DESCRIPTION:
BRIEF SUMMARY
The invention relates to a machine for attaching connecting elements to cable ends by crimping the connecting element to the cable.
The goal of the invention is to improve on a machine of this type, in particular to simplify it considerably.
The solution to this problem according to the invention is provided by the teaching of the characterizing clause of claim 1.
Advantageous embodiments of the invention are listed in the subclaims.
On the other hand, thus far only one device for pressing (not shown) a "tip" onto the end of a wire or a stranded connector has been published (see German Pat. No. 32 05 413-A1).
It comprises specifically:
The stripping device is located in the gripping arrangement when the stranded conductor is inserted into the latter.
After the end of the stranded conductor has been stripped, the carriage body slides, causing the pressing device to move toward the gripping arrangement and, as a result of further sliding of the carriage body, onto the stripped free end of the stranded conductor, whereupon pressing takes place. Finally, the carriage body is pushed back, whereupon the ejector, with an ejector rod, pushes the end of the stranded conductor with the tip pressed in place, out of the crimping chamber and the centering chamber.
While in this known embodiment the feed of the "tips" to the centering arrangement and the crimping arrangement as well as the design of the stripping arrangement are left completely open, the following design is disclosed exclusively for the centering arrangement and the crimping arrangement (both in the claims and in the description of the figures): cross section for squeezing the "tips" by each segmental body forms a side wall of the crimping chamber, and which is perpendicular to the lengthwise axis of the segmental bodies, and conductor into the "tip" located in the crimping chamber comprises accordingly: straight prisms, in the insertion direction of the wire or stranded conductor, of each segmental body forms a lateral wall of the centering chamber, and perpendicular to the lengthwise axis of the segmental bodies and side of the wire or stranded conductor, comprises a frustroconical segment tapering from the insertion opening to the interior of the centering chamber, and a circularly cylindrical segment adjacent thereto, extending over the remaining length of the centering chamber, and virtue of its frustroconical segment, a reliable insertion of the end of the stranded conductor in the stripped state, even if individual strands of the stranded conductor project laterally from the lengthwise axis of the end of the stranded conductor.
In this connection, an automatic "tip mounting machine" for (exclusively) 1.5 mm.times.10 mm tips, DIN 46 218 on 1.5 mm NYAF wire with the following features has been disclosed (trade name: "Klemmfix 2001" made by the Weiszhar Co.):
Stripping arrangement:
Two knives and a stop, by which the depth of cut can be set precisely, so that the stranded conductor is not damaged during stripping:
Tip feeding arrangement:
By means of a "tip strip"(tip belt) wound on a magazine disk, automatic feed of lead tips to a feed funnel;
Pressing arrangement:
Four-edge pressing is provided by a toggle lever and constant spring pressure to produce a constant crimping result:
Motion control:
Drive with magnetic clutch and brake, as well as "hardened curves".
Disadvantages of this known state of the art include in particular: stripping, owing to the required manual labor (which would be equivalent to the "tedious threading of the lead tips" which is to be avoided), is left over as waste, dimensions of the tip belt magazine disk; stripped ends of the stranded conductor; the numerous segmental bodies and their mountings; and trouble-proneness of the entire device; and is relatively slow to respond; of the device for different tip dimensions; NYAF) and a very specific tip (1.5 mm.times.10 mm DIN 46 218), considerably limiting its use in operational practice; crimping arrangement, and therefore possible aging of the springs.
Moreover, numerous machi
