Description

Technical Field

[0001] This utility model relates to the field of quenching equipment technology, and in particular to a quenching equipment with protective function. Background Technology

[0002] Quenching is a metal heat treatment process, primarily used for steel parts. It involves heating steel above a critical temperature, causing its microstructure to transform into austenite, and then rapidly cooling it, usually in water or oil, to transform the austenite into martensite. Martensite is harder than other microstructures in steel, so quenching can significantly improve the hardness and strength of steel. Quenching generally requires placing the steel part in a quenching apparatus for the operation.

[0003] In existing quenching devices, due to the high temperature of the steel parts, the quenching liquid is prone to boiling and splashing when placed in the quenching liquid, which can scald the operators. At the same time, the quenching liquid splashes out of the quenching tank, which will waste the quenching liquid. Utility Model Content

[0004] The technical problem to be solved by this utility model is that in the existing quenching device, because the temperature of the steel parts is very high, the quenching liquid is prone to boiling and splashing when placed in the quenching liquid, which can scald the operator. At the same time, the quenching liquid splashes out of the quenching pool, which will cause waste of the quenching liquid.

[0005] To solve the above technical problems, the present invention provides a quenching device with protective function, including an outer shell and a quenching frame. One end of the outer shell is provided with an opening. The quenching frame is slidably installed inside the outer shell. A threaded sleeve is fixedly connected between the two sides of the inner surface of the quenching frame. The end of the threaded sleeve near the outer shell extends through to one side of the outer surface of the quenching frame. A threaded rod is threadedly connected to the inner side wall of the threaded sleeve. One end of the threaded rod is rotatably connected to one side of the inner surface of the outer shell.

[0006] A protective shell is fixedly connected to one side of the outer shell surface, and a transmission component that drives the threaded rod to rotate is provided inside the protective shell.

[0007] Preferably, the transmission assembly includes a worm gear, one end of the threaded rod extends through to the outside of the outer shell and is fixedly connected to one side of the surface of the worm gear, a worm is provided on one side of the worm gear, the worm and the worm gear are meshed, and the upper and lower ends of the worm are rotatably connected to the inner top and inner bottom of the protective shell, respectively.

[0008] Preferably, a motor is fixedly installed on the top of the protective shell, and the output end of the motor extends through into the interior of the protective shell and is fixedly connected to the top of the worm gear.

[0009] Preferably, the outer side wall and bottom of the outer shell are provided with multiple round holes, and the bottom and outer side wall of the quenching frame are provided with multiple strip holes. The multiple round holes match the multiple strip holes, and the quenching liquid can enter the quenching frame from the round holes and strip holes.

[0010] Preferably, two limiting grooves are formed on both sides of the inner surface of the outer shell, and two limiting sliders are fixedly connected to both sides of the surface of the quenching frame, with the two limiting sliders slidably installed into the interior of the two limiting grooves respectively.

[0011] Preferably, the top of the outer casing is fixedly connected with multiple lifting rings around its perimeter for easy lifting.

[0012] Preferably, the bottom of the quenching frame is fixedly connected with multiple limiting posts to restrict the position of the steel parts inside the quenching frame.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention incorporates components such as a worm gear, worm wheel, threaded rod, and threaded sleeve. A motor drives the worm gear to rotate, and the worm gear meshes with the worm wheel, causing the worm wheel to drive the threaded rod to rotate. As the threaded rod rotates, it extends into the interior of the threaded sleeve, which can slide the quenching frame into the interior of the outer shell. During quenching, the outer shell, located outside the quenching frame, provides protection by preventing splashing caused by boiling when the steel parts inside the quenching frame come into contact with the quenching liquid, thus preventing injury and avoiding waste of quenching liquid.

The end of the threaded sleeve 3 near the outer shell 1 extends through to one side of the outer surface of the quenching frame 2. A threaded rod 4 is threadedly connected to the inner side wall of the threaded sleeve 3. One end of the threaded rod 4 is rotatably connected to one side of the inner surface of the outer shell 1.

[0022] like Figures 1 to 3 As shown, multiple limiting posts 11 are fixedly connected to the inner bottom of the quenching frame 2 to limit the position of the steel parts inside the quenching frame 2. Multiple lifting rings 10 are fixedly connected to the top of the outer shell 1 around the perimeter for easy lifting. Two limiting grooves are opened on both sides of the inner surface of the outer shell 1. Two limiting sliders 9 are fixedly connected to both sides of the surface of the quenching frame 2. The two limiting sliders 9 are slidably installed into the two limiting grooves. Multiple round holes 101 are opened through the outer wall and bottom of the outer shell 1. Multiple strip holes 201 are opened through the bottom and outer wall of the quenching frame 2. Multiple round holes 101 are opened through the outer wall and bottom of the quenching frame 2. 01 is matched with multiple strip holes 201, and quenching fluid can enter the quenching frame 2 through the round hole 101 and the strip holes 201. A motor 8 is fixedly installed on the top of the protective shell 5. The output end of the motor 8 extends through to the inside of the protective shell 5 and is fixedly connected to the top of the worm 7. The transmission component includes a worm wheel 6.

The motor 8 drives the worm 7 to rotate, and the worm 7 meshes with the worm wheel 6 to drive the worm wheel 6 to rotate. The worm wheel 6 drives the threaded rod 4 to rotate, and the threaded sleeve 3 drives the quenching frame 2 to slide into the outer shell 1 as the threaded rod 4 rotates. The outer shell 1 surrounds and protects the quenching frame 2. Then, the hook of the external lifting device is hung on the limiting post 11 to lift the entire device into the quenching pool for quenching. When the steel parts inside the quenching frame 2 come into contact with the quenching liquid, the quenching liquid boils, and the outer shell 1 can block the splashing quenching liquid.
