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 [0001] The invention relates to a tempering and shaping device for a thin-walled cylindrical body, which belongs to the technical field of process equipment and is mainly used for tempering and shaping a metal thin-walled cylindrical body after heat treatment and quenching. Background technique [0002] Due to the thin wall and small wall thickness difference (≤0.05mm) in the processing of cylindrical thin-walled parts, deformation is easily generated during heat treatment. In the background technology, the deformation generated during the heat treatment of cylindrical thin-walled parts is generally corrected by manually performing cold correction and heat correction after heat treatment, and the heat treatment deformation can also be eliminated through subsequent finishing. However, these methods The process is cumbersome and labor-intensive, especially for cylindrical thin-walled parts that do not need to be finished after heat treatment. To deal with their...
