C Z Interchangeable Purlin Roll Forming Machine – One Machine, Two Profiles

The C/Z Interchangeable Purlin Roll Forming Machine, also known as the CZ integrated machine or C/Z interchangeable press, is a highly automated cold bending forming equipment that combines a C-shaped steel machine and a Z-shaped steel machine. This device can produce steel structural profiles with two different cross-sections, C-shaped purlins and Z-shaped purlins, through the same forming system, completely changing the traditional history of using two different devices to process C-shaped steel and Z-shaped steel separately.

This equipment uses galvanized steel coils, cold-rolled steel coils, or hot-rolled steel coils as raw materials, and processes metal coils into finished purlins in one go through a series of continuous processes such as feeding, leveling, forming, punching, and cutting. The entire production line usually consists of passive feeding racks, leveling devices, forming machines, punching devices, cutting devices, hydraulic stations, and PLC computer control systems.

Application scenarios：

The C-shaped steel and Z-shaped steel purlins produced by the C/Z interchangeable purlin forming machine are the core load-bearing components in steel structure buildings, widely used in the following fields:

1. Industrial plants and storage facilities
This is the biggest application area of the device. C-shaped steel is commonly used as wall purlins and secondary beams to support the outer protective structure of the factory building; Z-shaped steel is particularly suitable for large-span roof purlins and supporting color steel tile roof systems due to its ability to overlap and overlap. Specifically, it includes:

• Steel structure factory building, production workshop

• Logistics warehouses and industrial storage facilities

• Locomotive hangar, aircraft hangar

• Large public buildings such as exhibition halls, sports halls, cinemas, etc• 

2. Civil and commercial buildings

• Roof and wall support systems for commercial complexes and office buildings

• Light steel keel and skeleton structure for residential projects

• Structural purlins for prefabricated and modular buildings

• The skeleton of container houses

Core Features：

1. C/Z quick exchange, one machine with multiple uses
In traditional purlin production, C-shaped steel and Z-shaped steel need to be processed by two different equipment, which not only requires large equipment investment but also occupies a large amount of factory space. The C/Z interchangeable purlin forming machine achieves rapid switching between C-type and Z-type through innovative forming device design, including structurally symmetrical front and rear forming rollers and conversion components.

Flexible and diverse changeover methods: Fully automatic models can complete C/Z interchange with one click control through PLC, and changeover time only takes 1-3 minutes; Semi automatic or manual models can be replaced by adjusting the distance between the upper and lower rollers, positioning bolts, and flipping brackets, which is simple to operate and has a low failure rate. Regardless of the method, there is no need to replace the forming rollers during mold changing, greatly reducing mold changing time and labor costs.

2. Infinite changeover, adjustable size at will
The advanced C/Z interchange equipment is equipped with a stepless transformation system, which can be adjusted to any size within the specification range in units of 1 millimeter. Taking C-shaped steel as an example, the width of the web plate can be freely adjusted between 80-300mm, and the height of the flange can be freely adjusted between 40-80mm; The web plate of Z-shaped steel can be freely set within the range of 120-300mm.

This "infinite" feature not only supports the production of standard specifications, but also meets customers' customized needs for non-standard board shapes. At the same time, the infinite cutting system achieves cutting without changing the tool after forming, and shares the tool when switching between different specifications, further improving production efficiency and equipment utilization.
