Description

A kind of multilayer feeding type heat treatment furnace

The utility model relates to a kind of multilayer feeding type heat treatment furnace.

The manufacturing of little spring is mostly prior to being cold drawn to required size under the room temperature at present, and then tempering is to increase the toughness of spring, its means are: little spring is sent in the heat treatment furnace heated, and after the thermal treatment stove is sent, promptly combine in the container in little spring, and under room temperature, put, arrive room temperature up to little spring naturally cooling (cooling); So [heat treatment furnace] of present spring, can only be called [process furnace] in fact, because most important in the thermal treatment [cooling condition], [heat treatment furnace] do not provide controllable environment, little spring is sent from the thermal treatment stove and is directly entered in the container, (first processor) below the container and above container (aftertreatment person), obviously the cooling environment is inconsistent, in addition, the change of ventilated environment (for example the workman uses electric fan) arround the heat treatment furnace all causes the shortcoming of streaking one after the little spring thermal treatment.

[heat treatment furnace] (being process furnace) of spring has three kinds of not same attitudes at present:
