Abstract
The utility model discloses a cold correction tooling and belongs to the field of steel pipe correction equipment. The cold correction tooling comprises a semi-closed positioning frame in line symmetry, wherein two hooks are arranged at two ends of the positioning frame; a supporting plate is arranged in the positioning frame and is vertical to the connection line of the two ends of the positioning frame; the two hooks face towards the same direction, and are vertical to the connection line of the two ends of the positioning frame; an auxiliary supporting plate is also arranged in the positioning frame; and two ends of the auxiliary supporting plate are respectively connected with the middle position of the supporting frame and the middle position of the positioning frame. The cold correction tooling is convenient and simple to use, and is particularly suitable for correcting a bent welded junction on an argon welding frame; moreover, the cold correction tooling can rotate in 360 DEG, and meets the correction requirements in any direction; as an arc-shaped positioning frame, particularly a semicircular positioning frame is adopted, the cold correction tooling is more convenient to machine and manufacture.
Description
Technical field
The utility model relates to a kind of means for correcting, particularly a kind of cold calibration device.
Background technology
In Industrial Boiler manufacturing process, pipe argon arc welding butt joint is the important procedure that influences product quality, this operation is in actual production, the control of pipe linearity can not reach ideal effect, thereby influence product quality, and select correct bearing calibration extremely important, common bearing calibration is cold school and hot school.
Though can improving, hot school changes pipe bending degree problem, but product quality there is big influence, because the temperature in hot school is wayward, only relying on naked eyes is inaccurate to the judgement of grilled gun flame temperature, temperature is low excessively, the trimming process difficulty, temperature is too high, superheating phenomenon will appear in welding junction, form structure thereby change product material, the mechanical performance of material may change, boiler under operation under the situation of HTHP in the course of time, overheated place joint just goes wrong by (possible booster) easily, influences product service life.
Also be useful at present cold frock, it is made up of the machine frame of a location, a pneumatic shuttle and an ejector pin, this cold gyp's dress only is suitable for pipe single, no elbow and proofreaies and correct, this frock not only volume is big, heavy, and limitation is very big, can't proofread and correct the pipe that a plurality of elbows are arranged.
The utility model content
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of can adorning the arbitrarily angled novel cold gyp who proofreaies and correct of addressing the above problem.
The technical solution adopted in the utility model is such: a kind of cold gyp's dress, comprise semiclosed shape and locating rack that be the line symmetry, be provided with two hooks at the two ends of described locating rack, in described locating rack, be provided with gripper shoe, described gripper shoe is vertical with the two ends line of locating rack, described two hooks towards consistent and all perpendicular to the line at locating rack two ends.
As preferably: also be provided with an auxiliary support plate in described locating rack, the two ends of described auxiliary support plate link to each other with the centre position of gripper shoe and the centre position of locating rack respectively.
As preferably: described locating rack is an arc.
As preferably: described locating rack is semicircle.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are: easy to use, simply, be specially adapted to that on the argon welding shelf weld bond is carried out the weld bond bending and proofread and correct, rotatable 360 deg satisfies the alignment requirements of any direction, adopt the especially semicircular locating rack of arc, the processing and manufacturing of more convenient cold gyp's dress.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Embodiment 1:
As shown in Figure 1, the locating rack 1 of present embodiment is semicircular round steel, processing method is: use 25 millimeters of diameters, the round steel that length is 1200 millimeters, bend a hook 2 respectively at the round steel two ends, linking up with 2 interior diameters is 60 millimeters, referring to Fig. 2, then the remainder round steel is bent into the semicircle of R200, constitute locating rack 1, link up with 2 downward 130 millimeters locate to weld gripper shoe 3, a block plate is welded at locating rack 1 center and gripper shoe 3 centers, as assist location plate 4, gripper shoe 3 and auxiliary support plate 4 are used to support jack 6, jack 6 can be distributed to whole strength on the whole frock, during operation, when stressed referring to Fig. 3, the utility model is hung on the pipe to be corrected by linking up with 2, and the weld bond 5 of pipe to be corrected is aimed at gripper shoe 3 centers, and jack 6 is placed on the gripper shoe 3, just can proofread and correct required correction weld bond 5.Use 5 tons of jack, the recoverable external diameter is less than 60 millimeters, and wall thickness is less than 10 millimeters pipe weld bond.The utility model is easy to use, and is simple, is specially adapted on the argon welding shelf weld bond to be carried out the weld bond bending and proofreaies and correct, and rotatable 360 deg satisfies the alignment requirements of any direction, adopts semicircular locating rack, the processing and manufacturing of more convenient cold gyp's dress.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; such as; locating rack can also adopt " v " shape, the wherein square or the square of openings at one side wherein of openings at one side; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
