Definitions

  • the invention relates to a stamping and embossing tool according to the preamble of claim 1.
  • Such stamping and embossing tools are used to connect two parts to be joined, preferably Sheets using a rivet.
  • Such rivets have a rivet head and a groove on the shaft
  • the two are placed on an anvil Joined parts are pressed together by a spring-loaded hold-down device, whereupon the rivet needle presses the rivet into the parts to be joined, and in the process punching slugs from the Parts to be punched out.
  • the rivet head With the further downward movement of the rivet needle the rivet head is pressed into the punched-out part of the upper part.
  • a stamp of the edge of the anvil's hole is printed in the lower part, the displaced material penetrating into the shaft groove.
  • the pressure exerted by the spring-loaded hold-down device is often not sufficient to press the two joining parts against one another without a gap, which is particularly the case with hard and thick sheet metal is the case.
  • the strength of the riveted joints is therefore differently.
  • the same disadvantage occurs when the parts to be joined are different Show tolerances. Since the movement of the ram is controlled away, must Thickness tolerances can be compensated for by adjusting the height of the anvil.
  • the task is to design the stamping and embossing tool so that it is flawless Rivet connection between the parts to be joined is achieved.
  • the stamping and embossing tool has a hydraulic cylinder 1, in which two pistons 2, 3 are guided.
  • the rivet needle 4 is connected to the upper piston 2, while with the lower piston 3, a press cylinder 5 is connected, which in Fig. 1st press ram, not shown.
  • With the upper piston 2 is still connected a hollow piston rod 6.
  • the piston 2 has bores 7, which the space 8th Connect between pistons 2, 3 to the inside of piston rod 6.
  • the cylinder 1 has a connection 9 which opens into the cylinder space above the piston 2.
  • the inside of the piston rod 6 is connected to a further connection 10, while the cylinder space below the piston 3 is connected to a third connection 11.
  • a first pressure cylinder 12 Connected to port 9 is a first pressure cylinder 12 with which another Printing cylinder 13 can be connected, with which in turn a third printing cylinder 14 is connectable.
  • the connection 10 is connected to an adjustable throttle 15, the is in turn connected to a variable-volume pressure chamber 16.
  • the sequence of operations is as follows:
  • the piston 17 of the pressure cylinder 14 is initially himself in his left position. Take the pistons 18 and 19 of the pressure cylinders 12, 13 their right position as shown. This creates a hydraulic connection from the impression cylinder 14 via the impression cylinder 13 and the impression cylinder 12 to Connection 9.
  • the throttle 15 is open, so that a direct connection between the Space 8, the holes 7, the hollow piston rod 6, the connection 10, the throttle 15th to the left side of the piston 20 of the pressure chamber 16. To the right side of the Piston 20 acts at a constant pressure.
  • the piston 2 has approached the piston 3 by a predetermined distance, which is greater than the length of the rivet, the pressure cylinder 12 is activated by Compressed air supply at port 23 of piston 18 is moved to the left. At this Movement, the connection between the cylinders 12, 13 is interrupted. From Pressure cylinder 12, oil is supplied to port 9 under high pressure. With Actuation of the pressure cylinder 12, the throttle 15 is activated, so that between the throttle resistor 10 and the pressure chamber 16 are built up. This throttle resistance is adjustable.
  • the piston 3 thus has a high resistance, but due to the throttle resistance adjustable pressure, which causes the ram 25 attached to the press cylinder 5 exerts a high hold-down force on the joining parts 24A, 24B, which is thus gap-free lie against each other, see position according to Fig. 3.
  • the rivet 29 of the Rivet needle 4 pressed through the joining parts 24A, 24B and the rivet head into the generated Bore of the upper joining part 24A, see position according to FIG. 4.
  • the pistons 17, 18, 19 are returned to their starting position.
  • the throttle 15 will be opened.
  • the oil pressure in the pressure chamber 16 separates the two pistons 2, 3 from one another.
  • a pressure is built up below the piston 3 via the connection 11, so that both pistons 2, 3 are returned to their starting position.
  • the hydraulic cylinder 1 is connected to the tool frame via a C-bracket 23 is.
  • the tool head comprises the rivet needle 4 and the ram 25, the one Has bore through which the rivet needle 4 is displaceable.
  • the ram 25 is attached to the press cylinder 5.
  • At the lower end of the rivet needle 4 is a Flanged valve body 30, the slide of the rivet 29 the lower end of the Rivet needle 4 feeds.
  • the press ram 25 has the function of a hold-down device.
  • the to each other connecting joining parts are designated with 24A and 24B. They are on anvil 26 on this anvil 26 is provided with a bore 27 which is formed by an embossing lip 28 is surrounded.
