Abstract
The utility model relates to a device for correcting the ovality of a circular steel tube, which belongs to the technical field of metal section processing equipment, and used for rapidly and accurately correcting the ovality of a circular steel tube. The device adopts the technical proposal that the device consists of a framework, a platform, a railway, a hydraulic jack, an inner fixing plate and an outer fixing plate, wherein the framework adopts a rectangular steel structure; the platform is made of a steel plate and laid on the framework; the railway is fixed along central axis of the platform; a base at the lower part of the hydraulic jack is matched with the railway; the working end of the hydraulic jack is parallel with the axes of the platform; and the inner fixing plate and the outer fixing plate are installed on the platform in sequence along the direction of the working end of the hydraulic jack. The device for correcting the ovality of the circular steel tube is positioned through the outer fixing plate and the inner fixing plate, the positions required to be corrected are pressurized through the working end of the hydraulic jack to ensure that the steel tube to be deformed, thus achieving the purpose of correcting the ovality, the device structure is simple, manpower and material resources are greatly reduced, and simultaneously the accuracy and the correcting speed are obviously improved.
Description
Technical field
The utility model relates to a kind of steel pipe contour machining equipment, belongs to the shape technical field of processing equipment.
Background technology
Widely apply steel circular tube structure spare in skyscraper and industrial circle, circular tube structure is made usually molded by roll of steel plate, therefore tends to not reach designing requirement on ovality, need adjust and proofread and correct.Heat at the position that original bearing calibration generally uses flame that needs are proofreaied and correct, and repairs with jack then.This method not only wastes time and energy, and too loaded down with trivial details and school circle precision shortcoming, can not satisfy the needs of producing and constructing.For the accuracy of enhancing productivity, improve the correction of round steel pipe ovality has, be necessary to develop a kind of equipment of proofreading and correct the steel pipe ovality that is specifically designed to.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of simple in structure, easy to use, can accurately proofread and correct the device of round steel pipe ovality fast.
The technical scheme that solves the problems of the technologies described above is:
A kind of device of proofreading and correct the round steel pipe ovality, it is made up of framework, platform, track, hydraulic jack, internal fixation plate, outer fixed head, framework is a rectangular bar of steel structure, platform is a steel plate, be laid on the framework, track is fixed along platform middle part axis, and the hydraulic jack lower base matches with track, the working end of hydraulic jack and platform axle line parallel, on the platform along the direction of hydraulic jack working end be equipped with in proper order internal fixation plate and outside fixed head.
The device of above-mentioned correction round steel pipe ovality, described outer fixed head is fixed on the platform.
The device of above-mentioned correction round steel pipe ovality, described internal fixation plate are a plurality of, and they are arranged in proper order, are the fastening structure that removably connects with platform.
The device of this correction round steel pipe ovality, the round steel pipe that needs are proofreaied and correct can be placed on the platform, fixed head and internal fixation plate are located in addition, mobile hydraulic jack, the position pressurization with proofread and correct needs the working end of hydraulic jack makes round steel pipe produce deformation, reach the purpose of calibration ellipsometer circularity, this apparatus structure is simple, has saved the man power and material greatly, all increases significantly on accuracy and correction rate simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Mark is as follows among the figure: framework 1, platform 2, track 3, hydraulic jack 4, internal fixation plate 5, outer fixed head 6, round steel pipe 7
The specific embodiment
Show among the figure that the utility model is made up of framework 1, platform 2, track 3, hydraulic jack 4, internal fixation plate 5, outer fixed head 6.Framework 1 is a rectangular bar of steel structure, is equipped with the platform 2 that steel plate is formed on framework 1, and track 3 is fixed along platform 2 middle part axis.The lower base of hydraulic jack 4 is installed on the track 3, and hydraulic jack 4 can move forward and backward along track 3, fixes after putting in place, and the working end of hydraulic jack 4 is parallel with platform 2 axis.
Internal fixation plate 5 and outer fixed head 6 are installed on the platform 2, they are on the axis of platform 2, direction along hydraulic jack 4 working ends is arranged in proper order, outer fixed head 6 apart from hydraulic jack 4 farthest, internal fixation plate 5 is outside between fixed head 6 and the hydraulic jack 4.Outer fixed head 6 is fixed on the platform 2.Internal fixation plate 5 is a plurality of, and they and platform 2 are the fastening structure that removably connects, and can select to use which internal fixation plate 5 according to the diameter of round steel pipe 7 during work, is fixed then.
Show among the figure that the utility model is when work, the round steel pipe 7 that needs are proofreaied and correct is placed on the platform 2, and outer fixed head 6 withstands on the rear portion of round steel pipe 7, and internal fixation plate 5 is positioned at round steel pipe 7, and its front end withstands on the position of the both sides, back that need the correction position.Internal fixation plate 5 and outer fixed head 6 are just with the fixed-site of round steel pipe 7 like this, and when hydraulic jack 4 was exerted pressure, round steel pipe 7 can not move.The position that needs correction will be aimed at the working end of hydraulic jack 4 in the position of mobile hydraulic jack 4 on track 3 then, and hydraulic jack 4 is fixing.Start hydraulic jack 4,, make round steel pipe 7 produce deformation, reach the purpose of calibration ellipsometer circularity the position pressurization that needs are proofreaied and correct.
