Main Features

  • Welded steel plates and gantry-type cabinet are adopted for the machine body, which is marked with high rigidity and extremely small deformation. In the case of high-speed stamping and feeding, the machine body remains steady and keeps vibration minimal, ensuring the long-term precision of the machine tool.
  • The main transmission mechanism has frequency conversion for speed variation, and ensures steady movement.
  • High-precision and large-capacity rolling bearing is adopted for the main shaft, ensuring the transmission precision and reducing the total clearance and heat impact.
  • Octahedral needle guide rail is adopted for the slide block, and is marked with reliable and high precision in guiding and convenient adjustment, thus greatly enhancing the precision of the slide block.
  • Electrical adjustment is adopted for the die-set height of the slide block, convenient for operation and with digital display for the die set height and in the precision up to 0.1mm.
  • Hydraulic overload protection device is adopted, and is highly sensitive and reliable in operation. It enables automatic return to the original position after overload, reduces the machine stop time, thus enhancing the efficiency.
  • Forced thin oil lubrication system is adopted for the machine in complete set to ensure complete lubrication for the machine as a whole.
  • Electronic cam controller is adopted. The system consists of a rotative transformer and a controller. It achieves real-time monitoring and dynamic tracing of the crankshaft position and automatic calculation by means of the rotative transformer so that the slide block can stop at the top stop.
  • Imported safety duplex valve is adopted, and is marked with quick response in high accuracy, ensuring the reliable control of the clutch.
