Description
Technical field
This utility model relates to tube panel bending field, particularly relates to a kind of boiler diaphragm type wall tube panel bending tool.
Background technology
Membrane wall is Application comparison parts widely on current boiler, the bending of tube panel is one of master operation of membrane wall manufacture, this operation major quality controlling point is: bending radius, bending position and ovality etc., wherein the control of ovality directly affects workmanship and the running quality of bone network.
There is no the horizontal tube panel bending machine of anti-deformation groove, owing to its bend pipe running roller is smooth roll, the outermost both sides pipe ovality almost all of the tube panel bending section being bent into exceeds standard, and must place under repair the place that exceeds standard before tube panel duplicate sample, both lost labor, also have impact on the presentation quality of tube panel simultaneously.
Tube panel welding procedure: after GB3375 acceptance(check) pressed by pipe, band steel, carries out the item work such as issuance of materials, blanking, pipe polishing rust-removal, band steel finishing, tube panel welding, the water pressure test according to quality management program, and its main processes is as follows:
Tube panel welding line confirms that bending starting point and bending terminal bending through ball test duplicate sample arrange flush water pressure test surface and process, protect (packaging) to be installed.
The steel pipe specification making membrane wall conventional is Φ 51*3mm and Φ 60*4mm, radius of curvature R=300mm, by standard-required R/D >=3.5, and logical bulb diameter d=0.9d；Φ 51*3mm pipe leads to bulb diameter Φ 40.5mm；Φ 60 × 4mm pipe leads to bulb diameter Φ 46.8mm.The tube panel made by process above flow process, outermost two tubes, ovality exceeds standard degree as a example by the pipe of Φ 60 × 4mm: big footpath × path=65.5 × 53.5mm, it is therefore necessary to increase by one reparing process, it may be assumed that
Tube panel welding line determines that bending starting point is repaired through ball test duplicate sample with bending terminal bending tube panel both sides pipe and arranged the process of flush water pressure test surface, protects (packaging) to be installed.
Add " reparation of tube panel both sides pipe " operation, too increase the artificial and process-cycle, destroy the surface quality of pipe simultaneously.
Study by analysis and observe BENDING PROCESS, find why outermost two tubes produces ovality and exceed standard, it is because smooth roll and outside tube is not had position constraint power, why ovality does not exceeds standard intermediate tube, and the rigid body being because the pipe outside it and band steel formation serves the effect of resistance to deformation to intermediate tube.
Utility model content
This utility model is mainly solving the technical problems that provide a kind of boiler diaphragm type wall tube panel bending tool, it is to avoid the ovality excessive problem of tube panel outermost pipe.
For solving above-mentioned technical problem, the technical scheme that this utility model uses is: provide a kind of boiler diaphragm type wall tube panel bending tool, including: bend pipe roller and membrane panel, described membrane panel is arranged on bend pipe roller, a fixing baffle ring and movable baffle ring it is arranged with on the cylindrical of described bend pipe roller, described membrane panel is arranged between fixing baffle ring and movable baffle ring, it is arranged with a regulating flange being positioned at outside movable baffle ring on the cylindrical of described bend pipe roller, is provided with a circle outside described regulating flange and is perpendicularly oriented to the regulation bolt of movable baffle ring.
In one preferred embodiment of this utility model, described membrane panel includes that several pipe and band steel, described band steel connect respectively and is arranged between adjacent two piece pipe.
In one preferred embodiment of this utility model, it is parallel to each other between described pipe.
In one preferred embodiment of this utility model, between described fixing baffle ring and bend pipe roller, employing is weldingly connected or bolt is connected.
In one preferred embodiment of this utility model, described regulation bolt annular array is arranged on the lateral surface of regulating flange.
