Example (b):

as shown in fig. 1-4, the utility model provides a radiator tube expander, including base 1 with set up in base 1 and along sharp first positioning seat 2, second positioning seat 3, guide holder 4 and the driving piece 5 that distributes in proper order. A placing gap for placing the radiator 8 is arranged between the first positioning seat 2 and the second positioning seat 3. The guide base 4 is slidably provided with a slide plate 41. In particular, the guide 4 comprises a cover plate 42. The cover plate 42 is disposed above the base 1 and connected to the base 1 by a connector. So that a gap through which the sliding plate 41 passes is formed between the cover plate 42 and the base 1. The slide plate 41 is provided with slide blocks 43 on opposite sides thereof for engaging with the base 1 and the cover plate 42, respectively. The slider 43 is dovetail shaped. The base 1 and the cover plate 42 are provided with dovetail-shaped sliding grooves 44 in cooperation with the sliding blocks 43. The cooperation of the slide block 43 and the slide groove 44 enables the slide plate 41 to stably slide between the cover plate 42 and the base 1. Meanwhile, the cover plate 42 can also play a role in protecting a human body from contacting moving parts such as the sliding plate 41.

One side of the sliding plate 41 is connected with the driving piece 5, and the other end is connected with a plurality of tube expanding rods 6. The second positioning socket 3 is provided with a through hole 31 in cooperation with each expansion rod 6, so that the expansion rod 6 can pass through the through hole 31 and extend to the inside of the base pipe 81 of the radiator 8. The driving member 5 may be a pneumatic cylinder or a hydraulic cylinder.

The utility model discloses a when radiator electric tube expander used, earlier locate a plurality of parent tubes 81 with a plurality of fin 82 covers for it makes up with parent tube 81 to go out the piece. The combined basepipes 81 and fins 82 are then placed in the placement gap with one end of each basepipe 81 aligned with one of the pass-through holes 31. The driving member 5 is actuated so that the plurality of expansion rods 6 each extend into the interior of one of the base pipes 81 and move forward along the base pipe 81. The expansion rod 6 moves from one end of the base pipe 81 to the other due to the blockage of the first positioning seat 2. The base tube 81 is expanded by the tube expansion rod 6 in the process of passing through the base tube 81, so that the outer wall of the expanded base tube 81 is tightly attached to the hole wall of the fin 82, and the fin 82 and the base tube 81 are stably connected. Subsequently, the driver 5 pulls the expansion rod 6 to retract, thereby disengaging the expansion rod 6 from the base pipe 81.

In this embodiment, the end of the tube expansion rod 6 away from the sliding plate 41 is provided with a tube expansion head 61. The outer diameter of the tube expanding head 61 is larger than that of the tube expanding rod 6. The base pipe 81 can be expanded by the base pipe head 61 through the base pipe 81. One end of the tube expanding head 61, which is far away from the tube expanding rod 6, is conical, and one end of the tube expanding rod 6, which is far away from the tube expanding head 61, is a smaller end. This allows the expansion head 61 to be easily inserted into the base pipe 81, thereby expanding the base pipe 81.

In this embodiment, a set of positioning holes 11 is disposed on both sides of the base 1. The plurality of positioning holes 11 in each group are distributed along a straight line, and the straight line where the plurality of positioning holes 11 in each group are located is parallel to the connecting line of the second positioning seat 3 and the guide seat 4. Both sides of the second positioning seat 3 are provided with connecting holes 32 matching with the positioning holes 11. The second positioning seat 3 and the base 1 can be fixed by inserting bolts after the connecting holes 32 are butted with the positioning holes 11. This arrangement allows the fixing position of the second positioning seat 3 relative to the base 1 to be adjusted as required, thereby adapting to radiators 8 with different sizes.

In this embodiment, a positioning mold 7 is further included. Placing gaps 71 are formed in the two ends of the positioning mold 7 in a manner of being matched with the base pipes 81, so that when the radiator 8 is placed in the positioning mold 7, the two ends of each base pipe 81 are respectively accommodated in one placing gap 71. Thereby positioning the heat spreader 8 with respect to the positioning die 7. And placing the positioning mold 7 into the placing gap after the radiator 8 is placed in the positioning mold 7. Through positioning die 7 can be quick place radiator 8 in placing the clearance and fix a position, improve production efficiency.

In this embodiment, two adjusting screws 12 are further disposed on one side of the base 1. Specifically, the side of the base 1 is provided with a mounting seat 13. The mounting seat 13 protrudes from the surface of the base 1. The adjusting screw 12 is screwed in the mounting base 13 and one end of the adjusting screw 12 horizontally extends into the placing gap. The positioning die 7 is placed in the placing gap process, and the positioning die 7 is pushed to be tightly against the adjusting screw 12, so that rapid positioning is realized. The arrangement of the adjusting screws 12 can adjust the placing position of the positioning mould 7, so that the heat radiator 8 can be adapted to various types. The adjusting screw 12 is also provided with a set nut 14. After the positioning nut 14 is screwed on the mounting seat 13, the position of the adjusting screw 12 relative to the mounting seat 13 can be fixed, and the adjusting screw 12 is prevented from loosening.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
