Abstract

The invention relates to an extraction tool for a punching male die or a punching female die. The extraction tool comprises a die sleeve, extraction pieces and an extraction bolt. The die sleeve is of an cup-shaped structure with an opening in the head end, two or more extraction pieces are hinged in the opening in the head end of the die sleeve, a clamping block is arranged at the head end of each extraction piece, the extraction bolt is connected to the tail end portion of the sleeve die in a threaded mode, an inclined wedge through hole radially penetrating through the wall body of the sleeve die is formed in the head end of the sleeve die, an inclined wedge capable of enabling the extraction pieces to be opened or closed is slidingly connected in the inclined wedge through hole in an inserted mode, and a locking screw capable of enabling the inclined wedge to be positioned is arranged on the inclined wedge. The extraction tool for the punching male die or the punching female die is simple and exquisite in structure, easy to operate and strong in applicability; when the punching male die and the punching female die are dismounted, the sleeve die only needs to be arranged on the punching male die and the punching female die in a sleeved mode instead of knocking the punching male die and the punching female die from the backside by a dismounting punching sub die, the locking screw screws the positioning inclined wedge, and then the punching male die and the punching female die can be pulled out of a fixing board conveniently.

Description

The driver-extractor of piercing punch or punching concave die
Technical field
The invention belongs to Stamping Die Technology field, the driver-extractor of especially a kind of piercing punch of the present invention or punching concave die.
Background technology
At present, traditional Gilled heat exchanger is the main heat exchange form of domestic air conditioning, central air-conditioning, car air-conditioner and fan coil.Air-conditioner fin is the vitals in Gilled heat exchanger, and air-conditioner fin generally adopts air-conditioner fin die punching press to make, and its production process generally comprises and extends, punching, shutter, flange, abnormal shape are cut, cut on limit, correcting, rip cutting, feeding and crosscut.Punching operation is to rely on piercing die to realize.Piercing die mainly comprises piercing punch and the punching concave die cooperatively interacting, and piercing punch is assemblied in punch retainer, and punching concave die is assemblied in die block.Piercing punch and punching concave die are consumable accessorys, need reconditioning cutting edge or change spare part after mould is used a period of time, dismantle more frequent.Because gap between punching punch and matrix and fixed head is very little, dismantle punching punch and matrix, just piercing die must be taken apart, with instrument, punching punch and matrix is pounded out from the reverse side of fixed head again, this method is brought inconvenience to assembling and setting personnel, also relatively lose time, have a strong impact on daily production efficiency.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and can greatly reduce the dismounting difficulty of piercing punch or punching concave die, the piercing punch of operating efficiency or the driver-extractor of punching concave die of raising ordinary maintenance maintenance.
According to technical scheme provided by the invention; the driver-extractor of described piercing punch or punching concave die; it comprises die sleeve, plectrum and rises and pull out screw; described die sleeve is the cup type structure of head end opening; in the head end opening of die sleeve, be hinged with more than two or two plectrums; head end at every plectrum is provided with fixture block; at the tail end of die sleeve, be bolted with and pulled out screw; on the head end of die sleeve, offer the wedge through hole that radially runs through its wall body; in wedge through hole, sliding plug has the wedge that can make plectrum folding, is provided with the lock-screw that can make wedge location on wedge.
Be fixed with and pulled out pad rising to pull out on screw.
Simple and ingenious structure of the present invention, simple to operate, applicability is strong; During dismounting punching punch and matrix, without dismounting piercing die, knock from the negative, only the die sleeve in the present invention need be enclosed within on punching punch and matrix, utilize lock-screw screwed in place wedge, can easily punching punch and matrix be extracted from fixed head.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with specific embodiment, the invention will be further described.
The driver-extractor of this piercing punch or punching concave die; it comprises die sleeve 1, plectrum 2 and rises and pull out screw 3; the cup type structure that described die sleeve 1 is head end opening; in the head end opening of die sleeve 1, be hinged with more than two or two plectrums 2; head end at every plectrum 2 is provided with fixture block 4; at the tail end of die sleeve 1, be bolted with and pulled out screw 3; on the head end of die sleeve 1, offer the wedge through hole 5 that radially runs through its wall body; in the interior sliding plug of wedge through hole 5, there is the wedge 6 that can make plectrum 2 foldings, on wedge 6, be provided with the lock-screw that can make wedge 6 location.
Be fixed with and pulled out pad 7 rising to pull out on screw 3.
During concrete application; when needs are dismantled piercing punch or punching concave die; die sleeve in the present invention 1 is enclosed within piercing punch or punching concave die; from the interior insertion wedge 6 of wedge through hole 5; wedge 6 opens plectrum 2; make the fixture block 4 of plectrum 2 head ends closely fixing with piercing punch or punching concave die; then by lock-screw, wedge 6 is located; by rising, pull out pad 7 and apply pulling force; thereby piercing punch or punching concave die are extracted smoothly from punch retainer or die block; need not take again piercing die apart, greatly improve the efficiency of routine work.
