Definitions

  • the invention relates to a manually operable blind riveting tool with a device housing, a front sleeve arranged on the front of the device housing, in the front end of which a mouthpiece for receiving a pulling mandrel is fixed, a chuck arranged in the front sleeve behind the mouthpiece for the pulling mandrel, which a movable traction piston, which extends through the device housing and is designed in its interior as a discharge channel for torn off mandrels, and with two articulated levers on the side of the device housing for transmitting an axial force component to the mandrel which leads to a stroke during the actual riveting process.
  • Hand riveters of the type mentioned are well known.
  • the two lever arms must first be opened completely.
  • the pulling piston is moved forward in the device housing and the chuck is opened by a positive connection with the complementary mouthpiece, so that the mandrel of the blind rivet to be inserted can be inserted into the mouthpiece.
  • the two articulated levers are now closed again until the mandrel is gripped by the retracting chuck.
  • an additional axial force component is now transmitted to the mandrel via the pulling piston by further pressing the two lever arms inwards. whereby this breaks off with the formation of the closing head at a predetermined predetermined breaking point.
  • blind riveting devices Since the opening angle of the articulated lever increases with the actual diameter of the mandrel during the actual riveting process, the force required to set a rivet connection increases with the size and strength of the blind rivet to be set in conventional blind riveting devices. In practice, a set of different blind riveting devices adapted to the respective rivet dimensions is usually used to solve this problem. It is also known to use blind riveting devices with an exchangeable front sleeve and, depending on the size and strength of the blind rivet to be fitted, to adjust the force appropriately by means of an appropriately dimensioned sleeve.
  • a blind riveting device which essentially consists of a body, a pulling device and a chuck.
  • the setting of the lever force or the stroke takes place in that a protruding threaded connector is attached to a bridge section, onto which the pulling device can be screwed.
  • a disadvantage of this known blind riveting device is that when the articulated arms for setting rivets are actuated, the adjustment mechanism is also moved back and forth.
  • US Pat. No. 4,653,308 describes a mechanical blind riveting device with which blind rivets of different sizes and thicknesses can be set with essentially the same amount of force.
  • an adjustable lever mechanism which consists of a tension rod, an adjusting screw and a guide or yoke element on which articulated arms are articulated via articulated pieces.
  • the leverage can now be changed in that the adjusting screw, which is screwed onto the tension rod, is turned in the direction of a mouthpiece or turned away from it. This means that an axial displacement of the yoke element with respect to the tension rod ensures the setting of the lever force.
  • the invention is therefore based on the object of making available a hand riveting device of the type mentioned at the outset which enables a safe and firm setting of the stroke over numerous rivet setting cycles and with which the flexibility in using the hand riveting device is increased and the maintenance and repair work is reduced without any outlay on equipment becomes.
  • the front sleeve can be screwed into the device housing and can be locked in its axial position by means of a lock nut steplessly with respect to the chuck and in that way the stroke of the pulling piston can be adjusted by changing the distance between the mouthpiece and the chuck. Since the opening of the chuck takes place via a positive connection with the mouthpiece, the opening angle of the articulated lever can be optimally adjusted by changing the distance between the mouthpiece and the chuck according to the invention with regard to the force required for the riveting process depending on the size and strength of the blind rivets to be set. When setting blind rivets of different diameters, the opening angle of the articulated lever can be changed very easily and quickly according to the respective requirements, and the force required to carry out the riveting process can be set as desired.
  • the front sleeve is expediently provided with an external thread at its rear end, the diameter of the thread provided rear area of the front sleeve is less than that of the front area, so that the front area acts as a stop for the lock nut.
  • the minimum opening angle of the articulated lever which still enables a sufficiently strong lifting movement of the pulling piston for the correct execution of a riveting process, can be determined.
  • a preferred embodiment is characterized in that only a rear section of the lock nut is provided with an internal thread, and that the inside diameter of the front section of the lock nut, which is not provided with an internal thread, is larger than that of the rear section and larger than that of the front section threaded area of the front sleeve.
  • the end of the threaded rear portion of the front sleeve can be used as a mark up to which it is possible to unscrew the front sleeve from the device housing without impairing the operational safety.
  • the lateral surface of the lock nut is advantageously designed to be edged or corrugated in order to be easier to operate manually.
  • Rotational markings are advantageously provided on the front sleeve.
  • a front sleeve 14 is arranged so that it can be screwed in on the front of a device housing 12 and is locked in its axial position by means of a lock nut 16.
  • the front sleeve 14 is on her provided at the rear end with an external thread, the diameter of the threaded area being smaller than that of the front, non-threaded area, so that the front area acts as a stop for the lock nut 16. This is only provided with an internal thread in a rear section.
  • the inside diameter of the front, not provided with an internally threaded portion of the lock nut 16 is larger than that of the front, not provided with a threaded portion of the front sleeve 14, so that it can be screwed into the device housing 12 until it stops at the rear portion of the lock nut 16 is.
  • the thread of the front housing 14 is protected against possible damage by the lock nut under normal operating conditions.
  • the beginning of the non-threaded area of the front sleeve 14 can be used as a mark up to which it is possible to unscrew the front sleeve 14 from the device housing 16 without impairing safety.
  • the circumferential surface of the lock nut 16 is designed with ribbing or corrugation with a view to good manual operability.
  • a mouthpiece 18 for receiving a pulling mandrel (not shown) is fixed.
  • the mouthpiece 18 can either be firmly connected to the front sleeve 14 or, for example, be designed to be exchangeable by means of a screw connection.
  • a chuck 20 for the mandrel is arranged behind the mouthpiece 18.
  • the chuck 20 is connected via a clamping sleeve 22 to a movable pulling piston 24 which extends through the device housing 12 and is designed in its interior as a discharge channel 26 for torn off pulling mandrels.
  • the rear end of the tension piston 24 is fixedly connected to a guide housing 28 which is arranged on a guide sleeve 30 so as to be axially displaceable.
  • the guide sleeve 30 is fixed at its front end to the rear Connected end of the device housing 12 and surrounds the pulling piston 24 between the device housing 12 and guide housing 28.
  • the guide channel 26 opens out through an opening 32 into a collecting container 34 for torn off pulling mandrels in order to avoid a risk of injury to the operator due to pulling mandrels lying around.
  • the collecting container 34 is pushed onto the rear, cylindrical end of the guide housing 28. However, it can also be screwed onto the guide housing 28.
  • Two pliers legs 38 are laterally attached to the guide housing 28 with bolts 36.
  • the front end of the pliers legs 38 is articulated with the aid of a threaded bolt 40 and a lock nut 41 to two lateral articulated levers 42 which are fastened to the device housing 12 at their front end by bolts 44.
  • the rear end of the articulated lever 42 is provided with handles 46 made of plastic.
  • the surface of the handle 46 is designed to be rimmed to prevent slipping during the riveting process. To increase security, they are also plate-shaped in their front area 48.
  • Fig. 2 shows the front part of the hand riveting device 10 according to the invention with the articulated levers 42 fully open.
  • the pulling piston 24 is thereby in the foremost position, so that the chuck 20 is completely opened via a positive connection with the complementary mouthpiece 18 for receiving a pulling mandrel (not shown) is.
  • the front sleeve 14 is screwed out of the device housing 12 so far that its threaded rear area ends with the front end of the lock nut. In this way, the thread is reliably protected against possible damage.
  • This position simultaneously marks the position up to which the hand riveting device according to the invention can be used without impairing safety, so that the opening angle ⁇ of the articulated lever 42 (see FIG. 4) is its maximum value reached.
  • the opening angle of the articulated lever required for minimal effort to carry out the riveting process can thus be set in a targeted manner.
  • the present invention thus makes a hand-held riveting tool available which enables riveting processes with blind rivets of different diameters in a simple manner and without any equipment outlay, with essentially the same amount of force.
