18 Forming Stations Trapezoidal Roll Forming Machine with 0–40 m/min Production Speed and ±1 mm Length Tolerance for Trapezoidal Roof Panel Machine Lines

The YX21‑164‑820 roll forming production line is a high‑speed, heavy‑duty automatic metal roof panel machine from Dongguang Hengfu Roll Forming Machine Co., Ltd. It is designed for building material factories, steel structure manufacturers and metal processing enterprises that require stable mass production of trapezoidal roof panels. The equipment integrates coil decoiling, material guiding, roll forming, fixed‑length shearing and finished panel output into one fully automatic process, helping customers improve production efficiency and ensure consistent product quality.

The machine adopts a heavy‑duty 350H steel welded wall‑type frame, thick carbon steel wall plates, a solid main shaft and 18 forming stations. This reinforced structure greatly improves overall rigidity and reduces deformation during long‑hour heavy‑load operation, helping maintain stable forming accuracy and product consistency.

All forming rollers are precision machined, tempered and electroplated, providing high hardness and excellent wear resistance. The gear transmission system delivers smoother power output than traditional chain drive, reduces high‑speed vibration and ensures more uniform panel forming quality.

Both the main forming unit and the shearing unit are equipped with high‑power servo motors, enabling stable and adjustable production speed. The machine can adapt to different order sizes while maintaining reliable forming quality, making it suitable for both small‑batch production and large‑volume industrial orders.

The double linear‑guide servo electric shear runs smoothly and produces clean, burr‑free cuts without secondary trimming. This improves finished product quality and reduces manual maintenance work, helping customers achieve more efficient production.

A high‑precision length measuring device ensures accurate dimensions and good repeatability. Each finished roof panel has a consistent profile and precise length, which helps achieve tighter overlap during installation and reduces the risk of roof leakage. The warning alarm light provides clear production status feedback and improves on‑site workshop management.

The machine is equipped with a split‑type PLC touch screen control system. Operators can easily set panel length, production quantity and running speed through the intuitive interface, and realize fully automatic cyclic production. The operation logic is simple, so workers can master daily operation after short training.

Safety devices such as the foot‑pedal emergency stop switch provide better protection for operators. Designed for a 380V 50Hz three‑phase industrial power supply, the YX21‑164‑820 can adapt to most common factory power environments.

The YX21‑164‑820 is suitable for processing standard color‑coated steel sheets within a reasonable thickness range. It produces high‑quality trapezoidal roof panels with high structural strength, a neat surface and good weather resistance. The finished products are widely used in steel structure workshops, large warehouses, commercial buildings, agricultural sheds and various construction roofing projects.
