Crimping pliers and die half unit
The invention relates to a die half unit. The die half unit comprises a die half and a die half bearing comprising a bearing body. The bearing body comprises a bearing cross-section. The bearing cross section has a securing extension in a direction transvers to a securing orientation and has an insertion extension transvers to an insertion orientation. The securing extension is larger than the insertion extension. Furthermore, the bearing body comprises a latching or locking element by which the bearing body can be latched or locked with a counter-holding element of a bearing accommodation. The bearing cross-section and the latching or locking element provide alternative coupling options for a connection to a bearing accommodation of a pliers jaw.
1 . A die half unit for use with crimping pliers having a bearing accommodation on a pliers jaw, the die half unit comprising:
a) a die half and
b) a die half bearing comprising a bearing body positionable about and between a securing orientation and an insertion orientation that is at an acute angle relative to the securing orientation,
c) the bearing body comprising both
ca) a bearing cross-section that comprises at least one cylinder segment portion and a flattening such that the bearing cross-section has a securing extension in a direction transverse to the securing orientation and has an insertion extension transverse to the insertion orientation, the securing extension being larger than the insertion extension and
cb) a latching or locking element by which the bearing body can be selectively latched or locked with a counter-holding element of the bearing accommodation, the latching or locking element defining a latching or locking recess in the bearing body, wherein the counter-holding element selectively engages the latching or locking recess to provide a locking effect,
d) the bearing cross-section and the latching or locking element providing alternative coupling options for a connection to the bearing accommodation of the pliers jaw.
2 . The die half unit of claim 1 , further comprising a rotational bearing by which the die half is supported for being rotated about a crimping axis relative to the bearing body.
3 . The die half unit of claim 1 , wherein
a diameter of the cylinder segment portion corresponds to the securing extension, and
at the flattening the bearing body comprises the insertion extension.
4 . The die half unit of claim 1 wherein the bearing cross-section and the latching or locking element are arranged adjacent to each other when viewing along a pivot axis of the die half bearing.
5 . The die half unit of claim 1 wherein the bearing cross- section is hook-shaped.
6 . The die half unit of claim 1 , wherein the bearing body is detachably latched or locked with the counter-holding element of the bearing accommodation.
7 . The die half unit of claim 1 wherein the latching or locking element comprises a protrusion extending away from the at least one cylinder segment portion to define the latching or locking recess.
8 . The die half unit of claim 7 wherein the latching or locking recess is defined between the flattening and the protrusion.
9 . Crimping pliers comprising a die with a first die half unit supported on a first pliers jaw and a second die half unit supported on a second pliers jaw, wherein
a) the first die half unit comprises a first die half and a first bearing body, the first bearing body comprising a first bearing cross-section which has a securing extension in a direction transverse to a securing orientation and has an insertion extension transverse to an insertion orientation, the securing extension being larger than the insertion extension, the first bearing body being supported in a first bearing accommodation of the first pliers jaw, wherein the first bearing body can be inserted in the insertion orientation into the first bearing accommodation, the first bearing body can be pivoted in the first bearing accommodation by a pivoting movement from the insertion orientation into the securing orientation wherein the first bearing body forms a positive engagement with the first bearing accommodation in the direction of the securing orientation,
b) the second die half unit comprises a second die half and a second bearing body, the second bearing body being supported in a second bearing accommodation of the second pliers jaw, the second bearing body comprising a latching or locking element, the second bearing accommodation comprising a counter-holding element, the latching or locking element defining a latching or locking recess in the second bearing body, the second bearing body and the second bearing accommodation being connected to each other by a latching or locking device established by the engagement of the latching or locking element and the counter-holding element, and the latching or locking element by which the latching or locking recess of the second bearing body can be selectively latched or locked with the counter-holding element of the second bearing accommodation.
10 . The crimping pliers of claim 9 wherein the second bearing body comprises at least one cylinder segment portion and a flattening, and wherein the latching or locking element comprises a protrusion extending away from the at least one cylinder segment portion to define the latching or locking recess.
11 . The crimping pliers of claim 10 wherein the latching or locking recess is defined between the flattening and the protrusion.
12 . The crimping pliers of claim 9
wherein the second bearing body further comprises a second bearing cross-section with a securing extension and an insertion extension, and
wherein the first bearing body further comprises a latching or locking element,
wherein the bearing cross-section of the first bearing body and the bearing cross-section of the second bearing body are identical, and wherein the latching or locking element of the first bearing body and the latching or locking element of the second bearing body are identical.
13 . A die half unit for use with crimping pliers for crimping a workpiece during a crimping process, the crimping pliers having a pliers jaw and a bearing accommodation on the pliers jaw, wherein the bearing accommodation comprises a counter-holding element, the die half unit comprising:
a die half having a die half contour that interacts with the workpiece during the crimping process; and
a die half bearing comprising a bearing body positionable about and between a securing orientation and an insertion orientation that is at an acute angle relative to the securing orientation,
wherein the bearing body comprises:
a bearing cross-section that has a securing extension in a direction transverse to the securing orientation and an insertion extension transverse to the insertion orientation, the securing extension being larger than the insertion extension; and
a locking element defining a latching or locking recess,
wherein the bearing body is selectively, detachably connectable to the bearing accommodation both by the bearing cross-section and by engagement of the latching or locking recess of the locking element to the counter-holding element.
