Description

Electric barker for conducting wire

Electric barker for conducting wire is electronics, electrical equipment industry electric tool.The core technology is twisted with the fingers in the quick peeling that solves rubber lead in enormous quantities.

Present existing lead rosser has wire stripping pliers, simple and easy pocket peeler, electric heating peeler, the pocket peeler of pen type etc.Their common drawback is: power is all by manually providing, wire stripping speed is all slow, except the pocket peeler of pen type and, its excess-three kind peeling tool all can only peeling, can not twist with the fingers core, use above-mentioned four kinds of peeling tools, a skilled wire stripping worker, core speed is twisted with the fingers in normal peeling, eight the end of a thread of processing in one minute, quite nervous, in the industry, this is on record.

Indivedual electronic apparatus factories φ 4mm drill bit, cutting edge is ground to half garden shape, two drill bits make two and half garden shape drill bit cutting edges be paired into garden shape shape of threads edge to altogether, and cutting edge is eaten lead the end of a thread and entered required the end of a thread length (being generally about 5mm) during rotation.Lead is pulled, and the end of a thread rubber also peels, and heart yearn has also been twisted with the fingers, and speed is also brought up to 3-4 times of wire stripping pliers greatly, but because: (1) cutting edge serious wear influences the cutting edge life-span greatly.(2) eat the necessary regular hour of inlet wire head, generally wanting has influenced speed about 1 second.(3) main, the cutting edge gap can not be finely tuned, and often can only process a kind of lead of thickness specification.So this technology can not form commodity production and promote.

Power of the present invention is provided by motor, and peeling, sth. made by twisting core operation are united two into one the action clarity, improved efficient greatly, the end of a thread that skilled operators can be processed more than 60 in a minute, and also the length of the end of a thread is easy to control, it is even to twist with the fingers the core elasticity, does not hinder lead again.

Each sequence number of Fig. 1 is the part title in addition:

1. finely tune drive block 11. transparent guide covers

2. finely tune screw rod knob 12. guiding garden bars

3. motor casing 13. transparent cover clamps

4. 14. tubaeform pilot hole fixed heads are pitched in fine setting

5. motor output shaft 15. trim rings

6. axle sleeve 16. cutter head clamping plate

7. axle sleeve pressing plate 17. tubaeform pilot holes

8. carriage guide 18. cutter head rotating shafts

9. shell 19. cutter heads

10.y spring 20. knife rests

As Fig. 1, when motor output shaft 5 rotated, axle sleeve 6, carriage guide 8, knife rest 20, cutter head 19 rotated together, and cutter head 19 can rotate around cutter head rotating shaft 18 on knife rest 20.Its slewing area is subjected to the domatic restriction of knife rest 20 end notches again.When cutter head 19 does not have external force, when promptly pressure ring 15 touched, because action of centrifugal force, cutter head 19 got rid of on position shown in Fig. 1 solid line.Result of calculation, when motor speed was 2800 rev/mins, about 11 grams of the radial centrifugal force of single cutter head 19 were permitted, and trim ring 15 promotes cutter heads 19 and rotates around cutter head rotating shaft 18, and only about 4 grams, two cutter heads are about 4 gram * 2=8 restrain to the axial thrust load that need overcome cutter head centrifugal force.

Obviously, as Fig. 1, when cover clamp 13 be pushed turn left parallel when mobile (design thrust is not more than 30 grams), touch cutter head 19 by trim ring 15, be about to cutter head 19 and shift the position shown in the double dot dash line onto, the cutting edge of cutter head 19 promptly suits in opposite directions to the center, when on the cover board not having thrust, because the elastic force of y spring 10 by guiding garden bar 12, pushes up back shown position with cover clamp 13.Trim ring 15 breaks away from cutter head 19, and cutter head 19 gets rid of go back to position shown in Fig. 1 solid line with centrifugal force again.

During use, operator's left hand is pinched (common 100～a 200) neat lead, right hand thumb and forefinger are told a lead arbitrarily from left hand, the end of a thread is filled in tubaeform pilot hole 17, by transparent head, in the time of can seeing cutting edge that the end of a thread stretches out cutter head 19 to the length that needs peeling (generally stretching out about 5mm), touching cover clamp 13(design propelling size gently with facies digitales dorsales manus in the right hand or dorsal surface of index finger is 1.3mm), narrated as the front, the cutting edge of the cutter head 19 that is rotating promptly closes up in opposite directions, cut-out is scratched in 1/3～2/3 of wire external layer rubber cross section outer ring, pull outward with being about to lead, the rubber head is promptly broken and is taken off, and the blanking port below transparent guide cover 11 is discharged.

Running hours, all processes of above-mentioned action on average can be finished within 1 second.

Again because: it is wide that the back side of (1) cutter head 19 cutting edges is provided with 1.6mm, and the V-shaped line groove that 0.2mm is dark withstands the section of rubber head, guaranteed the rubber head before coming off necessarily with cutter head 19 rotation.(2) outer rim of rubber inwall and lead core has certain friction, so rubber withdraws from cutter rotation limit in front, and is just that lead core metal wire ply twist is tight.

As shown in Figure 1, when being pulled outward by the lead of peeling, the cutting edge of a pair of cutter head 19 gets one's teeth into lead rubber, and before the rubber head did not come off, cutter head 19 can not become flexible, and this has just guaranteed that the end of a thread rubber do not take off, and lead just can not pull.

General the most frequently used rubber lead, rubber external diameter between φ 1mm to φ 2.7mm, the total external diameter of core metal line between φ 0.3mm to φ 1.3mm, so, the distance of accurately regulating edge how according to the lead of different thicknesses?

As seen from Figure 1, when rotating the knob 2 of fine setting screw rod with hand, obviously can not axially advance and retreat in the screw rod two ends, thereby force fine setting drive block 1 to move, fine setting drive block 1 is because other has two guiding garden post location parallel with screw rod, guarantee that it can only parallelly move, driving fine setting fork 4 and then moves forward and backward, obviously, when the direction of fine setting fork 4, when promptly illustrating past moving right toward cutter head 19, its fork pin forces the knife rest 20 of 8 li of carriage guides to be drawn close to the center trace, otherwise then trace is left away laterally, and the maximum round trip amount of design displacement is ± 0.5mm * 2=± 1mm.

Gap length between cutter head 19 edges is determined by three size factors: in the middle of (1) cutting edge the V-arrangement cutting edge is arranged, two V-arrangement cutting edges are harmonious, and promptly are a rhombus, and the short diagonal of this rhombus is 0.35 * 2=0.7mm.Long-diagonal is 1.6mm.(2) cutter head 19 is around cutter head rotating shaft 18 rotating certain angle, when getting rid of outside the cutter head 19 to position shown in Fig. 1 solid line, blade gap radial dimension increases 0.8mm * 2=1.6mm, and when closing up to position shown in Fig. 1 double dot dash line, the gap radial dimension dwindles 0.8mm * 2=1.6mm.(3) distance of knife rest 20 is regulated by fine setting fork 4, changes between ± 0.5mm * 2=± 1mm again.

Like this, as Fig. 2, shown in Figure 3, be two kinds of operating states when minimum and maximum are transferred in the cutting edge gap of cutter head 19.

Shown in Figure 2, the cutting edge gap of cutter head 19 changes between 0.35mm * 2=0.7mm and 0.35mm * 2+0.8mm * 2=2.3mm.

Shown in Figure 3, cutter head 19 cutting edge gaps change between 0.35mm * 2+0.5mm * 2=1.7mm and 0.35mm * 2+0.5mm * 2+0.8mm * 2=3.3mm.

This has just guaranteed that the most frequently used rubber external diameter is φ 1mm to 2.7mm, and the total external diameter of core metal line is the usefulness that core is twisted with the fingers in the peeling of the rubber lead of φ 0.3mm to φ 1.3mm.

Regulate the suitable size in cutter head 19 edge gaps according to the lead thickness for the ease of the operator, the pointer of servo-actuated is equipped with in upper end at fine setting drive block 1, on shell 9, post with pointer corresponding, the graduation apparatus of indication lead core metal wire total outside dimension.0.3,0.5,0.7,1.0, a 1.3mm5 class can reference graduation apparatus is divided into:.

In order to guarantee that motor output shaft 5 is not subjected to axial tension or pressure, guarantee not move axially before and after knife rest 20 is, be provided with thin neck at the head of axle sleeve 6, thin neck is embedded in the hole, garden of axle sleeve pressing plate 7, and pulling force or pressure have just been born by axle sleeve pressing plate 7.

In order to guarantee that knife rest 20 and motor output shaft 5 rotate synchronously, rotating torque is by the square section of the end of motor output shaft 5 and the square section coupling transmission of the bottom, hole of axle sleeve 6.

For seeing clearly, the operator stretches out cutter head 19 cutting edges the end of a thread length partly, so, transparent guide cover 11, guiding garden bar 12, the loudspeaker oral area of tubaeform pilot hole 17, tubaeform pilot hole fixed head 14, the base portion of trim ring 15 all adopts transparent material to make.

In order to reduce operator's visual fatigue, the present invention takes two measures: the outer rim of (1) is tubaeform pilot hole 17 is coated with dark garden circle.(2) transparent guide cover 11 below join a 2～5W fluorescence small electric bulb light source.

Partly wear-resisting in order to guarantee that trim ring 15 and cutter head 19 frequently contact, reduce friction, reduce heating, so, its contact-making surface is designed to the garden arc.

In order to guarantee that the thickness wire head can both be by accurately stretching into behind the tubaeform pilot hole 17 in the middle of the cutting edge of cutter head 19, the small bore end of tubaeform pilot hole 17 is surrounded by four whippy, thin and smooth small pieces, its bore can change between φ 1.8mm to φ 2.7mm; the top ends internal orifice of flakelet has the garden arc to turn up; smooth to guarantee the lead turnover, " does not sting line "

It is the single-phase shaded-pole electrical micro-machine of the cheapness of (20 ± 5) W that motor adopts power, requires four utmost points, two utmost points (1400 rev/mins, 2800 rev/mins) second gear speed change or adopts electronic stepless speed regulation.When the processing lead is thicker, the wire stripping head is longer, and lead rubber inwall combine tight with heart yearn and friction is bigger, can adopt than the slow-speed of revolution, otherwise, adopt than rotating speed greatly.

When this machine is not worked, have the garden lid to screw on the head, the protection head is not damaged.

Fixing of complete machine, the same with little bench vice, the workbench edge is bitten in the bottom, is held out against by the M10 screw rod and stings the jail.

Implement the present invention, the factory with injection moulding, metalworking ability can both produce.

After cutter head 19 adopts T10-T13 quality carbon tool steel or high-speed steel mold pressing or line excision forming, making quenching-lonneal handles, meticulous sharpening, impose vacuum ion plating at last with titanium nitride, but 3 times of life-savings, to guarantee that a pair of cutter head can process more than the hundreds thousand of leads, cutter head can be equipped with at random as consumable accessory in addition.

Fixing of cutter head clamping plate 16 and knife rest, it is bonding to be equipped with powerful adhesive by quilting rivet.

The afterbody of guiding garden bar 12 and garden, axle sleeve 6 end column thick neck section, bonding on the available garden snare that matches.

Require wear-resisting position, axle sleeve 6, fine setting drive block 1, carriage guide 8, trim ring 15 can adopt the wear resistant nylon injection mo(u)lding.

Fine setting drive block 1 and the internal thread of finely tuning screw rod 2 couplings, and the guiding garden post parallel with screw rod of fine setting drive block 1 can embed injection moulding by metal insert.

This machine is produced, and the part required precision is higher slightly in addition, but does not have difficult especially, overcritical part.
