Description

Technical Field

[0001] This utility model belongs to the technical field of quenching equipment, and in particular relates to a quenching device for wheel forgings. Background Technology

[0002] As an important mechanical component, wheel forgings are widely used in various vehicles and heavy machinery. Their strength, hardness, and wear resistance have a direct impact on their performance. In the production process of wheel forgings, quenching is a key process. Quenching can form a hardened layer on the surface of the forging through rapid cooling, thereby improving its wear resistance and fatigue resistance.

[0003] In traditional wheel forging quenching methods, a stationary quenching process is typically employed. Specifically, the wheel forging is placed in a quenching tank, and the liquid cooling medium cools it by maintaining static contact with the wheel surface. However, this stationary quenching method has certain problems. Because the wheel forging remains in a fixed state during the quenching process, the liquid cooling medium cannot uniformly contact all surfaces of the forging. Insufficient fluidity of the quenching liquid leads to inconsistent cooling rates in different parts of the forging, which may cause temperature differences. This can result in localized overcooling or overheating, affecting the hardening effect of the wheel forging.

[0004] To address these issues, we provide a wheel forging quenching device. Utility Model Content

[0005] The purpose of this invention is to provide a quenching device for wheel forgings. By cooperating with the drive assembly and the lifting assembly, it solves the problem in the prior art that the liquid cooling medium cannot uniformly contact all surfaces of the forging when the forging is kept in a fixed state during the quenching process, and the quenching liquid has insufficient fluidity, resulting in inconsistent cooling rates in different parts of the forging.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a quenching device for wheel forgings, comprising a quenching box containing a quenching medium, a lifting box on top of the quenching box, and a drive assembly inside the lifting box. The drive assembly includes a drive gear inside the lifting box, a gear ring meshing with the surface of the drive gear, an extension rod at the bottom of the gear ring, a horizontal plate fixedly connected to the bottom of the extension rod, and an anti-detachment block fixedly connected to the top of the horizontal plate. The drive assembly drives the wheel forging to rotate. A lifting assembly is located at the bottom of the lifting box, comprising an extension rod sleeved on the horizontal plate, a lifting plate fixedly connected to one side of the extension rod, and a support plate fixedly connected inside the quenching box. The lifting assembly can lift the wheel forging.

[0008] The present invention is further configured such that lifting rings are fixedly connected to the four corners of the top of the lifting box, and a rotating through groove adapted to the extension rod is provided at the bottom of the lifting box.

[0009] The present invention is further configured such that a drive motor is fixedly connected to the top of the hoisting box, and the output end of the drive motor is fixedly connected to a drive gear.

[0010] The present invention is further configured such that a support wheel is movably connected to the bottom of the gear ring via a bearing, and the four extension rods are fixedly connected by an arc-shaped plate.

[0011] The present invention is further configured such that a push box is fixedly connected inside the gear ring, a hydraulic cylinder is fixedly connected inside the push box, the output end of the hydraulic cylinder is fixedly connected to the top of the extension rod, a rotating rod is fixedly connected to the top of the push box, the rotating rod is a hollow tube, and the top of the rotating rod is movably connected to the hoisting box through a bearing.

[0012] The present invention is further configured such that the extension rod has a support groove adapted to the cross plate and the anti-detachment block, and a pad is fixedly connected to the top of the support plate.

[0013] The present invention is further configured such that a triangular plate is fixedly connected to the bottom of the support plate, and one side of the triangular plate is fixedly connected to the inside of the quenching box.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model drives the wheel forging to rotate slowly in the quenching medium through a drive component, so that the quenching liquid can evenly contact all surfaces of the forging, avoiding the problem of uneven cooling in the traditional fixed quenching method. This rotary quenching method effectively reduces local overcooling or overheating, ensures the overall hardening effect of the wheel forging, and improves its wear resistance and fatigue resistance.
