Technical Field

The utility model relates to the technical field of salt bath heat treatment, in particular to a salt bath heat treatment device for a precision part.

Background

The salt bath heating is to heat and quench the workpiece by using molten salt, and compared with the common air medium furnace, the salt bath heating has the advantages of high heating speed, good quality, less decarburization and oxidation loss, and less heat treatment deformation because the workpiece is heated in a hanging state.

The existing salt bath heat treatment device generally puts salt into a salt bath, then heats the salt through the salt bath, then pours the salt into a quenching cavity to contact with a precision piece after heating the salt, and performs quenching treatment through the salt in a molten state;

however, when the precision piece is quenched, the precision piece is generally placed in a quenching cavity to be in a stacked state, the precision pieces in the stacked state are contacted with each other, and the contact part between the salt solution and the precision piece is difficult to contact, so that the quenching effect of some parts of the precision piece is poor, the effects of the salt bath on oxidation and decarburization of the precision piece are reduced, the quenching decarburization effect of the device on the precision piece is poor, and the accurate operation of the device is easily affected due to the fact that the carbon content in the precision piece is more.
