Description

Technical Field

[0001] This utility model relates to the field of heat treatment equipment for forgings, specifically a heat treatment equipment for finished sun gear shaft forgings. Background Technology

[0002] Chinese patent document CN220597568U discloses a heat treatment device for forgings, including a quenching tank and vertical plates. Vertical plates are fixedly connected to the top left and right sides of the quenching tank. A horizontal plate is fixedly connected to the top of the two vertical plates. Two cylinders are fixedly connected to the top of the horizontal plate. The telescopic ends of the cylinders penetrate the horizontal plate and extend to the outside of the horizontal plate. A mounting bracket is fixedly connected to the telescopic ends of the two cylinders. This invention, through the coordinated operation of the quenching tank, vertical plates, horizontal plates, cylinders, mounting bracket, quenching components, fixed plate, support shaft, mesh box, drive motor, drive shaft, drum, wire rope, connecting shaft, and baffle, achieves a good quenching effect. It allows the forgings to continuously tumble back and forth during quenching, ensuring uniform contact between the forgings and the quenching liquid, thereby improving the quenching uniformity of the forgings and greatly enhancing the consistency of the quenching quality, effectively avoiding batch quality problems.

[0003] However, in the above scheme, the fixed plate at the bottom of the lifting mounting frame is rotatably connected to one side of the mesh box, and the end of the steel wire rope wound in the drum installed on the lifting mounting frame is fixedly connected to the other side of the mesh box. The motor drives the drum to rotate and unwind the steel wire rope, thereby making the mesh box swing in the quenching pool. This allows the sun gear shaft forging to continuously tumble back and forth during quenching, improving the uniformity of quenching. During use, residual quenching slag in the mesh box needs to be picked up and cleaned by personnel, which is time-consuming and labor-intensive. The mesh box in the device is inconvenient to disassemble and clean, which affects the subsequent heat treatment of the sun gear shaft forging. Improvement and optimization are needed.

[0004] Therefore, this utility model proposes a heat treatment device for finished sun gear shaft forgings to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a heat treatment device for finished sun gear shaft forgings to solve the problems mentioned in the background art.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The mesh cage is lifted by engaging the ball bearings in the arc groove of the first mounting block with the mounting post, and then fastening the spring hook at the end of the wire rope to the lifting ring.

This completes the installation of the mesh cage. The operation is simple, allowing for quick assembly and disassembly of the mesh cage. It facilitates the removal of quenching residue from the mesh cage, improves the cleaning efficiency of the mesh cage, and avoids affecting the subsequent heat treatment of the sun gear shaft forging.
