Description

Technical Field

[0001] The utility model relates to an anti-splash buffer device with a steel ball structure. Background Art

[0002] When a cold rolling mill is rolling strips (such as aluminum strips), rolling oil will be sprayed at the inlet of the cold rolling mill to play a role in lubrication and cooling. However, no rolling oil can splash onto the surface of the strip at the outlet of the cold rolling mill to avoid affecting the surface quality of the strip in subsequent processes. For this reason, an oil baffle is usually installed on the outlet side of the cold rolling mill. However, the oil baffle blocks the oil from the upper side. As for the left and right sides of the outlet of the cold rolling mill, the rolling oil is easy to splash along the guide rails and spray onto the arch frames on both sides. This not only causes a waste of rolling oil, but also the rolling oil particles will rebound after being sprayed onto the arch frames on both sides. The rebounded rolling oil particles will splash onto the surface of the strip, affecting the surface quality of the strip. Therefore, it is necessary to make improvements to the above technical problems, and this case is born out of this. Utility Model Content

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] Embodiment 1: Figures 1 to 3 As shown, the utility model is a steel ball structure splash buffer device, comprising a pair of fixed plates 100, the pair of fixed plates 100 are respectively arranged on the arch frames 101 on the left and right sides of the cold rolling mill outlet, and a plurality of steel balls 102 are fixed on the side of the fixed plate 100 facing the cold rolling mill outlet 104. During operation, when the rolling oil splashes out along the guide plate slide rail, the steel balls are used to prevent splashing and shield, and at the same time, the rolling oil can be buffered and blocked from being sprayed to the arch frames on both sides and rebounding the rolling oil particles, thereby reducing the oil content on the strip surface, thereby reducing the waste of rolling oil, which is beneficial to improving the environment.

[0025] In this embodiment, the fixed plate 100 is in a horizontal L-shape, and the long side of the fixed plate 100 extends along the rolling direction of the cold rolling mill. A plurality of steel wool balls 102 are arranged on a side of the long side of the fixed plate 100 facing the outlet end of the cold rolling mill. Furthermore, the steel wool balls can be locked to the long side of the fixed plate by fasteners, such as by bolts or rivets. It should be noted that, since the steel wool balls have a certain elasticity, when arranging the positions of the plurality of steel wool balls, the distribution method can be arbitrary, but the adjacent steel wool balls should be as close to each other as possible in an arc shape to reduce the blank area between the adjacent steel wool balls.

[0026] In this embodiment, for the convenience of connection, a connection hole is opened on the short side of the fixing plate 100, and a locking bolt 103 is passed through the connection hole for locking the short side of the fixing plate 100 to the archway frame. For example, the short side of the fixing plate is locked to the upper guide plate bracket of the archway frame on the same side by the locking bolt.

[0027] In this embodiment, a plurality of steel balls 102 are also fixed to a side of the long side of the fixing plate 100 facing the archway frame 101 on the same side, and the steel balls are located between the long side of the fixing plate and the archway frame on the same side.

[0028] The splash-proof buffer structure is composed of steel wool and fixed plates, which has low material cost, short production cycle, convenient installation and short time consumption. It can reduce the waste of rolling oil by shielding and buffering and reducing the oil content on the surface of the strip, which is beneficial to improving the environment.

[0029] Embodiment 2: Figure 1 , 4 -8, the difference between this embodiment and the first embodiment is that it also includes a mechanism for controlling the splashing of rolling oil on the surface of the cold rolling mill strip. Specifically: the mechanism for controlling the splashing of rolling oil on the surface of the cold rolling mill strip includes a cold rolling mill 1 and a roller 2 arranged on the cold rolling mill 1, and an oil baffle 3 is arranged on the side of the roller 2 to prevent the rolling oil from splashing, and the oil baffle 3 is fixedly connected to the first end of the guide rod 4, and the second end of the guide rod 4 is hinged to the first end of the swing arm 5, wherein a track 8 for limiting the sliding of the guide rod is provided on the frame, and the second end of the swing arm 5 is rotatably hinged on the frame of the cold rolling mill, and a hydraulic cylinder 6 is also installed on the frame of the cold rolling mill, and the free end of the telescopic rod 7 of the hydraulic cylinder 6 is hinged to the middle part of the swing arm, and an adjusting gasket structure A is provided on the hydraulic cylinder. When the telescopic rod 7 of the hydraulic cylinder 6 is extended, the swing arm 5 drives the guide rod 4 and the oil baffle plate 3 away from the roller 2. When the telescopic rod 7 of the hydraulic cylinder 6 is retracted, the swing arm 5 drives the guide rod 4 and the oil baffle plate 3 close to the roller 2.

[0030] In this embodiment, the adjusting gasket structure A includes a thin gasket A1 and a recessed groove A2 provided on one side of the thin gasket. The thin gasket and the recessed groove are coaxially arranged in a circular shape (of course, a square shape is also acceptable). The recessed groove A2 is sleeved on the hydraulic cylinder end head 601 (the hydraulic cylinder end head 601 is a position on the hydraulic cylinder body close to the telescopic rod 7). The thin gasket is provided with a through groove A3 for the telescopic rod of the hydraulic cylinder to pass through. The through groove A3 extends from the outer peripheral wall of the thin gasket A1 beyond its center part. The through groove is U-shaped, and the bottom of the through groove is arc-shaped. The through groove is matched with the telescopic rod of the hydraulic cylinder, so that the thin gasket A1 will not touch the telescopic rod.

[0031] In this embodiment, a tightening bolt A4 is threadedly connected to the thin gasket A1 and penetrates into the recessed groove A2 from its outer peripheral wall. The telescopic rod 7 of the hydraulic cylinder passes through the through groove A3. The inner end of the tightening bolt is pressed against the outer peripheral surface of the hydraulic cylinder end head 601, thereby fastening the thin gasket A1 and the hydraulic cylinder end head 601.

[0032] In this embodiment, when controlling different gaps between the oil baffle plate and the roller, thin gaskets A1 of different thicknesses are selected (the depth of the groove A2 is a fixed value), and the thickness of the thin gasket A1 minus the depth of the groove A2 is the basis for selecting the gap between the oil baffle plate and the roller; when rolling aluminum strips of different thicknesses and using rollers of different diameters, replacing thin gaskets A1 of different thicknesses can meet the function of adjusting the gap between the oil baffle plate and the roller.

[0033] In this embodiment, the working principle of the mechanism for controlling the rolling oil splashing on the surface of the cold rolling mill strip is to place the groove on the end head of the hydraulic cylinder and tighten it with a tightening bolt so that the inner end of the tightening bolt is pressed against the outer peripheral surface of the end head of the hydraulic cylinder, thereby realizing the fastening of the thin gasket and the end head of the hydraulic cylinder. When the telescopic rod of the hydraulic cylinder retracts, it is resisted by the thin gasket, so that the retraction stroke of the telescopic rod is limited, that is, the gap between the oil baffle plate and the roller is controlled. When a different gap between the oil baffle plate and the roller is required, it can be done by replacing thin gaskets of different thicknesses. Replacing thin gaskets of different thicknesses is convenient and quick, and the replacement cost is low.

[0034] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).

[0035] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0036] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated forming process.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
