There are a lot of forming processes that are normally utilised by manufacturers of various materials. One of these processes is punching. Punching is a type of forming process that forces a tool through the workpiece to effectively create and cut a hole. Some materials that usually undergo the punching process are sheet metal, vulcanised fibre, paper, and plastic sheet.
Many manufacturers choose the punching process over other types of forming processes as the process can create products in medium to high production volumes. The punching process is possible thanks to the wonders behind the punch press machine.
Quick Background of Punch Press Machine
A punch press machine is used in conducting the punching process. And given the very nature of the said process, this machine is truly designed to alter the size or shape of material through applying pressure to a tool, called a die, into the workpiece that is being held against it. The size or shape that will be produced on the workpiece is determined by the size or shape of the die.
The very function of the punch press machine becomes possible thanks to the presence of the die and the punch. As mentioned, the die determines the size of the shape of the workpiece. Hence, it is usually clamped onto a bed or anvil, making it perpendicular to the path of the ram. The punch, on the other hand, is attached to the accompanying hydraulic-powered ram of the punch press machine.
Punch press machines are maximised by a lot of manufacturers as they offer high rigidity, high precision, and reliable operations. With proper use, they are likewise deemed to be safe and efficient.
Working Principles of Punch Press Machine
The punch press machine relies heavily on two vital components: the punch and the die. During the operation of the machine, the punch is pushed against the workpiece that is being held in the die. Consequently, a blanking die cuts out and produces a flat piece of material, converting it into a blank that can fit dies for succeeding punch press machine operations.
To date, there are two common types of punch press machines that manufacturers can use. One of these types is the computer numerical controlled (CNC) punch press machine. CNC punch press machines generally do the same work that has been previously discussed. They, however, rely heavily on a computer in conducting the punching process. The presence of specific software allows the machines to streamline the production operations and automate every step possible.
Mechanical punch press machines, alternatively, are another type of punch press machines that can be further categorised into full revolution and part revolution. Full revolution punch press machines require a full cycle of the crankshaft, while the part revolution ones only need a partial cycle of the same crankshaft.
