Description

Technical Field

[0001] The present invention relates to the technical field of cooling devices, and more particularly, to a device and a cooling method for rapidly cooling castings. Background Art

[0002] A casting is a metal formed object obtained by various casting methods, that is, the smelted liquid metal is injected into a pre-prepared mold by pouring, injection, suction or other casting methods. The just-cast casting is in a high-temperature state and needs to be cooled to a certain temperature before subsequent processing can be carried out. However, the cooling rate of conventional castings placed at normal temperature is slow, and the larger the volume of the casting, the slower the cooling. Therefore, a special cooling device is required.

[0003] Common casting cooling devices such as CN214517538U, a device for rapidly cooling castings in casting processing, CN219130747U, a device for rapidly cooling castings in casting processing, etc. Although such devices can cool the castings well, their operations are relatively cumbersome, and it is necessary to frequently open and close the box door to put the castings in or take them out, and multiple castings cannot be processed simultaneously. Therefore, the improvement of the cooling efficiency of the castings is limited. Therefore, a device that can cool castings in batches can be designed. Summary of the Invention

[0004] The purpose of the present invention is to provide a device and a cooling method for rapidly cooling castings, which can efficiently and batch-cool the castings.

[0005] The present invention is achieved through the following technical solutions: The device for rapidly cooling castings of the present invention includes a bottom plate, a bracket disposed above the bottom plate, an operation plate hinged to the bracket, a driving device for driving the operation plate to rotate along the bracket, a cover body covering the operation plate, a plurality of frames slidably disposed in the cover body, a gas supply device communicated with the inside of the cover body, and an exhaust device communicated with the inside of the cover body; the bracket and the driving device are respectively disposed at both ends of the operation plate, and air-permeable holes are provided on the side wall of the frame.

[0006] Further, a ring-shaped support rod is provided at the inner bottom of the frame, and both ends of the support rod are disposed outside the frame; sliding grooves are provided on both opposite sides inside the cover body, and the part of the support rod disposed outside the frame is slidably disposed in the sliding grooves.

[0007] Further, the support rod is of a hollow structure, and air inlet pipes are connected to both ends of the support rod, and the air inlet pipes are connected to the gas supply device; a plurality of air inlets are provided on the side wall of the part of the air inlet pipe disposed inside the frame.

[0008] Further, a baffle is provided on one side of the upper surface of the bottom plate close to the bracket, and the distance between the baffle and the cover body is equal to the width of the frame body.

[0009] Further, the air supply device includes a plurality of air supply pipes provided on opposite inner side walls of the cover body, and a pneumatic machine connected to the air supply pipes; the air supply pipes correspond to the air inlet pipes one by one, and the distance between adjacent air supply pipes is equal to the width of the frame body.

[0010] Further, the air supply device further includes grooves opened on opposite inner side walls of the cover body; the air supply pipes are arranged in the grooves, the length of the grooves is greater than the diameter of the air supply pipes, elastic ropes are provided on the side walls of the air supply pipes, and the elastic ropes are fixedly connected to the inner walls of the grooves; a first magnetic attraction ring is provided at the end of the air supply pipe, and a second magnetic attraction ring is provided at the end of the air inlet pipe; the first magnetic attraction ring and the second magnetic attraction ring attract each other.

[0011] Further, the driving device includes a rotating shaft provided at the end of the operation board, and a pair of telescopic cylinders respectively provided on both sides of the operation board; the cylinder body of the telescopic rod is hinged to the bottom plate, and the telescopic rod of the telescopic cylinder is hinged to the rotating shaft.

[0012] Further, the exhaust device includes an exhaust pipe provided on the upper side of one end of the cover body close to the driving device, and a negative pressure machine connected to the exhaust pipe.

[0013] The present invention also provides a cooling method based on the above device for quickly cooling castings, including the following operating steps:

[0014] (1) Start the air supply device to send normal temperature or low temperature air into the cover body, and finally discharge it from the exhaust device;

[0015] (2) When the operation board is in a horizontal state, place the just-cast high-temperature casting into the frame body, then the operator holds the support rods at both ends of the frame body, lifts the frame body and moves it to the side of the operation board far from the bracket, and clamps the support rods at both ends of the frame body in the sliding grooves;

[0016] (3) Start the driving device to raise the side of the operation board far from the bracket. Under the action of gravity, the frame body slides into the interior of the cover body, and then use the driving device to move the operation board to a horizontal position;

[0017] (4) Repeat steps (2)-(3). At this time, the sufficiently cooled frame body will slide out of the cover body and abut against the baffle. When the operation board is in a horizontal state, the operator can take out the frame body.

When a new frame is placed on the operation board and the operation board is tilted by the driving device (the side of the operation board close to the driving device rises), under the action of gravity, the frame will automatically slide into the cover body. At the same time, the casting in the frame that entered the cover body first has been fully cooled, so the frame will slide out of the cover body, and the operator can just take away this frame. In this way, not only can a large number of castings be cooled simultaneously, but also the feeding and discharging are very convenient, and real-time feeding and real-time discharging can be achieved, and there is no need to frequently perform operations such as opening and closing the box door. The automation degree of the whole process is high, and the labor intensity of workers is low. Description of the Drawings

Detailed Embodiments

[0028] Example 1

[0029] The following further explains with specific examples. As shown in the attached Figure 1 - attached Figure 8 As shown, the device for rapidly cooling castings of the invention in this embodiment includes a bottom plate 11, a bracket 12 disposed above the bottom plate 11, an operation plate 21 hinged to the bracket 12, a driving device 13 for driving the operation plate 21 to rotate along the bracket 12, a cover 22 covering the operation plate 21, a plurality of frames 31 slidably disposed in the cover 22, a gas supply device communicated with the inside of the cover 22, and an exhaust device communicated with the inside of the cover 22; the bracket 12 and the driving device 13 are respectively disposed at both ends of the operation plate 21, and air permeable holes 32 are formed in the side wall of the frame 31. Specifically, when in use, the frame 31 containing the high-temperature casting is placed in the cover 22, and the casting is blown and cooled by the gas supply device. When a new frame 31 is placed on the operation plate 21 and the operation plate 21 is driven by the driving device 13 to tilt (the side of the operation plate 21 close to the driving device 13 rises), under the action of gravity, the frame 31 will automatically slide into the cover 22. At the same time, the casting in the frame 31 that first entered the cover 22 has been sufficiently cooled, so the frame 31 will slide out of the cover 22, and the operator can take away the frame 31. In this way, not only can a large number of castings be cooled simultaneously, but also the feeding and discharging are very convenient, and real-time feeding and real-time discharging can be achieved, and there is no need to frequently perform operations such as opening and closing the box door. The automation degree of the whole process is high, and the labor intensity of workers is low.

[0030] In this embodiment, a ring-shaped support rod 33 is provided at the inner bottom of the frame 31, and both ends of the support rod 33 are disposed outside the frame 31; sliding grooves 23 are formed on both opposite sides inside the cover 22, and the part of the support rod 33 disposed outside the frame 31 is slidably disposed in the sliding grooves 23. The support rod 33 is a hollow structure, and air inlet pipes 35 are connected to both ends of the support rod 33, and the air inlet pipes 35 are connected to the gas supply device; a plurality of air inlets 34 are formed in the side wall of the part of the air inlet pipe 35 disposed inside the frame 31. Specifically, the low-temperature or normal-temperature air generated by the gas supply device is directly sent into the air inlet pipe 35 and discharged through the air inlets 34 on the side wall of the air inlet pipe 35. In this way, the low-temperature or normal-temperature air can directly blow on the casting, and the casting can be cooled better and faster.

[0031] On the upper surface of the bottom plate 11 in this embodiment, a baffle is provided on one side close to the bracket 12, and the distance between the baffle and the cover body 22 is equal to the width of the frame body 31. The air supply device includes a plurality of air supply pipes 41 provided on the opposite inner side walls inside the cover body 22, and an air compressor 42 connected to the air supply pipes 41; the air supply pipes 41 correspond to the air inlet pipes 35 one by one, and the distance between adjacent air supply pipes 41 is equal to the width of the frame body 31. Specifically, the distance that the frame body 31 moves each time in the cover body 22 is the same (i.e., the width of the frame body 31). Therefore, after each movement, the air supply pipe 41 can accurately align with the air inlet pipe 35 and supply air.

[0032] The air supply device in this embodiment further includes grooves 24 opened on the opposite inner side walls inside the cover body 22; the air supply pipes 41 are arranged in the grooves 24, the length of the grooves 24 is greater than the diameter of the air supply pipes 41, elastic ropes 43 are provided on the side walls of the air supply pipes 41, and the elastic ropes 43 are fixedly connected to the inner walls of the grooves 24; a first magnetic attraction ring is provided at the end of the air supply pipe 41, and a second magnetic attraction ring is provided at the end of the air inlet pipe 35; the first magnetic attraction ring and the second magnetic attraction ring attract each other. Specifically, the grooves 24 are arranged in the sliding grooves 23, and the air supply pipes 41 are fixed by the elastic ropes 43, so that the air supply pipes 41 can move within a certain range (the air supply pipes 41 are flexible pipes), and by providing a first magnetic attraction ring at the end of the air supply pipe 41 and a second magnetic attraction ring at the end of the air inlet pipe 35, the air inlet pipe 35 and the air supply pipe 41 can be docked faster and more accurately through the attraction between the first magnetic attraction ring and the second magnetic attraction ring, and the air leakage can also be effectively reduced.

[0033] The driving device 13 in this embodiment includes a rotating shaft 131 provided at the end of the operation board 21, and a pair of telescopic cylinders 132 respectively provided on both sides of the operation board 21; the cylinder bodies of the telescopic rods are hinged to the bottom plate 11, and the telescopic rods of the telescopic cylinders 132 are hinged to the rotating shaft 131. Specifically, by synchronously moving a pair of telescopic cylinders 132, the operation board 21 can be driven to rotate around the bracket 12, and the telescopic cylinders 132 can be pneumatic, electric or hydraulic.

[0034] The exhaust device in this embodiment includes an exhaust pipe 25 provided on the upper side of one end of the cover body 22 close to the driving device 13, and a negative pressure machine connected to the exhaust pipe 25. Specifically, through the negative pressure machine and the exhaust pipe 25, the high-temperature air can be better discharged to avoid affecting the surrounding operators.
