The application of sheet metal machines in the field of mechanical automation has penetrated into many core links. Its technological iteration and process innovation have significantly improved the efficiency and precision of industrial production.
Automation of key processing techniques
1. Laser cutting and CNC bending
Laser cutting machines can achieve complex contour cutting of carbon steel, aluminum alloys and other materials through high-precision programming, while CNC bending machines combined with robot automatic following technology can complete multi-angle bending operations with accuracy errors controlled within ±0.1mm. For example, the elevator door panel bending production line realizes unmanned operation through the servo positioning system.
2. Stamping and welding
The automated stamping unit adopts a PLC control system and cooperates with the visual inspection module to realize the integrated operation of punching and pressing, and the waste collection efficiency is increased by 40%. In the welding process, laser welding is commonly used to replace traditional spot welding to reduce thermal deformation and improve structural strength.
Industry-level application scenarios
1. Automotive and Aerospace
Sheet metal parts are used for body structures, engine hoods and other components, and multiple models can be produced on the same line through flexible production lines.
2. Electronics and medical devices
High-precision cabinets and surgical instrument casings rely on automated sheet metal processing. For example, medical equipment casings use rivet-free connection technology to avoid chemical contamination.
3. Elevators and electrical equipment
The automated elevator hall door panel production line integrates stamping, bending, and riveting processes, and uses a visual positioning system to shorten the production cycle to 30% of the traditional model.
Construction of intelligent production system
1. Automated logistics system
● The three-dimensional material warehouse cooperates with the robot to realize automatic storage and retrieval of plates. For example, the 8-meter heavy-duty three-dimensional material warehouse cooperates with AGV transportation, and the space utilization rate increases by 60%.
2. Digital twins and process optimization
● The digital sheet metal production system optimizes stamping parameters through simulation, increasing the material utilization rate from 65% to 85%.
3. Quality monitoring closed loop
● The online detection module monitors bending angle, welding penetration and other parameters in real time, and abnormal data automatically triggers process adjustments.
Economic benefits and technical advantages
1. Reduce costs and increase efficiency
● After reducing manual intervention in the bending robot workstation, the number of single-line operators was reduced from 5 to 1, and the overall cost was reduced by 35%.
2. Flexible production adaptability
● The bending robot supports rapid mold change, and the switching time for small batch orders is reduced from 2 hours to 15 minutes.
3. Environmental protection and sustainability
●The laser cutting process reduces mold consumption, the scrap rate is reduced from 12% to less than 5%, and green manufacturing is achieved with recyclable materials.
Future trends
1. Smart factory: 5G+industrial Internet realizes full life cycle management of equipment, and predictive maintenance reduces the risk of downtime.
2. Human-machine collaboration upgrade: dual-arm robots will be expanded to complex curved surface sheet metal repair scenarios
