Abstract
The utility model discloses a tool used for preventing opening cylinder from heat treatment deformation. The tool comprises a V-block (3) which is similar to a shoe-shaped silver ingot, and support bars (4), wherein the V-block (3) is used as a support seat of a cylinder, and the radius of curvature of the contacting part of the V-block (3) and the outer wall of the cylinder (1) is equal to or slightly greater than the outer diameter of the cylinder; and the V-block is fixed on a shelf rest (5), and the support bars (4) are arranged in the cylinder and are used for supporting the cylinder (1) of which two ends are not provided with an end socket or can not be supported. The V-block is adopted to be used as the heat treatment support, and can effectively prevent the heat treatment deformation. The cylinder after heat treatment can meet a size requirement without being subjected to an adjustment process, thereby being beneficial to improving the product quality, and shortening the manufacturing cycle.
Description
Technical field
The utility model belongs to the thermal treatment field, relates in particular to a kind of opening cylinder body heat that prevents and handles the frock of distortion.
Background technology
Because the cylindrical shell size of pressurized vessel is bigger, adopt integral body to advance the method that stove carries out postweld heat treatment usually.Cylindrical shell directly was placed on the thermal treatment shelf rest in the past, and both sides add chock and roll to prevent cylindrical shell.But after the thermal treatment, cylindrical shell depression in chock place influences the cylindrical shell quality.For the thin-walled large-diameter cylinder body, barrel distortion (cylindrical shell becomes ellipse) also can appear, needs could satisfy the drawing dimensional requirement through complicated correcting process, influence the manufacturing cycle of product.Usually pressurized vessel needs through several intermediate heat treatment (ISR) in manufacturing processed, and the part container is long because of the length limit, needs segmentation to carry out final thermal treatment (PWHT).At this moment, there is the phenomenon (being that the cylindrical shell end does not have end socket or other members) of opening cylindrical shell, when heat-treating,, can makes the opening cylindrical shell metamorphism occur if do not take certain preventing deformation measure.Therefore, when cylindrical shell carries out intermediate heat treatment (ISR) or the final thermal treatment of segmentation (PWHT), need the assembling anti-deformation tool to prevent barrel distortion.
It is very important to preventing heat treatment deformation to design and make effective heat treatment deformation frock.Confirm the best method of use of a cover frock, heat treatment deformation reduced to ideal effect, to improve the quality of products, simplify correcting process, shortening all can be played favourable effect the manufacturing cycle.
The utility model content
The utility model technical problem to be solved provides a kind of opening cylinder body heat that can prevent and handles the frock of distortion.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of opening cylinder body heat that prevents is handled the frock of distortion; This frock comprises the V-block and the support bar of similar ingot, and this V-block is as the bearing of cylindrical shell, and the radius-of-curvature of itself and cylinder body outer wall contact position equals or bigger and cylindrical shell external diameter; V-block is fixed on the shelf rest, and support bar is used to be contained in the cylindrical shell and supports the opening of cylindrical shell.
The opening cylindrical shell that does not have end socket or other supports for two ends; At the inboard support bar of placing of the opening part of cylindrical shell; Support bar supports at the cartridge openings place vertically; The two ends of support bar are welded on the inwall of cylindrical shell, and welding material is selected the wlding consistent with the cylindrical shell circumferential weld, and support bar is apart from the position of cartridge openings end 100～150mm.The placement of V-block should make the cylindrical shell stress balance even, and the cylindrical shell end is apart from the about 1000 ~ 1500mm of the distance of V-block.When adapter was housed on the cylindrical shell, V-block should avoid taking over the position, can suitably adjust the distance of cylindrical shell end to V-block.Remove support bar after the thermal treatment, the MT inspection is carried out in dismounting place.
Adopt V-block as the thermal treatment bearing, support bar can effectively prevent heat treatment deformation as the support at cartridge openings place.Need not pass through correcting process after the cylindrical shell thermal treatment and can satisfy dimensional requirement, help improving the quality of products, shorten the manufacturing cycle, and support bar be with low cost, easy to use, in opening cylinder body deformability tendency hour, be the ideal anti-deformation tool.

Fig. 1 is the synoptic diagram of utilization the utility model.
Embodiment
As shown in Figure 1, there is not the opening cylindrical shell 1 of end socket or other supports for two ends, design and make the heat treatment deformation frock; This frock comprises the V-block 3 and support bar 4 of similar ingot; V-block 3 is placed on the shelf rest 5, then cylindrical shell 1 is placed on the V-block 3, and V-block 3 is identical basically with the radius-of-curvature and the cylindrical shell external diameter of cylindrical shell 1 contact position; Make cylindrical shell 1 outer wall and V-block 3 uniform contact, at the cylindrical shell 1 inboard support bar 4 of placing.The placement of V-block 3 should make cylindrical shell 1 stress balance even, and opening cylindrical shell 1 end is apart from the about 1000 ~ 1500mm of the distance of V-block 3.When adapter was housed on the cylindrical shell 1, V-block 3 should avoid taking over the position, can suitably adjust the distance of opening cylindrical shell 1 end to V-block 3.Support bar 4 supports at the cartridge openings place vertically, and the two ends of support bar 4 are welded on the inwall of cylindrical shell 1, and welding material is selected the wlding consistent with the cylindrical shell circumferential weld, and support bar is apart from the position of cartridge openings end 100～150mm.
Claims (1)
1. one kind prevents that the opening cylinder body heat from handling the frock of distortion; It is characterized in that; Said frock comprises the V-block (3) and the support bar (4) of similar ingot, and said V-block (3) is as the bearing of cylindrical shell (1), and the radius-of-curvature of itself and cylindrical shell (1) outer wall contact position equals or bigger and cylindrical shell external diameter; Said V-block is fixed on the shelf rest (5), and said support bar (4) is used for vertically being contained in the cylindrical shell (1) and supports the opening of cylindrical shell.
