電氣控制系統(tǒng)：

Electrical control system:

電氣控制系統(tǒng)是整個設備的核心部分，設備的控制軟件安裝在MC運動控制器中。所有的控制指令運算工作輸入輸出信號系統(tǒng)狀態(tài)監(jiān)視，以及與操作人員的信息交流均由該部分完成。

The electrical control system is the core part of the entire equipment, and the control software of the equipment is installed in the MC motion controller. All control instruction calculations, input and output signal system status monitoring, as well as information exchange with operators, are completed by this section.

該系統(tǒng)采用松下支持RTEX總線的A6N伺服及電機。RTEX具有極高的性價比，采用RTEX總線控制系統(tǒng)后，客戶在不增加電機成本的情況下，大幅降低了配線安裝工作。100M的網(wǎng)絡帶寬和RTEX優(yōu)異的穩(wěn)定特性，確保了MC1002R與系統(tǒng)各個A6N伺服驅動器之間的控制周期能夠達到0.5ms，從而大幅提高了客戶機器的控制精度。

The system adopts Panasonic's A6N servo and motor that support RTEX bus. RTEX has a very high cost performance ratio. By adopting the RTEX bus control system, customers can significantly reduce wiring and installation work without increasing motor costs. The 100M network bandwidth and excellent stability characteristics of RTEX ensure that the control cycle between MC1002R and various A6N servo drivers in the system can reach 0.5ms, greatly improving the control accuracy of the customer's machine.

動力控制系統(tǒng)：

Power control system:

由數(shù)個氣動電磁閥相應氣路眾多氣動元件，以及控制信號回路組成氣動動力系統(tǒng)，負責完成設備復雜的程控動作。

The pneumatic power system is composed of several pneumatic solenoid valves, corresponding pneumatic circuits, numerous pneumatic components, and control signal circuits, responsible for completing complex programmable actions of the equipment.

觸摸屏軟件界面：

Touch screen software interface:

操作人員對設備的使用所需要的大量的數(shù)據(jù)輸入，以及操作人員需要了解的設備運行的信息，均通過觸摸屏來完成。

The large amount of data input required for the use of equipment by operators, as well as the information about the operation of the equipment that operators need to know, are all completed through the touch screen.

鋁條折彎的工藝流程

The process flow of aluminum bar bending

設備上電后，通過觸摸屏輸入鋁框圖形參數(shù)，踩下腳踏開關設備開始運行，控制系統(tǒng)通過判斷原料位置選擇自動上料流程還是直接進入自動折彎流程，并自動判斷當前原料的余料接頭位置是否出現(xiàn)在禁折區(qū)。步進給料系統(tǒng)將由控制系統(tǒng)計算后的料長精確的給進至折彎刀頭，由折彎系統(tǒng)完成需要的折彎形狀。

After the device is powered on, input the aluminum frame graphic parameters through the touch screen, press the foot switch, and the device starts running. The control system selects the automatic feeding process or directly enters the automatic bending process by judging the position of the raw materials, and automatically determines whether the position of the remaining material joints of the current raw materials is outside the prohibited folding area. The step feed material system will accurately feed the material length calculated by the control system to the bending blade, and the bending system will complete the required bending shape.

重復以上兩步，直至完成整個鋁框成形流程。

Repeat the above two steps until the entire aluminum frame forming process is completed.

在鋁框折彎過程中，隨時會出現(xiàn)當前加工的鋁條即將用完的情況，通過系統(tǒng)自動判斷可使后續(xù)鋁條自動續(xù)接至當前鋁條尾部，不中斷當前鋁條的成形工作。

During the bending process of the aluminum frame, there may be situations where the current processed aluminum bars are about to be used up. The system automatically determines that the subsequent aluminum bars can be automatically connected to the tail of the current aluminum bar without interrupting the forming work of the current aluminum bar.
