Description
Technical Field
The utility model belongs to the technical field of the hot rolling, especially, relate to a rolling mill rollgang guider.
Background
In the rolling process of the section bar, the section bar is generally required to be conveyed by a conveying roller way, and in order to ensure that the section bar longitudinally and linearly moves forward on the conveying roller way, a guide mechanism is generally installed on the conveying roller way, namely: and a guide plate is arranged on one side of the conveying roller way, and a guide roller is arranged on the other side of the conveying roller way. In the existing equipment, a certain gap generally exists between the lower end face of the guide roll and the conveying surface of the conveying roller way, so that when some special profiles such as angle steel and the like are rolled, the edge of the profile is easily clamped into the gap between the guide roll and the conveying surface of the conveying roller way, the surface of the profile is scratched, and the product percent of pass is reduced; in severe cases, the section bar can be stuck on the conveying track, which brings great hidden trouble to safety production.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem that exists, the utility model provides a rolling mill rollgang guider, the device simple structure, it is convenient to use, can prevent effectively that the edge of section bar from being blocked in the gap between guide roll and the rollgang transporting surface, has improved the product percent of pass, has ensured safety in production.
In order to achieve the above object, the present invention adopts the following technical solutions, including:
the conveying rollers are rotatably connected with the rack, and guide plates are arranged at the right ends of the conveying rollers and connected with the rack; a swing arm is arranged at the left end of the conveying roller, one end of the swing arm is rotatably connected with the rack, and the other end of the swing arm is rotatably connected with the guide roller; the outer side of the swing arm is connected with a connecting lug which is in pin connection with the end part of a piston rod of a push-pull oil cylinder, and the push-pull oil cylinder is connected with the rack; the guide roller is positioned between the adjacent conveying rollers, and the lower end face of the guide roller is lower than the tops of the peripheral surfaces of the conveying rollers.
The lower end surface of the guide roller is not less than 5 mm lower than the top of the peripheral surface of the conveying roller.
The swinging arm is rotatably connected with the guide roller, the other end of the swinging arm is connected with a [ -shaped connecting piece, the upper part of the connecting piece is rotatably connected with the upper end of a rotating shaft of the guide roller, and the lower part of the connecting piece is rotatably connected with the lower end of the rotating shaft of the guide roller.
The utility model relates to a rolling mill rollgang guider, the device simple structure, it is convenient to use, can prevent effectively that the edge of section bar from being blocked in the gap between guide roll and the rollgang transporting surface, improved the product percent of pass, ensured safety in production.

Detailed Description
In order to make the present invention more clearly understood by those skilled in the art, a brief description will be made on the roller way guiding device of the original rolling mill.
As shown in fig. 3, the roller table guiding device of the original rolling mill comprises: as can be seen from fig. 4, a gap h exists between the guide roller 14 and the conveying surface of the conveying track, and therefore, as shown in fig. 5, when the section angle steel 18 is rolled, the edge of the angle steel is easily clamped in the gap h, the edge of the section is scratched, the product quality is reduced, and even a production accident is caused.
The present invention will be described in further detail with reference to the accompanying drawings, as shown in fig. 1, the present invention includes:
the conveying rollers are rotatably connected with the frame, and the right ends of the conveying rollers are provided with guide plates 2 which are connected with the frame; a swing arm 3 is arranged at the left end of the conveying roller, one end of the swing arm is rotatably connected with the frame, and the other end of the swing arm is rotatably connected with a guide roller 4; the outer side of the swing arm is connected with a connecting lug 5, the connecting lug is in pin connection with the end part of a piston rod of a push-pull oil cylinder 6, and the push-pull oil cylinder is connected with the rack; the guide roller is positioned between the adjacent conveying rollers, and the lower end face of the guide roller is lower than the tops of the peripheral surfaces of the conveying rollers.
Preferably, the lower end surface of the guide roller is not less than 5 mm lower than the top of the outer peripheral surface of the conveying roller.
Preferably, the swing arm is rotatably connected with the guide roller, and a [ -shaped connecting member 7 is connected to the other end of the swing arm, the upper part of the connecting member is rotatably connected with the upper end of the guide roller rotating shaft, and the lower part of the connecting member is rotatably connected with the lower end of the guide roller rotating shaft.
In the rolling process, because the utility model discloses eliminated the gap between terminal surface and the rollgang transporting surface under the guide roll for when rolling such special section bar of angle steel, the edge of section bar can not blocked in also in the gap.
The utility model relates to a rolling mill rollgang guider, the device simple structure, it is convenient to use, can prevent effectively that the edge of section bar from being blocked in the gap between guide roll and the rollgang transporting surface, improved the product percent of pass, ensured safety in production.
