Pressing - More than just building up pressure

The presses belong to the
field of manufacturing technology. In addition to the “material separating”
manufacturing process, there is also the “material forming” manufacturing
process for presses. The combination options and the definitions of the presses
are therefore complex and varied.
A press is a machine tool
that is able to carry out several processing steps. The following processes are
possible: cutting, punching, bending, spotting and deep drawing. In sheet metal
processing, punching and bending machines are also considered to be presses in
the broadest sense.
Presses are usually
designed in a vertical manner. The main components of a press are the press
table, press frame, press tool and press ram driven by hydraulic cylinders,
toggle levers or spindles. Simple presses or workshop presses are characterized
by a single column or O-frame construction.
The presses are available
in a wide variety of sizes and capacities for processing large and small
workpieces.
An extension of the
flexibility and automation is possible with a press with a semi or fully
automatic tool change. Depending on the size and weight of the tool, tool
changing trolleys are used. In the next step, it is also possible to link
presses with handling units in between. These links are also called production
lines. There are few limits to automated production.
At tramao, we have decided
on the following categorization for the metalworking machines sector:
• 4-column presses
• press brakes
• Double column presses
• Single column presses
• Eccentric presses
• Hydraulic presses
• Wedge presses
• Knee lever presses
• Manual presses
• Pneumatic presses
• Embossing presses
• Straightening presses
• Forging presses
• Cutting presses
• Servo presses
• Other presses
• Screw presses
• Stamping presses
• Extrusion
• Spotting presses
• Workshop presses
• Drawing presses
But also in the area of
printing machines we have created a category for presses on tramao:
• Extraction presses
• Boston crucible presses
• Printing presses
• Fischbach presses
• Gally crucible press
• Gordon crucible presses
• Hand presses
• Knee lever presses
• Copy presses
• Liberty crucible presses
• Rapid pressing
• Rocking cylinder presses
• Other presses
• Stanhope presses
• Platen presses
• Transfer presses
• Vertical presses
• Cylinder presses
The variety of presses in
the paper and printing sector differs only slightly from the variety in the
metal sector.
A press can also belong to
several categories. This is why it is possible on tramao.de to assign more than
just one category to a machine. However, a maximum of three categories per
press are possible.
Presses - Versatile areas of application
There are many classic
areas of application for presses. In small workshops, for example, these are
required for pressing in bearings as well as in complex industrial production
lines.
There is no typical
industry in which presses are used. The automotive industry needs these
machines just like the wood industry or special machine construction.
Technology also has few limits. Presses are required in the manufacture of
plywood or chipboard or in the manufacture of pots in the food industry.
Composite materials are also a typical example of how parts are pressed
together with the use of heat. As a last example, we mention the scrap presses
from the recycling sector, which turn a car into a handy metal block in a very
short time.
How can a company choose
the right press from the multitude of options? This is not always easy and
depends on a large number of parameters. The complexity and the number of
pieces of the workpiece to be produced play an important role here. The risk
and financial investment can be minimized by purchasing a used press. The
robustness of the older used presses is also often valued. Another reason for
buying a car can be the ease of repair.
tramao offers you a large
selection of used presses. You will also find the right service companies for
repairs and spare parts procurement on tramao.
On tramao you will also
find a wide range of machine accessories for presses such as tool trolleys,
machine feet, clamping devices, lubricant systems and much more.
Not to be forgotten is our
range of tools. Should you decide to buy a
used press, you will find a large selection of well-known manufacturers such as
AIDA, Feintool, Hiller, Ageo, Müller-Weingarten, HSM or Heidelberg on tramao.
