Product Detail Introduce
1.Automatic Decoiler with Loading Trolley
The machine is single support mode, motor driven uncoiler material shaft to release the material volume, hydraulic power drive uncoiler material shaft tensioning device, the material volume is fixed on the uncoiler material shaft,the tensioning structure is wedge type,more stable and reliable working condition
The uncoiler is automatic type , when the material after being installed on the uncoiler material shaft, in actual operation process of the whole line of decoiler material is active rotation axis, the traction from the uncoiler uncoiling mechanical and electrical machine can automatically according to the speed of the whole line for the release of the material in order to ensure the safety of decoiler operation decoiler is equipped with pneumatic brakes
The uncoiler also contains 4 baffle plates and a press arm to prevent the material from loosing in the uncoiling process and to ensure the safety of the operators
Coils ID：Ф508mm
Max. Coil OD：Ф1600mm
Max. Strips width：750 mm
Max. Coils weight：≤6000 kg
Uncoiler motor power：≈5.5kw（according the final design
2.Material Storage Devices
The material storage device consists of two parts: the arc-shaped idler roller and the material-supporting device. There are four sets of arc-shaped idler rollers, which are placed on both sides of the two storage bins, and are composed of an arc frame and a set of flexible idler rollers. , The surface of the roller is plated with hard chrome. A photoelectric switch is installed in the pit of the discharge bin to control the position of the material coil entering the pit, so that the speed of each working part can be perfectly matched
3.Special 400T hydraulic punching and cutting machine
It adopts hydraulic four-column press mode, economical and applicable, the speed of fast punching distance can be adjusted in the horizontal direction of the plate, and the punching distance can be changed through the electrical control system
4.Punching &Cutting composite
The punching machine is equipped with two complete sets of punching & cutting moulds .
Three-wave (beam) guardrail plate is equipped with a set of punching &Cutting mould, Can finish the punching 28 holes at end the guardrail and cutting in one time.The specific mold specifications shall be confirmed according to the punch drawing signed and confirmed by the buyer and the seller.
