Description
Technical Field
The invention relates to the field of metallurgy, in particular to a bending structure for improving the shearing tail of a multiple length flying shear.
Background
In the medium and small bar steel rolling continuous rolling production line, round steel produced by a whole blank needs to be segmented by a multiple-length flying shear, and then the round steel is controlled to be cooled by a cooling bed; when the multiple-length flying shears are segmented, the tail part of a small-size (less than or equal to phi 25mm) can impact the rear race groove bottom plate of the multiple-length flying shears due to the inertial force of the flying shears, and the rear race groove bottom plate of the flying shears needs to be in a horn-shaped opening for guiding, so that the tail part of a rolled piece impacts the bottom plate and then deforms and bends along the horn-shaped corner.
Disclosure of Invention
The purpose of the invention is as follows: in order to overcome the defects of the background art, the invention discloses a bending structure for shearing a tail part of a multiple-length flying shear, which solves the problem of tail part bending of multiple-length segments in the production process of medium and small rods and avoids the factors of yield loss, unstable production process and the like caused by overlong tail part bending.
The technical scheme is as follows: the improved bending structure for the shearing tail part of the double-length flying shear comprises a groove bottom plate which is horizontally arranged, wherein the groove bottom plate is connected through a plurality of groove supporting rollers, a rolled piece enters the groove bottom plate from the tail end of the groove bottom plate after being sheared by the flying shear to realize transmission, a movable turning plate is arranged at the tail end of the groove bottom plate, the movable turning plate is connected with the tail end of the groove bottom plate through a turning plate rotating shaft, and the tail end inclination angle of the groove bottom plate is adjusted through the turning plate rotating shaft.
Furthermore, a turning plate cylinder is arranged below the movable turning plate, the turning plate cylinder is fixed on the substrate of the whole device, and the telescopic end of the turning plate cylinder is connected with the bottom of the movable turning plate to drive the movable turning plate to adjust the angle.
Furthermore, a hot metal detector is arranged at the tail end of the running groove bottom plate and used for identifying the position of a rolled material; the hot metal detector is connected with the turnover plate cylinder to control the turnover plate cylinder to work.
When the rolled piece does not reach the flying shear position, the movable turning plate is at a low position to form a downward inclination angle, so that the rolled piece is conveniently guided into the running groove, and then the air cylinder drives the movable turning plate to return to a horizontal position; when the rolled piece is segmented by multiple lengths, the tail of the rolled piece still impacts the groove bottom plate, but at the moment, the groove movable turning plate is in a horizontal position, so that the rolled piece is not bent and deformed after impact.
Furthermore, the movable turning plate is of a flat plate structure, and when the rolled piece does not reach the multiple length flying shear, the movable turning plate is positioned at a low position to form a downward inclination angle; and after the head of the rolled piece passes through the movable turning plate, the movable turning plate is adjusted to a horizontal position.
Has the advantages that: compared with the prior art, the invention has the advantages that: this structure is according to the moving state that the rolled piece got into the race groove after the flying shear is cuted, will race the groove end and change into the adjustable structure of inclination for the rolled piece is under the prerequisite that gets into the race groove smoothly, and the afterbody can not produce curved steel, solves the curved steel problem of multiple length shearing afterbody.
Drawings
FIG. 1 is a schematic diagram of the present invention.
Detailed Description
The technical solution of the present invention is further described below with reference to the accompanying drawings and examples.
Improve multiple length flying shear shearing afterbody bending structure as shown in figure 1, race groove bottom plate 1 including the level setting, race groove bottom plate 1 is connected through a plurality of race groove bearing rollers 2, and the rolled piece is by race groove bottom plate 1 end entering race groove bottom plate 1 realization transmission after the flying shear shearing, the end of race groove bottom plate 1 is equipped with the activity and turns over board 3, the activity turns over board 3 through turning over board pivot 4 and race groove bottom plate 1 end-to-end connection, through turning over the board pivot 4 and adjusting the terminal inclination of race groove bottom plate 1.
A turning plate cylinder 5 is arranged below the movable turning plate 3, the turning plate cylinder 5 is fixed on a substrate 6 of the whole device, and the telescopic end of the turning plate cylinder is connected with the bottom of the movable turning plate 3 to drive the movable turning plate 3 to adjust the angle. The movable turning plate 3 is of a flat plate structure, and when a rolled piece does not reach the multiple length flying shear, the movable turning plate 3 is positioned at a low position to form a downward inclination angle; after the head of the rolled piece passes through the movable turning plate 3, the movable turning plate 3 is adjusted to the horizontal position. The tail end of the runner bottom plate 1 is provided with a hot metal detector for identifying the position of a rolled material; the hot metal detector is connected with the turnover plate cylinder 5 to control the turnover plate cylinder 5 to work.
Firstly, extending the lower bottom plate of the rear running groove of the multi-length flying shear in the direction close to the cutting edge of the flying shear, and reducing the distance between the superposed position of the cutting edge and the bottom plate 1 of the rear running groove as much as possible; secondly, the rear race groove bottom plate 1 of the multi-length flying shear is divided into two sections, one side far away from the cutting edge of the flying shear is designed as a fixed bottom plate, the position of the bottom plate 20-30cm close to the cutting edge of the flying shear is designed as a movable turning plate 3, and the movable turning plate 3 can rotate up and down through a turning plate rotating shaft 4 to change the inclination angle of the movable turning plate 3; and finally, a turning plate cylinder 5 is added below the movable turning plate 3 and used for automatically controlling the inclination angle of the turning plate in the production process, so that the adjustable bottom plate can be switched between a low position and a horizontal position. The hot metal detector detects the position of a rolled material in the production process, and when the rolled material does not reach the double-length flying shear, the movable turning plate is at a low position, namely, the movable turning plate is used as a bell mouth to guide a rolled piece; after the head of a rolled piece passes through the groove and before the multiple length subsection, the movable turning plate is adjusted to be in a horizontal position, at the moment, the tail part impacts the bottom plate after the multiple length subsection shearing, but because the movable turning plate is in the horizontal position, the tail part of the rolled piece cannot be bent, and therefore the problem of bending the tail part of the multiple length shearing is solved.
