The Y type copper cash feed mechanism that is applied to metal zip fastener forming machine that the utility model embodiment provides, it is a matching component of metal zip fastener forming machine, the contour structures of showing book discharging mechanism 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 are made displaying by Fig. 1:
A on board main shaft 10, B, C, D, five cams of E drive each mechanism by corresponding parts respectively, 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 whole actions of feeding, cut-out, moulding, implantation strap and the slide fastener tethered sliding of a copper tooth of slide fastener.
The front and back running roller 22,23 of cam A by cross sliding clock 21 drives cross sliding clocks 21 to do, with respect to the seesawing of support, for shearing the cut-out counterdie 27 of copper cash, to be located in cross sliding clock 21 front positions; Cut-out counterdie 27 has the die cavity K2 with Y type copper section form fit, and its entrance band gradient is copper cash guiding; 26 of patrixes of cut-out are positioned at the below of the slide 33 of punching mechanism 30; When spindle cam A drives cross sliding clock 21, end and enter in the time of inactive state to advancing, cam D drives this mechanism to complete Y type copper cash fixed length up and sends to; After feeding finishes, cam A drives cross sliding clock 21 to retreat, cut off relatively moving of upper and lower mould 26,27 and cut off copper cash, cut fixed length copper cash in the form of sheets inlay card on cutting off in model cavity.In cross sliding clock 21 fallback procedures, after a pair of 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 cylindricals coordinate traction to implant copper tooth zipper cloth belt with pinch roller 43 up moves the distance of a fixed length; Along with cross sliding clock 21 has retreated and entered inactive state, the copper sheet of being cut is sitting at the top of stamping cavity die 25 die cavities, and cam B drives punching mechanism, makes punching press punch 24 complete the backward upper reset of Y type copper sheet head shaping downwards; Cam A drives cross sliding clock 21 to advance, the a pair of finishing die 28 of extrusion forming mechanism 20 is subject to the restriction of finishing die block 29 on holder guiding and inwardly closes up in cross sliding clock advances process, and the die cavity side of finishing die 28 acts on the relevant position that two shanks of Y type copper sheet make copper sheet be shaped and implant zipper cloth belt simultaneously.
Complete after above-mentioned action, cross sliding clock 21 enters the inactive state of advancing and ending.This mechanism starts action: main shaft 10 band moving cam D drive push-rod assembly 59 by running roller 59b, ratchet 59a on push rod promotes feeding ratchet 52b and rotates a tooth, the power input shaft 52 of Shi Ben mechanism rotates the angle of a standard, thereby completes the feeding of a Y type copper cash fixed length size.Cross sliding clock 21 starts to retreat immediately.
In above-mentioned whole process, the cam E on main shaft is all the time near the running roller 23 on cross sliding clock 20, and coordinates with cam A and running roller 22, guarantees the reliability of cross sliding clock 20 reciprocating actions.
Around above-mentioned copper cash feeding process, shown in Fig. 3, set forth the specific implementation process of this mechanism below.
One end of the power input shaft 52 of mechanism is feeding ratchet 52b fixedly, and the frustum on ratchet coordinates with damping unit 58; The gear 52a of the other end meshes well with the gear of active feed wheel 53a.Initiatively feed wheel 53 is positioned on Connection Block 51 by mandrel 53b, and can on mandrel 53b, rotate; Be arranged on the fork mandrel 54d constraint fork 54c of Connection Block 51, but make fork 54c rotate around it, make to be arranged on that driven pinch roller 54 on fork 54c can contact by copper cash with active feed wheel 53 or separated.
From Fig. 4, show, the center line of the groove that the center line of the 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.
Copper cash imports through bootstrap block 55 die cavities of mechanism below, between active feed wheel 53 and driven pinch roller 54, pass through, 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 basic identical, namely similar and slightly large to the cross sectional shape of Y type copper cash with the cavity shape of cutting off counterdie 27; When cross sliding clock 21 is when copper cash is sent position to, between bootstrap block 55 die cavities, cut-out counterdie 27 die cavities and active feed wheel 53 and driven pinch roller 54, the projection of the cross section three of copper cash on horizontal plane overlaps.Because copper cash is subject to the constrained of X, Y, tri-directions of Z in each die cavity, guaranteed that copper cash remains correct state when organisation operations, can not break away from initiatively feed wheel 53 and driven pinch roller 54 and occur other state.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 and copper cash and initiatively feed wheel 53 is separated and pass through smoothly copper cash.The distance moving in view of driven pinch roller 54 exceeds far away the whole depth of gear 54a, and the gear 54a of driven pinch roller 54 and initiatively the gear 53a of feed wheel 53 remain engagement, move accurate while again exerting pressure.Meanwhile, due to the porch 55c of bootstrap block 55 smooth transition with little gradient, even if the copper cash being imported into is distortion slightly, directed 55 guiding when importing and after forcing to correct by its die cavity.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.Thereby the damage of effectively having avoided mechanism and other relevant spare and accessory parts to cause because of the abnormality because of copper cash.
According to the operating principle of this mechanism, during copper cash feeding, initiatively the centerline of feed wheel 53 and driven pinch roller 54 is in same level, and when initiatively feed wheel 53 rotates, fork 54c drives driven pinch roller 54 to exert pressure; Shut down while importing copper cash, fork 54c drives driven pinch roller 54 to discharge separated with copper cash.Exert pressure releasing device 56 structures as shown in Figure 6: slide block 56a is positioned at the below of Connection Block 51; and led 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 laminating and force fork 54c to drive driven pinch roller 54 to apply pressure to copper cash, the size of pressure is by regulating the screw thread 56e of depression bar 56b to obtain.During this time, slide block 56a moves to end positions, the end face 56h of slide block 56 be connected the reserved certain distance of seat surface 51b, the pressure that guarantees spring 56c is all applied on the position that driven pinch roller 54 contacts with copper cash; After the quilt of the position of slide block 56a, move, rectangular opening face 56f position changes, and disappears with fork lower end side plane 54d pressure, and 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 show structure and the course of action that in the releasing device 56 of exerting pressure, slide block 56a moves forward and backward: eccentric briquetting 57a is positioned Connection Block 51 belows rotatable, when the handle 57b of eccentric briquetting 57a pulls to upwards time, the application point radius of eccentric briquetting 57a increases, and after slide block side boss 56g pressurized makes slide block 56a, moves; When going to slide block boss 56g, the face 57f of eccentric briquetting engages 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 when 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 in pressurized state, and eccentric briquetting 57a does not affect the work of driven pinch roller 54 in free state.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 control of device seem light and handy convenient.
Because mechanism adopts ratchet intermittently-driving form, when ratchet 52b is positively driven, from the thrust of ratchet 59a moment, likely make ratchet 52b have inertia and leading; On the other hand, during ratchet 59a recession, the pressure of back-moving spring likely causes ratchet to lag behind.Consequently caused the unstable of the amount of feeding.In ，Ben mechanism, be provided with damping holding device 58 as shown in Figure 9 for this reason:
On power input shaft 52, one end of fixing ratchet 52b is truncated cone shape, matches with the internal taper hole of damping block 58a; Taper hole inwall is inlayed the damping material 58b of high-quality; Damping block 58a profile is subject to bearing 58d guiding constraint, can only take ratchet 52b axis as micro-the moving axially of benchmark do; Damping block 58a under equally distributed spring 58c effect, the conical surface tight connecting of its conical surface and ratchet 52b.Utilize the screw on bearing 58d to adjust pressing plate 58e, can carry out the adjusting of frictional force size, thereby make device reach optimum state.Effectively prevent the lead and lag of ratchet 52b, guaranteed the accurate stable of the amount of feeding.Perfect structure action that main is, Ω type brake hoop clamping tension in the damping unit of having avoided generally using at present and the disadvantage that causes ratchet 52b or ratchet 59a to burst apart and damage.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the utility model.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
