摘要:
The invention relates to an apparatus for working, in particular for working without machining, for example for separating and/or forming, a web of material, having a plurality of individual tools for different manners of working the web of material with designated workpieces temporarily held therein, and having a machine direction along which the web of material with the designated workpieces and the plurality of individual tools can be moved incrementally relative to one another in such a way that the web of material can be worked multiple times within one work cycle by means of the plurality of individual tools, wherein the individual tools are designed as individual modules which can be fixed to one another to form an individual module cluster, but can be detached as well.

A method for operating a mechanical press including at least one electric drive motor, a drive control for controlling the at least one motor, a ram, a mechanical element for translating rotational motion of the at least one motor to linear motion of the ram in a first rotation direction, into a linear motion of the ram arranged to be lowered and raised along a linear path for operating the press to carry out a press cycle including a pressing part and one or more non-pressing parts of the press cycle, and by providing a control output to the drive control such that the speed of the at least one drive motor is varied during at least one pressing or non-pressing part of the press cycle. The press may be reversed between production cycles. Also press and system including a such press.

There are provided a device and a method capable of reducing a press angle control error caused by a press load variation and of preventing a press load variation of one press machine from acting on the other press machine.The device includes: a reference value output unit 25 which outputs a press angle reference value; and a press angle detection unit 27, a speed command unit 29, and a driving unit 31 which are provided for each press machine. The press angle detection unit 27 detects a press angle of the corresponding press machine and outputs a press angle detection value. The speed command unit 39 outputs a command speed value of a motor of the corresponding press machine on the basis of the press angle reference value and the press angle detection value. The driving unit 31 controls a speed of the motor of the corresponding press machine on the basis of the command speed value. The device further includes a correction unit 33 which corrects the press angle reference value or the command speed value so that a difference between the press angle reference value and the press angle is within a predetermined range.
摘要:
An press line including at least one mechanical press with at least one electric drive motor, a ram, a mechanical unit for operating the press, and one other device or auxiliary production device. The press is arranged so that the speed of the at least one said drive motor may be varied during at least one pressing or non-pressing part of a press cycle. Improved operating characteristics and optimised energy use and cycle times are obtained by controlling the speed of the motor and synchronizing a movement of the press to a movement or position of at least other device, loader or other press. A system includes the press. A computer program controlls the press line.
摘要:
Methods and systems to drive rotary presses are described. In one described example, a rotary press system includes a first rotary press and a second rotary press adjacent to the first rotary press. The first and the second rotary presses are to receive a strip of material. A drive member is operatively coupled to the first and the second rotary presses and a motor coupled to the drive member rotates the drive member to cause the first and second rotary presses to process the strip material.
摘要:
A transfer press having a plurality of slides, and comprising slide drives being drive sources provided every slide, and a control device for controlling the slide drives to synchronously drive and/or singly drive the slides individually.

摘要:
A method for synchronizing a first machine of a manufacturing process section arranged to carry out a production cycle including a working part and a non-working part. The first machine is operated in conjunction with at least one second machine. The first machine carries out a process during the working part of the cycle on a workpiece that is loaded into and/or unloaded out of the first machine by the at least one second machine during the non-working part of each process cycle. Also, a system for carrying out the method and a computer program.

摘要:
A controller for a work transfer system, capable of performing precise positioning of feed bars during sole driving of the transfer system and simplified in structure to contribute to savings in installation space and cost. The controller has a cam angle detector mounted on a cam shaft for feed cams and controls servo motors for respective lift bars according to information which is related to cam angle of the feed cams detected by the cam angle detector and looked up in a motion table set by a transfer controlling PLC serving as a motion table setting means.
