Embodiment
Embodiment 1, as shown in Figure 1, the electromagnetic brake coil of boring winch winding mould comprises the winding former that outer plate 1, clip plate 4, set bolt 2 constitute, adpting flange 5 is connected by taper hole, jackscrew with coil winding machine, clip plate 4 is fixed on the adpting flange 5 by being threaded, winding mold 3 is fixedlyed connected with clip plate 4 by screw thread, and outer plate 1 is fixedlyed connected with winding mold 3 by set bolt 2; And on this winding mold outer plate 1 and clip plate 4, be provided with technology groove.
In the coiling of coil, be connected, fix by taper hole, jackscrew with special-purpose coil winding machine by adpting flange shown in Figure 25, clip plate 4 is fixed on the adpting flange by being threaded, winding mold 3 is fixing by being threaded with clip plate 4, the line sending support is installed in the forward right side of coil winding machine by a slide rail, fix the beginning winding process after adjusting coiling moment with pressing plate.In winding process, kit is along with the coil winding machine spindle operation, and rotating speed is 5r/min.After finishing the coiling operation, outer plate 1 is fixing with counterdie after the coil stationary shaping with winding mold 3 usefulness set bolts 2, change next manufacturing process over to.
The adpting flange of Fig. 2 is a general part, is fixedly mounted on the coil winding machine; The winding mold 3 of accompanying drawing 3 can be changed according to coil specification difference.In order to reach the quality requirement of coil, the requirement on machining accuracy of winding mold 3 is controlled at 6 grades, and the bakelite that winding mold 3 is selected is not yielding, not have to damage to copper cash is done material and processed.
These coil winding technology concrete steps are as follows:
1) after coil winding machine, the line sending support that counter and stepless time adjustment motor will be installed installs, coil die adpting flange, clip plate and coil winding machine are connected and fixed;
2) on winding mold, put strapping in advance, belt one end is overhanging from the technology groove on the clip plate, be installed in the flat type copper wire for the treatment of coiling on the line sending support and adjust moment after begin coiling according to coil winding machine rotating speed 6r/min;
3) after coiling is finished, strapping tied up be bolted, install and fix outer plate 1, coil is carried out a shaping;
4) after the shaping, take off outer plate 1, coil counterdie pyrocondensation insulation wrapping;
5) coil behind the counterdie is at dipping lacquer pond dipping lacquer, and the insulating varnish rank is the F level;
6) behind the dipping lacquer, coil is dried according to the technology of design;
7) secondary pyrocondensation insulation wrapping;
8) secondary dipping lacquer;
9) secondary drying technical process,
10) at last coil is installed on the winding mold 3 at this, on coil winding machine, coil is carried out last shaping, make the deviation from circular from of coil be controlled in the whole diameter range of 0.05mm/.
11) technical parameter detects. be finished product.
With the DS32 coil is example, in coiling, after adpting flange 5, clip plate 4 and coil winding machine be connected and fixed, φ 857 * 60 winding molds are installed, and on winding mold 3, put strapping in advance, belt one end is overhanging from the technology groove on the clip plate 4, flat type copper wire is installed on the line sending support and after adjusting moment begin coiling.This specification coil needs coiling 13 circle/layers, altogether around 38 layers.Want single-deck of coiling at every layer, at last coiling 7 circle again after finishing 38 layers of coiling.In winding process, line sending and artificial group line enclose surely simultaneously and carry out automatically, guarantee that coil winding is neat.The number of turn is counted automatically by counter, and operating personnel take into account the single-deck of every circle and 7 last circle coilings simultaneously.After coiling is finished, strapping tied up be bolted, install and fix outer plate, coil is carried out a shaping.After the shaping, take off outer plate 1, with the coil counterdie.Coil behind the counterdie is at dipping lacquer pond dipping lacquer, and the insulation rank of lacquer is the F level.Behind the dipping lacquer, according to the technology of design to coil dry, technical processs such as secondary wrapping, secondary dipping lacquer, secondary drying, at last coil is installed on the winding mold at this, on coil winding machine, coil is carried out last shaping, make the deviation from circular from of coil be controlled in the whole diameter range of 0.05mm/.
The technique for coiling process of the coil of other specifications and the technique for coiling of DS32 coil are duplicate.Different is when the coil of coiling different size, because the internal diameter of coil is in different size, thus to change the winding mold of different size, and the coiling number of turn difference of each coil, with dimensional requirement and the performance requirement that reaches the different size coil.For example, the DS40/45 electromagnetic brake coil, its internal diameter is φ 1165,29 layers of coilings, the number of turn is the 13+1/ layer.
Present embodiment aborning, according to the design technique for coiling, solved the technological difficulties of electromagnetic brake coil in coiling such as DS20, DS32, DS40/45, DS50, DS60/70 fully, finished the processing and manufacturing of coil.
The technical process of present embodiment is: wire gauge selects and check → coiling → coil shaping → pyrocondensation insulation wrapping → dipping lacquer → oven dry → secondary pyrocondensation insulation wrapping → secondary dipping lacquer → secondary drying → coil molding → technical parameter detection → product completion.
Key technology difficult point wherein is the mould up and down and the shaping technique of coil.Finish the shaping of coil for reaching smooth mould up and down, when design technology, for reaching technological requirement, designed special-purpose copper cash line sending support, counter and stepless time adjustment motor have been installed on coil winding machine, and the rotating speed of design coil winding machine is 6r/min, to reach the moment requirement of coiling; Designed technology groove on the winding mold outer plate, the shaping on coil winding machine of coil that can coiling is good bandages the back counterdie.The insulate paint-dipping process of the laggard capable insulating varnish of wrapping of coil, insulating varnish adopts the F class F insulation, to reach the requirement of mechanical strength behind the dipping lacquer.
The coiling instrument is made up of coil winding machine, coil die, line sending support, when coiling, coil winding machine can be adjusted the coiling rotating speed automatically by the stepless time adjustment motor, automatically the line sending support can be regulated apart from the coil winding machine distance to reach the moment of coil winding, and the internal coil diameter and the circularity requirement after counterdie and the secondary reshaping of tying up of a shaping of coil just considered the time in the winding mold design of coiling mould, simultaneously in the selection of the selection of technology and insulating varnish, increase secondary dipping lacquer shaping process, selected the F class F insulation lacquer of higher level.Like this, the coil of coiling has overcome not up to standard, the quality problems such as mechanical strength is not enough, circularity over tolerance generation leakage field own of insulation that the outsourcing coil exists fully, has reduced coil in use easily to produce burning phenomenon, has improved the useful life of coil.
Technologies such as the dipping lacquer that the present invention taked, oven dry, its technological parameter all adopt industry required standard to carry out.
