[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example 1

[0038] See also Figure 1-Figure 9 ;

[0039] A vertical pressurizing and shaping device for preparing a water heater inner tank, comprising a frame 1 and a vertical pressurizing and shaping device 2 installed on the surface of the frame 1;

[0040] The vertical pressure shaping device 2 includes a pressing component 21, a welding component 22, a shaping component 23, an upper component 24 and a PLC controller 25. The pressing component 21, the shaping component 23 and the upper component 24 are sequentially installed on the surface of the frame 1 from top to bottom, the welding component 22 is installed inside the pressing component 21, the PLC controller 25 is installed on the ground and located on one side of the frame 1, the PLC controller 25 is electrically connected to an external power supply, and the PLC controller 25 is electrically connected to the pressing component 21, the welding component 22 and the shaping component 23 respectively.

[0041] It should be noted that, in this embodiment: the surface of the frame 1 is provided with holes, holes and grooves that are compatible with the external dimensions of the vertical pressure shaping device 2 .

[0042] It should be noted that, in this embodiment: the PLC controller 25 has a built-in processing program.

[0043] In the present embodiment: when in use, the plate 248 that has been cut to size and punched is first placed in the plate placing part 247, and then the processing program inside the PLC controller 25 is run. The program runs the PLC controller 25 to first control the first hydraulic telescopic column 212 to extend downward, and the first hydraulic telescopic column 212 extends downward to drive the pressure seat 211 to move downward synchronously along the surface of the frame 1, and the pressure seat 211 moves downward to drive the conical seat 214 and the slide 215 to move downward synchronously, and the slide 215 moves downward to drive the rotating shaft 218, the negative pressure roller 219 and the first driving motor 2110 to move downward synchronously, and the negative pressure roller 219 first contacts with the plate 248 during the movement and synchronously drives the plate 248 to descend, and the plate 248 descends and moves to the semi-arc The inside of the groove portion 241 is subjected to bidirectional extrusion from the negative pressure roller 219 and the semi-arc groove portion 241, thereby deforming and fitting tightly with the inner wall of the semi-arc groove portion 241. When the plate 248 contacts the surface of the arc joint 242 inside the semi-arc groove portion 241, the conical seat 214 also just moves to the position of the extrusion portion 249 and contacts the extrusion portion 249. As the first hydraulic telescopic column 212 continues to extend downward, the pressure seat 211 also continues to move downward. As the pressure seat 211 continues to move downward, under the elastic force of the first spring 216, the negative pressure roller 219 always presses the surface of the plate 248 and keeps the position fixed. At the same time, the conical seat 214 descends and synchronously pushes the extrusion portion 249 to move to one side, and the extrusion portion 24 9 moves to one side and synchronously drives the upper arc extrusion block 244 to move along the surface of the straight portion 243 toward the side of the semi-arc groove portion 241, and squeezes the plate 248 exposed outside the semi-arc groove portion 241 through the inner arc groove portion 2441, so that the plate 248 is completely pressed into a cylindrical shape, and the two groups of upper arc extrusion blocks 244 do not contact each other. The gap between the two groups of upper arc extrusion blocks 244 is adapted to the outer dimensions of the roller welding head 228, and the roller welding head 228 corresponds to the welding position of the plate 248. At the same time, the upper arc extrusion block 244 moves synchronously and drives the shaft rod 245 to move and squeeze the third spring 246. When the first hydraulic telescopic column 212 extends to the set value, the PLC controller 25 controls the first hydraulic telescopic column 212 to extend to the set value. 12 stops running. At the same time, one end of the upper arc-shaped extrusion block 244 just contacts the second limiter 2432 inside the guide groove 2431. The second limiter 2432 sends data information to the PLC controller 25. The PLC controller 25 controls the second drive motor 2210 to be powered on and run. The second drive motor 2210 is powered on and rotates synchronously to drive the threaded screw 222 to rotate. The threaded screw 222 rotates and drives the slide 223 to move along the surface of the threaded screw 222 and the surface of the guide column 221 toward the second drive motor 2210. The slide 223 moves and drives the guide block 224 to move synchronously. The guide block 224 moves and drives the guide roller 226 and the roller welding head 228 to move. In the initial state,The guide roller 226 is located inside the limiting groove 2274 at the position of the slope section 2273 in the guide frame 227 and contacts one of the first limiters 2275 on the inner wall of the limiting groove 2274. The straight section 2272 corresponds to the position of the welding position of the plate 248. When the guide block 224 moves, the guide roller 226 also moves in the limiting groove 2274 and disengages from one of the first limiters 2275 on the inner wall of the limiting groove 2274. When the guide roller 226 moves from the slope section 2273 to the position of the straight section 2272, it is squeezed by the straight section 2272 and the guide roller 226 starts to move downward. The downward movement of the guide roller 226 synchronously drives the roller welding head 228 to move downward and compress the second spring 225. The welding head 228 descends and contacts the welding part of the plate 248 and performs welding operation on the welding part of the plate 248. As the guide block 224 continues to move toward the side of the second drive motor 2210, the guide roller 226 also synchronously moves on the inner wall of the limiting groove 2274 at the position of the straight section 2272 and performs welding operation on the welding part of the plate 248. When the guide roller 226 moves from the straight section 2272 to another set of slope sections 2273, the guide roller 226 is no longer squeezed by the straight section 2272. Under the elastic force of the second spring 225, the guide roller 226 and the roller welding head 228 are synchronously reset and do not contact the welding part of the plate 248, thereby stopping the welding operation. When the guide roller 226 and the inner wall of the limiting groove 2274 are moved, the guide roller 226 is moved to the inner wall of the limiting groove 2274. When the plate 248 is in contact with another set of first stoppers 2275 of the wall, the PLC controller 25 controls the second drive motor 2210 to stop running, and then the PLC controller 25 controls the first hydraulic telescopic column 212 to run and drive the plate 248 on the surface of the negative pressure roller 219 to rise to the position of the lower arc extrusion block 232, and then the PLC controller 25 controls the first hydraulic telescopic column 212 to stop running. During this process, the PLC controller 25 also synchronously controls the operation of the external negative pressure device to extract the air inside the negative pressure roller 219 so that the inside of the negative pressure roller 219 is in a negative pressure state, so that the plate 248 is tightly adsorbed on the surface of the negative pressure roller 219 and keeps the shape fixed, and then the PLC controller 25 controls the first drive motor 2110 to be powered on and run. The first drive motor 2110 is powered on and rotated to drive the rotating shaft 218 and the negative pressure roller 219 to rotate synchronously, and then the PLC controller 25 controls the second hydraulic telescopic column 231 to operate. The second hydraulic telescopic column 231 extends and drives the two groups of lower arc-shaped extrusion blocks 232 to move toward the side of the negative pressure roller 219. The two groups of lower arc-shaped extrusion blocks 232 move synchronously or move alternately and progressively to press and shape the plate 248 on the surface of the negative pressure roller 219. After the operation is completed, the PLC controller 25 controls the first drive motor 2110 to stop running, and then resets the second hydraulic telescopic column 231 under control, then removes the cylindrical plate 248, and then resets other components through the PLC controller 25.

The slide 215 moves downward to drive the rotating shaft 218, the negative pressure roller 219 and the first driving motor 2110 to move downward synchronously.
