  • Q Selection of Roller Material | Roll Forming Basics


    Selection of Roller Material 

    The general principle of selection of roll material is to fit to its application environment.
    No material is to fit all applications. The normal “good material” has its Specific working conditions and technical requirements.
    The wear resistance of a material not only depends on the material itself, but also has a great relationship with the wear conditions.?For the same material, the performance of different wear systems is quite different, and different working environments should use rollers of different materials.
    In the specific selection of roll material should be considered from the following aspects

    (1)The roller material should have high wear resistance and suitable hardness. 

    The abrasion resistance and hardness of the roll surface not only affect the service life of the roll but also affect the shape size and surface quality of rolled formed products.

    (2)The roller material should have sufficient strength and toughness. 

    if the roll only has high wear resistance and hardness, without good strength (including fatigue strength) and toughness, the roller in the roll forming process may break or surface peeling, crack, affect the reliability and safety of the roll.

    (3)The roller material must have certain cold machining and hot working performance

    Cold machining refers to lathes, grinders, milling machines, drilling machines and other processing, while hot machining refers to casting, forging and heat treatment
  • Q Classification Methods of Cold-roll formed profiles | Roll Forming Basics

    There is no unified regulation or agreement on the classification methods of cold-formed steel products. 

    Generally speaking, cold roll formed steel profiles can be classified  by the sectional shape characteristics of the products.

    By the section shape, they can be roughly divided into the following three categories: open section section, closed section section and wide section.

    1. open section section

    Example: Door Frame Profile, C-Punrlin, Racking Upright, Racking Beam

    2. closed section section

    Example: Box Beam, Downspout

    3. wide section

    Example: Roofing Panel and Wall Siding, Decking
  • Q How to check the roll forming machine quality good or bad? | Buy a Roll Forming Machine


    How to check the roll forming machine quality good or bad? 

    There are lots of things to consider when buying a roll forming machine. Here we only talk about same simply methods to indentify the roll forming machine quality good or bad?

    1. Look at the appreance of the roll forming machine.

    The first point is definitely to look at the appearance. You should carefully observe some subtleties, because the quality of the roll forming machine is often reflected in these small places.These details can reflect the manufacturer's level of technology and management.

    2. Touch and feel the vibration of roll forming machines.

    Normally a roll former with strong base means higher precision and longer life. Just feel the working vibration when roll forming machine running. It is an easy way to identify low quality equipment.

    3. Listen to the working noise.

    Normally a good roll former has lower noise when running.

    4. Check the roll formed profiles quality.

    Check the formed profiles, it is the most direct way to identify the roll former qualified or not. Although some of the equipment will deform after working for a period of time and the size of the product will change, at least it can be determined that the new equipment is still usable.

    5. Ask qustions about roll forming machine maintanence.

    A good design roll forming machine, from the beginning of the design, manufacturer has considering to minimize the installation and maintenance costs. e.g. center alignment, a good roll forming line is much easier to do the certer aligning in less time.

    6. Roller Materials

    Roller is a key part of roll forming machine, high quality roll not only means high precision machining, but also appropriate quality steel with professional heat treatment.
    The above are some small tips to check the roll former quality. We hope it is helpful for you to buy a new roll forming machine.
  • Q General Maintenance Guide for Roll Forming Machines | Roll Froming Machine Maintenance

    Keep the roll forming line in good working condition is Maintenance engineer's first priority, Keep each machine in the metal forming line running efficiently with shortest breakdown time. Maintain the machine running smoothly to reach a high level of productivity, it is save time and money for the company.
    1. The maintenance personals should be adequately prepared and qualified in maintenance operation of the roll forming machine
    2. Maintain the roll forming working area in order and clean. Roll dies should not bump. In order to protect the roller dies, the raw sheet metal should be relative flat without too much bending or foreign matters.
    3. Every day when starting up, first let the roll forming line empty run, after checking, then feeding metal coil and start production.
    4. Regular Lubricant to bearings, chains,guide rails in roll forming machines, oiled the machine at marked lubrication points.
    5. Maintain the hydraulic system of roll forming machine.
  • Q The advantages and disadvantages of roll forming | Roll Forming Basics

    Generally speaking, roll forming is a high-speed method of bending coiled metal into a custom designed metal shape by passing a metal strip through a series of roll dies. The process produces a metal profile with a uniform cross section along its entire length.
    The metal, which starts out flat, is fed from a coil into a configuration of roll die stations or passed. At each pass the metal is progrressively bend until the final profile emerges.

    The advantages of roll forming

    The advantages of roll forming are speed, economy of scale, the ability to eliminate and incorporate secondary operation such as punching and notching in-line, the ability to form both simple and complex shapes, and the ability to produce extra long shapes that can not fit into a brake press.
    1. Holding tighter tolerances
    2. quick change-over for multiple lengths
    3. minimize material handling
    4. save floor space
    5. standard shapes(such as U-channels, angles, hat sections, box channels) are often available with minimal or not tooling cost.

    The disadvantages of roll forming

    The process does not lend itself to small quantity production runs.
    1. set-up times can vary between a few hours to a couple of days.
    2. excessive set-up scrap
    Roll Forming VS Brake Forming
    Roll Forming Conventional Sheet Metal Fabrication
    Typically holds tighter tolerances Typically holds looser tolerances
    Inline punching,notching,etc - elimates secondary operation Mutiple operation required - shearing, notching, perforating, etc.
    Complex shapes Simple shapes
    Longer part lengths Most brake parts have limited length
    High-speed production Slower production speed
    Lower labor costs Higher labor costs
    Potentially higher tooling costs Potentially lower tooling costs
    Longer set-up time Shorter set-up time
    Potentially more scrap Potentially less scrap
