Production process:
The production line is operated according to the following process flow: Uncoiling → Loop (storage) → Servo leveling feeding → 315T punching (cutting) + punching and strengthening press → cold bending → discharging
Roll Forming Machine - 1 set
Purpose: Used to achieve the required interface shape through the roll bending process.
Structure: The forming unit adopts an independent frame (quick-change arch style). Driven by motor and reducer, and driven by a reduction box. The forming roller is designed by professional software. The material is made of high-quality mold steel Cr12, with a hardness of HRC58~62 after quenching (physical characteristics are equivalent to American material D2). The roller surface is polished after fine machining. The roller has high precision and long life.
The lower shaft is driven, and the upper and lower shafts use synchronous gears if necessary. The main drive is driven by a reduction box. The object material of the reduction box is ZG45 or steel plate welding.
The outer nut of the arch is left-handed (lower shaft) and right-handed (upper shaft).

Hydraulic system -2 sets
Purpose: 1 set provides power for the unwinder, loading trolley and punching machine; the other set provides power support for hydraulic cutting.
Structure: The pump and accumulator combination structure is adopted, and the punching and shearing action speed is fast, which improves the production line speed. The air-cooled cooler is used for heat dissipation to meet the production requirements of high load and high temperature. This hydraulic system is a fast hydraulic system, suitable for high-speed punching, hole roller and shearing cold bending production lines. The main hydraulic components are Beijing Huade products.
The main components are: oil pump, motor, hydraulic valve, solenoid valve, filter and hydraulic oil tank, etc.
The hydraulic system uses a filter, and the cleanliness of the oil is guaranteed to be 6-8 levels.
Electrical control unit -1 set
The whole line adopts a human-machine control mode combining PLC and touch screen. The specifications, quantity and system parameters of the parts can be set through the touch screen. Multiple sets of operation instructions can be stored at one time. It has a high degree of automation and has an alarm function in the event of an abnormality in the production line. The operation of the entire production line can be monitored through the control system. After power failure or shutdown in an abnormal state, processing can continue according to the previously set working parameters.
