Description
Technical field
Present invention centrifugation movement rack device, belong to the technology neck of water-cooled production and its equipment manufacturing
Domain.
Background technology
In current domestic spheroidal graphite cast-iron manufacturing enterprise, most of producers are using water cooling production centrifugal ductile cast iron
Pipe, and the Core equipment of the production method is water-cooled.Every water-cooled has
One puts core clamping device, and the device is to ensure to lay cast tube sockets core and be pressed on the bellmouth position of cast tube metal die
On, centrifugal tube casting machine is ensured the bellmouth shaping of centrifugal ductile cast iron pipes in depositing.
And the core rack device of core clamping device is often because the thrust of spring is not enough or because of core frame on existing shape centrifugal tube casting machine
The factors such as the alignment pin loosening of disk influence and cause the spindle nose of core frame axle and the center portion of core frame disk directly to contact, and this phenomenon
Appearance can cause core frame disk that friction occurs with spindle nose and damages the parts such as core frame axle and the nut of core rack device when rotating, and these zero
The failure of part not only result in core frame disk work it is abnormal and occur core damage, bellmouth not be molded or bellmouth Forming Quality reach
Turn into waste product less than the cast tube for requiring and causing centrifugal tube casting machine to pour out, and also result in core rack device and directly damage to factory
Bring loss.
It is sometimes residual because of waste residue or splashing when centrifugal tube casting machine depositing in addition, because of the fault of construction of existing shape core rack device
Iron easily into the connecting portion of core frame disk and the core frame axle of core rack device and to cause core frame disk to work abnormal so that centrifugal casting
The cast tube that pipe machine pours out turns into waste product or bellmouth defect pipe.
Therefore, the core rack device of existing shape centrifugal tube casting machine is improved, is to ensure that centrifugal tube casting machine is working properly and improve cast tube
Product qualification rate, the major action for improving cast tube sockets Forming Quality.

Dynamic, the opposite side of core frame disk is provided with ball seat, and core frame disk, which is seated on the sphere of ball seat, can ensure that core frame disk all the time will
Cast tube sockets core compresses, and keeps the concentric rotation of core frame disk and core, rational in infrastructure, reliable operation, fault rate is low, while core
The stable rotation of frame disk also makes core frame axle avoid the occurrence of flexural deformation, improves the performance and service life of core frame axle,
Service life is extended while ensure that product quality, reduce cost.
2nd, the present invention is provided with the cover plate for covering core frame dish axle hole in the spindle nose of core frame axle, avoids waste residue or the residual iron of splashing
Cause the work of core frame disk abnormal into the connecting portion of core frame disk and core frame axle, improve cast tube qualification rate, extend this
The service life of invention.
3rd, between of the invention core frame axle and core frame axle bed except be equipped with two deep groove ball bearings carry out it is radially fixed outer, and also
Add a thrust ball bearing and carry out axial restraint, improve the installation accuracy of core frame axle.

With spring 9, the intermediate sleeve of core frame axle 8 is equipped with spring 9, and one end of core frame axle 8 is arranged in core frame axle bed 1 by bearing, core frame
The other end of axle 8 is set with core frame disk 5 and end is fastened and fixed by clamp nut 14, and core frame 3 also includes ball seat 6 and cone
Body set 7, the ball seat 6 is sleeved on core frame axle 8 and is seated in ball close to the side of spring 9, core frame disk 5 positioned at core frame disk 5
On the sphere of housing 6, the cone set 7 is sleeved on core frame axle 8 and inserted positioned at the opposite side of core frame disk 5, the conical surface of cone set 7
In the axis hole for entering core frame disk 5.
The spindle nose of described core frame axle 8 is provided with the cover plate 10 for covering the axis hole of core frame disk 5.
Described core frame axle 8 is radially fixed by two deep groove ball bearings 4 and core frame axle bed 1, and core frame axle 8 passes through one
Individual thrust ball bearing 11 and the axial restraint of core frame axle bed 1.
The core frame disk 5 manufactures plurality of specifications by the centrifugal ductile cast iron pipes model produced, when centrifuge 12 is poured
During note production, it can be selected according to the model of processed centrifugal ductile cast iron pipes.
Cone set 7, ball seat 6, core frame axle 8 and the core frame axle bed 1 are grouped by the core frame disk 5 of plurality of specifications, are pressed
Assemble and do several specifications, selected according to the centrifugal ductile cast iron pipes model of the production of centrifuge 12.
The spring 9 is prepared as the thrust required by core 15, can when centrifuge 12 carries out cast production
Corresponding spring 9 is selected according to the model of processed centrifugal ductile cast iron pipes.
The core frame rocking arm 2 is prior art.
The operation principle of the present invention is summarized as follows：
First, after the condition of work of centrifuge 12 possesses, manually core 15 is placed on the core frame disk 5 of core frame 3；
Secondly, operating personnel start core clamping device on centrifuge, and the projecting shaft of the device is by first " rotation " band of Driven by Hydraulic Cylinder
Core frame 3 is swinging on the center of centrifuge 12 by dynamic core frame rocking arm 2, and then the projecting shaft of the device is again by Driven by Hydraulic Cylinder
" retraction " drives core frame 3 that core 15 is pressed on the bellmouth end of pipe die 13, and now core 15 makes its pressure to the pressure of core frame disk 5
Tight spring 9 simultaneously departs from cone set 7；
Again, start centrifuge 12 to rotate, make pipe die 13 start to rotate and drive core 15 and core frame 3 to rotate with one heart, then open
