18 Rows Trapezoidal Roll Forming Machine with 0-40 m/min Production Speed and ±1 mm Length Tolerance for Trapezoidal Sheet Forming Machine Production

The YX21‑164‑820 roll forming production line is a high‑speed, heavy‑duty automatic metal roof panel production machine. Built on mature cold roll forming technology, its complete workflow covers decoiling, guiding and feeding, roll forming, fixed‑length cutting and finished panel output. It efficiently produces high‑quality 820‑effective‑width color steel roof panels and is an ideal production solution for building material factories, steel‑structure manufacturers and metal processing enterprises.

Designed and assembled by Dongguang Hengfu Roll Forming Machine Co., Ltd., this production line uses a gear transmission structure for stable power transfer. Optimized for high‑speed continuous industrial production, it balances fast running speed, stable forming quality, convenient operation and low maintenance cost, delivering excellent comprehensive benefits for mass production of roof panels.

The whole machine is built on a heavy‑duty 350H steel welded wall‑plate frame with thick carbon‑steel wall panels. The solid main shaft and 18‑pass forming stations greatly enhance overall rigidity. Even under long‑hour, heavy‑load, non‑stop production, the frame will not deform and forming accuracy remains consistent.

All forming rollers undergo complete precision machining plus surface quenching‑tempering and electroplating treatment. The rollers feature high hardness and outstanding wear resistance, effectively extending the service life of key forming parts. Gear‑driven transmission delivers smoother and more powerful output than traditional chain drive, reducing running jitter and guaranteeing a uniform panel forming effect.

Equipped with high‑power servo motors for both the forming and shearing sections, the machine supports fast, adjustable production speed. The double linear‑guide servo electric shearing unit runs stably and delivers burr‑free, clean cutting without secondary trimming work. It offers a low failure rate and reduced maintenance.

A high‑precision length measuring device ensures outstanding dimensional repeatability. Every finished roof panel keeps a unified profile and precise length. Neat panel connection during installation effectively avoids hidden troubles such as roof water leakage. A warning alarm light provides timely feedback on production status and facilitates on‑site workshop management.

This production line is fitted with a proven split‑type PLC touch‑screen control system. Operators can easily set target panel length, production quantity and operating speed on the intuitive touch interface to realize fully automatic cyclic production. It does not require highly skilled workers; new operators can master daily operation after a short training period.

Complete safety configurations, including a foot‑pedal emergency stop switch, improve workshop operation safety. The equipment fits a 380V 50Hz three‑phase industrial power supply, adapting to most factory power conditions worldwide.

The machine processes standard color‑coated steel sheets. It handles material thickness within a reasonable range and produces well‑formed YX21‑164‑820 trapezoidal roof panels. Finished panels feature high structural strength, a tidy surface and good weather resistance. They are widely applied in steel‑structure workshops, large warehouses, commercial buildings, agricultural sheds and various construction roofing projects.
