Description

Technical Field

[0001] This utility model relates to the field of evaporator processing, and more specifically, to an evaporator tube expansion device. Background Technology

[0002] The evaporator is a very important component among the four major refrigeration components. Low-temperature condensed liquid passes through the evaporator and exchanges heat with the outside air, vaporizing and absorbing heat to achieve the cooling effect.

[0003] To achieve better heat exchange, evaporators are equipped with multiple heat exchange pipes. To facilitate installation inside the evaporator, the ends of these pipes undergo pre-expansion. This expansion process requires the use of expansion equipment. Traditional expansion equipment typically uses an expansion head attached to the output shaft of a cylinder for reciprocating expansion. This method can only operate on a single pipe at a time. Furthermore, different evaporators use pipes of varying lengths, requiring precise adjustments to the cylinder's output distance when expanding pipes of different specifications. Additionally, the reciprocating movement of the expansion head during expansion inevitably attracts dust and other debris, which can be forced into the pipe during expansion, potentially affecting its quality.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

A top head 5 is installed on the mounting seat 4. An adjustment hole 6 is opened along the center of the end of the table 1 away from the transverse plate 3. A movable seat 7 is correspondingly provided on the adjustment hole 6. An assembly frame 8 is fixedly installed on the top of the movable seat 7. A tube expansion head 9 is fixedly installed on the side wall of the assembly frame 8 facing the transverse plate 3. A plurality of support seats 10 are fixedly installed at the center of the top of the table 1. When the tube expansion head 9 moves to a position close to the transverse plate 3, the tube expansion head 9 and the top head 5 are collinearly arranged.

[0028] Place the evaporator pipe to be expanded on the support base 10, adjust the position of the horizontal sliding plate 3 to support one end of the pipe, and then adjust the moving base 7 to move closer to the horizontal sliding plate 3, driving the assembly frame 8 and the expansion head 9 to move towards the other end of the pipe. When the expansion head 9 is inserted into the pipe and continues to move, the end of the pipe can be expanded.

[0029] An extension frame 11 is fixedly installed at the end of the tabletop 1 away from the transverse sliding plate 3. An adjusting cylinder 12 is fixedly installed at the bottom of the extension frame 11. A push rod 13 is fixedly installed at the output shaft end of the adjusting cylinder 12. Several connecting parts 14 are slidably installed on the end face of the push rod 13 away from the adjusting cylinder 12. The top of the connecting parts 14 passes through the adjusting hole 6, and the bottom of the moving seat 7 is fixedly installed on the top of the corresponding connecting parts 14. The adjusting cylinder 12 drives the push rod 13 to move, and the movement of the push rod 13 can drive the moving seat 7 to move synchronously through the connecting parts 14.

[0030] The adjustment holes 6 are arranged in a radial pattern on the tabletop 1, with the central adjustment hole 6 extending along the length of the tabletop 1. The two ends of the adjustment holes 6 on both sides are also extending along the length of the tabletop 1. The spacing between the ends of the adjustment holes 6 closer to the center of the tabletop 1 is greater than the spacing between the ends of the adjustment holes 6 closer to the ends of the tabletop 1. This arrangement allows the expansion tube heads 9 to be close together when located in the end area of ​​the tabletop 1, facilitating collective cleaning.

[0031] A T-shaped groove 131 is provided on the side wall of the push rod 13 away from the adjusting cylinder 12, which is arranged along its length. The connecting member 14 includes a stop block 144 that is slidably installed in the T-shaped groove 131.

The top of the column 142 is provided through the adjusting hole 6, and the bottom of the movable seat 7 is fixedly installed at the top end of the column 142. When the push rod 13 moves, it will drive the stop block 144 to move synchronously through the T-slot 131. The movement of the stop block 144 will drive the right angle plate 141 and the column 142 to move through the sliding column 143. When the column 142 moves, it will make corresponding adjustments along the adjustment hole 6, so that the column 142 can reverse the movement and drive the sliding column 143 and the stop block 144 to slide and adjust in the T-slot 131 through the right angle plate 141.

[0032] A tray 15 is fixedly installed on the top of the extension rack 11. The tray 15 can hold some auxiliary tools. A reinforcing rack 16 is fixedly installed on the bottom of the tray 15 near both ends. The ends of the reinforcing rack 16 are fixedly installed on the side wall of the table 1.

[0033] An arched frame 17 is fixedly installed on the top of the tabletop 1. The arched frame 17 is located above the end of the adjustment hole 6 away from the center area of ​​the tabletop 1. A nozzle 18 is fixedly installed on the top of the arched frame 17, and the end of the nozzle 18 passes through the arched frame 17. The nozzle 18 is connected to an external air supply device. When the expansion head 9 completes one expansion operation and returns to the position near the end of the tabletop 1, the nozzle 18 can spray air to clean the outside of the expansion head 9.

[0034] A frame 19 is fixedly installed on the bottom side of the table 1 away from the adjustment hole 6.

A fixing block 21 is fixedly installed at the bottom of the transverse plate 3. The bottom of the fixing block 21 passes through the strip hole 23, and a threaded sleeve 22 is installed inside the fixing block 21. The threaded sleeve 22 is screwed to the outside of the lead screw 20. By rotating the lead screw 20, the lead screw 20 can drive the fixing block 21 to move through the threaded sleeve 22. As the fixing block 21 slides within the strip hole 23, the position of the transverse plate 3 can be adjusted, thereby changing the position of the top head 5 at the top of the transverse plate 3. This allows for adjustment of the distance between the top head 5 and the expansion head 9, which can be adapted to the length of the pipe under actual processing conditions.

[0035] The tabletop 1 also has symmetrical sliding holes 24 along the strip holes 23. A slider 25 is slidably installed in the sliding holes 24, and the top of the slider 25 is fixedly installed on the transverse plate 3. The slider 25 and the sliding holes 24 can improve the stability of the transverse plate 3.

[0036] One end of the lead screw 20 near the end of the tabletop 1 passes through the frame 19 and is coaxially connected to a rotating shaft 26. An adjustment handle 27 is fixedly installed at the end of the rotating shaft 26. Rotating the adjustment handle 27 will cause the lead screw 20 to rotate and be adjusted via the rotating shaft 26.

[0037] Through the above-described solution of this utility model, the structure of this utility model is simple and reasonable, and it is quick and convenient to use. By setting the transverse plate 3, the position of the top head 5 can be adjusted in the same way, so that the distance between the top head 5 and the expansion head 9 can be adjusted. It can be used for expansion operation of pipes of different lengths. After the expansion operation is completed, the expansion head 9 can be adjusted to converge. Then, the nozzle 18 installed on the arched frame 17 on the top of the table 1 is used for air blowing and cleaning operation to ensure the cleanliness of the surface of the expansion head 9 when expanding the pipe again, thereby improving product quality.
