Compared with the prior art, the utility model discloses following beneficial effect has:

the special die is used for cutting the flying leads, so that the lengths of the flying leads reserved after the flying leads are cut by the same transformer are equal, and the lengths of the flying leads reserved after the flying leads are cut by the transformer cut by the die are kept constant. And one-time punching action can finish punching of all flying leads of one transformer, so that the flying lead pin cutting efficiency is improved.

In the above drawings: 1. carrying out top die; 2. bottom die; 3. accommodating grooves; 4. punching and cutting into blocks; 5. punching a through hole; 6. a positioning column; 7. A guide bar; 8. a compression plate; 9. a yielding groove; 10. a spring; 11. a nut; 12. aligning the column; 13. the holes are aligned.

Detailed Description

As shown in fig. 1, the embodiment of the utility model discloses planar transformer fly line pin cutter, including top mould 1 and die

block

2, 2 top surfaces of die block are opened there is holding tank 3 that holds the transformer, and 1 bottom surfaces of top mould are fixed with die-cut piece 4, die block 2 open have with die-cut through-hole 5 of 4 complex of die-cut piece. The edges of the punching block 4 and the punching through hole 5 form a shearing effect, the flying line extending into the range is cut off, and the sheared flying line is discharged along the punching through hole 5. And a positioning column 6 is fixed at the center of the accommodating groove 3 of the bottom die 2. The transformer is placed into the accommodating groove 3 and then abutted against the positioning column 6, so that all flying leads can just fall below the punching and cutting block 4, and the pin cutting operation can be completed at one time. At least three guide rods 7 are dispersedly fixed on the bottom surface of the top die 1, a compression plate 8 which is penetrated by each guide rod 7 and is parallel to the bottom surface of the top die 1 is connected on each guide rod 7 in a sliding way, and a abdicating groove 9 for accommodating a transformer is arranged at the position, which is over against the accommodating groove 3, of the bottom surface of the compression plate 8; the end part of the guide rod 7 is provided with a limiting block, so that the pressing plate 8 cannot be separated from the guide rod 7; a plurality of springs 10 are uniformly fixed between the pressing plate 8 and the top die 1, when the pressing plate 8 abuts against the limiting block and is farthest away from the top die 1, the springs 10 are still in a compressed state, and the bottom surface of the punching and cutting block 4 is higher than the bottom surface of the pressing plate 8 or is level with the bottom surface of the pressing plate 8. The spring 10 is always in a compression state, so that the compression plate 8 which is not pressed down is always parallel to the top die 1, the compression plate 8 and the bottom die 2 are more easily leveled and compressed on a flying line during pressing down, and shearing operation is facilitated.

Preferably, the guide rods 7 are screws, and a nut 11 is screwed on a section of each guide rod 7 between the top die 1 and the pressing plate 8. The nut 11 limits the displacement of the pressure plate 8 relative to the top die 1 during the push down blanking process, i.e. the maximum length of the blanking block 4 that can protrude beyond the pressure plate 8. And the nut 11 can be conveniently adjusted, so that when the edge of the punching and cutting block 4 becomes blunt after long-term use, the bottom surface of the punching and cutting block 4 can be polished, and the nut 11 is twisted to move upwards. In addition, the screw position of the bottom surface of the top die needs to be set to be a counter bore or the top surface of the bottom die is provided with a yielding hole corresponding to the screw position.

Preferably, at least two alignment columns 12 are fixed on the bottom surface of the top mold 1, and the bottom mold 2 is provided with alignment holes 13 matched with the alignment columns 12. The alignment column 12 and the alignment hole 13 are contacted in advance, so that the relative position of the punching block 4 and the punching through hole 5 before contact is adjusted, and the shearing edge is prevented from being damaged by staggered impact of the punching block and the punching through hole.

Preferably, the bottom end of the alignment post 12 is tapered or hemispherical. The alignment post 12 is conveniently extended into the alignment hole 13.
