For solving the problem, the object of the present invention is to provide a kind of Novel elbow pipe heater, this heater is made up of the air-cooled circle be arranged side by side, induction heating circle and water-cooled circle, carrying out pipeline, stewing system is timely afterwards carries out water-cooled or air-cooled process to bending part, realize the Quenching Treatment of bend pipe, ensure that the quality of bend pipe.
For achieving the above object, a kind of Novel elbow pipe heater disclosed by the invention, it comprises the air-cooled circle, induction heating circle and the water-cooled circle that are arranged side by side; Air-cooled circle comprises air-cooled collar body, and the inwall of air-cooled collar body gathers multiple air outlet, and air outlet is communicated with the air inlet be arranged in described air-cooled collar body; Described water-cooled circle comprises water-cooled collar body, and the inwall of water-cooled collar body gathers multiple hole for water spraying, and hole for water spraying is communicated with the water inlet be arranged in described water-cooled collar body.
Further, described air-cooled circle, spacing between induction heating circle and water-cooled circle is adjustable.
Further, the lateral wall of described air-cooled circle, induction heating circle and water-cooled circle is provided with connecting plate, and connecting plate is provided with through hole; Utilize bolt and nut and connecting plate, described air-cooled circle, induction heating circle are fixedly connected with side by side with water-cooled circle.
Further, two described air inlets are symmetricly set on the both sides of described air-cooled collar body.
Further, two described water inlets are symmetricly set on the both sides of described water-cooled collar body.
Further, described air-cooled collar body and described water-cooled collar body are made up of two hemizonids respectively.
Further, described air-cooled collar body and described water-cooled collar body interior are annular space structure.
Further, the inwall of described air-cooled collar body is obliquely installed, and the air blown out from described air outlet tilts to described induction heating circle direction, and wind direction becomes 10 ° of angles with pipeline.
Further, the inwall of described water-cooled collar body is obliquely installed, and the water sprayed from described hole for water spraying is to angle in 90 ° with pipeline.
The present invention changes original single heating collar into three circles, effectively can control the heating surface area of bend pipe.The Forming Quality of bend pipe is controlled by control blowing and water spray angle, the 3D bend pipe utilizing this explained hereafter to go out, reduction controls within 6.8%, and ovality controls within 1.9%, than the reduction 9% of SY/T 5257-2012 regulation, technical parameter such as ellipticity 2.5% grade reduces 25%; After forming elbow, ovality and reduction all reduce 25% than SY/T5257 standard.
