Description

Technical Field

[0001] The utility model relates to the field of screws, in particular to a quenching and cooling device for screw production. Background Art

[0002] A screw is a tool that uses the physical and mathematical principles of the circular rotation of an object's inclined surface and friction to fasten objects and machines. The production process of a screw requires multiple steps, and quenching is one of them. Screw quenching refers to the process of heating the screw to a certain temperature and then rapidly cooling it, which can cause a phase change in the structure of the screw, thereby increasing its hardness and wear resistance. It is suitable for screw products that require high strength and high wear resistance, and is needed after quenching. A quenching cooling device refers to a device that cools metal materials and components after they are heated to a certain temperature in a predetermined manner and rate to obtain the expected structure and performance.

[0003] After searching, a quenching and cooling device for high-strength screw production is found with publication number CN215887160U, which specifically discloses a quenching and cooling device for high-strength screw production. Aiming at the problem that when the existing quenching and cooling device for screw production is in use, the coolant temperature near the screws is high due to the lack of flow of the coolant, resulting in poor quenching and cooling effect on the screws, the following scheme is proposed, which includes a cooling box, a water tank is fixedly installed on the outside of one side of the cooling box, a liquid inlet pipe and a liquid outlet pipe are respectively arranged between the two same sides of the water tank and the cooling box, two symmetrically distributed electric doors are arranged on the top of the cooling box, a bearing plate is movably installed in the cooling box, two symmetrically distributed limit rods are fixedly installed on the inner wall of the bottom end of the cooling box, a spring is movably sleeved on the limit rod, and a stirring mechanism is arranged in the cooling box. The utility model can not only improve the fluidity of the coolant in the cooling box, but also reduce the emission of toxic gases.

[0004] During use of the existing quenching and cooling device for screw production, since the temperature of the screws is too high after production, the screws will be quickly cooled if they are directly in rapid contact with the coolant. However, with the exchange of heat and cold, the temperature of the coolant rises rapidly, which is not suitable for quenching and cooling the next batch of screws. The coolant needs to be replaced frequently to ensure the cooling temperature of the screw production quenching. In addition, the continuous cooling of the coolant in the above-mentioned comparative case is costly, which is not conducive to the quenching and cooling of screws in mass production. Moreover, the non-flow of the coolant will also cause a slow cooling process.

[0005] Therefore, it is necessary to invent a quenching cooling device for screw production to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a quenching and cooling device for screw production. Through a cooling cabinet, an impurity filter, a drain pipe, an electromagnetic control valve, a heat exchange cooling pipe, a pressurized water pump and a reflux pipe, not only can the coolant of the device always maintain a cooling temperature, but also avoid the tedious operation of workers frequently changing the coolant, so that the coolant is circulated and used. The impurity filter can also ensure the purity of the coolant, and the cost of continuous cooling of the coolant is reduced. The extraction and re-injection of the coolant also keep the coolant flowing continuously during the cooling process, which is convenient for the device to be used for quenching and cooling of large quantities of screws. The effect is to solve the problem that during the use of the quenching cooling device for screw production in the prior art, since the temperature of the screws is too high after production, if they are directly in rapid contact with the coolant, the screws will be cooled quickly. However, with the exchange of hot and cold, the temperature of the coolant rises rapidly, which is not suitable for quenching and cooling the next batch of screws. The coolant needs to be replaced frequently to ensure the cooling temperature of the screw production quenching. In addition, the continuous cooling method of the coolant in the above-mentioned comparative case is relatively costly, which is not conducive to the quenching and cooling of screws in batch production. Moreover, the non-flow of the coolant will also cause the problem of a slow cooling process.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a quenching cooling device for screw production, comprising a cooling box for carrying a coolant to cool the screw;

[0008] A cooling cabinet is arranged inside the cooling box body, and is used as a component for assisting the screws to complete cooling. An impurity filter is arranged inside the cooling cabinet.

[0014] Preferably, the number of the stirring blades is set to be multiple, and the multiple stirring blades are distributed in a ring array on the stirring rod.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The utility model provides Figure 1-5 The quenching cooling device for screw production shown includes a cooling box 1 for carrying a coolant to cool the screw;

[0029] A cooling cabinet 2 is arranged inside the cooling box body 1 and is used to assist the screws in completing the cooling. An impurity filter 3 is arranged inside the cooling cabinet 2. A fixed card slot 4 is provided above the cooling box body 1. A fixed card block 5 is movably connected inside the fixed card slot 4. An upper closing cover 6 is fixedly installed at one end of the fixed card block 5. A feed port 7 is arranged above the upper closing cover 6.

[0030] The discharge pipe 11 is arranged at the bottom of the cooling cabinet 2, and is used for rapid heat exchange of the coolant. An electromagnetic control valve 12 is fixedly installed at one end of the discharge pipe 11, and a heat exchange cooling pipe 13 is fixedly installed at the other end of the electromagnetic control valve 12;

[0031] A fixing frame 14 is arranged on one side of the outside of the cooling box body 1 and is used for connecting and installing a pressurized water pump 15, and a return pipe 16 is fixedly installed at one end of the pressurized water pump 15. The heated coolant in the cooling cabinet 2 is allowed to flow into the heat exchange cooling pipe 13 through the electromagnetic control valve 12. The coolant in the lower space of the cooling box body 1 and the heated coolant in the heat exchange cooling pipe 13 are heat exchanged to make the liquid in the heat exchange cooling pipe 13 cool again, and then it is extracted through the pressurized water pump 15 and the return pipe 16 and re-injected into the cooling cabinet 2. This not only allows the coolant of the device to always maintain a cooling temperature, but also avoids the tedious operation of workers frequently changing the coolant.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the cooling cabinet 2 is movably connected to the cooling box body 1, and the impurity filter 3 is fixedly connected to the cooling cabinet 2. The impurity filter 3 can also ensure the purity of the coolant and filter out impurities dropped from the screws during the cooling process. The fixed block 5 fixedly installed at the bottom of the upper closing cover 6 is engaged with the fixed slot 4 opened on the top of the cooling box body 1. The fixed block 5 is used in conjunction with the fixed slot 4 to facilitate the installation of the upper closing cover 6 to avoid a large amount of smoke escaping during quenching and cooling, thereby affecting the surrounding environment. A servo motor 8 is arranged above the upper closing cover 6, and a stirring rod 9 is fixedly connected to the output end of the servo motor 8. A stirring blade 10 is fixedly installed on the outside of the stirring rod 9. The stirring blade 10 is driven by the servo motor 8 to fully stir the coolant and the screw, thereby accelerating the cooling speed of the screw.

[0033] like Figure 1 , Figure 4 and Figure 5 As shown, the number of stirring blades 10 is set to be multiple, and the multiple stirring blades 10 are distributed in a ring array on the stirring rod 9. The stirring blades 10 have a simple structure and are easy to operate. If a fault occurs, it is also convenient for maintenance personnel to replace and repair them in time. A mounting frame 17 is fixedly installed on the other side of the outside of the cooling box 1, and a vacuum air pump 18 is arranged above the mounting frame 17. A dust box 19 is arranged on one side of the vacuum air pump 18, and an exhaust pipe 20 is fixedly installed on one end of the vacuum air pump 18. The other end of the exhaust pipe 20 is fixedly connected to a smoke outlet 21. A large amount of smoke will be generated during the quenching, cooling and stirring process. The smoke can be directly drawn into the dust box 19 through the vacuum air pump 18, thereby reducing the impact of the smoke on the surrounding operating environment.

[0034] The practical working principle of the present invention is as follows: firstly, the external power supply is turned on, and an appropriate amount of coolant is poured into the lower space inside the cooling box body 1, and then the cooling cabinet 2 is installed in the cooling box body 1, and then the upper closing cover 6 is closed through the fixing slot 4 and the fixing block 5, and the screws that need to be quenched and cooled are put into the feed port 7 in batches, and then the screws enter the impurity filter 3 of the cooling cabinet 2 along the feed port 7. After the high-temperature screws and the low-temperature coolant are quickly in contact, the switch of the servo motor 8 can be turned on, and the stirring blade 10 driven by the servo motor 8 allows the coolant and the screws to be fully stirred, which can speed up the cooling speed of the screws. Subsequently, a large amount of smoke will be generated during the quenching, cooling and stirring process, which can turn on the switch of the vacuum air pump 18, and the smoke will be directly drawn into the dust box 19 through the vacuum air pump 18, thereby reducing the impact of the smoke on the surrounding operating environment. After the current batch of screws has been cooled, they can be directly fished out, and then the electromagnetic control valve 12 is used to allow the heated coolant in the cooling cabinet 2 to flow into the heat exchange cooling pipe 13, and then The coolant in the lower space of the supercooling box 1 and the heated coolant in the heat exchange cooling pipe 13 are heat exchanged to make the liquid in the heat exchange cooling pipe 13 cool again, and then the switch of the pressurized water pump 15 is turned on again, and the coolant after cooling is extracted through the pressurized water pump 15 and the reflux pipe 16 and re-injected into the cooling cabinet 2. This not only allows the coolant of the device to maintain the cooling temperature all the time, but also avoids the tedious operation of workers frequently changing the coolant, so that the coolant is recycled, and the impurity filter 3 can also ensure the purity of the coolant. The extraction and re-injection of the coolant also allows the coolant to maintain continuous flow during the cooling process, and then the next batch of screws can be put into quenching and cooling. Finally, after completing the installation and use of all the quenching and cooling devices for screw production according to the above operations, turn off the switch of the servo motor 8, turn off the switch of the pressurized water pump 15, turn off the switch of the vacuum air pump 18, and cut off the external power supply if it is not used for a long time. In this way, the use process of the quenching and cooling device for screw production is completed.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
