Definitions

  • the invention relates to a device for controlling a Lifting movement of a riveting machine with one rivet head and one Rivet stamp for making a rivet with a Head height.
  • a bolt becomes an easily deformable one Material for the insoluble form and partly also understood non-positive connection of components.
  • He consists of a set head of different shapes and one solid, hollow or riveted shank.
  • the rivet shank is punched or drilled and deburred rivet holes and depending on the type and Accessibility of the rivet reshaped.
  • a full rivet is on existing setting head with a counterholder held and the free end of the shaft by pressure or Impact directly or with the help of a head stamp (Döpper) indirectly deformed into a closing head.
  • a corresponding device is for example from DE-PS 28 48 917 known.
  • the present invention has for its object a Develop device of the type mentioned above, with the a constant closing head height within one predetermined small tolerance margin maintained becomes.
  • the riveting die has a Device for switching the stroke movement of the rivet head assigned after reaching the predetermined closing head height is.
  • the device according to the invention is a so-called rivet stroke limit switch device, in which the Determination and setting of riveting time and rivet spindle stroke the riveting machine is unnecessary. Given the air pressure (Rivet spindle force) and required closing head height always worked automatically with the shortest possible riveting time.
  • the device preferably has a probe arm which is connected to at least one reference tip for placement on a reference surface is provided.
  • This reference peak should be in a vertical distance from a pressure point of the rivet punch be arranged, which is greater than the closing head height is.
  • the switch pin is the probe arm assigned.
  • the probe arm and switching pin are vertical together movable, for example fixed on a lifting slide, which is guided vertically in corresponding guides. This can be ball bearing roller or the like guides act.
  • the tours themselves are subordinate Significance, why all of the present inventive concept possible tours should be included.
  • the switch pin opposite the contact pin or the contact pin opposite the switching pin also be arranged to be vertically movable.
  • the contact pin opposite the switching pin arranged movably. This can for example the contact pin or a slide on which the contact pin is arranged in the same, but then extended guides can be arranged, such as the switch pin or the lifting slide for the probe arm.
  • the adjusting rod is a rotary knob with a corresponding scaling is assigned. Will on the Turned the knob, the sled moves along the Adjustment rod up or down.
  • the riveting stroke limit switch device acts dynamically measuring and compensating machine and workpiece errors during the riveting process. Degree of deformation and The strain on the rivet material remains constant under all conditions and therefore also the properties the riveted joint.
  • Riveting machine any, even those that have been on the market so far Riveting machine can be retrofitted. Furthermore, the rivet position indifferent in the room because the device according to the invention always follows with the rivet head, regardless of whether it is vertical from top to bottom, bottom to top or horizontally emotional.
  • a rivet head 1 indicated, from which a rivet punch 2 protrudes.
  • This rivet punch 2 is in relation to a rivet axis 3 inclined, for example in the Radial riveting machines common today are the riveting dies 2 swing spatially to improve riveting. Of course this rivet punch could also be in the rivet axis 3 run.
  • the rivet head 1 is an inventive device E for Switching the lifting movement of the rivet head 1 in the y direction assigned, this device E via a connecting element 4 is connected to the rivet head 1.
  • This Device E has a support plate 5 on which a Probe arm 6 is arranged.
  • This probe arm 6 is opposite the support plate 5 in the direction of the double arrow 7 movable arranged, with a corresponding lifting carriage 8 in vertical guides, not shown, but commercially available is movable along the support plate 5.
  • the scanning arm 6 protrudes approximately horizontally from the lifting slide 8 from where it has a conical opening 9 at the end, which at least partially surrounds the rivet punch 2. At the edge, this opening 9 has at least one Reference tip 10.
  • the probe arm 6 is over any fastening means connected to the lifting carriage 8.
  • a switching pin 11 protrudes from the lifting carriage 8 and also together with the lifting carriage 8 vertically in the direction of the double arrow 7 is movable. With his movement the switching pin 11 meets a contact pin 12 which again from another also vertically in the direction of the double arrow 7 adjustable carriage 13 protrudes.
  • This carriage 13 is also preferred in FIG guided vertical guides shown, these Guides the continuation of the guides for the lifting carriage 8 can be.
  • the leadership is in the present embodiment marked only schematically with the reference number 14.
  • the carriage 13 is also a spindle thread 15 an adjusting rod 16 placed and upon rotation of the Adjusting rod 16 vertically adjustable.
  • the adjustment rod 16 rotates in a holding plate 17, which with the support plate 5 connected is.
  • a turn is made using a rotary knob 18, which also has a scale 19, via the one Distance x between the contact pin 12 and the switching pin 11 can be set.
  • This value x corresponds to that Distance of a pressure point 20 of the end face 21 from the Reference tip 10 of the probe arm 6 minus one desired closing head height h of a closing head 22 a rivet 23 with which in the present embodiment two plate-shaped workpieces 24 and 25 be connected to each other.
  • the workpieces 24 and 25 for clarity arranged relatively far from the probe arm 6, in In practice, the probe arm 6 will be relatively close above of the workpieces 24 and 25 are.
  • the closing head height h is closed measure and the difference to the desired target size on Readjust rotary knob 18.
  • the scaling is preferred 0.05 mm per division, so that the setting in very small steps can be taken.
