First cutting: opening the equipment, wherein the gold pin conveying clamp 2 is positioned at a left dead center, and the control device controls the clamp part of the gold pin conveying clamp 2 to be closed so as to fix the gold pin; meanwhile, the control device controls the gold pin fixing clamp 1 and the gold pin cutting device 3 to be still in an open state;

as shown in fig. 5, the control device controls the reciprocating driving device of the gold pin conveying clamp 2 to start to operate, so that the clamp part of the gold pin conveying clamp 2 moves to the gold pin cutter 3, and the gold pin is driven by the gold pin conveying clamp 2 to move to the gold pin cutter 3 to enable the front end of the gold pin to extend forwards because the clamps of the gold pin fixing clamp 1 and the gold pin cutter 3 are in an open state at the moment; when the control device detects that the gold pin conveying clamp 2 moves to the right dead center position through the position sensor, the control device controls the clamp part of the gold pin conveying clamp 2 to be opened; meanwhile, the control device controls the gold pin fixing clamp 1 and the gold pin cutting device 3 to be closed, and the front end and the rear end of the gold pin are fixed.

After the gold pin is fixed, the control device controls a cutting unit of the gold pin cutting device 3 to perform cutting operation, so that the gold pin extending out of the knife edge can be cut off; meanwhile, the control device controls the clamp part of the gold pin conveying clamp 2 to be opened, and controls the reciprocating driving device of the gold pin conveying clamp 2 to drive the clamp part to the left, so that the opened clamp part moves to the left until reaching a left dead center; thereby completing the first cut.

And (3) cutting for the second time: after the clamp portion of the gold pin conveyance clamp 2 reaches the left dead center, the second cutting is started: the control device controls the clamp part of the gold pin conveying clamp 2 to close again to fix the gold pin; the control device controls the gold pin fixing clamp 1 and the gold pin cutter 3 to be in an open state again; the gold pin is driven by the gold pin conveying clamp 2 to move towards the gold pin cutting device 3, so that the front end of the gold pin extends forwards; when the gold pin transfer jig 2 moves to the right dead center position, the control device controls the jig portion of the gold pin transfer jig 2 to open; and the control device controls the gold pin fixing clamp 1 and the gold pin cutting device 3 to close, and fixes the front end and the rear end of the gold pin.

After the gold pin is fixed, the control device controls a cutting unit of the gold pin cutting device 3 to perform cutting operation, so that the gold pin extending out of the knife edge can be cut off; meanwhile, the clamp part of the gold pin conveying clamp 2 is opened, and the clamp part moves leftwards until reaching a left dead point under the drive of a reciprocating driving device of the gold pin conveying clamp 2; thereby completing the second cut. The process is repeated, so that the cutting-off of the gold pins can be automatically operated.

As shown in fig. 7, the gold pin transfer jig 2 includes: a guide rail 21 is arranged on the bedplate 4, and a clamp for fixing a gold pin is arranged on the guide rail in a sliding way; the clamp part is the same as the part of the gold pin fixing clamp 1, and is not described again here. The lower surface of the clamp is provided with a sliding groove matched with the guide rail 21. The reciprocating driving device is used for driving the clamp to slide on the guide rail in a reciprocating manner; the form of the reciprocating driving device can be selected according to the needs, for example, an electric push rod is selected to push and pull the clamp part of the gold pin conveying clamp 2, or a crank is driven by a motor to rotate and is connected with the clamp part of the gold pin conveying clamp 2 through a connecting rod to form a crank block structure, so that the clamp part of the gold pin conveying clamp 2 slides on the guide rail in a reciprocating mode.
