This upper roll of this machine not only can vertical fluctuation but also can level migration, the vertical fluctuation is the hydraulic transmission, it obtains the level migration through the hydraulic cylinder in hydraulic fluid act on connecting rod. Through the turbine bar box, the turbine wheel pole,the screw mandrel organization transmission torque, drives the upper roll the level migration,

Hydraluic 3-roller plate bending machine is a hydraulic three-roller bending machine and used to pre-bending of end of plate , rolling round,getting cone style and correct plate round as well as complete other processes at one feeding for all sorts of vessel carbon steel and low alloy steel plate as well as stainless steel under normal temperature without turning back.

4-roller plate bending machine,the main structure consists of upper roll, bottom roll, side roll, main drive device, tipping device, right and left supporting structure, and seat.The upper and the bottom rolls, which work as the main drive at the same time, provide drive by hydraulic motor. They may transfer normal-reversely to provide torque needs.The bottom roll lifts vertically, clamps bending plate by hydraulic cylinder

This series machine with hydraulic up-driving system can be run stably. The machine with nominal force less than 1000kN and worktable length less than 3200mm adopts double cylinders. Both mechanical stop controlling the stroke of sliding block and the back gauge can be adjusted manually and with digital read-out device.
 

Parameter: Upper roller force: 230 Tons Diameter of the upper roller: Φ420mm. Diameter of the lower roller: Φ235mm Central distance between bottom shafts: 380mm Max width of coiled plate: 3000mm Length of working rolls: 3100mm Max thickness of coiled plate,Symmetry coiling thickness: 25mm Asymmetry coiling thickness: 20mm Coiling speed: About 3.5m/min Capacity: Σs≤245Mpa
 

QC12Y Series Hydraulic Swing Beam Shear(Hydraulic shearing machine, cutting machine) MAIN FEATURES: 1. The frame adopts whole steel welded construction, which the internal stress is eliminated by vibration and heat treatment process. 2. It is adopted hydraulic driving, hold-down force will change according to the shearing force.
 

It adopts integrated hydraulic control systems which is more reliable and easy for maintenance. The hydraulic system consists of motor, oil pump and valve groups and it is installed at the top of the oil box. This can assure that the cylinder is always full of oil when the slide is moving down at high speed.And can save energy as the oil filling valve can guarantee the slide movement speed

Functions and Characteristics It can be sensitively operated and easily maintained with reasonable design and compact construction. With welded frame, stable performance, big cutting force, low noise and beautiful appearance. The hold-down pressure is very big but the surface of sheet-plate will not be damaged with butterfly spring hold-down device and non-metal unwearable hold-down washer.
