s1, after starting up, the clamp springs ascend along the spiral track (18) and move forward in sequence and pass through the clamp spring screening blocking pieces (4), the clamp springs which are erected on the side are blocked by the clamp spring screening blocking pieces (4) and fall into the bottom of the conical hopper (20), and the clamp springs which are laid horizontally pass through smoothly; the snap springs falling into the bottom of the conical hopper (20) are queued again into the spiral track (18);
step S2, the clamp spring enters the linear feeding track (3) after coming out of the clamp spring feeding vibration disc and slides down, enters the first groove (321) from the feeding hole (323), the second photoelectric sensor (12) triggers an electric signal when sensing that the clamp spring is arranged below, and the following steps are sequentially delayed and executed:
s2.1, the push rod of the first electric push rod (33) pushes the clamp spring forwards to the intersection of the first groove (321) and the second groove (322), meanwhile, the push rod of the first electric push rod (33) seals the feed opening (323), and the subsequent clamp springs continue to wait in line in the linear feeding track (3);
s2.2, the clamp spring is pushed into the annular shallow groove (431) by a push rod of the second electric push rod (34), and then the push rod is retracted;
s2.3, vertically pressing the upper pressing plate (41) down by a push rod of a third electric push rod (42), and clamping the clamp spring together with the clamp spring pressing support table (43) up and down;
s2.4, a push rod of a fifth electric push rod (45) drives the telescopic shutter (6) to be folded forwards, so that the clamp spring pressing support table (43) drives the clamped clamp spring to be pushed to the position below a cutting blade of the cutting device (5) together;
s2.5, the cutting motor drives the cutting blade to rotate to cut the clamp spring, and the clamp spring falls down from the feed cutting opening (432) to feed so as to cut off one side of the clamp spring by half;
s2.6, the push rod of the fifth electric push rod (45) drives the telescopic shutter (6) to retreat to a half of the stroke and pause, the push rod of the third electric push rod (42) retracts to release the clamp spring, the push rod of the fourth electric push rod (44) pushes the clamp spring out of the clamp spring pressing support table (43) and falls into a discharge chute (19) below, and then the fourth electric push rod (44) retracts to the push rod;
s2.7, driving the telescopic shutter (6) to retreat backwards to the original position by a push rod of a fifth electric push rod (45), retracting the push rod of the first electric push rod (33) to the original position, enabling the next snap spring to enter the first groove (321) from the feed port (323), triggering the second photoelectric sensor (12) to generate an electric signal again, and circularly executing the steps S2.1-S2.7 to realize continuous production;
and S3, in the process of the step S2, when the jump ring lines backwards at the outlet of the linear feeding track (3) and exceeds the position of the first photoelectric sensor (14), the first photoelectric sensor (14) triggers induction and sends a signal to the jump ring feeding vibration disc, the jump ring feeding vibration disc stops feeding, and when the first photoelectric sensor (14) does not sense the jump ring below, the jump ring feeding vibration disc resumes feeding.
