[0043] First, the heat treatment device for metal material processing is installed at the position where it is needed. Then the staff fixes the quenching piece and first pulls the second mounting plate 307 upwards. The second mounting plate 307 slides upwards on the first connecting rod 305. At the same time, the second mounting plate 307 stretches the corresponding hydraulic telescopic rod 3012. Then, the quenching piece is placed on the limit block 3013 of the same group. In this process, first push the third connecting rod 3015 upwards. The third connecting rod 3015 drives the latch 3014 to move upwards, so that the latch 3014 slides upward from the limit groove 306b. The third connecting rod 3015 slides on the limit block 3013. Then, according to the size of the quenching piece, the limit block 3013 is pushed to slide in the slide groove 306a. Then, the third connecting rod 3015 is pressed. The third connecting rod 3015 drives the latch 3014 to move downwards, so that the latch 3014 enters the corresponding limit groove 306b to fix the The corresponding limit block 3013 is then pushed to move the second mounting plate 307 downward, and the second mounting plate 307 slides downward on the first connecting rod 305. The second mounting plate 307 drives the components connected thereto to move closer to the quenching piece placed on the limit block 3013, that is, drives the second connecting rod 308, the fourth connecting plate 309, the rolling wheel 3010 and the limit plate 3011 to move downward close to the upper surface of the quenching piece. When a through hole is provided in the middle of the quenching piece, the rolling wheel 3010 first contacts the upper surface of the quenching piece, and then in the process of further moving downward, the rolling wheel 3010 is limited by the quenching piece, so that the fourth connecting plate 309 rotates with the rotating shaft on the second connecting rod 308 as the rotation center, and the second connecting rod 308 drives the limit plate 3011 to rotate, so that the limit plate 3011 contacts the inner surface of the through hole of the quenching piece, fixes the quenching piece, and then fixes the quenching piece in the same way.

[0044] As mentioned above, this is a way to fix the quenched parts, which fixes the quenched parts to facilitate subsequent quenching work.

[0045] After the quenching part is fixed, use an external lifting equipment to first fix the pull ring on the first connecting rod 305, and drive the first connecting rod 305 to move into the limit frame 302. At the same time, the first connecting rod 305 is plugged into the second connecting plate 303. Then, use an external heating device to wrap the placement component 3, and then control the external heating device to heat the quenching part fixed on the placement component 3, so that the quenching part is heated to the quenching temperature. During this process, the liquid in the hydraulic telescopic rod 3012 expands due to the heating effect, pushing the second mounting plate 307 to slide upward on the outer surface of the first connecting rod 305. The second mounting plate 307 drives the components connected to it to move upward, so that the upper surface of the quenching part loses its limit, that is, the quenching part is blocked, so that the surface of the quenching part is completely heated, and part of the hot air heats the quenching part along the hole opened on the limit block 3013.

[0046] As described above, in order to allow the quenched part to be heated faster and more comprehensively, the method of reducing shielding is adopted to increase the heated area of ​​the quenched part. At the same time, the limit block 3013 is set in a wedge-shaped structure, that is, the contact area between the limit block 3013 and the quenched part is extremely small.

[0047] After the quenching part reaches the temperature required for quenching, the electric slider 204 is controlled to slide downward on the electric slide rail 203, and the electric slider 204 drives the first connecting plate 205 to move downward, and the first connecting plate 205 drives the first mounting plate 301 to move downward, and the first mounting plate 301 drives the limit frame 302 to move downward, and the limit frame 302 drives the components connected thereto to move downward, so that the quenching part moves downward into the quenching pool 201 for quenching. During this process, the quenching liquid passes through the hole provided on the second connecting plate 303, and at the same time passes through the fan 304, so that the fan 304 rotates to drive the quenching liquid to flow upward, so that the quenching liquid flows upward quickly and contacts the quenching part quickly, so that the quenching part is cooled quickly. During this process, the hydraulic telescopic rod 301 The second mounting plate 307 is driven downward by heat contraction, and the second mounting plate 307 drives the parts connected thereto to move downward and approach the quenching piece. First, the rolling wheel 3010 contacts the upper surface of the quenching piece. Then, in the process of further moving downward, the rolling wheel 3010 is limited by the quenching piece, so that the fourth connecting plate 309 rotates with the second connecting rod 308 as the rotation center. The fourth connecting plate 309 drives the limiting plate 3011 to rotate, so that the limiting plate 3011 contacts the inner surface of the quenching piece. At the same time, the rolling wheel 3010 rolls on the quenching piece, and the oxide scale on its upper surface is moved, so that the oxide scale on the surface of the quenching piece is quickly removed. Then, the pump 402 is controlled to flow the quenching liquid in the quenching pool 201 into the second connecting pipe 403 through the first connecting pipe 401, and By entering the third connecting pipe 404 and returning to the quenching pool 201 through the third connecting pipe 404, in this process, the first electromagnetic rod 408 and the second electromagnetic rod 4010 are controlled to be powered on, so that the first electromagnetic rod 408 and the second electromagnetic rod 4010 have magnetism, and the refluxed quenching liquid drives the detached oxide scale to flow, but when passing through the first electromagnetic rod 408 and the second electromagnetic rod 4010, the oxide scale is magnetically attracted and adsorbed on the surface of the first electromagnetic rod 408 and the second electromagnetic rod 4010, and at the same time, the third filter 4011 limits the oxide scale that is not magnetically adsorbed by the first electromagnetic rod 408 and the second electromagnetic rod 4010, and when the oxide scale accumulated on the first electromagnetic rod 408, the second electromagnetic rod 4010 and the third filter 4011 reaches a certain During quantitative measurement, the pump 402 is controlled to stop running, and then under the action of gravity, the first electromagnetic rod 408 slides downward on the second filter 407, and the first electromagnetic rod 408 drives the rubber plug 409 to move downward close to the third connecting pipe 404, so that the rubber plug 409 blocks the third connecting pipe 404, and then the electric valve 405 is controlled to operate, so that the third connecting pipe 404 is connected with the discharge pipe 406, and then the first electromagnetic rod 408 and the second electromagnetic rod 4010 are powered off, that is, the oxide scale loses its magnetic limit, and then the pump 402 is controlled to operate, and the quenching liquid is passed into the third connecting pipe 404 and flows out through the discharge pipe 406, and the flowing quenching liquid flushes the oxide scale remaining on the first electromagnetic rod 408, the second electromagnetic rod 4010 and the third filter 4011.At the same time, the quenching liquid that is trapped by the oxide scale is cleaned, and then the waste discharged from the discharge pipe 406 is collected.
