Background technology
Electric induction furnace is just developing into a kind of broad-spectrum smelting equipment.It is used for iron and steel smelting and non-ferrous metal mainly as melting furnace.In addition, also use as holding furnace.At present, induction furnace has replaced furnace cupola to become the capital equipment of Foundry Production aspect, compare with furnace cupola, the steel-making induction furnace has that hot metal composition and temperature are easy to control, the resultant of the gas in the foundry goods and field trash is low, free from environmental pollution, energy savings and improved many advantages such as working condition.
Therefore, induction furnace is developed rapidly in recent years.The important component part induction coil of induction furnace, its design is one of key of induction furnace, alternating current results from coil, coil has enough conductive cross-sectional area, to guarantee current strength, in addition the heat effects coil that produces of heavy current and smelting furnace service life, therefore need to adopt water cooled coil, coil method is designed to hollow and cools off in order to water flowing.
At present the induction furnace electromagnetic wire generally adopts the copper conductor of solid or side, rectangular hollow, and wall thickness is identical around the cross section.The lead of this form, under the high function of current of high pressure, the coil outer ring can will puncture copper pipe because of producing electric arc, causes the induction furnace damage even scraps, so will easily produce the thickness that the lead end face of electric arc increases its wall thickness.For this reason, the technical staff has proposed not wait 100 (as shown in Figure 1) of the eccentric copper pipe lead of rectangle of wall as induction coil, in order to replace existing prismatic copper conductor.
The process technology of the eccentric copper pipe lead of this kind rectangle 100 (as Fig. 1) is drawn for adopting extrusion tube blank to implement sky continuously.Cave in easily out-of-flatness and physical dimension deviation of the product rough inner surface that this mode is produced, outer surface is big.

Further, in the utility model, the connection of described fixedly core print is regulated section and is had axial hole, is provided with the internal thread of being convenient to be threaded in this axial hole.
Further, in the utility model, the die cavity rectangle sizing section length of described stretching external mold is 15mm-20mm.
Further, in the utility model, the modular angle of the distortion bevel phase of described die cavity is 6 °-8 °.
The eccentric copper pipe lead of the rectangle that adopts manufacturing of the present utility model to obtain has fineness and the good characteristics of precision.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is the schematic cross-section of the eccentric copper pipe lead of rectangle.
Fig. 2 is the structural representation of stretching external mold of the present utility model.
Fig. 3 is the structural representation of fixedly core print of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Induction converter induction coil is with the eccentric copper pipe lead of rectangle drawing die, comprises stretching external mold 200 and fixing core print 300.
Referring to Fig. 2, stretching external mold 200 comprises die sleeve 210 and core rod 220, and core rod adopts the YG8 material, and core rod 220 is embedded in the die sleeve 210.Be provided with die cavity 230 in the core rod 220, this die cavity 230 comprises the distortion bevel phase 231 and the die cavity rectangle sizing section 232 of taper.Distortion bevel phase 231 is pipe deformed areas in advance, and in the present embodiment, the modular angle of distortion bevel phase is 6 °-8 °.232 moulding of die cavity rectangle sizing section and finishing function, die cavity rectangle sizing section size is consistent with the outside dimension of the eccentric copper pipe lead of rectangle, die cavity rectangle sizing section and fixedly core print acting in conjunction, the eccentric copper pipe lead of the rectangle of acquisition required size.In the present embodiment, die cavity rectangle sizing section 232 length are 15mm-20mm.In addition, die sleeve is outer for to have 3 ° gradient, is convenient to adjust concentricity.
Referring to Fig. 3, fixedly core print 300 comprises the core print rectangle sizing section 330 that plays moulding and finishing function that the connection that is used for being connected with external driver device is regulated section 310, is connected adjusting section connection inclined changeover portion 320 with this and is connected with the chamfered transition section.Fixedly the connection of core print is regulated section 310 and is had axial hole 311, is provided with the internal thread of being convenient to be threaded 312 in this axial hole.The endoporus consistent size of the eccentric copper pipe lead of core print rectangle sizing section size and rectangle.
When stretching, fixedly core print is connected with fixing core bar, and fixedly mainly locate by adjusting fixedly core bar the position of the core print rectangle sizing section of core print, and the connection adjusting section can be finely tuned accurate the location.Consider that fixedly core bar can produce certain elastic deformation under big tensile force effect, so in adjustment fixedly during the core print position, fixing core print position slow astern segment distance in advance.
Produce the eccentric copper pipe lead of rectangle and comprise the twice drawing process, promptly push eccentric pipe and stretch through middle one transition, end product stretches; Twice stretch and all adopt the fixed core die drawing to stretch.The stretching lengthening coefficient is 1.2-1.3, and the external diameter decrement is between 12%-20%.It mainly is to subtract wall and wall thickness is rectified a deviation pushing eccentric copper pipe base tube reducing that middle one transition stretches, and will push eccentric pipe aligning simultaneously, is the finished product more good condition of creation that stretches.Stretch further tube reducing and subtract wall of the second road finished product obtains the eccentric copper pipe lead of rectangle that surfaces externally and internally is bright and clean, dimensional accuracy is high.
Because the eccentric copper pipe conductor material of rectangle winding needs relatively long length, and coil section is long-pending also bigger, therefore stretcher must have enough tonnages and length, just because of this, during stretching the fixing adjustment of the position of core print and stretching external mold is brought difficulty.Long fixedly core print, fixing core bar under big tensile force effect, can produce strain, make that fixedly the sizing position of core print moves forward and influences stretching condition, finally cause the drawn products hole enlargement, increase defective such as wall thickness.The utility model is considered this technological difficulties, adopt connection adjusting that fixing core print is connected with fixing core bar section can finely tune fixedly core print position, also have, fixedly preset lead in the core print process in adjustment, guarantee that fixedly the core print rectangle sizing section of core print is in the die cavity rectangle sizing section of stretching external mold.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in the foregoing description and the specification is principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in the claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
