Description

Cure apparatus

The present invention relates to a curing machine for curing a material as a curing machine.

Generally, parts such as the automobile's transmission case, engine block, cylinder head, and manifold are molded by aluminum die casting method and are impregnated to maintain the airtightness of the cast parts themselves.

This is because the fine pores generated in the die casting process of aluminum parts act as a cause of leakage of gas or liquid in the products. By infiltrating the impregnation liquid through the impregnation process and sealing by the high-temperature polymer compounding reaction, Can be prevented.

Such an impregnation process is carried out by an impregnation system, and the impregnation system fills the pores (including cracks) generated in the material (parts) by the gas or uneven cooling rate and shrinkage during the die casting process .

That is, after the impregnation step of dipping the material in the impregnation solution in the impregnation system of the impregnation system for a predetermined time, it is subjected to dehydration, washing, curing and drying steps in the dehydrating tank, washing tank, hardening tank and drying tank respectively Thereby completing the impregnation process for the material.

However, in the impregnation system according to the prior art, the drying process is performed in a separate drying tank after the material is hardened in the hardening tank. Therefore, in terms of production cost, a separate drying tank installation cost is further increased, In addition, since the material is moved from the curing tank to the drying tank and dried separately, there is a limit in that the entire process time is increased.

In addition, in the curing tank, the material is cured in a state in which the material is completely immersed in the curing liquid. Due to such a simple structure, the heat transfer is inefficient and unevenly performed. Thus, the curing efficiency is not high, The quality of the product is deteriorated and the process time is also increased to complete the entire curing.

Further, when the curing process is completed in the curing tank, the curing liquid is discarded as it is, resulting in loss of the curing liquid and heating of the curing liquid for the next curing, which is an inefficient limit in terms of cost and energy efficiency.

Here, the curing tank 500 is configured such that the material after impregnation is heated and cured by hot water. However, the material is not limited to this and is configured to be dried in the curing tank 500 by the drying means 560. For reference, as shown in the figure, the material is put into a basket 10 having a plurality of holes, and is moved by a crane to enter the hardening tank 500.

At this time, the drying unit 560 is connected to the curing tank 500 and supplies hot air to the curing tank 500 for hot-air drying when the material is hot-water-cured or hot-cured.

The drying unit 560 may include an air heater 561 connected to the hardening tank 500 and a blowing fan 562 connected to the air heater 561. The air heater 561 may be, for example, a steam boiler for supplying steam, and a steam oven for heating the air with the steam thus supplied, though not shown in the drawing, A filter can be built in to remove any foreign material involved.

The blowing fan 562 has a function of blowing air to the hardening tank 500 through the air heater 561 so as to send hot air generated by the air heater 561 to the hardening tank 500.

As an example of the operation of the curing tank 500 constructed as described above, a curing liquid is hot water-cured while rotating around a transverse axis in a state where a material is immersed in a curing liquid. At the same time, Can be blown dry. Further, after the hot water hardening is completed, the output of the blowing fan 562 is increased to blow hot air more strongly to the entire material, thereby completing the drying process.

As described above, since the drying unit 560 connected to the curing tank 500 is constructed so that the hot-air drying can be performed together with the hot water curing which is the original function in the curing tank 500, This eliminates the need for a separate drying tank installation cost and installation space, and is advantageous in that the entire process time can be reduced since there is no need to separately dry the material in the drying trough 500 in the curing tank 500.

The curing liquid circulation line is installed in the curing tank 500. The curing liquid circulation line includes a storage tank 552 disposed below the curing tank 500 and a storage tank 552 disposed below the curing tank 500. [ And a pump 554 for moving the curing liquid to the second chamber 500.

As described above, according to the present invention, a curing liquid is sprayed onto a work and a hot water curing is performed in the curing tank 500. Thus, unlike the prior art, a material is simply immersed in a curing liquid, The efficiency of the heat transfer and the uniformity of the heat transfer are improved so that the quality of the product is improved and the overall process time is also reduced.

The recovery pipe 551 is connected to a control valve 551a electrically connected to a water level sensor (not shown) of the curing tank 500 so that the curing tank 500 maintains a water level at which only part of the material is immersed in the curing liquid Can be mounted. Accordingly, the hot water hardening of the material is made by immersing in the hardening liquid in a part of the material, and the hardening liquid is ejected in the remaining exposed part of the material, so that the hardening efficiency can be increased. At this time, the drying unit 560 is also dried at a portion exposed without being immersed in the material, so that curing and drying can be performed at the same time.

Further, since the above-described curing and drying are performed while rotating around the transverse axis by the material rotating means described later, uniform and rapid curing and drying are realized with respect to the whole material portion, so that the curing and drying efficiency can be increased .

In addition, the curing liquid circulation line further includes an overflow pipe 556 connecting the storage tank 552 with a portion higher than the recovery pipe 551 in the curing tank 500, The overflow of the curing liquid can be securely and stably prevented.
