Automotive Backlite & Sidelite Glass Tempering Furnace

1. Machine Application

LV-TB1508L-08V-III Double & Single Curvature Bent Glass Tempering Machine is a special plant used to produce the bent tempered glass with double curvature and single curvature, which mainly used in the fields of rear doors and side doors of automotives, trucks, furniture, etc. Our customer produced the rear doors and side doors for BMW, Audi, Toyota, Honda, Hyundai, Peugeot, etc.

2. Supply Scope:

2.1. Loading table

2.2. Bending section (08L) for side doors

2.3 Heating section

2.4. Forming section with mould(s) for rear doors (08V)

2.5. Quenching section for rear doors

2.6. Transmission section for rear doors

2.7. Cooling section for rear doors

2.8. Unloading table

2.9. Blower system

2.10. Electrical & control system

2.11. Emergency power system (EPS) for emergency driving system

2.12. Emergency cooling system

2.13. Glass mould (1 set)

2.14. Spare parts as listed in appendix

2.15. Technical documents

3. Machine Main Features:

3.1. In the bending forming, for transmission of pressing mould, support mould and rollers, we use servo motors & servo controllers

3.2. In quenching section, for transmission of mould carrier, we use servo motors & servo controllers.

3.3. Equipped with heating & insulating system in forming section, which could keep temperature of the forming section so that the glass is formed in high temperature.

3.4. Easy-making and cheap moulds

3.5. Easy & quick moulds changing-time

3.6. Smaller roller distance in heating oven which guarantee the high quality

3.7. Heating section has a helix matrix structure, which can control the temperature of each area independently. Reasonable design and unique structure of heating elements make a long serve life.

3.8. The heating oven body is full closed and the Insulating materials are of high quality material with top performance which can ensure very lower energy consumption.

3.9. Ceramic rollers are the top quality products.

3.10. Ceramic roller driving adopts seamless round belts.

3.11. Fault diagnosis system for the heating elements.

3.12. Remote diagnosis function

3.13. We use only two connecting communication between the thermocouples and computer, which will avoid the interruption and make the temperature-mearsuring more exact.

3.14. The working condition of every thermocouple could be monitored automatically, and the warning will come out if there is any abnormal situation.

3.15. Adopting PID for temperature control, which has the better anti-interference function and higher temperature-control precision.

3.16. Equal three phase power consumption during automatic heating up period; avoiding phase no-equal during no-heating period automatically.

3.17. The fine-adjustment for oven temperature could be achieved by fine-adjusting the temperature of every heating element.

3.18. During the night, the furnace can stay at sleep mode around 500-550 degrees celcius and preheating takes place before the start of the shift in the morning so that the furnace is ready for production

3.19. The production process, temperature, time, air pressure, etc could be recorded. Therefore, testing production could be saved and production stability could be improved. Also, the production state in different batches could be tracked.

3.20. The machine has the history record and printing function. When glass come out from the oven, the computer will record the control parameters automatically for reference in future or pint them out.

3.21. Powerful operation prompt facility; if there is any wrong operation or fault, the dialog box will be called out to give you help.  

3.22. Preventive function for the wrong operation. The data which affects the system running has been restricted strictly. The different operator has the different access right to system setting.

3.23. Power monitoring function, the monitoring program could monitor most of the sensors.

3.24. An emergency power system is provided for the driving system to ensure safety of ceramic rollers inside the furnace when there is a sudden power off.
