Description
Technical field
The utility model belongs to mechanical equipment technical field, especially relates to a kind of roller holder formula workpiece hydraulic overturn system.
Background technology
At the heat treatment step of cold-strip steel roll bending, often need coil of strip be carried out the conversion of vertical position and horizontal position, the weight of every coil of strip ton does not wait from hundreds of kilogram to tens, needs the use tipper.For adapting to double, roll-over table has two mutually perpendicular work tops, and one side is a flat surface, and another side is the V-arrangement table top.During work, the place's planar end surface or the disc of coil of strip is placed on one of them work top, during lifting; The coil of strip side is difficult near the workbench facade, therefore, and in the switching process of 90 degree; Along with the rotation of center of gravity, workpiece slides and is seated on another table top, and impact is arranged in this process sometimes.
Existing tipper is different by the kind of drive, mainly is divided into two kinds of patterns, and a kind of is chain transmission tipper, and another kind is the hydraulic drive tipper.
Existing chain transmission tipper is made up of chain type roll-over table, chain-drive mechanism, carrying roller, base, electric appliance control box, travel control device.The advantage 1 of this pattern: the weight of workpiece and chain type roll-over table is born by the carrying roller that is fixed on the base; During work; Power only need overcome the turning torque that is produced because of the center of gravity of workpiece and chain type roll-over table and pivot decentraction; And the weight of workpiece and chain type roll-over table and the frictional force between the carrying roller, so required drive is less.Advantage 2: impact is arranged in work piece hoisting or the switching process sometimes, and carrying roller can bear the shock component of vertical direction.The shortcoming of this pattern is: because of chain transmission middle sprocket and chain have fit clearance, especially large-sized gap is bigger, job insecurity, and sprocket wheel has sliding tooth phenomenon sometimes during heavy duty, so the large-tonnage tipper does not generally adopt the chain transmission.Existing hydraulic drive tipper is made up of fluid pressure type roll-over table, Hydraulic Power Transmission System, bearing block, base, electric appliance control box, travel control device.
Existing fluid pressure type roll-over table has a main shaft, and passing the bearing block, the roll-over table that are fixed on the base is the center swing with the main shaft.The advantage of hydraulic drive tipper is: transmission stable working, system realize cushioning shock-absorbing easily, and can prevent overload automatically; Movement parts inertia is little, can commutate rapidly; Can realize infinitely variable speeds, speed adjustable range is big.Shortcoming is: power must overcome because of the center of gravity of workpiece and chain type roll-over table more much bigger with turning torque, this turning torque that rotating shaft center decentraction is produced than above-mentioned chaindriven turning torque; Impact in work piece hoisting or the switching process can be directly passed to oil cylinder; So existing large-tonnage hydraulic drive tipper need dispose the oil cylinder in the big footpath of two groups, supporting power of motor is also big.
For this reason, people have carried out long-term exploration, have proposed various solutions.For example, the Chinese patent document discloses a kind of turning device [application number: 200710049782.8] of large-scale component, and it is made up of at least 2 covers switching mechanism side by side; Switching mechanism comprises L type load-bearing revolving body, and the load-bearing revolving body has galianconism, long-armed, the long-armed revolution hinge that is provided with; The load-bearing revolving body is hinged with fixed hinged seat through the revolution hinge; Long-armed also hinged with the piston rod of hoist cylinder, the other end of hoist cylinder and hydraulic pressure free bearing are hinged, and hoist cylinder is connected with hydraulic control device through pipeline.Such scheme has improved job stability to a certain extent, is convenient to the upset of large-scale component.Technical problems such as but it is not high still to exist mechanical strength, and it is convenient inadequately to manipulate, and transmission is stable inadequately.
Summary of the invention

Therefore; The utility model is when work; Power only need overcome because of the turning torque that the center of gravity of workpiece and roll-over table and pivot decentraction are produced (this decentraction is apart from setting lessly during design); And the weight of workpiece and roll-over table and the frictional force between the carrying roller, so required drive is less.
In above-mentioned roller holder formula workpiece hydraulic overturn system, described hydraulic drive mechanism comprises pumping plant, is being connected with the oil cylinder that is fixed on the base on the pumping plant, and the piston rod of described oil cylinder and raceway plate are hinged.
In above-mentioned roller holder formula workpiece hydraulic overturn system, the both sides of described roll-over table are respectively equipped with the upset range controlling mechanism.
In above-mentioned roller holder formula workpiece hydraulic overturn system, described upset range controlling mechanism comprises supplemental support and the limited post that is fixed on the base, and the top of described supplemental support and limited post is provided with flexible cushion block.
In above-mentioned roller holder formula workpiece hydraulic overturn system; Described roll-over table also comprises two opposed V-arrangement connecting plates; Described raceway plate, first workbench and second stationary table are on the V-arrangement connecting plate; Form the space that supplies the piston rod swing between pivot pin and the two V-arrangement connecting plates being fixed with between two V-arrangement connecting plates, described piston rod is hinged on the pivot pin.
In above-mentioned roller holder formula workpiece hydraulic overturn system, also be provided with some connecting plates that are arranged in parallel between described two V-arrangement connecting plates.
