Abstract
The utility model discloses a shell deformation preventing tool which comprises a bottom plate, a supporting column, a connecting plate and an arc-shaped top plate, wherein the upper surface of the arc-shaped top plate is an arc surface glued with the inner wall of a corresponding shell; the supporting column is formed by connecting one or multiple connecting tubes through flanges; the connecting tubes connected with the connecting plate are formed by connecting inner tubes and outer tubes through pin shaft sleeves; and the tube walls of the inner tubes and the outer tubes are provided with equally spaced pin shaft through holes. The manufacture process is simple, and the shell deformation preventing tool can be used for solving the deformation problem of the shell resulted from welding longitudinal seams in the machining course of a cylinder body.
Description
Technical field
The utility model relates to a kind of housing reversible deformation frock that can effectively solve processing cylinder process middle shell problem on deformation.
Background technology
In the production process of pressure vessel, an important step is the processing of pressure-bearing cylinder, being about to rectangular block roll of steel plate makes cylindric, the hoop or the longitudinal seam that adopt the mode of welding to adorn cylinder again connect, finally be processed into cylinder with certain diameter and length, because of the main pressure-containing member of cylinder as pressure vessel, corresponding production acceptance specification requires it to have quite high circularity, do not allow out after high angularity, but in the welding process of vertical hoop abutment joint, because the existence of thermal stress, as not taking appropriate measures, then inevitably can produce contraction distortion, inwardly produce corresponding too high angularity, influence the bearing capacity of product in its welding cooling back.
The utility model content
The technical problems to be solved in the utility model provides a kind of housing reversible deformation frock that can effectively solve processing cylinder process middle shell problem on deformation.
The utility model solves described problem by the following technical solutions:
A kind of housing reversible deformation frock comprises base plate, support column, connecting plate and curved roof, and the upper surface of described curved roof is the cambered surface that fits with the respective housings inwall; Described support column is formed by connecting by flange by one or more adapters; The adapter that links to each other with described connecting plate is interior pipe and outer tube by being socketed to form, and has equidistant bearing pin through hole on the tube wall of pipe and outer tube in described.
Housing reversible deformation frock described in the utility model, because the upper surface of its curved roof is the cambered surface that fits with the respective housings inwall, therefore in the welding process of processing cylinder, curved roof with the utility model housing reversible deformation frock withstands inner walls, just can prevent that housing from caving inward under the effect of thermal stress; Because described support column is formed by connecting by flange by one or more adapters, therefore, make the cylindrical shell of processing different-diameter, can select the adapter that connects varying number; Simultaneously, because the adapter that links to each other with described connecting plate is that interior pipe and outer tube are by being socketed to form, and have equidistant bearing pin through hole on the tube wall of pipe and outer tube in described, so, can also use described internal and external casing to finely tune, so that the upper surface of described curved roof and respective housings inwall fit tightly, in the process of welding, play the effect of resisting thermal stress deformation.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the composition structural representation of housing reversible deformation frock described in the utility model.
Among the figure:
1, base plate; 2, support column; 3, connecting plate; 4, curved roof; 5, take over; 6, interior pipe; 7, outer tube; 8, bearing pin.
The specific embodiment
As shown in Figure 1, a kind of housing reversible deformation frock comprises base plate 1, support column 2, connecting plate 3 and curved roof 4, and the upper surface of described curved roof 4 is the cambered surface that fits with the respective housings inwall; Described support column 2 is formed by connecting by flange by one or more adapter 5; The adapter 5 that links to each other with described connecting plate 3 is for interior pipe 6 and outer tube 7 are socketed to form by bearing pin 8, and has equidistant bearing pin through hole on the tube wall of pipe 6 and outer tube 7 in described.
In the welding process of the processing of cylinder, withstand the inner walls at corresponding longitudinal seam place with the curved roof 4 of housing reversible deformation frock described in the utility model, when making the cylindrical shell of processing different-diameter, can select the adapter 5 that connects varying number so that the length of described support column 2 is corresponding with the diameter of the cylindrical shell of processing; Then, as the case may be, can also use described internal and external casing to finely tune with bearing pin 8 with interior pipe 6 and outer tube 7 sockets; Simultaneously below of the present utility model, be used jack, the upper surface of described curved roof 4 and respective housings inwall are fitted tightly.Like this, in the processing welding process of circular cylinder body, the thermal stress that produces in the time of can eliminating welding prevents that housing from caving inward distortion and producing excessive angularity.
