Description

Technical Field

[0001] This utility model relates to the field of induction hardening technology, specifically a load hardening component and equipment suitable for the overall hardening of the inner and outer rings of large bearings. Background Technology

[0002] Large bearings play a crucial supporting role in various heavy machinery and equipment. Their main function is to bear radial and axial loads and reduce rotational friction through rolling contact. Because they operate under high load and high speed conditions, the inner and outer rings of the bearings must have high hardness and wear resistance to ensure long service life and high performance.

[0003] To meet the requirements for high hardness and high wear resistance, the inner and outer rings of large bearings are typically hardened. The hardening process alters the microstructure of the material through rapid heating and cooling, thereby significantly improving its hardness and wear resistance.

[0004] Existing induction hardening technologies without soft bands typically employ scanning hardening, where an inductor moves point-by-point across the workpiece surface to heat it. For large workpieces such as the inner and outer rings of large bearings, this point-by-point scanning process is extremely time-consuming, significantly reducing processing efficiency. Furthermore, large workpieces require continuous, uninterrupted hardening, demanding long-term full-load operation of the high-frequency power supply, which can easily lead to equipment overheating and necessitates an additional cooling system, increasing energy consumption and maintenance costs. Traditional methods such as integral bainitic hardening require slow cooling to the isothermal region at the critical cooling rate; however, improper selection of the cooling medium can easily lead to the incorporation of non-target structures such as pearlite or martensite, reducing the workpiece's hardness and wear resistance. This uncertainty affects the stability of the hardening quality, especially for large workpieces, where ensuring cooling uniformity is difficult and can easily result in soft bands or deformation. Utility Model Content

The load-bearing beam mounting beam can make the two load-bearing quenching beam assemblies form an included angle of a certain angle, which can correspond to various workpiece sizes. The heating range of a single load-bearing quenching component is determined according to the workpiece size and the size of the inductor.

[0033] The working principle of this utility model is as follows: Before processing begins, the machine tool injects quenching fluid into the quenching water tank through the water collector and water distributor of the rotary table rotating component.

After multiple load quenching components reach the appropriate position, the components cooperate to form an overall quenching effect. Afterward, the turntable rotating component drives the workpiece clamping component to rotate, and the load sensor component starts heating. After heating to the appropriate temperature and time, the load sensor component stops heating, and the locking mechanism of the turntable lifting component retracts, causing the turntable lifting component to drive the turntable rotating component and the workpiece clamping component to descend into the quenching water tank. The quenching water tank completes the quenching of the workpiece (a water spray cooling system can also be added to the load sensor component to complete the quenching of the workpiece, which can be selected as needed). After quenching is completed, the workpiece driving component drives the workpiece clamping component to move to the appropriate position to remove the workpiece, and the overall quenching is completed.
