Horizontal cutting line

In terms of processing precision:
High fixed-length precision: It can accurately cut the steel plate transversely into the required length according to the preset size. For example, the cutting piece error of the HL-HJD series of silicon steel sheet transverse cutting line can be controlled within ±0.2mm.
High flatness of the sheet material: Through devices such as a leveling machine, the uncoiled steel plate is leveled to eliminate the deformation generated during the rolling, transportation and other processes of the steel plate, so that the final flatness of the sheet material is high, which can meet the application scenarios with high requirements for the flatness of the sheet material, such as automobile manufacturing, precision instrument manufacturing, etc.
Accurate angle precision: During the cutting process, the accuracy of the cutting angle can be ensured. For example, the cutting piece angle error of the HL-HJD series of silicon steel sheet transverse cutting line can be controlled within ±0.025°.

In terms of production efficiency:
High-speed cutting: It has a high cutting speed and can achieve rapid cutting operation of the steel plate. Some high-speed transverse cutting lines can cut dozens of times or even more per minute, greatly improving the production efficiency and meeting the needs of large-scale production.
Continuous operation: A series of processes from uncoiling, leveling to cutting and stacking can be carried out continuously and automatically, reducing manual intervention and the waiting time between processes, and improving the overall production efficiency.
Automatic tool change: Some advanced steel plate transverse cutting lines are equipped with an automatic tool change function. When the tool is worn to a certain extent, it can automatically change the tool without stopping the machine for manual tool change, further improving the production efficiency.

In terms of product quality:
Good burr control: By adopting advanced cutting technology and tools, the burrs generated during the cutting process can be effectively controlled. For example, the cutting burrs within the service life of the HL-HJD series of silicon steel sheet transverse cutting line are ≤0.02mm.
Excellent cutting quality: During the cutting process, the force between the tool and the steel plate is uniform, which can ensure that the cutting edge is neat and free of defects such as tearing and deformation, improving the cutting quality of the steel plate.
High surface quality: During the whole processing process, the surface of the steel plate is well protected, and defects such as scratches and indentations on the surface of the steel plate caused by equipment reasons will not occur, which can well maintain the original surface quality of the steel plate.

In terms of operation and maintenance:
High degree of automation: By adopting advanced control systems such as PLC controllers, one-key production can be realized. Only one person is needed to operate the whole set of equipment, reducing the demand for labor and lowering labor costs.
Fault diagnosis and early warning: Equipped with a fault diagnosis system, it can monitor the running status of the equipment in real time. Once a fault is found, it can quickly locate the fault point and send out an alarm signal in time, which is convenient for maintenance personnel to carry out maintenance.
Low maintenance cost: The key components are made of high-quality materials and advanced manufacturing processes, which have high wear resistance and reliability, reducing the number of equipment repairs and the replacement frequency of parts.

In terms of safety performance:
Overload protection: The hydraulic transmission type transverse cutting line can automatically prevent overload, and the work is safe and reliable.
Protective devices: Equipped with complete safety protection devices, such as protective covers, safety light curtains, emergency stop buttons, etc. The protective cover can isolate the dangerous parts of the equipment from the operators to prevent personnel from contacting the moving parts and tools; the safety light curtain can immediately stop the operation of the equipment when someone or an object enters the dangerous area.
Stable structure: The body is welded with high-quality steel, and the structure is firm and stable. Heat treatment eliminates the hidden danger of deformation, which can ensure the stability and safety of the equipment under high-speed and high-load operating conditions.
