Abstract
The utility model relates to a pipe depression shaper. The utility model is characterized in that a hydraulic oil cylinder is arranged on a semicircle base; a piston of the oil cylinder is connected with an arc-shaped raising block provided with fins; a return spring is arranged between the cylinder body of the oil cylinder and the piston; an oil channel which is communicated with the oil cylinder and a high pressure oil pipe is arranged in the base. The pipe depression shaper has simple structure and convenient use process and makes use of the hydraulic theory to lead the arc-shaped raising block to easily raise the depression in the pipe so as to repair the defect of pipelines. Arc-shaped raising blocks of various sizes and a small quantity of bases of different radiuses can be arranged according to different inner diameters of pipelines, when in use, the arc-shaped raising blocks can be conveniently changed to adapt to different inner diameters of pipelines according to requirement.
Description
Technical field:
The utility model relates to a kind of apparatus for shaping, particularly a kind of hydraulic pressure apparatus for shaping of the pipe of depressed deformation being answered " circle ".
Background technology:
The scaffolding steel pipe that industrial various pipeline, especially building trade are used causes depression, flexural deformation often because of local external force effect, as its shaping not being restored, just can only scrap because of its distortion back intensity reduces, and causes bigger waste.At present, flexural deformation has arbor press with the pipeline straightening, but can't handle depressed deformation, thereby the pipeline bulk strength behind the aligning descends, and internal diameter of the pipeline diminishes.
Summary of the invention:
The purpose of this utility model be design a kind of can be with the depression jack-up of pipeline, make pipeline become the pipeline depression reshaper of circle.
The design feature of the utility model pipeline depression reshaper is that hydraulic jack is set on half circular base, the arc jacking block of connecting band wing plate on the piston of oil cylinder, be provided with back-moving spring between the cylinder body of oil cylinder and the piston, be provided with the oil duct that is communicated with oil cylinder and high-pressure oil pipe in the pedestal.
Design feature of the present utility model also is:
The cylinder body of pedestal and hydraulic jack is threaded, and is provided with the cylinder body sealing ring between pedestal and the cylinder body.
Top between piston and the cylinder body is provided with dust ring, the bottom is provided with piston packing, and the arc jacking block of band wing plate is fastened on the top of piston by fixed screw; The oil duct and the pipe joint of pedestal are threaded.。
The utility model is simple in structure, easy to use, utilizes the hydraulic principle, makes the arc jacking block can be easily from the depression jack-up of pipe interior with pipeline, and the pipe-repairing defective saves time, laborsaving, economizes on resources and fund.According to the difference of internal diameter of the pipeline, the arc jacking block of multiple size and the pedestal of a spot of different radii can be set, during use, can change the arc jacking block easily as required, to adapt to the internal diameter of different pipelines.The utility model also can be used for the depression reparation of various industrial small-bore precious metal pipes except the reparation that can be used for the building trade scaffolding steel pipe.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1, and peripheral dotted line is represented by the position after shaping pipeline and the arc jacking block jack-up among the figure.
Number in the figure: 1 pedestal, 2 cylinder bodies, 3 back-moving springs, 4 pistons, 5 fixed screws, 6 arc jacking blocks, 7 dust rings, 8 piston packings, 9 cylinder body sealing rings, 10 oil ducts, 11 pipe joints, 12 snap joints, 13 high-pressure oil pipes.
The specific embodiment:
Referring to Fig. 2, the cylinder body 2 of described pedestal 1 and hydraulic jack is threaded, and is provided with cylinder body sealing ring 9 between pedestal 1 and the cylinder body 2; Top between piston 4 and the cylinder body 2 is provided with dust ring 7, the bottom is provided with sealing ring 8; The arc jacking block 6 of band wing plate is fastened on the top of piston 4 by fixed screw 5.
Referring to Fig. 1, the oil duct 10 and the pipe joint 11 of pedestal 1 are threaded, and pipe joint 11 connects high-pressure oil pipe 13 quickly and easily by snap joint 12.During work, can the utility model that be connected on the high-pressure oil pipe 13 be put into pipeline by the distance of pipeline recess apart from the mouth of pipe, arc jacking block 6 is aligned recess, open high-pressure oil pump, piston 4 drives arc jacking blocks 6 jack-up of will caving in, pipe-repairing depression defect.
