Abstract
Square ratio-frequency welded tube induction coil, be sleeved on the steel pipe being squeezed between pipe device and steel pipe caulking roller of steel band on steel pipe high-frequency welder, this radio-frequency induction coil is become by square copper pipe processing, cross section is square, cooling water channel is left at middle part, be separately installed with water inlet pipe and outlet pipe at the two ends of radio-frequency induction coil, and the two ends of radio-frequency induction coil are connected with high frequency electric source.Adopt this technology, because radio-frequency induction coil is square, forming surface and face close to mode between the inner surface of radio-frequency induction coil and the periphery of welded tube, its close relative area increases, on radio-frequency induction coil, input current is constant, the high frequency induction current that increase close to area can make welded tube produce in the local of weld seam increases, and the welding heat that welded tube obtains is increased.Like this, when the welding heat that welded tube obtains is constant, adopt square radio-frequency induction coil, just can reduce the electric current inputted on coil, thus the power consumption of Welded tube production is declined greatly.
Description
Technical field
The utility model belongs to ratio-frequency welded tube technical field, relates to a kind of square ratio-frequency welded tube induction coil.
Background technology
Ratio-frequency welded tube technique is after steel band is squeezed into prefabricated pipe, utilize radio-frequency induction coil, produce high frequency electric in the local of prefabricated pipe, high frequency electric produces kelvin effect and kindred effect in this local, pipe seam is made to squeeze by high temperature melt in the process of holding together at compression roller, the technique of bonding one-tenth pipe.Kelvin effect is when conductor passes to alternating current, and the CURRENT DISTRIBUTION that conductor sections occurs is uneven, and current density is increased to surface gradually by conductor center, and most of electric current is only along a kind of physical phenomenon of conductor top layer flowing.Kindred effect be when high frequency electric in two conductors each other reverse flow or flow in a reciprocal conductor time, electric current can concentrate on conductor adjacent side flowing a kind of special physical phenomenon.
In prior art, radio-frequency induction coil is a circular tube structure made of copper, when radio-frequency induction coil perpendicular on prefabricated welded tube time, its radial direction is axial vertical with welded tube, formed between the inner headed face of radio-frequency induction coil and the periphery of welded tube line and face close to mode, its close area is less, and the high frequency electric causing welded tube to produce in the local of weld seam reduces, and the bonding electric current power consumption that welded tube is needed increases.
Summary of the invention
For in prior art, ratio-frequency welded tube induction coil configuration is circle, the problem that after coil is heated, energy consumption increases, the utility model provides a kind of square ratio-frequency welded tube induction coil, be sleeved on the steel pipe being squeezed between pipe device and steel pipe caulking roller of steel band on steel pipe high-frequency welder, this radio-frequency induction coil is become by square copper pipe processing, cross section is square, cooling water channel is left at middle part, be separately installed with water inlet pipe and outlet pipe at the two ends of radio-frequency induction coil, and the two ends of radio-frequency induction coil are connected with high frequency electric source.
Adopt the technical program, because radio-frequency induction coil is square, forming surface and face close to mode between the inner surface of radio-frequency induction coil and the periphery of welded tube, its close relative area increases, on radio-frequency induction coil, input current is constant, the high frequency induction current that increase close to area can make welded tube produce in the local of weld seam increases, and the welding heat that welded tube obtains is increased.Like this, when the welding heat that welded tube obtains is constant, adopt square radio-frequency induction coil, just can reduce the electric current inputted on coil, thus the power consumption of Welded tube production is declined greatly.To generate heat the current loss caused for reducing radio-frequency induction coil, passing into cooling water in the inside of radio-frequency induction coil, to reduce the loss of radio-frequency induction coil loop current.
