Description

Nitriding furnace convenient to charge

Technical Field

The utility model relates to the technical field of nitriding furnaces, in particular to a nitriding furnace convenient to charge.

Background

The nitriding process generally adopts a nitriding furnace to carry out nitriding heat treatment processing on a metal workpiece. However, the material frame in the existing nitriding furnace is fixed, a worker installs a workpiece on the material frame by adopting a charging sequence from bottom to top, and the nitriding furnace is high, so that the worker needs to climb when installing, the charging process is troublesome, and the charging efficiency of the nitriding furnace is low.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a nitriding furnace with convenient charging, which solves the problem that the charging process of the nitriding furnace is troublesome in the background technology.

In order to solve the technical problems, the utility model provides the following technical scheme:

the utility model provides a convenient nitriding furnace charges, includes the stove jar and installs the bell at stove jar top, install driving motor on the stove jar bottom, driving motor's output stretches into in the stove jar, and the rigid coupling has the lift lead screw, all open on the inner wall of the stove jar left and right sides has the spout, threaded connection has the material frame on the lift lead screw, equal rigid coupling has the slider on the material rest base portion left and right sides, the slider inserts in the spout.

Furthermore, the length of the lifting screw rod is greater than that of the material rack.

Furthermore, the lifting screw rod is made of refractory graphite.

Further, the inner wall surface of the chute is a smooth surface.

Compared with the prior art, the utility model has the following beneficial effects:

according to the utility model, the lifting screw rod is controlled to rotate clockwise by starting the driving motor, then the material frame is driven to lift out of the furnace tank, then a worker installs a workpiece on the material frame near the top of the furnace tank, several layers of workpieces are installed, when the worker is short of the distance, the driving motor is started again to control the lifting screw rod to rotate counterclockwise, the material frame is lowered a little, and then the workpiece is continuously installed, so that the worker does not need to climb, the loading is more convenient, the time and the labor are saved, the labor intensity of the worker is reduced, the loading efficiency of the nitriding furnace is improved, and the production efficiency is further improved.

The accompanying drawings, which are included to provide a further understanding of the utility model and are incorporated in and constitute a part of this specification, illustrate embodiments of the utility model and together with the description serve to explain the principles of the utility model and not to limit the utility model. In the drawings:

fig. 1 is a front sectional view of the present invention.

In the figure: 1. a furnace pot; 2. a furnace cover; 3. a drive motor; 4. a lifting screw rod; 5. a chute; 6. a material rack; 7. a slide block.

Detailed Description

For further explanation of the various embodiments, the drawings which form a part of the disclosure and which are incorporated in and constitute a part of this specification, illustrate embodiments and, together with the description, serve to explain the principles of operation of the embodiments, and to enable others of ordinary skill in the art to understand the various embodiments and advantages of the utility model, and, by reference to these figures, reference is made to the accompanying drawings, which are not to scale and wherein like reference numerals generally refer to like elements.

According to an embodiment of the utility model, a nitriding furnace with convenient charging is provided.

The first embodiment is as follows:

as shown in fig. 1, a nitriding furnace convenient for charging comprises a furnace tank 1 and a furnace cover 2 arranged at the top of the furnace tank 1, wherein the furnace tank 1 and the furnace cover 2 are fastened through bolts, a driving motor 3 (the driving motor 3 is general equipment in the market and is matched with a special controller) is arranged at the bottom end of the furnace tank 1, the output end of the driving motor 3 extends into the furnace tank 1 and is fixedly connected with a lifting screw rod 4, sliding grooves 5 are formed in the inner walls of the left side and the right side of the furnace tank 1, a material rack 6 is in threaded connection with the lifting screw rod 4, sliding blocks 7 are fixedly connected on the left side and the right side of the bottom of the material rack 6, and the sliding blocks 7 are inserted into the sliding grooves 5;

example two:

the length of the lifting screw rod 4 is greater than that of the material rack 6, so that after the material rack 6 is lifted out of the furnace tank 1, the bottom of the material rack 6 is still connected with the lifting screw rod 4, and when workers load materials, the stability of the material rack 6 is guaranteed;

the lifting screw rod 4 is made of refractory graphite, and the lifting screw rod 4 is made of refractory graphite due to high-temperature work in the nitriding furnace, so that the high-temperature resistance of the lifting screw rod 4 is ensured;

the inner wall surface of the sliding chute 5 is a smooth surface, so that the sliding friction force between the sliding block 7 and the sliding chute 5 is reduced;

the working principle of the utility model is as follows:

when a nitriding furnace is charged, starting the driving motor 3 to control the lifting screw rod 4 to rotate clockwise, lifting the material rack 6 out of the furnace tank 1, then installing a workpiece on the material rack 6 near the top of the furnace tank by a worker, starting the driving motor 3 to control the lifting screw rod 4 to rotate counterclockwise after the worker does not reach the lifting screw rod, lowering the material rack 6 a little, then installing the workpiece on the material rack 6, finally taking the material rack 6 into the furnace tank 1, then covering the furnace cover 2, and performing nitriding treatment;

consequently this practicality need not the staff and climbs, and it is more convenient to feed, and labour saving and time saving has reduced staff's intensity of labour, has improved the charging efficiency of nitriding furnace, and then has improved production efficiency.
