Elevator Guide Rail Making Machine Guide
| Type | Description |
|---|---|
| Roll forming machine | Continuously forms metal coils into customized rail profiles by progressively bending sheet through series of roller dies |
| डेकोइलर | Feeds metal coil strip into roll former |
| Pre-cutting shears | Trims sheets to required coil width before forming |
| Roll forming stands | Successive stands with roller dies to incrementally bend metal strip |
| Post-cutting shears | Cuts formed rails to required lengths |
| Supporting equipment | PLC control, hydraulics, gearboxes, instruments |
Elevator Guide Rail Making Machine Working Process
The elevator guide rail making machine works by roll forming process. The input raw material is steel coil loaded on an uncoiler. The coil passes through pre-cutting shears where it is trimmed to the specified width required for the rail profile.
The trimmed metal strip then proceeds through successive roller dies mounted on forming stands. Each set of rolls progressively bends the sheet incrementally to gradually form the desired rail configuration.
The fully formed rail profile exits the last stand of rolls and is cut to desired lengths by post-forming shears. The finished cut rails are collected on the outfeed tables.
