Description

25th

The invention relates to a machine for squeezing jeladerenden Ka jeladerenden with ferrules or the like. Connection elements according to the preamble of claim 1.

Such a known machine (US 40 64 624) can only have specific dimensioned connection elements process, which must also be strapped. Of the connection elements are namely the metallic Contact sleeves and the expanded plastic collar captured by jaws, but together by means of a single screw are attached to a drive member, so that a relative adjustment of clamping and crushing is impossible

The object of the invention, on the other hand, is to process unbelted belts in such a machine Connection elements with any relative dimensions of contact sleeve and remaining connection element part, especially plastic collars.

The inventive solution to the problem is carried out by the teaching according to the characterizing part of Claim 1.

Only a crimping tool with pliers-like is still known (cf. DE-AS 26 14 577) arranged press jaws.

Advantageous refinements of the invention are specified in the subclaims.

In contrast, so far only a device for pressing (not shown) "sleeves" onto the End of a wire or stranded wire became known (see. DE 32 05 413-Al).

It has in detail:

- a gripping device,

- which should hold the strand immovable,

- a press-on device

- a squeezing device with squeezing chamber,

- an upstream centering device with centering chamber and

- an ejector,

- a stripping device and

- a "sled body" that

- is movable in two mutually perpendicular movements and

- Carries the press-on device and the stripping device.

The stripping device is located when the strand is plugged into the gripping device.

After the end of the strand has been stripped, the press-on device is moved by moving the slide body to the gripping device and by moving the slide body further onto the stripped free strand end, after which the pressing takes place. Finally, the slide body is pushed back so that the ejector the end of the strand, provided with the pressed-on sleeve, from the squeezing chamber with an ejector rod and pushes out the centering chamber.

While in this known design, the supply of the "sleeves" to the centering device is left completely open and for the squeezing device as well as the structure of the stripping device, is for the centering device and the squeezing device exclusively discloses the following structure (both in claims as well as in the description of the figures):

- the movable, the "sleeve" receiving squeeze chamber is in its cross-section to be compressed the »sleeve« can be reduced in size

- Four segment bodies having the shape of straight prisms, the

- Are arranged around the square pinch chamber around that one side surface of each segment body forms a side wall of the squeeze chamber, and

- each in a transverse plane perpendicular to the longitudinal axis of the segment body are guided displaceably along a straight line; and

The centering device for inserting the end of the wire or strand into the pinch chamber The "sleeve" located has accordingly:

- In front of the squeeze chamber, four segment bodies in the form of straight prisms in the direction of insertion of the wire or strand that

- Are arranged around the centering chamber that one side surface of a each segment body forms a side wall of the centering chamber, and

- Can be displaced along a straight line in each case in a cross-sectional plane perpendicular to the longitudinal axis of the segment body are performed, and

- The centering chamber in the closed position on the insertion side of the wire or the Braid a frustoconical, stretching from the insertion opening to the inside of the centering chamber tapering section and an adjoining section, extending over the rest of the way Having the length of the centering chamber extending circular cylindrical portion, and

- The centering device, in particular with its frusto-conical section, a safe one Insertion of the strand end in the stripped state should also ensure if individual stranded wires protrude laterally from the longitudinal axis of the stranded ends.

In this context there is also an »end sleeve fitting machine« for (exclusively) 1.5 mm χ 10 mm end sleeve DIN 46 218 on 1.5 mm NYAF wire with the following Features become known (company publication »Klemmfix 2001« from Weiszhar):

- Stripping device:

two knives and a stop with which the cutting depth is to be set precisely, so when stripping the strand is not damaged;

- Tube feeding device:

Automatic feed via a »sleeve tape« (sleeve belt) wound on a magazine disc the ferrules to an insertion funnel;

- Pressing device: a square pressing should be done by a toggle lever and constant spring pressure achieve a constant squeezing result;

- motion control:

Gearbox with magnetic clutch and brake as well as with "hardened curves".

The disadvantages of this known prior art: appear in particular:

25th

- unavoidable laborious strapping of the wire end sleeves,

- which significantly jeopardizes the time savings sought there through automatic stripping poses because of the manual labor required there (which is to be avoided »laborious Threading the wire end ferrule «should be in no way inferior),

- Not to mention the additional procurement of belt material, which is also waste remains

- finally also complicates the storage and

- Because of the considerable dimensions of the sleeve belt magazine disc, the entire device makes it considerably bulkier;

- Separate, complex centering device for a safe insertion of the stripped strand end;

- The structure of the squeezing device, in particular because of the numerous segment bodies and their Storage;

- separate ejector (the squeezing device);

- Control in the form of "hardened curves";

- Difficult, at most very limited adjustability of the device to different sleeve dimensions;

so the »Klemmfix 2001« is only for one very specific wire (1.5 mm NYAF) and one whole certain end sleeves (1.5 mm χ 10 mm DIN 46 218) are provided, which means that they can be used in operational applications Very limited practice:

- No constant squeezing quality due to the toggle-spring drive of the squeezing device and thus possible aging of the spring.

60

In addition, there are numerous machines for the squeezing-on of cable wire ends with previously special taped crimp contact elements, which are therefore expensive must be supplied and processed in belt form, known for a long time (cf. z. B. US-PS 76 627).
