Description

Technical Field

[0001] This utility model relates to the field of high-frequency quenching machine technology, and in particular to a high-efficiency high-frequency quenching machine. Background Technology

[0002] High-frequency quenching technology is a key process for improving the surface hardness and wear resistance of shaft-shaped workpieces (such as motor shafts, gear shafts, etc.). It uses high-frequency induction heating to quickly raise the surface of the workpiece to the austenitizing temperature and then rapidly cools it to form a high-strength martensitic structure. It is widely used in machinery manufacturing, automotive industry, machine tool equipment and other fields.

[0003] However, existing high-frequency quenching machines still have certain drawbacks. For example, most existing devices use heating methods that involve fixing the workpiece in a fixed position or manually pushing it, making it difficult to achieve uniform heating of the entire shaft-shaped workpiece. When heating in a fixed position, the high-frequency induction magnetic field is concentrated in the middle of the coil. The two ends of the shaft-shaped workpiece are not heated enough because they are far from the center of the magnetic field, while the middle area is prone to overheating due to continuous magnetization. This results in a hardness difference along the entire length of the workpiece, with the ends being soft and the middle being brittle, requiring subsequent rework and increasing production costs. Secondly, after the workpiece is heated, it needs to be manually released from the clamp and transported to the cooling water tank. This process is very time-consuming, affecting work efficiency. Furthermore, manual transfer requires operators to be in close contact with the high-temperature workpiece, posing a risk of burns. Utility Model Content

In addition, while clamping the shaft-shaped workpiece, it can also make the workpiece automatically and quickly fall into the water after heating, thereby improving work efficiency and avoiding the risk of burns during the transfer process.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-4 This utility model discloses a high-efficiency high-frequency quenching machine, comprising: a base 1, a high-frequency quenching machine body 2 fixedly connected to the upper surface of the base 1 (the high-frequency quenching machine is a mature existing technology component, and its working principle has been disclosed, so it will not be described in detail here), a quenching coil 3 fixedly connected to the right surface of the high-frequency quenching machine body 2, a quenching box 4 fixedly connected to the right surface of the base 1, a drawer 5 slidably connected to the inner surface of the quenching box 4, a fixing plate 6 fixedly connected to the upper surface of the quenching box 4, a motor 7 fixedly connected to the rear end of the fixing plate 6, and a threaded rod 8 fixedly connected to the output end of the motor 7. A slider 9 is threaded onto the outer surface of the fixed plate 8. A fixed post 10 is fixedly connected to the left surface of the fixed plate 6. A fixed box 11 is fixedly connected to the left surface of the slider 9. A pressure rod 12 is slidably connected to the inner surface of the fixed box 11. A wedge block 13 is fixedly connected to the lower end of the pressure rod 12. A pressure plate 14 is fixedly connected to the upper end of the pressure rod 12. A first inclined block 15 is fixedly connected to the upper surface of the pressure plate 14. A slide rod 16 is fixedly connected to the inner surface of the fixed box 11. A spring 17 is provided on the outer surface of the slide rod 16. A clamping sleeve 18 is slidably connected to the outer surface of the slide rod 16. A fixed connection is made to the upper surface of the clamping sleeve 18. The device includes a second inclined block 19, an opening groove 20 on the outer surface of the clamping sleeve 18, a shaft-shaped workpiece 21 on the inner surface of the opening groove 20, water inside the drawer 5 for quenching after workpiece heating, a handle 22 fixedly connected to the front surface of the drawer 5 for easy removal, a threaded rod 8 rotatably connected to a fixed plate 6, a slider 9 slidably connected to a fixed plate 6 for limiting the movement of the slider 9, a fixed post 10 in contact with the first inclined block 15 for automatic detachment of the shaft-shaped workpiece 21, and a wedge block 13 with the second inclined block 19. Block 19 is slidably connected, and there are two clamping sleeves 18 symmetrically distributed. The outer surface of wedge block 13 is slidably connected to fixed box 11. The outer surface of second inclined block 19 is slidably connected to fixed box 11. The outer surface of clamping sleeve 18 is slidably connected to fixed box 11. One end of spring 17 is fixedly connected to fixed box 11, and the other end of spring 17 is fixedly connected to clamping sleeve 18. The height of first inclined block 15 is equal to the depth of opening groove 20, so that the shaft-shaped workpiece can automatically fall into the water inside the drawer 5 after each section of heating is completed. The high-frequency quenching machine body 2 is electrically connected to an external power supply.

[0027] Working principle: During operation, pressing the pressure plate 14 drives the pressure rod 12 to slide the wedge block 13 along the inclined surface of the second inclined block 19. This causes the clamping sleeves 18 on both sides to move away from each other along the slide rod 16, compressing the spring 17. Then, the shaft-shaped workpiece 21 is passed through the quenching coil 3 and its two ends are placed in the corresponding positions of the opening slots 20. Subsequently, the pressure plate 14 is released. Under the action of the spring 17, the clamping sleeves 18 on both sides will move towards each other, thereby inserting the two ends of the shaft-shaped workpiece 21 into the corresponding opening slots 20, thus completing the clamping and fixing of the shaft-shaped workpiece 21. Then, the high-frequency quenching machine body 2 and the motor 7 are started. Under the action of the high-frequency quenching machine body 2, the high-frequency power supply generates a high-frequency alternating current, which is passed into the quenching coil 3 to form an alternating magnetic field. The shaft-shaped workpiece 21 is placed in the coil. The magnetic field induces eddy currents on the surface of the shaft-shaped workpiece 21, thereby rapidly heating the surface to the austenitizing temperature. At the same time, under the action of the motor 7... The threaded rod 8, driven by the slider 9, moves the clamped shaft-shaped workpiece 21 forward along the quenching coil 3, ensuring that each segment of the shaft-shaped workpiece 21 can fully pass through the high-frequency induction magnetic field formed by the quenching coil 3. This avoids the problem of insufficient heating at both ends and overheating in the middle during traditional fixed-position quenching. As the shaft-shaped workpiece 21 moves forward, the fixed column 10 slides along the inclined surface of the first inclined block 15, thereby applying pressure to the pressure plate 14 and gradually causing the clamping sleeve 18 to unfold to both sides. Since the height of the first inclined block 15 is equal to the depth of the opening slot 20, when the fixed column 10 moves to the highest point of the inclined surface of the first inclined block 15, it will contact the restriction effect on the shaft-shaped workpiece 21. At this time, under the gravity of the shaft-shaped workpiece 21, it will automatically fall into the drawer 5 and come into contact with water for quenching treatment. This reduces manual transfer operations on traditional equipment, improves work efficiency, and reduces the risk of burns.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
