The Press Brake and Other Machines Used in Metal Bending
There are a lot of machines that can be used in the fabrication of sheet metal parts. One such machine is the brake press .It is a machine used to bend sheet metal .There are a lot of machines that can be used in the fabrication of sheet metal parts. One such machine is the brake press .It is a machine used to bend sheet metal .There are other machines which are used to punch holes to be used with screws or nuts and bolts. The most common machine that is used for this is the punch and shear cutting tool. Another common type of cutting machine is the CNC Plasma Cutting Machines. All these cutting tools can be used in the industries for cabinet making, production of furniture, metal working and wood working among others.
These machines are quite reliable as they provide safe and effective ways of cutting metal sheets. The brake press bends metal sheets by applying a significant amount of force using mechanical or hydraulic processes or both. The metal sheet is placed between a punch and die that are close together. In order to come up with quality defect free bends when using the brake press proper methods should be applied in the process.
The punch and shear cutting tools basically use shearing and punching in order to cut metal. Punching which involves drilling holes in metallic materials is usually carried out by a punch block and a pin. The punch block is replaceable and the pin is specially formulated and hardened enough to perform the task. Shearing in simple terms involves a quick and safe way of cutting hot flat strip metal, solid square bar and round metal rods to length using the punch and shear.
The CNC Plasma Cutting Machines uses the plasma cutting process to cut steel and other metals of varying thickness. The machines use inert gas blown at high speed out of a nozzle to the surface being cut turning that gas into plasma. Plasma is usually hot enough to melt the metal being cut and moves very fast blowing the molten metal away from the cut.
Punching machines are also used in bending metal. They use the punching process which is basically a tool called a punch. The punch is forced through the metal using a punch press to come up with a hole via shearing. This is the cheapest method of creating holes in metal surfaces. Band saws can also be used to cut metal using a blade. The blade has teeth on one edge and can cut irregular, curved or straight metal shapes.
There are some safety measures that should be considered when using these cutting tools. Every industry introduces its workers to a lot of power hazards before they start using the cutting tools. For instance using the CNC Plasma Cutting Machines, proper eye protection like welding goggles should be used to prevent eye damage from debris commonly known as arc eye. Machines like band saws and the brake press should only be used by qualified workers to avoid any form of accidents. Protective gear should be won all the time at the industry to prevent head injuries incase an accident occurs. Remember prevention is always better than cure.
