Quantity:
  • NC Series
  • Durmapress
Product Description

General Features

  • NC Pipe bending machine adopts boom lifting clamp structure

  • Hydraulic bending mode

  • Hydraulic guide side pushin mechanism

  • Hydraulic system is equipped with water cooling device , which is convenient for users to control the oil temperature

  • Pipe bending direction is clockwise from top view

  • Electrical control and operation interface

  • The operation interface of NC hydraulic pipe bending machine adopts single chip microcomputer

  • Digital display resolution : turn 0.15°

  • NC hydraulic pipe bending machine adopts single chip microcomputer controller

  • Bending parameters can be set ( preset ) on the operation interface .

  • NC Hydraulic pipe bending machine with the following characteristics .

  • Maximum memory capacity can up to 16 bends per group

  • Directly input bending machining paramenets , the machine can be executed step by step and suspended during automatic operation , so that the specal pipe can be manually interfered when bending , and the automatic operation can be resumed with automatic and manual pause , emergency stop function .

  • Working program and bending program memry storage time is unlimited . and will not be lost due to power outage or long-term use .

  • Program edit with minor correction input , the original processing data will not be lost due to multi-times program modification .

  • With processing quantity and processing time counting function

  • Real time display the position and bending angle of each action axison screen

  • In case of any accident or error during auomatic processing , the machine can be suspended , and the machine can continue to finish the unfinished work , so as to advoid the waste .

  • Automatic or manual mode setting can be set according to the difference of processing feature, such as whether there is a piercing heart , auxiliary push and so on .

  • With multiple delay parameter settings , the most appropriate time difference can be set for each acttion axis to meet the requirements of various bending changes .

  • The machine is with automatic detection function of each buttom and circuit output / input board , which can easily find the possible fault location .

  • Closed loop control
