Abstract
The invention provides a large-diameter cylinder forming detection sample plate which comprises an arc portion, an auxiliary detection position, a position datum point, a positioning butt strap and reinforced ribs. The arc radius of the arc portion is identical with the radius of a formed cylinder. Three specific auxiliary detection position detection points are distributed on an arc detection face and used for detecting the cylindricity of the cylinder. The positioning datum point is arranged at the end portion of the sample plate and is an arc. The radius of the positioning datum point is identical with that of an upper roller of a three-roller plate roller of forming equipment and the positioning butt strap is arranged on a plane of the sample plate and the reinforced ribs for improving the rigidity of the sample plate are arranged on the sample plate. The large-diameter cylinder forming detection sample plate has the advantages that as the technical scheme is adopted, the detection requirement is met when cylinder forming work is performed, the working efficiency is improved and the large-diameter cylinder forming detection sample plate is easy, practical, capable of saving capital and the like.
Description
Technical field
The invention belongs to technical field of hydraulic generators, especially relate to a kind of large-diameter cylinder body moulding and detect model.
Background technology
In hydrogenerator unit weldment manufacture process, need to use large diameter cylindrical shell, if the support wall in out frame, the yoke ring in rotor field spider etc. are all the cylindrical tubes of large (φ 3500mm ~ φ 7200mm) of barrel thicker (being generally 60mm ~ 140mm), diameter.In using three roller plate roller forming processes, must to the cylinder roundness of envelope moulding, detect at any time, to guarantee that circularity meets pattern requirement.
Summary of the invention
While the object of the invention is for the moulding of solution large-diameter cylinder body, the test problems of cylinder roundness, provides a kind of cost low, easy to use, can meet the large-diameter cylinder body moulding detection model that cylindrical shell blank centering, roundness measurement, cylindricity detection etc. require simultaneously.
Technical scheme of the present invention is: a kind of large-diameter cylinder body moulding detects model, it is characterized in that: comprise circular arc portion, auxiliary detection position, positioning datum point, location attachment strap and reinforcement, the arc radius of described circular arc portion is consistent with the radius of formed cylinder body, three specific auxiliary detection position detection points distribute on circular-arc detection face, for cylindrical shell cylindricity, detect, positioning datum point is set in model end, positioning datum point is circular arc, its radius is consistent with the top roll radius of former three roller plate rollers, location attachment strap is set in model plane, the reinforcement that improves model rigidity is set on model.
Detect model and use 0.7mm ~ 1.2mm cold-rolled steel sheet.
Advantage and good effect that the present invention has are: owing to adopting technique scheme, while carrying out cylindrical shell operations for forming, met testing requirement, improved work efficiency, had simple, practical, the advantage such as economize on the use of funds.
Accompanying drawing explanation
Fig. 1 is that the moulding under background technology detects the main TV structure schematic diagram of model;
Fig. 2 is placed on the main TV structure schematic diagram on plate roller before the moulding of steel plate blank;
Fig. 3 is placed on the plan structure schematic diagram on plate roller before the moulding of steel plate blank;
When Fig. 4 is the moulding of steel plate blank, the work schematic diagram that uses the present invention to check;

In figure: 1, circular arc portion, 2, auxiliary detection position, 3, positioning datum point, 4, location attachment strap, 5, reinforcement.
Embodiment
As Figure 2-Figure 5, a kind of large-diameter cylinder body moulding of the present invention detects model, comprise circular arc portion 1, auxiliary detection position 2, positioning datum point 3, location attachment strap 4 and reinforcement 5, the arc radius of circular arc portion 1 is consistent with the radius of formed cylinder body, three specific auxiliary detection position 2 check points distribute on circular-arc detection face, for cylindrical shell cylindricity, detect, in model end, positioning datum point 3 is set, positioning datum point 3 is circular arc, its radius is consistent with the top roll radius of former three roller plate rollers, location attachment strap 4 is set in model plane, the reinforcement 5 that improves model rigidity is set on model.Detect model and use 0.7mm ~ 1.2mm cold-rolled steel sheet.
For further understanding content of the present invention, Characteristic, now enumerate following examples, and coordinate accompanying drawing to be described in detail as follows:
1, in Fig. 2, after the steel plate of cylindrical shell blank is placed on plate roller, the top roll top of the left end of the model in Fig. 1 and plate roller is tight, with the verticality of try square detection model and the body of roll.
2, utilize the inspection line on steel plate blank, with reference to model, by blank centering, see that Fig. 3 illustrates.
3, in blank forming process, constantly use the orthodrome workplace of model repeatedly to check the moulding radius-of-curvature of blank, until cylindrical shell radius conforms to model, moulding (round as a ball) end-of-job, is shown in that Fig. 4 illustrates.
4, after cylindrical shell moulding, cylindrical shell is upright, model is ridden over to barrel port, pedal line is checked to breach hangs down along specific on model, check the distance of vertical line and barrel, to determine the cylindricity of cylindrical shell, and determine the position of proofreading and correct, see that Fig. 5 illustrates.
5, in cylindrical shell forming process, large-size cylinder body generally needs a pair of above model to check moulding, uses in pairs, makes above-mentioned work more convenient.
The multi-functional large-diameter cylinder body moulding of this example detects the use of model in cylindrical shell forming process, has shortened detection time, flexible, has improved inspection precision, has met the testing requirement of workpiece.
The present invention has the advantages such as making is simple, easy to use, low cost of manufacture, can be widely used in the manufacture process of hydrogenerator processing and manufacturing industry.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the present patent application scope and improvement etc., within all should still belonging to patent covering scope of the present invention.
