Description
Technical field
The present invention relates to metal zip fastener forming machine field, exactly refer to a kind of Y type copper cash feed mechanism being applied to metal zip fastener forming machine.
Background technology
At present, just similar slide fastener shaping apparatus in the industry, its operating principle is consistent substantially: the action of cooperation between mutual by each mechanism for implementing of each actuated by cams on board main shaft, comprise after main shaft retreated the cut-out of Y type copper cash fixed length by cam driven cross sliding clock, continue in fallback procedures, main shaft drives strap mechanism traction zipper cloth belt to advance a station distance; Cross sliding clock retreats to time static, and the copper tooth sheet stock cut off is located; Main shaft is ordered about and is pressurizeed by punching mechanism, makes punching press punch and matrix coordinate and makes copper tooth sheet stock head formation; Cross sliding clock is in ensuing advance process, and shaping mechanism work is exerted pressure and the leg of copper tooth sheet stock, makes it be shaped and implants zipper cloth belt; Cross sliding clock advances in the quiescent time of end, and spindle cam, by push-rod assembly, drives feed mechanism Y type copper cash to be sent forward to the distance of one section of fixed length; Along with the retrogressing of cross sliding clock, shearing patrix relative motion fixing on the shearing counterdie on slide block and punching mechanism, the copper cash sending fixed length to cuts off, and forms copper tooth sheet stock and delivers to above molding concave die and locate.Above-mentioned explanation be board running one-period action relationships.And feed mechanism dynamic be exactly one of them important step.
The feed mechanism of the Y type metal zip fastener forming machine in current industry is all adopt same form, and its principle, structure, action, feature are all substantially identical:
The fixed angle that the ratchet that spindle cam orders about feed mechanism by push-rod assembly drives power input shaft to make interval rotates.The gear of power input shaft and two gears meshing initiatively on feed wheels; Two driven pinch rollers are bearing on V-arrangement three bracing strut of running roller support unit, V-arrangement three bracing strut is pushed by pressing device, realize two driven pinch rollers to Y type copper cash and two initiatively feed wheels exert pressure simultaneously, the gears meshing of the gear on period two driven pinch rollers and two active feed wheels; Driven pinch roller cylindrical is with groove and active feed wheel cylindrical flanged pin.Under the environment that above-mentioned condition possesses, mechanism for implementing feeding feeding; Coordinated by the action of release and contact device and the multiple part of pressing device, control two driven pinch rollers and two active feed wheel positions.Push copper cash feeding during contact, during release, manually guide feeding copper cash.Adopt Ω type braking damping unit, the operating advanced and reversal of anti-locking mechanism, does the adjustment of resistance with adjusting bolt.
In the long use procedure of machine for zipper, find that above-mentioned feeding structure exists many places deficiency:
1, when board shuts down, when again importing copper cash toward mechanism, release and contact device are pulled to release conditions, and V-arrangement three bracing strut is in one quick condition freely together with two driven pinch rollers.Under normal conditions, V-arrangement three bracing strut should be on symmetrical position for two active feed wheels, now forms equal gap between driven pinch roller with active feed wheel, and imports copper cash smoothly.For above-mentioned free state, suppose supporting mandrel's invariant position, initiatively feed wheel is asymmetric for two for V-arrangement three bracing strut, and namely a driven pinch roller contacts with active feed wheel, causes another driven pinch roller to double with active feed wheel gap.And two-wheeled is by meshed transmission gear, centre-to-centre spacing crosses the gear that the gear of driven pinch roller may well be caused to depart from initiatively feed wheel completely, or makes the tip portion of two gears to top, and V-arrangement three bracing strut can not enter normal position and exert pressure, and feeding quality is affected.Be operated to again after needing again to discharge and meet the requirements.
2, under the release in mechanism and contact device are in board, main body base groove is by inner position, installation and maintenance and inconvenient operation; With in timer release with two lever parts contacted because fulcrum and force are apart from undesirable, easily cause the radial constraint of this part and rotary core shaft to locate failure mode.
3, damping is undesirable, adjustment difficulty.In view of damping device main body is Ω type.When damping material along with board long time running is worn, damping device and ratchet matching part contact area reduce, and cause frictional force reduce and directly affect the precision that copper cash sends fixed length to; In fact damping device cross-sectional area is excessive, the elasticity of spring cannot make its distortion realize compensating, even if screw in adjustment by force with bolt, damping device inner circle cylindricity is changed, while damping is deteriorated, excessive push-rod assembly or the ratchet parts of tooth of causing of the clamping force of damping device is damaged because of overload.
4, structure is loaded down with trivial details, and action is complicated, and part processing precision requires high, and the cost causing part to be processed increases.

The Y type copper cash feed mechanism of what the embodiment of the present invention provided be applied to metal zip fastener forming machine, it is a matching component of metal zip fastener forming machine, the contour structures of mechanism is shown by Fig. 2, the power of mechanism is from board main shaft 10, and the principal organ of slide fastener shaping apparatus and associated components thereof and mutual alignment relation then make displaying by Fig. 1:
A, B, C, D, E on board main shaft 10 five cams drive each mechanism respectively by corresponding parts, and according to five specific shapes of cam and phase place, make corresponding mechanism cooperatively interact, in main shaft 10 rotates a circle process, accurately complete the feeding of a copper tooth of slide fastener, cut-out, shaping, whole actions of implanting strap and slide fastener tethered sliding.
Cam A drives cross sliding clock 21 to do seesawing relative to support by the front and back running roller 22,23 on cross sliding clock 21, and the cut-out counterdie 27 for shearing copper cash is located in cross sliding clock 21 front position; Cut off counterdie 27 and have the die cavity K2 with Y type copper section form fit, its entrance band gradient is copper cash guiding; Cut off the below that patrix 26 is positioned at the slide 33 of punching mechanism 30; Drive cross sliding clock 21 to end to advance as spindle cam A and enter in the time of inactive state, cam D drives mechanism to complete Y type copper cash fixed length up and sends to; After feeding terminates, cam A drives cross sliding clock 21 to retreat, and cuts off the relative movement of upper and lower mould 26,27 and cuts off copper cash, cut-off fixed length copper cash in the form of sheets inlay card in cut-out in model cavity.In cross sliding clock 21 fallback procedures, after a pair finishing die 28 of shaping mechanism 20 opens, cam C on main shaft 10 drives the running roller 41 of strap mechanism 40, make drawstring ratchet 42 rotate a tooth, ratchet 42 cylindrical coordinates the distance of drawing the zipper cloth belt up mobile fixed length having implanted copper tooth with pinch roller 43; Retreated along with cross sliding clock 21 and entered inactive state, being sitting at the top of stamping cavity die 25 die cavity by the copper sheet cut, cam B drives punching mechanism, makes punching press punch 24 complete the backward upper reset of Y type copper sheet head formation downwards; Cam A drives cross sliding clock 21 to advance, a pair finishing die 28 of extrusion forming mechanism 20 is subject to the restriction of finishing die block 29 on holder and guides and inwardly close up in cross sliding clock advance process, and two legs that the die cavity side of finishing die 28 acts on Y type copper sheet simultaneously make copper sheet be shaped and implant the relevant position of zipper cloth belt.
After completing above-mentioned action, cross sliding clock 21 enters the inactive state of advancing and ending.Mechanism starts action: main shaft 10 is with moving cam D to drive push-rod assembly 59 by running roller 59b, ratchet 59a on push rod promotes feeding ratchet 52b and rotates a tooth, make the power input shaft 52 of mechanism rotate the angle of a standard, thus complete the feeding of a Y type copper cash long dimension.Cross sliding clock 21 starts to retreat immediately.
In above-mentioned whole process, the cam E on main shaft all the time near the running roller 23 on cross sliding clock 20, and coordinates with cam A and running roller 22, ensures the reliability of cross sliding clock 20 reciprocating action.
Below around above-mentioned copper cash feeding process, shown in composition graphs 3, set forth the specific implementation process of mechanism.
Feeding ratchet 52b is fixed in one end of the power input shaft 52 of mechanism, and the frustum on ratchet coordinates with damping unit 58; The gear 52a of the other end engages well with the gear of active feed wheel 53a.Initiatively feed wheel 53 is positioned on Connection Block 51 by mandrel 53b, and can rotate on mandrel 53b; The fork mandrel 54d being arranged on Connection Block 51 retrains fork 54c, but makes fork 54c rotate around it, and making to be arranged on driven pinch roller 54 on fork 54c can be contacted by copper cash with active feed wheel 53 or be separated.
From Fig. 4 display, the center line of the groove that the center line of flange that initiatively feed wheel 53 contacts with Y type copper cash contacts with Y type copper cash with driven pinch roller 54 overlaps on a vertical plane.
Bootstrap block 55 die cavity of copper cash below mechanism imports, pass through between active feed wheel 53 and driven pinch roller 54, enter again and cut off counterdie 27, as shown in Figure 5, bootstrap block die cavity importing place 55c is with smooth gradient, bootstrap block 55 is with to cut off the cavity shape of counterdie 27 substantially identical, namely similar to the cross sectional shape of Y type copper cash and slightly large; When cross sliding clock 21 is in copper cash feeding position, bootstrap block 55 die cavity, cut-out counterdie 27 die cavity and the initiatively cross section three of copper cash projection coincidence in the horizontal plane between feed wheel 53 and driven pinch roller 54.Because copper cash is subject to the constraint restriction in X, Y, Z tri-directions in each die cavity, ensure that copper cash remains correct state when organisation operations, initiatively feed wheel 53 and driven pinch roller 54 and occur other state can not be broken away from.The action that in mechanism, fork 54c drives driven pinch roller 54 to discharge is directly reliable, only need make the amplitude of oscillation very among a small circle, is enough to make driven pinch roller 54 be separated with copper cash and active feed wheel 53 and pass through copper cash smoothly.Distance in view of the movement of driven pinch roller 54 exceeds far away the whole depth of gear 54a, and the gear 54a of driven the pinch roller 54 and gear 53a of active feed wheel 53 remains engagement, and when again exerting pressure, action is accurate.Meanwhile, due to porch 55c the smoothly transitting with little gradient of bootstrap block 55, even if the copper cash be imported into is in distortion slightly, guide for directed piece 55 when importing and pressure passes through its die cavity after correcting.Moreover suppose that local anomaly appears in copper cash, as tubercle, burr, shape exceed standard or the phenomenon such as excessive distortion, copper cash is subject to the restriction of bootstrap block 55 cavity shape and cannot passes through.Even if initiatively feed wheel 53 is rotated further, the feeding of copper cash is terminated equally.Thus efficiently avoid mechanism and the damage of other relevant spare and accessory parts because causing because of the abnormality of copper cash.
According to the operating principle of mechanism, during copper cash feeding, initiatively the centerline of feed wheel 53 and driven pinch roller 54 is in same level, and while initiatively feed wheel 53 rotates, fork 54c drives driven pinch roller 54 to exert pressure; When shutting down importing copper cash, fork 54c drives driven pinch roller 54 to discharge with copper cash and is separated.Exert pressure releasing device 56 structure as shown in Figure 6: slide block 56a is positioned at the below of Connection Block 51; and lead by Connection Block 51 and cover plate 51a; spring 56c in the rectangular opening of slide block 56a is subject to the restriction of thread 56b on Connection Block 51 and back-up ring 56d position and compresses, and the pressure of spring 56c forces slide block 56a toward initiatively feed wheel direction 53 is close; The side 56f of slide block rectangular opening and fork 54c lower flat 54e fits and forces fork 54c to drive driven pinch roller 54 to apply pressure to copper cash, and the size of pressure obtains by regulating the screw thread 56e of depression bar 56b.Period, slide block 56a moves to end positions, the end face 56h of slide block 56 be connected seat surface 51b and reserve certain distance, ensure that the pressure of spring 56c is all applied on the position that driven pinch roller 54 contacts with copper cash; When slide block 56a position by after move, 56f position, rectangular opening face change, with fork lower end side plane 54d distress resolves, the light-duty back-moving spring 54f on fork 54c makes fork 54c leave copper cash together with driven pinch roller 54.
Fig. 7 and Fig. 8 shows the structure and course of action that in releasing device 56 of exerting pressure, slide block 56a is movable: eccentric briquetting 57a is positioned below Connection Block 51 also rotatable, when the handle 57b of eccentric briquetting 57a pulls to time upwards, the application point radius of eccentric briquetting 57a increases, and moves after slide block side boss 56g pressurized makes slide block 56a; Engage with slide block boss 56g when the face 57f of eccentric briquetting goes to, slide block self-locking under the effect of spring 56c.Now position is fixed, and fork 54c and driven pinch roller 54 discharge; When the handle 57b of eccentric briquetting 57a pulls to time downward, the face 57e of eccentric briquetting is relative with slide block boss 56g and keep certain space, spring 56c pressure makes fork 54c and driven pinch roller 54 be in pressurized state, and eccentric briquetting 57a is then in free state and does not affect the work of driven pinch roller 54.This outdoor handle 57b is enough for the distance proportion of application point for eccentric briquetting mandrel 57c and mandrel, and the increase of moment makes the operation of device control to seem light and handy convenient.
Because mechanism adopts ratchet intermittently-driving form, when ratchet 52b is positively driven, the thrust from ratchet 59a moment likely makes ratchet 52b there is inertia and advanced; On the other hand, when ratchet 59a drops back, the pressure of back-moving spring likely causes ratchet delayed.Consequently cause the instability of the amount of feeding.For this reason, damping holding device 58 is as shown in Figure 9 provided with in mechanism:
One end of ratchet 52b fixing on power input shaft 52 is truncated cone shape, matches with the internal taper hole of damping block 58a; Taper hole inwall inlays the damping material 58b of high-quality; Damping block 58a profile, can only with ratchet 52b axis for benchmark does moving axially of trace by bearing 58d guiding constraint; Damping block 58a under equally distributed spring 58c effect, the conical surface tight connecting of its conical surface and ratchet 52b.Utilize the screw adjustment pressing plate 58e on bearing 58d, the adjustment of frictional force size can be carried out, thus make device reach optimum state.Effectively prevent the lead and lag of ratchet 52b, ensure that the accurate stable of the amount of feeding.More importantly perfect structure action, avoids Ω type brake hoop clamping tension in the damping unit generally used at present and causes ratchet 52b or ratchet 59a to burst apart the disadvantage damaged.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
