Description
Technical Field
The utility model belongs to the technical field of steel rolling equipment technique and specifically relates to rolling mill guide and guard device.
Background
On a section and wire rod rolling mill, a guide and guard device is a device which is arranged on a rolling mill frame and is positioned in front of and behind a roller, and a guide and support rolled piece between the rolling mill frames smoothly enters the rolling mill for rolling and is led out. The guide device is used for correctly guiding the rolled piece into the roll pass; ensuring that a rolled piece is stably deformed in a pass and obtaining a required geometric shape and size; the rolled piece is smoothly led out from the pass, so that the roll is prevented from being wound; controlling or forcing the rolled piece to twist or bend and deform and move in a certain direction. The guide and guard device consists of a cross beam, a guide plate, a clamp plate, a guide plate box, a supporting plate, a torsion guide plate, a torsion roller, a surrounding disc, a guide pipe and other devices for inducing and clamping a rolled piece or generating set deformation and torsion on the rolled piece at a hole type. Whether the design and the use of the guide and guard device are reasonable directly influences the quality of rolled products and the production capacity of a rolling mill. Although the hole pattern is reasonably designed, if the guide and guard device is improperly designed or used, qualified finished products cannot be rolled out.
The guide is one of important devices in the rolling line equipment, and the guide seat is the device for installing the guide. The common guide seat is fixed on a base of a rolling mill body, when the guide seat is installed, a bolt penetrates through a fastening internal thread hole at the bottom of the guide seat, a triangular iron is arranged between the bottom of the guide seat and a rolling mill beam, the fastening bolt is rotated, the bolt props against the triangular iron, the triangular iron props against the rolling mill beam, and the guide seat is firmly fastened on the rolling mill beam under two forces of vertical downward force and horizontal rightward force. After the guide seat is fastened, the adjusting screw rod which is arranged below the guide seat and used for transversely adjusting the position of the guide seat cannot rotate, so that the guide seat cannot transversely shift. However, in the steel rolling production process, due to the reasons of heavy production task, long service time, shaking of a rolling mill and the like, the thread slipping phenomenon often occurs in the threaded hole in the bottom of the guide seat, so that the guide seat is loosened, the guide moves, the guide position is not correct, and accidents such as steel running and the like are caused.
Aiming at the problem that the rolling accident is caused by the fact that the guide is shifted due to the fact that the thread of the internal thread hole at the bottom of the guide seat slides, the method for replacing the guide seat is basically adopted by domestic steel rolling mills at present. And the smooth silk phenomenon of the internal thread hole in the bottom of the guide seat often happens, the guide seat needs to be frequently replaced, and the guide seat is connected with the rolling mill body, so that the replacement is very troublesome, the guide seat is integrally disassembled and replaced and installed, the operation difficulty is greatly increased, the time and the labor are consumed, and the operation efficiency of the rolling line equipment of a steel mill is greatly influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a rolling mill guide seat convenient to maintenance is provided.
The utility model provides a technical scheme that its technical problem adopted is: the rolling mill guide seat comprises a guide seat body and further comprises a threaded sleeve, a positioning hole with an axis vertical to the axis of the connecting hole is formed in the positioning portion of the guide seat body, the outer ring surface of the threaded sleeve is in clearance fit with the positioning hole, and a positioning flange of the threaded sleeve is located on one side, close to the connecting hole, of the positioning portion.
Furthermore, at least one plane along the axial direction of the positioning hole is arranged in the positioning hole, at least one plane along the axial direction of the threaded sleeve is arranged on the outer ring surface of the threaded sleeve, and the plane in the positioning hole is parallel to the plane on the threaded sleeve.
Further, a rubber layer is arranged in the positioning hole.
The utility model has the advantages that: the rolling mill guide seat comprises a guide seat body and further comprises a threaded sleeve, an axis-perpendicular positioning hole is formed in the positioning portion of the guide seat body, the axis is perpendicular to the positioning hole of the connecting hole, the outer ring surface of the threaded sleeve is in clearance fit with the positioning hole, the positioning flange of the threaded sleeve is positioned on one side, close to the connecting hole, of the positioning portion, the connecting hole is used for connecting the guide seat body with the rolling mill body, the threaded sleeve is in clearance fit with the positioning hole and is screwed in the threaded sleeve and tightly supports a triangular iron, after threads in the threaded sleeve slide wires, only the threaded sleeve in the positioning hole needs to be replaced, the whole guide seat body does not need to be replaced, and maintenance is more convenient.
