Slitting machine introduction

Slitting machine, also known as slitting line, slitting machine, slitting machine, is a name for metal slitting equipment.

1. Purpose: Suitable for longitudinal shearing of metal strips, and rewinding the slit narrow strips into rolls.

2. Advantages: easy operation, high cutting quality, high material utilization, stepless speed regulation of cutting speed, etc.

3. Structure: It consists of unwinding (unwinding), material positioning, slitting longitudinal cutting, winding (rewinding), etc.

4. Applicable materials: tinplate, silicon steel sheet, aluminum strip, copper, stainless steel plate, galvanized plate, etc.

5. Applicable industries: transformers, motors, home appliances, automobiles, building materials, packaging industry, etc.

The main components of the hydraulic system of this production line use high-precision components, and the electrical control uses imported PLC program controller and touch screen for full-line function control. It has the characteristics of high degree of automation, good leveling quality, high shearing accuracy, stable and reliable performance, and convenient operation and maintenance. The coil can be loaded once to achieve the smooth completion of each process, effectively reducing the labor intensity of workers. It has a high cost performance and is a high-performance product integrating machinery, electricity and hydraulics.

◆ Using finite element analysis method, after computer-aided optimization design, the product design structure is reasonable;

◆ The overall steel plate welding structure of the machine body, Aging heat treatment is used to eliminate the internal stress of the frame, with good strength, rigidity and vibration resistance, and the product has a long service life;

◆ The manufacturing process of the whole machine is strictly produced in accordance with the design specifications of the machine. The body is formed in one go by a CNC floor-standing boring and milling machine to ensure the parallelism and verticality of each installation surface;

◆ The material is selected according to experience, the processing technology is complete and reasonable, and the product accuracy and accuracy retention are effectively improved;

◆ The main purchased accessories are well-known domestic and foreign brands to ensure stable product performance;

◆ The degree of automation is high, the operation is convenient and simple, and the gap between the upper and lower working rollers can be quickly adjusted by the motor, which effectively shortens the auxiliary time and has high efficiency;

◆ The motor control system basically adopts weak current control, and its operator only needs to operate through the human-machine interface and the button station to ensure the safety of the operator;

◆ The overall frame is rust-proof and sprayed with anti-rust paint, and the appearance color is long-lasting and bright;

◆ The working shaft support of the whole machine adopts heavy-duty bearings, combined with advanced lubrication system, and has a long service life
