Description

Technical Field

[0001] This utility model relates to the field of high-precision steel ball processing technology, specifically a cooling device for high-precision steel ball processing. Background Technology

[0002] High-precision steel balls are spherical iron alloy wear-resistant bodies made primarily of carbon, chromium, manganese, molybdenum, and other metallic elements, produced through forging, spinning, rolling, grinding, and casting. They are a crucial component of the crushing and bearing industries today. During the processing of high-precision steel balls, they undergo quenching treatment. After quenching, the high-precision steel balls reach a high temperature and need to be cooled before further processing can proceed.

[0003] For example, the patent application number 202321360041.2 discloses a bearing steel ball cooling device, which solves the problem of steel balls not being cooled and detaching from the screen frame. However, it has problems such as inconvenience in fully maneuvering high-precision steel balls, insufficient cooling of high-precision steel balls, low cooling efficiency, and poor cooling effect.

[0004] Based on this, the applicant proposes a cooling device for high-precision steel ball machining. Utility Model Content

[0005] The purpose of this invention is to address the problems of existing high-precision steel ball cooling devices, such as inconvenience in fully maneuvering the high-precision steel ball, insufficient cooling, low cooling efficiency, and poor cooling effect. The invention provides a high-precision steel ball processing cooling device with a reasonable structural design, capable of circulating the high-precision steel ball, fully cooling the high-precision steel ball, high working efficiency, and good cooling effect.

[0006] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0007] A cooling device for high-precision steel ball processing includes a cooling box, an adjusting plate, and a rotating shaft. The cooling box is mounted on a support. A lifting cylinder is located at the bottom of the cooling box, and a column is located at the top of the cooling box. A top plate is located at the top of the column, and a pushing structure is located on the top plate. High-precision steel balls in the cooling box enter the lifting cylinder. After being lifted in the lifting cylinder, the high-precision steel balls flow back into the cooling box, allowing the high-precision steel balls to circulate between the cooling box and the lifting cylinder, thus providing sufficient cooling treatment and improving the cooling efficiency and effect. The adjusting plate is connected to the pushing structure and has a fixing ring and a driving structure. The adjusting plate moves vertically under the action of the pushing structure, which can drive the rotating shaft and the driving structure to rise or fall, facilitating the lifting plate to lift high-precision steel balls of different heights in the lifting cylinder. The rotating shaft passes vertically through the fixing ring, allowing the rotating shaft to... The shaft is movably connected to the drive structure. A fixed plate is installed on the rotating shaft below the adjustment plate. The bottom end of the rotating shaft extends into the lifting cylinder, and a spiral lifting plate is installed on the rotating shaft inside the lifting cylinder. The motor drives the rotating shaft to rotate, and the rotating shaft drives the lifting plate to rotate. The lifting plate lifts the high-precision steel balls in the lifting cylinder and then returns them to the cooling box, so that the high-precision steel balls circulate between the cooling box and the lifting cylinder, which fully cools the high-precision steel balls, thereby improving the cooling efficiency and cooling effect. The fixed plate is equipped with an exhaust pipe and a toggle rod, and an exhaust fan is installed in the exhaust pipe. The fixed plate rotates under the action of the rotating shaft, and the toggle rod can agitate the high-precision steel balls between the cooling box and the lifting cylinder. The exhaust fan carries the heat of the steel balls out of the exhaust pipe through the airflow between the steel balls, which cools the high-precision steel balls and improves the cooling efficiency and cooling effect.

[0008] Preferably, the bottom of the cooling box is designed with an arc shape, and a discharge hopper is provided at the bottom of the cooling box. A valve is provided on the discharge hopper. By designing the bottom of the cooling box with an arc shape and opening the valve on the discharge hopper, the cooled high-precision steel balls can be quickly rolled into the discharge hopper, allowing for rapid unloading of the high-precision steel balls. This avoids the high-precision steel balls remaining at the bottom of the cooling box after cooling, and can improve the unloading efficiency of the high-precision steel balls.

[0009] Preferably, the bottom end of the lifting cylinder is provided with a feed inlet. During the cooling process, the high-precision steel balls in the cooling box enter the lifting cylinder through the feed inlet. The lifting plate on the rotating shaft inside the lifting cylinder lifts the high-precision steel balls in the lifting cylinder and then returns them to the cooling box, so that the high-precision steel balls circulate between the cooling box and the lifting cylinder, and are fully cooled, thereby improving the cooling efficiency and cooling effect of the high-precision steel balls.

[0010] Preferably, the pushing structure includes a hydraulic cylinder, which is mounted on the top plate. A piston rod is mounted on the hydraulic cylinder, and a connecting rod is mounted on the piston rod. The adjusting plate is connected to the connecting rod. A limit ring is mounted on the adjusting plate, and the column passes vertically through the limit ring. The adjusting plate moves vertically under the action of the pushing structure, which can drive the rotating shaft and drive the structure to rise or fall. This facilitates the lifting plate to lift high-precision steel balls of different heights in the lifting cylinder, and also facilitates the actuating rod on the fixed plate to actuate the high-precision steel balls of different heights, thereby improving the cooling efficiency and cooling effect of the high-precision steel balls.

[0011] Preferably, the drive structure includes a motor mounted on an adjustment plate, a drive shaft mounted on the motor, a drive wheel mounted on the drive shaft, and a driven wheel mounted on the rotating shaft. The driven wheel is connected to the drive wheel via a transmission belt. The motor drives the rotating shaft to rotate, which in turn drives the lifting plate and the fixed plate to rotate. The lifting plate lifts the high-precision steel balls in the lifting cylinder and then returns them to the cooling box, allowing the high-precision steel balls to circulate between the cooling box and the lifting cylinder. The fixed plate drives the actuating rod to rotate, which fully agitates and cools the high-precision steel balls, thereby improving the cooling efficiency and effect of the high-precision steel balls.

[0012] Preferably, the fixing plate has an inner cavity that is connected to the exhaust pipe. The actuating rod is a hollow structure and is connected to the inner cavity. The exhaust fan carries the heat of the steel balls from the airflow between the steel balls through the exhaust pipe, thereby cooling the high-precision steel balls and improving the cooling efficiency and effect.

[0013] Preferably, the side wall of the actuating lever is provided with an air inlet groove. Through the air inlet groove on the actuating lever, the airflow can carry the heat of high-precision steel balls of different heights into the hollow actuating lever, into the inner cavity of the fixed plate, and out through the exhaust pipe, thereby realizing the cooling treatment of high-precision steel balls of different heights, thereby improving the cooling efficiency and cooling effect of high-precision steel balls.

[0014] Beneficial effects:

[0015] 1. The high-precision steel balls in the cooling box enter the lifting cylinder through the feed port. The lifting plate on the rotating shaft in the lifting cylinder lifts the high-precision steel balls in the lifting cylinder and then returns them to the cooling box. This allows the high-precision steel balls to circulate between the cooling box and the lifting cylinder, thus fully cooling the high-precision steel balls and improving the cooling efficiency and cooling effect.

[0016] 2. The motor drives the rotating shaft to rotate, which in turn drives the lifting plate and the fixed plate to rotate. The lifting plate lifts the high-precision steel balls in the lifting cylinder and then returns them to the cooling box, so that the high-precision steel balls circulate between the cooling box and the lifting cylinder. The fixed plate drives the actuating rod to rotate, so that the actuating rod can fully agitate the high-precision steel balls and fully cool them, thereby improving the cooling efficiency and cooling effect of the high-precision steel balls.

[0017] 3. An inner cavity is provided inside the fixed plate, which is connected to the exhaust pipe. The actuating rod is a hollow structure and is connected to the inner cavity. The exhaust fan carries the heat of the steel balls from the airflow between the steel balls through the exhaust pipe to cool the high-precision steel balls, thereby improving the cooling efficiency and cooling effect of the high-precision steel balls.

[0024] The present invention will now be described in more detail with reference to the accompanying drawings.

[0025] Example 1:

[0026] As attached Figures 1-3As shown, a cooling device for high-precision steel ball processing includes a cooling box 1, an adjusting plate 11, and a rotating shaft 2. The cooling box 1 is mounted on a support 3. A lifting cylinder 5 is installed at the bottom of the cooling box 1. A column 4 is installed at the top of the cooling box 1. A top plate 9 is installed at the top of the column 4, and a pushing structure is installed on the top plate 9. The adjusting plate 11 is connected to the pushing structure. A fixing ring 14 and a driving structure are installed on the adjusting plate 11. The rotating shaft 2 is vertically inserted into the fixing ring 14, movably connecting the rotating shaft 2 to the driving structure. A fixing plate 20 is installed on the rotating shaft 2 below the adjusting plate 11, extending the bottom end of the rotating shaft 2 into the lifting cylinder 5. A spiral lifting plate 21 is installed on the rotating shaft 2 inside the lifting cylinder 5. An exhaust pipe 25 and a toggle rod 24 are installed on the fixing plate 20, and an exhaust fan 27 is installed inside the exhaust pipe 25.

[0027] The bottom of the cooling box 1 is designed with an arc shape. A discharge hopper 6 is provided at the bottom of the cooling box 1, and a valve 8 is provided on the discharge hopper 6. A material inlet 7 is provided at the bottom of the lifting cylinder 5.

[0028] The pushing structure includes a hydraulic cylinder 10, which is mounted on the top plate 9. A piston rod 12 is mounted on the hydraulic cylinder 10, and a connecting rod 13 is mounted on the piston rod 12. An adjusting plate 11 is connected to the connecting rod 13. A limit ring 15 is mounted on the adjusting plate 11, and the column 4 passes vertically through the limit ring 15.

[0029] The drive structure includes a motor 16, which is mounted on an adjustment plate 11. A transmission shaft 17 is mounted on the motor 16, and a drive wheel 18 is mounted on the transmission shaft 17. A driven wheel 19 is mounted on the rotating shaft 2, and the driven wheel 19 is connected to the drive wheel 18 via a transmission belt 22.

[0030] The fixed plate 20 has an inner cavity 23, which is connected to the exhaust pipe 25. The toggle rod 24 is a hollow structure, which is connected to the inner cavity 23. An air inlet groove 26 is provided on the side wall of the toggle rod 24.

[0031] Example 2:

[0032] The following improvements are made based on Example 1, as shown in the appendix. Figures 4-5As shown: A cooling device for high-precision steel ball processing, the rotating shaft 2 is configured as a hollow structure, with an exhaust hole 30 on the rotating shaft 2, a blower 28 on the top plate 9, and an air supply pipe 29 on the blower 28. The air supply pipe 29 extends from the top of the rotating shaft 2 into the hollow rotating shaft 2. The rotating shaft 2 drives the lifting plate 21 to rotate in the lifting cylinder 5, causing the lifting plate 21 to push the high-precision steel ball upward. The high-precision steel ball can circulate between the cooling box 1 and the lifting cylinder 5. The blower 28 blows air into the hollow rotating shaft 2 through the air supply pipe 29, and the air in the rotating shaft 2 is discharged through the exhaust hole 30, which blows and cools the high-precision steel ball in the lifting cylinder 5, improving the cooling efficiency and cooling effect of the high-precision steel ball.

[0033] Working principle: After closing valve 8 on discharge hopper 6, the high-precision steel balls requiring cooling are poured into cooling tank 1. The high-precision steel balls in cooling tank 1 enter lifting cylinder 5 through inlet 7. Blower 28 and motor 16 are started. Motor 16 drives rotating shaft 2 to rotate, which in turn drives lifting plate 21 and fixed plate 20 to rotate. Lifting plate 21 lifts the high-precision steel balls in lifting cylinder 5 and returns them to cooling tank 1, causing the high-precision steel balls to circulate between cooling tank 1 and lifting cylinder 5. Fixed plate 20 drives actuating rod 24 to rotate, causing the actuating rod 24 to fully agitate and cool the high-precision steel balls. Exhaust fan 27 then cools the steel balls. The airflow between the steel balls carries the heat of the steel balls and is discharged through the exhaust pipe 25 to cool the high-precision steel balls. The hydraulic cylinder 10 is activated, and the adjusting plate 11 moves vertically under the action of the hydraulic cylinder 10, which can drive the rotating shaft 2 and the drive structure to rise or fall. This facilitates the lifting plate 21 to lift the high-precision steel balls of different heights in the lifting cylinder 5, and also facilitates the toggle lever 24 on the fixed plate 20 to move the high-precision steel balls of different heights. After the high-precision steel balls have cooled, the valve 8 on the discharge bin 6 is opened. The cooling box 1 with the arc-shaped structure at the bottom can roll the cooled high-precision steel balls into the discharge bin 6 and quickly discharge them from the discharge bin 6, thus completing the cooling process of the high-precision steel balls.
