Many people don`t know how to distinguish between the stretch
Bending Machine and the
Roll Bending Machine, and how to choose between the two. In fact, the difference between the two is very large, and the overall concept and principle are different. This mainly depends on what product the user wants to make , let`s popularize the basic principles and usage plans of the two first.
Definition:
Stretch bending machine: After changing the extension of the profile, it pulls the deformation point of the profile and leans on the template to form an arc. The process methods include template rolling, tension adjustment, extension calculation, rebound calculation, stretching speed, boom angle, single-arm stretch bending , arms bent.
Roll bending machine: It is a kind of cold bending equipment for metal profiles, and it is a commonly used bending machine for aluminum alloy profiles, such as angle steel, channel steel, I-beam, metal square tube, metal round tube and various metal special-shaped profiles. Machinable shapes are circle, arc, ellipse, parabola and so on. It can be divided into vertical and horizontal, easy to operate, low cost, suitable for cold bending of small and medium-sized profiles.
Application:
Stretch bending machine: aluminum doors and windows, automobile luggage racks, automobile high-speed rail structural parts, elevator handrails, yacht structural parts, stainless steel pipes for bathrooms, etc., widely used in high-speed trains, automobiles, ships, large buildings, bridges, wind power, aviation and other high-end fields .
Roll bending machine: used in the production of circular flanges in automobiles, aerospace, rail transit elevators, conveying guide rails, doors and windows, curtain walls, decoration engineering, ships, lighting, etc. and other industries.
Stretch bending machine is suitable for hollow and flat profiles, and roll bending machine is suitable for heterogeneous materials, super heterogeneous materials, arc-shaped materials, such as bread tubes, round tubes, oval tubes, window materials, etc. Sometimes we fall into a misunderstanding, thinking that stretch bending machines and rolling bending machines are the same thing. In fact, there is a lot of knowledge in it. The industry of bending and rounding is a knowledge that can never be learned. There are many unseen profiles and many asymmetric profiles that need us to understand and solve. Therefore, knowledge is inexhaustible and learning is endless, and experts in the industry need to face and solve it together.
