सीधे डोर फ्रेम रोल फॉर्मिंग मशीन का कार्य सिद्धांत

The working principle involves rotary bending and sequential shaping of metal coil strips through consecutive roller dies to gradually form a door frame cross-section.

Key aspects include:

• Cold forming avoids heating/welding distortions
• Automated process ensures high outputs
• Specialized tooling packages for profile features
• Integrated hardware punching, notching, hole adding
• Precision calibration and straightening

These capabilities enable efficient mass production of dimensional and functional ready-to-install door frames.

Straight door jamb roll former classifications include:

Table 1. Major Equipment Specifications

Common line items:

• Decoiler and feeder system
• Forming stations with quick change tooling
• Punching/hardware insertion presses
• Welding for seam locks or reinforced frames
• Cutoff shear for batched lengths
• Exit conveyors and bundling

उत्पादन प्रक्रिया

The automated roll forming production sequence comprises:

1. Metal coil loaded on powered decoiler
2. Strip fed through feed guides into start of line
3. Sequential forming stations shape profile
4. Hardware notching/punching insertion
5. Corner welding for strength
6. Flying cutoff shears cut to length
7. Exit conveyor stacks finished frames

The process allows high volume precision part making with minimal manual labor between steps. Operators simply maintain equipment settings and offload finished door jambs.

अक्सर पूछे जाने वाले प्रश्न

Q: What types of door frames can roll forming lines produce?

A: Common models include single/double rabbet, knocked down, welded, profiles from wood door frames to heavy duty industrial.

Q: Can decorative patterns be added to roll formed door jambs?

A: Yes, aesthetic elements like embosses, textures and wood grain effects can be incorporated into profile tooling along with protective coatings.

Q: What is the typical production rate for door frame lines?

A: Output speeds vary based on width and thickness but approx. 10-20 finished door frames per minute is standard. Larger profile capacities hit 30+ per minute rates.

Q: How long does forming tooling last on door frame roll lines?

A: At 2 shift production volumes, tooling sees maintenance every ~3-4 months. Roller lifespan averages 100,000 feed meter cycles before needing replacement.

Q: Can door frame ends be notched before rolling?

A: Yes, rotary power notchers allow hardware voids and other edge features to be added even before the actual roll forming stations.

Q: Are knockdown roll formed door jambs as strong as welded?

A: Welded corners provide 30-40% higher frame strength but mechanical joints suffice for typical installations. Knockdown allows easier transport.
