Metal cut to length machine is a kind of production equipment specially used for automatic decoiler, leveling, shearing and stacking of metal coils, which is used to process metal coils into plates or sheets of required size. It is an important part of modern metal processing, with the characteristics of high efficiency, high precision and high degree of automation, and is widely used in many industries, such as automobile manufacturing, home appliance production, architectural decoration and aerospace.

1. Loading and unwinding

- The metal coil is placed on the unwinding machine by a forklift or a crane, and the metal coil is gradually unwound by the decoiler.

- Equipped with automatic centering device to ensure that the unwinding process of the coil is smooth and does not deviate.

2. Leveling correction

- The unwound metal coil enters the leveling machine, and the leveling roller eliminates the defects of the coil such as waves and warping.

- The leveling process ensures that the surface of the metal sheet is smooth and flat, providing quality assurance for subsequent shearing and application.

3. Shearing

- The flattened metal sheet enters the shearing device and is sheared to a fixed length according to the set size.

- The shearing types are usually divided into mechanical shearing and hydraulic shearing to meet different sheet thickness and shearing accuracy requirements.

4. Stacking

- The sheared metal sheet is sent to the stacking area through the conveyor device and automatically stacked neatly.

- equipped with automatic flip or suction cup manipulator device, the stacking efficiency can be further improved.

5. Waste treatment

- The shearing line is also equipped with a waste treatment system to collect the scraps generated during the shearing process for easy recycling or treatment.

1. Decoiler: Unroll the metal coil with support and positioning functions.

2. Leveler: Correct the flatness of the coil surface to ensure shearing accuracy.

3. Shearing device: Precisely shear the sheet according to the required length.

4. Conveying system: Transfer the metal sheet between each process to ensure production continuity.

5. Stacker: Automatically stack the cut sheets for easy transportation and storage.

6. Control system: PLC or touch screen system to achieve parameter setting, automatic operation and real-time monitoring.

1. Automobile manufacturing

- Used to produce key components such as body sheets and chassis sheets to improve assembly accuracy and material utilization.

2. Home appliance industry

- Manufacture metal parts such as refrigerator shells and washing machine panels to ensure dimensional accuracy and surface finish.

3. Building decoration

- Process curtain wall sheets, roof materials and metal decorative panels to meet the diverse needs of the construction field.

4. Aerospace

- Provide high-precision metal sheets for aircraft fuselages and aviation parts.

5. Metal processing

- Provide metal sheets of the required size for subsequent processes such as stamping and bending.

1. High efficiency

- The cut to length line realizes continuous production and greatly improves the efficiency of metal sheet processing.

2. High precision

- Equipped with advanced leveling and shearing equipment, it can ensure the minimum dimensional error of the finished product.

3. High degree of automation

- Through PLC or industrial computer control, multi-process linkage and unmanned operation are realized to reduce manual intervention.

4. Cost saving

- By optimizing the shearing process and waste handling system, material waste is reduced and material utilization is improved.

5. Diversified adaptability

- The cut to length line can be customized according to the thickness, material and length requirements of the plate to meet the needs of different industries.

The metal cut to length machine is an efficient metal sheet processing equipment. Its core process is to shear metal coils into plates according to predetermined sizes. The shearing type directly affects the efficiency, shearing accuracy and material utilization of the production line. According to different production requirements and equipment structures, the shearing types of metal shearing lines are mainly divided into fixed shearing, swing shearing and flying shearing. The following is a detailed introduction to these three shearing types and their characteristics.

 1. Fixed station shearing

Definition and principle

Fixed shearing is the most basic shearing method, also known as fixed shearing or intermittent shearing. It uses a fixed-length conveyor for metal materials. After the plate stops moving, the shearing operation is completed by a shearing device at a fixed position. After the shearing is completed, the material moves forward to the set length again and repeats the process.

Features and advantages

- High precision: Fixed shearing uses static shearing to ensure accurate shearing dimensions.

- Wide applicability: Suitable for shearing metal plates with larger thicknesses, such as steel plates, stainless steel plates, etc.

- Simple equipment: The structure is relatively simple and easy to maintain.

Application scenarios

- Used for shearing of medium and thick plates with high precision requirements, such as steel plates for construction, automobile chassis plates, etc.

Limitations

- Low shearing efficiency, not suitable for mass production.

- Material delivery needs to be stopped for each shearing, which affects the continuous production rhythm.

 2. Swing shearing

Definition and principle

Swing shear is a way of cutting by swinging the shearing tool holder. The shearing tool holder swings around a fixed point to achieve shearing of metal materials. This method is usually used in continuous production lines, and the material delivery speed is relatively slow.

Features and advantages

- High efficiency: Compared with fixed shearing, swing shearing is suitable for medium-speed production lines and has higher production efficiency.

- Smooth shearing: The swing design of the tool holder can effectively reduce vibration during shearing and improve the surface quality of shearing.

- Moderate cost: The equipment complexity is moderate, and the investment and maintenance costs are suitable for most companies.

Application scenarios

- Used for medium-speed shearing of medium and thick plates, such as metal shell plates in the home appliance industry.

Limitations

- Limited scope of application, not suitable for extremely high-speed production.

- The shearing accuracy of thin plate materials may be slightly inferior to fixed shearing.

 3. Fly Shearing

Definition and principle

Flying shear is a dynamic shearing method that completes shearing while the material is continuously transported. The shearing device keeps synchronous movement with the material during the shearing process, and returns to the initial position after shearing to prepare for the next shearing.

Features and advantages

- Ultra-high efficiency: Flying shear can match high-speed production lines, greatly improving production efficiency.

- Continuous production: No need to interrupt material transportation, suitable for long-term continuous processing.

- Strong flexibility: Suitable for shearing of metal coils of various materials and thicknesses.

Application scenarios

- Used for large-scale, high-speed shearing production, such as metal sheet production in automobile manufacturing.

Limitations

- The equipment structure is complex and requires high operation and maintenance technology.

- The initial investment is large, only suitable for enterprises with high production capacity requirements.
