Abstract
The invention relates to a roundness correcting device for a U-shaped stainless steel pipe. The device comprises a U-shaped stainless steel pipe and a hydraulic machine, wherein a platform is fixed at the inner bottom of the hydraulic machine; a movable platform is arranged above the platform and is connected with an elevating platform on the top of the hydraulic machine through a lifting rope; and the U-shaped stainless steel pipe is arranged on the platform; and a circular groove is formed at a position on the movable platform, corresponding to the U-shaped stainless steel pipe. The device has the advantage that: the roundness of the outer diameter of the steel pipe can be corrected.
Description
Technical field
The present invention relates to a kind of circularity school round belting, relate in particular to a kind of stainless steel U type pipe circularity school round belting.
Background technology
Stainless steel U type pipe is mainly used in the low high-pressure heater in power station, and the external diameter circularity precision of steel pipe is not high, can have a strong impact on product and in use sternly not leak because of air-tightness, causes the accident, and therefore requires very high to pipe quality.Especially the high-accuracy ferrite stainless steel pipe of used in nuclear power station is had higher requirement to the external diameter circularity precision of steel pipe.
The stainless-steel pipe not up to standard to external diameter circularity in the prior art mainly scrapped it and reclaimed reprocessing, caused great waste.This has not only improved the production cost, also can influence production efficiency of products.
Be necessary to design a kind of stainless steel U type pipe circularity school round belting.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of stainless steel U type pipe circularity school round belting, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention includes: stainless steel U type pipe; Also comprise: a hydraulic press; A platform is fixed in bottom in described hydraulic press; Above described platform, settle a mobile platform; Described mobile platform links to each other by the lifting platform of lifting rope with the hydraulic press top; Described stainless steel U type pipe is placed on the platform, on mobile platform, the position of corresponding stainless steel U type pipe is provided with a circular trough.
Compared with prior art, the invention has the beneficial effects as follows: can effectively proofread and correct outer diameter of steel pipes circularity.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
As seen from Figure 1: the present invention includes: stainless steel U type pipe 1; Also comprise: a hydraulic press 2; A platform 3 is fixed in bottom in described hydraulic press 2; Above described platform 3, settle a mobile platform 4; Described mobile platform 4 links to each other with the lifting platform 6 at hydraulic press top by lifting rope 5; Described stainless steel U type pipe 1 is placed on the platform 3, on mobile platform 4, the position of corresponding stainless steel U type pipe 1 is provided with a circular trough 41.
Adopt timing of the present invention, the circular trough of fixed platform is put at the be above standard position of external diameter of stainless steel U type external diameter of pipe, under the effect of hydraulic press, lifting platform promotes mobile platform and moves down with fixed platform and combine, and the projection of the overproof diameter of stainless steel tube is under the extruding force stepless action of two platform circular openings and carry out circularity and proofread and correct.
The present invention can effectively proofread and correct outer diameter of steel pipes circularity, does not also stay the phenomenon that impression etc. influences product surface quality in steel tube surface, through the material resources performance measurement variation of steel tube performance is not also arranged, and has guaranteed the quality of product.Solve original defective work waste and reclaimed the phenomenon of reprocessing, reduced the production cost of company, improved the productivity effect and the economic benefit of company.
