Description

Technical Field

[0001] The utility model belongs to the technical field of casting cooling, and in particular relates to a casting rapid cooling device. Background Art

[0002] The liquid metal is poured into a mold cavity with a shape and size that matches the part, and waits for it to cool and solidify to obtain a blank or part called a casting. During the casting process, the temperature of the blank casting just produced from the production line is generally above 700°C, so the casting must be cooled before entering the next link. There are generally two ways to cool castings: air cooling and water cooling. Air cooling generally sets a fan above the casting to blow air to the casting transported on the conveyor belt. It can only blow air in a fixed direction of the casting, and the cooling efficiency is low, but it will not cause damage to the casting. The cooling efficiency of water cooling is higher, but there is a certain probability that the high-temperature casting will be directly placed in the cooling water, which will cause cracks on the surface of the casting, affecting the success rate of the casting. Utility Model Content

[0003] In view of the above problems, the purpose of the present invention is to provide a device for rapid cooling of castings to solve the problems raised in the above background technology.

[0005] The beneficial effect of the utility model is that when the casting is placed on the turntable, the casting is driven to rotate as the motor runs, which can change the position of the casting toward the wind guide cover, and convey air-cooled gas with coolant to the casting, so that the casting can be cooled in multiple directions, which not only does not affect the quality of the casting, but also can speed up the cooling speed of the casting.

[0006] In order to speed up the cooling of the casting:

[0007] As a further improvement of the above technical solution: the turntable includes a bottom plate arranged on the output shaft of the motor and a top plate connected to the top of the bottom plate through a support column, and a plurality of ventilation holes are evenly opened on the top plate.

[0008] The beneficial effect of this improvement is that the castings are evenly placed on the edge of the top plate, the connection lines between all the castings are circular, the castings are cooled by blowing air through the air guide cover, and the ventilation holes can ensure ventilation on both sides of the castings, thereby accelerating the cooling speed.

[0009] To remove heat from the bottom of the casting:

[0010] As a further improvement of the above technical solution: an air distribution duct is arranged below the air guide duct, and one end of the air distribution duct away from the air guide duct passes through the support frame and extends between the bottom plate and the top plate.

[0011] The beneficial effect of this improvement is that by arranging a branch air duct at the lower part of the support frame, air can be blown between the bottom plate and the top plate, thereby taking away the heat at the bottom of the casting.

[0012] To be able to blow the gas carrying the coolant onto the casting:

[0013] As a further improvement of the above technical solution: the infusion tube is arranged in a semicircular arc shape.

[0015] In order to further improve the cooling efficiency of castings:

[0016] As a further improvement of the above technical solution: a condenser is connected to the middle of the ventilation pipe, and a gas condensation pipe is connected to the inside of the condenser for condensing the gas transported by the fan.

[0017] The beneficial effect of this improvement is that the setting of the condenser can condense the gas delivered by the fan, thereby reducing the temperature of the air-cooled gas and achieving the effect of the first step of cooling the casting.

[0018] In order to avoid accidental injury to personnel by heated gases caused by castings:

[0019] As a further improvement of the above technical solution: a semi-circular air guide plate is arranged on one side of the base away from the support frame through a support rod, air guide channels are symmetrically arranged at both ends of the air guide plate, and a water tank is arranged below the air guide channel.

[0020] The beneficial effect of this improvement is that when the air guide hood blows the air-cooled gas toward the casting, it takes away the heat from the casting, causing the temperature of the gas to rise. The air guide plate can enclose and guide the gas with increased temperature, so that it is guided along the air guide channel to the water tank, thereby preventing the high-temperature gas from accidentally injuring the staff.

[0021] In order to enable the air guide plate to enclose and guide the gas blown out of the air guide hood:

[0022] As a further improvement of the above technical solution: the position of the air guide cover is opposite to the middle of the air guide plate.

[0023] The beneficial effect of this improvement is that the horizontal position of the air guide cover is directly opposite to the middle of the air guide plate, so that the gas blown out of the air guide cover can be enclosed and guided. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.

[0030] like Figure 1-4As shown, a casting rapid cooling device comprises a base 1, a turntable 3 arranged on the top of the base 1 through a motor 2, and a cooling device arranged on one side of the base 1 through a support frame 4, wherein the cooling device comprises a fan 5 arranged on the outside of the support frame 4, an air duct 7 arranged on the side of the support frame 4 away from the turntable 3 and connected to the fan 5 through a ventilation pipe 6, an air duct 8 penetrating the upper part of the support frame 4 and connected to the air duct 7, a liquid storage tank 9 arranged at the bottom of the support frame 4, a liquid infusion pipe 11 arranged on the upper part of the liquid duct 8 and connected to the liquid storage tank 9 through a liquid extraction pipe 10, and a plurality of spray heads 12 evenly arranged on the inner side of the liquid infusion pipe 11. When the casting is placed on the turntable 3, as the motor 2 runs, the casting is driven to rotate, which can change the casting. Towards the position of the wind guide hood 8, air-cooled gas with coolant is transported to the casting, so that the casting can be cooled in multiple directions, which will not only not affect the quality of the casting, but also speed up the cooling of the casting. The turntable 3 includes a bottom plate 13 arranged on the output shaft of the motor 2 and a top plate 15 connected to the top of the bottom plate 13 through a support column 14. The top plate 15 is evenly provided with a plurality of ventilation holes 16 to evenly place the castings at the edge of the top plate 15. The connecting lines between all the castings are circular. The castings are cooled by blowing air through the wind guide hood 8. The ventilation holes 16 can ensure ventilation on the upper and lower sides of the casting, thereby speeding up the cooling. A branch air duct 17 is arranged below the air guide duct 7, and the branch air duct 17 is away from the air guide duct 7. One end of the support frame 4 extends through the bottom plate 13 and the top plate 15. By setting a branch air duct 17 at the lower part of the support frame 4, air can be blown between the bottom plate 13 and the top plate 15, so as to take away the heat from the bottom of the casting. The infusion pipe 11 is set in a semicircular arc shape, and the spray heads 12 are evenly distributed on the infusion pipe 11. When the gas delivered by the fan 5 passes through the wind guide cover 8, the coolant sprayed by the spray head 12 is blown onto the casting. The middle part of the ventilation pipe 6 is connected to a condenser 18, and the inside of the condenser 18 is connected to a gas condensation pipe for condensing the gas delivered by the fan 5. The setting of the condenser 18 can condense the gas delivered by the fan 5, so as to reduce the temperature of the air-cooled gas, thereby achieving In order to achieve the effect of the first step of cooling the casting, a semicircular air guide plate 20 is provided on the side of the base 1 away from the support frame 4 through the support rod 19, and air guide channels 21 are symmetrically provided at both ends of the air guide plate 20. A water tank 22 is provided below the air guide channel 21. When the air guide hood 8 blows the air-cooled gas to the casting, it takes away the heat on the casting, so that the temperature of the gas increases. The air guide plate 20 can enclose and guide the gas after the temperature increases, so that it is guided along the air guide channel 21 to the water tank 22, thereby preventing the high-temperature gas from accidentally injuring the staff. The position of the air guide hood 8 is opposite to the middle of the air guide plate 20, and the horizontal position of the air guide hood 8 is opposite to the middle of the air guide plate 20, so that the gas blown out of the air guide hood 8 can be enclosed and guided.

[0031] The working principle and use process of the utility model are as follows: when using the device, the casting is evenly placed on the edge of the top plate 15. As the motor 2 runs, the casting is driven to rotate, which can change the position of the casting toward the wind guide cover 8. The fan 5 and the condenser 18 are turned on. The setting of the condenser 18 can condense the gas transported by the fan 5, so as to reduce the temperature of the air-cooled gas. The air-cooled gas is guided to the wind guide cover 8 and the air distribution pipe 17 along the ventilation pipe 6 and the air guide pipe 7. At the same time, the liquid supply pump of the liquid storage tank 9 is turned on to extract the coolant in the liquid storage tank 9 along the liquid extraction pipe 10. It is sprayed along the infusion pipe 11 and the spray head 12. When the air-cooled gas is blown out along the wind guide cover 8, it carries the coolant and blows onto the casting, taking away the heat on the casting, so that the temperature of the gas increases. The wind guide plate 20 can enclose and guide the gas with increased temperature, so that it is guided along the wind guide channel 21 to the water tank 22, thereby preventing the high-temperature gas from accidentally injuring the staff. The air distribution duct 17 blows the air-cooled gas to between the top plate 15 and the bottom plate 13, taking away the heat dissipated from the bottom of the casting along the ventilation holes 16, thereby accelerating the cooling speed of the casting.
