Body
The base is welded with steel plates and processed as a whole to ensure the rigidity and machining precision of the body.
The working table adopts a three-plate structure and a hydraulic convex automatic compensation system, which solves the deformation of the working table and ram during the sheet metal bending process and its impact on the quality of the bent part.
The compensation value is automatically adjusted by the CNC system, which is convenient and accurate, and can effectively improve the accuracy of sheet metal bending.
To knock
The ram main plate is welded from a whole steel plate and guide rail, and is connected to the cylinder rod by bolts. The oil cylinder is fixed to the oil cylinder connecting plate above the left and right side plates of the bed. Through hydraulic servo-synchronous control system, the piston rod drives the ram to move up and down. The accuracy of synchronous control is high, which can effectively improve the accuracy of repeated positioning of the ram and the accuracy of sheet metal bending.
Hydraulic system
The hydraulic system of the CNC press brake adopts an integrated hydraulic control system, which effectively reduces the installation of pipelines, overcomes the phenomenon of oil leakage, is convenient for maintenance, improves the working stability of the machine, and makes the appearance of the machine more beautiful and concise.
Back gauge
The CNC press brake is equipped with a large, high-speed thrust mechanism that is driven by a linear guide rail and a ball screw.
The system can control up to six axes based on user needs, including X1 and positioning of the part.
Mold
According to the user's needs, sectional upper dies with varying lengths can be equipped. They can be assembled to a specific length to meet special part processing requirements.
The equipment can also be equipped with a hydraulic upper die clamping device or a mechanical quick clamping device to reduce the labor intensity of workers and improve production efficiency.
CNC system
The CNC system uses advanced press brake control systems from well-known brands such as Delem, Esa, Cybtouch and Estun, making it one of the most advanced systems in the world.
Protective fence
Protective barriers are installed on the left, right and rear sides of the press brake to prevent machine operators or outsiders from accessing the hazardous area when the machine is in operation. According to user requirements, an upper limit switch can be installed on the inner side of these guardrails.
If the safety fence is opened while the machine is in operation, the safety protection alarm indicator will light and the machine will stop working. After the operator resets the guardrail and presses the reset button, the machine can resume operations.
Front support structure
The front support frame is mounted on the front plate of the machine, making it convenient to hold large-sized workpieces for bending and forming.
The distance between the two supporting structures can be adjusted as per requirements, and the height can also be modified based on the height of various bottom molds to accommodate the bending requirements of different sized plates.
