Be example with the coiling D-coil below, pre-bending mechanism and the operation principle that connects around mechanism be described:
Behind the free circle of the pre-bending 1-2 of a pre-bending mechanism D-coil, the company of entering is fixing in the coil die of mechanism.The geometric center point (being the geometric center point of coil die) of setting D-coil is a rotation center, and when conductor carried out coiling with linear velocity v, coil was with corresponding angular speed f (v) rotation.According to the technological requirement of coil winding, the pre-bending of conductor point should be on the position, point of contact of conductor coils circular arc all the time.When D-coil when geometric center point is rotated, the setting tangential direction immobilizes, then point of contact (being the pre-bending point) is not changeless, makes Descartes's rectangular coordinate system on plane, movement locus place, point of contact, and then the movement locus at point of contact can decompose by two rectilinear motions synthetic.
See also Fig. 4.Geometric center point with the D deltoid is that initial point is made rectangular coordinate system, an X axis left side, and Y-axis is upwards.To obtain the arc section at peaked some place on the curve in the X-axis positive direction, get its corresponding central coordinate of circle Oi (Xi, Yi), cross this point and make to be parallel to the straight line of X-axis, and meet at some A on the circular curve (x, y), then the OiA line segment is the radius of curvature R i of this arc section, (x y) is parallel to the point of contact of the tangent line of Y-axis to some A for this arc section.If central coordinate of circle Oi (Xi, Yi) and radius of curvature R i be known, then point of contact A (x, expression formula y) is:
X＝Xi+Ri，Y＝Yi
When the D deltoid is the center of circle counterclockwise behind the rotation alpha angle with the geometric center point, central coordinate of circle from Oi (Xi, Yi) move on to Oj (Xj, Yi), the point of contact from A (X, Y) move on to B (Xb, Yb), central coordinate of circle Oj (Xj, expression formula Yj) is:
Xj＝Xi*cos(α)-Yi*sin(α)，Yj＝Xi*sin(α)+Yi*cos(α)
Point of contact B (Xb, expression formula Yb) is:
Xb＝Xj+Ri＝Xi*cos(α)-Yi*sin(α)+Ri，Yb＝Yj＝Xi*sin(α)+Yi*cos(α)
For anglec of rotation α, the corresponding amount of movement in X-axis and Y-axis in point of contact is:
ΔX＝Xb-X＝Xi*cos(α)-Yi*sin(α)-Xi，ΔY＝Yb-Y＝Xi*sin(α)+Yi*cos(α)-Yi
So just can determine the anglec of rotation α of whole each arc section of D deltoid, the amount of movement Δ X and the Δ Y at point of contact.
In the coiling D-coil process, corner α realizes that by connecting around mechanism's panoramic table rotation point of contact amount of movement Δ Y realizes that by connecting around mechanism's panoramic table translation the amount of movement Δ X at point of contact is finished by the translation of pre-bending mechanism.Its technological process is: the pre-bending wheel is depressed action, the value of depressing is determined the corresponding conductor that changes α angle feeding certain-length around mechanism that connects of (first arc ab) → feed wheel by radius of curvature R 1, pre-bending mechanism follows the tracks of the X at point of contact, the above action of Y direction motion → repetition, until the coiling of finishing this segmental arc, enter next segmental arc → pre-bending wheel and depress action, the value of depressing is determined the corresponding conductor that changes α angle feeding certain-length around mechanism that connects of (second arc bd) → feed wheel by radius of curvature R 2, pre-bending mechanism follows the tracks of the X at point of contact, the motion of Y direction, repeat above action, until the coiling of finishing the R2 segmental arc.In like manner, finish R3 segmental arc (de), R4 segmental arc (ef).→ pre-bending samsara zero, the conductor of feed wheel feeding length of straigh line, finish the coiling of straightway (fg), enter next segmental arc → pre-bending wheel and depress action, the value of depressing is determined (the 5th arc ga) by radius of curvature R 5, finishes the 5th segmental arc → pre-bending mechanism by preceding method and gets back to next circle of starting point coiling.
The present invention presses following processing step coiling CICC coil:
Conductor cable laying → preliminary cleanings → conductor aligning → cross-sectional area of conductor dimension correction → cross section check → conductive surface blasting treatment → conductive surface cleaning → pre-bending moulding bends 1～2 free circle → bag turn-to-turn insulation → begin into each circle of mould → location → coiling lower floor → bag turn-to-turn insulation → go into mould → location → curve type and each circle of benefit circle → coiling upper strata → bag turn-to-turn insulation → go into mould → location → until finishing that upper strata coiling → benefit is justified and terminal processing → layer insulation and insulation against ground → going into dipping lacquer mould → later stage VPI processing until finishing the coiling → S of lower floor.
The technology of the present invention successfully is applied in the construction of country's 95 major scientific projects HT-7U superconducting tokamak devices, uses the model coil of the complicated D tee section of HT-7U of the technology of the present invention coiling, and positional precision is 0.6mm, and form accuracy is 0.8mm.This shows that aspect the winding technology and precision control of CICC coil, we have striden into the international rank of advanced units.
