Description

Technical Field

[0001] The present invention relates to the technical field of heat treatment, in particular to a full-automatic forging heat treatment operating machine. Background Art

[0002] Forgings refer to workpieces or blanks obtained by forging and deforming metal billets. By applying pressure to the metal billet, it causes plastic deformation, which can change its mechanical properties. After forging, the forgings need to be heat treated.

[0003] During the forging process, annealing, normalizing, quenching and tempering steps are generally required. These steps need to be carried out in different furnace bodies, and the forgings need to be transferred between different furnace bodies. The transfer of forgings is generally carried out through a heat treatment manipulator. The existing heat treatment manipulator has a slow movement speed and is not accurately positioned, which to a certain extent affects the transfer time of forgings between furnace bodies and affects the effect of heat treatment. On the other hand, during the operation of the heat treatment manipulator, in order to increase its movement speed, a roller is generally used as a power to drive the slider to move on the slide rail. Since the wear resistance of the roller is much smaller than that of the slider, after a period of use, there will be a gap between the roller and the slide rail, causing the roller to slip when rotating, affecting the normal use of the heat treatment manipulator.
