Lifting-type spray quenching machine tool for large thin-walled cylinder

Abstract

The invention provides a lifting-type spray quenching machine tool for a large thin-walled cylinder. The lifting-type spray quenching machine tool comprises a rotary spray quenching system, a hydraulic jacking platform, a box-type frame supporting and guiding device and a water supply and drainage system, wherein the rotary spray quenching system surrounds the inner side and the outer side of a cylindrical workpiece; the rotary spray quenching system is used for evenly spraying water to the inner side and the outer side of the workpiece to quickly cool the surface of the workpiece; the hydraulic jacking platform is used for supporting the rotary spray quenching system and adjusting the height of the rotary spray quenching system; at the same time, the hydraulic jacking platform enables therotary spray quenching system to rotate around the hydraulic jacking platform in a spray quenching process; the box-type frame supporting and guiding device is arranged outside the hydraulic jackingplatform; the box-type frame supporting and guiding device is used for fixing and supporting the hydraulic jacking platform and guiding the vertical lifting and lowering thereof; the water supply anddrainage system is used for supplying water to the rotary spray quenching system in the spray quenching process of the workpiece; and at the same time, the water supply and drainage system realizes pressure detection and return water collection in the spray quenching process. The lifting-type spray quenching machine tool for the large thin-walled cylinder can evenly spray water to the inner side and the outer side of the workpiece through the rotary spray quenching system so as to quickly cool the surface of the workpiece, thereby quickly and effectively breaking a vapor blanket on the surfaceof the quenched workpiece, improving heat transfer efficiency, and reducing deformation.

Description

technical field [0001] The invention belongs to the technical field of large-scale thin-wall cylinder body quenching and cooling process production equipment, and in particular relates to a large-scale thin-wall cylinder lift-type spray quenching machine tool. Background technique [0002] Large thin-walled cylinders are often used in aerospace, cutting-edge weapons and other fields. They have the characteristics of high product precision requirements, large single size and heavy weight. As an important step in the heat treatment of workpieces, the quenching and cooling of large thin-walled cylinders is related to the structure and deformation size of workpieces, and directly determines the performance of the final product. [0003] Traditional thin-walled cylinders are usually transported by hanging and quenched by immersion water tanks. When the diameter of the cylinder increases, the traditional immersion quenching method is prone to deformation due to excessive internal...

AI Technical Summary

Problems solved by technology

When the diameter of the cylinder increases, the traditional immersion quenching method is prone to deformation due to excessive internal stress. At the same time, a larger quenching tank is required, and more stirring devices are required for the stirring of the quenching medium. The processing is difficult and expensive. High cost and poor workpiece adaptability

[0004] The hanging method takes a long time to transfer large workpieces, and the lifting is difficult, so it is difficult to meet the short quenching transfer time requirements of thin-walled parts

Manual hoisting operations are often affected by human factors, making it difficult to guarantee product consistency and stability

[0005] To sum up, traditional quenching methods are difficult to meet the quenching needs of such parts, and it is urgent to design quenching equipment with controllable cooling rate, high cooling intensity, and a wide range of workpiece sizes according to the characteristics of large thin-walled cylinders.
