III.Main Technical Parameters:

IV.Functions of CNC Axes:（Total 10 Axes:Y1 ，Y2 ，X， V， R， L1 ， L2 ， L3 ， L4， L5)

1.Ram Synchronization Control — Y1/Y2 Axes

Y1 and Y2 are the independent movement parameters of the two hydraulic cylinders controlled by the CNC system.Two linear scales (Y1 and Y2)are installed at both ends of the machine. They are used to determine the exact distance between the ram and the worktable. The linear scales are connected to the worktable, eliminating the influence of housing deformation on the ram position.During ram movement, position data is immediately fed back to the CNC system, which then calculates and outputs servo valve control signals (S1–S2) to control the output flow of the two electro-hydraulic servo valves, ensuring the synchronization of the two cylinders.

2.X Axis

The back gauge positioning travel control axis. Driven by an imported servo motor through a synchronous timing belt pulley and ball screw. The back gauge fingers remain synchronized, providing stable transmission, high precision, and low noise. The fingers are divided into four levels, enabling bending of wider sheets and providing material support.

3.R Axis:

Back gauge lifting control axis.Controlled by an imported servo motor,it can automatically adjust the height of the back stopper according to the workpiece requirements,improving work efficiency and enabling the completion of special workpiece.

4.L1 Axis:

It is the left punch section axis.

5.L2 Axis

It is the right punch selection axis.

6.L3 Axis

Center punch quantity selection axis.

7.L4 Axis

Center punch flipping.

8.L5 Axis

Front sheet support positioning.

V.CNC Axis Accuracy (The following accuracy is the factory acceptance requirement, with dial indicator as the inspection tool)

VI.Mechanical Crowning Automatic Compensation System

The mechanical crowning automatic compensation system effectively compensates for the deflection of the worktable during operation.The compensation principle is as follows:

VII.Product Structural Design:

1.Fully welded steel plate structure with high rigidity.

2.Structural components are derusted by sand blasting and coated with anti-rust paint.

3.The machine housings, upper ram, and lower worktable are machined in a single setup on a floor-type boring and milling machine, ensuring the parallelism and perpendicularity of all mounting surfaces.

Floor-Type Boring and Milling Machine

4.Upward-moving bending design ensures stable operation, convenient use, and safety.

5.Features a pressure holding dwell function at the bottom dead center to ensure workpiece accuracy.

6.Under relevant national standard conditions, bending angle accuracy can reach ±30′.  

7.The machine ram undergoes overall annealing in a furnace to eliminate internal stress,enduring good long-term accuracy retention.

VIII.Machine Ram Structure:

1.Upward-moving bending design ensures stable operation, convenient use, and safety.

2.Features a pressure holding dwell function ensures workpiece accuracy.

3.Large ram stroke; parallelism tolerance between the two sides is 0.02mm.

4.The measurement system connects two independent linear scales to a C-shaped auxiliary bracket which is integrated as one piece with the lower bed of the machine. This eliminates the influence of frame deformation on the absolute measurement of the stroke distance between the upper and lower tools.

5.Guiding of the upper ram: Our company’s upper ram is taller than that of typical manufacturers, and runs on the outer guide rail of the frame throughout its full stroke.  

IX.Hydraulic System:

1.Employs imported synchronous servo valve groups specially designed for press brakes, featuring fast response efficiency and extremely high synchronous control precision

2.The hydraulic system is built as a single manifold block, avoiding excessive pipeline connections and improving rigidity of the hydraulic system. Equipped with overload relief safety protection and a clear, intuitive oil level height display. The machine can operate continuously under rated load. The hydraulic system has no leakage, is continuously stable, and has high precision.  

3.Built-in large-diameter pre-fill valves ensure fast speed and low power loss.

4.Utilizes imported internal gear high-pressure hydraulic pumps,featuring high-pressure resistance, low pulsation, and low noise.

5.Cylinder seals employ imported sealing elements with a multi-guide structure. This ensures even force distribution, many years of trouble-free operation, low wear, and no leakage. The cylinder body inner surface undergoes fine honing, while the piston rod outer surface is processed with hard chrome plating, precision grinding, and micro-polishing, achieving a precision of 0.2 microns. This significantly extends the service life of the seals and cylinders.

6.The machine can operate continuously under rated load.The hydraulic system has no leakage, is continuously stable, and has high precision.

X.Electrical Control System:

1.Key electrical components adopt international renowned brands, complying with international standards for safety, long service life, and strong anti-interference capability.

2.The electrical cabinet is equipped with a ventilation and heat dissipation device to regulate the temperature inside the cabinet, ensuring the normal operation of all electronic components.
