2. The other heat treatment temperatures can be switched after the current production work piece is removed, and the long heating or cooling time is needed to realize, so that the utilization rate of equipment is seriously affected.
Disclosure of utility model
The utility model aims to provide a multi-layer heat treatment furnace, which solves the problems in the prior art, and is provided with a plurality of independent temperature-control hearths, so that the heat treatment process realizes the functions of production of the same part at different temperatures, production of different parts at different temperatures and rapid temperature switching of the hearths, and the equipment utilization rate and the production efficiency are improved.
In order to achieve the above object, the present utility model provides the following solutions:
The utility model provides a multilayer heat treatment furnace which comprises at least two hearths which are transversely arranged, wherein a heating system is arranged in each hearth and is used for independently controlling the temperature of each hearth, and a plurality of supporting beams are also arranged in each hearth from top to bottom.
Preferably, the front side of each hearth is provided with an oven door.
Preferably, the furnace body is further provided with more than two hearths spaced in the furnace body.
Preferably, a plurality of strip-shaped gaps are formed in the supporting beam along the feeding and discharging direction, and charge forks of the skip can pass through the supporting beam up and down through the strip-shaped gaps.
Preferably, a circulating fan is arranged at the top of each hearth.
Compared with the prior art, the utility model has the following beneficial technical effects:
According to the multi-layer heat treatment furnace provided by the utility model, the production of the same part at different temperatures at different stages, the production of different parts at different temperatures and the rapid temperature switching function of the hearth are realized in the heat treatment process through different temperature control of a plurality of hearths, and the equipment utilization rate and the production efficiency are improved. The method has the advantages of reliable performance, flexible process and various purposes, and has wide market space.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The utility model aims to provide a multi-layer heat treatment furnace, which solves the problems in the prior art.
In order that the above-recited objects, features and advantages of the present utility model will become more readily apparent, a more particular description of the utility model will be rendered by reference to the appended drawings and appended detailed description.
1-2, The multi-layer heat treatment furnace comprises at least two hearths 1 which are transversely arranged, wherein a heating system 2 is arranged in each hearth 1, the heating system 2 is used for independently controlling the temperature of each hearth 1, and a plurality of supporting beams 4 are also arranged in each hearth 1 from top to bottom; the front side of each hearth 1 is provided with an oven door 6.
The furnace body 10 is further included, and at least two hearths 1 are spaced in the furnace body 10.
In this embodiment, a plurality of strip gaps 11 are provided on the support beam 4 along the feeding and discharging direction, and the fork 8 of the skip can pass through the support beam 4 up and down through the strip gaps.
In this embodiment, a circulation fan 5 is disposed at the top of each furnace 1.
The multi-layer heat treatment furnace in the embodiment is fed and discharged through a skip, and the feeding steps are as follows:
Step 1: the material 3 is placed on a material fork of the skip car and driven by a skip car travelling device 9 to travel to one of the target hearths 1;
step 2: the skip lifting system 7 lifts the material fork and the material 3 to a target layer, and the upper edge of the material fork 8 (namely the lower edge of the material 3) is higher than the support beam 4 in the furnace;
step 3: the furnace door 6 of the target layer is opened, and the material fork 8 forks the material 3 into the furnace;
Step 4: the skip lifting system 7 descends to a certain height below the supporting beam 4 in the furnace, and as the material fork 8 can pass through the strip-shaped gap on the supporting beam 4, the material 3 is left on the supporting beam 4, and the material fork can be pulled out from the hearth 1;
step 5: the empty fork of the fork moves out of the hearth 1;
step 6: and closing the furnace door 6 to finish furnace charging.
The above steps are the furnace loading action steps, when the furnace is discharged, the position of the material fork is lower than that of the supporting beam 4, the material fork enters the furnace chamber 1, and then the material fork is lifted to lift the material 3 on the supporting beam 4 out of the furnace chamber 1.
The principles and embodiments of the present utility model have been described with reference to specific examples, which are provided to facilitate understanding of the method and core ideas of the present utility model; also, it is within the scope of the present utility model to be modified by those of ordinary skill in the art in light of the present teachings. In summary, the present description should not be construed as limiting the utility model.
