China Slitting Line for HR Coils - Quality Suppliers & Factory for Precision Metal Strip Production
Product Introduction
The slitting machine is a key piece of equipment in industry for cutting wide metal or non-metallic coil materials into several narrow strips of the required width along the length direction. Its core working principle is to continuously roll-cut the material through the rotation of the upper and lower circular disc knife shafts.
The following is a comprehensive introduction to the core features of the slitting and shearing machine:
Core Structure and Unit Composition
The core structure mainly consists of upper and lower knife shafts, fixed/movable frames, and a synchronous lifting mechanism. The knife shafts and frames undergo precise processing (such as turning, high-frequency treatment, grinding, and chrome plating, etc.) to ensure the rigidity and accuracy of the equipment.
Applicable Specifications & Efficiency
This series of production line is applicable to coils of various specifications. It is used for slitting the coil into required width for the use of punch line through the procedure of uncoiling, pre-leveling, cropping, slitting and recoiling. It has advantages such as proper layout, easy operation, highly automated and high production efficiency.
Material Adaptability
This line is adaptable to process cold-rolled and hot-rolled coils, silicon steel coils, stainless coils, colored coils, aluminum coils, and all sorts of plated and coated coils, and it widely applies to many industries like automobiles, containers, household appliances, food packing, construction materials, etc.
Line Integration
This line consists of loading cart, uncoiler, slitter, scrap winder, cropping shear, tension controller and coil recoiler, etc. Loop bridge, pinch and deviation corrector are equipped between each machine. This automatic coil processing line is an integration of mechanical, electrical, hydraulic and pneumatic technology.
Typical Application Industries
Widely used in various fields such as automobile manufacturing, home appliance production, construction materials (such as cabinets, kitchenware, doors and windows), hardware products, containers, electronic appliances, light industry and packaging, etc.
