Abstract
The utility model discloses a medium frequency induction bent pipe heating coil, which comprises an outer layer coil (1) and an inner layer coil (2) which are fixedly connected with each other and communicated with each other through the through holes (3) uniformly formed in the outer layer coil (1) and the inner layer coil (2), wherein a plurality of water spraying holes (4) which are distributed at equal intervals are formed on the inner side of the inner layer coil (2); a water inlet (5) and a water outlet (6) are respectively formed at two ends of a folded part of the outer layer coil (1); and a water supplementation pipe (7) is connected to the outer wall of the outer layer coil (1). When the medium frequency induction bent pipe heating coil is used, cooling water enters the outer layer coil (1) and enters the inner layer coil (2) through the through holes, so that the water spraying branch pressures of the water spraying holes in the inner layer coil are balanced; the water supplementation pipe is connected to the outer wall of the outer layer coil, so that the water spraying pressure of the coil is increased by increasing the input amount of the cooling water, and thereby quenching capacity on a bent pipe is improved; and therefore, the performance of the bent pipe is guaranteed. A dual-coil device is difficult to deform during working, so that stress and deformation of the bent pipe during bending are more uniform; the wall of the pipe is uniformly heated; and the quality of a product is more stable.
Description
Technical field
The utility model belongs to the device of Frequency Induction Heating metal winding pipe, is a kind of coil of heating bend particularly.
Background technology
Intermediate frequency electromagnetic induction heating bend pipe is with the pipe localized heating, under the action condition of extrapolability, carries out bending.In this technology, heating-up temperature scope and cooling rate are that decision bends the good and bad key factor of performance after the moulding.Current, along with the development of project engineering construction, need the bend pipe diameter of usefulness increasing, and produce the employed heater coil of bend pipe along with the increase of diameter its deflection when the work is also increasing.In the prior art; Intermediate frequency electromagnetic induction heating bend pipe all adopts the individual layer air core coil in single rectangular pipe, round tube cross section; The deficiency of its existence is: bend pipe production process heater coil produces shake, causes the unsteadiness of operation, influences the heating-up temperature of bend pipe and the quality of product then.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and a kind of improved Frequency Induction Heating bend pipe coil device is provided; Its structure is provided with rationally, has improved stability of coil, and it reduces shake when work; Reduce deflection; Reduce substandard products and waste product, guarantee that tube wall is heated evenly stabilized product quality.
For reaching above-mentioned purpose; The utility model is taked following technical scheme: the utility model includes: outer coil, inner coil; The two is fixedly connected together, and communicates through the through hole that is uniformly distributed with above the two, and the inboard of inner coil has some equally spaced hole for water sprayings; Outer coil is respectively equipped with water inlet, delivery port at the two ends of apposition position, and outer coil also is connected to filling pipe at the outer wall first line of a couplet.
The utility model is taked technique scheme; Has following beneficial effect: when the utility model uses; Cooling water is got at outer coil, get into inner coil through the through hole that is uniformly distributed with inner coil then, thus the balanced water spray dividing potential drop of each hole for water spraying of inner coil.Be connected with filling pipe on the layer line ring outer wall outside, improve the water spray pressure of coil through the input variable that increases cooling water, thereby improved through hardening ability, the performance of bend pipe is guaranteed bend pipe.Not yielding in the twin coil device busy; The heating endless belt of bend pipe is controlled in the same planar range territory, guarantees that bend pipe heating running stability of coil is strong, reduce shake; Reduce the winding deformation amount; Make the stressed and distortion of bend pipe in the process of bending more even, tube wall is heated evenly, and product quality is more stable.
