Technical field
The present invention relates to light-wall pipe and simmer plumber's skill and device, its pipeline belonging to shipbuilding industry thin wall pipelines system makes field.
Background technology
Simmer the pipeline that pipe device makes, be characterized in replacing the elbow in each pipe-line system, greatly reduce the weld seam weld bond in pipe-line system, improve the quality of each pipe-line system. The problems such as present domestic bending pipe machine and import bending pipe machine, occur giving a discount when making bending for light-wall pipe, bulge, do not reach technology production requirement. Especially when the pipeline of the copper nickel B10 thin wall pipelines system of ships used for military purposes makes, it is desirable to reduction is less than 10, and existing equipment cannot realize. The operation principle of existing equipment is that in pipe, mandrel is motionless by clamping pipe fitting front end, and during work, pipe is along with mold disc spins, when pipe along with mold spirals forward certain angle to after, in its pipe, mandrel is just inoperative, cause pipe bending section occur give a discount.
Summary of the invention
In view of the defect that prior art exists, the present invention provides light-wall pipe to simmer plumber's skill and device, light-wall pipe is adopted and dynamically simmers plumber's skill, move when mandrel is with thin-walled tube bending, in thin-walled tube bending process, no matter thin-walled tube bending is to which angle, mandrel works at bending point always, improving the quality of dog leg piping, reduction is less than 10.
For achieving the above object, the technical solution adopted in the present invention is that plumber's skill simmered by light-wall pipe, and pipe fitting one end is enclosed within mandrel, for front end; Mandrel head end in pipe fitting is positioned at stewing pipe starting position, and be fixedly clamped the pipe fitting other end, for rear end; The movement of the mold dish of mold and mold block restriction pipe fitting, mold block moves and forces pipe fitting to bend on mold dish circumference, and the head end of mandrel bends forward end with pipe fitting and moves; In pipe fitting BENDING PROCESS, simmering pipe active force and be applied to the front end of pipe fitting, pipe fitting is bent at any bending point, and the head end synchronizing moving of mandrel bends to bending point support tubes.
Pipe device simmered by light-wall pipe, being made up of workbench, mandrel, clamping device, mold, mold includes mold dish and mold block, and workbench arranges portable plate, portable plate arranges mold block, the central shaft of mold dish is fixed on workbench, and portable plate rotates with central shaft for axle, and clamping device is arranged on the table, including clamping block A, clamping block B and check lock lever, clamping block B is fixing on the table, and check lock lever promotes clamping block A to clamp pipe fitting one end near clamping block B, clamping block A and clamping block B;Arranging mandrel push rod, mandrel push rod connecting mandrel one end on portable plate, mandrel matches with pipe fitting, the pipe fitting other end is enclosed within mandrel, and mandrel push rod promotes mandrel to move in pipe fitting, and the mandrel other end is provided with bulb, bulb moves to pipe fitting position to be bent, and portable plate arranges lever push rod; Promoting lever push rod to drive portable plate to rotate, mold block compressing pipe fitting bends to mold dish, and core moves axially away from clamping device position simultaneously, and in pushing course, pipe fitting bending point moves to away from pipe fitting pinching end, and bulb synchronizing moving is maintained at pipe fitting bending point. Described mold block is movable part, and relative mold dish side arranges semicircular arc groove, matches with pipe fitting, face contact pipe fitting; Mold block opposite side is bolted on portable plate. Described mold dish semicircular arc groove provided circumferentially about, matches with pipe fitting, and the face, position after bending with pipe fitting contacts. Described lever push rod is connected with cylinder or hydraulic cylinder, provides power by cylinder or hydraulic cylinder, drives portable plate to rotate. Described bulb is spherical, is connected with mandrel by universal joint. Described mold dish arranges angle display panel, the angle value that display portable plate rotates. The described portable plate anglec of rotation is 0-270 ��, and the angle of bend of pipe fitting is 0-270 ��.
Light-wall pipe, makes hollow billet by steel ingot or solid pipe billet perforated, then makes for hot rolled, cold rolling or cold group. Compared with prior art, the present invention is had an advantageous effect in that the pipeline for shipbuilding industry thin wall pipelines system makes, and particularly the pipeline of ships used for military purposes B10 thin wall pipelines system makes. It is characterized in replacing the elbow in each pipe-line system, greatly reduces the weld seam weld bond in pipe-line system, improve the quality of each pipe-line system.
