Embodiment Construction

[0024] An intermediate frequency heating device with heating and cooling functions provided in this embodiment includes an induction coil 1, wherein the top of the induction coil 1 is an alternating positive and negative electrode, and the induction coil 1 is provided with spray holes at intervals. The high-frequency insulating ceramics 2 are connected with water inlet pipes 3 between adjacent high-frequency insulating ceramics 2, and each water inlet pipe 3 communicates with the corresponding high-frequency insulating ceramics 2, and the water inlet pipes 3 are connected with a spray system for water supply.

[0025] The high-frequency insulating ceramic 2 divides the induction coil 1 into corresponding cooling areas. When the induction coil 1 heats the steel pipe and performs the subsequent bending process, the spray system supplies water to the water inlet pipe 3, and the water flow is sprayed from the high-frequency insulating ceramic 2. The hole sprays out and acts on the ...

Abstract

The invention discloses a bent pipe medium-frequency heating device with heating and cooling functions, and relates to the technical field of bent pipe manufacturing equipment. The bent pipe medium-frequency heating device with the heating and cooling functions comprises an induction coil, alternating positive and negative electrodes are arranged at the top of the induction coil, high-frequency insulating ceramics with spraying holes are arranged on the induction coil at intervals, a water inlet pipe is connected between every two adjacent high-frequency insulating ceramics, and each water inlet pipe communicates with the corresponding high-frequency insulating ceramics. The water inlet pipes are connected with a spraying system for supplying water. The induction coil is used for non-contact heating, the temperature rising speed is high, heating is uniform, and the temperature control precision is further improved; local heating can be achieved, control is easy, labor is saved, workpieces in complex shapes can be heated, and the application range is wide; a plurality of spraying water holes are formed in the high-frequency insulating ceramic in each area according to actual requirements, so that the problem that the temperature of the circumferential section of the steel pipe is not uniform is solved.

Description

technical field [0001] The invention relates to the technical field of bent pipe manufacturing equipment, in particular to a bent pipe intermediate frequency heating device with heating and cooling functions. Background technique [0002] With the adjustment of my country's crude oil flow and natural gas transportation, the demand for large-diameter elbow equipment is gradually increasing, and many large-diameter elbows need to be flexibly changed during construction. The induction heating pipe bending process is an important process of pipeline construction and an important project of large-diameter pipeline engineering. Its working principle is to use intermediate frequency power supply to heat the steel pipe, and at the same time push the steel pipe at a uniform speed, so that the heated part of the steel pipe walks along the preset track , forming an elbow with a certain radius of curvature and angle. [0003] Medium frequency induction heating mainly uses the method of...
