Abstract
A shaping stretcher of a ceramic lining compound oil tube comprises a hydraulic station, a hydraulic cylinder, a backing seat, and a backing bar, wherein one end of the backing bar is welded on the backing seat, the other end is connected on the hydraulic cylinder, the backing seat is provided with a static pulling head, the hydraulic cylinder is provided with a dynamic pulling head, the dynamic pulling head and the static pulling head are both provided with clamp ports, and a clamp is slidingly equipped inside the clamp port. The utility model has the advantages that the residual heat of thermit reaction is fully made use of, the ceramic lining compound oil tube is pulled straight within quite short time, and the 1/1000 line degree of the standard demanding is ensured.
Description
Technical field:
The utility model belongs to from spreading the ceramic-lined steel pipe technical field, especially relates to the supporting shaping stretching-machines of overlength centrifuge a kind of and production 10 m long ceramic liner composite oil pipes.
Background technology:
At present, because the ceramic-lined steel pipe length of producing is all shorter, the longest only 3 meters both at home and abroad, so the structure of centrifuge is also fairly simple, the fine solution of the problem aspect dynamic balancing.But the overlength centrifuge is careless slightly on making or operating, and can introduce the unbalanced moments of tens of Nmm.Because centrifuge speed is very high, this small unbalanced moments is enough to make tubing bending, so also there is not long like this centrifuge at present, does not also have supporting with it stretching-machine.
Summary of the invention:
Shaping stretching-machine when technical problem to be solved in the utility model aims to provide a kind of and 10 meters ceramic liner composite oil pipes of the matching used production of overlength centrifuge, to overcome the defective that background technology exists, guarantee the linearity of 10 meters ceramic liner composite oil pipes.
The technical solution of the utility model is: comprise Hydraulic Station, hydraulic cylinder, supporting seat and support bar, support bar one end is welded on the supporting seat, the other end is connected on the hydraulic cylinder by gripper shoe, 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, slip is provided with clamp in the clamp mouth.
Advantage of the present utility model is: make full use of the waste heat of thermit reaction, and stretching ceramic liner composite oil pipe in a short period of time, 1/1000 linearity of assurance standard-required.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment:
With reference to Fig. 1, Fig. 2, the utility model comprises Hydraulic Station 1, hydraulic cylinder 2, supporting seat 6 and support bar 5, support bar 5 one ends are welded on the supporting seat 6, the other end is connected on the hydraulic cylinder 2 by gripper shoe 8, supporting seat 6 is provided with one and decides pull head 7, hydraulic cylinder 2 is provided with a moving pull head 3, move pull head and decide pull head and all have two clamp mouths 4, all slide in each clamp mouth 4 and be provided with clamp 9, Hydraulic Station 1 for hydraulic oil, changes the direction of the supply of hydraulic oil to hydraulic cylinder 2, and hydraulic cylinder 2 can advance or retreat.
During use, after thermit reaction is finished in the oil pipe, treat that centrifuge stops operating, oil pipe can also keep the high temperature more than 800 ℃, the nearly 100mm of oil pipe expanded by heating.Drive hydraulic cylinder this moment and advance, moving pull head is pushed ahead, simultaneously the clamp of deciding in pull head and the moving pull head is fixed on rapidly on the pressure cap at oil pipe two ends, and change the direction of hydraulic cylinder at once, pull back, this moment, oil pipe was stretched by pulling force at once.When the Hydraulic Station Pressure gauge was indicated certain pulling force, commutation was pushed ahead hydraulic cylinder rapidly, loosens moving pull head, extracted clamp out, and ceramic liner composite oil pipe is that shaping finishes.
