The working principle of the invention is as follows:

s1, front bending of the middle pin: a triode to be subjected to pin shearing is horizontally placed on the top surface of the bottom plate 1, then a left pin 26, a middle pin 27 and a right pin 28 of the triode are respectively and simultaneously inserted into the first clamping groove 6, the second clamping groove 7 and the third clamping groove 8 from back to front, and at the moment, a main body part 25 of the triode is positioned in the groove 5 as shown in fig. 6; when the main body part 25 is pushed forwards, the middle pin 27 penetrates out of the second clamping groove 7 and then is completely deformed upwards along the arc-shaped surface 10, so that the middle pin is quickly bent and formed without manually adopting a pair of pliers completely, and the labor intensity of workers is reduced;

s2, cutting of the left pin: a worker controls a piston rod of a longitudinal oil cylinder 13 of the left pin shearing mechanism 3 to extend out, the piston rod drives a sliding block 17 to move backwards along a guide rail 16 through a connecting plate 18, when a cutter 15 is opposite to a left cushion block 11, as shown in fig. 6, the worker controls the longitudinal oil cylinder 13 of the left pin shearing mechanism 3 to be closed, simultaneously controls a piston rod of a horizontal oil cylinder 14 to extend out, and the cutter 15 moves rightwards to cut off a left pin 26 of a triode;

s3, cutting of right pins: a worker controls a piston rod of a longitudinal oil cylinder 13 of the right pin shearing mechanism 4 to extend out, the piston rod drives a sliding block 17 to move backwards along a guide rail 16 through a connecting plate 18, when a cutter 15 is opposite to a right cushion block 12, as shown in fig. 6, the worker controls the longitudinal oil cylinder 13 of the right pin shearing mechanism 4 to be closed, simultaneously controls a piston rod of a horizontal oil cylinder 14 to extend out, and the cutter 15 moves leftwards to cut off a right pin 28 of a triode;

s4, after the triode pin is cut and formed, a worker turns on the air compressor 19, the air compressor 19 generates high-pressure gas, the high-pressure gas enters the inclined hole 20 through the pipeline 21, and the high-pressure gas sprayed out of the inclined hole 20 blows the finished triode backwards, so that the finished triode is rapidly discharged.

Therefore, the foot shearing machine realizes the rapid shearing of the left pin 26 and the right pin 28 by controlling the action of the cutter, ensures the smoothness of the cut, and does not need to be operated by a pair of cutting pliers manually, thereby reducing the labor intensity of workers and improving the production efficiency; in addition, the middle pin 27 is directly bent and formed through the arc-shaped surface 10 of the forming seat 9, a worker does not need to hold a pliers to bend, the labor intensity of the worker is further reduced, and the production efficiency is improved.
