6. The quartz tube expanding process includes the following steps:
s1: firstly, an operator firstly places a quartz tube of a tube to be expanded on a device, then operates a heating device (13), at the moment, the quartz tube is heated by the operation of the heating device (13), at the moment, due to the temperature rise, the gas of a T-shaped clamping block (16) close to the inner cavity of a base (1) at one side of a tension spring (17) expands, the T-shaped clamping block (16) moves to one side far away from the tension spring (17), at the moment, the inclined clamping block (15) moves downwards through the cooperation between the T-shaped clamping block (16) and the inclined clamping block (15), so that the inclined clamping block (15) is separated from the inner cavity of a clamping groove (19), the clamping between a sleeve rod (5) and the inclined clamping block (15) is released, and meanwhile, the quartz tube is preheated, so that the subsequent device is convenient for expanding the quartz tube;
s2: simultaneously, due to the elastic force of the elastic spring (6), the sleeve rod (5) moves to one side close to the second connecting rod (8), at the moment, the first connecting rod (7) and the second connecting rod (8) respectively rotate clockwise and anticlockwise, so that the arc-shaped sleeve rod (9) and the rolling shaft (10) are jacked up, the rolling shaft (10) is further in contact with the inner wall of the quartz tube, then an operator operates the power motor (3) to enable the main shaft rod (4) to drive the sleeve rod (5) to rotate, and further the first connecting rod (7) and the second connecting rod (8) drive the arc-shaped sleeve rod (9) and the rolling shaft (10) to rotate in the inner wall of the heated quartz tube, and meanwhile, due to the limitation of the half-arc limiting block (12), when the rolling shaft (10) extrudes the quartz tube, the outer wall of the quartz tube is enabled to be in contact with the inner wall of the half-arc limiting block (12), the tube expanding operation of the quartz tube is completed at the moment;
s3: after the quartz tube expansion is completed, an operator stops operating the power motor (3) and the heating device (13) at the moment, then operates the power motor (22) to enable the bidirectional threaded rod (23) to rotate, so that the circular ring block (24) moves outwards, and at the moment, the half-arc limiting block (12) moves outwards through the cooperation limiting effect between the second supporting frame (20) and the second limiting rod (21) and between the cylindrical rod (26) and the sliding groove (27), so that the quartz tube inside the half-arc limiting block (12) is exposed, and then people move the quartz tube to the side far away from the power motor (3), so that the quartz tube is taken out.
