side of one end of the two special-shaped rods 2 away from the first grinding assembly. The special-shaped rods 2 are rotatably arranged in the middle of the second rectangular block 25 through a ring 251. A sliding assembly is provided on the upper end of the second rectangular block 25. The sliding assembly includes a slide 253 provided on the upper end of the second rectangular block 25. An electric slide rail 254 is fixed to the position corresponding to the slide 253 inside the cylinder 1, and the slide 253 is slidably arranged on one side of the electric slide rail 254.

[0040] Specifically, by driving the slide 253 to slide on one side of the electric slide rail 254, the slide 253 drives the special-shaped rod 2 to be inserted into the special-shaped through hole 112 through the second rectangular block 25, and then drives the ring 251 to rotate in the middle of the second rectangular block 25 to drive the special-shaped rod 2 to rotate, thereby replacing the polishing paper 11.

[0041] like Figure 6 As shown, a conical block 24 is fixedly connected to one end of the special-shaped rod 2 away from the second rectangular block 25 .

[0042] Specifically, when the special-shaped rod 2 is driven to be inserted into the special-shaped through hole 112, the tip of the conical block 24 provided at the end of the special-shaped rod 2 is first inserted into the special-shaped through hole 112, so that the special-shaped rod 2 can be smoothly inserted into the special-shaped through hole 112 to prevent jamming.

[0043] like Figure 7 As shown, a fixing assembly is respectively provided on the side of the second grinding assembly away from the first grinding assembly, and the fixing assembly includes a plurality of circular holes 113 opened on the edge of one end of the cylindrical wheel 111, and a first slide rail 121 is respectively fixedly connected to the position corresponding to the circular holes 113 on one side of the T-shaped block 12, and a cylindrical bar 114 is respectively slidably provided in the circular hole 113, and the cylindrical bar 114 can slide in the middle of the first slide rail 121 through the waist-shaped block 115, and the waist-shaped block 115 is fixed to one side of the inside of the first slide rail 121 through the first spring 122.

[0044] Specifically, when the special-shaped rod 2 is driven to be inserted into the special-shaped through hole 112 provided in the middle of the cylindrical wheel 111 in the second grinding assembly, the special-shaped rod 2 slides to the end of the cylindrical wheel 111 and presses against the waist-shaped block 115 to slide to one side. The waist-shaped block 115 moves to drive the cylindrical bar 114 to slide in the circular hole 113. The waist-shaped block 115 slides in the middle of the first slide rail 121 and squeezes the first spring 122. At this time, the first spring 122 is in a compressed state until the cylindrical bar 114 completely slides to the outside of the circular hole 113. At this time, the special-shaped rod 2 It can drive the cylindrical wheel 111 to rotate. When the special-shaped rod 2 drives the cylindrical wheel 111 to rotate to replace the sanding paper 11, the special-shaped rod 2 slides toward the outside of the special-shaped through hole 112. At this time, the first spring 122 releases its elastic force, pushing the waist-shaped block 115 to move and drive the cylindrical bar 114 to slide toward the inside of the circular hole 113 until the cylindrical bar 114 completely slides into the circular hole 113. Until the cylindrical bar 114 completely slides into the circular hole 113, the cylindrical wheel 111 and the T-shaped block 12 are in a fixed state to prevent the sanding paper 11 from rotating.

[0045] like Figure 6 As shown, the upper end of the special-shaped rod 2 is respectively provided with a second cylindrical rod 22, and the second cylindrical rod 22 is respectively provided at the upper end of the first rectangular plate 13, and the second cylindrical rod 22 is fixed to the middle of the second rectangular block 25. The special-shaped rod 2 is slidingly provided with a first cylindrical rod 21 on the outside of one end of the second rectangular block 25, and the second cylindrical rod 22 is slidingly provided with a third cylindrical rod 23 on the outside of one end of the second rectangular block 25. The first cylindrical rod 21 is rotated away from the outside of one end of the special-shaped rod 2 to be provided with a third rectangular block 3, and the third cylindrical rod 23 is fixed to the middle of the third rectangular block 3. A rectangular frame 15 is fixed to one side of the cylinder 1, and the rectangular frame 15 is fixed to the upper end of the bottom plate 4 through a first support block 151. The upper end of the third rectangular block 3 is fixed to the output end of the hydraulic rod 31, and the hydraulic rod 31 is fixed to the upper end of the rectangular frame 15 through a U-shaped support block 32.

[0046] Specifically, when the stainless steel welding wire is in the middle of each grinding paper 11, when the grinding paper 11 is replaced, each grinding paper 11 needs to be rotated to the same direction, which will pull the stainless steel welding wire in one direction, thereby causing the stainless steel welding wire to deform. By driving the second rectangular block 25 to drive the special-shaped rod 2 and the second cylindrical rod 22 to slide toward the side close to the first grinding component, the special-shaped rod 2 is driven to slide out from the inside of the first cylindrical rod 21 to the outside, and at the same time, the second cylindrical rod 22 is driven to slide out from the inside of the third cylindrical rod 23 to the outside, until the special-shaped rod 2 is inserted into the special-shaped through hole 112 At the same time, the second cylindrical rod 22 is located at the upper end of the first rectangular plate 13, and then the hydraulic rod 31 is driven to extend, driving the third rectangular block 3 to slide downward. The third rectangular block 3 drives the special-shaped rod 2 and the second cylindrical rod 22 to slide downward through the third cylindrical rod 23 and the first cylindrical rod 21 respectively. The second cylindrical rod 22 drives the grinding paper 11 to move downward through the first rectangular plate 13 and stretches the second spring 133 so that the grinding paper 11 is not tightly attached to the side of the stainless steel welding wire at this time. Then, the special-shaped rod 2 is driven to rotate to replace the grinding paper 11 to prevent the stainless steel welding wire from deformation.

[0047] like Figure 6 As shown, a rectangular bar 252 is slidably provided inside the upper end of the second rectangular block 25 , and the slide 253 is fixedly connected to the rectangular bar 252 .

[0048] Specifically, when the third rectangular block 3 drives the special-shaped rod 2 and the second cylindrical rod 22 to slide downward through the third cylindrical rod 23 and the first cylindrical rod 21 respectively, it also drives the second rectangular block 25 to slide downward on the outside of the rectangular bar 252, without hindering the slide 253 from driving the second rectangular block 25 to slide through the rectangular bar 252.

[0049] Example 2: Figure 8 As shown, compared with Example 1, another embodiment of the present invention is: a transmission assembly is respectively provided at one end of the first cylindrical rod 21 away from the special-shaped rod 2, and the transmission assembly includes a first sprocket 211 fixed to one end of the first cylindrical rod 21, a second sprocket 26 is rotatably provided on the upper end of the first sprocket 211, and a third sprocket 27 is rotatably provided on one side of the second sprocket 26. The first sprocket 211, the second sprocket 26 and the third sprocket 27 are transmitted by a chain 28, a second motor 261 is fixed to one side of the second sprocket 26, and the second motor 261 is fixed to the rectangular frame 15 through a motor seat, a rectangular slider 29 is rotatably provided on one side of the third sprocket 27 through a pin shaft, and a second slide rail 291 is provided on one side of the rectangular slider 29, the second slide rail 291 is fixed to the upper end of the rectangular frame 15, the rectangular slider 29 is slidably provided inside the second slide rail 291, and the rectangular slider 29 is fixed to one side of the second slide rail 291 through a third spring 292.

[0050] Specifically, the second motor 261 is started to drive the second sprocket 26 to rotate, the second sprocket 26 drives the first sprocket 211 to rotate through the chain 28, and the first sprocket 211 drives the special-shaped rod 2 to rotate through the first cylindrical rod 21. When the special-shaped rod 2 moves downward, the special-shaped rod 2 drives the first sprocket 211 to slide downward through the first cylindrical rod 21. When the first sprocket 211 slides downward, the third sprocket 27 slides in the second slide rail 291 through the rectangular slider 29 and squeezes the third spring 292 to keep the chain 28 always in a tensioned state.

[0051] Working principle: When grinding the stainless steel welding wire, the stainless steel welding wire is passed through the inside of the cylinder 1, so that the stainless steel welding wire passes through the middle of each grinding paper 11, and each grinding paper 11 is wrapped around the outside of the stainless welding wire. Then, the first motor 142 is started to drive the gear 141 to rotate, and the gear 141 drives the corresponding gear rings 14 to rotate inside the cylinder 1. The gear rings 14 can drive each second grinding assembly to rotate, so that the grinding paper 11 is evenly distributed around the stainless steel welding wire. Multiple grinding papers 11 wrap the stainless steel welding wire at multiple angles, and can grind the stainless steel welding wire in all directions. Then, the winding device winds the stainless steel welding wire, so that the stainless steel welding wire slides between the grinding papers 11. The grinding papers 11 are evenly distributed around the stainless steel. At the same time, each grinding paper 11 pulls the stainless steel welding wire with the same force to prevent shaking when the stainless steel welding wire is pulled;

[0052] After the grinding paper 11 has been used for a period of time, it needs to be replaced regularly. By driving each gear ring 14 to rotate, the gear ring 14 drives the second grinding assembly to rotate in the cylinder 1, so that each second grinding assembly rotates to a side parallel to the first grinding assembly, and by driving the slide 253 to slide on the side of the electric slide rail 254, the slide 253 drives the special-shaped rod 2 to insert into the special-shaped through hole 112 through the second rectangular block 25, and at the same time makes the second cylindrical rod 22 located at the upper end of the first rectangular plate 13, and then drives the hydraulic rod 31 to extend, driving the third rectangular block 3 to slide downward, and the third rectangular block 3 drives the special-shaped rod 2 and the second cylindrical rod 22 to slide downward through the third cylindrical rod 23 and the first cylindrical rod 21 respectively, and the second cylindrical rod 22 drives the grinding paper 11 to move downward through the first rectangular plate 13, and stretches the second spring 133, so that the grinding paper 11 is not tightly attached to the side of the stainless steel welding wire at this time, and then drives the special-shaped rod 2 to rotate to replace the grinding paper 11 to prevent the stainless steel welding wire from deforming.
