Description
Technical field:
This utility model relates to rail vehicles and machinery manufacturing technology field, particularly relate to the cover plate edge of a wing welded corner joint deformation controller in hole by the fish belly type box-structure centre sill of growing up of plate Combination Welding in rolling stock manufacture, specifically, it is that the welded corner joint reversible deformation of a kind of box Cover Plate edge of a wing controls fixture.
Background technology:
The model produced at present is the central sill of the container flat car of Australia N80-AUS, N5-AUS is the typical fish belly box type structure girder of growing up being become variable cross-section by upper cover plate, lower cover and web assembly welding, as shown in Figure 1, central sill upper cover plate, lower cover, web material all adopt Q450NQR1 or Q550NQR1, upper cover plate thickness of slab t=14mm, lower cover thickness of slab t=16～18mm, it adopts full penetration with middle web (thickness of slab t=10～16mm) joint angle weld seam in crossbeam, sleeper beam and traction beam section, adopts ultrasound wave and magnetic powder detection.Because the input of complete molten multi-layer multi-pass welding heat is big and welder's skill operation reason etc. unavoidably exists Weld Seam Repairation, repeatedly it is heated to weld zone, cause that postwelding upper cover plate, lower cover reach about 5-7mm in crossbeam, sleeper beam and traction beam section Welding Angular Deformation, and design technology requires that upper cover plate, lower cover flatness are not more than 3mm, draw beam cartridge place lower cover flatness is less than 1mm.
The similar structures product in the past produced, upper cover plate, lower cover thickness t=8～12mm, material Q345B, all adopt following two process technology scheme to ensure that product meets design technology and requires for upper cover plate, lower cover: one is adopt cover plate mechanical pressing technology welded corner joint anti-deformation, upper cover plate adopts along angle welding position straight line mechanical compaction 4～6mm anti-deformation in upper operation blanking molding procedure, to offset the Welding Angular Deformation that welded corner joint brings, to meet upper cover plate planarity requirements；Two is adopt Manual flame heating correcting technology, the postwelding edge of a wing 4～6mm angular deformation of welding anti-distortion amount cannot be suppressed for central sill lower cover, jack is adopted to correct edge of a wing Welding Angular Deformation with the use of flame heating is manual, to reach lower cover flatness less than 1mm design technology requirement.
Because the central sill that model is Australia's N80-AUS, N5-AUS container flat car is fish belly variable section structure, its lower cover needs mechanical cross bending, thus mechanical means compacting welded corner joint anti-deformation cannot be adopted, and adopt Manual flame heating correcting technology, production efficiency is low, and labor intensity is big, and artificial material cost consumption is big, the factors such as operant skill make the surface quality after rectification rough and uneven in surface, and flatness not easily ensures.Therefore need the technology and pattern assembly inventing a kind of novel practical to ensure that manufactured product meets design technology requirement.
Summary of the invention:
The purpose of this utility model is in that to provide the welded corner joint reversible deformation of a kind of box Cover Plate edge of a wing to control fixture, its simple in construction, easy to operate, production efficiency is high, low cost of manufacture, box Cover Plate edge of a wing Welding Angular Deformation can be controlled, make the flatness of cover plate disclosure satisfy that design technology requirement.
To achieve these goals, this utility model adopts the following technical scheme that
This utility model provides the welded corner joint reversible deformation of a kind of box Cover Plate edge of a wing to control fixture, this welding anti-distortion controls fixture and includes screw clamp and self-locking plate beam type structure, screw clamp is combined into by helical screw, convex nut, screw rod bushing, movable ram, self-locking plate beam type structure is formed by two block self locking risers and the first connecting plate, the second connecting plate, the 3rd connecting plate assembly welding, first connecting plate, the second connecting plate, the 3rd connecting plate are arranged between two block self locking risers, self-locking riser two ends are bending, and folded end is hook；Screw rod bushing is fixed between two block self locking risers；Screw clamp is fixed in self-locking plate beam type structure by screw rod bushing.
Compared with prior art, this utility model has the beneficial effect that
1, this utility model solves capacity of equipment deficiency problem, suitable in manufacturing enterprise's small lot batch manufacture, or because capacity of equipment deficiency cannot adopt existing machinery method compacting cover plate welding anti-distortion amount and because design reasons in structure cannot adopt the manual manufacturing enterprise adding heat straightening technique to use, compared to existing technology, this utility model is adopted to weld, save the equipment that part preprocessings and subsequent corrective work bring in a large number such as mechanical compaction anti-deformation and craft heat straightening, manually, cost of raw materials used (one, upper operation upper cover plate, it is artificial that lower cover compacting reversible deformation produces, equipment loss, the costs such as fortune smash by material.Two, when steel construction central sill is corrected, artificial, instrument, the industry cost such as gas, oxygen of upper cover plate, lower cover angular deformation generation is corrected).This utility model instead of existing employing mechanical means compacting welding anti-distortion amount and adopts prior art jack to coordinate flame to add heat straightening cover plate edge of a wing Welding Angular Deformation technique.
2, this utility model is reusable, total is rationally distributed, simple in construction, lightweight, easy to operate, low cost of manufacture, practical, versatility is good, and it is reasonable, effective that active force and the counteracting force point of application are arranged, namely can operate with all have an analog structure and the different welded corner joint Deformation control of sectional dimension by adjusting the relative position of two helical clamping screw mandrels compositions.
3, the method for this utility model employing compacting reversible deformation can by weld industry inside welding sequence, avoid rear operation for ensureing that lid flatness meets design technology requirement, and adopt add the impact that mother metal mechanical performance is reduced by heat straightening technique, the upper cover plate of central sill, lower cover surface quality are good, flatness meets design requirement, without the manual top impression etc. corrected and produce, reach to improve product interior quality and appearance looks elegant, improve production efficiency, reduce staff labor intensity, reduce production cost further.
4, this utility model can be applied to fish belly molding box type center sill structure product batch production from now on and the control for similar Welding Angular Deformation.
