Abstract
The short-stroke hydraulic downender for converting the vertical strip coil into horizontal strip coil includes one L-shaped tilting frame, one tilting hydraulic cylinder, one support base, one elevating bracket, and one elevating hydraulic cylinder. It features that one triangular turret as one isosceles triangle rigid body has the bottom hinged through one second hinging axle with the L-shaped tilting frame, the apex angle hinged through one third hinging axle with the turret seat, and upper surface comprising one bevel and one plane. The present invention has the features of short hydraulic cylinder stroke and small oscillation angle.
Description
Technical field
The present invention relates to a kind of down-ender that coil of strip is become horizontal roll by upright volume.
Technical background
Down-ender is the important accessory equipment in strip workshop.It drives and adopts hydraulic actuating cylinder mostly.The feeding system (crane or chain conveyor etc.) that the band steel is handled unit usually needs coil of strip is become horizontal roll by upright volume, is transported on the equipment of requirement by stepping equipment or other chain type transportation device again.As shown in Figure 1, traditional single fulcrum down-ender mainly is made up of activity material feeding platform, L type resupination framework 1, turnup hydraulic actuating cylinder 2, frame supporter 3, damping block 4, supporting seat 5, shears 6, lifting hydraulic cylinder 7 etc.L type resupination framework 1 a wherein arm is provided with shears 6 (or claim slipper bracket, also be movable Saddle with steel roll) and carries out the coil of strip height neutralization is rolled up; Carriage can slide on slideway, and is driven by lifting hydraulic cylinder 7.When L type resupination framework was accepted coil of strip (upright volume), lifting hydraulic cylinder 7 promotes shears 6 to carry out beginning to connect coil of strip after the height centering; Then, turnup hydraulic actuating cylinder 2 promotion L type resupination frameworks 1 revolve to turn 90 degrees and become the level position, and coil of strip has become horizontal roll by upright volume.Lifting hydraulic cylinder 7 is adjusted once more and is waited for behind the position that shears 6 arrive to require coil of strip and unload volume.
Traditional down-ender tilting equipment pattern generally adopts single fixed pivot, is rotated around this fixed pivot by turnup cylinder pushes L type resupination framework to reach the turnup purpose.Thisly there is following major defect around single fixed pivot turnup pattern:
With 30t coil of strip down-ender is example, sees Fig. 1,
1. the piston stroke of turnup hydraulic actuating cylinder 2 is oversize, and its hydraulic cylinder piston stroke requires 3080mm, and liquid cylinder entity length reaches 4060mm;
2. the pivot angle of turnup hydraulic actuating cylinder 2 is big.It is little that L type resupination framework hydraulic actuating cylinder and pivot clip in turning course are contended gradual change, turnup 90 degree, and the pivot angle of turnup hydraulic actuating cylinder 2 reaches 22.3 degree, and oil pressure changes greatly;
3. the foundation of civil work work capacity is big.Down-ender generally is placed on below ground, because that the oversize foundation of civil work of turnup hydraulic actuating cylinder 2 will dig 5000mm is how dark.
Summary of the invention
The object of the present invention is to provide the short-stroke hydraulic down-ender that a kind of turnup hydraulic cylinder piston stroke is short, pivot angle is little.
To achieve these goals, technical scheme of the present invention is: short-stroke hydraulic down-ender, it comprises L type resupination framework 1, turnup hydraulic actuating cylinder 2, supporting seat 5, shears 6, lifting hydraulic cylinder 7, the afterbody of turnup hydraulic actuating cylinder 2 and turnup hydraulic actuating cylinder bearing 14 are hinged, the piston rod attachment of turnup hydraulic actuating cylinder 2 is hinged with the horizontal arm of L type resupination framework 1 by first hinge 10, the upright arm of L type resupination framework 1 is provided with slideway, the slide block of shears 6 is positioned on the slideway, the piston rod attachment of lifting hydraulic cylinder 7 is connected with shears 6, and the middle part of lifting hydraulic cylinder 7 is articulated on the L type resupination framework 1; Supporting seat 5 is positioned at the right side of turnup hydraulic actuating cylinder 2; It is characterized in that: the horizontal arm of L type resupination framework 1 is hinged with the position, a base angle of triangle turret 9 by second hinge 11, triangle turret 9 is the rigid body of equicrural triangle, the angle position of triangle turret 9 is hinged with triangle turret bearing 13 by the 3rd hinge 12, and the 3rd hinge 12 is positioned on the drift angle bisector of triangle turret 9; The upper surface of triangle turret bearing 13 is made of inclined-plane and horizontal surface, and the inclined-plane is positioned at the left part, and the drift angle of triangle turret 9 is positioned at the inclined-plane and the horizontal surface intersection of triangle turret bearing 13.
The base angle of described triangle turret 9 is 45 °, and the inclined-plane of triangle turret bearing 13 and the angle between the horizontal surface are 135 °.
The inclined-plane and the horizontal surface of described triangle turret bearing 13 are provided with dash plate 8.
The invention has the beneficial effects as follows: utilized 2 fulcrum (O of conversion
3, O
2') structural principle, overcome shortcomings such as single fixed pivot turnup structural shape oil cylinder stroke is big, pivot angle is big, make that turnup hydraulic actuating cylinder pivot angle is very little, it is little that oil pressure changes, piston stroke significantly reduces, thereby reduces the foundation of civil work work capacity.From the turnup hydraulic actuating cylinder head movement figure (Fig. 1, Fig. 3) of two kinds of different structural shapes as can be seen, turnup hydraulic actuating cylinder head rise height of the present invention is more much smaller than single fulcrum, and this stability to turnup is very favourable.Triangle turret bearing of the present invention is simple in structure simultaneously, and processing and manufacturing is also very convenient.
