Description

Technical Field

[0001] The utility model relates to the technical field of spring steel wire production, in particular to oil quenching equipment for spring steel wire production. Background Art

[0002] Oil quenching is a process in the steel wire forming process. It is suitable for use in ordinary mechanical springs. Oil quenching and tempering treatment is also called quenching and tempering heat treatment. The production process of oil quenching and tempering spring steel wire is characterized by quenching and tempering the steel wire that is cold drawn to the specified size. The treated steel wire has a tempered troostite structure, good strength and toughness, high fatigue limit, and good thermal stability. It is significantly better than traditional cold-drawn spring steel wire and is an ideal material for manufacturing automobile valve springs and suspension springs.

[0003] Patent publication number CN211445817U proposes an oil tank for oil quenching of high-performance spring steel wire, including a quenching tank and an oil storage tank located below the quenching tank, and grid plates are provided at both ends of the quenching tank. The steel wire passes through the pores of the grid plate and the quenching tank. A plurality of oil inlets are provided on one side of the quenching tank and an oil outlet is provided on the side of the oil storage tank. The quenching tank and the oil storage tank are connected by a connecting pipe, and a pump body is provided on the connecting pipe. The connecting pipe includes an upper main pipe at the top and a lower oil outlet pipe at the bottom. The upper main pipe is connected to the oil inlet through a plurality of branch pipes, and the lower oil outlet pipe is connected to the oil outlet in the same connection mode. The modular design is adopted to facilitate the installation and disassembly of the oil tank, and also to facilitate the recycling of the oil body and the effective quenching of the steel wire. This structure has the following shortcomings in actual use: quenching oil will remain on the surface of the steel wire after oil quenching. At this time, directly moving the steel wire out of the quenching tank will cause a waste of quenching oil. At the same time, when quenching the steel wire, the oxide layer on the surface of the steel wire will cool and peel off, resulting in an increase in impurities in the quenching oil. For this reason, we provide an oil quenching equipment for spring steel wire production. Utility Model Content

A hook 41 is connected to the top of the loading hook 4, and the hook 41 matches the cross bar 3. A handle 42 is connected to the side of the loading hook 4.

[0024] See also Figure 2 , Figure 3 , Figure 6An oil filter tank 5 is welded on the top of the quenching tank 1. The oil filter tank 5 is in an L-shaped structure. An oil leakage hole 51 is opened at the bottom of the oil filter tank 5. By setting the oil filter tank 5, the spring steel wire after quenching is placed on the oil filter tank 5 for oil control to reduce the waste of quenching oil. A slope 6 is set at the bottom of the quenching tank 1. The slope 6 is inclined downward toward the filter tank 8. By setting the slope 6, impurities precipitated in the quenching oil can flow to the filter tank 8. The bottom of the slope 6 is connected to a plurality of heat sinks 7 distributed at equal intervals. By setting the heat sink 7, the heat sink 7 can be increased. The contact area of ​​the air is increased to improve the cooling of the quenching oil and avoid the quenching oil from being too high in temperature. The side of the bottom of the quenching tank 1 is connected to a filter tank 8, and the interior of the filter tank 8 is connected to a filter core 81. The top of the filter tank 8 is fixedly connected to a pump body 9. By setting the filter tank 8, the pump body 9 is used to transport the quenching oil for circulation, and the filter core 81 inside the filter tank 8 is used to filter the quenching oil, which can remove impurities in the quenching oil and improve the quality of the quenching oil. The top of the pump body 9 is fixedly connected to a spray head 10, and the spray head 10 is fixedly installed on the side of the quenching tank 1.

[0025] See also Figure 1 , Figure 3 The spray head 10 is located at the bottom of the oil filter tank 5. When the spray head 10 sprays the quenching oil, the airflow blown to the spring steel wire can cool the quenching oil at the same time and reduce the temperature of the quenching oil. A fan 11 is installed on the side of the quenching tank 1. A blowing pipe 12 is fixedly connected to the top of the fan 11. The blowing pipe 12 is L-shaped and extends to the top of the oil filter tank 5. A blowing hole 13 is opened at the bottom of the blowing pipe 12. The fan 11 is used to transport air into the blowing pipe 12, and then the blowing hole 13 is used to blow air to the spring steel wire.

[0026] In summary, when the oil quenching equipment for spring steel wire production is used, the quenching oil is poured into the quenching tank 1, and the loading hook 4 is used to lift the spring steel wire and immerse it in the quenching oil for quenching. During quenching, the loading hook 4 is placed on the cross bar 3 to store the spring steel wire in the quenching oil for a period of time. After quenching, the spring steel wire is placed on the oil filter tank 5 for oil control. During oil control, air is transported to the air blowing pipe 12 through the fan 11, and then the blowing hole 13 blows air to the spring steel wire to accelerate the dripping of the quenching oil on the surface of the spring steel wire and accelerate the cooling of the spring steel wire. The quenching oil at the bottom of the quenching tank 1 is transported to the spray head 10 through the pump body 9 for spraying, so that the quenching oil can circulate, and the sprayed quenching oil can also be cooled by the blown air to reduce the temperature of the quenching oil. The filter tank 8 can filter the quenching oil to remove impurities.
