WE67K Hydraulic Alloy Plate Press BrakeControl TechnologyThe synchronization of press brake adopt the technology of full loop electro hydraulic servo control. the positioning signal of the upper beam are feed back by raster (light-ruler) to CNC system and CNC system will check the opening size of synchronization valves. adjusting the inlet oil amount. to realize the synchronizing movements of the upper beam (Y1. Y2). and keep the worktable are always parallel situation. Following the situation of sheet metal to be bended. CNC system control automatically the amount of the crowning compensation of worktable to realize that angle being bended of work piece can keep same along the full work piece length.Crowning CompensationCrowning compensation system on worktable can make a work piece having a same precision full along the length of the work piece. A crowning compensation system is composed of a group cylinders in line in worktable. which can from a relative movements of worktable. forming a curve needed of adding conversion to worktable. to ensure unchanged the relative position to the upper beam of worktable after the worktable being under pressure. The crowning compensation amount is automatically calculated out by CNC system according to the worktable's situation.Typical aspect of sheet metal after bended hydraulic compensation system           Mechanical compensation system       No compensation systemBack Gauge                     (Stop-finger structure)                                                    (Stop-finger photo)Upper tool clamping         (Upper tool mechanical fast clamping)                      (Lower tool multi -V clamping)          All tools are full grinded and with hardening.
