Definitions

the invention relates to pliers according to the preamble of the claim 1.
Such pliers the z. B. can be designed as crimping pliers already known from EP 0 516 598. These pliers have a pair of stamps for processing objects. The stamp members of the pair of stamps are coupled with each other via guide pins and by one the axis of rotation lying in the device plane can be rotated.
the invention has for its object a pair of pliers of the aforementioned To create a way in which a safe already at the beginning of the pressing process Management of the processing elements is guaranteed.
a pair of pliers according to the invention is characterized in that the guide pins are designed and arranged so that they are in each of the working positions and at least with the pliers closed, the other mentioned protrude through the machining elements.
the processing elements guided by means of two guide pins can be at any distance from each other on the processing elements be positioned, with your arrangement preferred is carried out in such a way that the pressing elements are exerted during the pressing process Torques are compensated for as well as possible in order to avoid tilting to avoid the machining elements with the guide pins. So can the guide pins z. B. offset or parallel on a straight line to the longitudinal direction of the processing elements. The latter Arrangement z. B. the advantage that the processing elements in one Direction particularly narrow (slightly larger than the largest diameter the guide pins).
the guide pins are preferably located on only one processing element, thus consequently in corresponding guide bores of the other processing element.
each of the processing elements also only has one guide pin have, which then in a corresponding guide bore of the would intervene in each other processing element.
the Stability could be further improved.
the machining elements In the preferred embodiment lie in one of the processing positions the machining elements the guide pins in one perpendicular to the plane of the pliers, being on the side of a Pliers jaws can be passed. Consequently, is closed Position of the processing elements of the jaws between the parallel Guide pins. This makes the guide pins special be long, but with the processing elements in the open position must not run next to the jaws of the pliers, because otherwise a rotation of the processing elements in a different working position is no longer possible.
the jaws are at least hollow in the area of the processing elements.
the processing elements can namely the guide pins lie in the plane of the pliers and thus when the Machining elements in this hollow area of the jaws immerse yourself.
the pliers jaws can alternatively also by two plates arranged at a distance from one another, what has a positive effect on the total weight of the pliers.
the jaws are designed with locking elements.
the processing elements one pivot each from one of the jaws of the pliers worn bearing held.
At least one of the locking elements on which the guide pins can be moved are consists of a spring clip provided with locking lugs, the lies in a plane perpendicular to the pivot and with its Lugs engage in longitudinal grooves of the pivot. In this way can be formed a relatively short camp, which in turn a small Distance of the guide pins from each other allows, so that for the case that the guide pins engage in the cavity of the jaw, the processing elements can be kept small.
the bearing is as Block formed with a through hole for the pin, thus can be easily plugged on.
Figure 1 shows a perspective side view of the front part of a open pliers 1 with an upper jaw 2 and a lower Pliers jaws 3 in section.
the jaws 2, 3 are each made of two in a distance from each other parallel plates 2a, 2b; 3a, 3b (3b is shown in Figure 2).
Holes 4, 5, 6 are provided in the plates 2a, 2b: 3a, 3b, respectively to which bolts (not shown) serving as spacers are inserted, so the respective plates 2a and 2b as well as 3a and 3b in a fixed Keep distance from each other and form the jaws 2 and 3.
the two jaws 2, 3 are each in the plates 2a, 2b; 3a, 3b trained bores 7, namely by a in this Holes 7 inserted bolt (not shown), which consequently as a common
the axis of rotation serves to pivot the jaws 2, 3 are.
the processing element 8 points in the direction of the processing element 9 extending stamp approach 10, the closed Pliers 1 from a corresponding one formed in the processing element 9 Bulge 11 is added.
Figure 1 also shows a bearing 14 in which the lower processing element 9 is rotatably mounted about an axis lying in the plane of the pliers.
the bearing 14 is designed as a block 15 and faces opposite Side axles 16a, 16b on (16b is not shown in Figure 1).
FIG. 1 further shows one in the plate 2b of the upper jaw 2 formed bore 17 into which an axle shoulder of a second bearing 19th (see Figure 2), in which the upper processing element 8 rotatable by one Axis lying in the pliers plane is engaged.
This camp and the bearing 14 is therefore between the plates 2a, 2b of the upper jaw 2 and, respectively, between the plates 3a and 3b of the lower jaw 3 and are therefore relative to the jaws 2, 3 on the Axle lugs 16a, 16b pivotable.
the two processing elements are via parallel guide pins 12, 13 8 and 9 performed relative to each other.
the guide pins 8, 9 attached to the processing element 8 and protrude into through holes into the other processing element 9.
FIG. 2 shows a perspective side view of the front part of FIG closed pliers 1, the processing elements 8, 9 in one first working position.
the one on the editing element 8 trained stamp approach 10 with closed pliers 1 completely from the bulge formed in the processing element 9 11 added.
the guide pins are immersed when the pliers 1 are closed 12 and 13 in the lower pliers jaws formed by the plate 3a, 3b 3 and protrude through the lower processing element 9.
a hole 18 is formed in the plate 3b of the lower jaw 3, into which the axle shoulder 16a of the bearing 14 from FIG. 1 engages.
the distance between the plates 3a, 3b of the lower jaw is 3 in the area of the bore 7 slightly smaller than the distance of the Plates 2a, 2b of the upper jaw 2.
the lower Pliers jaws 3 at least partially in the through the plates 2a, 2b formed gap of the upper jaw 2 are pushed.
FIG. 2 also shows one formed on the processing element 8 Pivot 23 which projects through the bearing 19 and over which the machining element 8 is rotatable.
the processing element 9 is similar Way in between the plates 3a, 3b of the lower jaw 3 arranged bearings 14 rotatable. Since both processing elements 8, 9 are connected to each other via the guide pins 12, 13, let them only around the pivots 23 lying in the plane of the pliers rotate.
FIG. 3 shows a perspective side view of the front part of FIG closed pliers 1 with the processing elements 8, 9 in the first Working position.
the pivot 23 of the machining element 8 is by means of a Snap rings 24 secured against slipping out of the bearing 19. Corresponding applies to the pivot of the machining element 9.
FIG. 3 also shows the connecting link 26 already mentioned, which is connected to the lower jaw 3 is coupled.
FIG. 4 shows the bearing 14 designed as block 15.
the bearing is similar 19 trained.
On two opposite side faces are each the axles 16a and 16b formed, which in the corresponding Bores 17, 17 and 18, 18 of the jaws 2, 3 engage so as to Bearings 14, 19 to be rotatably coupled to these.
FIG. 5 shows the processing element 8 of the exemplary embodiment according to FIGS. 1 to 3.
the pivot pin 23 has four opposite grooves 28 which run in its longitudinal direction.
the locking element is designed as a U-shaped spring clip 27, which on its has two legs inwardly pointing locking lugs 29 which in the respective working position of the processing elements 8, 9 in the corresponding Engage the circumferential grooves 28 of the pivot pin 23.
FIG. 6 shows a perspective side view of the front part of FIG semi-closed pliers 1 according to Figure 1, with the processing elements 8, 9 are in a second processing position, which are opposite the first machining position is rotated by 90 °.
the guide pins 12, 13 lie in a perpendicular to the pliers plane level, through the work jaws 2, 3 and with them connected pliers handles is clamped.
the guide pins 12, 13 are already partially immersed closed pliers 1 by those formed in the processing element 9 Through guide holes.
the guide pin 12 runs thereby past the outside of the plate 3b of the jaw 3.
the processing elements 8, 9 are also minimal in both working positions rotatable about the axis formed by the axles 16a, 16b. For this reason, it is necessary that the processing elements 8, 9 not directly on the end faces of the plates 2a, 2b or 3a, 3b Pliers jaws 2, 3 rest, but a certain distance from them adhere to avoid jamming.
