Vertical press

Vertical presses are press machines with a vertical direction of action of the slide movement. They are used in the areas of waste disposal, letterpress printing, metal forming and wine press technology.

Waste disposal

When unpacking, repacking and picking of goods in trading and production companies, large quantities of cardboard are generated , which take up a lot of space and take up a lot of time for disposal . Hydraulic horizontal and vertical baling presses with various pressures are used for the environmentally friendly recycling of residual / valuable materials.

Letterpress

As a vertical press is defined as a letterpress printing machine ( high pressure ), more precisely a high-speed press , in which the foundation ( closing frame with the set of lead type, lead lines, lines, graphic and image clichés) is vertical. This design only allows smaller print formats than the more widely used high-speed press types of stop cylinder, single-turn cylinder, two-turn cylinder and swing cylinder press, where the foundation is horizontal in the machine and can therefore be very large and heavy. The machine size and the possible print formats of the vertical press are comparable to those of the platen printing machines . Vertical presses were mainly manufactured by the Miehle company. They were and are to be found in the USA and in Europe in Switzerland, but today they are mostly only used for hobby purposes or in museums.

Forming technology

In forming technology , both hydraulic and mechanical presses are used in vertical and horizontal construction. The required press sizes are determined for hydraulic and mechanical presses on the basis of the part geometry and the workpiece material as well as the manufacturing process derived from this. In the vertical design, the hydraulic components and oil containers are usually housed in the head piece. The maintenance platform enables easily accessible access to the units. The stand design is usually designed in a curved monoblock or panel construction. In the event of space problems or to reduce noise, the pumps and motors can also be installed in the foundation or in a separate room. The vertical hydraulic presses are mainly used for cold forming; however, its use for hot forming is not unusual under certain conditions. Extreme parts in particular (weights over 5 kg) are relatively often hot-formed on hydraulic presses.

Both vertical and horizontal designs are used in mechanical presses, the difference being the production quantities, which are higher with horizontal presses (3600 to 9000 / h) than with vertical systems (1800 to 3600 / h).

Thanks to their thick pomace cake , the vertical vintners , which were still in use before the 1950s, carried out extensive pre-clarification of the musts themselves , which were displaced with the use of horizontal vintners. In today's cellar technology , horizontal parenting has prevailed in larger companies. For pressing the mash , vertical presses are almost only used in small businesses and in the domestic sector for fruit wine making. Horizontal presses are mainly used today because they allow faster juice drainage and shorter pressing times compared to vertical presses.
