In the such scheme, the assembly of loosing core on described is connected with die shank by hexagon socket head cap screw with the upper cores assembly, described die assembly down with under the assembly of loosing core be connected with the counterdie base by hexagon socket head cap screw.Adopt hexagon socket head cap screw to connect, be convenient to installation and removal, and can change different dies and loose core, realize that a die holder uses more.
In the such scheme, the assembly of loosing core on described comprise loose core and on the holder of loosing core, loose core on described holder will on loose core and be fixed on the die shank, on the holder of loosing core be connected with die shank by hexagon socket head cap screw.Described upper cores assembly comprises upper cores and upper cores fixed head, and described upper cores fixed head is fixed on upper cores on the die shank, and the upper cores fixed head is connected with die shank by hexagon socket head cap screw.Described die assembly down comprises the spacing die holder of die under the counterdie Renhe, and the spacing die holder restriction of described die down is the change in location of die down, and the spacing die holder of following die is connected with the counterdie base by hexagon socket head cap screw.Loose core under the assembly of loosing core under described comprises and under the holder of loosing core, the holder of loosing core under described will be loosed core down and will be fixed on the counterdie base, the holder of loosing core down is connected with the counterdie base by hexagon socket head cap screw.On loose core and under loose core and both play guide effect, can play product again and take out heart effect.On loose core holder, upper cores fixed head, the spacing die holder of die and the holder of loosing core down all belong to the restriction location structure down, can limit the position component of cooperation with it, and these parts can be changed flexibly.
In the such scheme, be provided with the concavo-convex guiding step that cooperatively interacts between described upper cores and the following die, concavo-convex guiding step cooperatively interacts, and realizes the effect of positioning and guiding.
In the such scheme, the described module of going up also includes the guide pin bushing of loosing core, and the guide pin bushing of loosing core on described is enclosed within the side of loosing core, and except playing the effect of positioning and guiding, can also play the end face position-limiting action and the material returned effect of product.
In the such scheme, described module down also comprises dish on screw rod, the spring, spring, spring lower wall, thimble, described screw rod is connected counterdie base below, spring is arranged on the screw rod, dish and spring lower wall are separately positioned on the two ends up and down of spring on the spring, described thimble passes the counterdie base, and two ends are withstood down on die and the spring and coiled.When module was closed up and down, following die was subjected to upper cores and presses down, by coiling on the pressing spring under the thimble, thus the compression spring.When the upper and lower mould component is opened, the spring elongation, dish rises on the spring, by thimble die is risen, and restores to the original state.
In the such scheme, described screw rod is provided with nut, and described nut is arranged on spring lower wall below.By adjusting nut can the regulating spring lower wall the position, thereby the intensity of regulating spring, die is pressed down with the ability of recovering can be adjusted as required.
Compared with prior art, the beneficial effects of the utility model are: 1, overall structure is simple, and is cheap and practical reliable; 2, adopt the close die design, avoid the common bad defective such as folding of common forge die, make the density of forging stronger; 3, can carry out dismounting and change, realize that a die holder uses more.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Structure of the present utility model comprises module and following module two large divisions as shown in Figure 1.Last module comprise die shank 1, on loose core 2, on loose core holder 3, first hexagon socket head cap screw 4, on loose core guide pin bushing 5, upper cores 6, upper cores fixed head 7 and second hexagon socket head cap screw 8.Following module comprises down die 9, looses core 10 down, thimble 11, down loose core holder 12, the 3rd hexagon socket head cap screw 13, the 4th hexagon socket head cap screw 14, coil 17 on the spacing die holder 15 of die, counterdie base 16, the spring down, spring 18, spring lower wall 19, nut 20 and screw rod 21.
On loose core 2 and on loose core holder 3 form the assembly of loosing core, be connected on the die shank 1 by first hexagon socket head cap screw 4.Upper cores 6 and upper cores fixed head 7 are formed the upper cores assembly, are connected on the die shank 1 by second hexagon socket head cap screw 8.On the guide pin bushing 5 of loosing core be enclosed within on 2 sides of loosing core, both played secondary guide effect, can play the end face position-limiting action of product again, can also play material returned effect.
Under loose core 10 and holder 12 compositions of loosing core down under the assembly of loosing core, be connected on the counterdie base 16 by the 3rd hexagon socket head cap screw 13.The spacing die holder 15 of following die 9 and following die is formed die assembly down, is connected on the counterdie base 16 by the 4th hexagon socket head cap screw 14.Screw rod 21 is connected counterdie base 16 belows, coils 17 on the spring, spring 18, spring lower wall 19 and nut 20 be installed on the screw rod 21 from top to bottom.Thimble 11 passes down loose core holder 12 and counterdie base 16, and two ends are withstood down respectively on die 9 and the spring and coiled 16 up and down.
During use, with die shank 1 pack into die shank hole and locking on the forging press, be placed on the forging press work top counterdie base 16 and locking, the parts of counterdie base 16 belows pass workbench as under the workbench.
The course of work of the present utility model is as follows:
Forging press upwards promotes and drives the patrix group to rising, when reaching top dead-centre, last module and following mould splits from, the bar after heating is put into down in the die cavity of die 9; Make forging press finish closed action by control button, upper cores 6 is pressed onto down on the die 9, following die 9 by under loose core 10 to lower slider; Thimble 11 is stressed to make on the spring distortion of exerting pressure of 17 pairs of springs 18 of dish to pressing down; After finishing the matched moulds forging and pressing, forge the machine slide block and return to top dead-centre, last module is return the original place; The elastic potential energy of spring 18 recovers to make down die 9 upwards to slide, and product is upwards driven.
By the adjusting nut 20 that makes progress, can make spring 18 strengthen decrements, it is withstood coil 17 on the spring, make thimble 11 withstand down die 9.Therefore can pass through regulating spring 18, the forging and pressing size of regulating product.Through disposable reciprocating motion, make the metal material plastic deformation under pressure, obtain the rolled-up stock of required size shape.This reciprocating motion circulation of passing through that does not stop like this operates, and the forging and pressing that product does not just stop are come out.
