Abstract
The utility model discloses an electric control system for a punching machine, which comprises a switch part, a control part and an implementation part, wherein the control part is a PLC (Programmable logic Controller); the switch part is connected with the input end of the PLC; the implementation part comprises an alternating current contactor connected with the output end of the PLC and the reduced-voltage starting circuit of the electric motor of the punching machine and an electromagnet which is used for controlling a slide block to move downwards and connected between the output end of the PLC and a power supply; the switch part can comprise a foot pedal switch, a starting switch, a stop switch, an inching/automatic switch and an FR thermal protection switch; a counter is further connected between the output end of the PLC and the power supply; and the electric control system for the punching machine is reliable in operation, has few faults, convenience for maintenance and convenience for operational parameter adjustment.
Description
Technical field
The utility model relates to the electric-control system of punch press.
Background technology
Traditional punch press electric-control system generally will comprise switch sections, control section, operating part; Switch sections will comprise that generally starting switch, shutdown switch, floor push etc. send the switch of instruction; Control section generally will comprise a plurality of auxiliary reclays and the time relay; Be used for instruction that receiving key partly sends and control the action of operating part then; Operating part generally will comprise a plurality of contactors, electromagnet, electric motor starting circuit etc., and the action through operating part makes the operation of punch press motor or stops, and makes the slide block down of punch press or stops etc.; This traditional electric-control system is more because of the electronic devices such as relay that need adopt, and brings the contact many, and joint is many, the circuit bulky complex, and therefore the fault rate of operation is higher, and overhauls also more time-consuming, trouble; The operational factor of this electric-control system is fixed simultaneously, is difficult to adjustment.
The utility model content
The technical problem that the utility model will solve provides a kind of electric-control system of punch press, and it is reliable, fault is few, easy to maintenance and operational factor is easy to adjust.
For achieving the above object; The technical scheme of the utility model is: a kind of electric-control system of punch press; Comprise switch sections, control section, operating part; Described control section is the PLC plc, and said switch sections is connected in the input of PLC, the electromagnet that described operating part comprises the A.C. contactor that connects PLC output and punch press motor reduced-voltage starting circuit and is connected in control slide block down between PLC output and the power supply.
Preferred said switch sections comprises floor push, starting switch, shutdown switch, crawl/automatic switch, FR heat portective switch.
Said switch sections also comprises backup circuit breaker, uses when being used to develop new function.
Further improve, also be connected with counter between described PLC output and the power supply, can write down the descending number of times of slider of punch, the output of convenient statistics punching parts.
The utility model is owing to select for use the PLC plc to substitute electronic devices such as a plurality of auxiliary reclays and the time relay as control section; Reduce numerous terminals and contact; Make whole connection line succinct, reliable, thus whole system is reliable, fault is less, easy to maintenance; On the other hand, revise operational factor, as long as the programming of change PLC, the operational factor adjustment is very convenient.
The utility model can also be realized on-line monitoring failure judgement point fast, reduces the downtime that failover causes.
Description of drawings
Fig. 1 is the utility model principle schematic.
The specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is done further explain.
Shown in Figure 1; A kind of electric-control system of punch press; Comprise switch sections 1, control section 2, operating part 3, power unit 4; Switch sections 1 can comprise floor push 11, starting switch 12, shutdown switch 13, crawl/automatic switch 14, FR heat portective switch 15, and switch sections 1 also can comprise backup circuit breaker 16;
Described control section 2 is selected the PLC plc for use, and said switch sections 2 is connected in the input of PLC;
Described operating part 3 comprises three A.C. contactors 31, electromagnet 32, punch press motor 6 reduced-voltage starting circuit 33; Three A.C. contactors 31 are connected between PLC output and the punch press motor 6 reduced-voltage starting circuit 33, and electromagnet 32 is connected in the operation that is used to control slider of punch between PLC output and the power unit 4;
Between described PLC output and power unit 4, also be connected with counter 5, described counter 5 can write down the descending number of times of slider of punch;
PLC returned by power unit 4 and punch press motor reduced-voltage starting circuit 33 provides power supply.
Described starting switch 12 is used to make motor 6 runnings with shutdown switch 13 and stops;
The keying of described floor push 11 control electromagnet 32 makes the slide block action of punch press;
Described crawl/automatic switch 14 is used to control the slide block crawl of punch press or operation continuously;
During 15 actions of described FR heat portective switch motor 6 is shut down and be used for the overtemperature protection of motor 6.
Below only be preferred embodiment of the utility model, the change that those skilled in the art does to be equal to by claim all falls into the protection domain of this case.
