750-type floor decking machine

750-type floor decking machine

1. Working principle: The 750-type floor decking machine adopts cold roll-forming technology. Raw materials such as galvanized steel plates are gradually pressed into floor decking with specific cross-sectional shapes (such as V-shaped, U-shaped, trapezoidal or similar shapes) through a series of rollers. This forming method enhances the structural strength of the steel plate and can meet the load-bearing requirements of building floor slabs.
2. Equipment structure:
   • Machine body: Usually welded with section steel such as 350mm H-beam or 400H steel to ensure the stability and strength of the machine body and be able to withstand various stresses during equipment operation.
   • Rollers: Rollers are the core components of the equipment. Generally, high-quality steels such as 45# steel are used. After multiple processes such as forging, processing, and heat treatment, it is ensured that the rollers have sufficient hardness, strength, and wear resistance. The surface of the rollers is usually hard chrome-plated to improve their surface finish and wear resistance and ensure the forming quality of the floor decking.
   • Transmission system: Mainly composed of sprockets, chains, and reducers, etc., it is responsible for transmitting the power of the motor to the rollers and driving the rollers to rotate to realize the continuous rolling of the steel plate. The design of the transmission system needs to ensure the smoothness and accuracy of power transmission to ensure the forming accuracy of the floor decking.
   • Hydraulic system: Used to control the shearing action of the floor decking, including components such as shearing cylinders, oil pumps, and control valves. The hydraulic system can provide sufficient shearing force to ensure accurate shearing dimensions and flat cuts of the floor decking.
   • Control system: Adopting electrical components such as PLC (programmable logic controller) and frequency converter to realize the automatic control of the equipment. Operators can set the operating parameters of the equipment through the control panel, such as rolling speed and shearing length. The control system will automatically control the operation of the equipment according to the set parameters to improve production efficiency and product quality.
3. Technical parameters:
   • Forming speed: Generally 8-15 meters per minute. Different manufacturers’ equipment may vary, but a faster forming speed can improve production efficiency.
   • Applicable materials: Mainly applicable to galvanized steel plates, color steel plates, etc. The thickness of the material is usually between 0.8-1.5 millimeters, and the width is generally about 1000 millimeters.
   • Number of forming passes: Commonly 20-25. A larger number of forming passes can make the forming of floor decking more accurate and stable.
   • Motor power: The power of the main motor varies according to the size and production capacity of the equipment. Generally, it is between 22 kilowatts. The power of the hydraulic station motor is usually 4-5.5 kilowatts.
4. Product features:
   • Good structural performance: The produced floor decking is light in weight, high in strength, large in load-bearing capacity, and good in seismic resistance, which can meet the structural requirements of floor slabs in high-rise buildings and other buildings.
   • Convenient construction: The construction of floor decking is simple, fast, and easy to assemble, which can greatly shorten the construction period of buildings.
   • Good economy: It can replace traditional formwork, reducing the use and removal of formwork and reducing construction costs. At the same time, as the tensile reinforcement of the concrete floor slab, floor decking can save the consumption of steel bars and concrete.
   • Beautiful appearance: The surface of floor decking is flat, the dimensions are accurate, and the appearance is clean and beautiful, which is conducive to improving the overall quality of buildings.
5. Application fields: The floor decking produced by the 750-type floor decking machine is widely used in construction projects such as high-rise buildings, steel structure factories, and bridges as floor slabs and roof slabs.
