Angle Steel Roll Forming Machine
Angle steel roll forming machines are specialized equipment designed for processing angle steel (a long strip of steel with two mutually perpendicular angular sides). They achieve processes such as bending, shearing, punching, and rolling of angle steel through a series of mechanical actions, playing a vital role in the metal processing industry. Here is a more detailed introduction:
Different types of angle steel roll forming machines vary slightly in structure, but their core components typically include:
– Frame: Serving as the basic framework of the equipment, it is welded from high-strength steel to ensure stability and rigidity during operation, reducing the impact of vibration on processing accuracy.
– Drive system: There are two common types: hydraulic drive and mechanical drive. The hydraulic drive system is powerful and outputs stably, suitable for heavy-duty processing of large-sized angle steel; the mechanical drive (such as a motor combined with gear transmission) has a fast response speed, making it more suitable for mass production of small and medium-sized angle steel.
– Roll forming working mechanism: This is the core part of processing, including multiple sets of roll forming rolls, molds, or pressure wheels. For example, the roll forming roll sets of a cold-bending roll forming machine, where each set of rolls is designed according to the cross-sectional size and roll forming requirements of the angle steel. By gradually adjusting the roll spacing and angle, the raw material is gradually bent into the desired shape; the bending machine is equipped with molds of different curvatures for bending angle steel into arcs, right angles, etc.
– Control system: Modern angle steel roll forming machines mostly adopt PLC (Programmable Logic Controller) combined with touch screen operation, which can preset processing parameters (such as bending angle, feeding speed, punching position, etc.). Some high-end equipment also supports CAD drawing import to realize automatic parameter setting and reduce manual operation errors.
– Auxiliary devices: Such as feeding mechanisms (to ensure uniform and precise feeding of raw materials), positioning devices (to ensure the accuracy of processing positions), cutting/shearing mechanisms (for cutting the roll formed angle steel to the set length), punching mechanisms (to process holes of specific specifications on the angle steel to meet assembly needs), etc.
Processing Flow (Taking Common Cold-Bending Roll Forming as an Example)
1. Raw material preparation: Coiled steel strips or fixed-length angle steel blanks are fed into the equipment through the feeding mechanism. Some equipment can automatically level the raw materials to ensure a consistent processing benchmark.
2. Progressive roll forming: The raw material enters multiple sets of roll forming roll sets. Each set of rolls locally bends or extrudes the steel according to the preset shape. Through the accumulation of multiple processes, the flat plate or steel strip is gradually processed into the cross-sectional shape of the angle steel (such as L-shape).
3. Auxiliary processing: According to requirements, operations such as punching, cutting, and marking (such as marking specifications and serial numbers) are performed during or after roll forming. These processes can be linked with the roll forming process through the control system to achieve integrated processing.
4. Finished product output: The processed angle steel is sent out through the conveyor belt. Some equipment is equipped with a stacking device to realize automatic stacking of finished products, facilitating subsequent handling and storage.

Classification and Application Scenarios
According to processing functions and application ranges, angle steel roll forming machine can be divided into various types:
– Cold-bending roll forming machine: Mainly used for cold-bending steel strips into angle steel, suitable for mass production of standard-sized angle steel, and widely used in steel structure buildings, shelf manufacturing, etc.
– Angle steel roll bending machine: Focuses on bending finished angle steel into non-linear shapes such as arcs and circles, for example, in the processing of bridge supports and pipe fixtures. It can be divided into horizontal and vertical types according to the bending method, and some equipment can achieve multi-angle and multi-radius bending.
– Multifunctional combined roll forming machine: Integrates multiple functions such as cold bending, punching, cutting, and bending, suitable for small-batch and multi-specification angle steel processing. It has high flexibility and is often used in machinery manufacturing, power tower production, and other scenarios.
– CNC angle steel roll forming machine: Adopts a high-precision CNC system with a processing accuracy of up to ±0.1mm, suitable for fields with high requirements on dimensional accuracy, such as aerospace and precision machinery supporting.
Advantages and Notes
– Advantages: Compared with traditional manual processing, angle steel roll forming machine have the characteristics of high production efficiency (capable of processing several meters per minute), stable processing accuracy, and low labor intensity. They can also adapt to the processing of angle steel of different specifications by replacing molds, with strong versatility.
– Notes: Before use, it is necessary to adjust processing parameters according to the material (such as ordinary carbon steel, alloy steel) and thickness of the angle steel to avoid workpiece deformation or equipment damage caused by improper parameters; regularly maintain and repair vulnerable parts such as roll forming rolls and molds to ensure their surface smoothness and prolong their service life; operators need to receive professional training, be familiar with the control system and safety operating procedures, and prevent safety accidents.
Angle steel roll forming machines have greatly improved the production efficiency and quality of angle steel through mechanized and automated processing methods, and are indispensable key equipment in the modern metal processing industry.
