Description
Technical field
The utility model relates to the cylindrical member preparing technical field, is a kind of spinning variable cross-section mould for preparing the great diameter and long tubular workpiece of outward flange in the band.
Background technology
Along with the development of causes such as the Aeronautics and Astronautics and the energy, major diameter (internal diameter is greater than the 450mm) long tubular workpiece (greater than 3m) of outward flange is got more and more and is used in these fields in the band.On existing Equipment Foundations, use conventional spinning cylindrical mould can only process the straight cylindrical member of not being with interior outward flange.And adopting the forging blank method of machining again, present casting set pattern lattice and Forging Technology are difficult to realize producing the great diameter and long tubular workpiece of being with interior outward flange.For this reason, according to the vertical spinning machine of existing 2m, the spinning roller stroke has only 1.6m, need design variable cross-section mould, adopt the method for positive and reverse return combination, just can shape out the great diameter and long tubular workpiece of outward flange in the band, with the needs of the development of satisfying causes such as the Aeronautics and Astronautics and the energy.
Summary of the invention
The purpose of this utility model provides a kind of spinning variable cross-section mould, and it is specially adapted to internal diameter greater than 450mm, the length great diameter and long tubular workpiece spinning greater than outward flange in the band of 3m.By the variable cross-section mould, adopt the positive and negative method that combines of revolving, can have only the vertical spinning machine mould pressing of the 2m of 1.6m to go out the cylindrical member of outward flange in the 3m band at the spinning roller stroke.
For achieving the above object, the utility model is taked following design:
A kind of spinning variable cross-section mould, it is characterized in that, it includes a spinning variable cross-section core, described spinning variable cross-section core is to be connected and composed by one section big tubular core and one section little tubular core one, lower end at big tubular core is connected with big disk, on the big tubular core on the big disk, be with cutting-off bushing, on the little tubular core of big tubular core upper end, be socketed with the material loading ring, on the termination of little tubular core, be with fixed cap, protrude a location square column in the upper end of little tubular core, be provided with at the center of fixed cap and locate the square hole that square column cooperates.
In order to be connected and fixed lid, the both sides of the location square column on little tubular core are provided with screw, are provided with bolt hole in the corresponding position of fixed cap upper end, and described fixed cap is fixedlyed connected with the upper end of little tubular core by bolt.
Slide in order to prevent that blank end from producing, the upper surface of described cutting-off bushing is provided with lobe, and the lower surface of described material loading ring is provided with down lobe.
During use, at first with spinning variable cross-section mold heated; Be heated to 300～350 ℃; Then the spinning blank is lifted on the variable cross-section mould, treat to load onto the material ring behind the blanking, install fixed cap additional, entangle the spinning blank firm; Hot spinning blank to 250～280 ℃ are begun blank is carried out forward flow forming by pinch roller then, and the blank tubular is prolonged downwards, if touching cutting-off bushing should stop spinning at once, prevent barrel distortion; Dismantle upper end fixed cap and material loading ring then, blank is carried out backward spinning pressure, the blank tubular is upwards prolonged, reach outward flange cylindrical member in the band more than 3 meters, at last, treat cylindrical member cooling after, it is lifted on the lathe, the machining outward flange cylindrical member in the needed band that is shaped is carried out finished machined again after heat-treating then.
The utility model has the advantages that:
1, the spinning variable cross-section mould inside and outside flange that can be shaped and to satisfy the demand;
2, remedied the deficiency (comparatively domestic big spinning machine spinning roller stroke 1.6m is only arranged) of existing equipment condition, can rotary pressing processing have gone out cylindrical member greater than 3 meters;
3, the rotary pressing processing cylindrical member of coming out can reach the AA level through flaw detection;
4, production process is simple, and is easy to operate, and production is stability and favorable reproducibility as a result;
5, the great diameter and long tubular workpiece that is suitable for outward flange in the production band in batches.
