Description
Technical Field
The utility model relates to a two room air quench furnaces technical field, concretely relates to quick air quench device of two room air quench furnaces.
Background
The double-chamber gas quenching furnace is developed on the basis of a single-chamber gas quenching furnace, mainly comprises a gas quenching chamber and a heating chamber, wherein the gas quenching chamber is used for rapidly cooling a workpiece, the heating chamber is used for heating the workpiece to a process temperature, and the heating chamber is also provided with a transfer mechanism which is used for rapidly transferring the workpiece between the heating chamber and the gas quenching chamber. The gas quenching process of some high alloy steels has high requirements on the cooling speed of the workpiece, and the workpiece needs to be rapidly cooled from a specified temperature to a set temperature. In the traditional double-chamber gas quenching furnace, the temperature of a workpiece starts to drop in the transfer process of the workpiece from a heating chamber to a gas quenching chamber, and when the workpiece starts to be rapidly cooled after reaching the gas quenching chamber, the gas quenching initial temperature of the workpiece is already lower than the specified temperature, so that the gas quenching effect is reduced, and the workpiece cannot reach the technical index.
To sum up, the utility model designs a quick gas quenching device of a double-chamber gas quenching furnace.
Disclosure of Invention

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments;
fig. 1 is a schematic structural view of the present invention;
fig. 2 is a sectional view taken along line a-a of fig. 1.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
Referring to fig. 1-2, the following technical solutions are adopted in the present embodiment: the utility model provides a quick air quenching device of twin chamber air quenching furnace, includes big motor 1, transfer mechanism 2, well door 3, impeller 4, qianmen 5, heating chamber 6, air quenching room 7, heat exchanger 8 and work piece 9, air quenching room 7 both sides are provided with well door 3 and qianmen 5 respectively, are provided with impeller 4 and heat exchanger 8 in the air quenching room 7, 2 big motors 1 are installed to air quenching room 7 both sides, be provided with transfer mechanism 2 between air quenching room 7 and the heating chamber 6, transfer mechanism 2 can shift work piece 9 between air quenching room 7 and heating chamber 6 fast.
The working principle of the specific embodiment is as follows: when the quenching process is started, the motor 1 is started in a vacuum state, the impeller 4 of the gas quenching chamber 7 is driven to rotate, the middle door 3 is opened, and the workpiece 9 is transferred from the heating chamber 6 to the gas quenching furnace 7 by the transfer mechanism 2. Because the rotation of the impeller 4 can not drive the gas to flow through the heat exchanger 8 under the vacuum state, the temperature of the workpiece is not lost in the transferring process. Then the middle door 3 is closed, high-pressure nitrogen is filled, as the impeller is started at this time, low-temperature nitrogen instantly flows through the workpiece to be changed into high-temperature nitrogen, the high-temperature nitrogen is changed into low-temperature nitrogen through heat exchange, and the nitrogen continuously and circularly flows to promote the workpiece to be rapidly cooled to the set temperature from the specified temperature. The technical scheme can well ensure that the workpiece starts gas quenching from the set temperature.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
