Press brake bending is one of the important procedures in the sheet metal processing industry. It involves forming sheet metal into the desired profile by applying force to the workpiece. This process is generally performed using a press brake - a mechanical processing tool that is mainly used for sheet metal bending and forming. Bending is a common process used for manufacturing parts and workpieces in various industrious fields. It can deal with small parts as well as large workpieces. Due to the different thickness, hardness of the sheet metals, and different shapes of anticipated profiles. Therefore, we need press brakes with different tonnage and pressure to bend sheet metals.
It's a technique intrinsic to metal fabrication and holds paramount importance, transforming simple sheets into intricate and functional designs. Let’s navigate through the detailed intricacies of press brake, enjoy the shock of this bending technology.
二 、What is Press brake？
A press brake is a machine tool used in the metal working industry to bend and fold sheet metal. It is a key device in the manufacturing industry because it can accurately and precisely bend metal sheets to make various components and products. It usually performs the function of a brake press, which is a metalworking machine tool used to shape metal plates by bending them. Press brakes are widely used in various industries such as automotive, aerospace, construction and electronics to bend and form metal parts.
三、Types of Press brake
There are several types of press brakes on the market, each designed for a specific application based on factors such as material thickness, desired bending accuracy, and yield. A common type of press brake is a mechanical press brake, which uses a mechanical plunger to apply force to bend the sheet metal. Mechanical press brakes are popular for their simplicity and cost effectiveness, making them suitable for small and medium batch production.
Another type of press is a hydraulic press, which uses a hydraulic cylinder to apply force to bend metal. Hydraulic press brakes are known for their high accuracy and versatility, making them ideal for complex and high-volume bending tasks. They can also be equipped with advanced control systems for automated operation and precise bending angles.
The third type of press brake is the CNC press brake, which combines the precision of the hydraulic system with the flexibility of computer numerical control (CNC) technology. CNC press brakes offer a high degree of accuracy and efficiency, allowing operators to easily program complex bending sequences and angles. They are commonly used in industries that require high precision and productivity, such as aerospace and electronics.
Overall, the choice of the type of press brake depends on the specific requirements of the application, including material type, thickness, production volume and bending accuracy. Understanding the different types of press brakes and their functions is crucial to choosing the most suitable machine for a specific manufacturing task. With advances in technology and automation, press brakes continue to evolve to meet the industry's growing demand for efficiency, accuracy and versatility in metal forming processes.
四、Techniques and Methods in Press Brake Bending
（一）、The basic principle of press brake
The bending process in a press brake involves applying mechanical forces to the workpiece to deform it along a predetermined axis. This deformation causes a change in the shape of the workpiece, which creates a bend or Angle in the material. The basic principle governing this process is the concept of plastic deformation, in which a material is forced to yield and change its shape without breaking. The press brake uses hydraulic or mechanical forces to apply pressure to the workpiece to bend it along the surface of the die or tool.
（二）、Classification of bending methods
A press brake is a powerful machine that uses a variety of methods to bend sheet metal into the desired Angle and shape. Understanding the different bending methods of the press brake is fundamental to the success of metal manufacturing.
A common method of bending metal on a press brake is the air bending technique. In this method, the metal plate is placed between the upper and lower die of the press brake, and then the upper die is lowered to bend the metal. The metal bends to the specified Angle, but does not make contact with the lower die, resulting in a small radius of bending. This method allows for greater flexibility by bending metals of different thicknesses without changing the tool.
Another bending method used in press brakes is bottom bending. In this method, the metal plate is placed on the V-shaped mold, and the punch of the press brake comes down to bend the metal around the mold. Bottom bending is often used for thicker and heavier materials because it allows for greater control and precision during bending. This method is ideal for creating sharp bends and small angles in sheet metal.
The third bending method commonly used in press brakes is imprinting. Embossing is a precise and controlled bending technique that involves applying high pressure to the metal plates between the molds of the press. This method is commonly used to create deep bends and precise angles in sheet metal. Stamping produces sharp and clean bends, making it ideal for complex and detailed metal fabrication projects.
In addition to these methods, there are other specialized bending techniques that can be used in press brakes, such as rotary bending and wiping. Rotary bending involves bending metal plates around a rotating die, while wiping involves moving metal plates over a fixed die to create complex bends and shapes. These advanced bending methods require skill and expertise to perform effectively, but they offer greater versatility and flexibility in metal fabrication projects.
In summary, mastering the various bending methods used by the press brake is essential to obtain high quality results in metal manufacturing. Whether using air bending technology to achieve versatility, or using primer technology to achieve precision, understanding the principles behind each method is crucial to producing accurate and consistent bending. With proper training and experience, operators can effectively use these techniques to easily create complex metal structures and components.
五、 Precautions for the use of press brake
Press brakes are powerful tools for bending sheet metal and other materials in a variety of industries. These machines are very useful for creating precise bends in metal parts for a variety of applications. However, it is important to take care when operating these machines to ensure safety and efficiency.
First of all, before using the press brake, you must read and understand the user manual provided by the manufacturer. The manual will provide important information about machine functions, limitations and safety precautions. Be sure to follow all the guidelines outlined in the manual to prevent accidents and damage to the machine.
Secondly, it is essential to wear appropriate personal protective equipment (PPE) when operating the bender. This includes safety glasses, gloves and ear protection to prevent injuries from flying metal chips, sharp edges and loud noises. In addition, loose clothing and jewelry should be removed so as not to get stuck in the moving parts of the machine.
In addition, it is also important to check the machine before each use to ensure that it is in proper working order. Check for any loose or damaged parts and make sure all safety guards are in place. Never operate a press brake that is not working properly, as this can lead to accidents and injuries.
Finally, always pay attention to the bending capacity of the material being bent and the machine. If the material of the machine is too thick or too hard, it may damage the machine and cause poor bending quality. Make sure to adjust the machine Settings accordingly and always use the appropriate tools for the material being bent.
