Clamping apparatus for a crimping machine and method for producing a crimped connection with a crimping machine and the clamping apparatus according to the invention
A clamping apparatus, for a crimping machine ( 1 ), which comprises a crimping tool head ( 2 ) with an end wall ( 9 ), in a cable feed direction, a crimping tool base body ( 3 ) with an anvil ( 4 ) and a front knife ( 21 ), an insulation stripping apparatus ( 5 ); a contact element feed apparatus ( 6 ); and a coupling part ( 7 ) for coupling the crimping machine ( 1 ) to the crimping tool head ( 2 ). The clamping apparatus ( 10 ) clamping the electric cable ( 8 ) to be processed both during the insulation stripping and crimping processes. The clamping apparatus ( 10 ) is connected to the crimping tool head ( 2 ) via its end wall ( 9 ) and is movable vertically with the crimping tool head ( 2 ). At least one of the clamping apparatus ( 10 ) and the crimping tool head ( 2 ) is arranged centrally in a longitudinal direction of the cable path ( 8 ′) above the anvil ( 4 ) and the front knife ( 21 ).
1. A crimping machine, comprising:
a crimping tool head having an end face arranged transverse to a cable path, along which a cable to be crimped is fed in operation of the crimping machine;
a crimping tool base body having an anvil and a front knife,
an insulation stripping apparatus;
a contact element feed apparatus; and
a coupling part for coupling the crimping machine to the crimping tool head;
a clamping apparatus being connected to the crimping tool head via said end face wherein said clamping apparatus can be moved vertically with the crimping tool head, and wherein at least one of the clamping apparatus and the crimping tool head is arranged centrally in a longitudinal direction of the cable path above the anvil and the front knife wherein the clamping apparatus is designed to clamp the electric cable to be processed, both during an insulation stripping process performed by the insulation stripping apparatus and during a crimping process performed by the crimping tool head.
2. The crimping machine according to patent claim 1 , wherein the clamping apparatus is connected rigidly, preferably by means of a detachable connection, for example a screw, plug and/or clamping connection, to the crimping tool head.
3. The crimping machine according to claim 1 , where in the clamping apparatus has at least one upper clamping jaw and one lower clamping jaw which are moveable in opposite directions to one another in the vertical direction via one or more spring elements, for example pressure springs ( 13 ).
4. The crimping machine according to claims 1 , wherein the clamping jaws are arranged so as to be moveable in a cuboid housing open at least at the bottom, and the housing has, on its top two slots arranged parallel to one another and perpendicularly to the longitudinal direction of the cable path.
5. The crimping machine according to claim 1 , wherein the upper clamping jaw comprises a clamping jaw arm and a clamping jaw finger bent at right angles in the direction of the lower clamping jaw, the bottom of the finger clamping the cable during the entire processing.
6. The crimping machine according to claim 1 , wherein the lower clamping jaw comprises a substantially cuboid clamping jaw arm having a lower edge, an arm extension, which is approximately half as wide as the clamping jaw arm and which corresponds approximately to the width of the clamping jaw arm, and a clamping jaw finger bent at right angles from the arm extension in the direction of the upper clamping jaw.
7. The crimping machine according to claim 1 , wherein the pressure springs are fixed in a cavity of the clamping jaw arm above the lower edge.
8. The crimping machine according to claim 1 , wherein at least one pin each of different lengths is attached to each clamping jaw in the region of the clamping jaw arms, the longer pin of the lower clamping jaw passing through the first slot and the shorter pin of the upper clamping jaw passing through the second slot, and the pins forming the end stops for the open position of the clamping jaws.
