After the hollow coil is placed, the positioning rod 11 is nested through the central hole, so that the positioning rod 11 overcomes the second elastic piece 13 and rotates and contracts backwards. The positioning rod 11 can position the hollow coil under the action of the second elastic member 13, so that the hollow coil keeps a middle position and the coil is prevented from being loosened. After the hollow coil is placed, the height of the bottom surface of the control rod 15 is adjusted according to the shapes of the hollow coil and the pressing surface 3, so that when the control rod 15 is in contact with the positioning seat 12, a gap of about 10mm is reserved between the pressing surface 3 of the upper template 1 and the positioning rod 11. After the control rod 15 is positioned, the bottom height of the adjusting nut 16 is adjusted according to the thickness of the hollow coil, and then when the upper template 1 is pressed in place, the upper end of the limiting plate 7 contacts the adjusting nut 16 and performs height limiting on the lifting frame 4.
When in pressing, the driving rod 5 above drives the lifting frame 4 to descend, so that the pressing surface 3 at the bottom of the lower die holder 2 moves downwards and presses the hollow coil; the central hole of the inner side of the hollow coil is changed along with the bending of the hollow coil to form a hole pattern in the pressing process of the hollow coil, and the positioning rod 11 is matched and rotated along with the hole pattern change of the central hole under the action of the second elastic piece 13 and keeps the extrusion limit on the inner circle of the hollow coil, so that the central limit and the pressing effect on the hollow coil are ensured, and the coil is prevented from being loose. When the lifting frame 4 moves to the control rod 15 and is attached to the positioning seat 12, a gap is reserved between the pressing surface 3 of the upper template 1 and the positioning rod 11 in the height direction, and the subsequent pressing of the lifting frame 4 drives the positioning seat 12 to move downwards together, so that the existence of the gap between the pressing surface 3 and the positioning rod 11 is ensured, and the rotation and tensioning stability of the positioning rod 11 is ensured. When the lifting frame 4 moves to the position that the limiting ring 6 contacts the laminating surface 3 of the lower die holder 2, the lower die holder 2 limits the height of the limiting plate 7 through the limiting ring 6, so that the limiting plate 7 slides relative to the lifting frame 4 along with the continuous pressing of the lifting frame 4 and the first elastic element 8 contracts; the height of the limiting plate 7 is kept unchanged, and the upper template 1 continues to be pressed downwards to press the hollow coil.
