Advantages of Electro-Hydraulic Servo Double Machine Linkage Tandem CNC Press Brake Bending Machine

Reading Time: 3 minutes

As the key production equipment of metal sheet metal, the structure of the tandem CNC press brake bending machine and the function of the numerical control system largely determine the final performance of the tandem CNC press brake bending machine.

Synchronous torsion shaft structure: torsion shaft tandem CNC press brake bending machine includes hydraulic tandem CNC press brake bending machine, torsion shaft tandem CNC press brake bending machine with three cylinders, four cylinders and eight cylinders, and double machine linkage torsion shaft tandem CNC press brake bending machine.

Servo CNC synchronization: electro-hydraulic servo CNC tandem CNC press brake bending machine, four axis and six axis electro-hydraulic servo tandem CNC press brake bending machine.

Other structures: manual tandem CNC press brake bending machine, downward moving tandem CNC press brake bending machine.

Performance and characteristics of electro-hydraulic servo double machine linkage tandem CNC press brake bending machine:

Working principle of dual machine or multi machine synchronization: the electronic hydraulic proportional valve of Bose Corporation is used for servo synchronization, and this proportional valve has very good performance.

Small friction in mechanical actions, exquisite electronic amplifiers, and electric magnets provide efficient control and sustained response.

There are two raster displays on both sides of the machine, which continuously check the position of the slider and feed back information to the control system. The control system then controls the electro-hydraulic valve to drive both cylinders to move simultaneously.

Due to the fact that the raster display is installed on the “C” board rather than directly on the column, the deflection of the slider and body during operation will not affect the measurement and control accuracy.

When the two machines work at the same time, the Potentiometer installed in the two machines converts the mechanical synchronization signal into the same electronic signal and feeds it back to the synchronization board and the control system.

After the signal is amplified by the doctoral amplifier, the dual machine linkage is controlled by an electro-hydraulic synchronous valve, thus achieving high accuracy.

Through computers, communication with machines is possible. Computers have multiple languages and can automatically calculate and adjust bending force. Simultaneously able to calculate control stop and gear change point. The number of strokes (Y1, Y2) of the slider can be changed according to the user’s needs. Excellent guidance system, position measurement system, and hydraulic balance system to meet different lengths and special needs. The workbench compensation device is used to prevent the influence of machine deflection and ensure the accuracy of the workpiece.
