【摘要】：隨著我國經(jīng)濟(jì)的快速發(fā)展,建筑業(yè)和制造業(yè)規(guī)模不斷擴(kuò)大,對角鋼等金屬型材切割機(jī)的需求量也不斷增加。目前我國的一些中小型金屬型材加工企業(yè)仍以手動和半自動切割方式對金屬型材進(jìn)行切割。傳統(tǒng)手動和半自動的金屬型材切割機(jī)由于在加工效率、加工精度等方面滿足不了使用要求,因此急需一種自動程度及尺寸精度較高的金屬型材切割機(jī)。本文根據(jù)用戶的要求對QD160L金屬型材切割機(jī)進(jìn)行自動化改造。以PLC為控制平臺進(jìn)行自動順序控制,以觸摸屏為人機(jī)界面對設(shè)備的運(yùn)行狀態(tài)、參數(shù)進(jìn)行監(jiān)測及管理。在提高金屬型材切割機(jī)的加工效率和加工精度方面具有重要的意義。通過對國內(nèi)外切割機(jī)現(xiàn)狀的了解,根據(jù)以往金屬型材切割機(jī)的不足提出改造要求,設(shè)計(jì)切割機(jī)的改造實(shí)施方案,建立了自動化切割機(jī)的硬件平臺,選擇伺服電機(jī)為進(jìn)料裝置的動力源,經(jīng)過齒輪齒條的動力傳遞實(shí)現(xiàn)進(jìn)料裝置的直線運(yùn)動。采用STEP 7-Micro WIN SMART程序編程軟件對控制系統(tǒng)進(jìn)行程序設(shè)計(jì),以Win CC flexible圖形化編程軟件對觸摸屏進(jìn)行人機(jī)界面設(shè)計(jì)。按照位置控制的運(yùn)動模式對伺服電機(jī)進(jìn)行外部接線和參數(shù)設(shè)置,對伺服電機(jī)的運(yùn)動控制進(jìn)行組態(tài),對夾緊裝置和切斷裝置中的壓力檢測元件進(jìn)行選型和PLC的控制連接,在切割機(jī)的進(jìn)料口和出料口增加安全光幕實(shí)現(xiàn)系統(tǒng)的安全運(yùn)行,提高切割機(jī)的可靠性。通過以太網(wǎng)通訊的方式實(shí)現(xiàn)計(jì)算機(jī)、PLC和觸摸屏之間的通訊。切割機(jī)的自動化改造實(shí)現(xiàn)了對角鋼等金屬型材的精確定位,可以進(jìn)行自動加工,按照用戶的要求對金屬型材進(jìn)行不同長度的切割加工,設(shè)備的控制和運(yùn)行狀態(tài)都可以在可視化的觸摸屏上操作,提高了切割機(jī)的加工效率和產(chǎn)品的加工質(zhì)量,具有重要的應(yīng)用價(jià)值。
[Abstract]:With the rapid development of China's economy, the scale of construction and manufacturing industry is expanding, and the demand for metal profile cutting machines such as angle steel is also increasing. At present, some small and medium-sized metal profile processing enterprises still cut metal profiles by manual and semi-automatic cutting. Because the traditional manual and semi-automatic metal profile cutting machine can not meet the requirements of machining efficiency and machining precision, it is urgent to have a metal profile cutting machine with high automatic degree and dimension precision. According to the user's request, this paper automates the QD160L metal profile cutting machine. PLC is used as the control platform for automatic sequential control, and the touch screen is used as the man-machine interface to monitor and manage the running state and parameters of the equipment. It is of great significance in improving the machining efficiency and precision of metal profile cutting machine. Based on the understanding of the current situation of cutting machines at home and abroad, and according to the shortcomings of metal profile cutting machines in the past, this paper puts forward the reform requirements, designs the implementation scheme of the transformation of the cutting machines, and establishes the hardware platform of the automatic cutting machines. The servo motor is chosen as the power source of the feed device, and the linear movement of the feed device is realized through the power transfer of the gear rack. The control system is programmed by STEP 7-Micro WIN SMART, and the man-machine interface is designed by Win CC flexible. According to the motion mode of the position control, the external wiring and parameter setting of the servo motor are carried out, the motion control of the servo motor is configured, the pressure detecting elements in the clamping device and the cutting device are selected and the PLC control connection is carried out. The safe light screen is added to the feed and discharge ports of the cutting machine to realize the safe operation of the system and to improve the reliability of the cutting machine. The communication between PLC and touch screen is realized by Ethernet communication. The automatic transformation of the cutting machine realizes the precise positioning of metal profiles such as angle steel, and can be processed automatically, cutting metal profiles of different lengths according to the requirements of users. The control and running state of the equipment can be operated on the visual touch screen, which improves the machining efficiency of the cutting machine and the processing quality of the products, and has important application value.
