Manzoni 300-ton press , model A2MF , is a double-column mechanical machine used primarily in the metalworking industry. This press, designed to withstand a nominal force of 300 tons , has two connecting rods to ensure even force distribution during the machining process. Let's take a closer look at its features.
The worktable of the Manzoni 300-ton measures 1445 x 1114 mm , providing a large and robust surface for processing sheet metal and other metal materials. The ram (or slide) measures 1147 x 1100 mm , ensuring precision in the pressure applied. The slide stroke is 200 mm , while the clearance at top dead center (TDC) is 710 mm . The machine is capable of operating with fixed strokes, with a speed of 30 strokes per minute , making it ideal for medium-sized production runs.
Manzoni 300-ton press appears to be an imposing and stable structure, equipped with a double column for greater strength. The main components include the slide, the worktable, the connecting rod system, and the motor, which provides the mechanical movement. Although used, this press is described as working , which guarantees that all its parts are still in good condition.
To use the Manzoni A2MF , the operator loads the workpiece onto the worktable and adjusts the slide as needed. During operation, the ram moves downward thanks to the connecting rod system, applying uniform pressure to the material being worked. The fixed strokes and speed of 30 strokes per minute allow for a constant and predictable work rate, particularly suitable for mass production.
Accessories that can be combined with the Manzoni 300 ton include automation systems and safety devices, such as photocells or locking devices. Regular maintenance includes lubricating the connecting rods and sliding system, as well as periodically checking the motor and slide to prevent excessive wear.
To calculate optimal usage parameters, you need to consider the force required to deform the material and the speed of the impacts. The force can be calculated using the formula:
F=σ×AF = \sigma \times A
where F is the force, σ is the yield stress of the material, and A is the cross-sectional area of the workpiece. The optimal number of strokes per minute depends on the material type and thickness.
The Manzoni 300-ton A2MF is widely used in industries such as cold forming and sheet metal component manufacturing. Buying a used machine like this offers significant financial advantages, as mechanical presses are built to last and, if properly maintained, can provide years of productive use even after the initial owner.
In the absence of CE , it is possible to adapt the machinery to current standards by installing modern safety devices and compliant electronic control systems.
The Manzoni 300-ton is an excellent choice for those looking for a robust and functional machine, especially in the used market, where high-performance machines can be obtained at a significantly lower cost than new ones.
