Abstract
The utility model relates to a mid-frequency heating device in a hot extrusion three-way pipe fitting, which comprises a heating coil connected with a mid-frequency heating control system, wherein a heating pipe coils along a cambered surface to form the shape of a spiral coil so as to form the heating coil; and the curvature radius of the cambered surface fits to the external radius of a pipeline that is heated. The mid-frequency heating device is adopted to heat a straight pipe blank of the hot extrusion three-way pipe fitting, so that equipment and technology are simple, the control is convenient, energy conservation and environmental protection are realized, energy utilization ratio can reach to 85 percent, and the heating can be carried out efficiently and rapidly.
Description
Technical field
The utility model relates to pipe fitting production equipment field, the especially frequency heating device of hot extrusion tee pipe fitting.
Background technology
Generally adopt tee pipe fitting as connector in the pipe-line system.Need adopt extrusion die to squeeze out arm then to the advanced row heating of straight tube blank when adopting hot extrusion technique extruding carbon steel, steel alloy tee pipe fitting in the production at straight tube one middle side part.Heating for straight tube only needs local heat, can adopt the gas heating and the method for furnace cupola heating that straight tube is carried out local heat at present: the gas heating is that the flame that utilizes fuel gas and oxygen mix burning to be produced is made thermal source, its shortcoming is that the temperature of flame is low, heat relatively disperses, and productivity ratio is low; The furnace cupola heating is the most original a kind of heating means, promptly adopts the coke and the processing work Direct Contact Heating of burning, and its shortcoming is that the temperature of heating is wayward, and atmosphere and environmental pollution are big, and energy waste is big.Another kind of scheme is to adopt heating of flame reverberatory furnace or resistance furnace heating that whole section straight tube heated earlier, take out whole section straight tube then, its mode such as side employing water-cooled that do not need to offer arm is lowered the temperature: the heating of flame reverberatory furnace is to adopt to make fuel with coal, diesel oil or combustion gas, and its shortcoming is that environmental pollution is big; Resistance furnace heating advantage is pollution-free.But not only technology is loaded down with trivial details for the mode of back two kinds of whole heating, local cooling, and the device space is big, and heat time heating time is long, and energy utilization rate is low, and the quenching technical that pipe fitting is lowered the temperature has been changed the structure property of product, has influenced product quality.
The utility model content
Shortcomings such as the applicant is unreasonable at the heating process of above-mentioned existing hot extrusion tee pipe fitting, and equipment energy consumption height, efficient are low provide a kind of frequency heating device of hot extrusion tee pipe fitting, exquisiteness simple in structure, and the efficiency of heating surface is high and pollution-free.
The technical scheme that the utility model adopted is as follows:
A kind of frequency heating device of hot extrusion tee pipe fitting comprises the heater coil that is connected with the heating in medium frequency control system, and described heater coil becomes the spiral coil shape by heating tube along the cambered surface dish, and the radius of curvature of described cambered surface matches with the outer radius that is heated pipeline.
The frequency heating device of hot extrusion tee pipe fitting, described spiral coil are shaped as one of square spiral coil shape, rectangle spiral coil shape, round screw thread loop-shaped.
Adopt the utility model that the straight tube blank of hot extrusion tee pipe fitting is heated, not only equipment and technology is simple, and control is convenient, and energy-conserving and environment-protective, and energy utilization rate can reach 85%, efficiently finishes heating fast.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
A kind of frequency heating device of hot extrusion tee pipe fitting comprises the heater coil that is connected with the heating in medium frequency control system, and described heater coil becomes the spiral coil shape by heating tube along the cambered surface dish, and the radius of curvature of described cambered surface matches with the outer radius that is heated pipeline.As Fig. 1, Fig. 2, shown in Figure 3, device described in the utility model is made up of heating in medium frequency control system, heater coil etc.Wherein the heating in medium frequency control system adopts PLC control panel and controllable silicon intermediate frequency device, is installed in control box 2 inside, the utility model bottom, and these technology are the known technology of heating in medium frequency equipment.Heater coil 1 is arranged on control box 2 tops, become the spiral round by copper pipe with the certain spacing dish, this spiral coil is not the plane, but turns to as shown in Figure 2 and the arc close curvature of shape that is heated outer diameter tube, the area of spiral coil with need the area heated area close.In specific embodiment, heat for GB Φ 325 arms, can adopt diameter is that Φ 20mm, wall thickness are the copper tube of 2mm, with the spacing of 3～6mm turn several 6～12 the circle heater coils 1.The spiral coil shape of heater coil 1 can be coiled becomes one of square spiral coil shape, rectangle spiral coil shape, round screw thread loop-shaped.
Actual working state of the present utility model is as shown in Figure 3: will need the straight tube blank 3 of hot extrusion tee pipe fitting to be placed in heater coil 1 top, utilizing the heating in medium frequency control system to connect power supply heats its zone to be heated by heater coil 1, after being heated to uniform temperature, straight tube blank 3 being transferred to carry out arm extruding on the hot extrusion tee pipe fitting mould.
More than describing is to explanation of the present utility model, is not the qualification to utility model, and the utility model institute restricted portion is referring to claim, and under the situation of spirit of the present utility model, the utility model can be done any type of modification.
Claims (2)
1. the frequency heating device of a hot extrusion tee pipe fitting, comprise the heater coil that is connected with the heating in medium frequency control system, it is characterized in that: described heater coil becomes the spiral coil shape by heating tube along the cambered surface dish, and the radius of curvature of described cambered surface matches with the outer radius that is heated pipeline.
