Preferably, elastic members 353 are connected between each crimping wheel 352 and the limiting driver 351 in a one-to-one correspondence, so that flexible pressing can be realized through each elastic member 353. In addition, during the collapsing process, the effect of the rotation force applied to the heat pipe 200 with a certain length is gradually reduced from the large end 201 close to the collapsing die head 32 to the small end 202 far from the collapsing die head 32, and therefore, each of the pressure wheels 352 is further correspondingly connected with a spring damper 354, so that the pressure exerted by each pressure wheel 352 is correspondingly adjusted through each spring damper 354, that is, the pressure force applied to the pressure wheel 352 closest to the collapsing die head 32 is the largest, and the pressure force applied to the pressure wheel 352 farthest from the collapsing die head 32 is the smallest, thereby providing more accurate pressure.

after the equipment is started, when a sensor arranged at the feeding position 11a of the conveying guide rail 11 senses the fed material, a signal is sent to the controller, under the indication of the controller, the positioning jig 12 fully loaded with the radiating pipes 200 is conveyed by the feeding position 11a of the conveying guide rail 11 and positioned at the position of the feeding position 11b, when the sensor positioned at the position senses the positioning jig 12, a signal is sent to the controller, under the indication of the controller, the feeding device 20 acts to reciprocate between the conveying guide rail 11 and the tail reducing device 30, and 2 radiating pipes 200 are correspondingly transferred to two bearing units 33a arranged on the bearing table 333 each time;

then, under the instruction of the controller, the positioning carrier 33 linearly reciprocates along the Y-axis direction, so as to alternately reciprocate between the thermal tail die head 31 and the two pairs of positioning mechanisms 22 on both sides thereof, first, the two positioning seats 332 and the two pairs of positioning mechanisms 22, which are arranged in one-to-one correspondence, are matched to position and align the two heat dissipation tubes 200 carried on the two carrying units 33a, so that the distance between the pipe orifices of the large ends of the two heat dissipation tubes 200 and the thermal tail ports 32a is adjusted to a preset distance, then, the limiting mechanism 35 linearly reciprocates along the Z-axis direction, so as to move from the upper side to abut against the heat dissipation tubes 200 opposite to the thermal tail die head 32, then, the thermal tail die head 32 linearly moves along the X-axis direction again, so as to approach the heat dissipation tubes 200 opposite thereto, so that the pipe orifices of the large ends 201 of the heat dissipation tubes 200 are inserted into the thermal tail ports 32a of the thermal tail die head 325, and during the plugging process, the rotating cutter in the thermal tail head 325 correspondingly retracts the thermal tail ends 201 of the thermal tail tubes 200, to form a tapered constriction;
