The lathe working method is: determine initial point → determine cutting parameter → saw frame locking → workpiece clamping → saw frame advance (worker advances).Determine that former naming a person for a particular job makes vertical saw frame automatically restore to origin position; Cutting parameter is the cutting angle and the cutting speed of cutting length, material;
In man-machine interface, enter duty, saw frame locking and workpiece clamp, saw frame advances, its speed is by the flow speed control valve step-less adjustment, when vertical saw frame advances to the high order end position and acts on the contactless infrared ray of front limit near switch, to PLC, vertical saw frame transfers rewind down to the front limit switch automatically with signal feedback.Act on the spacing contactless infrared ray in back during near the position of the switch when vertical saw frame retreats the low order end position, back limit switch arrives PLC with signal feedback, and vertical saw frame stops.
Described vertical saw frame advances or retreats by the mobile hydraulic oil cylinder driving that is installed in the coaster casing.When vertical saw frame begins to advance, pump motor and the also entry into service of main motor, main motor speed is by Frequency Converter Control.When handling lathe, it is in proper order:
1. determine the cutting angle of material: in man-machine interface, enter angle adjustment, select vertical saw frame initial point, vertical saw frame rotation, the contactless infrared ray by original point position is near switch, and to PLC, vertical saw frame will automatically restore to origin position with signal feedback.Input cutting angle (45 °-0-+45 °), vertical saw frame rotation, by rotary encoder, to PLC, the anglec of rotation is accurately located with signal feedback, and behind the location, by the rotary oil cylinder effect, vertical saw frame is with auto lock.
2. determine the cutting speed of material: in man-machine interface, enter the cutting speed adjustment, by the Frequency Converter Control cutting speed.
3, lathe feeding, the material returned: in man-machine interface, enter feeding, the material returned, determine the length of cut spare, workpiece is sent to or retreated by the feeding motor.
4. saw frame locking: enter saw frame locking in man-machine interface, lock vertical saw frame by locking cylinder and friction plate, locking cylinder remains locking state in working angles.
5. workpiece clamps: enter workpiece and clamp in man-machine interface, workpiece is clamped before cutting by the workpiece grip vice, remain the workpiece clamped condition in working angles.
The present invention adopts man-machine interface, and is simple to operate, by the vertical saw frame rotation of control automatically of PLC programmable logic controller (PLC), rotary encoder, saw frame whirligig and saw frame drive unit.During sawing machine work, when the certain angle of cutting material is wanted in input, just quick, the accurate location of lathe, and by saw frame tightening device auto lock.And vertical saw frame rotation angle range is-45 °-0-+45 °, and the scope of application is bigger.
