Description

Technical Field

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

[0002] Steel tempering refers to a double heat treatment method of quenching and high-temperature tempering of steel. Its purpose is to make the steel have good comprehensive mechanical properties. During the tempering process of steel, the steel needs to be quenched first, then cooled to a certain temperature and then tempered at high temperature.

[0003] According to the steel heat treatment and tempering equipment provided by application number CN202322732970.8, a rotating nozzle is used instead of a fixed nozzle. When treating the steel, the rotating nozzle can evenly spray water to cool the steel; after the cooling water is recovered to the inside of the first cooling tank, the second cooling tank and the third cooling tank, it is cooled by the semiconductor refrigeration plate and the stirring plate driven by the motor to stir and dissipate heat, which can ensure the cooling effect of the cooling water.

[0004] It can be seen from the above-mentioned literature that the rotary nozzle assembly is arranged up and down, and can effectively spray and cool round steel. However, in actual processing, the shape of steel is square and round. When the rotary nozzle sprays square steel, it can only spray the upper and lower surfaces of the square steel, and cannot effectively spray and cool the surrounding areas, which has certain limitations.

[0005] Based on this, it is necessary to propose a steel heat treatment and tempering equipment. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , a steel heat treatment and tempering equipment, including an equipment body 1:

[0033] The upper part of the interior of the device body 1 is connected to a semi-arc-shaped connecting pipe 1 2, and the lower part of the interior of the device body 1 is connected to a semi-arc-shaped connecting pipe 2 210. The inner sides of the semi-arc-shaped connecting pipe 1 2 and the semi-arc-shaped connecting pipe 2 210 are both provided with a nozzle 220;

[0034] A water tank 4 is provided on the lower surface of the equipment body 1, and the interior of the water tank 4 is provided with a placement tank 1 410 and a placement tank 2 420. A diversion pipe 230 is connected to one side of the semi-arc connecting pipe 1 2 and the semi-arc connecting pipe 2 210. A connecting pipe 1 240 is connected to the diversion pipe 230. The other end of the connecting pipe 1 240 extends into the interior of the placement tank 1 410, and the extended end of the connecting pipe 1 240 is connected to a water pump 250.

[0035] During use, first, when the steel enters the interior of the equipment body 1, the cooling water inside the placement tank 410 is pumped out through the work of the water pump 250. At this time, the connecting pipe 1 240 cooperates to send the cooling water to the diversion pipe 230, and then the diversion pipe 230 sends it to the semi-arc connecting pipe 1 2 and the semi-arc connecting pipe 2 210, so that the nozzle 220 set on the semi-arc connecting pipe 1 2 and the semi-arc connecting pipe 2 210 can spray water on the surface of the steel, thereby cooling the steel. This partial structure can effectively cool square and round steels, broadening its scope of application.

[0036] As an optimal technical solution of the present invention, multiple groups of semi-arc connecting tubes 1 2 and semi-arc connecting tubes 2 210 are provided, and the multiple groups of semi-arc connecting tubes 1 2 and semi-arc connecting tubes 2 210 are staggered, and multiple groups of nozzles 220 are provided on the semi-arc connecting tubes 1 2 and semi-arc connecting tubes 2 210, and the multiple groups of nozzles 220 are distributed in a semi-arc shape at equal distances.

[0037] As a preferred technical solution of the present invention, an arc-shaped plate 3 is fixedly connected to the inner side wall of the equipment body 1 , and a plurality of groups of drain grooves 5 are opened on the other side of the interior of the equipment body 1 , and the plurality of groups of drain grooves 5 are directly opposite to the second placement groove 420 .

[0038] When the cooling water falls from the steel, the arc-shaped plate 3 can guide the cooled water to flow to the leakage groove 5, and then guide the cooled water to the inside of the placement groove 2 420 through the leakage groove 5.

[0039] As an optimal technical solution of the present invention, one side of placement tank 1 410 and one side of placement tank 2 420 are respectively connected with connecting pipe 3 440 and connecting pipe 2 430, and connecting pipe 3 440 and connecting pipe 2 430 are respectively connected to the water cooling treatment device.

[0040] When the amount of water inside the placement tank 1 410 is the same as the amount of water retained in the placement tank 2 420, the water in the placement tank 2 420 is sent to the water cooling treatment device through the connecting pipe 2 430 (the water cooling device there mainly cools the water through the operation of the semiconductor refrigeration plate). After the water is cooled, it flows back to the interior of the placement tank 1 410 through the connecting pipe 3 440 for continued use, thereby achieving the purpose of water recycling.

[0041] As an optimal technical solution of the present invention, slots 110 are provided on both sides of the device body 1, and supporting blocks 130 are fixedly connected on both sides of the device body 1. The interior of the supporting block 130 is movably connected to a movable block 140, and the upper end of the movable block 140 is connected to a conveying roller 120. Several groups of slots 150 are provided on the supporting block 130, and an insertion rod 160 is inserted into the interior of one group of slots 150, and the other end of the insertion rod 160 is inserted into the interior of the movable block 140.

[0042] When conveying different types of steel, the position of the movable block 140 is adjusted inside the supporting block 130, and the position of the adjusted movable block 140 is limited by the cooperation and insertion of the slot 150 and the insertion rod 160. At this time, the steel conveyed by the conveying roller 120 provided on the upper end of the movable block 140 can ensure that it is in the middle position of the slot 110 to ensure the subsequent cooling quality.
