Abstract
The press (1) has runner rails on which transverse beams with suction pads (2) are arranged to pick up and transport the metal parts directly or via carriages. A horizontal movement of the beams results via a mechanical curve (3) drive with pushing levers (4), coupled to the press drive. Vertical movement of the beams is caused by an electric drive (5). The mechanical horizontal movement of the beams is at the same time superimposed with a variably controlled vertical movement and a pivotal movement about the longitudinal axis of the beam, caused by an electronically programmable electric drive. The electronically controlled vertical and/or pivotal movement of the beam is dependent on the geometry of the workpiece in the press. Independent claims also cover a conversion apparatus for the press.
Description
Technical field
The present invention relates to be used to control the method for large piece stage press driving device and the equipment of implementing the method with aspirator beam conveyer.
Background technology
Large piece stage press is used for the large-scale metal sheet that the production auto industry is used, and for example makes roof, body bottom part or large scale sidewall paneling by metal forming.The sheet metal body transmits by a plurality of processing stations in manufacture process, and workpiece is carried out further forming process respectively at these stations.The transmission of workpiece is carried out by means of transposer, and the two-dimentional aspirator beam that people divide into the space with this transmission transmits or three-dimensional gripping apparatus rail transmission.
Under the situation that the aspirator beam transmits, the movement locus of aspirator beam is by horizontal movement and move both vertically and cause.Because it is little and because acceleration is big, so these motions produce (DE 3824058C1) by means of the cam drive of machinery usually from the safe distance of workpiece.The level of pure machinery and the shortcoming that exists that moves both vertically are that the motion process that transmits track can not or may change hardly.Can in limited range, change lift by changing the lever radius that transmits in the lever system in case of necessity.
In order to make flat large tracts of land workpiece,, only need have the transmission cam of little lift, so that this flat piece is proposed from counterdie as roof.In this case, between lifter motion and feed motion, can carry out big overlappingly, make the acceleration of workpiece can keep very lowly.By contrast, when making dark cliff spare promote with send between can only implement less or overlapping without any motion in case of necessity because workpiece must at first leave by the whole lifts ability without collisions that promote from mould.In the cycle time that remains on forcing press, require just that workpiece has big acceleration when feed motion.
For overcoming above-mentioned shortcoming, existing people's suggestion is designed to lift cam with feed motion irrelevant, in this case lift and shift out angle that is lifter motion and feed motion and can change.Known by EP 0754509 A1, horizontal movement drives by means of the cam mechanism of machinery, implements by means of the electric driver of watching eye control and move both vertically.In this case, lift and with respect to the motion angle at press crankshaft angle and thereby the movement locus of aspirator beam just can change.Based on mechanically operated horizontal movement in the prior art of quoting, so the aspirator beam is preferably in when tup falls and also can shifts out from mould forcibly, so that the security of increase anticollision when the electric cam drive unit that is used for moving up and down takes place to control by mistake.
The shortcoming that exists in the known device by EP 0754509 is that the freedom of motion of workpiece only promotes drive unit by means of electronics and improves.Though the known system that rotatablely moves that workpiece is possible implements (DE 4110215) by mechanical actuation device by means of the cam driving gear of longitudinal rod mechanism and controlled pressure machine.But still there is shortcoming in it, and its movement locus can only have change in a small amount.By the known guiding mechanism of directly on the conveyer frames of aspirator beam, also establishing cam control of EP 0499901, so that implement aspirator beam rotatablely moving to a certain degree.The control cam that this also requires to change machinery rotatablely moves with change.
At last, EP 0 818 254 A2 disclose the design of a kind of crossbeam or aspirator beam, and its deflection is implemented by means of servo motor.Stipulate that wherein every aspirator beam directly installs the servo motor of at least one belt driver.
Summary of the invention
