डोर फ्रेम रोल फॉर्मिंग मशीनें 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
- उच्चतर उत्पादन दरें
- कम श्रम आवश्यकताएँ
- सुसंगत गुणवत्ता और सटीकता
- 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.
कैसे डोर फ्रेम रोल फॉर्मिंग मशीनें कार्य
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…
डोर फ्रेम रोल फॉर्मर के प्रकार
There are two main categories of lines for roll forming door frame profiles:
प्रकार 1: स्वचालित कट-टू-लेंथ रोल फॉर्मिंग लाइनें
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.
मुख्य घटक: Decoiler, guiding rolls, forming stations, cutting unit, PLC control
लाभ: High degree of automation, consistency, and efficiency
प्रकार 2: परिवर्तनीय लंबाई वाली रोल फॉर्मिंग मशीनें
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.
मुख्य घटक: Decoiler, forming stations, pinch rolls, manual cutting post-production
लाभ: Flexibility in production planning, lower cost
रोल फॉर्मर के प्रकारों की तुलना
| पैरामीटर | Type 1 Cut-to-Length | Type 2 Variable Length |
|---|---|---|
| Automated Cutting | हाँ | No, manual post-production cutting needed |
| Length Flexibility | Low, fixed cut sizes | High, continuous lengths produced |
| प्रक्रिया नियंत्रण | High degree via PLC | Medium, manual monitoring required |
| उत्पादकता | Higher, efficient inline process | Lower, additional processing step |
| Equipment Costs | Higher due to cutting unit | Lower without built-in cutting |
रोल फॉर्मिंग मशीनों की कार्य प्रक्रिया
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. फॉर्मिंग
- 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
