Marine bending machine

steel sheet rolling machine

W11NC marine bending machine is mainly used for rolling ship shell circular plate and pressed corrugated bulkhead. According to customer requirements, can be designed into symmetric and asymmetric three roll bending machine, The upper roller of marine plate bending machine is arranged on the upper part of the rigid beam, between the upper roller and the lower roller and the lower crossbeam has a plurality of rollers, in order to improve the stiffness of the upper and lower rollers, three roller driven.e two lower rollers of the rolling bearing are respectively driven by the special design of the speed reducer to rotate, and the torque of the rolling plate is provided. In the lower part of the lower roller is provided with a plurality of groups of supporting rollers, which can improve the rigidity of the lower roller, and the vertical adjustment can be carried out. In the upper part of the upper roller is provided with a rigid beam, between the beam and the upper roller is provided with a plurality of groups of rollers, in order to improve the rigidity of the upper roller; roll for ultra wide arc shaped parts.


The key technology and innovation point of three roller symmetrical marine bending machine:
Fully closed design to prevent dust from entering;
The ship with three roller symmetrical bending machine has convenient maintenance, high efficiency, long service life, good environmental protection effect and other advantages.

 

  1. The equipment is strong with all steel welded structure, and the use of computer finite element analysis method to optimize the design and calculation;
  2. Both ends of the shaft roller adopt adjustable ball bearing;
  3. The shaft roller is made of medium carbon steel after forging and quenching and tempering;
  4. Two bottom rollers have backup roll bending roll; Increase of the accuracy of the rolled workpieces and the whole machine performance.
  5. The machine adopts electric centralized control, simple operation, convenient;
  6. The console uses humanized design, easy and convenient operation;
  7. Centralized lubrication system.
