Description

Quick transfer device of work piece in two room gas quenching stove

Technical Field

The utility model relates to a two room air quenching furnace technical field, concretely relates to quick transfer device of work piece in two room air quenching furnace.

Background

The double-chamber gas quenching furnace is developed on the basis of a single-chamber gas quenching furnace, the double-chamber gas quenching furnace mainly comprises a gas quenching chamber and a heating chamber, the gas quenching chamber is responsible for rapidly cooling a workpiece, the heating chamber is responsible for heating the workpiece to a process temperature, and the heating chamber is also provided with a transfer device which is responsible for transferring the workpiece between the heating chamber and the gas quenching chamber. The gas quenching process of some high alloy steels has high requirement on the initial gas quenching temperature of the workpiece, while the traditional double-chamber gas quenching furnace has the advantages that the temperature of the workpiece begins to drop in the transfer process of the workpiece from a heating chamber to a gas quenching chamber, and the gas quenching initial temperature of the workpiece is lower than the specified temperature when the workpiece starts to be rapidly cooled after reaching the gas quenching chamber, 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 transfer device of work piece in two room gas quenching stove.

Disclosure of Invention

The utility model aims to overcome the defects in the prior art, and aims to provide a quick workpiece transfer device in a double-chamber gas quenching furnace, which has the advantages of reasonable structural design, quick workpiece transfer, accurate workpiece placement position and small temperature loss in the workpiece transfer process.

In order to achieve the above purpose, the present invention is realized by the following technical solution: a quick workpiece transfer device in a double-chamber gas quenching furnace comprises a fork arm, a fork arm motor, a screw jack and a screw jack motor, wherein the screw jack motor and the screw jack drive the fork arm to ascend and descend together, and the fork arm motor drives the fork arm to extend and retract.

Preferably, the double-chamber gas quenching furnace comprises a large motor, a transfer device, a middle door, an impeller, a front door, a gas quenching chamber, a heating chamber and the like. A transfer device is arranged between the gas quenching chamber and the heating chamber, and a middle door and a front door are respectively arranged at two sides of the gas quenching chamber.

The utility model has the advantages that: compare traditional two room air quench furnaces, neotype two room air quench furnace shifts mechanism can guarantee that the work piece shifts fast, the work piece is placed the position accurate, and the temperature loss among the work transfer process is little simultaneously.

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 to 4, the following technical solutions are adopted in the present embodiment: a workpiece rapid transfer device in a double-chamber gas quenching furnace, referring to figures 1-4, the specific implementation mode adopts the following technical scheme: a workpiece rapid transfer device in a double-chamber gas quenching furnace comprises a fork arm 2-1, a fork arm motor 2-2, a screw jack 2-3 and a screw jack motor 2-4, wherein the screw jack motor 2-4 and the screw jack 2-3 drive the fork arm 2-1 to ascend and descend together, and the fork arm motor 2-2 drives the fork arm 2-1 to extend and retract.

The working principle of the specific embodiment is as follows: the fork arm motor 2-2 controls the extension and retraction of the fork arm 2-1, and the screw jack motor 2-4 controls the ascending and descending of the fork arm 2-1, as shown in fig. 3 and 4. When the quenching process starts, an impeller 4 of a gas quenching chamber 6 is started firstly in a vacuum state, a middle door 3 is opened, a screw jack 2-3 descends a fork arm 2-1 to a designated position, a fork arm motor 2-2 is started, the fork arm 2-1 extends to the lower part of a heating chamber workpiece 8, the fork arm 2-1 ascends and lifts the workpiece, the fork arm 2-1 retracts to the gas quenching chamber 6, the fork arm 2-1 descends to place the workpiece 8 on a material rack of the gas quenching chamber, the fork arm 2-1 retracts to an initial position, and the middle door 3 is closed to start gas quenching. Because the transfer of the workpiece is completed under vacuum and is controlled by a motor, the workpiece can be transferred quickly and accurately, and the temperature loss in the work transfer process is small.

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.
