Description

The invention relates to a machine for crimping cable ends with ferrules or the like. Connection elements according to the preamble of claim 1.

The object of the invention is to further develop such a machine, in particular to simplify it considerably.

This object is achieved by the teaching according to the characterizing part of claim 1.

Advantageous embodiments of the invention are specified in the subclaims.

When moving the slide, the next following, currently stationary wire end sleeve, the plastic collar of which protrudes above the slide, reaches with its metallic tube piece into the elongated, narrower section of the keyhole-like first opening in the upper finger of the moved slide, so that at the end of the displacement, when the The opening in the web of the slide guide is aligned with the second opening in the lower finger of the slide, and cannot fall through simultaneously with the wire end sleeve already present in the opening of the web of the slide guide, but only when the slide is pushed back into the Opening falls (since the wire end sleeve previously there has failed), but hits the closed surface of the lower finger with the lower end of the metallic pipe section; however, another wire end sleeve can now move up (see also FIGS. 2 3, 2 4 with FIGS. 25, 26).

In contrast, only one device for pressing (not shown) "sleeves" onto the end of a wire or a strand has become known (cf. DE 32 05 413 - A1).

The stripping device is located when the wire is inserted into the gripping device.

After stripping the end of the stranded wire, the pressing device reaches the gripping device by moving the carriage body and further shifting the carriage body onto the stripped free stranded end, after which the pressing takes place. Finally, the carriage body is pushed back so that the ejector with an ejection rod presses the stranded end provided with the pressed-on sleeve out of the squeezing chamber and the centering chamber.

  • - wobei die Zentriereinrichtung insbesondere mit ihrem stumpfkegeligen Abschnitt ein sicheres Einführen des Litzenendes in abisoliertem Zustand auch dann sicherstellen soll, wenn einzelne Litzendrähte von der Längsachse des Litzenendes seitlich abstehen.

While in this known embodiment the supply of the "sleeves" to the centering device and to the squeezing device and the structure of the stripping device are exclusively the following structure is disclosed for the centering device and the squeezing device (both in the claims and in the description of the figures):

• - The movable, the "sleeve" receiving squeeze chamber can be reduced in cross-section to compress the "sleeve" by
  • - four segment bodies having the shape of straight prisms, the
    • are arranged around the square squeeze chamber such that a side face of each segment body forms a side wall of the squeeze chamber, and
    • - Are each slidably guided along a straight line in a cross-sectional plane perpendicular to the longitudinal axis of the segment bodies; and
• - The centering device for inserting the end of the wire or the strand into the "sleeve" located in the squeezing chamber accordingly has:
  • - In front of the squeezing chamber four segment bodies having the shape of straight prisms in the direction of insertion of the wire or the strand, the
    • - Are arranged around the centering chamber so that a side surface of each segment body forms a side wall of the centering chamber, and
    • - Are each guided along a straight line in a cross-sectional plane perpendicular to the longitudinal axis of the segment bodies, and
  • - The centering chamber in the closed position on the insertion side of the wire or the strand a blunt conical section which tapers from the insertion opening towards the interior of the centering chamber and an adjoining circular cylindrical section which extends over the remaining length of the centering chamber, and
  • - The centering device, in particular with its truncated cone section, should also ensure a secure insertion of the stranded end in the stripped state when individual stranded wires project laterally from the longitudinal axis of the stranded end.

• - Absioliereinrichtung:
  • zwei Messer und ein Anschlag, mit dem die Schnittiefe genau eingestellt werden soll, damit beim Abisolieren die Litze nicht beschädigt wird;
• - Hülsen-Zuführeinrichtung:
  • über ein auf einer Magazinscheibe aufgewickeltes "Hülsen-Band" (Hülsengurt) automatische Zufuhr der Aderendhülsen zu einem Einführtrichter;
• - Aufpresseinrichtung:
  • eine Vierkantverpressung soll durch einen Kniehebel und konstanten Federdruck ein konstantes Quetschergebnis erzielen;
• - Bewegungssteuerung:
  • Getriebe mit Magnetkupplung und -bremse sowie mit "gehärteten Kurven".

In this context, an "end-sleeve placement machine" for (exclusively) 1.5 mm x 10 mm end sleeve DIN 46 218 on 1.5 mm NYAF wire has become known with the following features (company name "Klemmfix 2001" from Weiszhar):

• - stripping device:
  • two knives and a stop with which the depth of cut should be set precisely so that the wire is not damaged when stripping;
• - Sleeve feed device:
  • via a "sleeve tape" (sleeve belt) wound on a magazine disc, the ferrules are automatically fed to an insertion funnel;
• - Press-on device:
  • a square crimp should achieve a constant squeezing result by means of a toggle lever and constant spring pressure;
• - motion control:
  • Gearbox with magnetic clutch and brake as well as with "hardened curves".

• - unvermeidliches aufwendiges Gurten der Aderendhülsen,
  • - was die dort angestrebte Zeiteinsparung durch das automatische Abisolieren erheblich in Frage stellt wegen der dort erforderlichen Handarbeit (die dem zu vermeidenden "mühseligen Einfädeln der Aderendhülse" in nichts nachstehen dürfte),
  • - ganz abgesehen von der zusätzlichen Beschaffung von Gurtmaterial, das zudem als Abfall übrig bleibt,
  • - schließlich auch die Lagerhaltung erschwert und
  • - wegen der beträchtlichen Abmessungen der Hülsengurt-Magazinscheibe die gesamte Vorrichtung beträchtlich sperriger macht;
• - gesonderte, aufwendige Zentriereinrichtung für ein sicheres Einführen des abisolierten Litzenendes;
• - aufwendiger, störanfälliger Aufbau der Quetscheinrichtung -insbesondere wegen der zahlreichen Segmentkörper und deren Lagerung;
• - gesonderter Auswerfer (der Quetscheinrichtung), der Aufwand und Störanfälligkeit der gesamten Vorrichtung erhöht;
• - nicht bestriebssichere und relativ langsam ansprechende Steuerung in Form der "gehärteten Kurven";
• - schwierige, allenfalls sehr begrenzte oder überhaupt unmögliche Einstellbarkeit der Vorrichtung auf unterschiedliche Hülsen-Abmessungen;
  so ist der "Klemmfix 2001" lediglich für einen ganz bestimmten Draht (1,5 mm NYAF) und eine ganz bestimmte Endhülse (1,5 mm x 10 mm DIN 46 218) vorgesehen, was einen Einsatz in der betrieblichen Praxis sehr einschränkt;
• - keine konstante Aufquetschqualität wegen des Kniehebel-Feder-Antriebs der Quetscheinrichtung und damit möglicher Alterung der Feder.

Disadvantages of this known prior art are in particular

• - unavoidable expensive strapping of the ferrules,
  • - Which considerably jeopardizes the time saved by automatic stripping because of the manual work required there (which should in no way be inferior to the "tedious threading of the ferrule" to be avoided),
  • - not to mention the additional procurement of belt material that also remains as waste,
  • - Finally, it also makes storage difficult and
  • - Because of the considerable dimensions of the sleeve belt magazine disc, the entire device is considerably bulky;
• - Separate, complex centering device for safe insertion of the stripped wire end;
• - Elaborate, fault-prone structure of the squeezing device - in particular because of the numerous segment bodies and their storage;
• - Separate ejector (the squeeze device), the effort and susceptibility to failure of the entire device increases;
• - Not reliable and relatively slow responsive control in the form of the "hardened curves";
• - Difficult, at most very limited or impossible to adjust the device to different sleeve dimensions;
  For example, the "Klemmfix 2001" is only intended for a very specific wire (1.5 mm NYAF) and a very specific end sleeve (1.5 mm x 10 mm DIN 46 218), which limits its use in operational practice;
• - No constant squeezing quality due to the toggle spring drive of the squeeze device and thus possible aging of the spring.

In addition, numerous machines for crimping cable wire ends with previously specially taped crimp contact elements, which therefore have to be fed in and processed in the form of a belt, have long been known (cf., for example, US Pat. No. 3,376,627).

It feeds the crimping / fitting device 100 and, according to FIG. 2 and 2 line outside of the housing 10 arranged wire end sleeve storage container 201 in the form of an oscillating conveyor (not shown in more detail), one end of the end sleeves A from this in the vertical axis direction one behind the other and with the metallic tube piece a receiving vertical end sleeve feed shaft 202, which is from above forth into the housing 10 between its front wall 11 and the front plate 31 of the swivel-slide frame 30, and a wire end sleeve separating device 203 which controls the wire end sleeve feed shaft 202 and which, when actuated, in each case a single wire end sleeve A of the crimping / fitting device 100 feeds.

- End sleeve separating device 203:

According to F i g. 2 1 - 2 9 it has a U-slide 204, which according to FIG. 29 has two fingers 205 and 206, which are spaced one above the other in the ferrule feed shaft 202, and is guided in a slide guide in the form of a slide housing 207, which has a guide recess 208 corresponding to its cross section. In a housing web 209 which extends over the length of the guide recess 208 and over which the slide 204 engages with its fingers 205 and 206, a bore 210 is delimited by the slide fingers 205 and 206 and is (somewhat) longer than the ferrule length which together with two tubes 211 and 212, one of which is inserted from above to the upper finger 205 and the other from below to the lower finger 206 in the valve housing 207, forms the ferrule feed shaft 202.

For additional guidance of the slide 204 in the slide housing 207 there are two uprights inserted into the slide housing 207 Bolt 213 are provided which are incorporated in the direction of movement of the slide 204 in the guide body 214 provided in the base body 214 of the slide 204. The slide 204 is held in an end position by two prestressed compression coil springs 216 supported on it and on the slide housing 207, which are penetrated by the stud bolts 213, which is limited by a stop plate 217 screwed to the slide housing 207.

The upper slide finger 205 has, according to FIG. 2 8, 2 9 a bore 218 corresponding to the light passage of the ferrule feed shaft 202 and a slot 219 extending from the stop plate 217 and slightly larger than the diameter of the metallic tube piece a of the ferrule A, both of which (218 and 219) expand towards the upper section of the ferrule feed shaft 202 formed by the tube 211 and together form a keyhole profile.

The lower slide finger 206 has, in particular according to FIG. 2 8, 2 9, on the other hand, only a bore 220 corresponding to the light passage of the ferrule feed shaft 202. The bore 218 in the upper finger 205 and the bore 220 in the lower finger 206 are offset from one another in such a way that in the end defined by the stop plate 217 Position of the slide 204 covers the bore 217 in the upper finger 205 with the feed shaft 202 and the bore 220 in the lower finger 206 is displaced from the area of the ferrule feed shaft 202.

As a result, a wire end sleeve A can form from the tube 211 inserted from above up to the upper slide finger 205 into the slide housing 207, which, as the upper section of the wire end sleeve feed shaft 202, forms a wire end sleeve magazine, in the section formed by the slide housing bore 210 of the wire end ferrule feed chute 202. The wire end sleeve which has moved upward from the stored wire end sleeve from the wire end sleeve magazine and which is embedded with a partial length of the metallic tube piece a on the plastic collar b of the stored wire end sleeve A, projects with the metallic tube piece a into the slide housing bore 210 (FIG. 2 5 , 2 6).

If the slide 204 is then moved against the force of the compression coil springs 216 from the end position delimited by the stop plate 217 to the other end position, the bore 220 in the lower slide finger 206 with the ferrule feed shaft 202 comes in and the bore 218 in the upper slider finger 205 out of register with the ferrule feed chute 202, the slot 219 extending from the bore 218 in the upper slider finger 205 crossing the ferrule feed shaft 202. As a result, the wire end sleeve stored in the slider housing bore 210 is released into the tube 212 forming the section of the wire end sleeve feed shaft 202 for loading the crimping / fitting device 100, and the next wire end sleeve protruding into the slider housing bore 210 with the metallic tube piece a is released access to the slide housing bore 210 is blocked by the upper slide finger 205.

The ferrule feed chute 202 is shown in FIG. 2 arranged so that it is positioned with its opening close to the ferrule receiving mouth 126 of the crimping / fitting device 100 with the pivoting-pushing frame 30 pivoted into the first end pivoting position and shifted into the first end pushing position (FIG. 1 1).

The actuation of the wire-end sleeve separating device 203 for loading the crimping / fitting device 100 with one wire end sleeve A each takes place on the front plate Te 31 of the swivel-push frame 30 attached bolts 227 (Fig. 2), which in the first end-swivel position from the second end-push position which controls the swivel-push frame 30 through a bore 221 in the stop plate 217 of the ferrule separating device 203 presses on the slide 204 of the ferrule separating device 203 (FIGS. 2 1, 2 2, 2 7).

The tube 211 forming an end sleeve feed shaft 202 as an upper section of the end sleeve feed shaft 202 has two receptacles 222 and 223 for one light barrier each, which monitor the minimum and maximum fill level of the end sleeve magazine and, depending on the magazine fill level, the wire end sleeve storage container 201 as a vibratory conveyor - or switch off.

B e t r i e b of the first embodiment of the machine:

It is based in particular on the Fig. 1, 2 and the operational flow chart according to F i g. 3 0, which shows the automatic operating sequence of the pneumatic pressure cylinders Zl - Z6 and the electric motor 62 caused by switches S1 - S10 from the start of the machine until it is ready to start again in connection with the successive operating sections Tl - T9 from the start of the machine to its ready to start again. Because of the details of the operating sections T1-T9, reference is expressly made to Fig. 30 to avoid repetition in the following text.

When the machine is ready to start again after the last operating step T9, the swivel-slide frame 30 is in the first end-swivel position and in the first end-push position, as a result of which the stripping device 50 is pivoted towards the cable core insertion 20 and with the cable core Guide funnel 64 is pushed close to the open cable tensioning device 22. The crimping / fitting device 100 is positioned (FIG. 11) with the ferrule pliers jaw 126 open at the mouth of the ferrule feed shaft 202 of the ferrule feed device 200, from which, in the final phase of the last operating step T9, it creates a ferrule A has recorded.

As soon as after the end of the operating step T4, the wire end sleeve A is applied to the stripped cable wire end KE, the pushing on of the wire end sleeve is carried out by initiating the operating step T5 by means of an end switch S5 which detects the first end push position of the swivel-push frame 30 on its rear plate 32 A triggered on the stripped cable core end KE by the squeeze pressure cylinder Z6.

As soon as the pressure in the squeeze pressure cylinder Z6 has reached the value required for squeezing the metallic tube piece a of the wire end sleeve A through the squeeze jaws 102, 103, the reversal control of the pressure cylinders Z5 and Z6 is triggered by a pressure-controlled switch S6 which detects it and thus releases the crimped-on ferrule from the ferrule pliers 101 in the crimping / fitting device 100.

After the end of the operating step T6, to initiate the operating step T7, the control of the swivel-push frame 30 is activated by an end switch S7 which detects the release of the crimped-on wire end sleeve from the clamping in the crimping / fitting device 100 on the wire end sleeve clamping / return pressure cylinder Z5 in the second end thrust position by the thrust pressure cylinder Z3 and by actuating the end switches S3 or S8, the opening of the cable core tensioning device 22 to be detected by a switch S8 (e.g. a light barrier) (FIG. l) complete pulling out of the fitted cable wire end KE is triggered by the cable wire tensioning pressure cylinder Zl, which actuates an end switch S10 (FIG. 1).

The end switch S3 which detects the second end-push position of the swivel-push frame 30 then triggers the piston retraction of the swivel pressure cylinder Z4 and thus swivels the swivel-push frame 30 back into the first end-swivel position.

Finally, after the end of the operating step T8 to initiate the operating step T9, an end switch S9 which detects the first end pivoting position of the swivel-push frame 30 triggers the piston extension of the push-pressure cylinder Z3, which pushes the swivel-push frame 30 into the moves the first end of the push position back so that the machine is ready for a new start.
