The CZ purlin roll forming machine consists of three main parts, including the uncoiler, the forming station, and the section cutting part. It operates roughly in accordance with the following eight parts: manual uncoiler/hydraulic uncoiler → feeding guide → leveling → optional pre-punching and cutting pre-cutting → main roll mill → hydraulic post-cutting knife → PLC control system → discharge stand. This article will give a brief introduction to these parts of the CZ purlin roll forming machine.

Feeding and leveling device
The uncoiler of the CZ purlin roll forming machine with feeding guide and leveling device has seven axes of leveling device, arranged in the upper three and lower four. The mainframe of the uncoiler is made of welded H450 section steel with Q235 t30mm sidewall thickness. the shaft is made of 45# steel with φ120mm diameter. hard chrome plated coating and precise processing.
Perforating device
The punching device of the CZ purlin roll forming machine with four punching dies, a hydraulic motor is 37KW, and the hydraulic pressure range is 0-25Mpa. punching tool material uses die steel Cr12MoV, punching life is about 1 million times, heat treatment is HRC58-62 degrees. 2-cylinder punching device, a total of four punching dies are needed 19×64, 23×29, 20×65, and 24×30.
Main machine
Body frame made of welded H450 steel, rollers made of Cr12 steel, CNC lathe, the heat-treated shaft diameter of ф95, precision machined. Gearbox drive, upper and lower rollers with power. Adopt column structure design, cast iron memorial arch, thickness is 55mm. gearbox drive, about 19 stages forming. The main motor power is about 45 KW, using K series frequency conversion speed control reducer motor. The slider is 150*150mm and the bolts are all of grade 8.8 to ensure that the machine structure is fixed firmly. The machine can run for a long time and has a long service life, the actual molding speed is 12-16m/min. In addition, the CZ purlin roll forming machine is equipped with a water cooling device, which can produce better products.
Rear hydraulic cutting device
The post-hydraulic cutting unit requires a total of two cutting dies, a three-piece cutter design, and a 37KW non-falling hydraulic motor. One hydraulic station is shared with the punching unit and the cutting power is provided by a separate hydraulic station.
PLC control system
The CZ purlin roll forming machine adopts a PLC control system, which can automate the production process. The operator only needs to input production data on the touch screen, such as production batch, number, length, etc. The PLC control system can be completed in combination with an inverter, encoder, etc.
Outlet rack
The CZ purlin roll forming machine has an exit rack with rollers for easy movement of the finished product.
