Abstract
The invention relates to crimping pliers and a method of assembling crimping pliers. According to the invention, a coupling of a crimping pliers head (32) to a crimping pliers actuation assembly group (1) is provided by coupling recesses (45, 46) and coupling elements (22, 23) arranged in the coupling recesses (45, 46). A re-exit of the coupling elements (22, 23) from the coupling recesses (45, 46) is prevented by a spring device which is effective between the die halves (35, 37) for biasing the movable die half (37) in opening direction.
Claims14
Crimping pliers comprising
- a) two hand levers,
- b) a pivot bolt via which the hand levers are pivotably connected to one another,
- c) two pulling bars linked to the hand levers at a distance from the pivot bolt,
- d) a crimping pliers head with
- da) a pliers head frame,
- db) a spring device and
- dc) a die half, which
- is guided displaceably in a direction of a crimping axis on the pliers head frame,
- is supported by the spring device on the pliers head frame in such a way that the spring device biases the die half in an opening direction, and
- has a pivot bolt accommodation which is open on one side,
- e) the pulling bars being connected to the pliers head frame via coupling devices, the pivot bolt being arranged in the pivot bolt accommodation, a pivoting of the hand levers causing a relative movement of the die half with respect to the pliers head frame, and a movement of the die half and a pivoting of the hand levers taking place in a pliers head plane,
- f) the coupling devices each comprising a coupling recess open on one side and a coupling element, wherein the coupling between the coupling recess and the coupling element
- fa) is established by means of a pivoting movement of the pulling bar in the pliers head plane and by means of an entry of the coupling element into the coupling recess brought about by this pivoting movement, and
- fb) is secured by the spring device.
A method for assembling crimping pliers with
- a) two hand levers,
- b) a pivot bolt by which the hand levers are pivotably connected to each other,
- c) two pulling bars linked to the hand levers at a distance from the pivot bolt,
- d) a crimping pliers head with
- da) a pliers head frame,
- db) a spring device and
- dc) a die half, which
- is guided displaceably in a direction of a crimping axis on the pliers head frame,
- is supported by the spring means on the pliers head frame in such a way that the spring device biases the die half in an opening direction, and
- comprises a pivot bolt accommodation being open on one side,
- e) the pulling bars being connected to the pliers head frame via a coupling device, the pivot bolt being arranged in the pivot bolt accommodation and a pivoting of the hand levers in a closing direction causing a relative movement of the die half with respect to the pliers head frame in closing direction and
- f) the coupling devices each comprising a coupling recess being open on one side and a coupling element, the coupling element being inserted into the coupling recess and being secured by the spring device against exiting from the coupling recess,
- with the following method steps:
- inserting the pivot bolt into the pivot bolt accommodation of the die half and
- connecting the pulling bars to the crimping pliers head by entering of the coupling elements into the coupling recesses with simultaneous compression of the spring device in such a way that as a result of the bias by the spring device the coupling elements are secured against exiting from the coupling recesses.
