Description

TECHNICAL FIELD

[0001] The application relates to the technical field of steel ball processing equipment, in particular to a steel ball cooling device. BACKGROUND

[0002] In a mining enterprise, a steel ball is usually used in a ball mill as a grinding medium, and the core function thereof is to grind ore materials into finer powder. The steel ball can be obtained by sequentially subjecting a steel bar to heating, cutting, stamping and forging and cooling, wherein the cooling step directly affects the finished product quality of the steel ball.

[0003] The cooling of the steel ball is divided into two stages of precooling and quenching, and the temperature of the steel ball just after forging is usually above 900 DEG C. After a period of natural air cooling, the temperature of the steel ball is reduced (usually to 750-800 DEG C), and then quenching is performed, otherwise, the surface of the steel ball is rapidly cooled and shrinks, while the inside is still in a high-temperature expansion state, resulting in uneven internal and external stress, thereby cracks are generated, and the quality of the steel ball is affected.

[0004] The diameter of the steel ball directly affects the precooling time and quenching water cooling time. Generally speaking, the larger the diameter of the steel ball, the longer the precooling time and quenching water cooling time required, and in the traditional process, the precooling time and quenching water cooling time are judged by the experience of workers, and a large error is prone to occur, thereby the quality of the steel ball is unstable.

[0029] Referring to Figures 1-4 A steel ball cooling device comprises:

[0030] A chassis 1 is welded by square steel, and its size can be adjusted according to actual use requirements;

[0031] A lifting assembly 2 is obliquely installed on the chassis 1, and a plurality of groups of the lifting assembly 2 are arranged in parallel, and the specific number can be increased or decreased according to requirements. In this embodiment, three groups are arranged. Specifically, the lifting assembly 2 comprises a chute 21, an auger 22 and a first motor 23. The chute 21 is made of steel plate and has a concave structure. The chute 21 is obliquely welded on the chassis 1, and the lower side thereof is a feeding end 24, and the higher side thereof is a discharging end 25. The auger 22 is rotatably installed in the chute 21. One end of the auger 22 is rotatably connected to the end of the chute 21, and the other end is rotatably connected to a mounting bracket welded on the chassis 1. The end of the auger 22 is connected to the output shaft of the first motor 23 through a shaft coupling. The first motor 23 can drive the auger 22 to rotate, thereby lifting the steel ball 6. The inclination angle of the lifting assembly 2 is usually set to 10-15°.

[0032] A slide 3 is obliquely installed between two adjacent groups of lifting assemblies 2. The inclination angle of the slide 3 is 3-5°. Under this inclination angle, the steel ball 6 can naturally slide, and the sliding speed of the steel ball 6 can be reduced as much as possible, thereby reducing the impact of the steel ball 6 on the lifting assembly 2. The higher side of the slide 3 is connected to the discharging end 25 of the previous group of lifting assemblies 2, and the lower side thereof is connected to the feeding end 24 of the next group of lifting assemblies 2. By moving the steel ball 6 between the lifting assemblies 2, the running path of the steel ball 6 is prolonged, and the steel ball 6 is fully cooled, thereby laying a foundation for subsequent water cooling. Further, the first motor 23 is selected to be a motor with adjustable speed, and the specific model is selected according to actual requirements. Since the length of the slide 3 is constant, the rolling time of the steel ball 6 on the slide 3 is basically consistent. By adjusting the speed of the first motor 23, the speed of the auger 22 can be changed, thereby changing the lifting speed of the steel ball 6 and realizing the change of the pre-cooling time.

[0033] The water cooling mechanism 5 is connected to the discharge end 25 of the last end group lifting assembly 2 through the connecting channel 4, and the steel ball 6 can be water quenched through the water cooling mechanism 5. The water cooling mechanism 5 comprises a water tank 51, a roller 52, a supporting roller 54 and a second motor 56. The water tank 51 is filled with clean water, and four groups of supports 541 are arranged at the bottom of the water tank 51. The supporting rollers 54 are rotatably arranged on the supports 541. The outer wall of the roller 52 is provided with an annular track 53 corresponding to the supporting rollers 54, and the supporting rollers 54 are connected through the annular track 53, so that the roller 52 can rotate conveniently. The side wall of the roller 52 is uniformly provided with through holes, so that the water in the water tank 51 can enter the roller 52 through the through holes, thereby facilitating the water quenching of the steel ball 6. The inner wall of the roller 52 is further provided with a spiral blade 55 along the axial direction. The second motor 56 can drive the roller 52 to rotate, thereby driving the steel ball 6 in the roller 52 to move along the axial direction and be finally discharged. Specifically, the second motor 56 is an adjustable speed motor, and the specific model is selected according to actual needs. The second motor 56 is fixedly installed on the chassis 1, and the output shaft thereof is connected to a rotating shaft 57 through a shaft coupling. The rotating shaft 57 is concentrically arranged with the roller 52, and one end of the rotating shaft 57 is rotatably arranged on a support 58, and the other end extends into the roller 52. A connecting rod 571 is arranged on the rotating shaft 57 along the radial direction, and the end of the connecting rod 571 is welded and fixedly connected to the inner wall of the roller 52. The second motor 56 can drive the roller 52 to rotate. Since the length of the spiral blade 55 in the roller 52 is fixed, the water quenching time of the steel ball 6 can be adjusted by controlling the rotating speed of the roller 52, thereby ensuring the quality of the steel ball.

[0034] Specific working process:

[0035] The worker clamps the heated blank by using the calipers, and uses the air hammer to punch and forge to form the steel ball 6. After forging, the steel ball 6 is placed into the feeding end 24 of the frontmost lifting assembly 2. The steel ball 6 is lifted to the discharge end 25 under the action of the auger 22, and then falls from the discharge end 25 to the slide 3 and rolls to the feeding end 24 of the next lifting assembly 2. The process is repeated to naturally air cool the steel ball 6. The naturally air cooled steel ball 6 slides into the roller 52 from the connecting channel 4, and the steel ball 6 is always located at the bottom of the roller 52 under the action of gravity, so that the steel ball 6 is in full contact with the cooling water in the water tank 51 for water quenching. Since the roller 52 is constantly rotating, the steel ball 6 is forced to roll constantly, which is beneficial to destroy the vapor membrane formed during water quenching of the steel ball 6, thereby ensuring the water quenching quality. With the rotation of the roller 52, the steel ball 6 moves along the axial direction of the roller 52 and is finally discharged. After the steel balls 6 are collected uniformly, tempering treatment is performed.
