Definitions

  • Joining device preferably for setting rivets, for clinching or for punching Description
  • the present invention relates to a joining device, preferably for setting rivets, for clinching or for punching.
  • Previously known joining devices for example for semi-hollow punching, Voilstanznieten or clinching, have a C-shaped support. At one end of the C-shaped support is a solid die. At the other end of the C-shaped support a movable punch is arranged. The objects to be joined are arranged between the die and the stamp.
  • the drive is carried out hydraulically, pneumatically or servo-electric. Typical drive lengths over which the punch must be movable are greater than 350 mm. This long interference geometry leads to accessibility problems at the joint. Flanges must be hired, joining facilities turned, vehicle concepts changed to ensure accessibility with existing plant technology. At some joints, these above-mentioned cheap joining options must be replaced by costly methods, such as blind rivets.
  • the object is achieved by a joining device, preferably for setting rivets, for clinching or punching, comprising a die and a liner linearbeweg union stamp.
  • a joining device preferably for setting rivets, for clinching or punching, comprising a die and a liner linearbeweg union stamp.
  • both the die and the stamp is located on the carrier, which is preferably C-shaped.
  • the object to be joined can be positioned between the punch and the die.
  • the joining device comprises a Vorhubech for performing a Vorhubterrorism of the punch and a Hähubech for carrying out a working stroke of the punch.
  • the power stroke unit is configured to actuate the punch with a greater force and / or a shorter linear movement, as the Vorhubech.
  • the linear movement of the punch carried out by the pre-stroke unit can also be referred to as rapid lift or feed stroke. It is crucial that the punch is moved very quickly and over a long distance to the joint by means of the Vorhubech. During the pre-stroke no or only a very small force acts on the punch. The mechanism for carrying out the preliminary stroke can thus act very quickly and does not have to apply any joining force. As soon as the punch or downholder reaches the joint, the working stroke unit acts. This then only has to move the stamp over a very short distance, but with a great force. During the working stroke, for example, the punch only has to be moved over a distance of less than approximately 20 mm, but with a force of 5 to 100 kN.
  • the stamp Due to the inventive division of the joining device in a Vorhubaji and a Hähubaji the stamp can be closed very quickly and reopened. This results in improved accessibility to joints and it can simple joining methods, such as the semi-hollow punch riveting or Votlstanznieten or clinching can be used.
  • the joining device according to the invention is relatively lightweight and can be moved for example by robots and thus used for the assembly of vehicle bodies. This results in a cost and space savings.
  • Pre-lift unit is a quick opening and closing of the punch possible, which reduces the assembly times and thus the costs.
  • the pre-lifting unit comprises a first spindle for moving the punch
  • the working stroke unit comprises a second spindle for moving the punch.
  • the spindles have in particular different pitches, so that different speeds and forces can be generated by means of different spindles.
  • the two spindles are arranged one inside the other. As a result, a compact construction of the joining device is possible.
  • the two spindles are drive-connected via a differential gear with a common drive.
  • the differential gear By means of the differential gear, the first spindle of the Vorhubü is first actuated when closing the punch and then the second spindle of the working stroke unit is actuated.
  • the drive is preferably designed as an electric motor or hydraulic motor.
  • the pre-stroke unit comprises a first spindle.
  • This first spindle is connected to the stamp.
  • the working stroke unit comprises a sleeve guided linearly movably on the support and a movement device.
  • the movement device is designed for linear movement of this sleeve.
  • the first spindle of the Vorhubech is guided in this sleeve.
  • There is a driver between the first spindle and the sleeve so that the first spindle together with the punch is moved by linear movement of the sleeve.
  • a backdrop is preferably provided.
  • This backdrop includes an oblique groove.
  • a pin is guided.
  • a corresponding force acts on the pin.
  • pen is broad and includes, for example, a sliding block.
  • the gate is preferably provided to connect a hinge lever with the linear guided sleeve. Also on this articulated lever can act a linear force. This is transmitted via the toggle lever on the sleeve.
  • the first spindle is drive-connected to a drive and that the movement device is drive-connected to a further drive.
  • the drive of the spindle is preferably designed as an electric motor or hydraulic motor.
  • the further drive of the moving device is preferably designed as a hydraulic cylinder or pneumatic cylinder.
  • the first spindle and the movement device are drive-connected via a transmission with a common drive. This gear is designed so that when closing the punch, first the force acts on the first spindle and subsequently the linearly movable sleeve is displaced via the movement device.
  • the pre-stroke unit has a hydraulically or pneumatically driven cylinder.
  • This cylinder is connected to the plunger and comprises a piston and a piston rod.
  • the power stroke unit has an engagement element.
  • This engagement element is used for direct power transmission to the piston rod or the piston.
  • a thread is formed between the engagement element and the piston or the piston rod. This thread is in particular a fine thread. This thread can be moved over a short distance but with high force of the piston.
  • the engagement element of the power stroke unit is preferably moved via an electric motor or hydraulic motor.
  • FIG. 1 shows a joining device according to the invention according to a first
  • Figure 2 shows a detail of the joining device according to the invention according to a second embodiment
  • Figure 3 shows a detail of the joining device according to the invention according to a third embodiment
  • Figures 4 and 5 schematically simplified views of a joining device according to a fourth embodiment.
  • the joining device 1 has a C-shaped carrier 4. At one end of the C-shaped support 4 is a stationary die 2. At the other end of the C-shaped support 4, a punch 3 is movably received. Between the punch 3 and the die 2, the objects to be joined are positioned.
  • the joining device 1 is used for example for clinching, punching or for setting rivets.
  • the Vorhubech 5 comprises a first spindle 8 and the working stroke unit 6 a second Spindle 9.
  • the two spindles 8, 9 are arranged one inside the other and one of the two spindles 8, 9 is connected directly to the punch 3.
  • a differential gear is provided between the two spindles 8, 9 and a drive 7, a differential gear is provided. This differential gear initially distributes the power of the drive 7 to the first spindle 8 to deliver the punch 3 quickly. Then the force of the drive 7 is transmitted to the second spindle 9.
  • FIG. 1 shows an X and Y direction.
  • the delivery of the punch 3 takes place against the die 2.
  • the Y direction is perpendicular to the X direction.
  • the drive 7 is designed as an electric motor or hydraulic motor.
  • FIGS. 2 and 3 show the joining device 1 according to the second embodiment. For the sake of clarity, only sections of the joining device 1 are shown in FIGS. 2 and 3.
  • the pre-stroke unit 5 has the first spindle 8. This first spindle 8 is connected directly to the punch 3.
  • the Hähubech 6 comprises a linearly movable sleeve 11.
