DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic heat treatment system (apparatus and method) for automatically performing a desired heat treatment on each component (member to be heat-treated) after forming such as forging.

[0002]

2. Description of the Related Art Generally, various heat treatments are performed on a part formed by forging or the like in order to remove internal stress generated during forming or processing and to increase hardness. For example, taking the case of forging as an example, after heating, heat treatment such as quenching, normalizing, or annealing with water or oil is performed singly or sequentially in plural times.

Conventionally, such a heat treatment is performed by using a heat-resistant basket (in this specification, a basket of various forms capable of accommodating a member to be heat-treated) when a part is relatively small. The basket is supplied to a plurality of desired heat treatment means (for example, a heating furnace or a quenching water tank) by a worker using a forklift or the like. Desired heat treatment is applied.

[0004]

However, when there are many types of members to be heat-treated that require different heat treatments, in the case of the above-described heat treatment system, each basket containing the members to be heat-treated is identified by some kind. A mark must be provided, and this identification mark must be stored by the operator, and the necessary heat treatment must be performed for each basket for a predetermined time. In particular, when a plurality of heat treatments are sequentially performed on each basket, while the baskets intersect in the processing steps, the operator memorizes or writes down the identification mark attached to each basket, and the necessary information is required for each basket. It must be selectively supplied to the heat treatment means sequentially or taken out immediately after the treatment. Therefore, in order to perform a series of heat treatments on each basket accurately as required, the operation is very complicated and nervous for the operator.

Further, in general, it takes a considerable amount of time for the treatment in each heat treatment means, and since the time required in each heat treatment means differs, it is necessary to temporarily store each basket for time adjustment. Since there are many cases in which this does not occur, it becomes more difficult for the worker to memorize and the work becomes complicated.

Further, as described above, in the case where members subjected to different heat treatment steps are sequentially applied while being time-adjusted by the respective heat treatment means by the operation of the operator, the processing efficiency of the entire heat treatment equipment is limited. However, it was not possible to treat a large number of different types of heat-treated members which were mass-produced and continuously conveyed by a conveyor or the like.

The present invention has been made in view of such circumstances, and has as its object to provide a heat treatment system (heat treatment equipment and heat treatment method) capable of performing a heat treatment operation accurately and mechanically.

When the heat treatment means to be supplied by the information from the apparatus is currently being processed, instead of supplying the heat treatment means, the basket 7 is temporarily put on standby in the vacant stock yard 3, and the heat treatment means When the information that the vacancy is available is obtained, the basket 7 waiting at the stock yard 3 is supplied to the target heat treatment means. When taking out the waiting basket 7 from the stock yard 3 by the loading mechanism 2E, the contents of the heat treatment are checked by the heat treatment data reading device 2B mounted on the charge car 2, and then the corresponding heat treatment means is checked. Supply. Therefore, even if the temporarily waiting basket 7 is artificially changed to another position in the stockyard 3, it is not erroneously heat-treated.

When one of the baskets 7 is being heat-treated in the corresponding heat-treating means, or is in a standby state in the stock yard 3, the charge car 2 is engaged in transporting another basket 7 for heat-treatment. And
The charge car 2 having only one is always used effectively.
In other words, the charge car 2 is located in the heat treatment means 1A to 1K and the stock yard 3, and further, the basket transfer portion 24
Is used to effectively perform parallel processing on all the baskets 7 existing in.

When the heat treatment of one basket 7 by a certain heat treatment means is completed, the basket 7 is mounted on the charge car 2 by the mounting mechanism 2E, transported to the next heat treatment means to be processed and discharged there.

When the processing of one basket in the water shower device 1D or the normalizing cooling device 1C, which is the final heat treatment step, is completed, those baskets are discharged to the chain conveyor 4 side.
Is transferred to the shot blasting device 9, and the heat-treated member in the basket 7 that has been subjected to the heat treatment is paid out by the shot blasting device 9.

The empty basket 7 is conveyed by the chain conveyor 5 to the above-described heat treatment data forming device 6, where the basket is subjected to the above-mentioned treatment, again contributing to a series of heat treatments.

In the above embodiment, the charge car 2 is configured so as not to be conveyed to the shot blasting device 9. However, when the processing capacity of the charge car 2 is higher than the processing capacity of the heat treatment means or the like. It is also possible to omit the chain conveyor 5 and convey it by the charge car 2.
