This is a regular upright rack production line, which can produce fixed size upright with high efficiency and high quality. 

Hydraulic decoiler

Given the thickness of the steel coil, we recommend the utilization of a hydraulic decoiler for efficient uncoiling. A press arm is set on the steel coil to prevent sudden unwinding. The entire decoiling process is powered by a hydraulic station, ensuring the coil remains securely in place to prevent any mishaps.

Leveler

The leveler can remove the uneven part of the steel coil, improve the flatness and parallelism of the steel coil, so as to improve the quality of the steel coil. Steel coils typically come with a thickness of 2-3mm, making a leveling machine essential. Standard leveling machines consist of 2 upper rollers and 3 lower rollers. However, to meet the specific leveling requirements based on the actual thickness, we have configured a leveling machine with 3 upper rollers and 4 lower rollers.

Servo feeder

Since the hydraulic punch itself doesn't provide the force to advance the steel coil, we have equipped a servo feeder to feed the steel coil into the punch machine. Additionally, the servo feeder is fitted with an encoder device that converts length into an electrical signal, allowing the feeder to accurately control the distance the steel coil advances. This ensures precise punching.

Hydraulic punch

At this stage, we can punch holes on the steel coil using the punch machine, guided by the  punching drawings to determine the punch dies and molds. Ultimately, these holes will appear at the bottom and high sides of the upright rack after roll forming. The hydraulic punch is a cost-effective option. However, for higher production speeds, a punch press is needed.

Guiding

Each machine in the production line must be carefully positioned to keep the steel coils aligned along the center line, to ensure that the upright rack is not deformed, and also to protect the machines. Therefore, simple guiding part plays a pivotal role. Multiple guiding rollers are strategically placed throughout the line to achieve this critical function.

Roll former

Taking into consideration the thickness of the steel coil, we recommend employing an integrated cast-iron structure and gearbox driving system. This ensures the stability and efficient operation of the roll forming machine. Customization of motors throughout the production line is available, as we prioritize clear communication with our clients to guarantee optimal machine performance.
