Abstract
The utility model relates to an extraction tool for a hole punching male die or a hole punching female die. The extraction tool comprises a die sleeve, extracting pieces and an extracting screw. The die sleeve is of a cup-shaped structure with the head end open. Two or more extracting pieces are hinged into the opening of the head end of the die sleeve. A clamping block is arranged at the head end of each extracting piece. The extracting screw is connected to the tail end of the die sleeve in a screwed mode. An inclined wedge through hole which penetrates through the wall body of the die sleeve in the radial direction is formed in the head end of the die sleeve. An inclined wedge which allows the extracting pieces to be opened and closed is inserted and connected into the inclined wedge through hole in a sliding mode. A locking screw which can position the inclined wedge is arranged on the inclined wedge. The extraction tool is simple and ingenious in structure, easy to operate and high in applicability; when detaching the hole punching male die or the hole punching female die, a user does not need to detach a hole punching sub-die or to knock on the rear face and only needs to enable the hole punching male die or the hole punching female die to be sleeved with the die sleeve of the extraction tool and screw down and position the inclined wedge through the locking screw, and therefore the hole punching male die or the hole punching female die can be conveniently extracted from a fixing plate.
Description
Technical field
The utility model belongs to Stamping Die Technology field, the driver-extractor of especially a kind of piercing punch of the utility model 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 purpose of this utility model is to overcome the deficiencies in the prior art, provides 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.
The technical scheme providing according to the utility model; 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.
The utility model simple and ingenious structure, 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 utility model 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 utility model.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
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 utility model 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.
