A press brake is a type of machine used for bending sheet metal plate. It forms predetermined bends by clamping the workpiece between a matching top tool and bottom die.
Typically, two C-frames form the sides of the press brake, connected to a table at the bottom and on a movable beam at the top. The bottom tool is mounted on the table, with the top tool mounted on the upper beam.
Press brakes often include multi-axis computer-controlled back gauges. They allow operators to position material correctly and sequence the bends step-by-step until completed. Optical sensors allow operators to make adjustments during the bending process. These sensors send real-time data about the bending angle in the bend cycle to machine controls that adjust process parameters.
Tech features
Controller
We choose a series of control systems of internationally renowned brands, which are specially created for high -end bending machines to meet the high standard requirements of customers.
These control systems adopt top CNC technology and intelligent algorithms to ensure that bending processing is accurate and correct, and its stability and reliability are excellent.
They have powerful functions, flexible operations, support multiple modes, and easily meet different processing needs. At the same time, the humanized interface design makes the operation more convenient.
Backgauge
After the CNC press brake, the material is based on its high -level intelligent design, providing unprecedented accuracy and efficiency guarantee for metal plate bending.
It adopts advanced CNC technology. Through accurate computing and automatic adjustment, the precise control of the post -material block position can be achieved to ensure that each bend can achieve extremely high accuracy and repetitiveness.
At the same time, the rear block also has an intelligent avoidance function, effectively preventing the processing of processing parts from colliding with it, and improving the safety and stability of the entire processing process.
Hydraulic Valve
The German Rexroth fully closed-loop electro-hydraulic servo high-frequency synchronous control system is adopted to ensure that the machine tool has high stability and high precision in the process of high-speed operation.
Advantage:
The frequency response (response frequency) is higher
The famous brand motor increases the service life of the machine and keeps the machine working in a low-noise environment.
Punches & Dies
Sheet Metal Press Brake punches and dies will be one of the most important topics we discuss before you place the order. Any bending shape will be completed by a suitable set of punch and die. We can provide appropriate toolings according to different bending requirements of customers.
