Technological principle of the present invention is (be placed on patrix with the otch punch, the otch die is placed on counterdie to be come for example):
To finish the square shell of stretching by manipulator or other transmission devices and send into the otch station.This moment, the requirement to this operation was, the location core needs in the center of mould ` tool, guarantees the incision site precision of square casing with this.
Press slide begins descending, and it is descending to drive patrix, and when going downwards to certain position, the location core of center is inserted in the square casing, and it is descending together to drive square casing after the location core is entered in the square casing fully.
Patrix is equipped with several bars of beating, the bottom of making bar has more certain distance than the bottom of otch punch and (is generally 0.02~0.05mm, this is designed to edge of a knife gap, otch wall portion thickness difference as required, clearance height is also inequality), continue go downwards to location core when fully entering into otch die in when patrix this moment, and making bar and can beating and contact the otch die of patrix just begins to enter at this moment the otch process.
After this patrix continue descending, the making bar and can continue to press down the otch die of patrix, because otch die and guide runner are fixed together, thereby guide runner can be followed with the otch die and moved downward together.
