The press brake is a machine that bends sheet metal. The metal is placed on a V-shaped cutting die which is then pressed from the top using a punch. These machines are capable of bending simple and complicated parts and can be utilized in a variety of industries, including aerospace and automotive as in cabinets and housing. A press brake is essential for any task that requires the bending of panels made of metal. They are commonly used in job shops. What size of press brake should you buy?When buying a press brake, the primary elements to consider is its tonnage and length of bend. The specifications are determined by the size and thickness of the material that you bend. Understanding your project beforehand and planning it according to your needs will help you make the right choice. Tonnage Tonnage refers to the pressure that can be applied to a bend by the press brake. More tonnage is able to bend thicker and harder metals, and lower tonnage is suitable for lighter metals. Bending length The longest length of a sheet of steel that can be bent is called the bending length of a presse brake. A tiny press brake will not allow you to bend six feet of sheet metal if it is equipped with a 4' bending length. You want to get a press brake with an bending length that is just a bit longer than the length of sheets you will be bending. Why is the length and tonnage so important? These are essential factors because every press brake has a special load limit, which is determined by tonnage per inch, in the center of the press. The wrong tonnage could cause damages to the press ram the die or work part and, in extreme circumstances, may even damage the entire machine. The process of determining the limit of load on a press brake is a matter of fundamental math. Let's think of this scenario: Find the column's distance and multiply it by.6. Then divide this sum into tons. So if you had 10.6' in between columns of a 350 ton press brake, then you'd calculate the amount of inches (10.6 12'" = 127.2'') times .6 (which is 76.32) and divide it into tonnage. 350 / 76.32 = 4.58. This means that the brake's maximum load is 4.58 tons per inch. If you choose to bend a 5' piece on the press, you'll need to use a press power of 275, because (5 x 12'' = 60) x 4.58 = 275 tons. This scenario could change depending on the kind of machine or metal. There are a variety of calculations that can be utilized to determine the press's power. These calculations can be found in the operator's manual or on the machine's chart. However a press brake operator should be aware of the type of bend the machine is bent and determine the correct press power needed, to avoid using too little or too much, which can damage the machine. Which press brake should I purchase? Hydraulic is among the most sought-after kinds of press brakes. When coupled with a CNC controller it can reduce setup time and increase efficiency. It is possible to find a hydraulic press brake variety of different sizes and tons.
