Abstract
The invention discloses a position guide of a rolling mill, which comprises a mounting seat, wherein a channel for a rolled piece to pass through is arranged in the mounting seat, chain belt conveying mechanisms are respectively arranged in grooves on the left side wall and the right side wall of the channel, and one side belt surface of a chain belt in the chain belt conveying mechanism is exposed into a rectangular channel and is tightly attached to the corresponding side of the rolled piece. The invention has good guiding function in the process of conveying rolled pieces and can ensure that the conveying path of the rolled pieces strictly enters and exits the guide channel in a straight line.
Description
Technical Field
The invention relates to the field of a screw-thread steel rolling mill, in particular to a guide device of a rolling mill.
Background
The guides are components which are customary in rolling mills and are used for introducing strip-shaped rolling stock between the roll pairs, the guide function being achieved by the guides. The existing position guide device is internally provided with a rectangular channel for a rolled piece to pass through, the left side and the right side of the rectangular channel are respectively rotatably provided with a position guide wheel, the position guide wheels are clamped on the left side and the right side of the rolled piece, and when a motor drives the position guide wheels to rotate, the rim of each position guide wheel is contacted with the corresponding side of the rolled piece to realize the transmission of the rolled piece. In order to ensure that the rolled piece passes through smoothly, the rectangular channel and the strip-shaped rolled piece are not in close fit. Because the rim of the guide wheel is in point contact with the corresponding side point of the rolled piece, and the rectangular channel is not tightly matched with the rolled piece, the rolled piece is easy to have the problem of deviation in the transmission process, so that the rolled piece cannot be strictly conveyed into the roller pair in the direction perpendicular to the straight line between the two rollers in the roller pair.
The invention aims to provide a guide of a rolling mill, which aims to solve the problem that the rolling mill fed by the guide for the rolling mill in the prior art has deviation.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
the utility model provides a position guide of rolling mill, includes the mount pad, has the rectangle passageway that supplies the rolled piece to pass through in the mount pad, its characterized in that: grooves are respectively formed in the left side wall and the right side wall of the rectangular channel, a chain belt conveying mechanism is respectively installed in the grooves, and a side belt face of a chain belt in the chain belt conveying mechanism is exposed out of the grooves to the rectangular channel and clings to the corresponding side of a rolled piece.
The position guider of the rolling mill is characterized in that: chain belt conveying mechanism installs in the recess and four axial vertical sprocket including rotating respectively, four sprockets distribute according to the rectangle, the rectangle has two sides to be on a parallel with the rolled piece business turn over direction, the chain belt suit is on each sprocket, and the chain belt distributes its tape surface along with the sprocket and is the rectangle, rectangle one side of chain belt tape surface is exposed to the rectangle passageway in and hugs closely the rolled piece from the recess and corresponds the side, the motor is installed to corresponding one or more sprocket position in mount pad top or bottom, the motor output shaft penetrates in the recess respectively and fixed connection corresponds the sprocket center.
The position guider of the rolling mill is characterized in that: among four chain wheels which are distributed in a rectangular mode in each groove, two chain wheels close to the channel are installed on a movable wheel carrier, two chain wheels far away from the channel are installed on a fixed wheel carrier, a hydraulic cylinder is fixed on the side wall of the installation seat corresponding to each groove, and a piston rod of the hydraulic cylinder extends into the groove along the direction perpendicular to the in-out direction of the rolled piece and then is fixed on the movable wheel carrier after penetrating through the fixed wheel carrier.
The position guider of the rolling mill is characterized in that: the grooves on the left and right side walls of the rectangular channel are mutually symmetrical or staggered in the in-out direction of the rolled piece.
According to the invention, the original guide wheel is replaced by the chain belt conveying mechanism, surface contact is realized by contacting one side belt surface of the chain belt with the corresponding side of the rolled piece so as to replace point contact of the guide wheel, the movable wheel carrier is driven by the hydraulic cylinder to move so as to ensure that one side belt surface of the chain belt is tightly attached to the corresponding side of the rolled piece, and then the rolled piece is conveyed by utilizing the movement of the chain belt. The chain belt is in surface contact with the rolled piece, so that the chain belt has a good guiding effect in the process of conveying the rolled piece, and the rolled piece can be ensured to strictly enter and exit the guide channel in a straight line along the conveying path of the rolled piece.
