Summary of the invention
The utility model purpose is to provide a kind of low cost of manufacture, safe and reliable stirrup bender intelligent controller.
For realizing above-mentioned purpose, the utility model can be taked following technical proposals:
The described stirrup bender intelligent controller of the utility model comprises microcontroller, and said microcontroller sampled signal input end is connected with the angular position sensor unit output terminal of being made up of Hall element; Be connected with bending angle control keyswitch in the control input end of microcontroller; The control output end of microcontroller is connected with the forward and backward control circuit of stirrup bender drive motor; The power input of microcontroller is connected with power supply through step-down transformer.
The forward and backward control circuit of said stirrup bender drive motor comprises: the forward and backward A.C. contactor; Coil one end of said forward and backward A.C. contactor is connected with power supply respectively, just delivering stream contactor coil the other end through the counter-rotating A.C. contactor normally closed contact be connected with a control output end of microcontroller; The other end of counter-rotating ac contactor coil is connected with another control output end of microcontroller through the normally closed contact of just delivering the stream contactor; The normally opened contact of forward and backward A.C. contactor is series at respectively in the power circuit of stirrup bender drive motor with parallel way.
The utility model advantage is to select, control reinforcing bar bending angle through keyswitch that is connected in said microprocessor controls input end and angular position sensor unit, and therefore, control response speed is fast, Control current is little, the control angular setting is convenient; Also can place embedding that, shake-proof ability dustproof to improve are arranged in the airtight box of insulation silica gel microcontroller; Simultaneously, little, the low cost of manufacture, safe and reliable of the utility model volume.
Description of drawings
Fig. 1 is the circuit theory diagrams of the utility model.
Embodiment
As shown in Figure 1, the described stirrup bender intelligent controller of the utility model comprises microcontroller, and said microcontroller sampled signal input end is connected with the angular position sensor unit output terminal of being made up of Hall element; Be connected with bending angle control keyswitch k1, k2 in the control input end of microcontroller; The control output end of microcontroller is connected with the forward and backward control circuit of stirrup bender drive motor D; The power input of microcontroller is connected with power supply through step-down transformer B.The forward and backward control circuit of said stirrup bender drive motor D comprises: forward and backward A.C. contactor J1, J2; Coil one end of said forward and backward A.C. contactor J1, J2 is connected with power supply respectively, and the other end of just delivering stream contactor J1 coil is connected with a control output end of microcontroller through the normally closed contact j21 of counter-rotating A.C. contactor J2; The other end of counter-rotating A.C. contactor J2 coil is connected with another control output end of microcontroller through the normally closed contact j11 that just delivers stream contactor J1; Normally opened contact j12, the j22 of forward and backward A.C. contactor J1, J2 are coupled to respectively in the power circuit of stirrup bender drive motor D with the parallel way string.
The utility model principle of work is following:
As shown in Figure 1; Step-down transformer B secondary winding provides 9 volts of voltages as working power to microcontroller, when pressing 90 degree keyswitch k1 (foot-switch), is just delivering stream contactor J1 and is getting; Its normally opened contact j12 is closed, and stirrup bender drive motor D is just transporting row; When equipment operation is spent the Hall element detection positions to 90 of angular position sensor unit; The Hall element of 90 degree position probing sends signal to microcontroller; Just delivering stream contactor J1 dead electricity, its normally opened contact j12 breaks off, and counter-rotating A.C. contactor J2 gets; Its normally opened contact j22 is closed, the stirrup bender drive motor D operation of reversing; When equipment was got back to zero-bit, microcontroller stopped control output signal, and D is out of service for the stirrup bender drive motor.
When pressing 135 degree keyswitch k2 (foot-switch), the course of work is the same.
