Description
Technical field:
The utility model relates to the sheet metal technical field of processing equipment, especially relates to the apparatus for leveling in the plate-straightening machine.
Background technology:
Material sheet material in heating, rolling, finishing, transportation and various process because the external force effect, factor affecting such as variations in temperature and internal force growth and decline, often produce plastic deformation or internal residual stress such as in various degree bending, shape wave, sickle be curved or twisted, for eliminating these shape defects and residual stress to obtain straight finished steel, sheet material need be aligned leveling on straightener, and apparatus for leveling is the core apparatus of straightener, and it is widely used in process industries such as automobile, boats and ships, electronics.
Parallel rollers straightener in the sheet metal process equipment often needs high-speed cruising and reaches good leveling effect, and the apparatus for leveling of straightener can have influence on leveling effect because of the size and the layout situation of working roll footpath and roll spacing in running.The big corresponding requirements roll spacing in working roll footpath is big, and the excessive words of roll spacing make and sheet material plastic deformation deficiency do not guarantee flattening precision, and the while plate may skid, and can't nip; Working roll footpath is little, undercapacity then, and a little less than the rigidity, the easy starting the arc of working roll, leveling effect is not good.Therefore, how working roll is supported when optimizing the little working roll of utilization footpath, the combination property that improves apparatus for leveling becomes the pressing issues of pendulum in face of metal-working plant produces producer.
Relevant both at home and abroad pony roll footpath parallel rollers aligning apparatus for leveling, very little with the ratio of barrel length because of the roller footpath, working roll body of roll bending strength and rigidity are all very low, so except that adopting closed frame, great majority also are provided with backing roll and bear bending of work roll.Common pony roll footpath parallel rollers aligning apparatus for leveling, be provided with the single hop backing roll in the middle of its upper working rolls and lower working rolls, can the roll surface at middle part about 1/4th of work roll surface be supported, with flatness defect in the middle of eliminating, but it can't eliminate both sides or flatness defect on one side, and working roll and backing roll segmentation supporting, unbalance stress causes the mutual damage between two roll materials easily.Also has a kind of high-grade pony roll footpath parallel rollers aligning apparatus for leveling, the roller number of this apparatus for leveling is many, bulky, it is many to take up room, its upper working rolls and lower working rolls relevant position is equipped with three sections backing rolls, each section backing roll can be adjusted separately and depress, and can make sheet material produce different distortion along the working roll length direction, to eliminate both sides or middle or flatness defect on one side.But this kind apparatus for leveling is because of making and the installation error factors, and the location of backing roll and control are unstable, and it is big to adjust difficulty, working roll and backing roll segmentation supporting, and unbalance stress causes the mutual damage between two roll materials easily, and integral body is safeguarded very inconvenience.
Summary of the invention:
The purpose of this utility model is the weak point that exists at prior art and a kind of apparatus for leveling of new plate-straightening machine is provided, and it has simple and practical, and it is little to take up room, safeguard simple and easy, operation control is stable, the efficient height, and do not scratch advantage such as material surface.
For achieving the above object, the utility model includes top backing up roll group, lower support roller group, top working roll group, bottom working roll group, goes up linkage gear group, following linkage gear group, and top backing up roll group and lower support roller group drive top working roll group and bottom working roll group by last linkage gear group and following linkage gear group respectively; Top working roll in top backing up roll in the top backing up roll group and the top working roll group, and the lower support roller in the lower support roller group is that full roll surface contacts with bottom working roll in the bottom working roll group, its center line staggers mutually.
Top working roll in the above-mentioned top working roll group and the bottom working roll in the bottom working roll group respectively with the axle sleeve matched in clearance at its two ends, in addition, one end of top working roll and bottom working roll is provided with elastic tension apparatus so that top working roll and bottom working roll respectively with the top backing up roll group in top backing up roll keep well contacting with lower support roller in the lower support roller group.
Described elastic tension apparatus mount pad, pull bar, spring and fixed head constitute, and wherein, mount pad cooperates with the axle journal in the top working roll and the bottom working roll outside, and the pull bar lower end links to each other with mount pad, and the upper end cooperates with the spring that is positioned at fixed head.
Described upward linkage gear group is made of the intermeshing plug-in gear of top backing up roll and top working roll outer end, and following linkage gear group then is made of the intermeshing plug-in gear of lower support roller and bottom working roll outer end.
Top backing up roll in the described top backing up roll group is positioned in the memorial archway of the left and right sides, and top working roll then is positioned in the axis hole position between left and right sides memorial archway and the curved cover plate; Lower support roller in the lower support roller group is positioned at down in the memorial archway of the left and right sides, and bottom working roll then is positioned at down in the axis hole position between left and right sides memorial archway and the curved cover plate.
The plug-in gear back of described bottom working roll also is provided with the supporting structure that is made of secondary memorial archway and bearing.
The beneficial effects of the utility model are: its employing backing roll and the structure that the full roll surface of working roll contacts and center line staggers mutually, its backing roll can bear the bending of the vertical direction and the horizontal direction of working roll well, the strength and stiffness of working roll all obtain fabulous reinforcement during aligning, the roll spacing layout that also is optimized, simple and practical, take up room little, safeguard simple and easy, operation control is stable, efficient is high, use cost is low; In addition, the utility model has overcome the not good two kinds of defectives of leveling degree in the not enough and big working roll of the rigidity footpath in little working roll footpath, and the leveling effect significantly improves; The supporting of full roll surface simultaneously helps structure can not cause twice damage indirectly of material, and stressed evenly the supporting of other form is helped relatively, and the surface of material is played a very good protection.
