A side gap adjustment mechanism for a rotary shear as defined in claim 3, wherein: the upper surface fixed connection of second processing platform (3) has fan filter equipment (34), two blast pipes (35) and two intake pipes (36) of positive fixedly connected with of fan filter equipment (34), and the one end at the back of two blast pipes (35) and two intake pipes (36) all is linked together with fan filter equipment (34), and the positive one end of two intake pipes (36) all is linked together with the back of collecting cover (37), it is located the below of first tool bit (22) to collect cover (37).
8. A side gap adjustment mechanism for a rotary shear as defined in claim 5, wherein: the upper surface of the first machining table (1) is provided with a sliding hole (38), the mounting rod (11) is connected in the sliding hole (38) in a sliding mode, and the shape of the sliding hole (38) is matched with that of the mounting rod (11).
A side clearance adjusting method of a circle shear side clearance adjusting mechanism is characterized by comprising the following steps:
s1, when the side clearance of the circle shear needs to be adjusted, a second motor (18) needs to be started, when the second motor (18) runs, a rotating shaft (12) is driven to rotate through a third driving wheel (14) and a fourth driving wheel (17), so that when the second motor (18) runs, a connecting roller (8) and a positioning sleeve (9) can rotate in a sliding groove (25), meanwhile, a second tool bit (23) can slowly get away from a first tool bit (22), after the second motor (18) is adjusted to a proper position, the second motor (18) can be closed, and as the mounting rod (11) can pull the fixing rod (28) to move in the rotating process, and synchronously drive a limiting block (31) to slide in a limiting groove (32), the effect of adjusting the side clearance of the circle shear is achieved;
s2, when the workpiece is machined and cut through the first cutter head (22) and the second cutter head (23), the first motor (4) and the third motor (19) need to be started, so that the first motor (4) and the third motor (19) respectively drive the first cutter head (22) and the second cutter head (23) to rapidly rotate through the first transmission wheel (5), the fifth transmission wheel (20), the first transmission belt (6) and the third transmission wheel (14) in the running process, the fan filtering device (34) is started simultaneously, so that cut impurities can directly fall in the collecting cover (37), and meanwhile, gas exhausted by the fan filtering device (34) can be sprayed on the surface of the first cutter head (22) after being filtered.
