Abstract
The invention discloses a tempering adjusting device of a thin-walled cylinder body, belonging to the technical field of technological equipment. The tempering adjusting device is mainly used for tempering adjustment of the metal thin-walled cylinder body after heat treatment quenching and has the main technical characteristic of comprising a cone 1, a movable swelling block 2, a pulling plate 3, a screw 4, a check ring 5, a gasket 6 and a large nut 7, wherein the movable swelling block 2 is divided into three equal conical petals; the outer surface cone angle of the cone 1 is consistent to the inner surface cone angle of the movable swelling block 2 and is matched with the cone 1 through the three-petal type movable swelling block 2 with conicity; and the movable swelling block 2 swells the thin-walled cylinder body to be round under the action of the axial movement of the screw 4. The invention synchronously adjusts and tempers the quenched thin-walled cylinder body, can effectively eliminate the quenching deformation of the thin-walled cylinder body and enhance the tempering precision and has simple and reasonable structure, convenient and reliable operation, low manufacturing cost, and the like.
Description
Technical field
The present invention relates to a kind of tempering adjusting device of thin-walled cylinder body, belong to the Equipment Technology field, it is mainly used in the tempering adjusting behind the metal thin-wall cylindrical shell heat-treatment quenching.
Background technology
Round shape thin-wall part processing because of its wall thin and 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 round 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 thermal treatment, also can eliminate heat treatment deformation by follow-up precision work, but these method technological processs are more loaded down with trivial details, labour intensity is big simultaneously, particularly for not needing accurately machined round shape thin-wall part after the thermal treatment, handle its distortion also needs to increase school shape operation one, has influenced production efficiency again.For overcoming above deficiency, tempering adjusting device of thin-walled cylinder body is developed.
Summary of the invention
Technical problem to be solved by this invention is that a kind of tempering adjusting device of thin-walled cylinder body 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 strain of thin-wall barrel, improve the tempering precision.
The technical scheme that the present invention solves its technical problem employing 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 hole 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 outside surface cone angle of cone is consistent with the internal 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, screw rod passes the centre hole of back-up ring, after loading onto packing ring, the big nut spinning is on screw rod.The present invention compares 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.
