2-3-wave W-beam LW750 guardrail Cold Roll-forming Mill

This production line is our company developed guardrail plate and shaped steel special equipment, with a certain specification of steel strip as raw materials, through the cold forming method, the production of the required specifications of cold formed steel. The unit has innovative design, convenient operation and maintenance, that is, saving investment and economical and practical, typical material galvanized steel, low carbon steel (IS2062-GR-E350). Our company shall be responsible for the overall design, manufacturing, guidance, installation and commissioning of the production line.

Single arbor hydraulic uncoiler, the power is a individual three-phase motor. It is also with the brake device, the uncoiling speed can be controlled by frequency conversion. The swaying pole control the location of the material, the photoelectricity switch is fixed at the end of the swaying pole. The uncoiler can make uncoil the material forward and reversal. It has a independent hydraulic system, it is with a pressing arm device.

There are pairs of nipping and sending roller. Flatten rolls are arranged for two top and three below. Nipping and sending is pressured by hydraulic cylinder, flatter roll motor is cogged by worm wheel and worm screw reduced speed, the worm screws in front and one in back can come true be in-phase by sleeve connecting, which can ensure top leveling roll and under leveling roll be parallel, thereby which reach in the intention of flatten.

In order to ensure the accurate position of the strip before entering the punching machine, a neutral roll frame is provided, and the first group completes the punching into the servo feeding mechanism, equipped with pneumatic compression and encoder speed measurement device, so that the punching position is more accurate.

Forming mill consists of 18sets horizontal roll stand, The horizontal stands are cast steel structure.

Function: cut profile without stopping. Servo motor drive tracking cutting machine,Insert and blank cutting. 

Structure features: servo drive, touch screen set length, cutting under the control of PLC, tracking profile discharge running speed, when the two speed synchronization, reach the set length, hydraulic cylinder action driven to cut the mold, cut the profile. After cutting off, cutting machine reset.

  Features: high slitting precision, stable operation, and strong material adaptability.

 Advantages: high production efficiency, uniform strip width, automated control, and low material waste.

 Key parameters: coil width/thickness range, slitting speed, number of slitting blades, and strip width tolerance.
