Introduction of characteristics

(1) The upper roller main shaft and the lower middle roller main shaft can be separated from the mold, and the roller main shaft and the mold on both sides are integrally forged, and the material thereof is GCr15.
(2) All rotating surfaces of the machine tool are rolling contact (original imported German FAG) and automatic lubrication at regular intervals. It is forbidden to use copper sleeve.
(3) All sliding surfaces of the machine tool are inlaid with graphite aluminum bronze (QAIG-A) and automatically lubricated at regular intervals.
(4) The machine bed is heated and welded with Q345 or 16Mn. The design of the ribs is criss-crossed and heat-treated to eliminate internal stress and prevent permanent deformation.
(5) The main shaft and other parts are made of alloy steel and tempered or quenched.
(6) The rectangular sliders on both sides of the lower roller are designed as the square cylinders of the displacement cylinders on the two sides of the lower three rollers. The cylinder is the lower displacement slider, and the overall structure is compact, which greatly reduces the number of parts and is extremely stable and durable. (Utility model patents)
(7) Germany Siemens (SIEMENS) PLC program control system + color human-machine interface (touch screen) allows the operator to observe the roll forming process at a glance.
(8) Italy BLM electro-hydraulic servo hydraulic integrated system + Germany Siemens (SIEMENS) PLC + Germany HEIDENHAIN (HEIDENHAIN) grating ruler (positioning accuracy ± 0.1mm) control the displacement of the cylinder on both sides of the lower roller, achieving high positioning accuracy and high displacement accuracy of the machine tool Closed loop control.
(9) One end of the upper roller contains a guide device that can be tipped over to facilitate the unloading of the entire round workpiece.
(10) The hydraulic oil tank is equipped with a heating and condensing system (condensing machine), so that the oil temperature in the fuel tank is maintained at a stable temperature of 45-50 degrees required by the hydraulic system throughout the 16 hours of daily working hours.

The upper roller main shaft and the lower middle roller

The upper roller main shaft and the lower middle roller main shaft can be separated from the mold, and the roller main shaft and the mold on both sides are integrally forged, and the material thereof is GCr15.

Servo oil pump motor unit

The upper roller shaft is fixed, and the lower three roller displacement is realized by the Siemens SIEMENS PLC+2 servo oil pump motor units (Italian BLM electro-hydraulic servo system), the displacement cylinder stroke on both sides of the three rollers is realized, and the high precision of the two rollers The displacement and high-precision positioning are closed-loop control by the German HEIDENHAIN grating (non-wire encoder), which results in extremely stable curvature (scale detection accuracy of ±0.1).

Pre-bending ability

Under the guaranteed strength, the shorter the distance between the four rollers, the better (there is only a planetary reduction mechanism in the world to obtain a larger transmission torque at the same diameter), in order to obtain the arc-shaped wave plate “zero straight line segment” (Note: the actual situation There will always be a straight line segment), and the lower rollers on both sides must have sufficient displacement force to achieve pre-bending.

Imported hydraulic valve level

The upper roller and the middle lower roller are active rotary rollers, which are directly driven by the variable frequency motor + planetary reducer (no motor leakage, hydraulic valve jam phenomenon) and digitally controlled by the PLC+ inverter. More precise fine-tuning of two independent drive roller speeds is required to achieve a uniform and efficient turning force.

Overturning

One end of the upper roller contains a guide device that can be tipped over to facilitate the unloading of the entire round workpiece.
