Punch Press

The punch press is a large machine with a hydraulic ram on the top. It usually has a workstation in the front where a worker can operate the plunger. When the worker engages the ram, the workpiece is pressed against the fixed mold. This will create a hole in the workpiece and a new workpiece in the workpiece that has the same shape as the mold. The punch press is especially suitable for the mass production of small objects with uniform shapes from raw materials. Even though workers can manually punch holes in the workpiece, a faster and more effective solution is to use a punch.

How does a Punch Press work?

Infinite stroke control in many punch presses today allows the operator to adjust the indenter stroke to 0.0005 inches. Increase and improve forming accuracy. Due to changes in material thickness, stroke control accuracy can also help make small adjustments required. Most modern presses can also control the upstroke of the hammer. This function allows the programmer or operator to set the upstroke of the forming tool high enough to remove any forms generated, and at the same time, it can also raise the tool to a height below the top dead center to maximize speed And efficiency.

Upforming, which simply means a forming procedure with a bottom slide, a formation cylinder, or a moving wedge mechanism, also helps the die cutter to create high shapes. Many punch press forming tools are designed to be formed up using spring-loaded pullers in die assemblies resulting in high die heights. Even so, tall dies take up space in the turret or punching head and thus reduce the space available for some molds. In most up-moldable machines, the die is located lower in the pocket or die holder, providing additional space between the upper and lower tools to create tall forms such as tabs, louvers, large embossing, and hinges.


Advantages of a Punch Press

High Precision 

The punch press not only helps to maintain high production standards but also has long-term stability to ensure precision throughout its service life. There are no human errors or inconsistencies that slow down production.


Labor-saving and safe

The punch press is very safe and automated. Even if operators may be needed, with computer-aided detection, these machines can detect feed errors or breakages to reduce waste. Machines may be equipped with other safeguards to prevent injury to workers. As the machines are automated, productivity can increase.


Maximized Yield

Computers can nest dies and punches to maximize material efficiency. It reduces waste. Newer punch presses are also able to lower your energy bills, which also helps with your profits.


Mass Production

Today's punching presses are usually hydraulically powered, which increases the punching speed.  Mechanical punches are a different subtype description. Both will help improve the efficiency of the parts while being very safe.


Machine Longevity

Punch presses are designed to last for a long time but require proper care. It is important to maintain the tooling, punch, and die to protect the machine and make the most of your money. Over time, it may be necessary to sharpen the stamp and die. You will notice that the edges of the punched parts are not as sharp. Store the die and punch correctly to protect the edges.


CNC, Manual and Mechanical Punch Presses

Although some manufacturers use manually operated punch presses, many use a numerically controlled (CNC) press. The CNC-controlled punching machines use the same hydraulic cylinder to strike pre-formed holes in the workpieces. The distinction, though, is that the CNC-controlled punching presses are semi-automatic on a machine. As with other CNC-controlled devices, CNC-controlled punch presses allow manufacturers to streamline manufacturing operations.

Instead of manually running a punch button, manufacturers can configure it to run automatically. CNC punching machines do need human intervention but are capable of automating certain activities that would otherwise need human interaction. In addition to hydraulic punching presses, mechanical punching presses are also available.
