Description
Technical Field
[0001] This utility model relates to the field of rolling mill brackets, and more particularly to a steel tapping bracket for a rolling mill. Background Technology
[0002] The steel tapping bracket of a cold rolling mill is used to conduct rolled steel plates, pipes and other steel materials, so that the rolled steel materials can be stably transported to the next processing step. Currently, the steel tapping brackets used rely on a series of rotating rollers to conduct and transport the steel materials.
[0003] To prevent the steel from shifting during transmission, it is necessary to laterally limit the transmission of the steel to ensure that it is conveyed in a straight line. Currently, blocking components are set on the surface of the roller or on both sides of the structure to ensure that the steel passes between the blocking components. However, the blocking components are fixed, resulting in a fixed gap size between the passing steel, which is not convenient to adjust the passing gap according to the specific steel size. Utility Model Content
[0004] To address the aforementioned problems, the purpose of this utility model is to provide a steel tapping bracket for a rolling mill, which solves the problem that the current steel tapping brackets have fixed blocking components, making it inconvenient to conveniently adjust the steel passage gap according to the specific dimensions of the rolled steel.
[0005] The technical solution of this utility model is as follows: A steel tapping bracket for a rolling mill includes a bed frame, on the surface of which a plurality of rotating rollers and limiting guide rollers are rotatably arranged, and the limiting guide rollers include a roller body, on the surface of which an axial groove is radially penetrated. Two limiting rings are symmetrically fitted on the surface of the roller body. The limiting rings are composed of two symmetrical semi-rings. The inner side of the semi-rings has an insertion part. The insertion part is slidably inserted into the axial groove to restrict the semi-rings from sliding linearly along the axial direction of the roller body. The two insertion parts are tightened by screws so that the two semi-rings hug the roller body.
[0006] Preferably, the insertion part includes a tongue plate, which is fixed to the inner wall of the semi-ring split. A wedge block is provided on the surface of the tongue plate. The middle part of the axial groove is a uniform width part, and the two ends are flared parts. The two sides of the wedge block are parallel to the inner wall of the flared part. The screw passes through one wedge block and is threadedly connected to another wedge block. The screw is used to pull the two wedge blocks close together and tightly against the inner wall of the flared part. A sliding groove is opened on the surface of the tongue plate. The wedge block is slidably disposed in the sliding groove. A spring piece for pushing the wedge block is provided at the bottom of the sliding groove.
[0007] Preferably, the two side walls of the flared portion and the two side surfaces of the wedge block are both rough toothed surfaces; the thickness of the tongue plate is adapted to the width of the equal width portion; the inner wall of the semi-ring split is provided with a rubber layer; and two sets of position marks are symmetrically arranged along the axial groove on the surface of the roller body.
[0008] Preferably, the semi-ring split includes a shell and a blocking part, and the blocking parts of the two limiting rings are distributed facing each other to form a gap that restricts the conduction of steel.
[0009] Preferably, the blocking portions of the two semi-ringed parts are joined together to form a disk shape, which is used to conduct steel that is plate-shaped or has a polygonal cross-section.
[0010] Preferably, the blocking portions of the two semi-ringed parts are fitted together to form a frustum shape, which is suitable for conducting and limiting the movement of circular tubular steel.
[0011] The beneficial effects of this utility model are as follows: 1. This utility model has two limiting rings symmetrically and linearly sliding on the surface of the roller to conduct and limit the movement of the steel. The limiting ring is composed of two half-rings tightened by screws. Loosening the screws can slide and adjust the distance between the two limiting rings. Tightening the screws makes the half-rings hug the roller for positioning. The passage gap of the steel can be conveniently adjusted according to the specific size of the rolled steel.
[0012] 2. The screw of this utility model penetrates and tightens the wedge block, so that the two semi-rings separately hug the roller body, while the wedge block is tightly attached to the inner wall of the flared part, realizing double tight fixing and ensuring that the limiting ring can stably restrict the transmission of steel.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Example 1, as Figure 1 As shown, the steel tapping bracket of the rolling mill includes a bed frame 1, on which several rotating rollers 2 and limiting guide rollers 3 are arranged and rotatably mounted. The limiting guide rollers 3 are spaced apart. The steel tapping bracket provided in this application is a non-powered bracket, but it can also be combined with a motor and chain to drive the rotating rollers 2 to form a driven bracket.
[0023] like Figure 2 , Figure 3 As shown, the limiting guide roller 3 includes a roller body 31. An axial groove 32 is formed on the surface of the roller body 31, and the axial groove 32 radially penetrates the roller body 31. Two limiting rings 4 are symmetrically arranged on the surface of the roller body 31. The limiting rings 4 are composed of two symmetrical semi-rings. An insertion part is provided on the inner side of the semi-ring. The insertion part is slidably inserted into the axial groove 32, which can restrict the semi-rings from sliding linearly along the axial direction of the roller body 31. The two insertion parts are connected by screws 5. Two sets of position marks 33 are symmetrically arranged on the surface of the roller body 31 along the axial groove 32. The limiting rings 4 are moved along the surface of the roller body 31 by loosening the screws 5. The distance between the two limiting rings 4 is adjusted to the set size by the corresponding position marks 33. Then the screws 5 are tightened to pull the two insertion parts tight, so that the two semi-rings hug the roller body 31 for positioning, thus completing the adaptive adjustment of the transmission gap size.
[0024] The semi-ring split includes a housing 41 and a blocking part 42. The blocking parts 42 of the two limiting rings 4 are distributed facing each other to form a gap that restricts the conduction of steel. The blocking parts 42 of the two semi-ring splits are fitted together to form a frustum shape, which is suitable for limiting the conduction of round tubular steel.
[0025] The insertion part includes a tongue plate 43, which is fixed to the inner wall of the semi-annular split housing 41. A wedge block 44 is provided on the surface of the tongue plate 43. The middle part of the axial groove 32 is a constant width part 321, and the two ends are flared parts 322. The two sides of the wedge block 44 are parallel to the inner wall of the flared part 322. The thickness of the tongue plate 43 is adapted to the width of the constant width part 321. Screw 5 passes through one wedge block 44 and is threadedly connected to another wedge block 44. Tightening screw 5 pulls the two wedge blocks 44 together. When the two semi-rings are driven to hug the roller body 31, the two sides of the wedge block 44 are pressed against the inner wall of the flared part 322, achieving double locking and positioning.
[0026] like Figure 4 , Figure 5 , Figure 6 As shown, a groove 45 is opened on the surface of the tongue plate 43. The groove 45 extends through the two side walls of the flared part 322. The wedge block 44 is slidably disposed in the groove 45. The thickness of the wedge block 44 in the axial direction of the roller body 31 is adapted to the groove 45. A spring piece 46 is fixed at the bottom of the groove 45. The spring piece 46 applies a spring force to the wedge block 44 in the direction of the semi-circular split.
[0027] When the fastening screw 5 tightens the two wedge blocks 44, the wedge blocks 44 abut against the spring piece 46, causing the two semi-ring parts to come together. After the semi-ring parts come together, the fastening screw 5 continues to compress the spring piece 46 relative to the slide groove 45, forming an elastic pressing method, which can coordinate the semi-ring parts to hug the roller body 31 and the wedge blocks 44 to stick to the flared part 322.
[0028] Both sides of the flared portion 322 and both sides of the wedge block 44 are rough toothed surfaces, which increases the friction when the wedge block 44 and the flared portion 322 are pressed together, and further improves the positioning strength of the limiting ring 4.
[0029] The inner wall of the semi-ring split is provided with a rubber layer 6, which can improve the strength of the semi-ring split clamping roller 31.
[0030] Example 2, as Figure 7 As shown, the difference from Embodiment 1 is that the two semi-ringed blocking parts 42 are joined together to form a disc shape, which is used to conduct steel in the form of a plate or a polygonal cross section.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
