Description

Technical Field

[0001] The present invention relates to the technical field of tank body forming, and particularly relates to a forming device for a transformer conservator tank body. Background Art

[0002] The transformer conservator tank body is an important component in a transformer for storing cooling oil. The high-precision welding of its tank body plays a crucial role in the performance and safety of the transformer. The tank body is usually formed by welding multiple sections of circular pipes to flexibly adjust the volume of the tank body to meet the requirements of different transformers. The structure formed by welding multiple sections of circular pipes can ensure the strength and stability of the conservator. The welded connection points can provide sufficient rigidity and strength, enabling the conservator to withstand the weight of the oil and external pressure and ensuring safe operation.

[0003] However, the existing welding processing method of the tank body has the following problems: Manual welding is usually involved in the processing of the tank body. During the welding process of the existing welding method, the position of the circular pipe needs to be continuously adjusted to ensure the integrity of the weld seam. The error during adjustment easily leads to a decrease in welding precision. Secondly, during manual welding, it is impossible to ensure the relative perpendicularity between the welding head and the connection seam of the circular pipe, resulting in uneven distribution of the welding material in the weld seam, thereby affecting the quality and strength of the welded part.

[0035] As Figure 1 andFigure 2 As shown, the support mechanism 3 includes a fixing plate 30, the fixing plate 30 is fixedly installed on the base 10, and a fixing portion 22 is also provided in the middle of the fixing plate 30.

[0036] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the fixing portion 22 includes through holes. Through holes are provided in the middle of both the support plate 20 and the fixing plate 30. T-shaped tubes 4 coaxial with the through holes are rotatably installed on the opposite surfaces of the two support plates 20 and the right end surface of the fixing plate 30. External gear rings 220 are rotatably installed on the T-shaped tubes 4. Activity grooves 221 are evenly provided along the circumferential direction of the inner wall of the external gear ring 220. Limiting plates 222 are slidably installed at positions corresponding to the horizontal sections of the T-shaped tubes 4 and the activity grooves 221 one by one. One end of the limiting plate 222 in contact with the circular tube is an arc surface. Driving members 223 for driving the corresponding external gear rings 220 are provided on the support plate 20 and the fixing plate 30. Limiting members 224 for pre-limiting the movement of the T-shaped tubes 4 are provided on the external gear rings 220.

[0037] As Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the limiting member 224 includes a T-shaped rod 2240. T-shaped rods 2240 are symmetrically provided on the limiting plate 222. Compression springs 2241 are installed between the vertical sections of the T-shaped rods 2240 and the corresponding limiting plates 222. Second waist grooves are provided at positions corresponding to the vertical sections of the T-shaped tubes 4 and the T-shaped rods 2240 one by one. Guide grooves 2242 corresponding to the T-shaped rods 2240 one by one are provided on both the support plate 20 and the fixing plate 30, and the guide grooves 2242 are right trapezoidal structures with inclined surfaces facing the through holes. The horizontal sections of the T-shaped rods 2240 slide through the corresponding limiting plates 222 and the corresponding second waist grooves and then are slidably engaged with the corresponding guide grooves 2242. Arc-shaped waist grooves are provided at positions corresponding to the T-shaped rods 2240 on the external gear rings 220, and the T-shaped rods 2240 movably penetrate through the corresponding arc-shaped waist grooves.

[0038] As Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, the extrusion part 23 includes a U-shaped plate 230. U-shaped plates 230 are arranged on the opposite faces of the two support plates 20. The U-shaped plates 230 are slidably connected to the corresponding support plates 20 through guide rods. Rectangular blocks 231 are installed on the upper end faces of the two vertical sections of the U-shaped plate 230. Shaft rods are symmetrically installed on the opposite faces of the two support plates 20 before and after through supports. Driving rods 232 are rotatably installed at both ends of the shaft rods. The driving rods 232 are in a V-shaped structure. An extrusion block 233 is hinged to one end of the driving rod 232 close to the through hole. The end of the extrusion block 233 that fits the circular tube is an arc surface. A waist-shaped groove is formed at the other end of the driving rod 232. Guide posts 234 that slide through the corresponding waist-shaped grooves are installed on the rectangular blocks 231. An actuator for driving the two U-shaped plates 230 to move towards each other is arranged on the supporting plate 11.

[0039] As Figure 1 , Figure 2 , Figure 3 and Figure 6 shown, the driving part 223 includes a spline sleeve 2230. The spline sleeve 2230 is rotatably installed on the support plate 20. A first straight gear 2231 that meshes with the corresponding external gear ring 220 is installed on the spline sleeve 2230. A spline shaft 2232 is rotatably installed on the supporting plate 11 through a first shaft plate, and the spline shaft 2232 slidably penetrates through the two spline sleeves 2230. A second straight gear 2233 that meshes with the corresponding external gear ring 220 is rotatably installed on the fixing plate 30. An inclined groove 2234 is formed on the limiting plate 222. A cylinder 2235 that slides through the corresponding inclined groove 2234 is installed on the external gear ring 220.

[0040] As Figure 1 and Figure 6 shown, the actuator includes a bidirectional screw 235. The bidirectional screw 235 is rotatably installed on the supporting plate 11 through a second shaft plate. The longitudinal sections of the two U-shaped plates 230 are respectively threadedly connected to the two threaded sections of the bidirectional screw 235, and the bidirectional screw 235 also movably penetrates through the two support plates 20.

[0041] During specific operation, the external clamping device inserts the circular tube into the through hole of the support plate 20. Then, the external first motor installed on the supporting plate 11 drives the spline shaft 2232 to rotate. The spline shaft 2232 drives the corresponding first spur gear 2231 to rotate through the spline sleeve 2230. The first spur gear 2231 drives the corresponding external tooth ring 220 to rotate. With the cooperation of the T-shaped rod 2240 and the guide groove 2242, the rotation of the T-shaped tube 4 is restricted. Therefore, when the external tooth ring 220 rotates, it will first push the limiting plate 222 towards the circular tube through the cooperation of the column 2235 and the inclined groove 2234, so that the limiting plate 222 squeezes the circular tube. At the same time, the limiting plate 222 will drive the T-shaped rod 2240 to synchronously move along the radial direction of the T-shaped tube 4, and the T-shaped rod 2240 slides in the arc-shaped waist groove on the external tooth ring 220 to ensure that the T-shaped rod 2240 can normally move along the radial direction of the T-shaped tube 4. At the same time, through the contact guidance of the inclined surface of the guide groove 2242, the T-shaped rod 2240 moves towards the side away from the U-shaped plate 230 until the T-shaped rod 2240 disengages from the guide groove 2242 to release the restriction on the rotation of the T-shaped tube 4. At this time, the external first motor stops rotating. Then, the external second motor installed on the supporting plate 11 drives the bidirectional screw 235 to rotate. The bidirectional screw 235 drives the two U-shaped plates 230 to approach each other. The U-shaped plate 230 drives the driving rod 232 to rotate through the rectangular block 231 and the guide post 234. The driving rod 232 drives the extrusion block 233 to squeeze the circular tube. At this time, the driving rod 232 cannot rotate further. When the bidirectional screw 235 continues to rotate, it drives the corresponding support plates 20 to approach each other through the driving rod 232, so that the circular tubes on the two support plates 20 are butted against each other. At the same time, through the extrusion and limitation of the circular tube by the extrusion block 233 and the extrusion and fixation of the circular tube by the fixing part 22, the stability of the circular tube during the moving butt joint process is ensured in a double-fixing manner.

[0042] As Figure 1 , Figure 2 and Figure 6 shown, the welding part 21 includes a sliding plate 210. The sliding plates 210 are slidably installed up and down on the opposite surfaces of the support plate 20. Axial columns 211 are symmetrically installed front and back on the upper end surface of the sliding plate 210. A rectangular plate 212 is slidably installed on the axial columns 211 together. First waist grooves 213 are formed at positions corresponding to the axial columns 211 on the rectangular plate 212. Connecting plates 214 are slidably installed at positions corresponding to the sliding plate 210 on the upper and lower end surfaces of the rectangular plate 212, and the connecting plates 214 are fixedly connected to the corresponding two axial columns 211. A T-shaped sleeve 215 is arranged in the middle of the rectangular plate 212. The vertical end of the T-shaped sleeve 215 slidably penetrates the rectangular plate 212. A tension spring 216 is arranged between the horizontal end of the T-shaped sleeve 215 and the rectangular plate 212. A welding head 217 is installed in the T-shaped sleeve 215. An adjusting part 218 for adjusting the position of the welding head 217 is arranged on the right side of the rectangular plate 212.

[0043] As Figure 1 , Figure 2 and Figure 8 shown, the adjusting member 218 includes a stepper motor 2180. The stepper motor 2180 is fixedly installed on the skateboard 210 on the right side. The output shaft of the stepper motor 2180 rotatably penetrates through the corresponding two connecting plates 214 and is then installed with a winding wheel 2181. A notch 2182 is opened on the right side of the rectangular plate 212. A baffle 2183 is rotatably installed in the notch 2182 through a torsion spring rod. A guide wheel 2184 is rotatably installed on the rectangular plate 212. A rectangular hole is also opened on the rectangular plate 212. A rope 2185 is wound around the winding wheel 2181. One end of the rope 2185 bypasses the guide wheel 2184 and then passes through the rectangular hole and is connected to the baffle 2183.

[0044] As Figure 6 shown, a support plate 2150 is fixedly installed at the lower part of the T-shaped sleeve 215. A guide rod that slidably penetrates through the rectangular plate 212 is installed on the upper end surface of the support plate 2150. Axle seats are symmetrically installed on the front and rear of the lower end surface of the support plate 2150. A rotating shaft is rotatably installed at the lower part of the axle seat. Rollers 2151 that are attached to the outer wall of the circular tube are installed at both the left and right ends of the rotating shaft.

[0045] As Figure 7 shown, rubber rollers 2330 are rotatably installed on the arc surface of the extrusion block 233 along its trajectory. On the one hand, the rubber rollers 2330 ensure the extrusion of the circular tube by the extrusion block 233 and at the same time increase the friction force received by the circular tube to ensure that the circular tube can be driven to move horizontally. On the other hand, they are used to reduce the hindrance to the circumferential rotation of the circular tube and ensure the smoothness and stability of the rotational welding of the circular tube.

[0046] During specific operation, the external electric telescopic rod installed on the support plate 20 pulls the skateboard 210 to move downward. The skateboard 210 then drives the rectangular plate 212 to move downward through the shaft column 211 and the connecting plate 214. The rectangular plate 212 then drives the T-shaped sleeve 215, the welding head 217 and the rollers 2151 to move towards the circular tube until the rollers 2151 are in contact with the circular tube. After that, the stepper motor 2180 drives the winding wheel 2181 to rotate. The winding wheel 2181 winds the rope 2185. The rope 2185 then pulls the baffle 2183 to rotate downward, from the horizontal state to the vertical state. At this time, the baffle 2183 abuts against the inner wall of the notch 2182 and cannot rotate further. When the stepper motor 2180 continues to rotate, the baffle 2183 remains in the vertical state. The rope 2185 pulls the baffle 2183 and the rectangular plate 212 to move to the left until the baffle 2183 is in contact with the right end face of the circular tube. The driven rectangular plate 212 then drives the welding head 217 to move to directly above the weld seam to improve the welding quality.

[0047] After that, the external electric telescopic rod pulls the rectangular plate 212 to move further downward to stretch the tension spring 216, increasing the force on the T-shaped sleeve 215 and improving the stability of the welding head 217. Then, the external first motor continues to drive the spline shaft 2232 to rotate. The spline shaft 2232 drives the external gear ring 220 to rotate through the first spur gear 2231, so as to drive the circular tube to rotate while maintaining the extrusion and fixation of the circular tube, ensuring the integrity of the welding. After that, the left end of the welded circular tube is pushed through the through hole on the fixing plate 30 until it abuts against the blocking plate 12, releasing the fixation of the circular tube. Then, the electric slider (not shown in the figure) drives the supporting plate 11 and the fixing part 22 to move to the right, and the supporting plate 20 on the right side disengages from the circular tube, so that the external clamping device can clamp the circular tube to be welded and pass it through the through hole of the supporting plate 20 on the right side. Then, repeat the above operations to fix the circular tube and butt it with the welded circular tube. Then, the external servo motor installed on the fixing plate 30 drives the corresponding fixing part 22 through the second spur gear 2233 to clamp and support the left end of the leftmost circular tube after welding, so as to ensure the stability of the welded tank body part. Then, the welding part 21 adjusts the welding position, and then the external second motor and the external servo motor drive the circular tube to rotate synchronously for welding processing. After welding the tank body step by step to the required size, the fixation of the circular tube is released, and the welded tank body is clamped and fixed by the external clamping device. Then, the electric slider drives both supporting plates 20 to completely disengage from the welded tank body, and then the external clamping device removes the welded tank body, and then successively feeds the circular tubes to be welded for welding processing.
