Abstract
The utility model discloses a soft starter-based multidirectional forging hydraulic press control device, belonging to the technical field of a hydraulic press. The soft starter-based multidirectional forging hydraulic press control device is characterized in that a soft starter is arranged between a main pump motor and a power supply of a multidirectional forging hydraulic press, and electrically connected with the main pump motor by a relay. The soft starter is arranged between the main pump motor and the power supply of the multidirectional forging hydraulic press, and used for controlling overload impulse current or overload voltage, so that the damage of the overload impulse current or overload voltage to the main pump motor of the multidirectional forging hydraulic press can be reduced, thus effectively protecting the safety running of the multidirectional forging hydraulic press, nibbing in the bud, lowering the maintenance cost of the multidirectional forging hydraulic press, and prolonging the service life of the multidirectional forging hydraulic press.
Description
Technical field
The utility model belongs to hydraulic press technical field, particularly relates to a kind of multiway forging hydraulic press control device based on soft initiator.
Background technology
In recent years, fast development along with forging industry, it is more and more higher that industry requires to become to the security performance of hydraulic press, at present, multiway forging technique, as a kind of forming technique more recently of applying in the world, has stock utilization high, manufacture process clean and effective, production cost is low, can manufacture feature complex-shaped and that be difficult to machine cut processing, in fields such as automobile, Aero-Space, national defence, has a wide range of applications.But find by practice, in the process of using, due to the existence of overload impact electric current or overload voltage, brought great potential safety hazard therefore to the normal operation of multiway forging hydraulic press, increase maintenance cost, reduced the service life of multiway forging hydraulic press simultaneously.
Summary of the invention
Goal of the invention of the present utility model is: overcome the above-mentioned defect of prior art, propose that a kind of overload impact electric current is controlled, maintenance cost is low, the multiway forging hydraulic press control device based on soft initiator of long service life.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is:
A multiway forging hydraulic press control device for soft initiator, is provided with soft initiator between the main pump motor of described multiway forging hydraulic press and power supply, and described soft initiator is electrically connected to described main pump motor by relay.
As preferred version, the utility model has also adopted following technical scheme:
Described soft initiator is ABB soft initiator PST142-600-70.
Described main pump motor comprises six 152KW motors and two 34.5KW motors.
Advantage and the good effect that the utlity model has are: the utility model is by arranging soft initiator between the main pump motor at multiway forging hydraulic press and power supply; utilize soft initiator to control overload impact electric current or overload voltage; thereby minimizing overload impact electric current or overload voltage work the mischief to the main pump motor of multiway forging hydraulic press; therefore effectively protected the safe operation of multiway forging hydraulic press; prevent trouble before it happens; reduce the maintenance cost of multiway forging hydraulic press simultaneously, extended the service life of multiway forging hydraulic press.
Accompanying drawing explanation
Fig. 1 is soft initiator circuit connection diagram of the present utility model;
Fig. 2 is electric motor starting circuit connection schematic diagram of the present utility model.
Wherein: 1, soft initiator; 2, contactor; 3, stop key; 4, start button.
The specific embodiment
For further understanding utility model content of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a multiway forging hydraulic press control device for soft initiator, comprising: the soft initiator 1 between the main pump motor that is arranged at multiway forging hydraulic press and power supply, contactor 2, for being connected relay K AP1, relay K AP2 and the relay K AP1 of main pump motor, wherein: the preferred ABB soft initiator PST142-600-70 of soft initiator 1, but be also not limited in the soft initiator of above-mentioned model, the power supply terminal POWER of soft initiator 1 is connected with alternating current 220V power supply, No. 16 of soft initiator 1, No. 19 terminal is connected with alternating current 220V power supply, in conjunction with Fig. 2, work as and press start button SB201, thereby contactor KM11 obtains the auxiliary contact KM11.1 closure of contactor KM11 in electric corresponding diagram 1 makes relay K AP3 obtain the electric relay auxiliary contact KAP3.1 closure that makes, No. 10 terminals (24V power positive end) other end that KAP3.1 mono-end is connected on soft initiator 1 is connected on No. 5 terminals of soft initiator (soft initiator start end), after KAP3.1 closure, soft initiator has started, No. 17 terminals of soft initiator 1 are connected with zero line by relay K AP1, relay K AP1 is soft initiator bypass start-up indicating relay, after the normal startup of soft start, it is the switch closure between No. 16 terminals and No. 17 terminals that soft initiator internal by-pass starts indicator cock, KAP1 obtains electric, bypass start-up completes, thereby in Fig. 2, auxiliary contact KAP1.1 is closed, it is electric that thereby contactor KM12 obtains, electric motor starting major loop has started, while contactor KM12 obtains electric auxiliary contact KM12.1 and has disconnected bypass start-up loop, soft starter for motor completes, No. 20 terminals of soft initiator 1 are connected with zero line by relay K AP2, relay K AP2 is soft initiator warning indicating relay, when soft initiator occurs when abnormal in start-up course, the closed KAP2 of soft initiator internal alarm switch (i.e. switch between No. 19 terminals and No. 20 terminals) obtains electric, soft starter is out of service.
Refer to Fig. 2, Fig. 2 is electric motor starting circuit connection schematic diagram of the present utility model, and the main pump motor of the multiway forging hydraulic press in this specific embodiment comprises six 152KW motors and two 34.5KW motors; 3 SB301 that stop key by two-way parallel connection that stop key form with the SB302 that stops key; Stop key SB301 through electrothermal relay FR1 by two-way connecting to neutral line, be wherein provided with on the way and start button SB201 and contactor KM11, an other road is provided with electric shock switch and contactor KM12; Stop key SB302 through electrothermal relay FR2 by two-way connecting to neutral line, be wherein provided with on the way and start button SB202 and contactor KM21, an other road is provided with electric shock switch and contactor KM22; So, starting button 4 forms by starting button SB201 and starting button SB202, above-mentioned electric motor starting loop can connect four simultaneously, and therefore in actual use, the multiway forging hydraulic press in this specific embodiment needs two identical above-mentioned electric motor starting loops just can work.
Above a kind of embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
