It preferably, is 8-10 to the number for carrying out finish coatings via the wire rod after step 5) processing in the step 6)
It is secondary.
The beneficial effects of the present invention are:
1), production of enamel wire method of the invention is that copper material is stretched to wire rod final diameter by wire drawing twice, then
After annealing is first cleaned, is directly painted and is baked and banked up with earth after the cooling period, finally via being wound after lubrication, to obtain finished product enamel-cover
Line.The enameled wire produced via this method, the indexs such as tensile strength, elongation, softening breakdown are obviously improved, are protected
It has demonstrate,proved enameled wire other indexs while electric conductivity index is met the requirements and has also been able to satisfy use demand.This method step is closed
Reason, it is high in machining efficiency, it may make that the production efficiency of enameled wire and final product quality can be promoted effectively.
Based on the above method, the present invention also further improves existing component, so that it is in performance
It is significantly superior in existing corresponding component, it is as follows:
A, conventional lubrication coating unit, need to be by entire work since lubricating box is monolithic construction when replacing felt
The wholly off ability of skill process production technique is replaceable.The present invention is by being designed as fixed block and work for the monoblock type lubricating box of script
The Demountable of motion block, so as to be filled so that lubricating when required by removing movable block and then directly exposing groove
It sets even if still can at any time replace felt during the work time, whole process is not necessarily to shutdown operation, and using effect is more preferable.
B, on the basis of the said structure, synchronous also improves take-up the present invention.On the one hand, the present invention cancels
On wobble wheel close to switch, will be rotary switch close to switch change-over.On the other hand, it is direct traditional wobble wheel has been abandoned
The intrinsic construction close to switch is rigidly fixed, and by rotary switch setting on servo-actuated bull stick.Servo-actuated bull stick is arranged in wobble wheel
Side, and servo-actuated bull stick is parallel with the horizontal sliding guide rail where wobble wheel.In actual work, by being set on wobble wheel
Wiper arm is set, wiper arm can stir servo-actuated bull stick when following wobble wheel to be moved forward and backward and generate rotational action.Positioned at servo-actuated bull stick one end
The rotary switch at place can sense the amount of spin of servo-actuated wiper arm, and rotary switch then can be big according to the rotation amplitude of servo-actuated bull stick later
It is small, and different size of driving signal is issued to the driving motor that driving take-up reel rotates, finally realize normal winding displacement take-up mesh
's.It due to having abandoned close switch, then uses rotary switch to arrange in pairs or groups and is servo-actuated the structure of bull stick, so that guide pad and induction
Sensitive switch sensor is separated from each other, and is no longer presented the state of rigidly fixing.In this way, enameled wire affects wobble wheel and guiding
When block itself generates operational vibration, vibration directly rigid of transmission also will not ensure that rotary switch to rotary switch
Working sensitivity and service life.Further, since rotary switch can directly be fixed at the machine frame of wire drawing machine as static element and
Without being fixed at the moving parts such as guide pad, therefore conducting wire fretting wear problem is also just not present, practical wiring is also more square
Just.Meanwhile wiper arm spiral groove at servo-actuated bull stick, drive servo-actuated bull stick to generate revolution movement therewith, work operation is made an uproar
Sound is low, without significantly slap and vibrating noise.Meanwhile rotary switch impression be servo-actuated bull stick rotation amplitude, and therewith
Corresponding signal is issued to driving motor, this makes entire commutation process extremely flexible, reliable operation and stablize.
2), as the further preferred scheme of above scheme, C-shaped channel shape is presented in the cross section of spiral groove, thus for ball
Head is caught in, act so that bulb exert a force and servo-actuated bull stick is pushed to generate revolution, and is kept away with the necking down slot structure of spiral groove
Exempt from bulb and undesirably falls off spiral groove at work.It is and further, it might even be possible to which that the matching design by wiper arm and bulb is
Bearing turns round fit system, the cooperation of wiper arm and spiral groove is also changed into rolling cooperation with optical axis, thus a side
Face reduces the wear rate of spiral groove, and then promotes the service life of servo-actuated bull stick；On the other hand, rolling cooperation can be brought higher
Work flexibility ratio, and then promote servo-actuated bull stick to the action induction degree of wobble wheel, it is efficient finally to ensure that the present invention works
Property.
3), wiper arm is also attached at the back wall surface of guide pad, to avoid its installation and path of motion and guide pad
Path of motion between generate interference.The setting of brace, so that the cantilever beam construction of wiper arm script is by more stable gusseted
It is limited, to promote the structural rigidity of wiper arm, promotes its functional reliability therewith.
4), for being tensioned control assembly, when wire-arranging component pull enameled wire and when along take-up reel winding displacement, such as take-up reel
Take-up is too fast, and the movement of the traveling to side, namely guide pad at this time can be generated therewith by being tensioned the wobble wheel at control assembly at this time
It can be pulled and generate unidirectional sliding along horizontal sliding component.And when servo-actuated bar rotation amplitude reaches designated value, rotation is opened
Pass sends a signal to driving motor at take-up reel, makes its reduction of speed, guide pad itself can not reset at this time.Therefore, this hair
It is bright to add reset assembly, by the cylinder with no pollution to the environment as power source, and resetted with multiple tracks deflecting wheel
The deflecting and drawing of rope, and then realize that controllable wobble wheel resets purpose, reasonable and compact in structure works sensitive and stablizes.
5), since the spray head of traditional lubricating arrangement is arranged in through-hole, causing periodic cleaning and replacement spray head to need will be whole
A process flow is all closed, time-consuming and laborious.The present invention is by being arranged in spray head is independent right above through-hole, or even in reality
Demountable can be set by spray head when operation, even if so that the spray head still can be replaced during the work time.
Can be to be a variety of as the disassembly mode of spray head, such as bolt fastening even flange assembly can be achieved, and not be described in more detail here.
6), as through-hole, it is preferably arranged as top nose end arrangement outer chamfer, namely makes via top that expanding shape be presented；
The purpose of the design is to expand the aperture of the top nose end of through-hole, so that the extra lubricating fluid for from top to bottom spraying and dripping
And it is excessively applied to the lubricating fluid of wire surface, it after felt is scraped and sputtered by force, is remaining to be attributed at felt and quilt
Felt absorption is fallen, thus generation the case where reduce lubricating fluid splash.
7), when being confirmed whether to replace felt, can only observe felt by the opening of top is traditional lubricating arrangement
It is no that there is more impurity, when hardly realizing that lower section felt has more impurity, can still scratch be caused to components such as composition grooves, therefore
The present invention opens up jagged to form peep hole in bottom portion of groove, during the work time in order to staff, can be by this
Whether notch confirmation felt bottom has more impurity, to be replaced in time.
8) it, is fixed at the outer lateral box wall of liquid storage box due to movable block by hinge, movable block is extracting fixed block
Afterwards, movable block can be made not easy to lose under the action of hinge without falling.
