Definitions

  • the invention relates to a hand rivet pliers with a Traction element that is relative along a pulling direction is displaceable to a housing, a first handle lever, which is pivotable relative to the housing about a pivot point and a second handle lever.
  • blind rivet When inserting a blind rivet, the blind rivet is included its rivet shank inserted into an opening. Then the mandrel is pulled out. With this movement the rivet shank is deformed on the invisible side. The mandrel breaks after a certain movement off and the blind rivet is set.
  • a similar approach takes place when setting blind rivet nuts. Indeed there is usually a pin in the Blind rivet nut screwed in after deforming do not tear off the blind rivet nut in its opening should, but is screwed out again.
  • the blind rivet is placed in the Blind rivet pliers inserted until the rivet head on one Abutment comes to the plant.
  • the mandrel is used here seized by the tension element. If now the two handle levers towards each other, then the tension element moved away from the abutment so that the mandrel relative pulled to the blind rivet.
  • blind rivet pliers of the type mentioned at the beginning are out DE 31 24 648 A1 known.
  • the handle lever that is used to actuate the tension element with the Thumb or the ball of the thumb operated.
  • the handle lever itself is designed as a one-armed lever that opens another two-armed lever acts on the upper End of the tension element is attached.
  • US 4 932 638 shows pliers for setting expansion bolts, where the handle lever on clamping plate acts, which are arranged around the tension element. When the handle lever is actuated, it wedges a clamping plate on the tension element. Another move of the handle lever then leads to a shift of the tension element.
  • DD 130 757 A1 shows blind rivet pliers articulated head, with its variable length Part arranged between the end points of two levers which are formed by the handles. A relatively large leverage ratio is achieved.
  • blind rivet pliers can no longer be operated with one hand. This is true for the design according to DE 31 24 648 A1 defused by the fact that according to Art a ratchet a multiple actuation of the handle lever allowed in a single setting process. Arise here but sometimes considerable due to the many redirections Loss of friction, so sat the one applied by the user Hand force only incomplete to set the blind rivet is available.
  • the invention has for its object the handling to simplify blind rivet pliers.
  • This task is the hand blind rivet pliers type mentioned solved in that between the first lever and the pulling element a connecting rod gear arranged with a variable transmission ratio is.
  • the Swiveling movement of the first handle lever in a simple way and implemented in the linear movement of the tension element become. This can usually be done relatively reach a few hinge points where losses occur can, so that the user applied Hand power can be used to a large extent To put a blind rivet.
  • the connecting rod transmission has a variable one Transmission ratio. If the first Handle lever is pivoted through a certain angle, does this depending on the position of the handle lever different propulsion routes of the tension element result. This takes into account the knowledge that a user's hand power over his grip area is not constant. The hand force is extended Rather, the hand is smaller than when it is almost closed Hand.
  • the gear ratio falls from one Starting position in which the first handle lever is the largest Has distance from the second handle lever up to an end position in which the first handle lever the second handle lever is approximated.
  • the first handle lever places the pull piece at the beginning of the movement a smaller way back than at the end. Gaps or jumps are avoided. It results in a very pleasant working behavior with the blind rivet pliers.
  • the connecting rod transmission preferably has an intermediate lever on, which is articulated on the first handle lever and by one Pivot point is pivotable and with the tension element is in engagement, the site of engagement, the Pivot point and the pivot point an obtuse angle Form a triangle. Because the points mentioned If you form an obtuse-angled triangle, you reach several Advantages. First, there is the change in angle at the point of intervention relatively small, so that only very small Frictional losses occur. On the other hand you can the desired course through the obtuse-angled triangle of the gear ratio relatively precisely.
  • the obtuse angle is preferably the result in the area of the fulcrum so that you can choose by of the angle can predetermine which component of the movement of the first handle lever for propelling the tension element is used.
  • the triangle advantageously remains over the entire working area of the first handle lever at an obtuse angle. This includes a right angle as the limit. At this limit, the largest component to move of the tension element used.
  • the intermediate lever on the tension element is preferably different Positions definable. So you can multi-stage setting of the Reach blind rivets.
  • the tension element is first by a predetermined maximum distance shifted. This route In many cases it is not enough to close the blind rivet put. If the tension element remains in this position, can be done by swiveling back the first handle the intermediate lever back to its starting position move where he attacks the traction element again, this time but in a different position, namely a little further against the direction of the train. You can do the total stroke divide the tension element into many individual strokes. Accordingly is only a smaller one for each individual stroke Force required.
  • the tension element one with the Intermediate lever has interacting teeth.
  • the design also has the advantage that you always defined intervention points or locations. Man does not have to be done by moving or tilting the Intermediate lever opposite the tension element for the necessary Care intervention.
  • a pawl is preferably detachably connected to the tension element engaged. The pawl secures against that the tension element when the intermediate lever in its Starting position is retracted, too walks back against the direction of the train.
  • the pawl on the same surface area of the tension element as the Intermediate lever acts. This has two advantages. On the one hand is a processing of the tension element, for example for training the toothing, only necessary in a single area. Secondly, it ensures that the pawl in the same way, about the same division, can act on the tension element like the intermediate lever also.
  • the intermediate lever is advantageously in the starting position the first handle lever on an axis, which forms the fulcrum of the first handle lever. On this way it is relatively easy to get the procedure between the intermediate lever and the tension element to solve.
  • the first lever only has to be over his Starting position forward, i.e. against his working direction, be swung out. The distance then forms between the pivot point and the fulcrum a lever arm with which it is possible to use the intermediate lever to lift out of engagement with the tension element.
  • the term "concern" is of course taken into account understand the usual manufacturing tolerances. A small distance can occur.
  • an axis that is the pivot point of the Forms intermediate lever on the first handle lever in the Starting position on the pawl. If the first Handle lever swung forward beyond the starting position then not only does the intermediate lever release, but also the pawl.
  • the first handle lever is preferably a finger lever trained, i.e. it is placed on the side where the blind rivet is also inserted into the blind rivet pliers becomes. This corresponds more to the "pistol feeling" than actuation by the thumb or the ball of the thumb.
  • the riveting pliers can be guided more precisely.
  • the housing lies calm because only the fingers are moved. This will cause the housing to tilt relative to Avoided rivets. The risk that when setting the blind rivet an unwanted relocation is kept to a minimum.
  • the pulling element is advantageously on the connecting rod gear opposite side supported.
  • the tension element can therefore the forces that act perpendicular to it, do not dodge, so that the engagement between the Connecting rod gear and the traction element always preserved remains.
  • the tension element preferably has a return spring and a jaw spring, both springs on Housing are supported.
  • a return spring is for the traction element required so that it after setting the blind rivet is returned to its starting position can be, for example, if the Pawl and the intermediate lever out of engagement with be brought to the tension element. If the tension element in its starting position is pushed back, it is also required that the jaws release the mandrel so that it can hold a new mandrels are available. Now that both feathers are supported on the housing, both springs also serve to reset the tension element. Since both of them The corresponding supports can be supported be relatively stable.
  • the tension element has a damping ring having.
  • a damping ring can be formed by an O-ring, for example surrounds the tension element at a position where it with a Internal slope of the housing comes into contact. Of the Damping ring prevents uncomfortable hitting, when the pawl and the intermediate lever unlock become.
  • the housing advantageously has a removable collecting container on. Torn in the collecting container Rivets are collected. The risk of accidents in Area of work is kept small because no torn rivets are lying around freely.
  • a blind rivet pliers 1 is not used for setting Blind rivets or blind rivet nuts shown.
  • a blind rivet with its rivet mandrel a mouthpiece 2 of the rivet pliers inserted until it is there.
  • the blind rivet pliers have a first movable handle lever 3 and a second handle lever 4 on, which is connected to a housing 5, on which also the mouthpiece 2 is attached. If now the first Handle lever 3 pivoted toward the second handle lever 4 the rivet mandrel is gripped and then exerted a tensile force on the mandrel that the Rivet mandrel with its thickened end a bit through the rivet shaft and this to the closing head deformed. In the illustrated embodiment this requires a force of 7,000 N.
  • variable power transmission one carries the physiological conditions, which are shown in Fig. 3 are shown.
  • the human hand can then if she closes her grip further, a higher force apply. Accordingly, the opening width is horizontal applied by hand in percent. Perpendicular is the normal force in Newtons (N). Out of it it can be seen that the hand is when it is its largest Has only taken up about 50% of the opening width Can exert force with an opening width of 40%. If now by a corresponding selected variable transmission ratio, i.e. a course of the translation, the force when pressed of the first handle lever rises, then for the user a very comfortable working behavior despite a largely constant traction on the mouthpiece 2nd
  • the mouthpiece 2 is screwed into the housing 5, the again integrally connected to the second handle lever 4 is.
  • the housing is shown closed here. However, this is not an unconditional requirement for the functionality of the blind rivet pliers 1.
  • the first handle lever 3 is about an axis 6 in the housing 5 pivotable.
  • the axis 6 forms a fulcrum for the first handle lever 3.
  • on the first handle lever 3 is an intermediate lever 7 pivotally mounted about an axis 8, which is a pivot point for the intermediate lever forms on the first handle lever 3. This Construction can also be seen in Fig. 6.
  • the intermediate lever 7 has at its other end, i.e. the end facing away from the axis 8, a toothing 9 with which the intermediate lever 7 with a tension element 10 is engaged.
  • the tension element 10 points to this a toothing 11, which along in the direction of pull of the tension element 10 extends over an area which much longer than the toothing 9 on the intermediate lever 7 is.
  • FIGS. 4 and 6 shows, it is therefore possible that the intermediate lever 7th along the tension element 10 at different positions comes into engagement with the tension element 10.
  • the first handle lever forms 3 together with the intermediate lever 7 a connecting rod gear.
  • the pivot point of axis 6, the pivot point of axis 8 and the engagement point 9 (for the purpose of this consideration the rearmost point of the toothing 9 is the point of engagement considered) form an obtuse angle Triangle, the obtuse angle being arranged on axis 6 is.

  • the swivel angle is chosen is that the triangle spans the entire swivel range of the first handle lever 3 remains obtuse, the angle in the area of axis 6 always at least 90 ° is, the angular movements can no longer be simple be linearized. Rather, there is a clear one Increase in the displacement of the tension element 10 with increasing pivoting angle of the first handle lever 3.
  • the tension element 10 is on the opposite of the toothing 11 Side by a roller 12 in the housing 5 supported. Even the small ones, transverse to the direction of pull of the Tensile element 10 acting forces, so can not do so cause the tension element 10 out of its orientation is pushed out with the direction of pull.
