Description

Technical Field

[0001] The utility model relates to the field of metallurgical processing equipment, in particular to a roller quenching rotating device. Background Art

[0002] Roller development in the workshop involves quenching the rolls, which includes air spray quenching. This involves heating the roll surface to 950°C, removing it from the furnace, and then subjecting it to air spray quenching. Existing techniques typically remove the rolls and place them overhead, where they are then cooled using a refrigeration system. This approach fails to ensure uniform cooling across all parts of the roll during air spray quenching.

[0003] Therefore, it is necessary to develop a roll quenching rotating device. Utility Model Content

They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation.

[0028] like Figure 1-6 As shown, a roller quenching rotation device includes a carrier plate 1 and a hook 2, the hook 2 is fixed to the carrier plate 1, and at least two mounting seats 3 are provided on the top of the carrier plate 1. The top of each mounting seat 3 is provided with two symmetrically distributed grooves 4, and the top of the mounting seat 3 is fixedly connected to support plates 5 at positions on both sides of the groove 4. A roller 6 is rotatably connected between the two opposing support plates 5. Through openings 7 penetrating the grooves 4 are provided on both sides of the mounting seat 3, and the grooves 4 and the bottom walls of the through openings 7 are connected to form a smooth inclined structure;

[0029] During operation, the roller quenching rotary device cooperates with an external refrigeration mechanism (such as a spray fan) to work. After the rollers are heated and taken out of the furnace, they are hoisted and placed on the rotating fixture of the roller quenching rotary device provided by the utility model. The spray fan is turned on, and the rollers spray and blow air while rotating to achieve a uniform cooling effect on the entire roller.

[0030] In order to realize the rotation of the rotary tooling, a driving motor 8 is fixedly connected to the outer wall of one of the mounting seats 3, and the output shaft of the driving motor 8 is connected to the driving gear 9. The end of the axis rod of one of the rollers 6 is fixedly connected to the driven gear 10, and the driving gear 9 is meshed with the driven gear 10 for transmission. The axis rods of the two rollers 6 on the mounting seat 3 where the driven gear 10 is located are fixedly connected with sprockets, and the chain 11 is chain-connected between the two sprockets. The driving gear 9 is driven by the output shaft of the driving motor 8, and the driven gear 10 is further meshed to rotate the corresponding roller 6. Under the cooperation of the sprocket and the chain 11, the two rollers 6 on the same mounting seat 3 rotate in the same direction, which has a rolling and flipping effect on the contact friction of the rollers placed on the rotary tooling.

[0031] Specifically, the bottom of both sides of the mounting seat 3 are fixedly connected with ribs 12 that fit with the supporting plate 1, which can improve the stability of the mounting seat 3 when placed. A plurality of threaded holes 13 distributed in a linear array are provided on the surface of the supporting plate 1. Positioning holes that match the positions of the threaded holes 13 are penetrated on the ribs 12. Bolts 14 are inserted into the positioning holes, and the bottom ends of the bolts 14 are threadedly connected to the threaded holes 13, which facilitates the adjustment and installation of the mounting seat 3, realizes the adjustability of the spacing of the rotating tooling, and is suitable for use with rollers of different lengths.

[0032] Specifically, a slide rail 15 is fixedly connected to the supporting plate 1, and a slide groove 16 matching the slide rail 15 is provided on the mounting seat 3. When the mounting seat 3 is placed on the supporting plate 1, multiple slide rails 15 are matched one-to-one with multiple slide grooves 16 to prevent the mounting seat 3 from deviating or sliding sideways, thereby achieving stable adjustment of the mounting seat 3.

[0033] Specifically, the hook 2 is located on the slide rail 15 , and the top wall of the slide groove 16 matches the top end of the hook 2 . The hook 2 can pass through the slide groove 16 without hindering the sliding of the mounting seat 3 .

[0034] Specifically, the number of hooks 2 is set to four, and the four hooks 2 are symmetrically distributed about the center axis of the load-bearing plate 1, and cooperate with the counterweight blocks movably arranged on the load-bearing plate 1, and the counterweight blocks are also locked on the load-bearing plate 1 by bolts 14. By increasing the number and installation position of the counterweight blocks, the load-bearing plate 1 can maintain gravity balance after carrying the rolling mill. When the four hooks 2 and the traction rope are used to lift the entire device, the load-bearing plate 1 can maintain horizontal transportation.

[0035] Specifically, the width of the groove 4 is greater than the diameter of the roller 6, so that impurities on the roller fall into the groove 4 after falling off and are discharged through the opening 7, thereby achieving the purpose of automatic cleaning and discharge.

[0036] Specifically, a pad 17 is fixedly connected to the bottom of the supporting plate 1 to reduce the loss of the supporting plate 1 and extend the service life of the device.

[0037] When the device is in use, the rollers that have been heated and taken out of the furnace are hoisted and placed on the rotating tooling, that is, between the two rollers 6 on the multiple groups of mounting seats 3, and the driving motor 8 is started so that its output shaft drives the active gear 9, which further engages the driven gear 10 to rotate the corresponding roller 6. Under the cooperation of the sprocket and the chain 11, the two rollers 6 on the same mounting seat 3 rotate in the same direction, which has a rolling and flipping effect on the contact friction of the rollers placed on the rotating tooling. At this time, the device cooperates with the external refrigeration mechanism (such as a spray fan) to work. When the spray fan is turned on, it rotates and sprays air at the same time to achieve a uniform cooling effect on the entire roller. During the cooling process, the oxide layer or impurities on the surface of the roller will fall off. In order to avoid accumulation in the groove 4 to form friction resistance to the movement of the roller 6, a through port 7 is provided to allow the impurities to be discharged, thereby achieving the purpose of automatic cleaning and discharging.

[0038] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
