Press Brake

The machine is in an overall welding and overall processing structure, and the main parts of machine are all analyzed by ANSyS finite element analysis software, which has ensured the reliability of machine and the precision of entire machine. The CNC control system adopts Netherand DELEM, ltalian ESA, or Swiss CYBELEC products, which can achieve the functions of graphic programming for bending angle, compensation for angle amendment, automatic calculation also adjustment of bending pressure, automatic calculation of compensation for workbench distortion, extending length of workpieces bending pressure for bottom bending,open distance, and automatic withdrawal of rear stopper, etc.

2024 Series Press Brake is a new CNC bending machine launched by Dama in 2024, and is suitable for manufacturers with high precision and cost performance requirements.  4-axis CNC Bending Machine is our most popular model by volume and a true workhorse, which is constructed of high quality parts and offers serious reliability. Y1 & Y2 Synchronization technology ensure high approach, bend and return speeds. It`s bending length capability and pressure range can be customized to meet various producing requirements.

The CNC press brake uses the mold (general or special mold) to bend a cold metal sheet into a workpiece of various geometric cross-section shapes. It is a sheet metal forming machine designed for cold rolling sheet metal processing. It is widely used in sheet metal bending, such as automobile, aircraft manufacturing, light industry, shipbuilding, container, elevator, railway vehicles and other industries.

The E21-controlled NC press brake provides a complete solution for the 2-axis traditional bending machine application.

The E21 control system with Hd LCD screen, with English and Chinese languages optional, one page display programming parameters

X, Y axis intelligent positioning, can also be manually adjusted according to the need to remove the mechanical hand positioning device

Built-in pressure holding time, unloading delay setting function, easier operation, no time relay, reduce cost

With one-click parameter backup and recovery function, parameters can be restored at any time as required, reducing maintenance costs. Support multi-step programming, complex workpieces can be processed at one time, improve production efficiency and processing accuracy.

1. Steel plate welded structure, hydraulic transmission, accumulator return, holistic processed, vibrating toeliminate stress,high strength and good rigidity.
2. Mechanical torque system makes sure the synchronization of cylinders. 
3. The stroke of slider and back gauge is adjusted automatically by double servo motors or transducer, and showed on CNC Mechanical torque or NC control panel. 
4. Slanting wedges can be chosen to install on the top dies which can be adjusted by hands or automatically. Hydraulic compensation system is installed under the worktable.

The fuselage adopts an integral steel plate welded structure and is tempered by large tempering furnace equipment to eliminate deformation caused by welding stress and processing stress and ensure the accuracy of the machine tool. 
Imported internationally renowned brand electro-hydraulic servo valves and scales form a precise control method The slider position feedback accuracy is high, the operation is accurate and smooth, the synchronization performance is good, the bending accuracy and the slider repeated positioning accuracy are high. 

The fuselage adopts integral welding and tntegral machining structure,and the main components of the fuselage are analyzed by ANSYS finite element analysis software to ensure the reliability of the machine tool and the accuracy of the whole machine.
The main cylinder on both sides breaks through the stroke control mode of the traditional mechanical block type bending machine,but adopts the closed-loop control mode composed of the electro-hydraulic servo valve imported from Germany and the imported grating ruler.The slide block position feedback accuracy is high,the operation is  accurate and stable ,the synchronization performance is good,the bending accuracy of the rear stop,and the rear stop mechanism of multiple rear stop shafts with more complete functions can be used according to customer needs.

1. The bending machine frame is integrally processed by a large floor boring and milling machine.
2. The forged material shaft body has good rigidity and elasticity, and has a fine adjustment device, which is weak against the partial load. 
3. The user can customize the mold segments 1015203050100300(cm). Use ESTUN or DELEM brand CNC system for users to choose.In the system, the plate thickness and length parameters are input and the system will automatically perform deflection compensation.
