Embodiment 1

[0019] Embodiment 1: see Figure 4 , a new type of air-pass rolling mill motor sealing device, the sealing device includes an inner slip ring 1 and an outer slip ring 6, a first O-ring 2 and a second O-ring 7, a double-lip seal ring 5, and an eccentric disc 9 , the double-lip sealing ring and the second O-ring are set on the eccentric disk 9, the first O-ring is set in the groove of the inner slip ring 1, and the first O-ring is set on the outer slip ring 6 The sealing device also includes a static sealing ring 10 which is arranged on the upper surface of the outer sliding ring 6 . The overall structure of the sealing device is ingeniously and compactly designed, and a static sealing ring is added, which can meet the rolling requirements of the wire rod mill being empty and the motor is disabled, ensuring that the cooling water of the finishing mill does not enter the thin oil station to pollute the lubricating oil, and stop the relevant Corresponding to the rolling motor to ...

Embodiment 2

[0020] Example 2: see figure 1 , figure 2 , image 3 , Figure 4 , as an improvement of the present invention, an upper O-ring groove 14 is arranged on the top of the static sealing ring 10, and a lower O-ring groove 15 is arranged on the lower side of the static sealing ring; the sealing device also includes an upper O-ring groove 14; Type ring 11 and lower O-ring 12, the upper O-ring 11 is set in the upper O-ring groove 14; the lower O-ring 12 is set in the lower O-ring groove 15, and the O-ring and the O-ring groove are mutually Fit seal. Thereby, the double-lip seal can be completely isolated from external cooling water, iron oxide scale and other sundries, so that the purpose of saving electric energy can be achieved. The rest of the structures and advantages are exactly the same as in Embodiment 1.

Embodiment 3

[0021] Embodiment 3: see Figure 4 , as an improvement of the present invention, the sealing device also includes a splayed plate 8, the splayed plate 8 is arranged on the surface of the rolling mill box 13, and is bonded to the mating surface of the eccentric disc 9 through the second O-ring 7; The above-mentioned sealing device also includes a hollow protective cap 4, which is arranged on the static sealing ring 10, and the protective cap is pressed tightly by the locking bolt, so that the upper O-ring 11 and the lower O-ring 12 are deformed, and cling to the empty protective cap 4 and the eccentric disc 9 respectively, so that all parts that may enter the water can be sealed in place, so that the double lip sealing ring 5 is completely isolated from the external cooling water and iron oxide scale and other sundries To prevent iron oxide from accumulating under the lips of the double-lip seals, and prevent water ingress and aging at the position of the double-lip seals in th...

Abstract

The invention relates to a novel motor sealing device for an idle rolling mill. The novel motor sealing device for the idle rolling mill is characterized in that the sealing device comprises an inner sliding ring, an outer sliding ring, a first O-shaped ring, a second O-shaped ring, a double-lip sealing ring, an eccentric disc, an upper O-shaped ring, a lower O-shaped ring and a static sealing ring, the double-lip sealing ring and the second O-shaped ring are arranged on the eccentric disc, the first O-shaped ring is arranged in a groove of the inner sliding ring, the first O-shaped ring is arranged in a groove of the outer sliding ring and is tightly attached to a matching surface of the inner sliding ring, and the upper O-shaped ring and the lower O-shaped ring are arranged in an upper O-shaped ring groove and a lower O-shaped ring groove of the static sealing ring respectively. The novel motor sealing device for the idle rolling mill is ingenious in overall design and compact in structure and overcomes the defects of sealing devices in the prior art; by the adoption of the sealing device, ferric oxide can be prevented from accumulating below the double-lip sealing lip edge, water is prevented from entering the double-lip sealing position in a roller box, aging of the double-lip sealing position in the roller box is prevented, the situation that cooling water enters lubricating oil to caused oil pollution is avoided, a motor for the corresponding rolling step can be stopped, power consumption is reduced, and production cost is greatly reduced.

Description

technical field [0001] The invention relates to a sealing device, in particular to a novel motor sealing device for an empty rolling mill, belonging to the technical field of empty rolling mill equipment. Background technique [0002] In the prior art, many wire rod factories use American Morgan "8+4" rolling mills to roll high-speed wire rods, that is, 8 φ230 finishing mills and 4 (2xφ230+2xφ150) reducing and sizing mills, with a total of 30 rolling mills. System passes. When rolling φ14.5mm-φ26mm wire rods, the 19-26 finishing mills are all in the no-load state. During the production process, only empty conduits need to be installed, and the incoming materials directly enter the 27-30 from the 15-16 rolling mills. The frame reducing and sizing unit rolls out finished products. In addition, when rolling φ12mm-φ26mm specifications, the 17-18 rolling mills are all empty. When the motor is directly stopped, the oxide scale will accumulate in the narrow space between the out...
