Description

TECHNICAL FIELD

[0001] The utility model relates to cast steel piece processing related technical field especially, relates to a cast steel piece automatic annealing device. BACKGROUND

[0002] Cast steel piece annealing is heated to appropriate temperature, keeps for a certain period of time, and then cooling heat treatment process, can be subdivided into complete annealing, incomplete annealing, spheroidizing annealing, stress relief annealing and multiple types.

[0003] The existing cast steel piece annealing cooling is mostly water cooling, although water cooling technology can make cast steel piece rapidly cool down in the annealing process, can significantly shorten the annealing period, but because of the fast water cooling speed, the surface and inside of cast steel piece form greater temperature difference, can lead to cast steel piece deformation even cracking, to a certain extent influence finished product quality. UTILITY MODEL CONTENT

[0004] The utility model discloses a cast steel piece automatic annealing device to solve the technical problems in the prior art.

[0005] In order to realize the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] A cast steel piece automatic annealing device includes a frame, two groups of roller bodies are rotatably connected to the frame, a motor is installed at one end of the frame, the motor is connected to one group of roller bodies, a heating assembly, a box one and a box two are connected to the frame, the box one, the box two and the heating assembly are communicated, a fan is installed on the box one, a pipe group one is connected to one end of the fan, the pipe group one penetrates the box one, a water tank is connected to the frame, a pump body is installed at one end of the water tank, the pump body is communicated with the water tank at one end, a pipe group two is connected to one end of the pump body, the pipe group two penetrates the box two, and a plurality of nozzles are connected to one end of the pipe group two.

[0007] Preferably, the pipe group one end and the other end are connected with the shell, and a plurality of hole bodies are formed in one end of the two groups of shells.

[0008] Preferably, a water outlet valve is connected to one end of the water tank.

[0009] Preferably, a water inlet valve is connected to one end of the water tank.

[0010] Preferably, a plurality of port bodies are connected to one end and the other end of the box one.

[0011] Preferably, a water outlet is connected to one end of the box two.

[0012] Preferably, a circular ring is connected to one end and the other end of the two groups of roller bodies.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Through the coordination between the set box one, pump body and nozzle, when cooling the cast steel parts, the cast steel parts first pass through box one. The fan is started, and the outside air is sprayed onto the surface of the cast steel parts through pipe group one and shell to slowly cool the cast steel parts. After cooling for a period of time, the cast steel parts are transported to box two. The pump body is started, and the water in the water tank is drawn out and sprayed onto the surface of the cast steel parts through pipe group two and nozzle to quickly cool the cast steel parts. While ensuring cooling efficiency, the initial cooling by the fan also avoids deformation or even cracking caused by excessive internal and external temperature difference during water cooling of the cast steel parts, thus improving the quality of the finished product to a certain extent.

[0015] 2. Through the cooperation between the fan, housing, and orifices, the housing is conical. When the fan delivers air to the housing through the pipe assembly, the conical design of the housing, due to the gradually increasing cross-sectional area of ​​the channel, slows down the wind speed to a certain extent. When the air is ejected from the multiple sets of orifices on the housing, it is further divided by the multiple sets of orifices, further reducing the wind speed. To a certain extent, this avoids the casting steel parts being blown away when air-cooling the casting steel parts. For example, some irregularly shaped casting steel parts are difficult to keep stable when placed on the conveyor belt. Being blown away by the wind may cause them to collide with other casting steel parts, resulting in dents on the surface of the casting steel parts. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figures 1 to 5 An automatic annealing device for cast steel parts includes a frame 1 with two sets of rollers 2 rotatably connected to it. A conveyor belt is mounted on the rollers 2, and the rotation of the rollers 2 drives the conveyor belt to move. The conveyor belt can be used to transport cast steel parts. A motor 3 is installed at one end of the frame 1. The model of the motor 3 can be selected according to the actual situation. The motor 3 is connected to one set of rollers 2. Starting the motor 3 drives the rollers 2 to rotate. A heating component 4, a first box 5, and a second box 6 are connected to the frame 1. The heating component 4 is existing technology and will not be described in detail here. The first box 5, the second box 6, and the heating component 4 are connected. A fan 7 is installed on the first box 5. The model of the fan 7 can be selected according to the actual situation. One end of the fan 7 is connected to a pipe assembly 8, which passes through the first box 5. Starting the fan 7 draws outside air through the pipe assembly 8, the housing 9, and the hole. The body 10 sprays water onto the surface of the cast steel part to slowly cool it down. A water tank 11 is connected to the frame 1, and a pump body 12 is installed at one end of the water tank 11. The model of the pump body 12 can be selected according to the actual situation. One end of the pump body 12 is connected to the water tank 11. The pump body 12 is started to draw water out of the water tank 11. One end of the pump body 12 is connected to the pipe assembly 13. The pump body 12 sprays water onto the surface of the cast steel part through the pipe assembly 13 and the nozzle 14 to quickly cool the cast steel part. The pipe assembly 13 passes through the box 6. One end of the pipe assembly 13 is connected to multiple sets of nozzles 14. The cast steel part is first slowly cooled by air cooling, and then the cast steel part is quickly cooled by water cooling. While ensuring the cooling efficiency, it can also avoid the problem of excessive temperature difference between the inside and outside of the cast steel part during water cooling, which may lead to deformation or cracking of the cast steel part.

[0024] In this embodiment, both ends of pipe assembly 8 are connected to housings 9. Multiple sets of orifices 10 are opened at one end of each housing 9. The housings 9 are conical. When pipe assembly 8 delivers air into the housings 9, the channels within the housings 9 gradually widen, which to some extent slows down the wind speed. When the air is ejected through the orifices 10, it is further reduced in speed by being divided by multiple sets of orifices 10, thus preventing the cast steel parts from being blown and damaged by collision. A water tank 11 is connected to an outlet valve 15 at one end, through which liquid is discharged from the water tank 11. A water tank 11 is also connected to an inlet valve 16 at one end, through which water is injected into the water tank 11. A box body 5 is connected to multiple sets of inlets 17 at one end, through which air delivered by the blower 7 is discharged. A box body 6 is connected to an outlet 18 at one end, through which water accumulated inside the box body 6 can be discharged. Both sets of rollers 2 are connected to a ring 19 at one end and the other end. The ring 19 limits the conveyor belt to a certain extent to prevent the conveyor belt from shaking when it is being conveyed.

[0025] The working principle of this embodiment is as follows: In use, the conveyor belt is installed on the roller 2, and the motor 3 is started to drive the roller 2 to rotate. The rotation of the roller 2 drives the conveyor belt to move, and the cast steel part is placed on the conveyor belt. The cast steel part moves to the heating component 4, and the heating component 4 is started to heat the cast steel part. After heating, the cast steel part is carried by the conveyor belt to the housing 5. The fan 7 is started to transport outside air through the pipe group 8 to the housing 9. Because the housing 9 is conical, the cross-sectional area of ​​the channel of the housing 9 gradually increases, which slows down the wind speed. When the air is finally ejected through the multiple sets of holes 10, it is further divided by the multiple sets of holes 10. To further reduce the wind speed, the problem of the cast steel parts being pushed and damaged by collisions with other objects during air cooling is avoided to some extent. The cast steel parts are carried by the conveyor belt and continue to move into the housing 6. The pump 12 is started to draw water from the water tank 11 and spray it onto the surface of the cast steel parts through the pipe assembly 13 and the nozzle 14 to cool the cast steel parts quickly. The cast steel parts are first cooled slowly by air cooling and then cooled quickly by water cooling. While ensuring the cooling efficiency, it can also avoid the problem of excessive temperature difference between the inside and outside of the cast steel parts during water cooling, which could lead to deformation or cracking of the cast steel parts.
