Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment and quenching of metal parts, in particular to heat treatment and quenching equipment for metal parts. Background Art

[0002] Quenching is a heat treatment process in which a metal part is heated to above a critical temperature, kept at that temperature for a certain period of time, and then cooled at a rate greater than the critical cooling rate to obtain an unbalanced structure dominated by martensite. In the quenching process of existing metal components, the heated metal part is directly placed in a prepared cooling liquid to achieve rapid cooling. During the cooling process, debris on the surface of the metal part will enter the cooling liquid. The debris will exist in the cooling liquid for a long time in the state of a single substance or ion. If it is not cleaned in time, the floating single substance or metal ions will affect the properties of the cooling liquid, and the denatured cooling liquid will affect the quenching effect of the metal part.

[0003] In view of the above problems, the present utility model is proposed. Utility Model Content

One end of the liquid inlet pipe 14 is threadedly connected to the outlet of the liquid pump 13, and the other end faces the mouth of the liquid barrel 1. Valves 121 are provided on the inlet and outlet of the filter 12. The coolant can pass through the filter 12, then enter the liquid inlet pipe 14, and then flow into the liquid barrel 1;

[0028] The inner wall of the liquid barrel 1 is provided with four support blocks 17, and the four support blocks 17 are located on the same horizontal plane. The four support blocks 17 are arranged in a circumferential shape at equal intervals on the inner wall of the liquid barrel 1. The support plate 2 is placed on the support blocks 17. The upper surface of the support plate 2 is evenly provided with a plurality of through holes 21 penetrating the support plate 2. The upper surface of the support plate 2 is also symmetrically provided with two first handles 22. The support blocks 17 support the support plate 2.

[0029] A bottom plate 23 is movably mounted on the inner bottom surface of the liquid barrel 1, and a plurality of electromagnets 24 are arranged on the bottom plate 23. A second handle 25 is also symmetrically arranged on the upper surface of the bottom plate 23. When the electromagnet 24 works, it can absorb the metal elemental impurities in the coolant to ensure that the coolant above the support plate 2 is relatively clean.

[0030] It also includes a first clamping ring 15 and a second clamping ring 16. Multiple first clamping rings 15 are installed on the surface of the liquid barrel 1 by bolts. The vertical part of the liquid inlet pipe 14 passes through the first clamping ring 15. Two second clamping rings 16 are installed on the upper surface of the liquid pump 13 by bolts. The horizontal part of the liquid inlet pipe 14 passes through the second clamping ring 16.

[0031] The first handle 22 is arranged on both sides of the upper surface of the support plate 2, and the through hole 21 is in a runway circle shape, that is, the through hole 21 has a certain area, so that metal single substance magazines can pass through the through hole 21 smoothly and the through hole 21 is not easily blocked.

[0032] A plurality of first clamping rings 15 are installed on the surface of the liquid barrel 1 at equal intervals from bottom to top, and the inner surfaces of the first clamping rings 15 and the inner surfaces of the second clamping rings 16 are both in contact with the surface of the liquid inlet pipe 14 .

During the quenching process, impurities and debris dropped by the metal piece remain in the coolant. The electromagnet 24 can absorb the metal impurities in the elemental state, thereby preventing the impurities from remaining in the upper layer of the coolant. When one metal piece is quenched and another metal piece is placed, the impurities will not contact the quenched metal piece, thereby ensuring the quenching quality of the metal piece.

[0037] As the cooling liquid circulates, impurities in ionic state can be adsorbed by the filter 12 when passing through the filter 12, so that the impurities in ionic state will not come into contact with other quenched metal parts; through adsorption and filtration, the cooling liquid above the support plate 2 can be kept relatively clean, so that when the metal parts are quenched on the support plate 2, they can come into contact with relatively clean cooling liquid, and the quenching effect is better.
