棒料切割機及 PLC 控制設(shè)計I摘 要本次設(shè)計主要做出了棒料切割機及 PLC 控制設(shè)計切割部分、夾緊部分、縱橫行走部分等機械部分,切割機的電氣控制線路和 PLC 自動控制等控制部分,切割機的氣壓系統(tǒng)等傳動部分的設(shè)計。為了降低生產(chǎn)成本,提高生產(chǎn)效率要求切割機必須能夠?qū)崿F(xiàn)較高精度的定長切割,必須有較快的運動速度及運動精度,在這樣的要求下我及我公司多位同仁的共同努力下,經(jīng)過多次的實驗改進終于做出了DJ-01 這臺較優(yōu)秀的金屬棒料切割機,它的工作是由 PLC 控制電磁閥,使電磁閥控制氣缸,并由氣缸驅(qū)動與其連接的部件,實現(xiàn)對棒料的準確定長切割,切割后自動返回初始位置。一個切割機分別切割兩條鎢棒,其切口深度為 35mm,然后由壓斷機進行壓斷。從我們的實際使用情況來看這臺機器操作簡便,運行穩(wěn)定、維護方便等優(yōu)點,大大的提高了生產(chǎn)效率。該產(chǎn)品性能良好,不但能切鎢棒,還可以切割其他的金屬棒料并且功耗小可以廣泛應(yīng)用。關(guān)鍵詞:自動控制,切割,PLC棒料切割機及 PLC 控制設(shè)計IIABSTRACTThis design made the DJ-01 main bar cutting machine to cut parts, clamping parts, mechanical parts such as vertical and horizontal moving parts, cutting machines electrical control circuits and PLC automatic control, control parts, cutting machine pneumatic systems, transmission parts design. In order to reduce production costs, improve production efficiency requirements cutting machine must be able to achieve higher precision fixed-length cutting, there must be a faster movement speed and movement precision, such a request in for me and my company the joint efforts of many colleagues, After several experiments to improve the DJ-01 has finally made this station a more excellent cutting machine metal sticks, which is handled by the PLC control solenoid valve, solenoid valve to control the cylinder by cylinder drive connected components, to achieve the accuracy of the bar fixed-length cutting, cutting back to initial position automatically. A cutting machine cutting two tungsten rods, respectively, the incision depth of 35mm, then the pressure off machine pressure off. From our perspective the actual use of the machine easy to operate, stable running, easy maintenance and so greatly improved the production efficiency. Good performance of the product, not only can cut tungsten rod, you can also cut the other Metal Rod and power consumption can be widely used.KEY WORDS: Automatic Control, cut, PLC棒料切割機及 PLC 控制設(shè)計3目 錄前 言 .1第 1 章 切割機的整體結(jié)構(gòu) .2第 2 章 切割部分設(shè)計 .32.1 設(shè)計要求 32.2 方案設(shè)計 .32.3 結(jié)構(gòu)設(shè)計 .42.3.1 砂輪片的選取 .42.3.2 電機的選取 .42.3.3 帶傳動設(shè)計 .42.3.4 升降氣缸的選擇 .82.3.5 滾動軸承的選取及校核 10第 3 章 夾緊部分設(shè)計 .143.1 設(shè)計要求 143.2 方案設(shè)計 .14第 4 章 縱橫行走部分的設(shè)計 .164.1 4.1 設(shè)計要求 .164.2 方案設(shè)計 164.3 直線導(dǎo)軌的選擇計算 .164.3.1 選定條件: .164.3.2 選擇方式 .17棒料切割機及 PLC 控制設(shè)計4第 5 章 控制部分的設(shè)計 .195.1 電氣控制線路的設(shè)計 .195.2 氣動原理圖設(shè)計 .195.3 PLC 自動控制電路設(shè)計 .215.3.1PLC 的組成 215.3.2 可編程控制器的特點 22結(jié) 論 .24謝 辭 .26參考文獻 .27附 錄 .28外文資料翻譯 .32
