Abstract
The utility model discloses a movable partition piece with a steel longitudinal shearing unit. The movable partition piece comprises a piece body. The thickness a of the piece body is 6 mm, the small outer diameter c of the piece body is 160 mm, the large outer diameter d of the piece body is 250 mm, and the inner diameter b of the piece body does not change. The defect that steel belt edges formed after plate rolling and shearing are scratched and broken when rubbing the side face of the partition piece in the production and running process is overcome after the partition piece is used. The probability that the steel belt edges are scratched is lowered by more than 10%. By means of the newly-designed partition piece, the quality of sheared steel belts is improved, work efficiency is improved, and labor intensity is lowered. After the newly-designed partition piece is used, the friction faces of the sheared steel belts and the side face of the partition piece are narrowed, longitudinal shearing noise is reduced by 10%, and favorable conditions are created for safety production.
Description
Technical field
The utility model relates to the movable shim of a kind of band steel slitting line.
Background technology
The main material with Cr12MoV of the movable shim of slitting line, this material flexibility is good, and wearability, heat-resisting quantity are poor.In slitting line extensive use.The movable shim effect of slitting line is mainly: after circle shear is sheared when take-up, movable shim is pressed in steel coil strip roll bending, and many steel bands after shearing are spaced from each other, and makes steel band fitly be wound around rolling.The technological process that slitting line is produced is as follows: material loading → circle shear → fixing cutting plate device → jockey pulley → movable cutting plate device → curling → unload volume.The material C r12MoV that original movable shim uses, roll bending through circle shear shear after when take-up, movable shim is pressed in steel coil strip, many steel bands after shearing are spaced from each other, after in production run process, shim side easily rubs with steel band edge, make shim side easily be spread to cut by steel band edge and stay the integrated fritter in side of shim, cause steel band edge to produce cut, thereby reduce steel band quality, and also large (100--120 decibel left and right) of the noise of steel band edge and shim side friction production.Secondly, shim side and steel band contact-making surface are larger, steel band edge and shim side friction and cause shim hardness to change, the service life of reduction shim, thereby reduction steel band quality.
Summary of the invention
The purpose of this utility model is to provide a kind of band steel slitting line movable shim, can eliminate friction scratch defect, improves strip quality.
The purpose of this utility model is achieved in that the movable shim of a kind of band steel slitting line, comprises lamellar body, and the thickness a of lamellar body is 6mm, and little outside dimension c is 160mm, and large outside dimension d is 250mm, and internal diameter size b is constant.
The scratch of the newly-designed shim of the utility model has been avoided steel band edge after roll bending is sheared and shim side after using in the time that production run rubs, defect ruptures.Having improved steel band edge scratches more than 10%.Newly-designed shim carries after using that rear steel band quality is cut in cutting, operating efficiency has reduced labour intensity.Newly-designed shim reduces the steel band of shearing and the rubbing surface of shim side after using, reduce slitting noise 10% and also make safety in production create advantage.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is that master of the present utility model looks cross-sectional view.
The specific embodiment
The movable shim of a kind of band steel slitting line, as shown in Figure 1, comprises lamellar body, and the thickness a of lamellar body is 6mm, and little outside dimension c is 160mm, and large outside dimension d is 250mm, and internal diameter size b is constant.The utility model avoid roll bending through circle shear shear after when take-up, movable shim is pressed in steel coil strip, many steel bands after shearing are spaced from each other, in production run process, reduce after shim side easily rubs with steel band edge, make shim side easily be spread to cut by steel band edge and stay the integrated fritter in side of shim, cause steel band edge to produce cut, thereby improve steel band quality, secondly, reduce shim side and steel band contact-making surface, avoid steel band edge and shim side friction and cause shim hardness to change, extend the service life of shim, thereby improve steel band quality.
