3. Combine machine: Separate unit flattener and punching( two in one )with Servo feeding motor

3.1. Separate unit flattener:
3.1.1. With the sense press (start-stop)
3.1.2. Weight: 5000Kg
3.1.3. Structure features: quenched and tempered leveling rollers, chrome plated treatment the rigidity, surface roughness and other mechanical properties is greatly increased; Its consist of feeding rollers and leveling rollers. The feeding rollers can be adjusted separately. Leveling roller adopts integral structure, there are two adjustment device at previous and behind. It can form angle of inclination to improve the quality of leveling device. At the feeding side, there is a pair of guiding rollers and two pairs of vertical rollers. Leveling machine has leading material device at previous and behind. There is photoelectric signal between Leveling machine and feeding device, and then feedback into PLC control panel, PLC releases instructions to frequency conversion motor speed to control the storage of the raw materials in the loading zone, leveling continually.
3.1.4 .The guiding rollers move simultaneously with the forming part by PLC. The thickness of leveling part levels up by press button. There is two digital monitor between the guiding rollers.
3.1.5 .It will add one roller to press the material before running into flattener device with button.
