Abstract

The invention relates to a quenching machine tool capable of preventing bending deformation of a slender rod piece during quenching. The quenching machine tool comprises a tool body, a track, a bracket mechanism and quenching equipment installed on a numerical control sliding table. The bracket mechanism consists of a headstock and a tailstock disposed on the track, and two sets of middle supporting frames. The headstock is provided with a spring clamp head and a drive motor, and the tailstock is provided with a live center and a drive air cylinder. Each middle supporting frame comprises a base, a center frame and three center frame rollers installed on the center frame. The three center frame rollers are arranged in the shape of an isosceles triangle. After loading, the wheel surfaces press against a rod body. Both ends of the rod piece are fixed through the spring clamp head and the live center. The to-be-quenched part of the rod piece is positioned between the two sets of middle supporting frames. The rod body passes through the voids between the three rollers on the center frame. During quenching, the motor drives rapid rotation of the rod piece through the spring clamping head, so that the rod piece can be evenly heated and cooled. And through the action of the three center frame rollers, bending deformation of the rod piece is further restricted, and the quality of the quenching piece is improved.

Description

technical field [0001] The invention belongs to the field of mechanical processing, in particular to a quenching machine tool capable of preventing slender rods from being bent and deformed during the quenching process. Background technique [0002] Quenching machine tool is a general equipment for heat treatment of mechanical parts. Parts can greatly improve the strength, hardness, wear resistance, fatigue strength and toughness of steel through quenching process, so as to meet the different requirements of various mechanical parts and tools. However, the slender rods are particularly prone to bending deformation during the medium-high frequency quenching process. In this field, there is no good solution to this problem. Usually, the bent and deformed rods after quenching are processed in the later stage. Calibration, complex procedures, low production efficiency. Contents of the invention [0003] Aiming at the problems existing in the prior art, the technical purpose o...
