Abstract
The invention discloses a large-sized section numerical control stretch bending forming machine for a rail train, belonging to the technical field of non-ferrous metal processing and manufacturing. The large-sized section numerical control stretch bending forming machine is characterized in that two large arms are arranged on two sides of a worktable through four vertical shafts; one end of a rotating arm oil cylinder is connected with the large arms; the other end of the rotating arm oil cylinder is connected with the worktable; two screw rods are respectively arranged on the rear sides of the two large arms; sliding carriages are dragged by screw nuts on the left sliding plate and the right sliding plate to move on the large arms; vertical guide rails are arranged on the left sliding carriage and the right sliding carriage and are provided with an ascending sliding carriage and a descending sliding carriage; gimbals are embedded on the ascending sliding carriage and the descending sliding carriage; and a tension twisting oil cylinder can swing in the gimbals in a three-dimensional way. The invention has the benefits of no lubrication or less lubrication, simple structure, low cost, large bearing amount and reliable work. The invention ensures that the tensile deformation can be controlled; the structure is compact and stressed stably; by using the screw rods to move the sliding carriages and bear the stress to be positioned, the invention is convenient and flexible; and a pull head can be lifted so as to achieve the three-dimensional stretch.
Description
Technical field
The invention belongs to non-ferrous metal processing and manufacturing technical field.
Background technology
At present, in aluminium alloy processing enterprise, the pulling force of general stretch bending make-up machine is all at several tons to tens tons, and the large aluminum profile that when building high-speed track train or airliner, adopts, general stretch bending make-up machine pulling force is little, the large aluminum profile that at all can't stretch must be the large-scale stretch bending make-up machine more than 100 tons.
Summary of the invention
The objective of the invention is: a kind of track train large aluminum profile numerical control stretch bending make-up machine is provided, and it can draw large aluminum profile.
Technical scheme of the present invention is: the present invention is by compositions such as workbench, big arm, slide unit, mechanical skid plateform travel mechanism and hydraulic cylinder (big arm rotating cylinder, stretching cylinder, lift cylinders, compensating cylinder) Hydraulic Stations.
By four vertical shafts two big arms are installed in the workbench both sides, two big arms drive rotatable certain angle by two boom cylinders respectively.Boom cylinder one end links to each other with big arm, and end links to each other with workbench in addition, and effect is a bent section.
At two big arm rear sides two rhizoid thick sticks are installed respectively, under reducing motor drives, are rotated, by on big arm, moving, in order to adjust the needs of long and short section bar by drag slide carriage at screw on the left and right slide carriage.
Upright guide rail is housed on left and right slide carriage, on the upright guide rail ascending, descending slide carriage is arranged; Stud with gimbal on the ascending, descending slide carriage, draw and turn round can be in the gimbal three-dimensional swing of oil cylinder.Turn round oil cylinder and drag when moving up and down by drawing at the ascending, descending slide carriage, draw the high and low position of turning round oil cylinder in order to change.Draw and turn round oil cylinder and be in level or heeling condition by balancing cylinder control.
Section bar is packed on the mould of workbench, two ends be stuck in left and right draw turn one's head on, draw by two and to turn round oil cylinder and stretch, two big arms are swung under the oil cylinder effect backward, make section bar crooked on request, two variable speed electric motors, particularlies are controlled at section bar and finish section bar brake forming work on the correct direction.
Each bearing among the present invention is the steel backing composite bearing.
Sliding bearing among the present invention is the copper coin material, and sliding bearing is set on the steel pedestal.
The invention has the beneficial effects as follows: each bearing all adopts the steel backing composite bearing, can exempt from lubricated or few lubricating, and simple in structure, cost is low, and load-bearing is big, and reliable operation has overcome the overweight frangible problem of rolling bearing.All adopt hydraulic pressure, control each cylinder action characteristic, reach material and rationally be out of shape by position sensor.Make section bar stretcher strain controlled.Workbench is to bear mould to install, and is again big arm oil cylinder heavy frame.Compact conformation is stressed steadily.Take up an area of little, the simple material-saving in basis.Utilize leading screw to move slide carriage and bear pulling force and locate arbitrarily, convenient, flexible.Adopt all-hydraulicly, stretching cylinder band cylinder rod rotating hydraulic reducing motor can reverse section bar in drawing process.The pull head liftable reaches three-dimensional and stretches.
