Description
Technical field
The utility model belongs to pipeline processing intermediate frequency power supply induction coil heating bend field.
Background technology
Medium frequency bending of pipe need export energy with induction coil, to reach the object of heating tube.It is made up of rectifier, impulse generator, intermediate-frequency transformer, induction coil (having hole for water spraying, fumarole above it) etc.Bend thin-walled tube and adopt induction coil individual pen water-spraying control technique, bend heavy wall pipe and adopt the jet process for cooling of induction coil individual pen, along with the increase of electric utility power station unit capacity, the pipe wall thickness of pipeline processing and the increase of radius, adopt the working ability of induction coil individual pen not adapt to processing request.
Summary of the invention
The utility model object is the not enough problem that can not adapt to processing request of working ability overcoming induction coil individual pen, provides a kind of multiturn induction coil being applied to medium frequency bending of pipe processing.
The multiturn induction coil of medium frequency bending of pipe processing that what the utility model provided be applied to, comprise individual pen induction coil, one group of turn-to-turn bracing frame is welded with at the outer weekly interval of single turn induction coil, connecting hole is had in the middle part of turn-to-turn bracing frame, installing insulating primary and secondary pad in connecting hole, two or three single turn induction coils are connected and fixed by turn-to-turn bracing frame screw and nut and form multiturn induction coil.Described turn-to-turn bracing frame is that nonmagnetic stainless steel is made, and prevents the inner induced-current that produces from causing bracing frame and induction coil to damage.Control the pitch of turn of induction coil by bracing frame adjustment simultaneously, the overall width of induction coil can be adjusted within the specific limits, induction coil can adapt to the bend pipe of plurality of specifications.
The quantity of described turn-to-turn bracing frame is 2 to 4.
Fig. 1 is shown in by the bracing frame that the multiturn induction coil making that the utility model provides adds turn-to-turn than single turn induction coil, and the insulating element of the bracing frame inside of turn-to-turn is shown in Fig. 3.Coupled together by individual pen by bracing frame and insulating element, two individual pens are two circle, and three are three circles, but exit is identical with single turn only has two.Induction coil material with 30 × 3 square copper pipe, the increase of the number of turn can cause frequency decrease, diathermanous effective to heavy wall pipe, and the induction coil application of multiturn improves the heating efficiency of intermediate frequency power supply, save a large amount of electric energy in pipeline processing simultaneously, make again working ability significantly improve.
The bracing frame that the multiturn induction coil that the utility model provides is applied is that the nonmagnetic stainless steel material of application is processed into, be bolted each circle, be convenient to load and unload adjustable pitch of turn, thus can one circle multiplex, change induction coil and bend pipe uneconomical problem one to one in the past.
Described turn-to-turn bracing frame is by the square copper pipe side of being made into copper groove and weld with square copper pipe, side's copper pipe electric conductor bends annular helical structure, inner water flowing cooling, turn-to-turn has the bracing frame of insulation to support and prevents turn-to-turn short circuit, and the square copper pipe that the induction coil of multiturn makes should meet the requirement of conductive section sum mechanical strength.Select the induction coil number of turn how many according to pipe processing wall thickness thickness, medium frequency bending of pipe induction coil is manufactured with certain condition requirement, the minimum 400HZ requirement of the operating frequency of intermediate frequency power supply should be met, intermediate-frequency transformer connects operating frequency that three circle induction coils the produce minimum close to intermediate frequency power supply operating frequency, and the multiturn induction coil that medium frequency bending of pipe uses is the scope of two circles or three circles.
advantage of the present utility model and beneficial effect:
The application value of multiturn induction coil, be that there is obvious energy saving effect, progress in tube bending technology and development, by the popularization of this technology of induction coil of multiturn, can make the tube bending industry energy conservation of China lower consumption, increase economic efficiency, the working ability of pipeline can be improved simultaneously on the basis of original intermediate frequency power supply capacity, improve the competitiveness of tube bending enterprise, reduce the consumption of tube bending electric energy, save the resource of country, cut the waste.

Detailed description of the invention
Embodiment
As shown in Figure 1, the multiturn induction coil of medium frequency bending of pipe processing that what the utility model provided be applied to, improve to form on the basis of individual pen induction coil, one group of nonmagnetic turn-to-turn bracing frame 1 is welded with at the outer weekly interval of single turn induction coil, connecting hole is had in the middle part of turn-to-turn bracing frame, installing insulating primary and secondary pad 2 in connecting hole, two or three single turn induction coils are connected and fixed by turn-to-turn bracing frame screw and nut and form multiturn induction coil, wherein two individual pens are two circle (see Fig. 3), three are three circles (see Fig. 4), but exit is identical with single turn only has two.Induction coil material with 30 × 3 square copper pipe, turn-to-turn bracing frame is by the square copper pipe side of being made into copper groove and weld with square copper pipe.
Effect: copper groove support is welded on induction coil copper pipe, the hole installing insulating primary and secondary pad opened in the middle of copper groove support, with the fixation of CARBURIZING FURNACE FOR STAINLESS FASTENER nut, plays the effect of the insulation supporting induction coil turn-to-turn interval and turn-to-turn.
The quantity of described turn-to-turn bracing frame is 2 to 4, and this example is 4.
The manufactured size of induction coil is decided by processed line size, the internal diameter of induction coil should be greater than process pipeline external diameter 40 ∽ 50mm, the width of induction coil is 1.5 times of process pipeline wall thickness, turn-to-turn size 5 ∽ about the 10mm of induction coil, guarantee turn-to-turn insulation is good, insulation primary and secondary paves the insulating effect of turn-to-turn, and bracing frame and stainless steel bolt nut play the effect of the intensity of induction coil.
applicating example
1, eastern pot Ф 508mm × 78mm pipe processed by two circle induction coil
The 813 bending machines process of two circle induction coil bending process east pot Ф 508mm × 78mm pipe, intermediate frequency power supply power is 160KW.
2, three circle induction coil processing ID349mm х 103mmP92 pipes
1200 bending machines, three circle induction coils bend in the process of pipe bending ID349mm х 103mmP92 pipeline, and intermediate frequency power supply power is 140KW.
As shown in Figure 4.
By the comparison example of two kinds of induction coil heating tube above, multiturn induction coil working ability is far beyond original medium-frequency pipe bender technical specification, not only there is energy-saving effect obvious, and improve intermediate frequency power supply working ability, multiturn induction coil technology is used to produce energy-efficient effect when pipeline processing bends thick-walled pipe, the lifting of pipeline processing ability improves the living space that building and repair plant further develops, and improves building and repair plant's pipeline processing and bends the higher economic benefit of middle creation.
