Transform with PLC go runner lathe

61 document label piles up: B one, transform lathe with PLC the company purchased 1996 annulus firm go runner lathe, its main shaft, hydraulic pressure and mechanical drive all use relay to control, wiring is complex, trouble is more. To reduce breakdown, improve machine tool dependability and product quality, we use OMRON CPM1A-40DR-A to be able to make up Cheng controller to undertake transforming to this machine tool. 1. The treatment condition that the system designs this equipment is round of firm card to turn closely in top spin of main shaft chuck, cutting tool is installed go up at slip, slip moves quickly first drop, come up against cutting of feed of stage of decelerate spacing backward slip, till stage of backward slip of runner take out rises, complete process of a treatment. Decide the input signal of PLC and drive load according to afore-mentioned working procedure. Input signal includes to the hand is moved and automatic, refrigeration is opened and stop, slip falls and go up, hydraulic pressure is opened and stop, main shaft is opened and stop, pneumatic locking and loose etc in all at 19 o'clock, output is at 10 o'clock, choose OMRON 24 finally to be nodded certainly, the CPM 1 A-40CDR-A that went out at 16 o'clock undertakes controlling. 2. To program allocates good address to input and output signal, the design gives the electric principle picture of PLC, and the blueprint that exterior hardware hookup and installation place need other. The basis controls a demand, the picture gives program flow chart () laying a plan, give echelon picture according to flow chart design next. 2, after transforming the effect and benefit, simplified greatly to control route. PLC can use AC 220V tension directly, and can be outputted + 24V volts d.c. , mix for each electromagnetism a powerful person other yuan parts of an apparatus is used, reduced + 24V direct current source is outputted board. PLC pilot comes true, raised the sex of on the safe side of equipment greatly. Make maintenance work goes easily simply. Close after transform 1 year in moving, basically assured equipment everyday the successive and normal movement of 24h, system of device control character so far breakdown is basically 0. CNC Milling
