Definitions
- the invention relates to a device for actuating a ram in a lifting or tensioning device, in particular for folding sheet metal in automobile construction, wherein a ram guided and drivable in a base frame with a folding bed lying thereon presses the sheet metal to be folded against fixed folding tools.
- the object of the invention is to dispense with hydraulic or pneumatic systems for generating and transmitting the necessary force.
- the tappet is supported with its side facing away from the tool on at least one wedge surface which is adjustable by an electric motor.
- a wedge having the wedge surface can be guided on the base frame and is adjustable by an electric motor.
- the wedge is preferably adjustable essentially orthogonally to the working direction of the ram.
- a spindle nut for a spindle guided therein and driven by an electric motor is arranged on the wedge. When the spindle rotates, the wedge is adjusted and the ram is raised or lowered. In a space-saving arrangement, the spindle nut is accommodated in a recess in the wedge.
- the recess is preferably a stepped bore, the portion of which with a larger diameter receives the spindle nut and the portion of which with a smaller diameter can move the end of the spindle.
- the spindle nut preferably has a ball screw thread.
- the spindle can be connected to an electric motor via a coupling.
- the electric motor is preferably converter-operated.
- a transmission can expediently be connected between the electric motor and the clutch.
- the spindle On the motor side, the spindle can be guided in an axial spherical roller bearing.
- the device which is preferably referred to as an electromechanical lifting unit, can be used, inter alia, in the fields of clamping technology, folding or flanging technology and also in special areas of conveyor technology.
- the invention is explained in more detail, for example, with the aid of the attached FIGS. 1 to 3. Show it:
- Fig. 1 shows schematically and partially a device for folding
- Fig. 2 shows another embodiment using two oppositely displaceable wedges (18, 19) in the lower one
- FIG. 3 shows the embodiment of FIG. 2 in the upper opinion of the wedge (19).
- the plunger 1 shows a plunger 1 which can be moved vertically up and down and which carries a folding bed 2 on the top side for the body panels to be folded. Fixed folding tools (not shown) are located above the folding bed 2.
- the plunger 1 is guided in a base frame 3 between sliding plates 4. Below the plunger 1 there is a horizontally adjustable wedge 5 which is guided on slide plates 6 arranged on the base frame 3.
- the plunger 1 is supported with a sliding block 8 on an inclined wedge surface 7 facing the plunger 1.
- a spindle nut 10 is inserted axially immovably and non-rotatably.
- the spindle nut 10 is formed in the illustrated embodiment as a ball screw thread.
- a spindle 11 is guided in the spindle nut 10, the free end of which can move into the section with the smaller diameter of the recess 9.
- the other end of the spindle 11 is guided in an axial spherical roller bearing 12 which is arranged in a bearing housing 13 connected to the base frame 3.
- a bearing housing 13 connected to the base frame 3.
- Coupling 14 the output of which is connected to the spindle 11 and the input of which is connected to the output shaft of a gear 15, which in turn can be driven by an inverter-controlled electric motor 16.
- the spindle 11 With the corresponding direction of rotation of the electric motor 16, the spindle 11 is set in rotation after the clutch 14 has been switched on. Via the implementation in the spindle nut 10, the wedge 5 moves in the horizontal direction and thereby moves the plunger 1 in the vertical direction.
- a left lower wedge 17 and a right lower wedge 18 with oppositely inclined wedge surfaces 7 can be moved in opposite directions with the aid of a common screw drive 20 with left and right hand threads.
- the screw drive 20 is driven by a common electric motor 16 via the coupling 14 and has bearings 23 and 24 at the end.
- the two wedges 17, 18 are moved towards one another simultaneously with the aid of the screw drive 20, the associated wedge surfaces 7 of the Slide wedges 17, 18 on the wedge surfaces 25 of the upper wedge 19 and thus lift the plunger 1.
- the wedges 17, 18 are moved apart again and the plunger 1 is thus lowered.
