Door frame roll forming machines are equipment used to automatically bend metal coils into customized door frame profiles. This equipment is versatile, efficient, and delivers quality end products for door frame manufacturing.
Roll formed door frames have several benefits compared to traditional fabrication methods:
- More uniform profile dimensions
- উচ্চতর উৎপাদন হার
- Lower labor requirements
- Consistent quality and precision
- Flexibility to create custom frame designs
This guide will cover the working process, types, features, parameters, applications, operation, suppliers, costs, pros/cons, and FAQs about door frame roll forming lines.
How Door Frame Roll Forming Machines Work
The roll forming working principle involves feeding metal coil strips through a series of roller dies to shape the material incrementally into chosen frame cross-sections…
Types of Door Frame Roll Formers
There are two main categories of lines for roll forming door frame profiles:
Type 1: Automatic Cut-to-Length Roll Forming Lines
These systems roll form the metal coil into door frame sections of fixed length as per order requirements. They incorporate a cutting unit to automatically cut profiles to customized sizes.
মূল উপাদানসমূহ: Decoiler, guiding rolls, forming stations, cutting unit, PLC control
সুবিধাসমূহ: High degree of automation, consistency, and efficiency
Type 2: Variable Length Roll Forming Machines
These roll formers produce frame profiles in continuous lengths rather than fixed sizes. They require manual cutting post-production to cut sections at desired lengths.
মূল উপাদানসমূহ: Decoiler, forming stations, pinch rolls, manual cutting post-production
সুবিধাসমূহ: Flexibility in production planning, lower cost
Comparison of Roll Former Types
| প্যারামিটার | Type 1 Cut-to-Length | Type 2 Variable Length |
|---|---|---|
| Automated Cutting | হ্যাঁ | No, manual post-production cutting needed |
| Length Flexibility | Low, fixed cut sizes | High, continuous lengths produced |
| Process Control | High degree via PLC | Medium, manual monitoring required |
| উৎপাদনশীলতা | Higher, efficient inline process | Lower, additional processing step |
| Equipment Costs | Higher due to cutting unit | Lower without built-in cutting |
Working Process of Roll Forming Machines
The step-by-step working methodology to create door frames on these machines involves:
1. Material Feed
- Decoiler feeds metal coil strip into roll former
- Guide rolls straighten strip
2. Forming
- Sheet passes through series of roller dies
- Rollers bend strip incrementally
- Profile is gradually formed across stations
3. Door Frame Design and Dimension
- Roller dies customize frame design and dimensions
- Various cross-sections like rectangular, round, etc. achieved
4. Cutting (for Type 1 machines)
- Cutting unit sizes profiles at fixed lengths
- PLC automatically sets cut lengths
5. Output
- Formed door frames collected at the end
- Manual bundling and storage follows
