Description
Technical field
The present invention relates to veneer reeling machine technical field, and in particular to roll two roller rolling machines of high rebound degree sheet material.
Background technology
As auto industry, aeronautical and space technology develop, industry, the demand of the product for civilian use, the utilization of new material is increasingly
Extensively, the especially titanium plate of high rebound degree, alloy sheets etc., its difficulty for rolling also further is lifted, and two roller rolling machines have
Roll workpiece product high precision, the characteristics of efficiency is fast, which is mainly made up of with lower resilient roller upper rigidity roller.One of them main spy
Levy is to roll workpiece product diameter by being molded rigidity roller（Also referred to as mould）Thickness determined that rigidity format roll is thicker, work
Part product diameter is bigger, and vice versa.Its proportionate relationship depends primarily on the rebound degree of sheet metal.
If when the sheet material for running into the larger characteristic of rebound degree rolls long cylinder, it is necessary to match relatively thin format roll,
But in the case where format roll is relatively thin, deflection deformation, or even bending, fracture can be produced after stress, and can not be made with rebound degree
The sheet material surrender of higher characteristic, it is impossible to rolled forming.
The content of the invention
The present invention is effectively solving high resilience plate roll bending this difficult problem, by the additional constraint on format roll into
Type roller arrangement compensates or even eliminates the adverse effect that deflection deformation is caused to increase rigidity, it is ensured that realize on two roller rolling machines
High resilience sheet material is rolled.
It is an object of the invention to provide additional constraint Forming Roller Device increases rigidity, compensation or even eliminates deflection deformation causing
Adverse effect, it is ensured that realizing rolling high resilience sheet material on two roller rolling machines.It is described to be molded firm roller arrangement 10
By the firm roller 1 of shaping, it is molded firm roller backbar 2, bearing block 3, is molded firm roller aiding support roller 4, nut-screw 5, backbar muscle
Plate 6 is constituted.
It is described to be molded firm roller arrangement（10）By the firm roller of shaping（1）, be molded firm roller backbar（2）, bearing block（3）, shaping it is firm
Roller aiding support roller（4）Nut-screw（5）Backbar gusset（6）Composition.
In order to solve the problems of background technology, the present invention is that format roll 1 is supported installed in " work " font format roll
Below beam 2, two ends are fixed by bearing block 3, can be used as driven roll forward and reverse." work " font format roll backbar 2, one end peace
It is mounted in frame 15, the other end is engaged with material returned overturning 7, after the completion of rolling workpiece 8, opens overturning 7, exit workpiece 8.
In 1 both sides of format roll, it is respectively symmetrically and some groups of constraint rollers 4 is installed.Constraint auxiliary wheel 4 is arranged on 2 gusset 6 of backbar
On, 6 Weld-supporting beam 2 of gusset.
Format roll backbar 2 of the present invention adopts I-shaped steel construction.Supporting force can be effectively improved, can be compressed
With reduce Forming Roller Device 10 space, so that the workpiece for barrel 8 for rolling can bypass Forming Roller Device 10.
Described its effect of constraint auxiliary wheel 4 of the present invention mainly has at 2 points, and one is restriction molding roller 1, is prevented into
Type roller 1 produces horizontal cross deflection deformation in forward and reverse, and two positions that can be by adjusting nut screw rod 5 change about
Constraint auxiliary wheel 4 and 2 relative distance of format roll backbar, compensate whole device deflection deformation operationally and ensure format roll
1 keeps straight, or can as needed within the specific limits, finely tune in vertical direction.
The high abrasion of the employing of aiding support roller 4 of the present invention, the hardness spy little less than shaping steel rider, frictional resistance
Property material, prevent its contact with format roll 1 rolling when to format roll 1 produce damage.
Description of the drawings
Fig. 1 is 10 structure chart of Forming Roller Device.
Fig. 2 is the two roller rolling machine structure charts for rolling high rebound degree sheet material.
Fig. 3 is the firm roller aiding support roller devices structure chart of shaping.
Specific embodiment
Referring to Fig. 2, this specific embodiment is employed the following technical solutions：It is by being molded steel rider 1, format roll backbar 2, axle
Bearing 3, format roll constraint auxiliary wheel 4, nut-screw 5, the overturning 7, sheet material of the backbar gusset 6, material returned（Workpiece for barrel）8、
Resilient roller 9, Forming Roller Device 10, hoist cylinder 11, chassis 12, hydraulic system 13, electrical apparatus control system 14, frame 15 are constituted.
Format roll 1 is arranged on below " work " font format roll backbar 2, and two ends are fixed by bearing block 3, can be used as driven roll
Forward and reverse.Format roll backbar 2 adopts I-shaped steel construction.Supporting force can be effectively improved, can be compressed and be dwindled into
The space of type roller arrangement 10, so that the workpiece for barrel 8 for rolling can bypass Forming Roller Device 10.
" work " font format roll backbar 2, one end are arranged in frame 15, and the other end is engaged with material returned overturning 7, is rolled up
After the completion of workpiece processed 8, overturning 7 is opened, workpiece 8 is exited.
In 1 both sides of format roll, it is respectively symmetrically and some groups of constraint rollers 4 is installed, its effect mainly has at 2 points, one is constraint
Format roll 1, prevents format roll 1 from producing horizontal cross deflection deformation in forward and reverse, and two can be by adjusting nut spiral shell
The position of bar 5 changes constraint auxiliary wheel 4 and 2 relative distance of format roll backbar, compensates whole device scratching operationally
Bent deformation ensures that format roll 1 keeps straight, or can as needed within the specific limits, finely tune in vertical direction.
Constraint auxiliary wheel 4 is arranged on 2 gusset 6 of backbar, 6 Weld-supporting beam 2 of gusset.Aiding support roller 4 is adopted
High abrasion, the hardness characteristic material little less than shaping steel rider, frictional resistance, prevent its contact with format roll 1 when rolling to into
Type roller 1 produces damage.
When high rebound characteristics sheet material 8, when being placed between format roll 1 and lower resilient roller 9, resilient roller 9 passes through hoist cylinder 11
Effect gradually rises, and sheet material 8 produces deformation under format roll 1 with lower 9 squeezing action of resilient roller.At the same time, resilient roller 9 is subtracting
Speed motor（Or hydraulic motor）It is rotated by, drives sheet material 8 to rotate with format roll 1, makes sheet material 8 obtain iso-curvature arc, plate
Material 8 progressively shapes workpiece for barrel 8, and the one end being shaped bypasses Forming Roller Device 10.
After it have matched thinner format roll 1, roll bending goes out required workpiece for barrel 8 to high resilience sheet material 8.
