Detailed implementation mode

[0027] The present invention will be further described below in conjunction with the accompanying drawings: As Figure 1 — Figure 10As shown in the figure, this embodiment provides a PPH purification tank coiling and welding machine, which includes a first clamping system 1, a second clamping system 2, and a pushing and welding system 3. The first clamping system 1 has a first clamping and rotating end that can be translated, and the second clamping system 2 has a second clamping and rotating end that can be translated. The pushing and welding system 3 is installed at the middle position between the first clamping and rotating end and the second clamping and rotating end in a liftable manner. The first clamping and rotating end and the second clamping and rotating end are symmetrically arranged with each other. The first clamping and rotating end and the second clamping and rotating end clamp the PPH plate. At each moment of the action, the first clamping and rotating end and the second clamping and rotating end are axisymmetric with respect to the pushing and welding system 3. After the first clamping and rotating end and the second clamping and rotating end clamp the PPH plate, they rotate 180 degrees at a constant speed in opposite directions. The pushing and welding system 3 has a heating area. The pushing and welding system 3 includes a pushing and welding upper beam 31, a pushing and welding lower beam 32, and a pushing and welding lifting device 33. The pushing and welding upper beam 31 and the pushing and welding lower beam 32 are both installed on the pushing and welding lifting device 33 in a liftable and sliding manner. The heating area is arranged between the pushing and welding upper beam 31 and the pushing and welding lower beam 32. The top of the pushing and welding upper beam 31 is provided with an arc pushing surface 311. The first clamping and rotating end and the second clamping and rotating end respectively clamp both ends of the PPH plate, and then bend the PPH plate. The arc pushing surface 311 at the top of the pushing and welding upper beam 31 pushes the middle part of the PPH plate to assist in bending the PPH plate. The first clamping and rotating end and the second clamping and rotating end flip both ends of the PPH plate to the heating area for heating and welding, with high production efficiency.

[0028] The pushing and welding lifting device 33 includes a lifting column 331, a transverse moving plate 332, and a lifting motor 333. In order to enable the pushing and welding upper beam 31 and the pushing and welding lower beam 32 to achieve horizontal fine adjustment, the transverse moving plate 332 is installed on the transverse moving slide rail through a slider. The movement and positioning of the slider along the transverse moving slide rail belong to the prior art and will not be elaborated here. The lifting motor 333 is installed on the transverse moving plate 332. The output end of the lifting motor 333 is provided with a gear, and a rack meshing with the gear is provided on the lifting column 331. The lifting column 331 is installed on the transverse moving plate 332 in a liftable and sliding manner through a slide rail and slider sliding pair. The lifting column 331 is provided with a lifting plate 334 and two heating and clamping sliders 335. A heating and clamping guide rail 336 is installed on the lifting plate 334. A heating and clamping cylinder 337 is arranged between the two heating and clamping sliders 335. Both heating and clamping sliders 335 are slid through the heating and clamping guide rail 336. The heating and clamping cylinder 337 drives the two heating and clamping sliders 335 to open and close. The pushing and welding upper beam 31 and the pushing and welding lower beam 32 are respectively installed on the two heating and clamping sliders 335. Electric heating plates are provided at adjacent positions of the pushing and welding upper beam 31 and the pushing and welding lower beam 32. The two electric heating plates form the heating area.

[0029] To illustrate the working principle of this application, as Figure 4As shown, the PPH plate is first transported by a forklift, manual or conveyor belt to the first clamping rotating end, the second clamping rotating end and between the top push welding upper beam 31 and the top push welding lower beam 32, as shown in FIG. Figure 5 As shown, the first clamping rotating end and the second clamping rotating end rotate at the same speed in opposite directions, and the lifting motor 333 drives the top push welding upper beam 31 to rise, assisting the PPH plate to bend upward, as shown in FIG. Figure 6 As shown, due to the increase in the bending degree of the PPH plate, the resistance torque of the middle area of the PPH plate to the first clamping rotating end and the second clamping rotating end caused by its own gravity decreases, and the lifting motor 333 drives the top push welding upper beam 31 and the top push welding lower beam 32 to descend to the joint height of the side of the PPH plate, and the heating clamping cylinder 337 drives the two heating clamping slide blocks 335 to open, so that the top push welding upper beam 31 and the top push welding lower beam 32 are opened, which is convenient for the PPH plate to extend into the joint side. Figure 7 As shown, the heating clamping cylinder 337 drives the two heating clamping slide blocks 335 to move closer, so that the top push welding upper beam 31 and the top push welding lower beam 32 are close to each other, which is convenient for heating and welding of the side joint of the PPH plate.
