In terms of production efficiency

High - speed shearing: The steel plate flying shear and finishing shear line equipment can perform shearing operations while the steel plate is moving at a high speed, greatly shortening the single shearing cycle. Compared with traditional static shearing equipment, the production efficiency is significantly improved. For example, in some large - scale steel processing enterprises, using the flying shear and finishing shear line equipment can increase the shearing speed of steel plates by several times or even dozens of times, enabling the rapid completion of a large number of steel plate shearing tasks.
Continuous operation: This equipment can achieve continuous and uninterrupted shearing operations. From the loading, conveying, shearing to unloading of steel plates, the entire process can be carried out automatically and continuously. It reduces the time loss caused by equipment start - stop and manual intervention, improves the overall operating efficiency of the production line, and can effectively meet the needs of large - scale production.

In terms of shearing accuracy

Accurate fixed - length shearing: The steel plate flying shear and finishing shear line equipment is equipped with a high - precision measurement and control system, which can accurately shear the steel plate according to the preset length. The shearing accuracy can be controlled within a very small error range, generally reaching an accuracy of ±1mm or even higher, effectively ensuring the consistency and accuracy of product dimensions.
Good cutting quality: Through the optimized shearing process and tool design, the flying shear and finishing shear line equipment can make the cut of the steel plate flat and smooth during the shearing process, without obvious defects such as burrs, tears or deformation, improving the shearing quality of the steel plate and facilitating subsequent processing and use.

In terms of operational flexibility

Adjustable parameters: Parameters such as the shearing speed, shearing length, and shearing angle of this equipment can be flexibly adjusted according to different production needs. Operators can easily set and modify these parameters through the equipment's control system to meet the shearing requirements of steel plates of different specifications and materials, showing strong universality and adaptability.
High degree of automation: The steel plate flying shear and finishing shear line equipment usually adopts an advanced automatic control system, with functions such as automatic loading, conveying, shearing, and unloading. It can also be seamlessly connected with other production equipment to realize the automatic operation of the entire production process, reducing the workload and labor intensity of manual operation, and at the same time improving the safety and stability of production.

In terms of material utilization

Optimized shearing algorithm: The flying shear and finishing shear line equipment uses an advanced optimized shearing algorithm, which can reasonably plan the shearing scheme according to the original size of the steel plate and customer needs, minimize the generation of scrap materials, improve the material utilization rate, and reduce production costs.
Recycling of remaining materials: During the shearing process, the equipment can automatically collect and classify the remaining scrap materials and remnants, facilitating subsequent recycling, further improving the resource utilization efficiency, and meeting the requirements of green production and sustainable development.

In terms of equipment maintenance

Compact structure: The overall structure of the steel plate flying shear and finishing shear line equipment is relatively compact, and the layout of each component is reasonable, which facilitates the installation, debugging, maintenance, and upkeep of the equipment. At the same time, the key components of the equipment are manufactured using advanced processes and high - quality materials, with high wear resistance and reliability, reducing the equipment failure rate and maintenance costs.
Fault diagnosis system: This equipment is equipped with a complete fault diagnosis system, which can monitor the operating status of the equipment in real - time. Once a fault or abnormal situation is detected, the system will immediately issue an alarm signal and accurately locate the fault position, providing timely and effective maintenance guidance for maintenance personnel, shortening the equipment maintenance time, and improving the equipment utilization rate.

Product Details

Structural Composition
Uncoiler: It is used to support the steel coil and achieve the uncoiling function. It actively uncoils during the initial threading process and passively uncoils during normal operation. Generally, it is composed of a drum, a machine base, and a transmission system, and is often equipped with a hydraulic auxiliary support and a strip end pressing device.
Leveler: It is mainly composed of a motor, a speed reducer, a power take-off box, upper and lower roll seats, leveling rolls, a lifting mechanism, a lubrication part, a frame, and a base, etc. It can level the steel plate, eliminate the stress of the strip, and make the stress distribution uniform.
Feeding Mechanism: It usually includes conveying roller tables, pinch rolls, etc., and is responsible for smoothly and accurately conveying the leveled steel plate to the position of the flying shear, ensuring that the conveying speed and accuracy of the steel plate match the shearing rhythm of the flying shear.
Flying Shear Plate Shearing Machine: It is the core component, generally composed of a movable tool holder, a gearbox, a servo power supply device, a crankshaft, etc., and drives the blade to perform rotary cutting through a double crank. It is also equipped with a shear blade clearance adjustment mechanism, etc., to ensure the shearing quality of plates with different thicknesses.
Conveying Device: It is composed of conveying roller tables, belt conveyors, etc., and conveys the sheared steel plate to the stacking device or the next process. Some also have functions such as turning and diverting the steel plate.
Stacking Device: It is equipped with a supporting robotic arm, a single-sided striking plate, a tail striking plate, etc. Through the cooperation of air pressure and hydraulic pressure, it neatly collects the sheared steel plates, reduces the damage to the plate surface, and then transports them out through the discharge roller way.
Auxiliary Systems
Hydraulic System: It provides power for the hydraulic auxiliary support of the uncoiler, the shearing action of the flying shear, the lifting of the stacking device, etc.
Pneumatic System: It is used to control some components that require rapid response and flexible operation, such as the pneumatic discharge rack and the pneumatic pinch rolls.
Electrical Control System: It adopts advanced controllers and programming software to achieve the automatic control of the entire production line, coordinate the actions of each component, and ensure the stability and high efficiency of the production process.
Working Principle
Speed Matching Principle: The horizontal speed of the shear blade of the flying shear must be equal to or slightly greater than the movement speed of the steel plate to ensure that the shear blade can smoothly cut into the steel plate during shearing and will not cause pulling or deformation to the steel plate.
Synchronous Control Principle: Through the control system, the operation time and speed of each component are precisely controlled, so that all links such as uncoiling, leveling, feeding, shearing, conveying, and stacking are closely coordinated to achieve continuous and stable production.
Positioning Control Principle: Detection devices such as encoders and sensors are used to monitor the position and movement state of the steel plate in real time, and the signals are fed back to the control system. The control system precisely controls the shearing timing of the flying shear according to the preset fixed length and shearing position to ensure the shearing accuracy.
