Decoiler--Roll former--Hydraulic cut--Out table

7.5 Ton Hydraulic Decoiler

In this production line, we use a hydraulic decoiler with a load capacity of 7.5 tons. Producing trapezoidal panels requires wide steel coils, and the process of changing coils poses potential safety risks for workers. Additionally, protective iron leaves on the outer side of the coil prevent slipping during the decoiling process, with these design features prioritizing worker safety. 

An optional device: a loading car, assisting in transporting coils to the decoiler, saving time, and enhancing worker safety, especially in facilities without overhead cranes.

Roll Forming Machine

The roll forming machine is the most crucial part of this production line, featuring a total of 20 forming stations. It adopts a wall panel structure and chain driving system. The forming rollers are made of Gcr15, a high-carbon chromium-bearing steel known for its excellent hardness and wear resistance. Chrome plating on the roller surface extends the roller's lifespan, while the shafts are made of heat-treated 40Cr material.

Protective covers on the chain prevent dust buildup or fragments damaging the chains, also ensuring worker safety. The roll forming machine is tested using steel coils with the same yield strength as those used in customer production, providing convenience for production upon delivery.

Hydraulic Cut & Encoder

The roll forming machine incorporates a Koyo encoder from Japan, converting sensed steel coil length into electrical signals transmitted to the PLC control cabinet. This allows the cuttiing machine to control cutting errors within 1mm, ensuring high product quality and minimizing waste from incorrect cuts. The hydraulic cutting machine obtains powerful cutting force from the hydraulic station. The cutting process produces no waste, and the cut edges are smooth without burrs. We will test the roll forming machine until it can produce the profile matches the drawing. And then we will produced the matched blade molds based on the sample. Although this approach may slightly increase both time and labor costs, the cutting machine produced in this manner exhibits exceptionally smooth edges without any burrs.

Hydraulic Station

Our hydraulic station is equipped with cooling electric fans, aiding efficient heat dissipation for continuous and cool operation, contributing to increased work efficiency. The hydraulic station boasts a low failure rate and long-term durability.

PLC control cabinet

Workers can control production speed, set production dimensions, cutting lengths, etc., through the PLC screen. The PLC control cabinet includes protective functions such as overload, short circuit, and phase loss protection. The language of the PLC screen can be customized in a certain language or multiple languages according to customer needs.

Regular Out Table & Optional: Auto Stacker

For the transporting productions, a regular out table is available, non-powered, customizable in length and width according to customer needs.

However, when the length of the trapezoidal panel exceeds 6m, considering the width and weight of the panel, we recommend using an auto stacker to reduce manual labor costs and enhance overall efficiency and work safety. After cutting, the trapezoidal panels are conveyed to the stacker's swing arm, gently layering the panels. And then, the panels are transported outward along the conveyor.

Other optional: Ink printer

Customers can use the ink printer to print company name, logo, profile number, and other information on the panel surface. It can help companies quickly expand their markets and increase their visibility. The ink dries quickly and will not contaminate the surface.

Warranty

Before delivery, the delivery date is indicated on the nameplate, starting a two-year guarantee for the entire production line and a five-year warranty for rollers and shafts.
