Straightening Machine for Titanium/Steel/Metal Bar/Pipe
Rotating Anti-Bending and Straightening Machine
Multiple Rolls Straightening Machine
This device is a vertical straightening processing line equipped with multiple skew rolls. Obviously, it can resolve head-tail bends, eliminate slight ovality and remove oxidized iron surface sheet.
Main Characteristics: --Adopt optimized quasi-double curve and deep/shallow concave shape complex rolling system (evolved from convex and concave roll), the straightening precision is higher. --Adopt the principle of double rolls pressing with controllable load and flexible frame, thus expand the scope of bar plastic area, which can improve the straightening precision and protect mechanical equipments from damages. --Main transmission adopts SIEMENS's full -digital DC (or AC VFD) gear, stepless speed, constant torque output under basic speed and constant power output above basic speed. Besides, it adopts self-adaptive (AGC) control system, for two motors, the speed is balanced under no-load status, thus makes the motor performance to be fully reflected. --The programme control adopts the PLC system, and uses PROBIBUS-DP field bus for communications, which forms an integrated automatic network together with remote I/O on operating platform and human-computer interface. According to HMI, it is suitable for process requirements. From front-desk feeding, adjustment of the parameters of straightening machine (including automatic regulation of straightening rolls and angles), to back-desk unloading, it can achieve full-course automatic, manual and semi-automatic controls, and it is equipped with sound/light alarming system for fault detectors. --The hydraulic system adopts constant-pressure pump as power source and accumulator's quick supplement of oil. The overload unloading adopts direct-acting overflow valve, which may maintain the pressure and buffer, and also provide assurance to protect mechanical equipments and enhance finished product rate. --The loading and unloading system has a variety of options for users, so as to meet the requirements better.
