Wall panel Proportional change compensation system Patent G-Reflex (China Invention Patent, Patent number ZL 2017 1 0296448.6)

The application of G-Reflex compensation system on G-T-OP bending machines ensures that every bending Angle is consistent throughout the entire length regardless of bending conditions changing with plate thickness, length or bending position. The typical and unavoidable problem of the bending machine is the "gaping" effect caused by the deformation of the wall panels of the cantilever structure under the reaction force during the bending process. If the grating ruler used to measure the travel is directly fixed on the side wall panel, the "gaping" deformation will lead to the measurement error of the grating ruler. To avoid this phenomenon, an additional "c" frame is bolted to the bottom two sides of the lower beam of our G-T O P bending machine for connecting the grating ruler. Since this additional "c" frame is independent of the frame body structure, it does not deform with the deformation of the wall panel described above during bending, thus ensuring the accuracy of the machine.

After the installation of the G-Reflex compensation system, the actual position of the upper beam is detected by two grating gauges installed on the self-adjusting balancing device and the separate deformation-free additional "C" frame. Therefore, during bending, the G-Reflex compensation system will automatically measure the grating error according to the amount of deformation of the wall panel "opening".

CNC real-time automatic compensation system G-CS

The LAG's innovative CNC real-time automatic compensation system G-CS is one of the deflection compensation systems that represent CNC technology in today's global bending machine market. At the same time, thanks TO the use of innovative automatic disturbance compensation system G-CS, wall panel variation compensation system G-Flex and machined bolted fuselage structure technology, the G-T-O P series bending machine has the characteristics of bending accuracy and high stability.

The core innovative technology G-CS automatic compensation system refers to: in the process of bending, the CNC system outputs the corresponding compensation value according to the real-time deformation of the upper and lower beams to drive the compensation cylinder for dynamic compensation. The compensation process is a closed-loop control process in which two potentiometers installed on the upper and lower beams collect the deformation data in real time and send the dynamic compensation value to the separate hydraulic compensation system automatically through the numerical control system.

All conventional deflection compensation systems are calculated based on empirical values or pre-set the amount of deformation of the beam and then multiple test breaks, because this is uncontrollable. In theory, each bending material change, the distribution of holes or bending at different positions in the bending machine may change the deformation value of the set beam, so theoretical expectations, bending tests and calculations can not fundamentally solve these problems. The end result is that the bending Angle is not the value you programmed.

The G-CS automatic torsion system simplifies the complex test bending process under the condition that the plate thickness is unchanged. Even if the length of the bending workpiece is different, or the bending machine can be automatically realized by the G-T O P bending machine to ensure the bending of the same Angle and straightness of the workpiece. The operator no longer needs to adjust the input preset compensation value based on experience and bending length changes.

Rear stop System (X-R-Z 1-Z2)

As a guarantee of the dimensional accuracy of bending products, the back stop system is an important part to ensure the bending accuracy of the bending machine. The 4-axis (x-R-zl-zz) rear stopper of the G-T OPE series standard models ensures flexible, high-speed positioning of almost all complex bending workpieces.

The processing surface of the side plate is the datum surface and the linear guide rail and the pinion and rack transmission mode can ensure the parallel of the left and right support surface of the rear material beam without adjustment. Thanks to the rack and pinion drive with anti-backlash technology, the fast speed is up to 600mm/ s.

The left and right support of the rear beam of the combination of aluminum and steel parts can be fine-tuned to the X-axis and R-axis directions by means of a wedge mechanism, reflecting LAG's pursuit of the bending process.

The rear stopper beam uses steel pipe as the main structure to ensure that the beam is strong and not deformed. The special aluminum alloy profile above the steel pipe ensures the dynamic acceleration of the beam and the flexible demand of the rear stop finger, and can be adjusted in the straightness and height of any position within the full length of the aluminum alloy beam.

The highly integrated LAG design of the X-R shaft fully enclosed self-lubricating integrated transmission, with direct dual drive transmission mode, to achieve reliable transmission while ensuring synchronization accuracy of the left and right directions.

Rear stop finger anti-collision function (China Invention Patent, Patent No. ZL 2017 1 0735450.9)

The standard rear stop is configured with two CNC stop fingers (Z1-Z2). When the rear stop finger is impacted in the case of misoperation, the stop finger block will be opened from the base to avoid damage to the accuracy of the rear stop material and better ensure the operator's personal life.

Pneumatic expansion bracket GRP-R

At the beginning of bending positioning, the GRP-R pneumatic expansion bracket, which is combined with the zi-zz stop finger into a whole system and moves together with them along the z axis, extends to support the plate between the back stop finger and the lower die. After the upper die presses the plate, the GPR-R is withdrawn and gives way with the back stop finger. The device is useful for bending large panel products, the operator can bend continuously in the same feeding direction, without turning, bending efficiency and accuracy.

The brush table on the surface of the pneumatic retractable bracket ensures that the metal surface is scratch free.

Manually slide the front bracket

The high rigidity composite structural front bracket is manually sliding along the linear guide rail in the Z-axis direction through the roller support, and the height can be easily adjusted by the handle. Special extended lower beam with parking space can be selected for the pallet as required.
