Problems solved by technology
Some existing heat treatment furnaces integrate heating and quenching into one body, but such devices occupy a large area and are relatively expensive
Now there are also some devices that set the heating and cooling devices as the upper and lower structures, and transfer the materials by connecting the two devices through transmission, but the materials are transferred up and down. Due to the existence of gravity, they must be in the upper device. Load-bearing doors are set up, and the safe delivery of materials cannot be guaranteed during material delivery

The invention discloses a vacuum-induction thermal treatment furnace for shaft-type elements. A heating and heat-preserving device, a thermal treatment material supporting frame, a material preparing device and a quenching device as well as a connecting mode of the heating and heat-preserving device, the thermal material supporting frame, the material preparing device and the quenching device are improved, so that thermal treatment such as normalizing, annealing, quenching, tempering and the like of the shaft-type elements can be carried out in the thermal treatment furnace, and automation can be simply realized.
Description
technical field [0001] The invention belongs to the field of heat treatment, in particular to a vacuum induction heat treatment furnace for shaft components. Background technique [0002] The current heat treatment device usually puts the workpiece to be heat treated into the heat treatment equipment for heat treatment through a tray or a material frame, but when heat treating shaft components, it is easy to generate stress in different directions or the degree of heat treatment of each part is different, resulting in performance defects. . If a tray is used to heat-treat shaft components, the parts in contact with the tray will not be heated sufficiently during heating, and the stress distribution will be uneven because the weight is concentrated on the contact part. Circular shaft components are fine, square shafts or other shaft components with planes have a great influence. And in the heat treatment process, too many human operations make the heat treatment effect of e...
