Definitions

the invention relates to a feed device for the upper slide of a press, in particular a pottery press, a drive motor with a Feed spindle is connected, which is mounted in a casing tube, the Feed spindle is screwed through a spindle nut, which is in a relative is fixed axially adjustable piston tube to the jacket tube, and wherein Piston tube is mounted on the upper slide.
Known feed devices for the top slide of a press in particular a pottery press, have a single drive motor or hydraulic drive with larger forces to the upper slide connected to an upper mold Deliver the press to the associated sub-mold. It is desirable that Infeed of the upper mold until just before the lower mold with a relatively large one Feed speed to perform, and this feed movement just before Reach the bottom mold appropriately to reduce a defined squeeze and Perform impression movement. The return movement of the upper mold after Carrying out the pressing process in the starting or basic position can then again with a correspondingly high speed. This sequence of movements due to the known feed devices of the type mentioned a corresponding drive control for a single drive motor.
a feed device of the type mentioned for an upper slide Press, wherein a drive motor is connected to a feed spindle, which in a jacket tube is mounted, is known from JP 6-18 25 99 A.
the Feed spindle is screwed through a spindle nut, which is in a relative to the jacket tube axially adjustable piston tube is fixed.
the piston tube is attached to the top slide of the press.
a feed device for a press is known two drive motors with different speeds and different Has torques, the second drive motor relative to a spindle nut rotated to form a casing tube.
the invention has for its object a feed device of the beginning to create the type with which at a relatively simple constructive Structure of an exact infeed movement of the upper form or the upper slide of the Press for the lower mold with a precisely controlled one afterwards slowed pressure and impression movement as well as a fast Return movement to the initial or basic position of the upper mold is possible, with a large distance of the upper form or the upper slide between its retracted starting or basic position and its extended impression position is realizable.
This task is performed in a feed device of the type mentioned solved according to the invention in that the connected to the feed spindle Drive motor a first drive motor of high speed and low torque is that the piston tube mounted on the upper slide with a second Drive motor is connected to a lower speed and a higher Torque has as the first drive motor that the spindle nut in the Upper carriage distal end portion of the piston tube is fixed and that of the Spindle nut axially spaced one at the associated piston tube end Stripping device forming stripper is attached.
the first high speed, low torque drive motor is for Rapid movement of the top slide and thus that attached to the top slide Upper mold towards lower mold provided.
Such high speed drive motors and low torque i.e. correspondingly small drive power reasonably priced.
the first drive motor during the Rapid movement of the top slide rotates the feed spindle, see above that the spindle nut is related to the local press-resistant jacket tube axially adjusted becomes.
This rapid movement of the upper slide with the upper mold towards the lower mold can be supported by the second drive motor if simultaneously with the The feed spindle is driven by the first drive motor and the spindle nut is also driven by means of the second drive motor via the piston tube. Short the first drive motor is switched off before reaching the lower mold.
the further one Feed movement i.e. the squeezing movement now takes place only with the help of second drive motor.
This squeezing movement follows with the help of the second drive motor an imprint movement of the Upper form, i.e. of the top slide of the press.
the return movement of the upper slide and thus the upper shape into the initial or basic position is then raised again with the help of the first drive motor Speed and low torque.
This return movement can also the second drive motor are supported.
the first drive motor is switched off. Will the Retraction movement of the upper mold supported by the second drive motor, so also becomes the second drive motor when the starting or basic position is reached switched off.
the feed device for structurally simple compensation of dimensional misalignments the feed device according to the invention it is preferred if the Feed spindle in the casing tube by means of one on the one removed from the top slide End section provided self-aligning ball bearing is mounted and / or if that Piston tube is mounted on the upper slide by means of a second self-aligning ball bearing.
the first drive motor is a rapid traverse servo drive motor is.
the second Drive motor is a slow speed servo drive motor.
the feed spindle can be formed by a ball screw.
the first Drive motor with the end section removed from the upper slide Feed spindle is connected by means of a self-locking screw gear.
This screw gear can be a double screw gear.
the end position of the last-mentioned feed or squeeze movement can precisely defined by a limit stop provided on the press his.
the second drive motor switched.
the upper mold moves to generate the Freely programmable with the help of the second drive device from the lower mold.
the second drive motor can the top slide adjacent end portion of the piston tube and associated with the piston tube be connected by means of a gear transmission.
this Gear transmission gear it is advantageously possible that the second Drive device the mentioned feed i.e. Squeezing movement Torque limited generated by the gear transmission.
the feed device according to the invention has the very considerable advantage that that very high pressures with high performance purely mechanical are realizable.
FIG. 1 shows a front view of a press 10 with a frame 12.
the frame 12 has a base plate 14 and guide columns 16 which extend from the base plate 14 stand vertically upwards.
An upper slide 18 is located on the guide columns 16 guided vertically.
Position transducers 20 and 22 are provided on the guide columns 16, which with Interact sensor elements 24 and 26, which are provided on the upper slide 18 are.
the starting or basic position of the Upper carriage 18 and through the position encoder 22 is the squeeze and impression position of the upper slide 18 or the upper mold attached to the upper slide 18 28 defined.
a lower mold is axially aligned with the upper mold 28 30 provided on the frame 12 of the press 10.
the lower mold 30, for example, defines the outer contour of one Clay pot and the top mold 28 defines the inner contour of the clay pot.
other clay objects or Objects can be made from other materials.
a feed device 32 To drive the upper slide 18 with the upper mold 28 along the guide columns 16 of the frame 12 of the press 10 is a feed device 32, the one frame-fixed casing tube 34 and an axially in relation to the frame-fixed casing tube 34 adjustable piston tube 36.
the casing tube 34 has one of Upper carriage 18 removed end section 38, on which in the casing tube 34 Self-aligning ball bearing 40 is provided.
the self-aligning ball bearing 40 is used for storage of one end section 42 of a feed spindle 44 of the feed device 32.
the end section 42 of the feed spindle 44 is connected via a screw gear 46 a first drive motor 48 operatively connected.
the helical gear 46 acts it is expediently a self-locking double screw gear.
At the first drive motor 48 is preferably a rapid traverse servo drive motor high speed and low torque, i.e. relatively smaller Power.
the feed spindle 44 is screwed through a spindle nut 50 which in Piston tube 36 is fixed to its end section 52 remote from the upper slide.
the piston tube 36 is with its second end portion 54 by means of a second Self-aligning ball bearing 56 rotatably mounted on the upper slide 18.
the piston tube 36 is connected to a second drive motor 58 by means of a Gear transmission 60 connected to the second end portion 54 of the Piston tube 36 is provided.
the second drive motor 58 is concerned a slow speed servo drive motor, i.e. lower by a drive motor Speed and high torque.
FIGS. 2 and 3 In Figure 2, the feed device 32 is in their extended position and in Figure 3 in their retracted position shown.
the reference numeral 70 denotes a drive motor in FIG Stroke limitation of the upper slide 18 and thus to limit the stroke of the upper mold 28 is provided.
