Description

Technical Field

[0001] This utility model relates to the field of steel ball production technology, and in particular to a steel ball tempering and sorting device. Background Technology

[0002] In the production of steel balls, quenching and tempering processes are typically required to improve their quality. Tempering involves reheating quenched steel balls to a suitable temperature below their lower critical temperature, holding them at that temperature for a period, and then cooling them in air, water, or oil – a metal heat treatment process. Alternatively, quenched wear-resistant steel balls can be heated to a suitable temperature, held for a certain time, and then slowly or rapidly cooled to improve their ductility or toughness. Simultaneously, due to differences in the manufacturing process, steel balls may vary in size and shape, necessitating sorting to ensure product consistency. Existing tempering and sorting equipment has a relatively simple structure and function, making continuous production difficult. Structural improvements are necessary to enhance performance and efficiency. Utility Model Content

The sorting device includes a sieve plate 8, a stirring device, and a discharge plate 9. The sieve plate 8 and the discharge plate 9 are installed vertically within the sieve plate 8. The stirring device is installed within the sieve plate 8 and includes a stirring motor 4, a stirring shaft 5, and stirring blades 6. The stirring motor 4 is fixedly mounted on a mounting plate 3 in the middle of the frame 1. The stirring shaft 5 is connected to the output shaft of the stirring motor 4 and extends upward through the discharge plate 9 and the sieve plate 8. The stirring blades 6 are evenly installed on the stirring shaft 5 above the sieve plate 8. This device is easy to operate, enabling continuous operation of the tempering and sorting devices, significantly improving efficiency, and producing high-quality products.

[0022] Specifically, the support plate 21 is provided with a plurality of ventilation holes evenly distributed to achieve uniform heating and improve processing efficiency.

[0023] Specifically, the bearing plate shaft 19 is fixed with a screw mounting bracket 20, and the screw mounting bracket 20 is provided with a threaded rod 22. The bearing plate 21 is hinged on the bearing plate shaft 19, and the threaded rod 22 is threadedly connected to the bearing plate 21. Rotating the threaded rod 22 can realize the bearing plate 21 to rotate up and down slightly on the bearing plate shaft 19, thereby adjusting the upward or downward tilt state of the outer end of the bearing plate 21.

[0024] Specifically, the top of the threaded rod 22 is provided with a knob, which is movably fitted with the screw knob 23. The top of the tempering barrel 16 is provided with an operating hole and a movable cover plate. After tempering is completed, the cover plate is opened, the screw knob 23 is inserted through the operating hole, the threaded rod 22 is rotated to adjust the outer end of the support plate 21 to a downward tilting state, and then the screw knob 23 is removed and the cover plate is closed. The operation is convenient and the adjustment is accurate.

[0025] Specifically, a hot air assembly 17 is installed inside the tempering barrel 16. The hot air assembly 17 is connected to the hot air circulation pipeline to maintain the temperature during the tempering process. It is easy to adjust and accurately control the temperature.

[0026] Specifically, the pneumatic discharge switch includes a power cylinder 12 and a slide plate 13. The cylinder shaft of the power cylinder 12 is connected to the slide plate 13. The slide plate 13 is horizontally arranged and makes contact with the discharge port of the tempering barrel 16. The power cylinder 12 can push the slide plate 13 to realize the opening or closing of the discharge port.

[0027] Specifically, the power cylinder 12 is detachably mounted on the top plate 2 via the shock-absorbing pad 11, which ensures good reliability and ease of use.

[0028] Specifically, the upper feed inlet of the screen plate 8 is provided with several guide plates 10, which are arranged at an angle and in a staggered manner to reduce the feeding speed and make the conveying more stable.

[0031] In practical implementation, this invention first heats the steel balls on the support plate 21 under suitable temperature conditions. The upper drive motor 18 drives the support plate shaft 19 and the support plate 21 to rotate, making the heating more uniform and the processing efficiency higher. After heating, the balls are cooled. After the process time is reached, stirring is stopped. The screw knob 23 is used to rotate the threaded rod 22, causing the hinged support plate 21 to tilt downward at a small angle. The screw knob 23 is removed, and then the drive motor 18 is started to rotate the support plate 21. Under the action of centrifugal force and gravity, the steel balls fall from the discharge port in the middle of the tempering barrel 16 to the screen plate 8. In the screen plate 8, the stirring motor 4 is started to drive the stirring shaft 5 and stirring blades to rotate. During continuous stirring, steel balls smaller than the screen holes fall from the screen plate 8 to the discharge plate 9 and are sent out from the discharge pipe on the side of the discharge plate 9. Steel balls larger than the screen holes are sent out from the discharge pipe on the side of the screen plate 8, thereby achieving the sorting effect.

[0032] It should be noted that the above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Equivalent modifications made based on the above embodiments are all within the scope of protection of the present utility model.
