Fence post fixed-cut roll forming machine
Profile
Metal fence post is a commonly used type of fencing in Europe, resembling wooden plank fence post. It is constructed from 0.4-0.5mm color-coated steel or galvanized steel, offering high customization in shapes of shape and color. The end edges of the fence can be cut into oval shapes or kept straight.

Real case-Description
Decoiler
The core expansion device on the uncoiler allows for adjustment of the inner diameter to accommodate steel coils with inner diameters ranging from 460-520mm. Additionally, the uncoiler is equipped with two safety features: the press arm and the outward coil retainer. During coil replacement, the press arm secures the steel coil to prevent it from springing up and causing injury to workers. The outward coil retainer prevents the steel coil from sliding and falling off during unwinding.
Guiding
The guiding rollers will effectively direct the steel coil into the forming rollers, ensuring precise alignment between the coil and the roll forming machine, thereby reducing the risk of bending or deviation.
Roll forming machine
The roll forming machine is the key component of the entire production line. This machine features a wall panel structure for the forming station, with chain-driven forming rollers. The fence post is reinforced with multiple ribs to enhance its strength and protective capabilities. Additionally, edge folding on both sides of the post is completed on the roll forming machine to reduce sharpness and minimize the risk of scratches.
The forming rollers are made of Gcr15 material, a high-carbon chromium bearing steel known for its excellent hardness and wear resistance. The rollers are also chrome-plated to extend their lifespan. The shafts are made of 40Cr material and undergo heat treatment for durability.
Hydraulic cut
The cutting machine on this production line has a fixed base, causing the steel coil to stop moving forward during cutting. If you seek to increase production speed, we offer a flying cutting machine. In the “Flying” configuration, the base of the cutting machine can move forward and backward on the track at the same speed as the forming machine. This design allows for continuous advancement of the steel coil through the forming machine, eliminating the need to halt operation during cutting and thus enhancing the overall speed of the production line.
Hydraulic station
Our hydraulic station is equipped with cooling fans to efficiently dissipate heat, ensuring continuous operation and enhancing productivity. With a low failure rate and long-lasting durability, our hydraulic station delivers reliable performance.
PLC control cabinet & Encoder
The encoder converts the sensed length of the steel coil into electrical signals transmitted to the PLC control cabinet. Within the control cabinet, parameters such as production speed, individual production output, and cutting length can be controlled. With precise measurement and feedback from the encoder, the cutting machine can maintain cutting accuracy within ±1mm.
Stop to cut VS Non-stop to cut
In the cutting process, there are two options available:
Fixed cutting solution (Stop to cut): The cutter and roll forming machine base are fixedly connected. During cutting, the steel coil stops moving into the roll former. After cutting off, the steel coil resumes its forward motion.
Flying cutting solution (Non-stop to cut): The cutting machine moves linearly along tracks on the machine base, maintaining relative stillness with the cutting point. This allows the steel coil to continuously advance and produce.
Summary and recommendation:
The flying solution offers higher output and production speed compared to the fixed solution. Clients can choose based on their production capacity needs, budget and development plans. The budget permitting, opting for the flying solution can reduce future line upgrade hassles and offset the cost difference after getting higher output.
