Xian SanMore Machinery & Equipment Co., Ltd.

We are offering two roll straightening machine. this device is a two-roll vertical straightening machine, mainly comprised of straightening machine and feeder system, and equipped with the corresponding electric control, hydraulic, pneumatic and lubricative devices. It is mainly used to precisely straighten and tumble alloy bars after peeling, with high straightening precision and good surface roughness, so it is the indispensable device for production of bright materials.rnmain characteristics:rn1. Adopt convex-concave roll, and the rolling curve is comprised of straightening, tumbling and transition sections, with both straightening and tumbling roles. As a line-contact device, it can achieve full-range straightening and tumbling.rn2. Adopt double rolls pressing/straightening principle with constant-pressure load control, turn rigid frame into flexible one, and ensure required pressure on straightening and tumbling of bars. Whats more, it can reduce head-tail necking phenomenon and protect mechanical equipments.rn3. Adopt electric adjustment and digital display for roll clearance, characterized by high sensitivity and reliability, and convenient operation and maintenance.rn4. The hydraulic system, equipped with hydraulic station, adopts ram pump as power source. The overload unloading adopts direct-acting overflow valve, which may maintain the pressure and buffer.rn5. The feeder system adopts anti-scratching protective measures, and elevating charging basket adopts plate-dragging organ, which may arrange the materials regularly and also reduce the impacts and noises.

we are offering Bar Straightening MachineThis device is a vertical straightening machine with multiple skew rolls (mainly seven-roll), mainly comprised of straightening machine and feeder system, and equipped with the corresponding electric control, hydraulic, pneumatic and lubricative devices. Obviously, it can resolve head-tail bends, eliminate slight ovality and remove oxidized iron sheet. Main characteristics: 1. Adopt optimized quasi-double curve and deep/shallow concave (evolved from convex and concave roll) shape complex rolling system, absorb the advantages of straightener with two-roll and traditional multiple skew rolls, and overcome both shortcomings, so the straightening precision is higher.2. Adopt the principle of double rolls pressing with controllable load, turn rigid frame into flexible one, and ensure necessary pressure on bar, thus expand the scope of bar plastic area, which can improve the straightening precision and protect mechanical equipments from damages.3. Main transmission adopts SIMENS's full-digital DC (or AC) 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, and the torque is balanced under load status, thus motor performance can be fully reflected.4. The programme control adopts the PLC system, and uses PROFIBUS-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. All operations are performed on the operating platform.5. The hydraulic system, equipped with hydraulic station, 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.6. The feeder system has a variety of options for users, so as to better meet the use requirements.
