 As shown in FIG. 1 to FIG. 3, the cooling device 1 according to the present invention includes a cooling chamber 2a as a component cooling section for cooling the forged coarse material 4. The cooling air is circulated between the water cooling device (water tank container 7, spraying device 8, etc.) as an air cooling unit for cooling the cooling air by water cooling, and the component cooling unit and the air cooling unit. And a cooling air supply device 6.

 Each of these devices is packaged in a case 12 and configured as a unit.

 1 and 2 show an example of the configuration of the cooling device 1 described above. The sealed container 2 is configured in a box shape (tunnel type) having a predetermined transport distance, and the inner space is a cooling chamber. Configured as 2a. One end of the sealed container 2 is configured as a delivery port 21, and the other end is configured as a delivery port 22. For example, forged raw material 4 ····· such as aluminum rough material after heat treatment is fed into the inlet 21, and is transferred through the cooling chamber 2 a by the transfer device 5, and sent out from the outlet 22. Being done! /

 [0026] In addition, the transport device 5 has a plurality of forged rough materials 4 · 4 ··· placed thereon, and sequentially passes the forged rough materials 4 · 4 · · · from the inlet 21 to the outlet 22 It is configured to transport.

 This transport device 5 can be configured as a motor-driven automatic transport device, or it can be configured such that the forged rough material 4, 4,. It ’s not particularly limited.

 [0027] Further, the inlet 21 is provided with double opening / closing doors 21a '21b, and the double opening / closing doors 21a' 21b allow the cooling chamber 2a to communicate with the outside through the inlet 21. It is designed to be blocked.

 The delivery port 22 is provided with an opening / closing door 22a, and the opening / closing door 22a blocks communication between the cooling chamber 2a and the outside via the delivery port 22.

 The doors 21a 'and 21b are opened only when the forged rough material 4 is fed, and the doors 22b are opened only when the forged rough material 4 is delivered. Make sure that the rejection chamber 2a is sealed and prevents the leakage of hot air to the outside!

[0028] Further, in the cooling chamber 2a, the temperature on the inlet 21 side where the forged rough material 4 in a high temperature state is fed Since the temperature becomes particularly high, the opening / closing doors 21a '21b of the inlet 21 have a double structure. As a result, the high-temperature hot air generated by the four forged rough materials does not leak to the outside!

 Specifically, when the forged rough material 4 is fed, only the front door 21a is opened with the rear door 21b closed, and the forged rough material 4 is opened. Is sent between the two open / close doors 21a '21b, and when the open / close door 21a is closed, the open / close door 21b is opened. In this way, since the hot air in the cooling chamber 2a inside the rear opening / closing door 21b does not leak directly to the outside, the amount of heat leaking to the outside can be reduced.

 In addition, the operation of the double doors 21a '21b is carried out by operating both doors 21a' 21b with the link mechanism 23 and depressing the pedal 24. The doors 21a '21b can be opened and closed easily and reliably.

 The open / close doors 21a '21b' 22a may be configured to open / close by motor drive based on button operations or the like.

[0029] Further, the airtight container 2 discharges the cooling air supplied from the cooling air supply device 6 into the cooling chamber 2a and the cooling air in the cooling chamber 2a. An outlet 2c is provided!

 Further, the blowing port 2b is provided at the downstream side in the direction in which the forged rough material 4 is transferred in the cooling chamber 2a, and is provided inside the cooling chamber 2a in the vicinity of the opening / closing door 22a.

 On the other hand, the discharge port 2c is a position on the upstream side in the direction in which the forged rough material 4 is transferred in the cooling chamber 2a, and is close to the open / close door 21b in the vicinity of the open / close door 21b. On the other hand, it is provided inside the cooling chamber 2a, that is, at a position opposite to the outside opening / closing door 21a.

[0030] The air inlet 2b is communicated with the cooling air supply device 6 via a ventilation duct or the like, and the cooling air supplied from the cooling air supply device 6 is supplied to the air inlet. From 2b, it is blown into the cooling chamber 2a.

The discharge port 2c communicates with the upper space 7a of the water tank container 7 through a ventilation duct or the like. The cooling air after cooling the forged rough material 4 is discharged from the discharge port 2c to the upper space 7a.

 [0031] Further, in the water tank container 7, the upper space 7a is provided with a spraying device 8 for spraying water into the upper space 7a, thereby cooling the water discharged from the cooling chamber 2a. Reduce the air temperature and increase the humidity.

 The spraying device 8 may have a simple configuration including a plurality of extremely small nozzles as long as water vapor is sprayed, and the specific configuration is not particularly limited.

 In the water tank container 7, a gas-liquid contact filler 10 is provided at a substantially central portion in the vertical direction. The gas-liquid contact filler 10 causes the air in the water tank container 7 to be sprayed. The contact area of the water sprayed from the device 8 is increased to improve the absorption rate of water with respect to the air (in other words, the absorption rate of air with respect to water). This improves the cooling efficiency of the cooling air with water.

 As for the gas-liquid contact packing 10, for example, a general configuration using a gas-liquid contact plate in which a metal flat plate and a metal net are bonded, or a gas contact plate made of a polymer material is used. The configuration used is conceivable, and the specific configuration is not particularly limited.

 Further, in the water tank container 7, liquid water is always stored in the lower space 7 b, and this water is pumped up by the pump 11 and supplied to the spraying device 8. However, the spraying device 8 sprays the inside of the upper space 7a. In this way, water for cooling the cooling air is circulated and used in the water tank container 7.

 In this way, the water tank 7, the spray device 8, the pump 11, the gas-liquid contact filler 10, and the like constitute an air cooling unit that cools the cooling air by water cooling. Note that the water in the lower space 7b is cooled by an external cooling device (not shown), and the temperature of the water sprayed from the spraying device 8 is always set to a predetermined temperature or lower.

In addition, a demister 9 is interposed between the gas-liquid contact filler 10 and the cooling air supply device 6, and the air in the upper space 7 a is mist-removed by the demister 9. Then, the air is sucked into the cooling air supply device 6. Then, the air after the mist is removed by the demister 9 is supplied as cooling air from the inlet 2b into the cooling chamber 2a.

 In the demister 9, the mist is removed so that the humidity of the cooling air blown into the cooling chamber 2a from the blow-in port 2b is less than 100%.

 For this mist removal control by the demister 9, a humidity sensor is installed near the inlet 2b, and the mist removal function part of the demister 9 is controlled by the controller so that the detected value of the humidity sensor is less than 100%. The specific configuration is not particularly limited.

[0035] As described above, the humidity of the cooling air is set to less than 100% by the demister 9 for the following reason.

 That is, the forged raw material 4 just transferred to the vicinity of the inlet 2b and sent out from the cooling chamber 2a has dropped in temperature from about 60 degrees to less than 100 degrees. If air is blown in, the water in the cooling air will not evaporate but will form water droplets and will gradually stay in the sealed container 2. It will be complicated.

 In addition, when the moisture adhering to the surface of the forged rough material 4 is saturated to form water droplets, if there is a forged core, water will be swallowed into the forged core and the forged core will be altered and deteriorated. In the core removal step in the post-process, the forged core partially remains in the forged coarse material 4 and may become a defective product.

 For these reasons, as described above, by setting the humidity of the cooling air to less than 100% by the demister 9, it becomes possible to avoid the problem.

[0036] In the above configuration, the cooling air blown into the cooling chamber 2a from the blowing port 2b by the cooling air supply device 6 cools the forged rough material 4 ··· 4 The gas is discharged from the discharge port 2c to the upper space 7a, and is cooled by spraying water by the spray device 8 in the upper space 7a. Thereafter, the air is sucked by the cooling air supply device 6 through the demister 9 and then blown again from the blow port 2b.

In this way, the cooling air in the cooling device 1 does not leak outside, the cooling chamber 2a, the upper part Since it is circulated in the space 7a, work environment inside and outside the factory can be prevented.

[0037] Further, in the above configuration, the opening / closing operation of each opening / closing door 21a'21b'22a and the transfer operation of the forged rough material 4 · 4 ··· by the transfer device 5 are interlocked with the operation of the pedal 24. As a little.

 For example, when the pedal 24 is depressed, the open / close door 21a outside the inlet 21 is first opened, and the forged rough material 4 in a high temperature state is fed. When the outer door 21a is opened, the inner door 21b is closed. Then, when the depression of the pedal 24 is released, the outer door 21a is closed and the inner door 21b is opened, and the conveying device 5 is operated so that each forged rough material 4 The forged raw material 4 is transferred only for the width of one piece. At this time, the opening / closing door 22a of the delivery port 22 is opened, and the cooled forged rough material 4 can be taken out.

 [0038] In this way, the forged rough material 4 · · · · is sequentially cooled by feeding the cooled forged rough material 4 while feeding the forged rough material 4 in a high temperature state. be able to. Further, in this case, since the work can be performed with only one operation of the pedal 24, the worker can easily and reliably carry out the work.

 In addition to the operation of the pedal 24 as described above, the opening / closing operation of the open / close doors 21a '21b' 22a and the transfer operation of the forged rough material 4 · 4 ··· by the transfer device 5 are performed by the control device. It is good also as making it implement automatically. Further, the detailed configuration for linking each device can be implemented by a known technique and is not particularly limited.

 [0039] As described above, the cooling device 1 according to the present invention includes the cooling chamber 2a that accommodates the high-temperature parts, and the transport for transferring the forged rough material 4 · 4 ··· that is the high-temperature parts in the cooling chamber 2a. The device 5 is connected to the cooling air supply device 6 for blowing cooling air into the cooling chamber 2a, and the cooling chamber 2a communicates with the upper space 7a, and water is applied to the lower space 7b to form a water tank. A water tank container 7 and a spraying device 8 for spraying water into the upper space 7a. The cooling air supply device 6 supplies cooling air between the cooling chamber 2a and the water tank container 7. And the cooling air in the water tank container 7 is cooled by the spraying device 8.

With this configuration, leakage of hot air generated from high-temperature parts to the outside of the cooling chamber 2a is suppressed. In addition, since the cooling air is not discharged to the outside of the cooling chamber 2a, it is possible to prevent the work environment from deteriorating without raising the ambient temperature in the factory. In addition, it is possible to prevent scattering of dust generated from high-temperature parts.

 [0040] Further, in the water tank container 7, the cooling air is cooled by the spray of water from the spraying device 8, so that the cooling capacity in the cooling chamber 2a can be improved. For example, 30 minutes after delivery, it is possible to cool high-temperature parts to 400 degrees force and 60 degrees or less, and it is possible to achieve a cooling speed four times that of the conventional one. In addition, this reduction in cooling time can improve production efficiency.

 Further, by adopting a configuration in which the cooling air is circulated in this way, the cooling device 1 can be made into a unit and space-saving. In addition, environmental deterioration inside and outside the factory can be prevented because cooling air is not discharged to the outside.

 [0041] Further, a gas-liquid contact filler 10 is installed in the water tank container 7.

 With this configuration, the cooling efficiency of the cooling air with water is improved, and the cooling capacity in the cooling chamber 2a can be improved.

 [0042] Further, at one end of the closed container 2 constituting the cooling chamber 2a, an inlet 21 for feeding the forged rough material 4 ····, which is the high-temperature part, is configured, and the cooling The other end of the closed container 2 constituting the chamber 2a is provided with a delivery port 22 for delivering the forged rough material 4 · 4 ···, and the delivery port 21 includes the delivery port 21. A first opening / closing door 21a that closes the opening of the first opening / closing door 21a and a second opening / closing door 21b located inside the cooling chamber 2a with respect to the first opening / closing door 21a. The opening / closing door 21b is closed when it is opened, and the delivery port 22 is provided with a third opening / closing door 22a that closes the opening of the delivery port 22. At other times, the cooling chamber 2a is configured as a closed space.

 With this configuration, it is possible to suppress the leakage of hot air in the cooling chamber 2a to the outside, and in particular, on the inlet 21 side where the temperature is high, the heat inside the second opening / closing door 21b on the back side is higher. Since Qi does not leak directly to the outside, the amount of heat leaking to the outside can be reduced.

[0043] The cooling air supplied from the cooling air supply device 6 is provided in the cooling chamber 2a. Are provided with an inlet 2b for injecting air into the cooling chamber 2a and an outlet 2c for discharging the cooling air of the cooling chamber 2a. Is provided in the cooling chamber 2a, in the vicinity of the third opening / closing door 22a, and the discharge port 2c is provided in the cooling chamber 2a. The water tank container 7 and the cooling air supply device 6 are provided on the upstream side in the transport direction and in the cooling chamber 2a in the vicinity of the second opening / closing door 21b. A demister 9 is interposed in between, and in the demister 9, the mist removal of the cooling air is performed, and the humidity of the cooling air blown into the cooling chamber 2a is reduced to less than 100%. Yes.

 With this configuration, water droplet formation in the cooling chamber 2a can be prevented, and a simple device configuration that does not require a discharge mechanism can be achieved. Even when a forged core is present, water can be produced in the forged core. It is possible to prevent stagnation and to prevent generation of defective products due to the stagnation of water.

[0044] Further, as described above, the forged rough material 4 · 4 ··· which is a high-temperature part is sequentially transferred in the cooling chamber 2a and from the downstream side of the flow of the forged rough material 4 · 4 ····. A method for cooling a high-temperature component in which cooling air is blown upstream, wherein the cooling air is cooled by water spray outside the cooling chamber 2a, and then the humidity is less than 100% by the demister 9 After that, it is blown into the cooling chamber 2a and recycled. In this cooling method, the cooling air can be circulated to save the unit and save space. In addition, the cooling air is not discharged to the outside, and environmental deterioration inside and outside the factory can be prevented.

 Moreover, cooling efficiency can be improved by cooling the cooling air by water spray. In addition, the mist removal of the cooling air by the demister 9 prevents water droplets from being formed in the cooling chamber 2a, and the generation of defective products due to this water penetration can be prevented.

[0045] In the above-described embodiment, the force given as an example in which the conveying device 5 is driven by the motor drive in the cooling chamber 2a of the forged rough material 4 ····· As a configuration using an actuator.

In addition, for the inlet 21 of the cooling chamber 2a, a double door configuration is used for the door 21a '21b. If the leakage of heat from the airtight container 2 to the outside is within an allowable range, one door is opened. It is good also as an open state, without providing only or using a door. In this configuration case

, Force that will cause a slight amount of heat leakage during the feeding of forged raw materials 4.4 .. When some amount of heat leakage is acceptable, a single door or open configuration will reduce equipment costs. It is also beneficial.
