Abstract
The utility model relates to a punching convex and concave die extraction tool for disassembly. The extraction tool comprises a die sleeve, a locking screw, an extraction gasket and an extraction screw; the die sleeve is in a cup-shaped structure with an opening on a head end, and the inner diameter thereof is bigger than the outer diameter of a punching convex die or a punching concave die; the wall of the die sleeve is provided with a radial screw hole penetrating the wall body, and the locking screw is assembled in the screw hole; and the tail end of the die sleeve is connected with the extraction screw, and the extraction screw is assembled with the extraction gasket for applying extraction force. The punching convex and concave die extraction tool has the advantages of simple and ingenious structure, convenient operation and strong adaptability; when the punching convex and concave dies are disassembled, the disassembly of a punching sub-die and knocking from the reverse die are not needed, the die sleeve in the tool only needs to be sleeved on the punching convex and concave dies and screwed by the locking screw, and the punching convex and concave dies can be conveniently extracted from a fixing plate.
Description
Technical field
The utility model belongs to the Stamping Die Technology field, relates to a kind ofly being used to dismantle that punching is protruding, the driver-extractor of die.
Background technology
At present, traditional pipe type 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 the pipe type heat exchanger, and air-conditioner fin generally adopts the 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 the limit, correcting, rip cutting, feeding and crosscut.The punching operation is to rely on the punching submodule to realize.The mechanism of punching submodule as shown in Figure 4, the punching submodule mainly comprises piercing punch 6 and the punching concave die 7 that cooperatively interacts, piercing punch 6 is assemblied in 9 li of punch retainers, punching concave die 7 is assemblied in 8 li of die blocks.Piercing punch 6 and punching concave die 7 are consumable accessorys, need the reconditioning cutting edge or change spare part after mould uses a period of time, dismantle more frequent.Because the gap between protruding, die of punching and the fixed head is very little, dismantle protruding, the die of punching, just must take the punching submodule come apart, with instrument that punching is protruding again, die is pounded out from the reverse side of fixed head, this method brings inconvenience for the assembling and setting personnel, also 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, provide a kind of punching of simple and ingenious structure protruding, the die driver-extractor, this driver-extractor can reduce assembly difficulty greatly, guarantees that mould can put into production as early as possible, improves the operating efficiency of daily maintenance.
The technical scheme that provides according to the utility model: a kind of punching is protruding, the die driver-extractor, it is characterized in that comprising die sleeve, lock-screw, rise and pull out pad and rise and pull out screw, described die sleeve is the cup-shaped structure of head end opening, and its internal diameter size is greater than the external diameter of piercing punch, punching concave die; Offer the screw radially that runs through wall body on the described die sleeve wall, lock-screw is assemblied in the screw; The tail end of described die sleeve has connected and has pulled out screw, rises to pull out to be fitted with on the screw to be used to apply rising of pulling force and to pull out pad.
As further improvement of the utility model, the lock-screw on the described die sleeve wall is at least two, and lock-screw circumference on the die sleeve wall evenly distributes.
The utility model compared with prior art, advantage is: simple and ingenious structure, easy to operate, applicability is strong; During protruding, the die of dismounting punching, need not to dismantle the punching submodule and knock from the negative, only need the die sleeve in the utility model is enclosed within that punching is protruding, on the die, utilizes lock-screw to tighten, can be easily that punching is protruding, die extracts from fixed head.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
Structure chart when Fig. 2 is used for piercing punch for the utility model.
Structure chart when Fig. 3 is used for punching concave die for the utility model.
Fig. 4 is the assembling schematic diagram of punching submodule.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 1: the utility model mainly by die sleeve 1, lock-screw 2, rise to pull out pad 3 and rise and pull out screw 4 and form, described die sleeve 1 is the cup-shaped structure of head end opening, its internal diameter size is greater than the external diameter of piercing punch 6, punching concave die 7; Offer the screw radially 5 that runs through wall body on described die sleeve 1 wall, lock-screw 2 is assemblied in the screw 5; Lock-screw 2 on described die sleeve 1 wall is at least two, and lock-screw 2 circumference on die sleeve 1 wall evenly distributes; The tail end of described die sleeve 1 has connected and has pulled out screw 4, rises to pull out to be fitted with on the screw 4 to be used to apply rising of pulling force and to pull out pad 3.
As Fig. 2, shown in Figure 3, during concrete the application, when needs dismounting piercing punch 6 or punching concave die 7, die sleeve in the utility model 1 is enclosed within on piercing punch 6 or the punching concave die 7, tightens lock-screw 2, make die sleeve 1 closely fixing with piercing punch 6 or punching concave die 7, pull out pad 3 and apply pulling force by rising then, thereby piercing punch 6, punching concave die 7 are extracted from punch retainer 9, die block 8 smoothly, need not to take apart again the punching submodule, improved the efficient of routine work greatly.
