Really connection positioning mold.Since drive system is heavier, inconvenient movement and adjustment, riding position is usually disposably determined, is led to
It is obviously more suitable to be directed at sizing die and drive system to cross promotion sizing die.It is slidedly arranged on mold changing slot in order to smooth, it is different
The width of support plate is corresponding with mold changing slot, and length specification can be not exactly the same, i.e., at the fixation position for determining sizing die
It need to only determine the position of sizing die length direction on mold changing slot, therefore the fixation member need to be set.In addition, in order to improve
Alignment precision, the distance between two pieces of transverse plates 222 are greater than the width of fixing groove 38 ", are finely tuned by setting location nut 223
The position of sizing die.Positioning element is detachably connected sizing die, and convenient for the production and processing of sizing die, fixed plate 21 is removable
The connection sizing die and sizing mill unloaded will not interfere the mobile generation of sizing die, two fixed jaws of fixed plate 21 that
This hinged setting, convenient for the storage of fixed plate 21.
The front end of upper table surface 31 " is equipped with switch cover 311 ", close switch 312 ", post-positioning block 313 " and hydraulic bjuffer
314".The nearly rear end of mold changing slot two sides is also respectively provided with a bolt 315 ", two bolts 315 " removably insert in upper table surface
In 31 " jack.When there is sizing die on upper table surface 31 ", bolt 315 " is inserted into jack, is stopped on upper table surface 31 "
Sizing die slides out upper table surface 31 ", when sizing die will enter upper table surface 31 " or exit upper table surface 31 ", extracts from jack
Bolt 315 " releases the blocking of bolt 315 ".The nearly rear end of two cam installation groups is respectively fixed with a hanger pin 316 ".
Bottom plate 32 " is equipped with the through-hole through bottom plate 32 ", and the oil cylinder that the through-hole of the bottom plate 32 " is located at drive system connects
First 241 " surface, after sizing die is located at upper table surface 31 " and fixes, cylinder connector 241 " contacts and connects with sizing die
It connects.
Transfer device is as shown in figure 9, include the interface 51 " for being located at same level with upper table surface 31 ", interface 51 "
It is used to support sizing die, interface 51 " is equipped with die cavity, and die cavity is along lowland in one side of interface 51 " through rank out
The plate face of junction 51 " forms character cut in bas-relief shape.The mold changing groove width of the width of die cavity and upper table surface 31 " is equal out, out the two of die cavity
Side is respectively provided with two rows of steel ball idler wheels 35 ", and multiple steel ball idler wheels 35 " of every row are evenly distributed, the arrangement side of every row's steel ball idler wheel 35 "
To parallel with the length direction of die cavity out.Transfer device is removable, and the bottom of transfer device is equipped with brake wheel and fast pulley, is used for
Mobile and fixed transfer device.The depanning channel opening end two sides of transfer device are respectively fixed with a hook, two each hookings of hook
One hanger pin 316 ".The opening splicing that transfer device is moved to out the opening of die cavity and upper table surface 31 " changes the mold slot is pushed to close up,
At this point, the steel ball idler wheel 35 " of die cavity two sides is located at the extended line that upper table surface 31 " changes the mold the steel ball idler wheel 35 " of slot two sides out
On, by two each one hanger pins 316 " of hooking of hook, fast pulley is closed, then transfer device is fixedly connected with die changing mechanism.Turn
Shipping unit is used to replace the sizing die on upper table surface 31 ", and the opening of die cavity and upper table surface 31 " change the mold the opening splicing of slot simultaneously out
Hold together, and after fixed transfer device, the sizing die on upper table surface 31 " is made to be moved to transhipment dress along the mold changing slot and out die cavity
The interface 51 " set, or the sizing die on the interface 51 " of transfer device is moved to upper table surface 31 ".
To sum up, when carrying out pipe fitting processing, for expanding technique and throat processing method, identical mark can be shared
Quasi- supporting mechanism and sizing system, only need to change sizing component.And for the processing technology of the whole diameter that rises, it can be with above-mentioned flaring
Processing technology, throat processing method share a set of support plate 1, fixation member and sizing system, it is only necessary to replace sizing component and
Push module.In this way, the utilization rate of equipment can be greatly improved, production and processing cost is saved, reduce processing site occupied area.
Be it is necessary to described herein finally: above embodiments are served only for making technical solution of the present invention further detailed
Ground explanation, should not be understood as limiting the scope of the invention, those skilled in the art's above content according to the present invention
The some nonessential modifications and adaptations made all belong to the scope of protection of the present invention.
