Description
Technical field
The utility model relates to a kind of thermal treatment unit, particularly a kind of easy and simple to handle, production efficiency is high, constant product quality and the free of contamination gas shield quenching furnance of Working environment.
Background technology
In the mechanical industry production course of processing, all to use thermal treatment unit, wherein heating quenching device adopts high, middle thermohaline to bathe quenching furnance, its facility investment height, and complex process mostly.
In view of this, this creator develops the utility model according to oneself practical experience and technical concept.
The utility model content
The utility model is that a kind of gas shield quenching furnance will be provided, with solution make that it is easy and simple to handle, production efficiency is high, constant product quality and the free of contamination technical problem of Working environment.
It is such solving the problems of the technologies described above the technical scheme that is adopted:
A kind of gas shield quenching furnance, comprise a body of heater and electrical control gear, be provided with boiler tube in the body of heater, boiler tube is provided with resistance electricradiator, thermal insulation layer and thermofin outward, it is characterized in that: this boiler tube one end sealing, and termination is established a sealed quenching protective guard in addition, this protective guard external end head is provided with movable fire door, quenching protective guard lower end is provided with oil-quenching tank, and oil-quenching tank is placed on the oil groove railway carriage, is provided with netted hand basket in the oil-quenching tank;
This boiler tube blind end is communicated with the inlet pipe of a shielding gas;
This quenching furnance is equipped with the push rod that stretches into boiler tube, and the push rod front end is provided with workpiece cassette.
The utility model is improved with resistance furnace, boiler tube one end sealing with body of heater, termination is established sealed quenching protective guard in addition, during work, the boiler tube blind end feeds protective gas by inlet pipe, get rid of by the air outlet by the quenching protective guard again, this protective gas is a hydrogen, nitrogen, rare gas element or hydrogen-nitrogen mixture gas, when leading to hydrogen, hydrogen will be lighted by the movable fire door place of quenching protective guard, workpiece to be quenched is heated in shielding gas, after reaching quenching temperature, workpiece is sent back to quenching protective guard top, and upset is put into oil-quenching tank with workpiece and is carried out quench treatment with push rod, workpiece after the quenching is taken out by netted hand basket, reaches the high quality quenching purpose to workpiece; Thereby solved and made that it is easy and simple to handle, production efficiency is high, constant product quality and the free of contamination technical problem of Working environment.
The utility model is simple in structure, and its advantage is as follows:
1, the utility model is a gas shield warming apparatus, and quick heating, homogeneous heating during quenching have prevented the workpiece oxidation, and quenching workpiece light, steady quality have improved quality product.
