Abstract
The utility model relates to a pipeline bending device, belonging to the technical field of machining of construction bent pipes of petroleum pipelines. The pipeline bending device is characterized in that a fixed holder and a rotary platform are arranged on a fixed platform; the rotary platform is connected with the fixed platform through a fixed rotor; and a roller is arranged on the bottom surface of the rotary platform; a high-frequency heater, a pressure-bearing rotor and a thrust lever are arranged on the rotary platform; and the fixed holder and the pressure-bearing rotor are respectively located at two sides of a high-frequency heating ring on the high-frequency heater. According to the pipeline bending device, compared with the prior bending art, the bending of a steel pipe, the nominal diameter of which is at least twice the curvature radius of an workpiece with any length, can be realized when the requirements to the machining quality standard of finished elbows are satisfied; the curvature radius is reduced, the influence to the performance of a steel pipe parent material is reduced, the production efficiency is improved and the working environment is promoted.
Description
Technical field
The utility model relates to a kind of pipeline simmering and bending device, belongs to petroleum pipeline construction elbow processing technique field.
Background technology
Bend pipe is a large amount of tubing that use in the pipe-line construction, and is one of important critical product.It plays main effect in pipeline; The one, change duct orientation; The 2nd, the structural mechanics effect; Can buffering pipe on-site stratum migration, earthquake and ambient temperature variation etc. be attached to drawing on the straight tube, compression and torsional interaction, the performance of bend pipe directly has influence on pipeline delivery reliability, security and economy.Therefore, the process technology of the bend pipe important that just seems.At present, the process technology of bend pipe also is mature on the whole, and still, the bend pipe of producing small curvature radius still adopts technologies such as artificial fire-heating elbow, hot extrusion processing.This production method firing rate is slow, heating is inhomogeneous, and the bend pipe radius of curvature is big, work situation is poor, influences the performance of steel pipe mother metal.
ZL 201020242171.2 discloses a kind of long distance pipeline small walled hot-bending bends ovality control device, is made up of handle, main body, movable slips, stationary slip four major parts; The semicircular main body lower end stationary slip that is connected, the upper end has nut to cooperate with the handle leading screw, and there is above-mentioned defective equally in the lower end of the leading screw activity slips that is connected.
Summary of the invention
The purpose of the utility model is exactly inhomogeneous to the heating of above-mentioned prior art existence, and the bend pipe radius of curvature is big, work situation is poor, influences the performance defect of steel pipe mother metal, and a kind of small curvature radius pipeline simmering and bending device of electromagnetism heating is provided.
The utility model is that fixed platform is provided with fixed clamp device and rotatable platform, and rotatable platform is connected with fixed platform through fixed rotor, and the rotatable platform bottom surface is provided with roller; Heating generator, pressure-bearing rotor and thrust lever are installed on the rotatable platform; Fixed clamp device and pressure-bearing rotor lay respectively at the both sides of the high-frequency heating ring on the heating generator.
Thrust lever is installed on the rotatable platform.
Between rotatable platform bottom surface and the fixed platform roller is installed.
The utility model and existing simmering and bending compared with techniques; Can satisfy under the finished product elbow crudy standard-required; Realize the steel pipe simmering and bending of the minimum twice nominal diameter of random length part curvature radius; Reduce its radius of curvature, reduce work situation is enhanced productivity, improved to the performance impact of steel pipe mother metal.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Can be known that by Fig. 1 the utility model is that fixed platform 7 is provided with fixed clamp device 2 and rotatable platform 3, rotatable platform 3 is connected with fixed platform 7 through fixed rotor 8, between rotatable platform 3 bottom surfaces and the fixed platform 7 roller is installed; Heating generator 4, pressure-bearing rotor 5 and thrust lever 9 are installed on the rotatable platform 3; Fixed clamp device 2 and pressure-bearing rotor 5 lay respectively at the both sides of the high-frequency heating ring 6 on the heating generator 4.
High-frequency heating ring 6 on the heating generator 4 is enclosed within treats on the crooked workpiece 1 high-frequency heating ring 6 places to be adjusted in the simmering and bending position; Adjustment treats that the distance between crooked workpiece 1 central shaft and fixed rotor 8 centers is to treat the radius of curvature of crooked workpiece 1, and will treat that with fixed clamp device 2 crooked workpiece fixes; Treating curved workpieces 1 by high-frequency heating ring 6 heats; Promoting rotatable platform 3 simultaneously rotates around fixed rotor 8; Treat curved workpieces 1 applied thrust through the pressure-bearing rotor 5 on the rotatable platform 3; Make curved workpieces 1 that even flexural deformation take place, to treating the processing of lowering the temperature of crooked workpiece 1 after the bending, can satisfy finished product elbow crudy standard-required at last.
