Operation principle of the present utility model:
When the utility model normally works; three-phase power circuit is connected in series three groups of protection switch QF1; protection switch QF1 adopts model to be the breaker of DZ108; there is short-circuit protection and overload protection function; when bar cropper internal circuit is short-circuited fault or motor M generation overload fault; protection switch QF1 automatic trip, to ensure that circuit and motor M can not be burnt.
The utility model has auto-oiled function: as shown in Figure 2, the microprocessor R that self-service petrol pump YB self-acting lubricator is provided with according to top sets, memory time parameter, control the operation of packaged reducer, drive the worm gear being positioned at pump inside, by the lubricating grease in the reciprocating motion suction/jetting container of vertical piston.Self-service petrol pump YB self can set injecting time interval as required, the size of injection flow, can according to the parameter value set, often cross certain hour (rule of thumb, general setting 30min) automatic oil spout, each jet lubrication oil time is 3-5min, the lubricating oil ejected injects lubrication place by corresponding oil pipe mouth, oil pipe H can adopt flexible pipe or anticorrosion, resistant to elevated temperatures plastic rigid pipe, by consistent lubricant pipe H1, H2, H3, H4 is installed on bar cropper enclosure interior to be needed on the parts of lubrication, recycling end pump nozzle carries out localized ejection, oil filler point of the present utility model is respectively by consistent lubricant pipe H1, consistent lubricant pipe H2, consistent lubricant pipe H3, consistent lubricant pipe H4 is arranged at plug-in gear, clutch inner sleeve, on moving knife slideway and bent axle position, reach injection at regular time and quantity, reduce operating personnel's workload, improve service life of equipment.After the lubricating oil in self oil can is finished using, according to the warning system of device interior, automatically can send chimes of doom, remind operating personnel to refuel; Meanwhile, also can by inner normally-closed contact circuit, control appliance forced stoppage, thus the service life of improving equipment.Self-service petrol pump YB belongs to existing mature technology, does not repeat them here.
The utility model has the function of Auto-counting: as shown in Figure 1, automatic counting mechanism comprises circuit for controlling motor and counting circuit, circuit for controlling motor comprises motor M, motor M connects three-phase power circuit by three groups of main contact KM1 of A.C. contactor, current relay coil KA is in series with in the stator coil circuit of motor M, the first end of ac contactor coil KM is successively by counter normally-closed contact CT1, first hand push button SB1 connects the live wire U of three-phase power circuit, second end of ac contactor coil KM connects the zero line W of three-phase power circuit, counter normally-closed contact CT1 two ends are parallel with manual rotary switch SA1, first hand push button SB1 two ends are parallel with the series circuit that auxiliary contact KM2 often opened by the second hand push button SB2 and A.C. contactor, described counting circuit comprises counter CT, and counter CT accesses three-phase power circuit, and the counting terminal 1,3 of counter CT connects the normally opened contact KA1 of electric current relay.
When the utility model normally counts, first controlled the start/stop of motor M by circuit for controlling motor, when pressing the first hand push button SB1, closed circuit is (when the first hand push button SB1 presses, closed; When unclamping, automatically upspring, disconnect, instant circuit during work), now, second hand push button SB2 is in normally closed state, A.C. contactor and often opens auxiliary contact KM2 and be in off-state, then rotary manual rotary switch SA1, makes manual rotary switch SA1 be in the position of disconnection, counter normally-closed contact CT1 is in closed state, now, the loop conducting at ac contactor coil KM place, ac contactor coil KM obtains electric; Electric after, three groups of main contact KM1 of A.C. contactor and A.C. contactor are often opened auxiliary contact KM2 and are closed simultaneously, and power circuit residing for motor M is connected, and obtains electric work.During due to the first hand push button SB1 work, instantaneous conducting, now, A.C. contactor often leaves auxiliary contact KM2 and closes, circuit for controlling motor is held by live wire U and is often opened auxiliary contact KM2 by the second hand push button SB2, A.C. contactor successively, counter normally-closed contact CT1, ac contactor coil KM arrive zero line W and hold, now, circuit for controlling motor reaches steady-working state, motor M steady operation.
When motor M normally works, for bar cropper provides the power of cutting.First, the working condition of bar cropper is impingement load, namely when the edge of a knife of bar cropper impacts when workpiece (being generally reinforcing bar) is upper, load increases suddenly, after workpiece is blocked fast, load declines rapidly again, in the process, when load increases suddenly, the rotating speed of motor M can decline rapidly, and the electric current in motor M stator coil can increase rapidly, after workpiece is truncated, load declines rapidly again, and the rotating speed of motor M rises rapidly again, and the electric current in motor M stator coil reduces rapidly again.So, series connection access current relay coil KA in the stator coil circuit of motor M, when motor M stator coil electric current increases, the coil of electric current relay produces strong magnetic field, operating current relay normally open contact KA1 is driven to close, when motor M stator coil electric current reduces, current relay coil KA field weakening, electric current relay normally opened contact KA1 resets disconnection under the action of the spring.Namely when bar cropper blocks workpiece, load increases rapidly, and electric current relay normally opened contact KA1 closes, immediately after workpiece is truncated fast, load declines rapidly, electric current relay normally opened contact KA1 disconnects again immediately, electric current relay normally opened contact KA1 is connected on the counting terminal of access counter CT, is once closed into disconnection when electric current relay normally opened contact KA1 completes, also just complete and once count, that is, often block a workpiece, just complete and once count.Counter CT sets count number, when the number of times counted reaches the count number of setting, the A.C. contactor normally-closed contact that counter CT inside is arranged is disconnected, make ac contactor coil KM dead electricity, A.C. contactor three groups of main contact KM1 are disconnected, motor M shuts down, and bar cropper quits work.
The utility model controls the start/stop of motor mainly through circuit for controlling motor, and by being series at the curent change in the electric current relay perception coil of stator of motor in the stator coil circuit of motor, when being connected to after the electric current relay normally opened contact on rolling counters forward terminal completes the action being once closed into disconnection, also just complete and once count, can automatic gauge workload, increase work efficiency; Further, injection is at regular time and quantity carried out at wheel, clutch inner sleeve, moving knife slideway and bent axle position to utilize self-service petrol pump externally to mention, reduces operating personnel's workload, improves service life of equipment.
