longitudinal slitting machine
A longitudinal slitting machine is a kind of equipment that cuts and strips metal plates or coils, etc. along the longitudinal direction.
High processing accuracy
Precise dimensions: The longitudinal slitting machine adopts advanced cutting technology and a high-precision transmission system, which can accurately control the cutting width and dimensions. For example, in the automotive manufacturing industry, there is a high requirement for the width accuracy of body panels. The longitudinal slitting machine can cut the panels into precise dimensions with an error within ±0.1mm, ensuring the precise assembly of body components.
Smooth cut edges: Through optimizing the tool design and cutting process, the longitudinal slitting machine can make the edges of the cut panels smooth and burr-free, and both the perpendicularity and flatness of the cut edges can reach high standards. In the manufacturing of electronic devices, such smooth cut edges can avoid damage to electronic components and improve the quality and reliability of products.
High production efficiency
High-speed cutting: The cutting speed of the longitudinal slitting machine is usually very fast. Some advanced equipment can cut tens of meters or even hundreds of meters of panels per minute. In the steel processing field, the high-speed longitudinal slitting machine can greatly shorten the production cycle and improve the production efficiency and market competitiveness of enterprises.
Continuous operation: It is equipped with an automated feeding, cutting, and unloading system, which can achieve 24-hour uninterrupted continuous operation. Taking the longitudinal slitting of metal coils as an example, the equipment can complete the continuous cutting and slitting of the coils without stopping the machine, reducing manual intervention and downtime, and further improving production efficiency.
Strong processing flexibility
Can cut a variety of materials: It can cut panels of different materials, such as stainless steel, carbon steel, aluminum alloy, copper alloy, etc. In the aerospace field, it can perform longitudinal slitting processing on high-strength aluminum alloy panels to meet the needs of aircraft structural component manufacturing; in the power industry, it can also cut materials such as copper busbars for the production of electrical equipment.
Adjustable cutting width: It can easily adjust the cutting width according to the different needs of users. In the architectural decoration industry, according to different decoration requirements, the longitudinal slitting machine can cut panels into strips of various widths, which are used for making door and window frames, decorative lines, etc.
High degree of automation
Simple operation: It is equipped with an advanced numerical control system. Operators only need to input relevant parameters such as cutting width, length, and speed on the control panel, and the equipment can automatically complete the cutting task. This reduces the skill requirements for operators and minimizes the impact of human factors on processing quality.
Fault diagnosis and early warning: It has an automatic detection and fault diagnosis function, which can monitor the running status of the equipment in real time. When a fault occurs, the system will immediately issue an alarm and display the fault code and location, facilitating maintenance personnel to quickly troubleshoot and repair. At the same time, it can also predict the service life of key components of the equipment and provide maintenance reminders, preventing faults in advance and ensuring the stable operation of the equipment.
Energy-saving and environmentally friendly
Energy-saving design: By adopting high-efficiency motors and transmission systems, while ensuring the cutting power, it reduces energy consumption. Compared with traditional cutting equipment, the energy consumption of the new type of longitudinal slitting machine can be reduced by 20% - 30%, effectively saving production costs.
Waste recycling and utilization: During the cutting process, less waste is generated, and the size of the waste is relatively regular, making it easy to recycle and utilize. Some longitudinal slitting machines are also equipped with waste collection and compression devices to compress and pack the waste, making it convenient for transportation and reprocessing, reducing resource waste and the impact on theenvironment.
The steel longitudinal slitting machine includes one or more sets of rotating cutter wheels, which cut along the length direction of the steel plate. When the machine is in operation, the cutter wheels rotate at a high speed. After the steel coil is uncoiled by the uncoiler, it is transported to the position of the cutter wheels of the longitudinal slitting machine. The cutter wheels precisely cut the steel according to the predetermined width, and cut the wide steel coil into multiple metal strips with the same width. Different steel longitudinal slitting machines vary in tool configuration and cutting methods. For example, in the active shearing form, the motor-driven pinch rolls ensure that the steel enters the shear guiding device in the center; in the passive shearing form, the coiler actively pulls the uncoiler and the disc shears to rotate together.
Cutter Shaft and Tools: The cutter shaft is usually made of high-strength alloy steel, which has good rigidity and wear resistance and can withstand the huge pressure and torque during cutting. The tools are generally made of high-quality cemented carbide or high-speed steel, with sharp cutting edges and strong wear resistance, which can ensure the cutting quality and the service life of the tools. The cutter shaft is equipped with multiple cutter discs and a series of spacers with different thicknesses. By adjusting the arrangement of the cutter discs and spacers as well as the spacing between the cutter shafts, the cutting width and the overlap amount of the cutter blades can be changed.
Transmission System: Generally composed of motors, reducers, gearboxes, universal joints, etc., it transmits the power of the motor to the cutter shaft, enabling the cutter shaft to rotate at a stable speed. The transmission system requires high transmission precision and large torque to ensure the stability of the tools during the cutting process and the cutting precision.
Hydraulic System: It is used to control the tension of the uncoiler, the pressure of the pinch rolls, the adjustment of the cutter shaft, and the expansion and contraction of the coiler and other actions. The hydraulic system has the characteristics of fast response speed and precise pressure control, and can provide reliable power support for the stable operation of the equipment.
Electrical Control System: It adopts an advanced PLC (Programmable Logic Controller) and a touch screen human-machine interface, which can realize the automatic control of the equipment. The operator inputs parameters such as cutting width, length, and speed through the touch screen. The PLC controls the operation of each component according to the set parameters. At the same time, it can also realize functions such as fault diagnosis and alarm, which is convenient for the operation and maintenance of the equipment.
Steel Processing Industry: It is used to slit hot-rolled or cold-rolled steel coils into narrow strips of different widths, providing blanks for subsequent deep processing processes such as stamping, cold rolling, and welding.
Automobile Manufacturing Industry: It provides steel strips of various widths for the manufacturing of automobile body, frame, chassis and other components, ensuring the strength and precision of automobile parts.
Home Appliance Industry: It provides steel strips of appropriate widths for the shells, brackets and other components of home appliances, meeting the appearance and structural requirements of home appliances.
Construction Industry: It can process steel strips used in building decoration, steel structure manufacturing, etc., such as building door and window frames, roof panels, keels, etc.
Electronics Industry: It provides high-precision steel strips for the shells, radiators and other components of electronic devices.
