Abstract
Description
Technical Field
[0001] This utility model relates to the field of quenching equipment technology, and more specifically, to a quenching equipment for heat treatment of stainless steel pipes. Background Technology
[0002] Stainless steel pipe heat treatment quenching is a process that involves heating the pipe to the austenitizing temperature (e.g., 1050-1100℃ for 304 steel) and holding it at that temperature to fully dissolve the carbides, followed by rapid cooling (water quenching, air cooling, etc.) to refine the grains and eliminate work hardening. This process can increase strength by 15%-30% and hardness by 2-3 HRC levels. At the same time, solution treatment prevents the precipitation of chromium carbide at grain boundaries, improving corrosion resistance by 20%-30%. It is suitable for high-pressure pipelines, chemical equipment, and other applications.
[0003] Most existing quenching devices use a spraying mechanism to quench stainless steel pipes. However, when the stainless steel pipes are sprayed, they remain stationary, which prevents them from being fully sprayed and reduces the quenching effect. To address this, we designed a stainless steel pipe heat treatment quenching device. Utility Model Content

[0006] As a preferred embodiment of this utility model, a groove plate is provided directly below the frame, and the support legs are installed inside the groove plate. A drain pipe is connected to one side of the bottom of the groove plate.

The support plate is fixed to one side of the support foot. A motor is installed above the support plate. A rotating shaft is connected to one side of the motor. One end of the rotating shaft is fixedly installed on the side wall of one of the gears.
[0009] As a preferred technical solution of this utility model, the spraying mechanism includes an upper frame and a water supply pipe. The upper frame is located directly above the frame.

The rotating mechanism can drive the multiple rollers 3 to rotate. The rotation of the multiple rollers 3 can drive the stainless steel pipe to move. The spraying mechanism sprays the stainless steel pipe, thereby quenching the stainless steel pipe.
[0019] The frame 1 has a groove plate 14 directly below it, and the support legs 2 are installed inside the groove plate 14. A drain pipe 15 is connected to one side of the bottom of the groove plate 14.

The groove plate 14 can collect the spilled water, and the drain pipe 15 can drain the water in the groove plate 14. The mounting plates 16 can facilitate the fixed installation of the groove plate 14.
[0020] The rotating mechanism includes multiple gears 5, a chain 6, and a support plate 7. The multiple gears 5 are respectively fixed to one end of multiple rotating rods 4. The chain 6 and the multiple gears 5 are configured to cooperate with each other. The support plate 7 is fixed to one side of the support leg 2. A motor 8 is installed on the top of the support plate 7. A rotating shaft is connected to one side of the motor 8. One end of the rotating shaft is fixedly installed on the side wall of one of the gears 5. Starting the motor 8 can drive the rotating shaft to rotate. The rotation of the rotating shaft can drive one of the gears 5 to rotate.

The rotating mechanism drives the multiple rollers 3 to rotate, which in turn drives the multiple stainless steel pipes to rotate. Then, the stainless steel pipes are sprayed by the spraying mechanism, thereby quenching the stainless steel pipes. By driving the stainless steel pipes to rotate through the rollers 3, the stainless steel pipes can be sprayed from all directions, increasing the quenching effect of the stainless steel pipes.
