135 Ton Press Brake DA52S Hydraulic Bending Machine

135 Ton Press Brake is a kind of forging machinery, the main function is the metal processing industry.

Products widely use in: aviation, shipbuilding, metallurgy, instrumentation, electrical appliances, stainless steel products, steel structure construction and decoration industries.

WE67K-135T/4000 hydraulic bending machine is currently the first choice for sheet metal processing of sheet materials, especially large sheets. A variety of different molds can use for bending, stretching, rounding, punching, etc.

135 Ton Press Brake Main features

The whole welded machine structure achieves high rigidity; the machine design by ANSYS software which can ensure the reliability and precision of the CNC press brake.

WE67K-135T/4000 hydraulic bending machine redesigned based on users’ preference to increase productivity and keep the costs at minimum level with high bending accuracy and low-cost maintenance.

High quality and repetitive bending accuracy is obtained by using synchronized cylinder and proportional valves

Bending angle calculation and back gauge position calculation can be achieve by inputting metal sheet material information, sheet size and punch and die size.

Crowning system can work with CNC controller automatically to achieve higher bending accuracy and linearity. Hydraulic crowning and motorized crowing system are optional.

CNC back gauge with several axes can work with different shape work-pieces well.

Features of 135 Ton Press Brake

1. The frame has good rigidity, high processing precision, good manufacturability, and convenient installation and transportation.

2. The electro-hydraulic servo CNC bending adopts the integral slide block and the worktable, the force is more reasonable, and the load is evenly distributed.

3. The electro-hydraulic servo numerical control bending slider is rigidly connected with the oil cylinder, which better guarantees the synchronization accuracy requirements of the slider in the fast forward, work forward and fast return states. 135 Ton Press Brake

4. Due to the feedback of the grating ruler and the control of the synchronous valve, the machine has strong anti-eccentric load capability.

5 The advanced variable oil pump technology is adopted, which can save a lot of energy consumption (about 50%) and reduce the processing cost.

6. The operation and maintenance are more convenient and the reliability is higher;

7. The operating cost is the single unit price of the dual unit linkage. The efficiency and processing accuracy are higher than that of dual machines.

Automatic Crowning System

CNC crowning ensures a constant bend angle across the full length of the machine. This is achieved by pre-loading the machine, to offset any possible deflection under load or compensate for any tool wear, so that under load contacting surfaces are parallel to each other.

With CNC crowning systems the press brake control pre-program with machine characteristics and deflection data. With manual crowning a simple spread sheet or chart can be easily developed for each application.

How to choose an electro-hydraulic bending machine

1. The main difference between electro-hydraulic servo CNC bending machine and an ordinary CNC bending machine lies in whether it has feedback closed-loop and whether it has electro-hydraulic bending machine compensation.

2. Calculate how many tonnages need to purchase according to the material and thickness of the sheet metal to process and bent. Note: The tonnage here refers to the maximum pressure of the bending machine, not the weight of the electro-hydraulic servo CNC bending machine;

3. Determine the width of the knife-edge, the depth of the throat and the distance between the columns of the electro-hydraulic servo bending machine according to the length of the stainless steel and other plates to process

4 There are many additional functions that can select for the electro-hydraulic servo synchronous bending machine. This needs to be customized according to the requirements of the workpiece, such as the number of axes, compensation type, laser test, safety protection (laser protection or light curtain protection), etc.
