The pushing frame 17 is slidingly connected to the inner wall of the cylinder 12. A fixed frame 21 is connected to the right side of the cylinder 12, and a pushing plate 22 is slidingly connected to the left side of the screw 16. The pushing plate 22 slides with the fixed frame 21. A second spring 23 is connected between the pushing plate 22 and the pushing frame 17, and the second spring 23 is sleeved on the screw rod 16. A clamping assembly for clamping the inner liner pipe is provided in the cylinder 12, and a flanging assembly is provided on the left side of the top of the base 1.

[0023] like Figure 1 、 Figure 3 and Figure 4 As shown, the clamping assembly includes a clamping frame 18, an inclined block 19 and a first spring 20. Three clamping frames 18 for clamping the liner tube are slidably connected along the inner wall of the cylinder 12. The clamping frame 18 is located on the inner side of the fixed frame 21 and the pushing frame 17. The left end of the clamping frame 18 extends out of the left port of the cylinder 12. Multiple first springs 20 are connected between the clamping frame 18 and the inner wall of the cylinder 12. The right side of the clamping frame 18 is integrally connected with an inclined block 19, and the pushing frame 17 is in contact with the inclined block 19.

[0024] like Figure 1 and Figure 2 As shown, the flanging assembly includes a first motor 2, a first electric slide rail 3, a first slider 4, a pressure head 5 and a heating assembly. The first motor 2 is installed on the left side of the top of the base 1 by bolts, the first motor 2 is connected to the output shaft of the first motor 2, the first slider 4 is slidingly connected to the first electric slide rail 3, the top of the first slider 4 is connected to the pressure head 5 for flanging the inner liner pipe port, and a heating assembly is provided on the left front side of the top of the base 1.

[0025] like Figure 1 and Figure 2 As shown, the heating assembly includes a third electric slide rail 10, a third slider 101 and a heating wire 11. A third electric slide rail 10 is installed on the left front side of the top of the base 1 by bolts. The third slider 101 is slidably connected to the third electric slide rail 10. A third electric slide rail 10 is also installed on the third slider 101 by bolts. The third electric slide rail 10 on the upper side is also slidably connected to the third slider 101. The third slider 101 on the upper side is slidably connected to the heating wire 11 for heating the port of the liner pipe. The heating wire 11 is annular and fits the shape of the pipe mouth of the liner pipe.

[0026] like Figure 1 and Figure 2 As shown, it also includes an electric push rod 6, a discharge frame 7, a second electric slide rail 8 and a second slider 9. The electric push rod 6 is installed on the outer shell of the first electric slide rail 3 by bolts. The discharge frame 7 for placing the inner liner is connected to the telescopic rod of the electric push rod 6. The discharge frame 7 is aligned with the left end of the cylinder 12. The discharge frame 7 is semicircular and fits the shape of the inner liner. The second electric slide rails 8 are symmetrically installed on the discharge frame 7. The second slider 9 for pushing the inner liner is slidably connected between the two second electric slide rails 8. The second slider 9 is slidably connected to the inside of the discharge frame 7.

[0027] When flanging the liner tube, first place the liner tube in the discharge frame 7, then start the second electric slide rail 8, the second electric slide rail 8 drives the second slider 9 to move to the right, and pushes the liner tube to the right through the second slider 9 until the liner tube is pushed into the cylinder 12. After that, the second electric slide rail 8 drives the second slider 9 to return to the initial position on the left, and then start the electric push rod 6 to retract its telescopic rod, driving the discharge frame 7 and the components thereon to descend to ensure that there will be no interference with subsequent operations. When the electric push rod 6 completes the action and closes, the cylinder 13 is started, and the telescopic rod of the cylinder 13 extends to drive the stop rod 14 to move downward to the preset position. At this time, the cylinder 13 stops operating, and then the second motor 15 is started. The output shaft of the second motor 15 starts to rotate and drives the screw 16 to rotate. The rotation of the screw 16 prompts the pushing frame 17 to move to the left. The pushing frame 17 pushes the pushing plate 22 to move to the left through the second spring 23 until the pushing plate 22 contacts the inner liner and pushes it to the left. When the left port of the inner liner contacts the stop rod 14, the pushing frame 17 continues to move to the left, causing the second spring 23 to be compressed. When the pushing frame 17 contacts the inclined block 19, the inclined block 19 and the clamping frame 18 will be pushed by the pushing frame 17 moves inward, and at the same time the first spring 20 will be stretched, and the clamping frame 18 clamps the inner lining tube in the center. After this step is completed, the second motor 15 stops running, and then controls the two third electric slides 10. The third electric slide 10 on the lower side can drive the third slider 101 on the lower side to move left or right, and then drive the third electric slide 10 on the upper side, the third slider 101 on the upper side and the heating wire 11 to move synchronously. When the third electric slide 10 on the upper side is started, it can drive the third slider 101 on the upper side and the heating wire 11 to move forward or backward. In this way, the two third electric slides 10 can be controlled according to the position of the inner lining tube, so that the heating wire 11 is sleeved on the left port of the inner lining tube to heat it. After the end of the inner liner tube is softened, the heating wire 11 is controlled to return to its original position, and then the first electric slide rail 3 is started, which drives the first slider 4 and the pressure head 5 to move forward so that the pressure head 5 contacts the end of the inner liner tube. Then the first motor 2 is started, and the output shaft of the first motor 2 rotates to drive the first electric slide rail 3 to rotate, and then drives the first slider 4 and the pressure head 5 to rotate, so as to realize the flanging operation of the softened end of the inner liner tube. After the flanging is completed, the first motor 2 runs in the reverse direction, driving the first electric slide rail 3, the first slider 4 and the pressure head 5 to rotate in the reverse direction and reset, and also drives the electric push rod 6 and the discharge frame 7 to reset.This completes the flanging operation of an inner liner tube, after which the various components need to be reset: the first electric slide rail 3 drives the first slider 4 and the pressure head 5 to move backward and return to their original positions; the electric push rod 6 is controlled to extend the telescopic rod to return the material discharging frame 7 to its original position; the second motor 15 is controlled to run in the opposite direction, driving the screw 16 to reverse, so that the push frame 17 moves to the right and resets, the second spring 23 gradually recovers, and the push plate 22 also moves to the right and resets. After the push frame 17 is reset and disengaged from the bevel block 19, the first spring 20 recovers, so that the clamping frame 18 and the bevel block 19 move outward and reset, thereby releasing the inner liner tube. At this point, the processed inner liner tube can be taken out, and the flanging process of other inner liner tubes can be continued according to the above steps. Finally, all related equipment is turned off after the work is completed.
