Description

Technical Field

[0001] This utility model belongs to the field of quenching heat treatment technology, specifically relating to a quenching fixture that can rotate automatically. Background Technology

[0002] Quenching heat treatment is the process of heating a workpiece in a furnace, removing it from the furnace, and then placing it in a quenching tank for quenching. The quenching medium can be water, oil, or a water-soluble solvent. Currently, due to environmental protection requirements, most well-type quenching oil tanks are equipped with fume hoods or similar devices, which prevents the workpiece from rotating during the quenching process, allowing it to only move around. In contrast, quenching tanks without overhead shielding, such as tempering tanks, require manual rotation of the fixtures during the quenching process, which has the disadvantage of a higher risk factor. Utility Model Content

[0003] The purpose of this invention is to address the defects and shortcomings of existing technologies by designing a simple, stable, and reliable quenching fixture that can automatically rotate, increase quenching uniformity, reduce workpiece deformation, and reduce labor costs.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: an automatically rotating quenching fixture, including a rotating base suspended in a quenching tank, and a medium circulation pumping pipeline corresponding to the rotating base. The rotating base includes a lifting rod hole that rotates with the lifting rod, and several fan blades distributed on the outer periphery of the lifting rod hole. The fan blades are connected to main stiffening plates, and side stiffening plates are provided between adjacent fan blades. An outer ring stiffening plate is also provided on the side of the fan blade away from the lifting rod hole.

[0005] Preferably, the rotating chassis is suspended in the quenching tank by a crane.

[0006] Preferably, the boom hole extends through the rotating chassis, with one end of the boom connected to the boom hole and the other end connected to the crane chuck.

[0007] Preferably, there are two medium circulation pumping pipelines, symmetrically distributed on the left and right sides of the quenching tank.

[0008] Preferably, the outlet of the medium circulation pumping pipeline is located below the rotating chassis.

[0009] Preferably, a fume hood is also provided above the quenching tank.

[0010] By adopting the above technical solution, the automatically rotating quenching fixture provided by this utility model has the following beneficial effects:

[0011] (1) The quenching fixture of this utility model can realize the workpiece to rotate in the quenching tank, which can improve the uniformity of the quenching process, reduce the risk of quenching cracking, and improve the overall quality of the workpiece.

[0012] (2) The quenching fixture of this utility model does not require electricity to rotate, saving electricity costs. The fixture can be flexibly customized according to the size of the quenching tank. Moreover, the technology is mature in the market, the customization cost is low, and it is applicable to various quenching tanks with circulation devices. No additional modification costs are required, and the application range is wide.

[0013] (3) The quenching fixture of this utility model can reduce the risk of manual operation and increase the safety factor of the quenching process. Attached Figure Description
