Description

Technical Field

[0001] The utility model relates to a quenching device, in particular to a quenching device for a height difference sliding column seat of an engineering vehicle suspension, and belongs to the technical field of mechanical manufacturing equipment. Background Art

[0002] With the rapid development of the engineering vehicle industry, the performance requirements for vehicle parts are increasing. As a key component in the engineering vehicle suspension system, the height difference sliding column seat is directly related to the stability and safety of the vehicle in terms of strength and wear resistance. Quenching, as one of the important processes for metal heat treatment, can significantly improve the hardness and wear resistance of the material, thereby meeting the use requirements of the height difference sliding column seat of the engineering vehicle suspension;

[0003] Among them, the "quenching device for mechanical castings" disclosed in the application number "202121154171.1" is also an increasingly mature technology. The filter screen is rotated by a motor so that the end of the filter screen away from the hinged end rotates upward, thereby tilting the filter screen. Through the setting of the first driven gear, the second driven gear and the convex teeth, the filter screen rotates and drives the partition to slide in the vertical direction; the partition slides downward until it completely slides into the inner wall of the quenching box. At this time, the debris outlet is fully opened, and the debris on the filter screen slides down due to its own gravity and enters the debris bin through the debris outlet, which is convenient for centralized cleaning; after cleaning, it only needs to rotate the filter screen in the opposite direction, and the partition is embedded in the groove, thereby closing the debris outlet, which does not affect the normal quenching work, so that the debris cleaning operation does not need to be performed manually, which greatly improves the convenience and practicality of the entire quenching device;

[0004] However, the above method still has the following defects in actual use: in the process of placing parts into the quenching box, high-temperature water vapor is often generated, which can easily cause burns to operators and bring safety hazards to operators. At the same time, residual debris in the water can easily enter between the first driven gear and the filter, causing mechanical damage and affecting the normal use of the filter.
