Automatic hydraulic decoiler for metal roofing sheet rolling forming machine

Automatic hydraulic decoiler for metal roofing sheet rolling forming machine is designed for supporting metal rolling machine work. A hydraulic uncoiler, which supports the rolling plate and provides tension to the steel strip, is composed of a frame, a main shaft, an expansion and contraction drum, and a braking device.

1. a) 主框架:轴承座由型钢、A3 钢板和 # 45 钢锻造焊接而成，并经过退火和定性处理，不变形；两个轴承座同时镗孔，以确保主轴安装的同心度并防止径向跳动。.
2. b) 主轴:由 40Gr 圆钢钻头制成，通孔直径 85 毫米，经过淬火和回火处理，然后进行精细车削。工作面直径为 190 毫米，承重能力为 15 吨。.
3. c)Expansion and contraction shaft滚筒：采用滑块式推拉膨胀滚筒形式；四块弧形板和一对线性切削滑块，直径可增减 Ф 460~ Ф 520；有效工作长度为 1300mm，整体心轴确保滚筒在膨胀和收缩过程中的同心度。滚筒表面电镀硬铬。.
4. d) 制动装置制动器：采用气动盘式制动器组件，制动力可调。停车时拉紧制动器，行驶时拉开制动器，以确保在待机和启动状态下不会松动，避免松动时划伤板面。.
5. e) 液压动力：push pull expansion and contraction mandrel: hydraulic cylinder model and specification: FA- Ф one hundred and twenty-five × 130mm, using rotary joint oil supply method; Pressure lifting hydraulic cylinder FA- Ф sixty-three × 600 mm.

Automatic hydraulic decoiler for metal rolling forming machine types:

The hydraulic automatic decoiler has the following types:

1. The decoiler with short shaft for purline rolling forming machine.
2. Long shaft for wide coil roofing sheet machine
3. Hydraulic decoiler for slitting or cut to length machine.
4. Automatic decoiler for roofing sheet machine.

By the different functions and then the hydraulic decoiler we can design them like:

1. Fixed type decoiler
2. Movable hydraulic decoiler for many machines.
3. The loading car is fixed type
4. Or X table loading car
5. The decoiler withe pressing arm.
6. The decoiler with the supporting table.
7. The decoiler with the brake.

Advantages of Zhongtuo hydraulic decoiler:

1. Electrical parts: Equipped with world famous brand “Schneider”electrical parts, more safety and reliable.The operation of the equipment is more safe, reliable and stable.
2. Pneumatic braking system: Can stop the rotate of coil immediately when required, avoid unnecessary coil output.

Fast braking, more safer. The matching high-speed forming machine needs faster uncoiling speed, and the pneumatic brake can provide greater braking force. Customers need to be equipped with their own compressed air source.

3. Expanding device:Four arms expanding device with sliding block can provide more powerful force to fixing the coil, The synchronous action can avoid the deformation of the coil.  The block installed on the the arms can suit the coils with bigger inner diameter.
4. Limit Switch Arm. And rollers on frame. It can automatically start and stop the rotate of coil according to the rate of progress of forming machine.It can also be installed the other side of the machine for opposite feeding direction. we have reserved the installation bracket. The rollers on the both sides of  frame can avoid scratch of coil when it run out.

1. X table hydraulic decoiler.  
2. The decoiler movable type with rail

The rail length we can design according to your requirement like 6 meter 8 meters or others. By the movable type,it could be used together with many rolling forming machines. And then you can save lots of cost and space.

For the hydraulic decoiler we can make it to 5 ton, 7 ton  7 ton , 10 ton 15 ton 20 Ton and more, fully design according to your requirements. For more information, please contact us at any time.
