Abstract
A synchronizing locking stretching self-centering over-length centrifuge of a ceramic lining compounding vitta comprises a centrifugal portion, a self-centering locking potion and a stretching portion. The centrifugal portion comprises a shape tube, a bearing block for installing the shape tube, and a base for fixing the bearing block. The self-centering locking potion is a self-centering synchronizing locking ring which is evenly covered on the outer circumference of the shape tube. The stretching portion comprises a hydraulic station, a hydraulic tank, a supporting base, a supporting rod connecting the hydraulic station and the supporting base, and a supporting board for fixing the hydraulic tank and the supporting rod. The supporting base is provided with a fixed drawing head and the hydraulic tank is provided with a movable drawing head. The fixed and the movable drawing heads are provided with clamp mouths which are provided with clamps. The utility model ensures the coincidence of the axes of the vitta and the rotation center of the centrifuge and the dynamic balance. The tiny bending of the vitta is aligned by appropriate pull when the vitta is red and hot, therefore the straight of the vitta is ensured.
Description
Technical field:
The utility model belongs to from spreading the ceramic-lined steel pipe technical field, especially relates to a kind of centrifuge of production 10 m long ceramic liner composite oil pipes.
Background technology:
Self propagating high temperature synthetic technology (SHS) originates from the former Soviet Union, is further developed in Japan afterwards, passes to China the eighties in last century.Be divided into centrifugal process and gravitational method in the practical application, centrifugal process is used more general, and its basic principle is: the high temperature that utilizes thermit reaction to produce makes thermit reaction continue to carry out, and iron powder and aluminium powder is placed in the steel pipe, and allows steel pipe rotate at a high speed.After thermit reaction took place, under action of centrifugal force, the iron that reaction produces separated owing to proportion is different with aluminium oxide, and the former and steel pipe walls form metallurgical binding, and the latter is a mechanical bond, forms ceramic-lined steel pipe.
At present, the centrifuge of each enterprise is fairly simple both at home and abroad, generally is that motor banding pattern pipe rotates at a high speed, along the type caliber to the type that is fixed on tube wall on 120 ° the bolt chucking type pipe of being separated by in steel pipe.Because the ceramic-lined steel pipe length that each enterprise produces is generally less than 3 meters, centrifuge is realized dynamic balancing easily, and ceramic-lined steel pipe is not flexible.It is just unworkable that same method is used for 10 meters long tubes, the dynamic balancing difficulty, and elongated tubular is crooked easily.
Summary of the invention:
Technical problem to be solved in the utility model aims to provide a kind of synchronous locking overlength stretching self-centering centrifuge that guarantees dynamic balancing can guarantee to produce 10 meters long ceramic liner composite oil pipe the time, guarantees linearity, to overcome the defective that background technology exists.
The technical solution of the utility model is: comprise centrifugal part, self-centering lock portion and stretched portion, centrifugal part comprises the bearing block of type pipe, mount type pipe and the base of fixed bearing block, and the self-centering lock portion is a synchronous retaining ring of self-centering that evenly is set on the type pipe excircle; Stretched portion comprises the gripper shoe of support bar, fixer cylinder pressure and the support bar of Hydraulic Station, hydraulic cylinder, supporting seat, connection Hydraulic Station and supporting seat, supporting seat is provided with one and decides pull head, hydraulic cylinder is provided with a moving pull head, moving pull head and decide pull head and all have the clamp mouth is provided with clamp in the clamp mouth.
The synchronous retaining ring of self-centering comprises locking rotating ring and pin, and the inside circumference face of locking rotating ring has dovetail groove, and the groove bottom of dovetail groove is an inclined-plane, and the pin top is attached on the bottom land inclined-plane of dovetail groove.
The even sheathed locking rotating ring of type pipe excircle of the present utility model, the inside circumference face of locking rotating ring has dovetail groove, and the groove bottom of dovetail groove is an inclined-plane, and the pin top is attached on the bottom land inclined-plane of dovetail groove, assurance oil pipe axle center overlaps with the centrifuge pivot, guarantees dynamic balancing; Supporting seat is provided with one and decides pull head, hydraulic cylinder is provided with a moving pull head, moves pull head and decide pull head all to have the clamp mouth, and sliding in the clamp mouth is provided with clamp, guarantee when oil pipe red heat state slight curves, thereby guaranteed the linearity of oil pipe with suitable pulling force alignment oil pipe.

The specific embodiment:
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, the utility model comprises centrifugal part, self-centering lock portion and stretched portion, centrifugal part comprises the bearing block 9 of type pipe 7, mount type pipe and the base 10 of fixed bearing block, and the self-centering lock portion is a synchronous retaining ring 8 of self-centering that evenly is set on type pipe 7 excircles; Stretched portion comprises Hydraulic Station 1, hydraulic cylinder 3, supporting seat 11, connects the gripper shoe 2 of support bar 15, fixer cylinder pressure and the support bar of Hydraulic Station and supporting seat, supporting seat 11 is provided with one and decides pull head 12, hydraulic cylinder is provided with a moving pull head 4, decide pull head 12 and be provided with clamp mouth 13 and clamp 14, moving pull head 4 is provided with clamp mouth 5 and clamp 6.
With reference to Fig. 3, the synchronous retaining ring of self-centering comprises locking rotating ring 16 and pin 18, and the inside circumference face of locking rotating ring 16 has dovetail groove 17, and the groove bottom of dovetail groove 17 is inclined-planes, and pin 18 tops are attached on the bottom land inclined-plane of dovetail groove 17.
The utility model course of work is: after the installation oil pipe is put reaction raw materials well, and the rotating centrifugal part, under the effect of inertia force, self-centering lock portion rotation lock oil pipe; Behind the rotating speed of waiting to reach predetermined, finish the centrifugal part of stall at thermit reaction, under the effect of inertia force, the self-centering lock portion discharges oil pipe, starts stretched portion, keep the several seconds under predetermined pulling force, discharge stretched portion rapidly, the taking-up oil pipe cools off in air and gets final product.
