Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of distribution pipe processing, and particularly relates to a distribution pipe assembly and a processing technology thereof. BACKGROUND

[0002] The heat exchanger is an energy-saving device for realizing heat transfer between materials of two or more fluids at different temperatures, and is used for transferring heat from a fluid at a higher temperature to a fluid at a lower temperature, so that the temperature of the fluid meets the process requirements and improves the energy utilization rate.

[0003] At present, a distribution pipe is disclosed in Chinese Patent No. CN112013710A and published on December 1, 2020, which has a pipe wall and an inner cavity. The pipe wall of the distribution pipe is provided with a through hole. The pipe wall of the distribution pipe includes an arc-shaped wall and a bottom wall. The arc-shaped wall has a first side edge and a second side edge. The bottom wall has a first side edge and a second side edge. The bottom wall is generally flat. The first side edge of the arc-shaped wall is connected to the first side edge of the bottom wall. The second side edge of the arc-shaped wall is connected to the second side edge of the bottom wall. A heat exchanger includes a collecting pipe, a distribution pipe, and a plurality of heat exchange pipes. The collecting pipe has a first end, a second end, a pipe wall, and an inner cavity. The distribution pipe has a first end and a second end. The first end of the distribution pipe is a refrigerant inlet. The second end of the distribution pipe extends into the inner cavity of the collecting pipe from the first end of the collecting pipe. The through hole connects the inner cavity of the collecting pipe and the inner cavity of the distribution pipe. The plurality of heat exchange pipes are arranged along the length direction of the collecting pipe. Each heat exchange pipe has a first end and an inner cavity. The first end of the heat exchange pipe penetrates the pipe wall of the collecting pipe and is inserted into the inner cavity of the collecting pipe. The inner cavity of the heat exchange pipe is in communication with the inner cavity of the collecting pipe.

[0004] During the working process of the heat exchanger, the refrigerant can enter the inner cavity of the distribution pipe through the first end of the distribution pipe. The refrigerant flows in the distribution pipe from the first end to the second end. The refrigerant can enter the inner cavity of the collecting pipe through the through hole on the pipe wall of the distribution pipe. The first end of each heat exchange pipe penetrates the pipe wall of the collecting pipe. The first end of the heat exchange pipe is provided with an opening to connect the inner cavity of the heat exchange pipe and the inner cavity of the collecting pipe. The refrigerant in the collecting pipe can enter the inner cavity of the heat exchange pipe through the first end of the heat exchange pipe. The refrigerant can be heat-exchanged in the inner cavity of the heat exchange pipe.

[0005] When the distribution pipe is fixed in the collecting pipe, the end of the distribution pipe is usually welded with the end of the collecting pipe. If the length of the collecting pipe is relatively long, the distribution pipe that needs to be inserted also needs to have a matching length. However, the distribution pipe body in the collecting pipe is prone to position deviation due to its own gravity, which is not conducive to the stable installation of the distribution pipe in the collecting pipe.

[0037] Then, after the piston rod of the driving cylinder moves upward, the piston rod can drive the lifting plate to move upward through the connecting table, then the lifting plate can drive the two sliders to move toward each other through the inclined surface, and the reset spring is compressed, at this time, the four pressing claws on the upper side of the two sliders can simultaneously abut against the extrusion ring, under the pressure of the pressing claws, the extrusion ring at the position of the pressing claws can be deformed and abut against the outer wall of the distribution pipe body, thereby completing the connection of the support plate on the distribution pipe body; When the two sliders move toward each other and the pressing claws do not abut against the extrusion ring, the positioning ball in the spherical groove will first abut against the outer wall of the support plate, thereby positioning the position of the support plate in the first clamping groove through the positioning ball, and when the pressing claws abut against the extrusion ring, the position of the extrusion ring is prevented from being deviated, thereby facilitating the stable abutment of the pressing claws on the extrusion ring;

[0073] After the piston rod of the driving cylinder 3561 moves upward, the piston rod can drive the lifting plate 3562 to move upward through the connecting table 3565, and then the lifting plate 3562 can drive the two sliders 354 to move toward each other through the inclined surface part 3563, and the reset spring 3567 is compressed, at this time, the four pressing claws 355 on the upper side of the two sliders 354 can be tightly pressed on the extrusion ring 22 at the same time, and under the pressure of the pressing claws 355, the extrusion ring 22 at the position of the pressing claws 355 can be deformed and tightly pressed on the outer wall of the distribution pipe body 1, thereby completing the connection of the support plate 2 on the distribution pipe body 1; wherein when the two sliders 354 move toward each other and the pressing claws 355 are not in contact with the extrusion ring 22, the positioning ball 3543 in the spherical groove 3542 will first tightly press on the outer wall of the support plate 2, thereby positioning the position of the support plate 2 in the first clamping groove 352 through the positioning ball 3543, and when the pressing claws 355 are in contact with the extrusion ring 22, the position of the extrusion ring 22 is prevented from being deviated, and finally the pressing claws 355 can be stably pressed on the extrusion ring 22;

[0074] Because the pressing claws 355 exert pressure on the extrusion ring 22 to force it to deform, the surface of the extrusion ring 22 will leave indentations and burrs, which will affect the assembly and use performance of the product; therefore, after the pressing claws 355 exert the extrusion force on the extrusion ring 22, the piston rod of the driving cylinder 3561 is lowered and the two sliders 354 are driven to move away from each other by a distance by the elastic recovery of the reset spring 3567, so that the pressing claws 355 are located at the position of the outer wall of the extrusion ring 22, and the positioning ball 3543 still maintains the pressing action on the support plate 2, so that the support plate 2 is tightly pressed on the movable shaft 4 under the action of the positioning ball 3543, at this time, the driving gear 3514 is started, so that the driving gear 3514 drives the connecting teeth 431 to rotate back and forth, and then the connecting teeth 431 drive the movable shaft 4 to rotate back and forth, and the movable shaft 4 drives the support plate 2 to swing back and forth relative to the pressing claws 355, and finally the burrs on the outer wall of the extrusion ring 22 are scraped off by the pressing claws 355, so that the burrs on the outer wall of the extrusion ring 22 are removed by the pressing claws 355;

[0075] After the piston rod of the driving cylinder 3561 continues to move downward, the two sliders 354 continue to move away from each other, and the positioning ball 3543 can be moved away from the support plate 2, thereby facilitating the subsequent removal of the support plate 2 from the first clamping groove 352, and finally the rapid connection of multiple support plates 2 on the distribution pipe body 1 is completed.
