Abstract
A thin-wall cylinder shape correction device belongs to the technical field of process apparatus, and is mainly used for correcting the shape of a thin-wall cylinder by tempering after heat treatment and quenching. The thin-wall cylinder shape correction device is mainly characterized in that the device comprises a taper body (1), a movable expansion block (2), a draw plate (3), a screw (4), a retaining ring (5), a gasket (6), and a large nut (7), wherein the movable expansion block (2) includes three identical taper section-shaped structures; the taper angle of the outer surface of the taper body (1) is equal to that of the inner surface of the movable expansion block (2); the movable expansion block (2) is matched with the taper body (1) through the three section-shaped structures with taper degree; the movable expansion block (2) is driven by the screw (4) performing axial movement to round the thin-wall cylinder. Accordingly, the shape correction and tempering process are carried out synchronously on the quenched thin-wall cylinder to effectively eliminate the quenching deformation of the thin-wall cylinder, thereby improving the tempering accuracy. The thin-wall cylinder shape correction device has the advantages of simple and reasonable structure, convenient and reliable operation, low manufacture cost and so on.
Description
Technical field
The utility model relates to a kind of thin-wall barrel corrector, belongs to the Equipment Technology field, and it is mainly used in the tempering adjusting behind the metal thin-wall cylindrical shell heat-treatment quenching.
Background technology
Cylindrical shape thin-wall part processing because of its wall thin and the wall thickness difference is little (≤0.05mm), very easily produce distortion in the heat treatment process.In the background technology, the distortion that produces in the cylindrical shape thin-wall part heat treatment process generally is by manually it being carried out cold school and school shape is come in hot school after heat treatment, also can eliminate heat treatment deformation by follow-up fine finishining, but these method technical process are more loaded down with trivial details, labour intensity is big simultaneously, particularly for not needing accurately machined cylindrical shape thin-wall part after the heat treatment, handle its distortion also needs to increase school shape operation one, has influenced production efficiency again.For overcoming above deficiency, the thin-wall barrel corrector is developed.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of thin-wall barrel corrector will be provided, it cooperates by multi-clove type band tapering activity rising piece and cone, thin-wall barrel after quenching is carried out school shape and tempering synchronously, can effectively eliminate the quenching distortion of thin-wall barrel, improve the tempering precision.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises cone, the activity piece that rises, arm-tie, screw rod, back-up ring, packing ring, big nut, arm-tie is welded in the stop portion of cone cavity, one end of screw rod is welded in the centre bore of arm-tie, cone, arm-tie, screw rod forms an integral body through welding, the activity piece that rises is trisection or many five equilibriums circular cone lobe block structure, the conical surface angle of cone is 5-7 °, the outer surface cone angle of cone is consistent with the inner surface cone angle of the movable piece that rises, the inner conical surface of the male cone (strobilus masculinus) of cone and the movable piece that rises coincide, activity rises by the end face of the less side of piece bore near the seam of back-up ring, cone rises in the piece from the activity bigger end of the piece bore activity of packing into of rising, screw rod passes the centre bore of back-up ring, after loading onto packing ring, the big nut spinning is on screw rod.
The utility model is compared the beneficial effect that is produced with background technology
1, cooperates by multi-clove type band tapering activity rising piece and cone, thin-wall barrel after quenching is carried out school shape and tempering synchronously, can effectively reduce thin-wall barrel irregular distortion in the drawing process behind heat-treatment quenching, significantly improve the precision after the thin-wall barrel tempering.
2, have characteristics such as simple and reasonable, easy to operate, safe, reliable, low cost of manufacture.
