The specific method of use is as follows:

[0030] Place the fuse to be trimmed and shaped horizontally on the positioning seat 2 in the left-right direction, so that the fuse body 71 is placed in the fuse body positioning groove 21, and the pair of pins 72 are correspondingly placed in the pair of pin placement grooves 22, and the pair of pins 72 are correspondingly passed through the pin positioning grooves 51 on the pair of parallel guide rails 5; at this time, the pair of cutters 3 are correspondingly located at the rear side of the pair of pins 72;

[0031] Then the first cylinder 42 drives the slide 41 to move forward, and the slide 41 drives the pair of cutters 3 to move forward, and the pair of cutters 3 move forward to contact the pair of pins 72 and cut the pair of pins 72 short, and the pair of cutters 3 continue to move forward until the pair of pins 72 are bent forward by 90 degrees, and the pair of pins 72 respectively form forward extension sections extending along the forward extension slot section 23; then the first cylinder 42 drives the slide 41 to move backward, and then drives the pair of cutters 3 to move backward and reset; the waste 73 of the pair of pins 72 cut by the pair of cutters 3 falls into the pair of waste collection slots 11 accordingly;

[0032] Then, a pair of second cylinders 63 extend toward each other, driving a pair of pin push rods 61 to approach each other, and the pair of pin push rods 61 push the forward extension sections of a pair of pins 72 to approach each other, so that the ends of the pair of pins 72 are bent into a hook shape, thereby completing the shear pin shaping of the fuse;

[0033] Then the pair of second cylinders 63 retract to drive the pair of pin push rods 61 to move away from each other and reset; then the fuse with the sheared pins shaped is taken away from the positioning seat 2.

[0034] As can be seen from the above, the fuse leg shearing and shaping jig of the utility model is used to implement leg shearing and shaping of the fuse, which can shorten a pair of pins 72 of the fuse and bend the ends of the pins 72 into a hook shape; and can improve the efficiency of fuse leg shearing and shaping, thereby improving the production capacity of the production line.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
