Description

TECHNICAL FIELD

[0001] The present application relates to the field of heat exchange pipe processing equipment, and particularly relates to a heat exchange pipe processing production line for cooling towers. BACKGROUND

[0002] The heat exchange pipe in the cooling tower is a key component for heat exchange, and its function is to transfer heat between the medium to be cooled and the external cooling medium (such as water or air), so as to reduce the temperature of the medium to be cooled.

[0003] The traditional processing method of the heat exchange pipe is to first extrude the metal strip into a tubular shape, then sew the weld seam, then polish the surface of the weld seam, and finally cut the polished heat exchange pipe into multiple sections according to the size. The entire production line process mainly includes forming, welding, polishing, cutting and conveying, thereby realizing the entire heat exchange pipe processing process.

[0004] Since the end of the cut heat exchange pipe usually has burrs, which will affect the subsequent installation of the heat exchange pipe, but since the production and processing of the heat exchange pipe is a continuous process, directly polishing the end of the heat exchange pipe requires stopping the entire production and processing process of the heat exchange pipe. Therefore, the cut heat exchange pipe is usually transferred to other locations for additional end polishing equipment to polish the end of the cut heat exchange pipe. In the process of transferring the heat exchange pipe, a lot of time is often spent, which greatly reduces the production efficiency of the heat exchange pipe, and there are obvious deficiencies.

[0057] At this time, the heat exchange pipe 1 on the toothed plate 708 closest to the pipe feeding frame 702 will fall on the guide bending wheel 703, and the control system starts the pipe feeding motor 7051, the output shaft of the pipe feeding motor 7051 drives one of the guide bending wheels 703 to rotate, and under the transmission of the chain wheel chain 7052, the plurality of guide bending wheels 703 rotate simultaneously in the same direction, so that the heat exchange pipe 1 on the pipe feeding frame 702 is continuously transported to the direction of the pipe bending machine 8.

[0058] At the same time, the piston rod of the pipe feeding cylinder 713 extends and pushes the pipe turning shaft 711 to rotate forward, and at this time the pipe turning plate 712 pushes the heat exchange pipe 1 on the roller 704 into the tooth gap of the toothed plate 708, and the process is repeated, so that the heat exchange pipe 1 is continuously transported to the direction of the pipe bending machine 8.

[0059] When the piston rod of the pipe feeding cylinder 713 retracts and pushes the pipe turning shaft 711 to rotate reversely, the pipe turning plate 712 at this time pushes the heat exchange pipe 1 on the roller 704 to the elastic belt 707 on the top of the pipe storage frame 706, and the elastic belt 707 deforms and descends, thereby transferring the continuously transported heat exchange pipe 1, and then the workers regularly handle the heat exchange pipe 1 on the elastic belt 707.

[0060] The implementation principle of the heat exchange pipe processing production line for cooling towers in the embodiment of the application is as follows: first, the workers adjust the positions of the cutting plate 602 and the polishing plate 603 according to the designed length of the heat exchange pipe 1, and adjust the fixed positions of the cutting oil cylinder 92 and the polishing oil cylinder 93, and then the metal strip material wound on the unwinding machine 2 is processed into the heat exchange pipe 1 through the forming machine 3, the welding machine 4 and the polishing machine 5, and then the heat exchange pipe 1 is sequentially slid to the guide wheel 102 on the cutting frame 101 and the supporting wheel 95 on the supporting frame 94 at a fixed speed.

[0061] When it is necessary to cut the continuously transported heat exchange pipe 1, the control system starts the cutting cylinder 103 and the cutting oil cylinder 92, the piston rod of the cutting oil cylinder 92 extends at the same speed as the transportation of the heat exchange pipe 1, and the piston rod of the cutting cylinder 103 drives the cutting wheel 104 to press the heat exchange pipe 1 on the guide wheel 102, so that the heat exchange pipe 1 and the cutting plate 602 remain relatively stationary.

[0062] At the same time, the control system starts the cutting motor 606 and the cutting cylinder 608, the output shaft of the cutting motor 606 drives the cutting wheel 607 to rotate, and the piston rod of the cutting cylinder 608 pushes the cutting seat 605 to approach the heat exchange pipe 1, so that the heat exchange pipe 1 is cut off, and then the piston rod of the cutting cylinder 608 retracts and drives the cutting seat 605 to reset.

[0063] At the same time, the control system starts the pushing-grinding cylinder 93, the piston rod of the pushing-grinding cylinder 93 pushes the grinding plate 603 to slide at the same speed as the heat exchange pipe 1 is conveyed, and the control system starts the fixing-grinding cylinder 113, the grinding motor 614, the pushing-grinding cylinder 612 and the rotating motor 122, the piston rod of the fixing-grinding cylinder 113 pushes the pressing grinding wheel 114 to continuously approach the heat exchange pipe 1, so that the heat exchange pipe 1 is pressed on the guide wheel 112, thereby keeping the cut heat exchange pipe 1 and the tube seat of the grinding plate 603 relatively static.

[0064] The output shaft of the grinding motor 614 drives the grinding wheel 615 to rotate, the piston rod of the pushing-grinding cylinder 612 pushes the grinding seat 613 to approach the heat exchange pipe 1, so that the rotating grinding wheel 615 is attached to the surface of the end of the heat exchange pipe 1, and the output shaft of the rotating motor 122 drives the gear ring 121 to rotate through the gear 123, the gear ring 121 drives the mounting ring 610 to synchronously rotate, so that the end of the heat exchange pipe 1 is circumferentially ground, and then the piston rods of the fixing-grinding cylinder 113 and the pushing-grinding cylinder 612 are retracted.

[0065] In the process of conveying the cut heat exchange pipe 1 on the roller 704 of the conveying frame 701, the control system starts the moving pipe cylinder 710, the piston rod of the moving pipe cylinder 710 extends and drives the movable toothed plate 709 to rotate, because the movable toothed plate 709 and the fixed toothed plate 708 are arranged in a staggered manner, at this time, the rotating movable toothed plate 709 moves the heat exchange pipe 1 in the tooth gap of the fixed toothed plate 708 by one tooth gap distance to the direction close to the pipe conveying frame 702.

[0066] At this time, the heat exchange pipe 1 on the fixed toothed plate 708 closest to the pipe conveying frame 702 falls on the guide bending wheel 703, and the control system starts the pipe conveying motor 7051, the output shaft of the pipe conveying motor 7051 drives one of the guide bending wheels 703 to rotate, and under the transmission of the chain wheel and chain 7052, the plurality of guide bending wheels 703 rotate simultaneously in the same direction, so that the heat exchange pipe 1 on the pipe conveying frame 702 is continuously conveyed to the direction of the pipe bending machine 8.

[0067] At the same time, the piston rod of the pipe conveying cylinder 713 extends and drives the pipe conveying shaft 711 to rotate forward, at this time, the pipe conveying plate 712 pushes the heat exchange pipe 1 on the roller 704 into the tooth gap of the fixed toothed plate 708, and the process is repeated, so that the heat exchange pipe 1 is continuously conveyed to the direction of the pipe bending machine 8.

[0068] When the piston rod of the pipe conveying cylinder 713 retracts and drives the pipe conveying shaft 711 to rotate reversely, at this time, the pipe conveying plate 712 pushes the heat exchange pipe 1 on the roller 704 to the elastic belt 707 on the top of the pipe storage frame 706, the elastic belt 707 is deformed and falls, thereby transferring the continuously conveyed heat exchange pipe 1, and then the workers can periodically process the heat exchange pipe 1 on the elastic belt 707.

[0069] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
