Mechanical Punch Press STPP Series

The machine body is manufactured by welding the steel plates with good rigidity. The double crankshafts are designed in the reverse way, which makes the motion of the machine balanced and counteracts the side force of the linkage side block.

The slider is guided by eight-sided full guide rails, which has a stronger anti-unbalance bearing capacity, small lateral force, high precision and good retention.

What is Mechanical Punch Press?

A mechanical punch press is one type of punch press that is designed for cutting the desired shapes through the die sets. The primary mission of mechanical punch presses is to cut out certain shapes on sheet metal with the die just like general punch press machines and is critical for producing cuts with high precision.

Features

The hydraulic overload protective device is installed inside the slide block, so it works rapidly, sensitively, and reliably.
The clutch adopts a high-torque wet clutch, which has large torque, long service life and is not affected by wear and tear. At the same time, it has no pollution, low noise, and is sensitive to start and brake.
This mechanical punch press machine adopts the PLC control method, and it can be provided with the automatic production line and uncoiling leveling device to achieve automated stamping production of a single machine or many machines.
