Hydraulic uncoiler

Hydraulic uncoiler, with the support of the coil plate and provide tension to the steel belt, is composed of a frame, spindle, 

expansion and contraction drum, brake device of the uncoiler.

Basic structure of hydraulic uncoiler

A. Main frame: made of section steel, A3 steel plate and no. 45 steel forging and batching bearing block after welding, 

which will not deform after qualitative treatment by annealing; Two bearings are bored at one time to ensure the concentricity of spindle installation, without producing radial runout.

B. Spindle: it is made of 40Gr round steel drill with a diameter of 85mm through hole, and refined after quality adjustment. 

The working face has a diameter of 190mm and can bear 15 tons.

C. Stretch and shrink drum: it adopts the form of sliding block push and pull expansion drum; 

Four pieces of curved plates, wire cut slide, 460 ~ 520 Ф increases and the diameter Ф; The effective working length is 1300mm. 

The integral mandrel ensures the concentricity of the drum when it expands and shrinks. The surface of the drum is plated with hard chrome.

D. Brake device: pneumatic disc brake assembly is adopted, with adjustable braking force. 

The brake is tight when stopping and the brake is running when starting.

E. hydraulic power, push and pull up shrinking core axis: hydraulic cylinder model 

specification: FA - Ф 125 x 130 mm, the rotary joint drainage way; Pressure is expected to lift hydraulic cylinder FA - Ф 63 x 600 mm.
