The press brake is a device that is able to bend sheet metal. The material is placed over a V-shaped die and it is then pressed down from above with a punch. These machines can bend parts that are simple or complex and are utilized in a variety of industries ranging from automotive and aircraft to housing and cabinets. When there is a requirement to bend metal panels, a press brake is vital, making these machines a staple in machine and job shops. What size of press brake should I purchase?The most crucial factors to consider when purchasing a press brake is the tonnage and bending length. These specifications are established based on the dimensions and thickness of the material you intend to bend. Making a plan and understanding your application will allow you to make the best choices. Tonnage The press brake's bending force, known as tonnage, determines the much pressure is applied by the punch during a bend. A higher tonnage permits bending heavier and more durable metals while lower tonnage is more appropriate for thinner metals. Bending length The length of bending for a press brake is the longest length that a sheet that can be bent. If you have a very small press brake with 4' bending length, you will not be able to bend a 6' piece of sheet metal because it's way too long. A press brake must have a bending distance that is slightly longer than the sheets that you're bent. What is the reason length and tonnage important? These factors are important as every brake has a special load limit, which is determined in tons per inch in the middle of the press. Incorrect tonnages can result in damage to the ram of the press or die part and, in extreme cases, even destroy the equipment. You can use basic math to determine the limit of your press brake's maximum load. Let's imagine this scenario: Measure the distance between the columns and multiply it by.6. Then , divide the result by the number of tons. If there is 10.6' of columns between them on a press brake that weighs 350 tons, multiply that number (10.6 x 12"'" equals 127.2"') by.6 (which is equal to 76.32) to get the amount of tonnage. 350 / 76.32 = 4.58, so that press brake's limit of load would be 4.58 tons per inch. Then if you chose to bend a 5' sheet using that press, you'll need to select a power of 275, because (5 x 12' 60') + 4.58 equals 275 tons. The scenario could be different for different types of metals and for different types of machines. There are a variety of calculations that can be utilized to determine the press's power. These calculations are available in the operator manual or on the chart of the machine. However , a person operating a press brake should be aware of the type of bend he or she is bending and calculate the proper press power needed in order to avoid using too little or too much, which can damage the machine. Which one should I get? One of the most well-known kinds of hydraulic press brakes are when combined with a CNC control, it is known to reduce job setup time and greatly enhance efficiency. A CNC press brake for sale can be found in a wide variety of sizes and tons.
