Pivoting pliers jaw in a design comprising plates and crimping pliers comprising a pivoting pliers jaw
A pivoting pliers jaw ( 18 ) having a design including plates for manually actuated crimping pliers ( 1 ). The pivoting pliers jaw ( 18 ) which includes a supporting plate ( 23 ) at which on both sides pliers jaw plates ( 25 ) are held. The pliers jaw plates ( 25 ) form an accommodation for a die insert or support the accommodation. According to the invention the pivoting pliers jaw ( 18 ) is L-shaped. Bolts ( 27, 28 ) for mounting the pliers jaw plates ( 25 ) to the supporting plate ( 23 ) are arranged in a way such that a connecting axis of the longitudinal axes of the bolts ( 27, 28 ) have an orientation approximately perpendicular to a supporting plane ( 36 ) for the effective crimping force.
1. A pivoting pliers jaw comprising
a) a supporting plate and
b) a pliers jaw plate, which
ba) forms or supports at least one accommodation for a die insert,
bb) defines a supporting plane of the at least one accommodation for supporting a crimping force biasing the die insert,
bc) is arranged with an overlap on one side of the supporting plate and
bd) is fixed in a region of the overlap by a first bolt and a second bolt at the supporting plate,
c) an angle between
a connecting axis of longitudinal axes of the first bolt and the second bolt and
the supporting plane in a pliers head plane being 90°±30°,
d) the pliers jaw plate comprising a mounting leg and a pliers jaw leg, the mounting leg and the pliers jaw leg being arranged in an L-shape and
e) the first bolt extending through a transitional region where the mounting leg transits to the pliers jaw leg and/or the second bolt extending through a free end region of the mounting leg.
2. The pivoting pliers jaw of claim 1 wherein the second bolt is a pivot bolt.
3. The pivoting pliers jaw of claim 1 wherein the at least one accommodation of the pliers jaw plate comprises
a) two accommodations for supporting elements of a die insert which are arranged with a distance in a projection onto the supporting plane and by which at least a component of a crimping force biasing the die insert and having an orientation perpendicular to the supporting plane can be transferred from the die insert to the pliers jaw plate and/or
b) a bore for a mounting screw by which it is possible to mount the die insert to the pliers jaw plate.
4. The pivoting pliers jaw of claim 1 wherein by the first bolt and the second bolt, the pliers jaw plate and a second pliers jaw plate are held on different sides of the supporting plate.
5. The pivoting pliers jaw of claim 4 wherein a thickness of the supporting plate in a region of the overlap equals a thickness of an accommodating space formed between the pliers jaw plates into which a die insert can be inserted.
6. Crimping pliers comprising a pivoting pliers jaw having a design comprising plates,
the pivoting pliers jaw comprising
a) a supporting plate and
b) a pliers jaw plate, which
ba) forms or supports an accommodation for a die insert,
bb) defines a supporting plane of the accommodation for supporting a crimping force biasing the die insert,
bc) is arranged with an overlap on one side of the supporting plate and
bd) is fixed in a region of the overlap by a first bolt and a second bolt at the supporting plate,
c) an angle between
a connecting axis of longitudinal axes of the first bolt and the second bolt and
the supporting plane in a pliers head plane being 90°±30°,
d) the pliers jaw plate comprising a mounting leg and a pliers jaw leg, the mounting leg and the pliers jaw leg being arranged in an L-shape and
e) the first bolt extending through a transitional region where the mounting leg transits to the pliers jaw leg and/or the second bolt extending through a free end region of the mounting leg,
the crimping pliers further comprising a toggle lever drive actuated by hand levers or a drive, one toggle lever of the toggle lever drive being linked to the supporting plate.
7. The crimping pliers of claim 6 wherein the second bolt is a pivot bolt of the crimping pliers which supports the pivoting pliers jaw for being pivoted at a fixed pliers jaw, a pliers head or a fixed pliers part.
