扭軸數(shù)控折彎機的工作原理如下：

• 動力與傳動：扭軸數(shù)控折彎機通常由電機提供動力，通過液壓系統(tǒng)或機械傳動裝置將動力傳遞到各個工作部件。在液壓傳動的扭軸數(shù)控折彎機中，電機驅(qū)動油泵，將液壓油加壓并輸送到各個液壓缸，通過液壓缸的伸縮來實現(xiàn)滑塊的上下運動以及其他輔助動作。而在一些采用機械傳動的折彎機中，電機通過皮帶、齒輪或絲杠等傳動機構(gòu)帶動滑塊運動。

• 扭軸同步原理：扭軸數(shù)控折彎機的關(guān)鍵在于扭軸同步機構(gòu)。扭軸是一根貫穿于折彎機兩側(cè)的軸，當滑塊進行折彎動作時，扭軸會發(fā)生扭轉(zhuǎn)。扭軸的扭轉(zhuǎn)角度與滑塊的行程以及折彎力之間存在著一定的比例關(guān)系。通過精確控制扭軸的扭轉(zhuǎn)，可以實現(xiàn)兩側(cè)滑塊的同步運動，保證折彎精度。具體來說，當一側(cè)滑塊受到的阻力較大時，扭軸會將扭矩傳遞到另一側(cè)滑塊，使得兩側(cè)滑塊能夠保持同步，避免出現(xiàn)折彎角度不一致或板材扭曲等問題。

• 數(shù)控系統(tǒng)控制：數(shù)控系統(tǒng)是扭軸數(shù)控折彎機的大腦，操作人員通過數(shù)控系統(tǒng)輸入折彎參數(shù)，如折彎角度、長度、速度等。數(shù)控系統(tǒng)根據(jù)這些參數(shù)計算出滑塊的運動軌跡和扭軸的扭轉(zhuǎn)角度，并向各個執(zhí)行部件發(fā)送控制信號。在折彎過程中，數(shù)控系統(tǒng)會實時監(jiān)測滑塊的位置和扭軸的狀態(tài)，通過反饋機制不斷調(diào)整控制信號，以確保實際折彎過程與預(yù)設(shè)參數(shù)相符。例如，如果發(fā)現(xiàn)滑塊的運動速度偏離了預(yù)設(shè)值，數(shù)控系統(tǒng)會自動調(diào)整液壓流量或電機轉(zhuǎn)速，使滑塊回到正確的運動軌跡上。

• 模具作用：模具是扭軸數(shù)控折彎機實現(xiàn)板材折彎的直接工具。上模和下模分別安裝在滑塊和工作臺上，當滑塊下行時，上模與下模閉合，對置于其間的板材施加壓力，使板材發(fā)生塑性變形，從而實現(xiàn)折彎。不同的折彎形狀和尺寸需要使用相應(yīng)的模具，通過更換模具，可以滿足各種不同的折彎工藝要求。

• Power and Transmission: The torsion shaft CNC bending machine is usually powered by an electric motor, and the power is transmitted to each working component through a hydraulic system or a mechanical transmission device. In a torsion shaft CNC bending machine with hydraulic transmission, the electric motor drives an oil pump to pressurize the hydraulic oil and deliver it to each hydraulic cylinder. The expansion and contraction of the hydraulic cylinders are used to achieve the up-and-down movement of the slider and other auxiliary actions. In some bending machines using mechanical transmission, the electric motor drives the slider to move through transmission mechanisms such as belts, gears or lead screws.

• Principle of Torsion Shaft Synchronization: The key of the torsion shaft CNC bending machine lies in the torsion shaft synchronization mechanism. The torsion shaft is a shaft running through both sides of the bending machine. When the slider performs the bending action, the torsion shaft will twist. There is a certain proportional relationship between the torsion angle of the torsion shaft, the stroke of the slider and the bending force. By precisely controlling the torsion of the torsion shaft, the synchronous movement of the sliders on both sides can be achieved, ensuring the bending accuracy. Specifically, when the resistance on one side of the slider is relatively large, the torsion shaft will transmit the torque to the slider on the other side, enabling the sliders on both sides to remain synchronized and avoiding problems such as inconsistent bending angles or sheet metal distortion.

• Control of the CNC System: The CNC system is the brain of the torsion shaft CNC bending machine. The operator inputs bending parameters such as the bending angle, length, and speed through the CNC system. The CNC system calculates the movement trajectory of the slider and the torsion angle of the torsion shaft according to these parameters, and sends control signals to each executing component. During the bending process, the CNC system will monitor the position of the slider and the status of the torsion shaft in real time, and continuously adjust the control signals through the feedback mechanism to ensure that the actual bending process conforms to the preset parameters. For example, if it is found that the movement speed of the slider deviates from the preset value, the CNC system will automatically adjust the hydraulic flow or the rotational speed of the motor to make the slider return to the correct movement trajectory.

• Function of the Dies: The dies are the direct tools for the torsion shaft CNC bending machine to achieve sheet metal bending. The upper die and the lower die are respectively installed on the slider and the worktable. When the slider moves downward, the upper die and the lower die close, applying pressure to the sheet metal placed between them, causing the sheet metal to undergo plastic deformation, thus achieving bending. Different bending shapes and sizes require corresponding dies. By replacing the dies, various different bending process requirements can be met.
