Definitions

  • the invention relates to portable pliers with motor drive for irreversible jamming of C-shaped cramps or the like, in particular for connecting elongated elements, for example edges of wire mesh plates, such as are used for protective structures against landslides and erosions.
  • Portable pliers with motor drive are already known for the purposes mentioned, which have a pair of mirror-symmetrically arranged clamping jaws which are mounted on a support member in their central region, lie symmetrically to a plane which runs parallel to the longitudinal extension of the pliers, and on their free one Ends that protrude outward and are normally spread have seat grooves for the opposite, curved ends of the C-shaped staples, each of which is inserted into the seat in a position with the open staple side facing the ends by means of a thrust plate acting on the back of the stair, which runs parallel to the clamping jaws and is actuated via a rod connected to it in such a way that it executes a reciprocating movement in the longitudinal direction; these pliers also have a stop which prevents the back of the cramp inserted into the seat grooves from retracting when the free ends of the jaws approach each other to clamp the cramps.
  • the thrust plate lies in the plane in which the clamping jaws are located, the rod connected to this being the piston rod of a double-acting, pneumatic working unit.
  • the insertion process of the staples into the seat grooves, which are incorporated into the free end sections of the clamping jaws, is ended as soon as the push plate has reached its end position in the direction of the seat grooves; the cramp is then compressed in its clamped position as the pusher plate retracts to its opposite position.
  • the stop which prevents the back of the staple from retracting when jamming, consists of a snap-in pawl which, under spring action, engages behind the middle part of the back of the staple, which is inserted into the seat grooves at the ends of the jaws.
  • the invention is therefore based on the object of providing a pair of portable pliers of the type outlined at the outset, which does not have the disadvantages described and is able to ensure an effective and safe jamming of staples which are relatively stiff, the weight and the size of the pliers can be reconciled with the requirement of longer and continuous use in the course of a working day even by less powerful operators, especially under the conditions of use on a construction site where metal wire cages or the like are to be set up and assembled.
  • the technical problems lie in finding a solution which ensures that the clamps never deform undesirably during the clamping by the clamping jaws and that the means which act on the clamps during the clamping can exert considerable compressive forces without that the weight and size of the tool exceed the limits for a portable device.
  • a portable pliers with motor drive for irreversible jamming of C-shaped staples or the like which has a pair of mirror-symmetrically arranged clamping jaws which are pivotally mounted on a support member in their central region, lie symmetrically to a plane which is parallel to the longitudinal extension of the Pliers run, and at their free ends, which protrude outward and are usually spread, have seat grooves for the opposite, curved ends of the C-shaped staples, each in a position with the open cramp side facing the said ends , is inserted into the seat by means of a thrust plate acting on the back of the staple, which is actuated via a rod connected to it in such a way that it carries out reciprocating movements in the longitudinal direction, the pliers also having a stop to prevent the back of the back from retracting
  • the cramped seat has inserted cramp when the free one Ends of the clamping jaws approach each other to clamp the staple, this object is achieved according to the invention in that the two clamping jaws are arranged at a distance from
  • a rod is provided for pivoting the clamping jaws, which rod is driven to move back and forth in the longitudinal direction, preferably parallel to the rod connected to the push plate.
  • both the rod for the pivot drive of the clamping jaws and the rod connected to the push plate are each the piston rod of a piston of a double-acting working unit.
  • the working units are preferably hydraulic working units.
  • a switchable electric motor with interposition of clutches and irreversible gears is provided for the reciprocating displacement of the two rods.
  • the portable pliers shown in FIGS. 1 to 11 have a housing 1 with a rear handle 2 and a side handle 3.
  • the housing 1 is fastened to a supporting structure of the pliers, which has a support plate 4 extending in the longitudinal direction.
  • clamping jaws 6, 7 which are mirror-symmetrically identical to one another and which are arranged symmetrically to a longitudinal center plane 8 of the pliers (cf. FIGS. 3 and 7); the longitudinal median plane 8 extends at right angles to the support plate 4.
  • the clamping jaws 6 and 7 are mounted on pivots 9 and 10, respectively, which protrude from the upper side 5 of the support plate 4 and have free end sections which extend beyond the front edge 11 of the support plate 4.
  • Coupling rods 12 and 13 are articulated to the ends of the clamping jaws 6 and 7 opposite these end sections, which are in turn mounted on a slide 15 via a pin 14 which ventilates parallel to the pivot pins 9 and 10.
  • the slider 15 can be moved in the longitudinal direction of the support plate 4 and is guided in its displacement movements by engaging with a lower shoulder 16 in a longitudinal groove 17 which is incorporated into the top 5 of the support plate 4.
  • a rod is connected, which is the piston rod 18 of a piston 19 of a double-acting hydraulic working unit 20.
  • the cylinder 21 of this working unit 20 is attached to a cylindrical support block 22 which extends at right angles to the support plate 4 and is attached to the rear edge thereof, which faces away from the front edge 11.
  • the support block 22 thus forms part of the load-bearing structure of the pliers and serves as a support element for the rear part of the housing 1 with the handle 2.
  • the piston 19 divides the interior of the cylinder 21 into two chambers 23 and 24, which are connected via lines 25 and 26 and via a distributor switch 29, the function of which is explained in more detail below, with a pressure source 27 (cf. FIG. 11) or with a drain 28 can be connected.
  • the free ends of the jaws 6 and 7, which protrude beyond the front edge 11 of the support plate 4, are designed as ends 30 which protrude from the underside 31 of the support plate 4, which is opposite to its upper side 5, on which the jaws 6 and 7 lie .
  • grooves 32 are incorporated, the sections of which lie in the region of the free ends of the clamping jaws 6, 7 are curved in the direction of the longitudinal center plane 8.
  • grooves 32 serve to receive and seat the opposite, curved ends 33 of C-shaped cramps 34 (see FIGS. 4 and 6) which are to be irreversibly clamped with the aid of the pliers, whereby they differ from those in FIGS 6 shown in the form shown in Figure 7 are converted.
  • Each groove 32 merges into a guide groove 35 with a C-shaped cross section, which is shown in FIG.
  • the two mutually opposite guide grooves 35 are incorporated in two longitudinal ribs 36 which protrude from the mutually opposite edges of the underside 31 of the support plate 4. Due to this arrangement, the grooves 32, which are incorporated into the ends 30 of the jaws 6, 7, form extensions of the C-shaped guide grooves 35 when the jaws 6, 7 are in their spread rest position.
  • a thrust plate 37 The longitudinal edges of a thrust plate 37 are slidably mounted in the two guide grooves 35, the groove base surfaces of which have a distance from one another which essentially corresponds to the height of the cramps 34.
  • the thrust plate 37 has at its end facing the ends 30 of the clamping jaws 6, 7 a concave end face 38, the curvature of which corresponds approximately to the curvature of the back 39 of the cramps 34.
  • the push plate 37 is connected to a piston rod 40 of a piston 41, which is slidably mounted in a cylinder 42 of a double-acting hydraulic auxiliary work unit 43, which is also fastened to the support block 22, namely under the cylinder 21 of the work unit 20.
  • the piston 41 divides the interior of the cylinder 42 into two chambers 44 and 45, which can be connected to a line 46 or 47 via a distributor switch 48.
  • the distributor switch 48 can close off the two chambers 44 and 45 to the outside or connect it to the pressure source 47 for the pressure fluid or to the outlet 28, similarly to the way the distributor switch 29 controls the two chambers 23 and 24 of the cylinder 21.
  • Both distribution switches 29 and 48 are controlled by a logic circuit 49 (see FIG. 11). This is actuated when the switch 50 is closed, which can be actuated via a switch button 51 in the rear handle 2, provided that the pressure in the liquid coming from the pressure source 27 (preferably an electric pump) has reached the normal operating pressure for the pliers and a pressure not shown Pressure switch releases the operation of the logic circuit 49.
  • the logic circuit 49 is started. This first actuates the distributor switch 29 so that the chamber 23 of the working unit 20 is connected to the pump 27, so that the piston 19 is advanced in the direction of arrow 52. The piston 41 stops because the logic circuit 49 simultaneously adjusts the distribution switch 48 so that both chambers 44 and 45 of the auxiliary work unit 43 have no connection to the outside.
  • the logic circuit 49 is set so that the switch 50 is now opened by releasing the pressure on the switch button 51.
  • the distributor switch 29 is simultaneously controlled so that the piston 19 is retracted, the free ends of the clamping jaws 6 and 7 being spread into the open position.
  • the auxiliary work unit 43 also pulls back the push plate 37 by actuating the distribution switch 48 by means of the logic circuit 49, the chamber 45 of the auxiliary work unit 43 being connected to the pump 27 and the other chamber 44 to the drain 28 will.
  • the concave end face 38 of the push plate 37 is located immediately behind the junction point of a feed magazine 53 into the space between the two groove bases of the mutually opposite guide grooves 35, which are incorporated into the longitudinal ribs 36 of the support plate 4.
  • a subsequent cramp can move up from the feed magazine 53 and lie with its back 39 in such a position that it rests on the concave end face 38 of the thrust plate 37 (see FIG. 6).
  • the pliers described and designed according to the invention allow irreversible jamming even of very strong cramps and, thanks to the use of hydraulic working units which can exert very high pressure forces, are relatively light in weight and have a small installation space.
  • it fulfills the basic requirements for portable tools and is very reliable due to the simple construction of the retaining means, which prevent the back of the staples from shrinking and irregular deformation of the staples during jamming.
  • a system can be used to pivot the clamping jaws 6 and 7 and to move the push plate 37, which system is shown in FIG.
  • rods 18 and 40 are piston rods of hydraulic working units, as shown in the exemplary embodiment in FIGS. 1 to 11, but to provide them with racks 54 and 55, respectively. These racks are in engagement with a screw spindle 56, 57, which are axially fixed and rotatably mounted on a shaft 58. This can be driven by a reversible AC motor 60, possibly with the interposition of a clutch controlled by a logic circuit 59.
  • a switching sleeve 61 with driving teeth is provided, which is mounted for longitudinal movement on the shaft 58 via a spline and can be shifted accordingly by an electromagnetic switching element 62 by pulses which are supplied to the switching element by the logic circuit 59 which also controls the function of the motor 60.
  • the switching element 62 can be actuated so that the switching sleeve 61 can assume three positions: a first position in which it connects the screw spindle 56 to the shaft 58, a second position in which it connects the screw spindle 57 to the shaft 58, and a third position in which the rotation of the shaft 58 is not transmitted to either of the two screw spindles and in which the rods 18 and 40 are blocked against any axial displacement by the irreversible kinematic connection between the toothed racks and the screw spindles.
  • the guide grooves 35 which are incorporated in the lower longitudinal ribs 36 of the support plate 4, are arranged so that the underside 31 of the support plate 4 and with this also the thrust plate 37 to the top 5 of the support plate 4, on which the clamping jaws 6 and 7 lie, run inclined.
  • the inclination is chosen so that the cramp 34 inserted into the grooves 32 of the clamping jaws 6 and 7 sits in the two grooves 32 at the end of the feed movement of the push plate 37, as shown in FIG. 14; this means that the height of the two grooves 32 is greater than the diameter of the cramp wire. In this way, an exact clamping of the staple 34 is facilitated, which takes on the shape shown in FIG. 16 at the end of the closing movement of the ends 30 of the two clamping jaws 6 and 7.
  • the clamp 34 is prevented from moving downward during the jamming, since a plate 69 is fastened on both sides of the front end section of the underside 31 of the support plate 4 (cf. FIG. 13). This measure can also be taken in the embodiment shown in FIGS. 1 to 11.
  • the logic circuit 49 which controls the operations of the clamp, is not controlled by the pulses which are supplied to the logic circuit 49 by a pressure switch, but by pulses due to the closing and opening of micro-limit switches 63, 64 and 65, 66, which are assigned to the rods 18 and 40 of the pistons 19 and 41 and are actuated by lugs 67 and 68, respectively, which are fastened on these rods (cf. FIG. 17).
  • This variant improves the economy when operating the pliers, increases their functional accuracy and improves safety for the operator.
  • the electric pump 27, the distribution switches 29 and 48 and the components of the electrical circuit which controls the function of the working units 20 and 43 and contains the logic circuit 49 can be accommodated in a compact unit which can be accommodated in a bag or a backpack that the operator can easily carry.
  • connection to an external energy source consists of a cable which has to be connected to a mains socket, which has an extremely favorable influence on the mobility and the ease of use.
  • the jaws 6 and 7 can be designed so that they are mounted on a single pivot which protrudes from the top 5 of the support plate 4 and which takes the place of the two pivot 9 and 10.
  • control of the electric motor 60 in the exemplary embodiment in FIG. 12 can be carried out by systems which operate analogously to that in FIG.
