Description

Technical Field

[0001] This utility model relates to the field of metal heat treatment technology, specifically to an oil quenching device for mold steel samples. Background Technology

[0002] Quenching and tempering is a heat treatment process that includes two steps: quenching and high-temperature tempering. Quenching gives the die steel a high-hardness martensitic structure, but also increases its brittleness. Subsequent high-temperature tempering eliminates quenching stress and spheroidizes carbides, thus achieving good toughness while maintaining high strength. This treatment method achieves a balance of strength and toughness through microstructural transformation, resulting in workpieces with both high strength and good plasticity and impact toughness.

[0003] During the conditioning process of mold steel samples, oil quenching is usually required. After the sample is heated, it is placed in quenching oil. The temperature of the quenching oil around the sample rises sharply, while the temperature of the quenching oil further away from the sample is relatively low. This results in poor oil quenching effect and affects the quality of the mold steel conditioning process. Utility Model Content

[0004] The purpose of this invention is to provide an oil quenching device for mold steel samples. During the oil quenching of mold steel samples, the quenching oil in the quenching tank is circulated to ensure the uniformity of its temperature and effectively guarantee the oil quenching quality of the mold steel samples.

[0024] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 2 As shown, an oil quenching device for mold steel samples in this embodiment includes a frame 1, a lifting device, and a placement frame 2.

[0026] like Figure 1 As shown, the lower part of the frame 1 is provided with a quenching pool 3, which carries quenching oil; the frame 1 is provided with an oil pump 4, and the inlet and outlet of the oil pump 4 are respectively extended into the quenching pool 3 through pipes 5.

[0027] The lifting device is located at the top center of the frame 1;

[0028] The placement frame 2 is located inside the quenching tank 3. The placement frame 2 is provided with a frame body 6, and the placement frame 2 is connected to the lifting end of the lifting device through the frame body 6.

[0029] During oil quenching of the mold steel sample, the sample is placed into the placement frame 2 using a tool. The oil pump 4 is then started, and the quenching oil in the quenching tank 3 is continuously circulated under the action of the oil pump 4. The placement frame 2 is lowered by a lifting device until the mold steel sample is completely immersed in the quenching oil for quenching. Then, the placement frame 2 is raised again by the lifting device to complete the oil quenching of the mold steel sample. The oil pump 4 ensures that the quenching oil in the quenching tank 3 is continuously circulated, maintaining a uniform temperature and ensuring the quality of the oil quenching.

[0030] In this embodiment, the oil pump 4 is equipped with filter screens (not shown in the figure) at both the inlet and outlet, which effectively prevents impurities from entering the oil pump 4 and causing damage to it.

[0031] In this embodiment, as Figure 3 As shown, the lifting device includes a nut 7, a lead screw 8, and a motor 9; the nut 7 is horizontally and rotatably mounted on the top of the frame 1; the motor 9 is used to drive the nut 7 to rotate; the lead screw 8 is vertically mounted and sleeved on the nut 7, and the bottom of the lead screw 8 is fixed to the frame 6; with this configuration, the motor 9 drives the nut 7 to rotate, thereby realizing the rise or fall of the lead screw 8, and ultimately realizing the lifting and lowering of the placement frame 2.

[0032] Furthermore, in this embodiment, guide rods 10 are vertically fixed on the inner walls of both sides of the frame 1; both sides of the frame 6 are provided with sleeve parts 11, and the frame 6 is slidably sleeved on the two guide rods 10 through the sleeve parts 11 on both sides; this arrangement effectively ensures the stability of the lifting and lowering of the placement frame 2.

[0033] In this embodiment, the output end of the motor 9 is connected to a reduction gearbox 12. This configuration allows for precise control of the rotational speed of the nut 7, resulting in a more stable lifting and lowering of the placement frame.

[0034] The quenching tank 3 is also equipped with several heating rods 13, which are electrically connected to an external power source. In cold weather, the quenching oil can be heated to the normal temperature through the heating rods 13 to ensure the effectiveness of quenching the mold steel sample.
