鋸床液壓傳動系統由泵、閥、油缸、油箱、管路等元輔件組成的液壓回路,在電氣控制下完成鋸梁的升降,工件的夾緊。通過調速閥可實行進給速度的無級調速,達到對不同材質工件的鋸切需要。電氣控制系統由電氣箱、控制箱、接線盒、行程開關、電磁鐵等組成的控制回路,用來控制鋸條的回轉、鋸梁的升降、工件的夾緊等,使之按一定的工作程序來實現正常切削循環。

潤滑系統開車前必須按機床潤滑部位(鋼絲刷軸、蝸輪箱、主動軸承座、蝸桿軸承、升降油缸上下軸、活動虎鉗滑動面夾緊絲桿)要求加油。蝸輪箱內的蝸輪、蝸桿采用30號機油油浴潤滑,由蝸輪箱上部的油塞孔注入,箱面備有油標,當鋸梁位于最低位置時,油面應位于油標的上、下限之間。試用一個月后應換油,以后每隔3-6個月換油1次,蝸輪箱下部設有放油塞。

鋸床鋸條傳動安裝在蝸輪箱上的電動機通過皮帶輪,三角膠帶驅動蝸輪箱內的蝸桿和蝸輪,帶動主動輪旋轉,再驅動繞在主動被動輪緣上的鋸條進行切削回轉運動。鋸條進給運動由升降油缸和調速閥組成的液壓循環系統,控制鋸梁下降速度從而控制鋸條的進給(無級調速)運動。鋸刷旋轉在鋸條出屑的地方,并隨著鋸床鋸條走鋸的方向旋轉,并由冷卻泵供冷卻液清洗,清除鋸齒上的切屑。冷卻液在底座的右側冷卻切削液箱里,由水泵直接驅動供冷卻液。

按緊停(停止)按鈕,順時針方向旋轉,油泵電機工作,齒輪泵工作,油液經過濾網進入管路,調節溢流閥使系統工作壓力達要求。反之按鈕向內壓,所有電機停止工作。工件夾緊按鉗緊按鈕,電磁閥工作,液壓油進入夾油缸左邊,右邊液壓油回油箱,左鉗向工件夾緊。

鋸床鋸梁下降按工作按鉗,液壓油通過電磁閥進入升降油缸有桿腔;無桿腔液壓油通過電磁閥,單向調速閥回油箱。鋸梁快降按下降按鈕,液壓通過電磁閥工作,油進入升降油缸有桿腔,無桿腔油通過電磁閥回油箱。鋸梁上升按上升按鈕,液壓油通過電磁閥進入升降油缸的無桿腔;有桿腔油經過電磁閥回油箱。工件松開按鉗松按鈕,液壓油通過電磁閥進入夾緊油缸右邊;左邊液壓油能過電磁閥回油箱,左鉗口向左運動工件松開。

系統的模擬輸入輸出模塊,使鋸削過程的監控具有廣泛的意義,如:鋸床只要增加鋸條變形的反饋,即可對鋸削速度進行自適應調整。增加伺服閥,即可對鋸削過程的速度和位置控制進行優化。系統的管理功能使材料和工件的管理更方便。系統的中文界面和實時的圖形狀態顯示,使操作更友好更直觀。

 

 

The hydraulic transmission system of sawing machine is composed of pump, valve, oil cylinder, oil tank, pipeline and other auxiliary parts. The lifting of saw beam and clamping of workpiece are completed under electrical control. The stepless speed regulation of feed speed can be realized through the speed regulating valve, so as to meet the sawing needs of different materials. The electric control system consists of electric box, control box, junction box, travel switch, electromagnet, etc. it is used to control the rotation of saw blade, lifting of saw beam, clamping of workpiece, etc., so as to realize normal cutting cycle according to certain working procedures. Before the start-up of the lubrication system, the lubricating parts of the machine tool (wire brush shaft, worm gear box, driving bearing seat, worm bearing, upper and lower shafts of lifting cylinder, clamping screw rod of sliding surface of movable vice) must be lubricated. The worm gear and worm in the worm gear box are lubricated with No. 30 oil bath. The oil is injected through the oil plug hole on the upper part of the worm gear box. There is an oil mark on the box surface. When the saw beam is at the lowest position, the oil level should be between the upper and lower limits of the oil level. The oil should be changed after one month of trial, and then every 3-6 months. The lower part of worm gear box is equipped with oil drain plug. The saw blade drives the motor installed on the worm gear box through the belt pulley and V-belt to drive the worm and worm gear in the worm gear box to drive the driving wheel to rotate, and then drive the saw blade around the active / passive flange for cutting and rotating. The feed motion of saw blade is composed of lifting cylinder and speed regulating valve, which controls the descending speed of saw beam and thus controls the feed (stepless speed regulation) movement of saw blade. The saw brush rotates at the place where the saw blade comes out of chips, and rotates along with the saw blade of the saw machine in the direction of sawing, and the coolant is supplied by the cooling pump to clean the chips on the saw teeth. The coolant is in the coolant tank on the right side of the base and is directly driven by the water pump to supply coolant. Press the emergency stop (stop) button and rotate clockwise. The oil pump motor works and the gear pump works. The oil enters the pipeline through the filter screen. Adjust the relief valve to make the system working pressure meet the requirements. Otherwise, press the button inward, all motors stop working. Press the clamp button to clamp the workpiece, the solenoid valve works, the hydraulic oil enters the left side of the clamping cylinder, the right side hydraulic oil returns to the oil tank, and the left clamp clamps the workpiece. When the saw beam of the sawing machine is lowered, press the working clamp, and the hydraulic oil enters the rod chamber of the lifting cylinder through the solenoid valve; the hydraulic oil in the rod free chamber flows through the solenoid valve, and the one-way speed regulating valve returns to the oil tank. When the saw beam is lowered quickly, the hydraulic pressure works through the solenoid valve. The oil enters the rod cavity of the lifting cylinder, and the oil in the non rod chamber returns to the oil tank through the solenoid valve. When the saw beam rises, press the up button, and the hydraulic oil enters the rod less chamber of the lifting cylinder through the solenoid valve; the oil in the rod chamber returns to the oil tank through the solenoid valve. When the workpiece is released, press the clamp release button, and the hydraulic oil enters the right side of the clamping cylinder through the solenoid valve; the left hydraulic oil can return to the oil tank through the solenoid valve, and the left jaw moves to the left, and the workpiece is released. The analog input and output module of the system makes the monitoring of sawing process have a wide range of significance. For example, as long as the feedback of saw blade deformation is increased, the sawing speed can be adjusted adaptively. The speed and position control of sawing process can be optimized by adding servo valve. The management function of the system makes the management of materials and workpieces more convenient. The Chinese interface and real-time graphical state display of the system make the operation more friendly and intuitive.
