Description

Technical Field

[0001] The utility model relates to the technical field of tempering devices, in particular to a tempering device for steel ball production. Background Art

[0002] Tempering is a step in the heat treatment process, the main purpose of which is to improve the mechanical properties of steel balls. Although quenching a steel ball can greatly increase its hardness and strength, it also causes the steel ball material to become brittle, reduces its toughness, and makes the steel ball prone to breakage. To address this problem, tempering is usually performed after quenching. By heating the quenched steel ball to a specific temperature below the critical temperature, holding it for a period of time, and then cooling it, tempering can reduce the internal stress of the steel ball material, improve its toughness and ductility, and maintain a certain hardness. This process helps stabilize the steel ball structure, reduce dimensional changes, and improve the processing performance of the steel ball.

[0003] Generally, when tempering steel balls, multiple steel balls are piled up in a collection frame and then heated. This stacking method easily causes uneven contact between the steel balls, resulting in low heat conduction efficiency, causing the steel balls inside the collection frame to be heated unevenly. The steel balls close to the heating source may overheat, while the parts far away from the heating source may not reach the ideal temperature. This not only affects the consistency of material properties, but may also cause some steel balls to deform or be damaged due to local overheating. In addition, due to the uneven heat distribution, the efficiency of the entire heating process will also be reduced, increasing energy consumption and production costs. Utility Model Content

The side of the tempering box 3 away from the heating fan 2 is hingedly connected to the hinged door 4. The bottom of the tempering box 3 is fixedly connected to the high-temperature cylinder 5. The exhaust end of the heating fan 2 is connected to the high-temperature cylinder 5. , the top of the high-temperature cylinder 5 is fixedly connected with an air supply pipe 6, the air supply pipe 6 is divided into five side air supply pipes 6 and a top air supply pipe 6, the five side air supply pipes 6 are connected to the top air supply pipe 6, the top air supply pipe 6 is located at the top of the tempering box 3, a motor 8 is installed on the top of the tempering box 3, the middle of the tempering box 3 is rotatably connected with a rotating rod 9, the top of the rotating rod 9 passes through the top of the tempering box 3, the bottom of the rotating rod 9 is rotatably connected to the high-temperature cylinder 5, the output shaft of the motor 8 is transmission-connected to the rotating rod 9, and the side of the air supply pipe 6 close to the rotating rod 9 is There is an air outlet 7, four support plates 11 are fixedly connected to the rotating rod 9, and five groups of placement slots 14 are opened on the top of the support plate 11. The five groups of placement slots 14 are evenly distributed along the circumference of the support plate 11. Each group of placement slots 14 can place two steel balls. The top of the tempering box 3 is fixedly connected with a sealing cover 10 for shielding the connection between the rotating rod 9 and the tempering box 3, which can prevent hot air from leaking from the connection between the rotating rod 9 and the tempering box 3. Five inclined slots 110 are opened on the top of the support plate 11 along the circumference, and each group of placement slots 14 is located at the corresponding inclined slots. In the groove 110, the side of the inclined groove 110 close to the rotating rod 9 is higher than the side away from the rotating rod 9. Four discharge frames 12 are fixedly connected to the inside of the tempering box 3. Each discharge frame 12 is located at the bottom of each support plate 11. The side of the discharge frame 12 away from the heating blower 2 is fixedly connected to a discharge hopper 13. The discharge frame 12 and the discharge hopper 13 are both inclined to ensure that the steel balls can flow along the discharge frame 12 to the discharge hopper 13, and finally fall out of the tempering box 3 from the discharge hopper 13. A pushing assembly is connected to the bottom of the support plate 11.

[0020] like Figure 3-Figure 5As shown, the pusher assembly includes a wedge block 17, an outer ring 18 and an inner ring 19. The outer ring 18 is rotatably connected to the inner wall of the tempering box 3, and the inner ring 19 is fixedly connected to the inner wall of the outer ring 18. The tops of the outer ring 18 and the inner ring 19 are both fixedly connected to the wedge block 17. The bottom of the support plate 11 is provided with a through groove 15 for the wedge block 17 on the top of the inner ring 19 to move and an arc groove 16 for the wedge block 17 on the top of the outer ring 18 to move.

[0021] Initially, the wedge block 17 is away from the placement groove 14. When the steel ball needs to be tempered, the hinged door 4 is opened, and the steel ball is placed in the placement groove 14. The bottom of the steel ball above the outer ring 18 contacts the outer ring 18, and the bottom of the steel ball above the inner ring 19 contacts the inner ring 19. The hinged door 4 is closed, and the hot air is discharged into the high-temperature tube 5 through the heating blower 2. The hot air in the high-temperature tube 5 is discharged into the tempering box 3 through the air outlet 7 of the air supply pipe 6. The top air supply pipe 6 can blow the hot air to the steel ball on the top support plate 11, and the side air supply pipe 6 can blow the hot air To the steel balls of other support plates 11, under the cooperation of the air supply pipes 6 at different positions, the hot air can quickly fill the tempering box 3 and heat the steel balls evenly.

The side of the arc groove 16 close to the side plane of the wedge block 17 is close to the wedge block 1 7. When the wedge block 17 contacts the side of the arc groove 16 close to the side plane of the wedge block 17, under the rotation of the support plate 11, the support plate 11 will drive the outer ring 18 to rotate, thereby causing the inner ring 19 to rotate at the same time, and the wedge block 17 on the inner ring 19 moves along the through groove 15. When the steel ball is heated to the required temperature, the heating fan 2 is turned off, the hinged door 4 is opened, and the motor 8 drives the rotating rod 9 to reverse, and the rotating rod 9 reverses to drive the support plate 11 to reverse. The wedge blocks 17 all move close to the placement groove 14, and the inclined surface of the wedge block 17 squeezes the steel ball. , so that the steel balls all move upward and leave the placement groove 14. After leaving the placement groove 14, the steel balls slide along the inclined groove 110 away from the support plate 11. After the steel balls fall into the discharge frame 12 from the inclined groove 110, they enter the discharge hopper 13 along the discharge frame 12, and then fall out of the tempering box 3 from the discharge hopper 13. The heated steel balls are then collected and cooled by standing, water cooling or oil cooling. In this way, the tempering treatment of the steel balls is completed. When the next batch of steel balls needs to be heated, the motor 8 is used to drive the support plate 11 to reset through the rotating rod 9.
