Description

modupress Press-in devices

modupress Press-in devices
Modular system as press-in device
Thanks to the modular design, the functions of the control as well as mechanical components can be easily exchanged or retrofitted.

Application
modupress Press-in devices are preferably used in assembly processes for the production of longitudinal pressed joints, riveted joints as well as for pressing out and testing of components.

 Principal use
• Drive technology, gears box assembly
• Couplings, cardan shafts
• Compressors, pumps, hydraulic elements
• Industrial fittings
• Mechanical engineering
• Components for construction and agricultural machinery
• Electronics

Operation
For safety reasons, the press-in device is equipped with a two-hand operation. This has a divided design (two separate push-buttons) to allow workpiece feeding from the front.
Alternatively, it is also possible to provide safety light grids or a protective covering. In such applications, function triggering is made by a push-button.

Versions
• hydraulic or electrical drive
• portal design or C-frame design
• 3 control variants

Description
The base frame is designed as a working table.
Below the table plate there is the electric control and close to the drive the power unit which control the hydraulic press-in cylinder at the portal or the C-frame.
The steel base plate of the frame is installed flush with the table plate in the working table, so that the working surface is plane and edges are avoided.
On the base plate any workpiece carriers such as sliding tables can be mounted.
The piston rod of the press-in cylinder is equipped with a quick-changing device, at which the press-in tools can be mounted. This can optionally be replaced by other tool holders.

Control variants

Control variant 1: Rapid/creep speed
• stroke measurement
• touch panel, 4 inch

Functional description - normal operation (press-in operation)
After function triggering, the press-in cylinder extends first at rapid speed. After reaching the defined switching point, the speed will be reduced to creep speed.

Join to force:
After reaching the set maximum force and the subsequent hold time, the press-in cylinder retracts to the defined return position.

Join to position:
After reaching the set position, the press-in cylinder retracts to the defined return position.

Setting mode
When selecting "setting mode" at the touch panel, the press-in cylinder can be extended or retracted by manual control. Thus, it is for example possible to approach workpiece-specific points, read positions to enter these as parameters.
The press-in cylinder moves with touch control (i.e. only when the push-buttons are pressed) and only in creep speed.

Control variant 2: Rapid/creep speed with force/stroke monitoring
• stroke measurement
• force measurement
• touch panel, 7 inch

Functional description - normal operation (press-in operation)
as control variant 1, however with the following additional functions
By means of the touch panel for one of the possible 100 data records the desired press-in forces with the associated stroke points and their admissible limit values are entered and represented on the screen in the form of force/stroke windows (figure 3).
The press-in force is permanently measured with the force transducer and the stroke of the press-in cylinder with the stroke measuring system. At any preset force/stroke point, the measured values are compared with the admissible limit values. If one or several measured values are outside the admissible limit values, a NIO error message appears immediately (NIO = not in order).
In order to make a new pressing, the error message at the touch panel must be reset first. If all the measurements are within the set limit, an IO message appears immediately and the next pressing can be effected (IO = in order).

A data record consists of (see Graphical representation of the press-in process):
• position - off-position (return stroke limitation)
• position - switching rapid/creep speed
• max. force 
• min. force
• max. stroke
• min. stroke
For the data output of the specified and measured values, the interfaces for Ethernet and SD card are available.


Control variant 3: Creep/rapid speed control with programming of the operating time (for ECO press-in devices)
• time panel

Functional description - normal operation (press-in operation)
By operating the two mushroom push-buttons at the two-hand operating panel at the same time, the press-in cylinder extends (starting from the off-position). As soon as the first adjusted time mark (s) is obtained, or the time (s) has passed, the press-in cylinder switches automatically from rapid speed to creep speed.
After reaching the set maximum force, the press-in cylinder retracts to the off-position that is adjustable by the time. The preset maximum force is maintained for 1s in the lowest press-in position in order to safely terminate the joining process.
If the two-hand operation is released in an intermediate position, the press-in cylinder remains in this position. When pressing the push-buttons again, the press-in cylinder moves in rapid speed to the off-position. 
Only after reaching the off-position, the press-in cylinder can be extended again.
