Fire Cabinet Door Panel Roll Forming Machine
The Fire Cabinet Door Panel Roll Forming Machine is the core rolling equipment in the fire cabinet door panel production line. It is specifically designed to continuously form the reinforcing rib structure and folded edge contour of the fire cabinet door panel by passing steel strips through multiple progressive rolling passes. The equipment uses Cr12 hardened rollers (HRC58°-62°), PLC control, frequency conversion drive, power 30kW, speed 0-4 pieces/minute, and can process plates with a thickness of 0.5-1.5mm and a width of 100-1000mm, providing high-precision door panel blanks for subsequent glass window installation and bending processes.

Product Advantages
I. Multi-pass progressive rolling for flat, non-distorted thin-plate door panels
Fire cabinet door panels commonly use 0.5-1.0mm thin plates, which are prone to wavy edges and distortion during forming. The equipment employs a multi-pass progressive rolling process, with evenly distributed deformation in each pass. The steel strip gradually deforms, avoiding stress concentration on the plate surface caused by large-scale deformation at once. This ensures good flatness and straight edges, providing a flat foundation for subsequent glass window installation.
II. Cr12 hardened rollers for zero scratches on the plate surface
As an exterior component of the fire cabinet, the door panel requires high surface quality. The rollers are made of Cr12 die steel with a hardness of HRC58°-62°, and the surface is precision ground for excellent smoothness. The rollers effectively protect the plate surface as the thin plate passes through, leaving the galvanized layer free of scratches and indentations. After forming, it can be directly sprayed without grinding or repair.
III. One-time forming of window frame folding
When installing glass windows on fire cabinet door panels, the window frame needs a positioning folding or flange structure. The equipment forms the window frame installation folding edge in one step during the roll forming process. The folding edge angle is accurate and the width is consistent, and it fits tightly with the standard window frame profile, eliminating the need for subsequent secondary processing of the folding edge.

FAQ
Q: Are you a factory or a trading company?
A: We are a factory located in Weifang, China. It possesses over twenty sets of advanced equipment, including a new precision machining center, NC lathes, CNC wire EDM machines, and a large automotive profile bending test platform. You are welcome to visit our factory at any time.
Q: Do I need to replace the rollers when changing the equipment to produce different specifications of door panels?
A: For the same type of door panels with different widths and thicknesses, you can simply adjust the splitting and fine-tuning of the parameters.
Q: Will there be any marks on the back of the door panel after the reinforcing ribs are formed?
A: No. The equipment uses support rollers for forming, and the back of the reinforcing ribs has corresponding support during forming, so no dents or marks will be produced. The front of the door panel is flat, and the reinforcing ribs on the back are clearly visible. Both the front and back appearances meet the requirements for fire box door panels.
