7. Power requirements: 380V, 50Hz, 3-phase
8. Effective working speed of the whole line: 15 ~ 20m / min
2. Production process
The production line is carried out according to the following technological process:
Uncoiler → leveler → looper (material storage)→ servo feeding → multi-station punching machine (cut off)→ molding main machine → finished product discharge
3. Unit configuration and Application
3.1 Uncoiler and leveler
Uncoiler: This machine is single head mode (single support, four-bar tensioning structure, tensioning force comes from hydraulic cylinder, fast and reliable adjustment. The uncoiler is an automatic uncoiler with pneumatic pressing device. When the material coil is installed on the material shaft of the uncoiler, the material shaft of the uncoiler rotates automatically during the actual operation of the whole line, and the working speed of the uncoiler can be adjusted according to the operation of the whole line. In order to ensure the actual safety of the uncoiler, the uncoiler is equipped with pneumatic brake device.
The uncoiler also contains 4 baffles to prevent the material from loosening in the process of uncoiling.
Parameters: Allowed roll inner diameter: Ф508mm
Maximum allowable outside diameter of roll: Ф1200mm
Maximum permissible roll width: 650mm
Maximum roll bearing weight: ≤5000 kg
Leveler: Adopt 7 roller leveling, 2 pairs of feed roller, feed roller pneumatic clamping, frequency conversion speed regulation, switch control.
Parameters: Maximum working speed: 20 m / min,
Maximum leveling roll width: 600mm,
Adapt to the maximum thickness of the material coil: 1.2-3mm
Motor power of leveler: About 7.5kW (subject to final design)
Outline reference drawing of uncoiling leveling machine:
Application: Used for buffering the speed mismatch between uncoiling and punching machine and rectifying deviation; Ensure the balance between the two in the running speed, so that the whole line running smoothly, complete.3.2 Storage device
3.3 servo feeder
Application: According to the actual punching step length feeding sheet, one-time can set multiple groups of feeding parameters, convenient and fast. The feeding accuracy is accurate without cumulative error.
Parameters: maximum feeding speed: 30m / min
Maximum allowable feeding width: ≤ 650mm
Allowable feeding thickness ≤ 3mm
Feeding accuracy: ± 0.2mm/step
Brand of servo motor: Yaskawa, Japan
Servo motor power: about 4.4kw (subject to final design)
3.4 Punching machine cutting machine:
Application: it is mainly used for punching different hole types on profile.

3.5 Power transmission platform:
Application: conveying punching sheet material to molding machine
Parameters: Maximum feeding speed: 15m/min
Maximum feeding width allowed: ≤600mm
Motor power: 7.5KW
Feeding length: 16000mm
3.6 Adjustable width roll forming machine:
Purpose: it is used to reach the final cross section shape through roll bending process.
Parameters: Molding times: 16
Shaft diameter of molding machine: Φ80mm (subject to final design)
Total motor power: about 110KW (subject to final design)
Maximum linear speed: 15~20m/min
Reference drawing of the shape of the forming machine:
3.7 Hydraulic system:
Application: To provide power support for uncoiling and punching.
Motor power: about 22KW (subject to final design)
3.8 Electric control unit
The whole line adopts the man-machine control mode combined with PLC and touch screen. The specification parameters, quantity and uniform parameters can be set through the touch screen, which can store multiple sets of operation instructions at one time, with a high degree of automation. It has alarm function in case of abnormal production line, and the operation of the whole production line can be monitored through the control system. After power off or abnormal shutdown, it can continue processing according to the previous set working parameters.
Description of main electrical components:
PLC: Schneider (France)
Inverter: Schneider (France)
Touch screen: Vylon (domestic)
Low-voltage appliances: Schneider (France)
Encoder: Schneider (France)
3.9 Unpowered pallet
There are two sections in total, each section is 2m long. The material rack is a detachable structure, which is convenient for transportation and use in different sites.
