Basic bending tool for brake press and the advantages of high-quality tools
Press brake is an important tool in the metalworking industry, it is a machine used to bend, fold or shape sheet metal. These machines are widely used in the construction, automotive, aerospace and other industries involved in sheet metal processing and manufacturing. The workpiece produced by press brake can come in a variety of shapes, from simple to complex parts, and beyond that, it comes in a variety of models and sizes, but standard parts include upper and lower molds, hydraulic cylinders or motors, and a range of auxiliary equipment.
In this article, we will discuss the basic bending tools of press brakes, different pressure systems, power units, and the advantages of high quality press brake tools.
Pressure system
The pressure system of the press brake is the force that drives the bending process and is equipped with a variety of pressure systems, including mechanical, hydraulic, electric and pneumatic, the two most common pressure systems are hydraulic and electric.
The hydraulic system is the traditional method, which consists of a motor, hydraulic pump and hydraulic cylinder, and the electric system is newer and more efficient, using servo motors and ball screws to generate the necessary force.
Electric power equipment
The power unit applies pressure to the slider, causing the upper die to move downward, pressing the metal plate into the lower die, thus completing the bending process and producing the desired workpiece through repeated and precise bending operations.
The power unit is the main source of energy that drives the bending process, and there are two types of power units, hydraulic and electric. The hydraulic system uses hydraulic oil pumped by the motor to drive the cylinder of the press brake; Electrical systems use electric motors to generate the force required for bending.
Press brake Dies
The die of the press brake includes a conventional die assembly, which is composed of two parts: the upper die (punch punch) and the lower die (V-shaped die), and the two molds with different shapes are combined to act on the plate to form various shapes of the workpiece. It is important to choose a different press brake die according to the type of metal sheet used.
For example, when working with metal plates with high tensile strength, the mold must also have a matching hardness to prevent mold damage or incorrect bending of the metal plate.
A traditional die set consists of an upper die and a lower die that work together to bend the sheet metal. Punches usually use materials with higher hardness to efficiently extrude or cut sheet metal. Again, the lower die requires a material of the same hardness because the punch presses the metal plate into it.
The upper die (punch) of the press brake can have a special shape and Angle to produce a workpiece with a specific shape. These special punches include standard punches, gooseneck punches, belt punches, arrow punches, acute punches, etc. Press brake dies are generally made of hardened steel, such as chromium molybdenum steel, to prevent the press brake from cracking due to excessive pressure or high plate hardness, and the use of high-hardness materials also helps to ensure the durability of the punch.
The lower die of the press brake can be divided into v die, u die, single die and double mode.
V-shaped and U-shaped molds are made of the same material as punches and are known for their durability and high hardness. The size of the opening of the V-mold affects the choice of the bending radius of the workpiece and the bending method. The grooves of the lower die are designed to fit with the upper die, allowing the sheet to be securely fixed and molded into the final shape of the workpiece.
Punches and dies are the main tools used in the punch brake. In addition to these, the press brake also has other necessary auxiliary tools such as rear gauge, clamping tool and support frame. The other components of the press brake work together to ensure accurate bending position, Angle and speed, thereby improving the accuracy and quality of the final workpiece.
Use high quality press brake tools and accessories
The use of high-quality press brake tools, punches, dies and accessories has a range of benefits that increase the accuracy of parts by providing precision press brake dies and other accessories, resulting in higher quality products while increasing safety levels and reducing maintenance costs.
Advanced, high-quality accessories increase bending speed, accuracy and final product quality. Die materials should be strong enough to withstand wear and damage, high-quality tooling materials can also extend the service life of the tool, prevent deformation, high-quality tooling to ensure the quality of the bending workpiece, reduce the error of the final product, while improving the production efficiency of the press brake, reduce production costs.
Molds with high matching levels and high quality are very effective in sheet bending. For example, accurate positioning of the rear gauge and each shaft can improve the accuracy of the workpiece length and dimension; High quality hydraulics provide consistent stroke and eliminate corners caused by inconsistent speeds.
In summary, the press brake is an essential tool in the metal manufacturing industry, and its bending tool, pressure system and power device are an important part of its operation, and have different and unique effects in the operation process. High quality press brake tools and accessories ensure high precision, durability and productivity, resulting in higher quality products, improved safety and reduced maintenance costs.
