Description

The conveyer that is used for press
Technical field
The present invention relates to a kind of conveyer that is used for press as described in the preamble according to claim 1.
Background technology
Be used for generally including two clamp tracks that extend along the throughput direction of workpiece in the conveying device of multistation press conveying workpieces, described clamp track is also carried out additional transverse movement except that vertical and lifter motion, wherein the clamp track is provided with clamp members.For driving these clamp tracks, people adopt different electric drivers recently, and described electric driver has almost completely replaced the mechanical actuation device that is connected on the press drive unit commonly used in the past.
By the known a kind of device that is used for coming by a series of processing processing stations of press, simulator etc. conveying work pieces of DE 195 06 079 A1, described device has two delivery tracks that are parallel to each other spaced from each otherly and extend on throughput direction.Delivery track is provided with the receiving system that is used to treat conveying workpieces.Delivery track can move by means of the linear motor in the vertical direction and the level that are provided with in pairs jointly opposite to each other.Be used to provide the linear motor that is embodied as paired setting along the drive unit that moves of three axis of movements, wherein the linear motor that is oppositely arranged about the axis of press can drive control synchronously.The shortcoming of this scheme is the big quality of moving component.Drive unit especially for each axis of movement is provided with up and down stackedly, is carrying between moving period and must move together thus.This motion for whole system is disadvantageous.Other shortcoming is, employed linear motor only is suitable for use in the forming machine under certain condition, because particle is attracted by magnetic pull and therefore with the working face of other dirt particles Contamination Linear drive unit.This causes maintenance cost to improve.Because the use of linear guide apparatus also must be stood other shortcoming, for example since guiding device lubricate cause to the wearing and tearing of guiding device or to the pollution of equipment.In design, also lubricating pipe must be set.
DE 100 12 022 A1 have attempted to overcome these shortcomings.It discloses a kind of transmission drive unit, the guiding device that this transmission drive unit does not use the needs that are used for each motor element to exert to safeguard to the full extent.It proposes a kind of drive unit that comprises the movable hinge bar that is suspended.By using three-dimensional drive unit, set up a kind of " multiple spot suspension " mode, that is to say that the clamp track all is suspended on the hinge in the mode that limits on all three axis of movements, therefore can not use guiding device commonly used.At this advantageously, all hinge bars and connecting rod all are arranged on the top of workpiece transporting flat, make can be easily near instrument (mould) space and do not exist and cause and hinder the ground installation that disturbs.Particularly when using conveyer belt or depositing platform, this advantageous particularly.
The shortcoming of this layout is that the topology layout of drive unit and hinge bar needs very large space.Particularly the open and close of clamp track moves through the very large mechanism of the amplitude that comprises turning joint and hinge bar and transmits.This causes, and above-mentioned transmission drive unit must be installed in the column outside fully on by direction (through-passage direction).The clamp track must be so long thus, makes it outstanding from the column zone in both sides.This means big quality again, and this big quality must be moved together when the conveying motion and motion and use are compared more than the clamp track of weak point and be worsened.Because the clamp track is suspended on press column outside, suspension distance is bigger, and this causes the big deflection of clamp track.For reducing deflection, the clamp track must be equipped with bigger wall thickness.This causes adverse effect to motion again.
Another shortcoming that is caused by the big space requirement of above-mentioned transmission drive unit is, some that the confined space only can be provided for the user side used, and this conveyer is unavailable.
