Definitions

  • the subject of this invention is a method for operating a press or a stamping machine, in which a ram is driven in an oscillating manner by a drive via an eccentric shaft and at least one connecting rod, the at least one connecting rod being rotatably mounted on the eccentric shaft at one end and at the other End is connected to the plunger.
  • Such presses have been known for a long time.
  • the ram moves back and forth between a lower and an upper dead center.
  • the pressing or punching force is fed directly into the ram via one or usually several connecting rods (2- or 4-point press).
  • Adjustment options are also provided to adjust the stroke. This is usually done via an eccentric bushing.
  • the position of the tappet can also be set using a ball spindle at the lower end of the connecting rod (tappet adjustment).
  • the U.S. 3,552,182 A , U.S. 3,005,404 A and DE 35 07 327 A1 describe presses with double-acting hydraulic cylinders in the connecting rod shaft.
  • the distance between the ram and the workpiece can be adjusted via these hydraulic cylinders, and the hydraulic cylinders also serve as overload protection.
  • the JP H03 238200 A discloses a single-acting hydraulic cylinder which is controlled by means of a magnetic switch.
  • the US 2014/208964 A1 discloses a press that can be vibrated.
  • the ram is divided into two parts, so that it consists of a main ram and a sub-ram.
  • the main slide and the lower slide form a cylinder-piston mechanism.
  • the invention is based on the object of providing a method for operating a press or an automatic punching machine, in which the punching or reshaping process is improved.
  • the double-acting hydraulic cylinder according to the invention also makes work on the open tool particularly easier.
  • the ram is moved to the top dead center with the help of the eccentric drive and then the lift stroke is activated via the double-acting hydraulic cylinder.
  • the lift lift for example, has an opening path of 140 mm. With a press stroke of 160 mm, a maximum opening path of 300 mm can be achieved. This means that the pressing tool is easily accessible for visual checks or for work on it (e.g. grinding work).
  • the double-acting hydraulic cylinder can be used to increase the overload travel. This also guarantees more efficient tool protection.
  • the hydraulic cylinder can also have the function of a
  • the double-acting cylinder can also be used to implement a quick lift stroke of the ram or, if necessary, to act as an overload protection device when a check is required or when work is being carried out on the tool.
  • the press is operated in such a way that the working stroke of the press is carried out only by the double-acting cylinder or cylinders, the hydraulic cylinder being operated in a vibrating manner.
  • the upper end of the connecting rod is in the upper (0 ° position) or lower dead center (180 ° position) so that no rotational forces are introduced into the eccentric shaft. If there are several connecting rods, all double-acting cylinders in the respective connecting rods are operated to vibrate.
  • FIG. 1 shows an example of a press 1 with a press table 2, side stands 3 and a head piece 4.
  • the eccentric shaft 5 is rotatably mounted in the head piece 4.
  • a drive 6 drives the eccentric shaft 5 via the drive belt 7 and the flywheel 8.
  • two eccentric bushings 32 are arranged, on each of which the upper end 30 of the connecting rod 9 is rotatably mounted via a roller bearing 14.
  • the upper end 30 of the connecting rod 9 is composed of two halves 15, 16 screwed together.
  • the lower ends 17 of the two connecting rods 9 are connected to the tappet 10.
  • the upper tool part 12, which can be pressed against the lower tool part 11 during operation, is fastened to the ram 10.
  • the plunger 10 is guided along the side stand 3 via the roller guide 13.
  • FIG. 2 a connecting rod 9 according to the invention is shown in detail.
  • a double-acting hydraulic cylinder 27 is arranged in the connecting rod shaft 31 here.
  • a piston 22 is arranged within the cylinder 25. Hydraulic fluid can be applied to the pressure chamber 23 or the annular chamber 28 via the lines 24 or 26 and the piston 22 can thus be raised or lowered become.
  • the vibrating movement of the piston 22 is realized by the rapid alternating application of pressure to the pressure chamber 23 and the annular chamber 28.
  • FIG. 3 now shows a functional diagram.
  • the plunger 10 can be driven to oscillate in a known manner via the rotating eccentric shaft 5. This enables a ram stroke A to be implemented.
  • the stroke B can also be realized.
  • the vibrating actuation of the hydraulic cylinder 27 takes place via the magnetic switch 29.
  • the magnetic switch 29 alternately acts on the upper pressure chamber 23 or the lower annular chamber 28 with the hydraulic fluid, so that the piston 22 vibrates, for example at a frequency of 20 Hz.
  • the upper pressure chamber 23 is currently being filled with hydraulic fluid coming from the supply line P via the line 24.
  • the lower annular space 28 is emptied into a tank T via the line 26.
  • the piston 22 moves the plunger 10 down here. Due to the double-acting hydraulic cylinder 27, the tappet 10 can thus be raised and lowered very quickly and thus operate vibrating.
  • the working stroke can be carried out jointly by the eccentric drive and the double-acting hydraulic cylinder 27.
  • the eccentric drive moves the vibrating hydraulic cylinder 27 downwards, so that the plunger 10 moves downwards in a vibrating manner.
  • the working stroke can also only be realized by the vibrating double-acting hydraulic cylinder 27, with the pressure chamber 23 being supplied in small jolts to the pressure chamber 23 during a working stroke than is subsequently discharged, so that a linear downward movement is superimposed on the vibrating movement of the piston.
