Description
Technical Field
The invention relates to the field of deformed steel bar production devices, in particular to a guide device structure in a deformed steel bar roughing mill.
Background
A guide is a component which is customary in rolling mills and is used to introduce the rolling stock between a pair of rolls, the guide performing a guiding function by means of the guide. The device comprises a rough rolling mill, a position guide device, a position guide wheel and a position guide wheel, wherein the position guide device is arranged on the left side and the right side of the rectangular channel, the position guide wheel is driven by an external motor, and the position guide wheel is clamped on the left side and the right 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 is not tightly matched with the rolled piece. When a rolled piece enters the position guide from the guide position, the rolled piece is always in contact with the bottom of the rectangular channel inside the position guide, so that the problem of offset generally does not exist in the vertical direction, but the offset problem exists only by the aid of the position guide wheel to clamp the rolled piece in the horizontal direction. If the offset is large, the rolled piece conveyed into the roller pair through the position guide device cannot be strictly vertical to the position between the two rollers in the roller pair, and the structural performance of the rolled product can be influenced.
The invention aims to provide a position guide structure in a deformed steel bar roughing mill, which aims to solve the problem that the position guide in the roughing mill in the prior art does not have a deviation rectifying function.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
the utility model provides a position guide structure in screw-thread steel roughing mill, includes the mount pad, and the mount pad is inside to have the passageway that supplies the rectangle rolled piece to pass through, and left and right side rotates respectively in the passageway and installs the position guide wheel, and the inboard of position guide wheel stretches into respectively in the passageway and the centre gripping corresponds the side in the rolled piece, its characterized in that: a plurality of distance sensors are respectively installed on the left side wall and the right side wall of the channel close to the inlet, a sliding groove perpendicular to the in-and-out direction of a rolled piece is respectively arranged on the left side wall and the right side wall of the channel between the guide wheel and the outlet, a deviation rectifying seat is respectively installed in the sliding groove in a sliding mode, a linear stepping motor is respectively fixed on the left side wall and the right side wall of the installation seat corresponding to each sliding groove, and an output shaft of the linear stepping motor penetrates into the sliding groove and is fixedly connected with the deviation rectifying seat.
The position guider structure in the deformed steel bar roughing mill is characterized in that: and the left side wall and the right side wall of the channel are respectively provided with a mounting groove near the inlet, and the distance sensors are respectively mounted in the mounting grooves and arranged along the in-out direction of the rolled piece.
The position guider structure in the deformed steel bar roughing mill is characterized in that: the linear stepping motor is respectively provided with an encoder for detecting the rotation quantity of a rotating shaft in the motor, and the linear stepping motor further comprises a controller, wherein the input end of the controller is respectively connected with each distance sensor and the encoder, and the output end of the controller is connected with the motor controller of each linear stepping motor.
The position guider structure in the deformed steel bar roughing mill is characterized in that: the controller collects distance data measured by each distance sensor on the left side and the right side, and calculates the average value of the distance data measured on each side and the difference value of the average values on the left side and the right side; the controller is internally provided with a preset threshold value, the controller compares the difference value of the average values with the threshold value, and if the difference value is greater than the threshold value, the controller controls the left and right linear stepping motors to work through the motor controller, so that the left and right deviation rectifying bases respectively move in the same direction or in the opposite direction perpendicular to the in-and-out direction of the rolled piece, and the deviation rectification of the rolled piece is realized.
In the invention, the distance between the distance sensor and the left side and the right side of the rolled piece is acquired by the distance sensor at the entry section of the rolled piece and is sent to the controller to judge whether deviation exists in the left and right directions, if the deviation exists, the controller controls the output shaft of the linear stepping motor to move linearly for a corresponding distance, and the deviation correction is realized by the contact of the deviation correction seat and the rolled piece. If the left and right deviation rectifying seats always contact with the rolled piece, the left and right deviation rectifying seats move in the same direction perpendicular to the in-and-out direction of the rolled piece during deviation rectifying; if the deviation exists when only one side of the deviation rectifying seat is in contact with the rolled piece or the deviation rectifying seats on the two sides are not in contact with the rolled piece, the left deviation rectifying seat and the right deviation rectifying seat move reversely in the direction perpendicular to the in-and-out direction of the rolled piece during deviation rectifying.
Compared with the prior art, the invention can realize the correction of the posture of the rolled piece before the rolled piece is guided into the rollers, so as to ensure that the rolled piece is strictly vertical between the two rollers in the roller pair, and improve the rolling effect of the roughing mill.
