Tandem Press Brake

Description

1.Double linkage machine by CNC system can be stand-alone or dual -operating

2.It's standard 2 shafts back gauge system, as to complex shape work pieces, 3 or 4 shafts back gauge system and corresponding dies are available for your option.

3.Press brake using fully closed-loop electro-hydraulic servo control technology, slider position signals can be feedback to CNC system by bilateral gratings, then CNC system adjusts the amount of fuel tank by changing the synchronous valve opening size, hereby controlling the slider Y1, Y2 running on the same frequency, maintaining the parallel state of the worktable.

4.According to state of sheet metal on the press brake, CNC system can automatically control the table deflection compensation yielding uniform length of all workpieces angles.

FEA & Stress Analysis FEA & Stress Analysis

Stress Analysis & Finite Element Analysis.

The CAE software SOLIDWORKS is used as the method to analyze the linear static construction, stress, and deformation for press break and laser cutting machine frames. So for complicated structures, highly complex loading, transient modeling, and a combination of the above, FEA makes sense.

Main features

Request A Quote

Advanced proportional valve controls the hydraulic cylinders to work synchronously and achieve precise repeatability performance

Be capable of be controlled at random point within the stroke

Repeatability precision +/-0.01mm,parallelism precision +/-0.02mm

Deflection compensation table or crowning system for high precision

Control system together with linear scale, Bosch-Rexroth valves, servo motors and other famous brand elements to ensure excellent performance

Machine Block

  • CNC press brake features a rigid frame for minimum deflection under the load. Machine welding is made by welding apparatus & welding robots. After the welding,we make stress relief process by vibration system. After the stress relief process machine frame goes to CNC 5 axes machining centers for accuracy. All reference surfaces and connection holes are machined. By all this processes machine frame sensitivity is protected for a long life time.

Application

CNC Synchro Tandem Press brakes use 2 same models press brake united for bending longer sheet, especially over 8m length, 2 machines can be bending independent for high productivity short metal bending, it uses same controller with synchro technology; different models can be also united with tandem options, one big press bending thick&larger parts, one small press bending thin&small profiles, it can be work together bending longer parts with reasonable design on 2 different size machines.

 

Tandem press brake adopts the double or multi machine synchronous working principle.

The tandem press brake can process the extra long workpiece, such as the road lamp pole and power pole of the urban construction and expressway.
