In my experience with manufacturing processes, I have gained valuable insights into the cut-to-length production line and its essential parameters. This production line is crucial for efficiently cutting materials to specific lengths, ensuring precision and quality in the final product. Understanding the various parameters that influence the performance of a cut-to-length production line has helped me optimize operations and enhance productivity. In this article, I will provide an introduction to the cut-to-length production line and discuss the key parameters that play a significant role in its efficiency and effectiveness in the manufacturing process.

Wires for processing metal materials such as silicon steel. Kaiping line, also known as Kaiping shearing line, uncoiling line, and cross-cutting line, is used to uncoil, level, cut and cut metal coils into flat sheets of required length and stack them. It is suitable for processing cold-rolled and hot-rolled carbon steel, silicon steel, tinplate, stainless steel and various metal materials after surface coating.

What is Cut-To-Length Production Line

Generally, Cut-To-Length Production Line is suitable for steel coil deep-processing enterprises, white home appliance production enterprises, etc. It is an auxiliary processing equipment for steel products. Generally, the investment is relatively large and the output is relatively balanced. A standard production line has a storage table, feeding trolley, auxiliary support, uncoiling Machine, telescopic shovel head, leveling machine, looper, side guide, five-roller rough leveling and measuring machine, shearing machine, conveyor, stacking frame, and discharging trolley. Among them, the specific configuration can be customized according to the needs of customers. Generally, it takes several months for an enterprise to produce products from customer customization to product delivery, so this is non-standard customized equipment.

Key Functions of a Cut-to-Length Production Line

1. Uncoiling – The steel coil is loaded onto a decoiler and gradually fed into the line.
2. Leveling – A precision leveler flattens the sheet to eliminate internal stresses and surface irregularities.
3. Measuring – The sheet is accurately measured by a high-precision length control system.
4. Cutting – A shear (mechanical, hydraulic, or rotary) cuts the sheet into required lengths.
5. Stacking – Finished sheets are neatly stacked for easy handling, packaging, or further processing.

Parameter

The thickness of Kaiping is different, and the configuration is different. Taking ECL-25×2300 CNC uncoiling, leveling and shearing production line as an example, the main process parameters are as follows:

Coil storage→coil trolley→uncoil→leader→finishing→transition→centering→edge trimming→transition→guiding→rough straightening→measurement→tail plate pinch→stop shearing at length→conveyor roller table→throwing machine →The blanking device is a high-performance product integrating machine, electricity and hydraulics. The entire production line can be fully automated and operated by 2-3 people.
