Flying Shear Line

The core advantage of the flying shear line lies in its dynamic synchronous shearing capability, which enables the synchronization of "continuous material conveying" and "precision shearing". This completely breaks the traditional intermittent processing mode of "material stopping - shearing - material feeding" and significantly improves production efficiency:

Strong adaptability to processing speed: For metal strips and plates (such as cold-rolled steel plates and aluminum strips), it can be matched with high-speed conveying lines with a speed of 30-150 meters per minute, and the maximum shearing frequency can reach 5 times per second.

The flying shear line has strong scenario adaptability. Through parameter adjustment and module upgrading, it can cover the processing needs of different materials and specifications, avoiding the limitation of the equipment being "single-purpose":

Wide adaptability to materials: It can process metal materials such as carbon steel, stainless steel, aluminum and copper, as well as some high-strength plastic plates and composite materials. The processing type can be switched only by replacing the special cutting tool;

Wide adjustable range of specifications: The shearing length can be steplessly adjusted within 50-3000mm, and the shearing width is suitable for coils of 300-2000mm. It can realize the production of multi-specification products without replacing the mold, and is especially suitable for flexible production scenarios with small batches and multiple batches.

I. Core Classification of Flying Shear Line Products

Based on the differences in processed material forms, shearing processes and application scenarios, flying shear lines can be divided into the following main categories. Products of different categories have obvious differences in structural design and functional focus:

Classified by Material Form

Strip Flying Shear Line: Specifically designed for metal strips (such as cold-rolled steel strips and aluminum strips). Its core feature is equipped with a high-precision tension control system, which can prevent the strip from wrinkling or stretching deformation during high-speed conveying. The length deviation of the finished product after shearing is controlled within ±0.1mm, and it is widely used in metal plate processing and production scenarios.
Plate Flying Shear Line: Used for processing single plates (such as stainless steel plates and copper plates). It integrates a plate leveling unit, which can eliminate the internal stress generated during the material rolling process. The shearing width is suitable for 300-2000mm, and it supports mixed processing of plates with multiple specifications. It is often used in the production of precision hardware parts and electronic equipment casings.
Bar/Tube Flying Shear Line: Mainly used to process metal bars and tubes with circular, square and other cross-sections. It is equipped with a special clamping mechanism to prevent the material from rotating during processing. The shearing length can be steplessly adjusted within 50-3000mm, and it is suitable for the processing of products such as construction steel bars and mechanical transmission shafts.

Classified by Shearing Process

Cold Shear Flying Shear Line: Performs shearing operations in a normal temperature environment without preheating the material. The cutting tools are made of high-speed steel (HSS), which is suitable for materials with good plasticity such as low-carbon steel and aluminum alloy. It has the advantages of low energy consumption and high processing efficiency, and its daily output is 20%-30% higher than that of hot shear lines.
Hot Shear Flying Shear Line: Designed for high-temperature hot-rolled materials (such as hot-rolled steel billets). It is equipped with high-temperature resistant conveying rollers (capable of withstanding 800-1200℃ high temperature) and a cooling system. The shearing unit uses heat-resistant alloy cutting tools, which can effectively avoid damage to the equipment caused by high temperature. It is mainly used in the hot-rolling production lines of the metallurgical industry.

II. Key Points for Installation and Maintenance of Flying Shear Lines

As a high-precision automated equipment, the installation accuracy and daily maintenance of the flying shear line directly affect its operation stability and service life. The specific operation points are as follows:

Core Installation Requirements

Foundation Construction: The foundation for equipment installation shall be poured with concrete of C30 or above. The flatness error of the foundation shall be controlled within ≤3mm/m. At the same time, an anti-vibration cushion shall be set to reduce the impact of vibration from surrounding equipment on the shearing accuracy of the flying shear line.
Equipment Calibration: After installation, a laser collimator shall be used to calibrate the coaxiality of the conveying rollers and the shearing unit to ensure that the centerline deviation of each unit is ≤0.05mm. At the same time, the synchronization of the servo motor and the encoder shall be adjusted to ensure the speed matching during dynamic shearing.

Key Daily Maintenance Points

Tool Maintenance: Regularly check the wear of the cutting tools. When the wear amount of the tool edge exceeds 0.2mm, it shall be ground or replaced in time. After grinding, the roughness of the tool edge shall reach below Ra0.8μm to avoid burrs during shearing.
Electrical System Maintenance: Conduct dust removal and cleaning on the PLC control system and servo driver every quarter, check whether the terminal blocks are loose, and back up the control program at the same time to prevent equipment shutdown caused by program loss.
