Summary of the invention
The objective of the invention is to change traditional processing mode that utilizes die forming sheet material, a kind of equipment for flexible rolled plate in 3 D curved surface based on the forming technique that has drive formula roller of realizing automatically control is provided.
Above-mentioned purpose of the present invention is achieved in that accompanying drawings is as follows.
A kind of equipment for flexible rolled plate in 3 D curved surface that has drive formula roller, it is made up of working roll, guiding mechanism and frame, described working roll is separate by some joints, the sub-roller of adjustable axle line position, the axis angle that can freely swing with the variation of workpiece cross curvature is formed, but described sub-roller is made the drive roll of active rotation, or the driven voller of passive rotation, or have the brake roller of arrestment mechanism, or by above-mentioned drive roll, driven voller, brake roller combination.
This device can be made up of at least two working rolls, guiding mechanism and frame, and each working roll is made up of a plurality of sub-rollers, and sub-roller is adjusted its position by guiding mechanism, constitutes the bending of work roll axis, and can rotate around jointed shaft, and can locate at an arbitrary position.
Said sub-roller Facing material can be steel, or other metal material, and sub-roller surface can have the polyurethane rubber cover.Sub-roller divides initiatively sub-roller again, by the mover roller with brake sub-roller.Initiatively but sub-roller self active rotation can be driven plate by between the working roll by it; Can not active rotation by mover roller self, the moving rotation of backup plate strip; Brake sub-roller and when not braking, move rotation, when on-position, play the effect that plate is increased tension force, help sheet forming as driven roll backup plate strip.
The equipment for flexible rolled plate in 3 D curved surface that has drive formula roller is to adopt several (at least two) working rolls by certain regularly arranged equipment that is used for the sheet material plastic working.Each working roll is made of several sub-rollers, and sub-roller produces displacement under the guiding mechanism effect, and sub-roller can turn an angle around jointed shaft; Change or the moving or rotate and make the plate different curvature that longitudinally is shaped of working roll neutron roller by the relative position of working roll, and along horizontal shaping different curvature.The relative position of working roll changes and the devices such as can passing through machinery, hydraulic-driven that moves of sub-roller is realized.The equipment for flexible rolled plate in 3 D curved surface that has drive formula roller can replace the flexible forming that traditional die forming is realized plate accessory.
The equipment for flexible rolled plate in 3 D curved surface that has drive formula roller has been used for reference the flexible variable thought of multi-point forming technique, the working roll of traditional venner reeling device or plate leveling apparatus is separated into a plurality of sub-rollers, make sub-roller axial arranged, and adjust along certain direction along working roll.Sub-roller adjustment can be manually (mixing up before the shaping, constant in the forming process) or by computer controlled automatic (mover roller in the forming process), sub-roller displacement determines according to the shape of three-dimension curved surface spare.This forming mode can be realized the progressive forming of sheet material three-dimension curved surface; Compare with traditional integral die forming mode, need not design, make, debug mould, save great amount of manpower and material resources and time.
