Abstract

Shell plates with curved surfaces are often used for forming various storage tanks and house roofs in petrochemical industry, metallurgy and building industry. The existing methods for processing shell plates with curved surfaces comprise a punching method, a rolling method and a spinning method. The punching method and the rolling method need large moulds, and the spinning method can only be used for processing shell plates with curved surfaces, which have sealed circumferential edges. The method of the present invention comprises: a plate material is cut into a plate blank in a certain shape, and the plate blank is driven to make a reciprocating movement. The continuous partial forming of the shell plates with curved surfaces can be realized in the process without large moulds. The method of the present invention not only can be used for processing shell plates with curved surfaces, which have complete circumferential edges, but also can be used for processing shell plates with curved surfaces, which have incomplete circumferential edges.

Description

The curved shell plate process equipment

The present invention relates to a kind of equipment that utilizes the continuous and local shaping Sheet Metal Processing to be become curved shell plate.

In petrochemical industry, metallurgy and building trade, curved shell plate is usually used in making various storage tanks, and as spherical storage tank, cylindrical oil tank, and building structure are as the roof, house.In addition, they also are used to make large-scale receiving paraboloid.The equipment that is used for the processing curve coverboard at present mainly contains three kinds, i.e. pressing equipment, roll unit and spinning machine.

Utilizing pressing equipment processing curve coverboard is that plate is placed on the mould, with the forcing press pressurization coverboard is shaped, and required pressure machine tonnage is big and mould is expensive.Large-scale storage tank generally is a single-piece, small lot batch manufacture, and this and forcing press mold processing plate are adapted to produce in enormous quantities and produce huge contradiction, and be consequently uneconomical economically.

Utilizing roll unit processing curve coverboard is that plate is passed through by several raceways to forming between spill roller and convex roller, and one stroke is finished the shaping of curved shell plate.When this equipment was used for the processing curve coverboard, the length of forming rolls needed the width greater than plate, and therefore the curved shell plate width of processing is subjected to the restriction of roller rigidity.The Breadth Maximum of roll extrusion at present is 2100 millimeters.Often there is local ripple at the edge of the curved shell plate behind the rolling forming, needs follow-up trimming to carry out shaping.Publish nineteen ninety referring to building industry publishing house, Wang Jialin edits " spherical storage tank building technology " P88～90.

No matter be pressing equipment or roll unit, when the processing curve coverboard, all have the expensive large mold (in roll unit, mould is made up of seaming roll) of needs, this with the many kinds of curved shell plate, the contradiction that the small lot batch manufacture generation is huge.

Spinning machine is a kind of continuous and local former, though do not need large mold, is only applicable to process the curved shell plate with closed circular perimeter.Published " rotary pressure technology " of work such as king Cheng He in 1986 referring to China Machine Press.

For a long time, people attempt to seek a kind of small lot that is applicable to always, and many kinds processing curve coverboard does not need large mold, and only needs inexpensive frock, widely applicable process equipment.

The objective of the invention is to overcome pressing equipment and roll unit processing curve coverboard needs large mold, do not fit into many kinds, the deficiency of small lot batch manufacture, spinning machine can only be processed the restriction of closed circular perimeter curved shell plate, a kind of specification and size when changing when curved shell plate is provided, only need to change the shaping that several very little parts just can be realized curved shell plate, the curved shell plate that is not only applicable to process the closed circular perimeter also is suitable for processing on-circular boundary surface coverboard, as the flexible machining equipment of strip curved shell plate.

Several the measures of narrating below all can realize purpose of the present invention.

straightway on the straight line of conical shell surfaces externally and internally bus place under the clamping device niproll, then slab is at clamping device, when reciprocatingly moving under the building mortion roller driven in synchronism, be subjected to part after each bending of building mortion is handled for can open up conical surface coverboard, if this track is a curve, then slab is at clamping device, and being subjected to the part after each bending of building mortion is handled in the process that reciprocatingly moves under the building mortion roller driven in synchronism is the curved shell plate that can not open up.If all parts or the clamping device of slab, the part that building mortion does not touch needs building mortion processing to handle the shape and size that just can be configured as requirement, then building mortion contact to slab partially-formed after, the position that the part that the position that changes slab makes needs processing places

revolution of the roller in the stream oriented device, direction, position and adjustment.The position of adjusting the clamping device roller makes it contact and apply power with slab, the zone that slab contacts with the clamping device roller applies under the moment of flexure effect that power forms at roller and produces the local buckling plastic deformation, during the reciprocal forward and reverse revolution of clamping device roller, clamp slab and drive slab and do stable reciprocating motion.After clamping device clamps slab, adjust the position of building mortion roller, make its roller apply power and clamp slab slab, spinning roller pushes slab to forming rolls, the pinching end of spinning roller, forming rolls, counter-pressure cylinder and clamping device

roller, the second limit roller and spinning roller, forming rolls cooperate and slab is applied moment of flexure make slab produce flexural deformation in another plane, thus the zone that slab contact with building mortion roller generation local buckling plastic deformation under the moment of flexure effect of the power formation that the building mortion roller applies slab.During the reciprocal forward and reverse revolution of building mortion roller, (can guarantee that slab is done stable reciprocating motion when building mortion is processed slab with the roller driven in synchronism of clamping device if the driving force of clamping device is enough big, only needing drive with clamping device) slab does stable the reciprocating motion, and the roller of building mortion is shifted to the outward flange of slab simultaneously.In this process, the relative position of adjusting each roller is with the needs of the variation that adapts to curved shell plate different parts curvature, the plastic zone of slab is enlarged, and up to spreading all over the slab part that successively contacts with the building mortion roller, this part of slab is processed to curved shell plate.If all parts or the clamping device of slab, the part that building mortion does not touch needs building mortion processing to handle the shape and size that just can be configured as requirement, then after the slab that building mortion can be worked into is partially-formed, the position that the part that the position that changes slab makes needs processing

this part.

D) plate that will have a plastic deformation ability cuts into the slab of definite shape, places the clamping device and the building mortion that are installed on the same fuselage then.Clamping device plays the clamping slab, drives the effect that slab moves reciprocatingly, and the retained part of clamping device is by two disk-like object of back and forth rotating around dead axle, and promptly two clamping disks are formed.Slab places upper and lower clamping disk to clamp.The effect of building mortion is to cooperate the driving slab to do stable the reciprocating motion with the clamping disk of clamping device, in the process of slab outward flange motion, slab is applied power at its roller and make slab produce the local buckling plastic deformation, by the forming rolls that is positioned at the slab top that can back and forth rotate, the spinning roller that is positioned at the slab below, the first limit roller, the second limit roller and the counter-pressure cylinder that are distributed in the slab part below of the both sides, plane that preceding two roll axis are determined form.Counter-pressure cylinder can be around self axis reciprocating rotating.Counter-pressure cylinder is positioned at the slab below, close spinning roller one side between the spinning roller of building mortion and the clamping device, so that when shaping device during away from the pinching end of clamping device niproll, counter-pressure cylinder, forming rolls and spinning roller cooperation apply moment of flexure to slab, make slab determine to produce in the plane local buckling at forming rolls and spinning roller axis.The relative position of the forming rolls of building mortion, spinning roller, the first limit roller and the second limit roller can be adjusted, spinning roller is relative with forming rolls and leave certain distance therebetween, the axis of rotation coplane of two niprolls of the axis of rotation of forming rolls and spinning roller and clamping device, the angle of forming rolls and spinning roller axis adjusts according to the needs that are shaped in sheet forming process, and machinery--electric, pneumatic or full hydraulic drive is adopted in the change of the revolution of the roller in the stream oriented device, direction, position and adjustment.Adjustment clamping device clamping disk makes it clamp slab and drives slab does reciprocal dead axle swing.Contact with slab after the adjustment of building mortion roller and slab is applied power, spinning roller pushes slab to forming rolls, spinning roller, forming rolls, the clamping disk cooperation of counter-pressure cylinder and clamping slab applies moment of flexure to slab, make the flexural deformation in slab generation forming rolls and the plane, spinning roller axis place, the axis of rotation coplane of two clamping disks of the axis of rotation of forming rolls and spinning roller and clamping device, the first limit roller, second limit roller and the forming rolls, the spinning roller cooperation applies moment of flexure to slab makes slab produce the local buckling distortion in another plane, thereby the part of slab in building mortion occurs bending and deformation, the clamping disk driven in synchronism slab of reciprocal forward and reverse when revolution of building mortion roller and clamping device is around the dead axle reciprocally swinging, or the building mortion roller drives slab separately and does dead axle swing, clamping disk only plays clamping action, the building mortion roller moves to the edge of slab simultaneously, the relative position of each roller of building mortion adjusts accordingly according to the needs of the variation of the different position curvature of curved shell plate, and the plastic zone constantly enlarges in this process.In the plane that axis of rotation determined of the axis of rotation of forming rolls, spinning roller and clamping disk, if each roller of building mortion contacts with slab, the track of contact point is a straight line on the slab, then slab is the circular cone coverboard that can open up after building mortion roller bending machining is handled, if track is a curve, then become the curved shell plate that to open up.

6) in the building mortion of present device, above the slab part of the both sides on forming rolls and spinning roller plane that axis determines, the 3rd limit roller and the 4th limit roller are set respectively, or below the slab part of the both sides on forming rolls and spinning roller plane that axis determines, set up the 5th limit roller and hexagon roller respectively, and be positioned at the outside of the first limit roller and the second limit roller, or both of these case occurs simultaneously in building mortion, to strengthen the local buckling effect that building mortion partly produces therebetween slab and to guarantee that the slab edge also can be configured as desired curved shell plate part.The situation that is provided with that will increase the limit roller in conjunction with each equipment is described below respectively:

A) plate that will have a plastic deformation ability cuts into the slab of definite shape, place then be installed on the same fuselage by roller or its analog that can rotate around self axis, maybe can be as single roller around reciprocating a plurality of rollers of same axis etc., in the clamping device and building mortion of composition.Clamping device plays clamping, drive the slab effect, and realize partially-formed function, by two niprolls that can reciprocating rotating, two limit rollers are formed, and the relative position of these niprolls and limit roller can be according to the clamping slab, the needs that drive slab adjust, it is parallel that two niproll axis can be adjusted to, and upper and lower two niproll clamping slabs, two limit rollers are distributed in the below of slab part of the both sides on two niproll planes that axis determines.Building mortion by the forming rolls that is positioned at the slab top that can reciprocating rotating, be positioned at the spinning roller of slab below and be distributed in forming rolls respectively and the slab of the both sides on spinning roller plane that axis determines part below the first limit roller and the second limit roller form, spinning roller is relative with forming rolls and leave certain distance therebetween, the axis of rotation coplane of two niprolls of the axis of rotation of forming rolls and spinning roller and clamping device, the relative position of roller can be adjusted.In building mortion, also above the slab part of the both sides on forming rolls and spinning roller plane that axis determines, the 3rd limit roller and the 4th limit roller are set respectively, or below the slab part of the both sides on forming rolls and spinning roller plane that axis determines, set up the 5th limit roller and hexagon roller respectively, and be positioned at the outside of the building mortion first limit roller and the second limit roller, or both of these case occurs simultaneously in building mortion, to strengthen the local buckling effect that building mortion partly produces therebetween slab and to guarantee that the slab edge also can be configured as desired curved shell plate part.Moving (change of direction and position) and adjusting employing of the revolution of the roller in the stream oriented device, roller gyroaxis is mechanical--electric, pneumatic or full hydraulic drive.The position of adjusting the clamping device roller makes it contact and apply power with slab, the zone that slab contacts with the clamping device roller applies under the moment of flexure effect that power forms at roller and produces the local buckling plastic deformation, during the reciprocal forward and reverse revolution of clamping device roller, clamp slab and drive slab and do stable reciprocating motion.After clamping device clamps slab, adjust the position of building mortion roller, make its roller apply power and clamp slab slab, spinning roller pushes slab to forming rolls.The pinching end cooperation of spinning roller, forming rolls and clamping device niproll applies moment of flexure to slab, thereby make slab generation forming rolls and spinning roller axis of rotation determine flexural deformation in the plane, building mortion limit roller and spinning roller, forming rolls cooperate and slab is applied moment of flexure make slab produce flexural deformation in another plane, thus the zone that slab contact with building mortion roller generation local buckling plastic deformation under the moment of flexure effect of the power formation that the building mortion roller applies slab.During the reciprocal forward and reverse revolution of building mortion roller, (can guarantee that slab is done stable reciprocating motion when building mortion is processed slab with the roller driven in synchronism of clamping device if the driving force of clamping device is enough big, only needing drive with clamping device) slab does stable the reciprocating motion, and the roller of building mortion is shifted to the outward flange of slab simultaneously.In this process, the relative position of adjusting each roller is with the needs of the variation that adapts to curved shell plate different parts curvature, and the plastic zone of slab is enlarged, and up to spreading all over the slab part that successively contacts with the building mortion roller, this part of slab is processed to curved shell plate.If all parts or the clamping device of slab, the part that building mortion does not touch needs building mortion processing to handle the shape and size that just can be configured as requirement, then after the slab that building mortion can be worked into is partially-formed, the position that the part that the position that changes slab makes needs processing places building mortion to be worked into, each roller of clamping device changes roller or remain unchanged (if clamping device part does not down need building mortion to process) that the curve form that obtains after profile and each roller of building mortion are handled plate bending matches into, each roll axis position of clamping device obtains adjusting and makes each roller will be subjected to retained part to contact and apply power with the curved shell plate that is shaped, roller driven in synchronism slab with building mortion moves reciprocatingly then, building mortion is processed the part of the processing of still needing, and finishing dealing with up to this part obtains desired curved shell plate.

B) plate that will have a plastic deformation ability cuts into the slab of definite shape, places the clamping device and the building mortion that are installed on the same fuselage then.Clamping device plays the clamping slab, drive the effect that slab moves reciprocatingly, by two cylindrical niprolls that can reciprocating rotating, two cylindrical limit rollers are formed, the relative position of these niprolls and limit roller can be according to the clamping slab, and the needs that drive slab adjust, and two niproll axis can be adjusted to parallel, upper and lower two niproll clamping slabs, two limit rollers are distributed in the slab below partly of the both sides on two niproll planes that axis determines.The both sides roll axis is adjusted to and is parallel to the plane that two niproll axis are determined.The effect of building mortion is to cooperate the driving slab to do stable the reciprocating motion with the roller of clamping device, in the process of slab outward flange motion slab being applied power at its roller makes slab produce the local buckling plastic deformation, by the forming rolls that is positioned at the slab top that can back and forth rotate, the first limit roller and the second limit roller that are positioned at the spinning roller of slab below and are distributed in the slab part below of the both sides, plane that preceding two roll axis are determined are formed, the forming rolls of building mortion, spinning roller, the relative position of the first limit roller and the second limit roller can be adjusted, spinning roller is relative with forming rolls and leave certain distance therebetween, the axis of rotation coplane of two niprolls of the axis of rotation of forming rolls and spinning roller and clamping device, the angle of forming rolls and spinning roller axis adjust according to the needs that are shaped in sheet forming process.In building mortion, also above the slab part of the both sides on forming rolls and spinning roller plane that axis determines, the 3rd limit roller and the 4th limit roller are set respectively, or below the slab part of the both sides on forming rolls and spinning roller plane that axis determines, set up the 5th limit roller and hexagon roller respectively, and be positioned at the outside of the building mortion first limit roller and the second limit roller, or both of these case occurs simultaneously in building mortion, to strengthen the local buckling effect that building mortion partly produces therebetween slab and to guarantee that the slab edge also can be configured as desired curved shell plate part.Machinery--electric, pneumatic or full hydraulic drive is adopted in the change of the revolution of the roller in the stream oriented device, direction, position and adjustment.In clamping device, adjusting each roller is parallel to each other its axis and contacts the power of applying with slab, make plate bending and local buckling distortion takes place, then slab moves reciprocatingly under clamping device drives in the process, is subjected to the cylinder shell of part for opening up after the bending process of clamping device roller.For building mortion, adjusting each roller position makes them contact with slab and the power that applies makes slab occur bending and deformation with the part that the building mortion roller contacts, be set as each roller of shape device and be parked in their arbitrary positions in slab edge moving process, when then slab moves reciprocatingly, contact point between roller and the slab will be described out track in the plane perpendicular to clamping device roll axis direction on slab, establish slab equally and be parked in arbitrary position in the reciprocating motion process, and each roller of shaping device moves to the slab edge, and the contact point between roller and the slab will be described out track in the plane that clamping device two niproll axis are determined on slab.If preceding a kind of track is a straightway, a kind of track in back is that curve or preceding a kind of track are that then a kind of track of curve is the straightway that is parallel to clamping device niproll axis, then slab moves reciprocatingly and is subjected to building mortion bending process rear portion to be divided into the cylinder coverboard that can open up, if preceding a kind of track is that then a kind of track of curve also is a curve, then slab is subjected to the curved shell plate of part for opening up after the bending process of building mortion roller.If all parts or the clamping device of slab, the part that building mortion does not touch needs building mortion processing to handle the shape and size that just can be configured as requirement, then after the slab that building mortion touches is partially-formed, the position that the part that the position that changes slab makes needs processing places building mortion to be worked into, the roller that the curve form that obtains after each roller of clamping device changes profile into and handles through each bending of building mortion matches or remain unchanged (if the part under the clamping device does not need building mortion processing), each roll axis position of clamping device obtains adjusting and makes each roller and the curved shell plate that is shaped will be subjected to the part of clamping to contact and apply power clamping slab, the roller driven in synchronism slab of each roller of clamping device and building mortion moves reciprocatingly then, the part that building mortion processing waits to process reaches requirement up to the shape and size of this part.

C) plate that will have a plastic deformation ability cuts into the slab of definite shape, places the clamping device and the building mortion that are installed on the same fuselage then.Clamping device plays the clamping slab, drives the effect that slab moves reciprocatingly, and by two niprolls that can reciprocating rotating, two limit rollers are formed.The relative position of these niprolls and limit roller can be according to the clamping slab, the needs that drive slab adjust, two niproll axis can be adjusted to parallel, upper and lower two niproll clamping slabs, two limit rollers are distributed in the slab below partly of the both sides on two niproll planes that axis determines.In clamping device, upper and lower two niprolls and both sides roller are respectively with two cover transmission device transmissions, upper and lower niproll drives big mouthful of slab, the osculum of the moving slab of limit roller strap, suitable speed governing by transmission device make big mouthful and osculum to move back and forth angular speed the same, make the slab part of each roller contact of clamping device after handling, become conical surface coverboard through each bending, each roller of clamping device clamps slab and drives slab and does reciprocal moving then, for guaranteeing that upper and lower niproll fully contacts with slab, the niproll profile also allows with certain tapering.The effect of building mortion is to cooperate the driving slab to do stable the reciprocating motion with the roller of clamping device, in the process of slab outward flange motion slab being applied power at its roller makes slab produce the local buckling plastic deformation, by the forming rolls that is positioned at the slab top that can back and forth rotate, the first limit roller and the second limit roller that are positioned at the spinning roller of slab below and are distributed in the slab part below of the both sides, plane that preceding two roll axis are determined are formed, the forming rolls of building mortion, spinning roller, the relative position of the first limit roller and the second limit roller can be adjusted, spinning roller is relative with forming rolls and leave certain distance therebetween, the axis of rotation coplane of two niprolls of the axis of rotation of forming rolls and spinning roller and clamping device, the angle of forming rolls and spinning roller axis adjust according to the needs that are shaped in sheet forming process.In building mortion, also above the slab part of the both sides on forming rolls and spinning roller plane that axis determines, the 3rd limit roller and the 4th limit roller are set respectively, or below the slab part of the both sides on forming rolls and spinning roller plane that axis determines, set up the 5th limit roller and hexagon roller respectively, and be positioned at the outside of the building mortion first limit roller and the second limit roller, or both of these case occurs simultaneously in building mortion, to strengthen the local buckling effect that building mortion partly produces therebetween slab and to guarantee that the slab edge also can be configured as desired curved shell plate part.Machinery--electric, pneumatic or full hydraulic drive is adopted in the change of the revolution of the roller in the stream oriented device, direction, position and adjustment.In building mortion, adjust each roller position and they are contacted and the power that applies makes the plastic deformation that bends of the part of slab under the building mortion roller with slab.When each roller turns round in the building mortion, do reciprocal moving with the roller driven in synchronism slab of clamping device.If slab is parked in the arbitrary position in the process of moving back and forth, at each roller of building mortion in slab edge moving process, contact point between forming rolls and spinning roller and the slab will the plane that clamping device two niproll axis are determined on slab in (forming rolls of building mortion and spinning roller axis are also in this plane) track is described out, if track is the straightway on the straight line of conical shell surfaces externally and internally bus place under the clamping device niproll, then slab is at clamping device, when reciprocatingly moving under the building mortion roller driven in synchronism, be subjected to part after each bending of building mortion is handled for can open up conical surface coverboard, if this track is a curve, then slab is at clamping device, and being subjected to the part after each bending of building mortion is handled in the process that reciprocatingly moves under the building mortion roller driven in synchronism is the curved shell plate that can not open up.If all parts or the clamping device of slab, the part that building mortion does not touch needs building mortion processing to handle the shape and size that just can be configured as requirement, then after the slab that building mortion touches is partially-formed, the position that the part that the position that changes slab makes needs processing places building mortion to be worked into, each roller of clamping device changes roller or remain unchanged (if clamping device part does not down need building mortion to process) that the curve form that obtains after profile and each roller of building mortion are handled plate bending matches into, each roll axis position of clamping device obtains adjusting and makes each roller contacted by retained part with the curved shell plate that is shaped and apply power clamping slab, roller driven in synchronism slab with building mortion moves reciprocatingly then, the part that building mortion processing waits to process reaches requirement up to the shape and size of this part.

7) plate that will have a plastic deformation ability cuts into the slab of definite shape, place then be installed on the same fuselage by roller or its analog that can rotate around self axis, maybe can be as single roller around reciprocating a plurality of rollers of same axis etc., in the clamping device and building mortion of composition.Clamping device plays the clamping slab, drives the effect that slab moves reciprocatingly, and by two niprolls that can reciprocating rotating, two limit rollers are formed.The relative position of these niprolls and limit roller can be according to the clamping slab, the needs that drive slab adjust, two niproll axis can be adjusted to parallel, upper and lower two niproll clamping slabs, two limit rollers are distributed in the slab below partly of the both sides on two niproll planes that axis determines.The both sides roll axis is adjusted to and is parallel to the plane that two niproll axis are determined.The effect of building mortion is to cooperate the driving slab to do stable the reciprocating motion with the roller of clamping device, in the process of slab outward flange motion, slab is applied power at its roller and

roller that are positioned at the spinning roller of slab below and are distributed in the slab part below of the both sides, plane that preceding two roll axis are determined.The lateral surface bus arc shape of the forming rolls of building mortion and curved shell plate upper surface determine the arc shape in the plane to match at forming rolls and spinning roller axis of rotation, for example, if the arc shape of upper surface in this plane of curved shell plate is the circular arc of a certain radius, then the lateral surface bus arc shape of forming rolls is got the circular arc of same radius, and the length that the length of bus arc allocates the camber line in the face more than or equal to the forming rolls and the spinning roller axis of curved shell plate upper surface

rotation does not move, and other roller is engaged in the shaping that realizes curved shell plate in the outer peripheral process of shifting to slab with forming rolls in slab reciprocating motion process.Machinery--electric, pneumatic or full hydraulic drive is adopted in the change of the revolution of the roller in the stream oriented device, direction, position and adjustment.The position of adjusting the clamping device roller makes it contact and apply power with slab, the zone that slab contacts with the clamping device roller applies under the moment of flexure effect that power forms at roller and produces the local buckling plastic deformation, during the reciprocal forward and reverse revolution of clamping device roller, clamp slab and drive slab and do stable reciprocating motion.After clamping device clamps slab, adjust the position of building mortion roller, make its roller apply power and clamp slab slab, spinning roller pushes slab to forming

reciprocating motion when building mortion is processed slab with the roller driven in synchronism of clamping device if the driving force of clamping device is enough big, only needing drive with clamping device) slab does stable the reciprocating motion, and the roller of building mortion is shifted to the outward flange of slab simultaneously.In this process, the relative position of adjusting each roller is with the needs of the variation that adapts to curved shell plate different parts curvature, and the plastic zone of slab is enlarged, and up to spreading all over the slab part that successively contacts with the building mortion roller, this part of slab is processed to curved shell plate.If all parts or the clamping device of slab, the part that building mortion does not touch needs building mortion processing to handle the shape and size that just can be configured as requirement, then after the slab that building mortion can be worked into is partially-formed, the position that the part that the position that changes slab makes needs processing places building mortion to be worked into, each roller of clamping device changes roller or remain unchanged (if clamping device part does not down need building mortion to process) that the curve form that obtains after profile and each roller of building mortion are handled plate bending matches into, each roll axis position of clamping device obtains adjusting and makes each roller will be subjected to retained part to contact and apply power with the curved shell plate that is shaped, roller driven in synchronism slab with building mortion moves reciprocatingly then, building mortion is processed the part of the processing of still needing, and finishing dealing with up to this part obtains desired curved shell plate.

the curved shell plate that is shaped, roller driven in synchronism slab with building mortion moves reciprocatingly then, building mortion is processed the part of the processing of still needing, and finishing dealing with up to this part obtains desired curved shell plate.

B) plate that will have a plastic deformation ability cuts into the slab of definite shape, places the clamping device and the building mortion that are installed on the same fuselage then.Clamping device plays the clamping slab, drives the effect that slab moves reciprocatingly, and by two cylindrical niprolls that can reciprocating rotating, two cylindrical limit rollers are formed.The

kind of track are that then a kind of track of curve is the straightway that is parallel to clamping device niproll axis, then slab moves reciprocatingly and is subjected to building mortion bending process rear portion to be divided into the cylinder coverboard that can open up, if preceding a kind of track is that then a kind of track of curve also is a curve, then slab is subjected to the curved shell plate of part for opening up after the bending process of building mortion roller.If all parts or the clamping device of slab, the part that building mortion does not touch needs building mortion processing to handle the shape and size that just can be configured as requirement, then after the slab that building mortion touches is partially-formed, the position that the part that the position that changes slab makes needs processing places building mortion to be worked into, the roller that the curve form that obtains after each roller of clamping device changes profile into and handles through each bending of building mortion matches or remain unchanged (if the part under the clamping device does not need building mortion processing), each roll axis position of clamping

synchronism slab of each roller of clamping device and building mortion moves reciprocatingly then, the part that building mortion processing waits to process reaches requirement up to the shape and size of this part.

C) plate that will have a plastic deformation ability cuts into the slab of definite shape, places the clamping device and the building mortion that are installed on the same fuselage then.Clamping device plays the clamping slab, drives the effect that slab moves reciprocatingly, and by two niprolls that can reciprocating rotating, two limit rollers are formed.The relative position of these niprolls and limit roller can be according to the clamping slab, the needs that drive slab adjust, two niproll axis can be adjusted to parallel, upper and lower two niproll clamping slabs, two limit rollers are distributed in the slab below partly of the both sides on two niproll planes that axis determines.In clamping device, upper and lower two niprolls and both sides roller are respectively with two cover transmission device transmissions, upper and lower niproll drives big mouthful of slab, the osculum of the moving slab of limit roller strap, suitable speed governing by transmission device make big mouthful and osculum to move back and forth angular speed the same, make the slab part of each roller contact of clamping device become conical surface coverboard after handling through each bending, each roller of clamping device clamps slab and drives slab and does reciprocal moving then.For guaranteeing that upper and lower niproll fully contacts with slab, the niproll profile also allows with certain tapering.The effect of building mortion is to cooperate the driving slab to do stable the reciprocating motion with the roller of clamping device, in the process of slab outward flange motion slab being applied power at its roller makes slab produce the local buckling plastic deformation, by the forming rolls that is positioned at the slab top that can back and forth rotate, the first limit roller and the second limit roller that are positioned at the spinning roller of slab below and are distributed in the slab part below of the both sides, plane that preceding two roll axis are determined are respectively formed, the forming rolls of building mortion, spinning roller, the relative position of the first limit roller and the second limit roller can be adjusted, spinning roller is relative with forming rolls and leave certain distance therebetween, the axis of rotation coplane of two niprolls of the axis of rotation of forming rolls and spinning roller and clamping device, the angle of forming rolls and spinning roller axis adjusts the revolution of the roller in the stream oriented device according to the needs that are shaped in sheet forming process, direction, machinery is adopted in the change of position and adjustment--and electric, pneumatic or full hydraulic drive.When the big so that insufficient rigidity of the curved shell plate part after being shaped of the curved shell plate size of required processing when guaranteeing when it moves reciprocatingly, plastic deformation not to take place, between clamping device and building mortion, be provided with by roller or its analog, as roller etc., the curved shell plate part that the bearing bracket of forming has been shaped, make when building mortion processing slab other parts, plastic deformation does not take place in the curved shell plate part that has been shaped.In building mortion, adjust each roller position and they are contacted and the power that applies makes the plastic deformation that bends of the part of slab under the building mortion roller with slab.When each roller turns round in the building mortion, do reciprocal moving with the roller driven in synchronism slab of clamping device.If slab is parked in the arbitrary position in the process of moving back and forth, at each roller of building mortion in slab edge moving process, contact point between forming rolls and spinning roller and the slab will the plane that clamping device two niproll axis are determined on slab in (forming rolls of building mortion and spinning roller axis are also in this plane) track is described out, if track is the straightway on the straight line of conical shell surfaces externally and internally bus place under the clamping device niproll, then slab is at clamping device, when reciprocatingly moving under the building mortion roller driven in synchronism, be subjected to part after each bending of building mortion is handled for can open up conical surface coverboard, if this track is a curve, then slab is at clamping device, and being subjected to the part after each bending of building mortion is handled in the process that reciprocatingly moves under the building mortion roller driven in synchronism is the curved shell plate that can not open up.If all parts or the clamping device of slab, the part that building mortion does not touch needs building mortion processing to handle the shape and size that just can be configured as requirement, then building mortion touch slab partially-formed after, the position that the part that the position that changes slab makes needs processing places building mortion to be worked into, each roller of clamping device changes roller or remain unchanged (if clamping device part does not down need building mortion to process) that the curve form that obtains after profile and each roller of building mortion are handled plate bending matches into, each roll axis position of clamping device obtains adjusting and makes each roller contacted by retained part with the curved shell plate that is shaped and apply power clamping slab, roller driven in synchronism slab with building mortion moves reciprocatingly then, the part that building mortion processing waits to process reaches requirement up to the shape and size of this part.

D) plate that will have a plastic deformation ability cuts into the slab of definite shape, places the clamping device and the building mortion that are installed on the same fuselage then.Clamping device plays the clamping slab, drives the effect that slab moves reciprocatingly, and the retained part of clamping device is by two disk-like object of back and forth rotating around dead axle, and promptly two clamping disks are formed.Slab places upper and lower clamping disk to clamp.The effect of building mortion is to cooperate the driving slab to do stable the reciprocating motion with the clamping disk of clamping device, in the process of slab outward flange motion, slab is applied power at its roller and make slab produce the local buckling plastic deformation, form by the forming rolls that is positioned at the slab top that can back and forth rotate, the first limit roller and the second limit roller that are positioned at the spinning roller of slab below and are distributed in the slab part below of the both sides, plane that preceding two roll axis are determined respectively.The relative position of the forming rolls of building mortion, spinning roller, the first limit roller and the second limit roller can be adjusted, spinning roller is relative with forming rolls and leave certain distance therebetween, the axis of rotation coplane of two niprolls of the axis of rotation of forming rolls and spinning roller and clamping device, the angle of forming rolls and spinning roller axis adjust according to the needs that are shaped in sheet forming process.Machinery--electric, pneumatic or full hydraulic drive is adopted in the change of the revolution of the roller in the stream oriented device, direction, position and adjustment.When the big so that insufficient rigidity of the curved shell plate part after being shaped of the curved shell plate size of required processing when guaranteeing when it moves reciprocatingly, plastic deformation not to take place, between clamping device and building mortion, be provided with by roller or its analog, as roller etc., the curved shell plate part that the bearing bracket of forming has been shaped, make when building mortion processing slab other parts, plastic deformation does not take place in the curved shell plate part that has been shaped.Adjustment clamping device clamping disk makes it clamp slab and drives slab does reciprocal dead axle swing.Contact with slab after the adjustment of building mortion roller and slab is applied power, spinning roller pushes slab to forming rolls, spinning roller, the clamping disk cooperation of forming rolls and clamping slab applies moment of flexure to slab, make the flexural deformation in slab generation forming rolls and the plane, spinning roller axis place, the axis of rotation coplane of two clamping disks of the axis of rotation of forming rolls and spinning roller and clamping device, the first limit roller and the second limit roller cooperate with forming rolls and spinning roller and slab is applied moment of flexure make slab produce local buckling distortion in another plane, thereby the part of slab in building mortion occurs bending and deformation, the clamping disk driven in synchronism slab of reciprocal forward and reverse when revolution of building mortion roller and clamping device is around the dead axle reciprocally swinging, or the building mortion roller drives slab separately and does dead axle swing, clamping disk only plays clamping action, the building mortion roller moves to the edge of slab simultaneously, the relative position of each roller of building mortion adjusts accordingly according to the needs of the variation of the different position curvature of curved shell plate, and the plastic zone constantly enlarges in this process.In the plane that axis of rotation determined of the axis of rotation of forming rolls, spinning roller and clamping disk, if each roller of building mortion contacts with slab, the track of contact point is a straight line on the slab, then slab is the circular cone coverboard that can open up after building mortion roller bending machining is handled, if track is a curve, then become the curved shell plate that to open up.

9) when the radius of curvature of the curved shell plate of need processing less, be processed into the required deflection of curved shell plate when big by the plane slab, whole slab is curved the curved shell plate (as cylinder coverboard or conical surface coverboard) that can open up in advance on common bent plate equipment, be placed on then and be processed into the curved shell plate that to open up in clamping device and the building mortion.

10) when the radius of curvature of the curved shell plate of need processing less, to such an extent as to (when slab moved back and forth, each roller of building mortion was called a passage from the process that initial position moves on to the slab transverse edge in a passage to be processed into the big building mortion of the required deflection of curved shell plate by the plane slab.) when being difficult to make slab to be configured as the shape of needs, forming process being divided into some passages carrying out.Each passage reaches the certain deformation amount, and progressive forming is through obtaining final shape and size after the accumulation of several passages.

The plate that adopts the present invention to process is that carbon steel sheet, aluminium sheet, copper coin, corrosion resistant plate or other have the plate of plastic deformation ability.The slab shape is a rectangle, circle, fan-shaped or other near rectangle, circle, shape such as fan-shaped.According to the plate thickness size, the height of material plasticity determines to adopt cold forming, warm working or hot forming.

Figure 12 is that slab is clamped in the schematic diagram among clamping device VII and the building mortion VIII.Arrow among the figure is represented the direction of motion of supporting of rest roller and the roller gyratory directions around self axis.The niproll of clamping device is positioned at the middle part of width of plate slab direction, each roller of building mortion is on the right of clamping device, rectangular coordinate system oxyz is used to illustrate the position of distortion and motion generation, the planes overlapping of the upper and lower niproll axis decision of xoy coordinate surface and clamping device.

The niproll 27,28 of clamping device VII clamps slab at the width of slab, removes in the clamping device outside the niproll 27,28, also has two rollers, and promptly the limit roller 29,30.Figure 13 is the distribution schematic diagram that dissects the relative slab of roller of slab gained with the plane that is parallel to coordinate surface yoz.The axis of each roller is parallel and around self axis reciprocating rotating, under driving, corresponding mechanism can also move and adjust, adjust limit roller 29,30 position, make roller 29,30 are higher than the position of roller 28 and the contact point of slab with the contact point of slab, make slab produce the corresponding centre of sphere section radius of a circle that radius of curvature after the flexural deformation equals the ball coverboard in being parallel to coordinate surface yoz plane.This flexural deformation is local, and when slab is moved back and forth by the driving of clamping device roller, the local plastic district will progressively expand to the slab various piece that the clamping device roller can touch.

Building mortion VIII is made up of the first limit roller 34 and the second limit roller 35 that are distributed in the both sides on plane that first three roll axis determines, slab below around the forming rolls 31 of self axis reciprocating rotating, counter-pressure cylinder 32, spinning roller 33, respectively.When needs are strengthened roller to the bending effect of slab with when guaranteeing the shaping at slab edge, above the both sides on forming rolls and spinning roller plane that axis determines slab part, pacify respectively again and ranked third limit roller and the 4th limit roller, or below the slab part of the both sides on forming rolls and spinning roller plane that axis determines, increase by the 5th limit roller and hexagon roller respectively, and be positioned at the outside of the first limit roller 34 and the second limit roller 35, or two kinds of situations occur simultaneously.The axis of rotation coplane of the axis of rotation of the forming rolls in the building mortion, counter-pressure cylinder and spinning roller and the niproll of clamping device.In the plane that is parallel to coordinate surface yoz, each roller will apply power with the slab contact position, adjust the position of each roller and slab contact point, make slab in the plane that is parallel to coordinate surface yoz, produce flexural deformation, and in, outer surface curvature radius equal the ball coverboard in respective planes corresponding in, the radius of curvature of outer surface circular arc, for example when forming rolls 31, spinning roller 33, the first limit roller 34 and the second limit roller 35 are in the coordinate surface yoz with the contact point of slab, when the power that these rollers apply slab bends slab in this plane, make in it, outer surface camber line radius of curvature equal the ball coverboard in this plane corresponding in, outer surface circular arc radius of curvature, as shown in figure 14.
