Abstract
An electric device capable of preventing a mechanical press machine stroke fault comprises a stop button, a start button, a time relay delay contact, a contactor, a contactor normally open contact, an indicator light, a press machine stroke down contactor interlock, a press machine stroke return stroke contactor interlock, and a time relay. The stop button, the start button, the time relay delay contact and the contactor are sequentially in series connection, the contactor normally open contact and the start button are in parallel connection, and after being in series connection, the time relay delay contact and the contactor are in parallel connection with the indicator light, and therefore a first circuit is formed. The press machine stroke down contactor interlock, the press machine stroke return stroke contactor interlock and the time relay are sequentially in series connection to form a second circuit and then the second circuit is in parallel connection with the first circuit. By the adoption of the electric device, a mechanical press machine can be protected after the stroke is out of control caused by circuit breakdown during the running process, and the fault phenomenon caused by electric device breakdown is effectively prevented.
Description
Technical field
The utility model belongs to mechanical pressure machinery field, relates to a kind of punching machine stroke that prevents and connects the electrical installation of car.
Background technology
The safety prevention measure of punching machine is the effective guarantee of guaranteeing device security, and the both hands button is widely used in production and the application of forcing press as effective safeguard procedures of forcing press, has effectively protected operative employee's personal safety.The both hands button is to be installed with standby a kind of safe operating device for punching, comprise three buttons, the centre is scram button, play the effect of emergent stopping lathe, both sides are action button, must both hands press just simultaneously to work any hand release button in the descending process of press ram, slide block namely can be out of service, thereby ensure operative employee's personal safety.The in recent years application of photoelectric protector has enlarged the zone of protection of forcing press especially, has formed double protection with the both hands button, has guaranteed that effectively anyone or object enter working region equipment all with out of service.But equipment is in operation and also can occurs because the equipment that electric fault causes connects car phenomenon (relay that causes controlling stroke owing to apparatus failure is in attracting state, and slide block is in operation out of control).Connecting car is a kind of serious equipment fault, and Lian Chehou, the lighter can cause part to be damaged by pressure, and severe one can cause the mould accident or directly cause personal injury, has very large potential safety hazard.
The utility model content
The purpose of this utility model is that a kind of punching machine stroke that prevents of design connects the electrical installation of car, take electrical control as starting point, and the design runlength control circuit, thus prevent company's car phenomenon of being caused by apparatus failure.
The technical solution of the utility model is: prevent that the punching machine stroke from connecting the electrical installation of car, comprising: stop button, start button, time relay delayed contact, contactor, contactor normally opened contact, indicator lamp, the descending contactor interlocking of the stroke of a press, stroke of a press backhaul contactor interlocking, the time relay.It is characterized in that: stop button, start button, time relay delayed contact, contactor are connected in series successively, contactor normally opened contact and start button are connected in parallel, time relay delayed contact, contactor are connected in series rear and indicator lamp is connected in parallel, and form the first loop; After the descending contactor interlocking of the stroke of a press, stroke of a press backhaul contactor interlocking, the time relay are connected in series successively and form second servo loop, be connected in parallel with the first loop again.
The utility model can reach following beneficial effect after adopting technique scheme: after adopting this device; can make punching machine stroke in running play defencive function because of fault after out of control; effectively prevented company's car phenomenon of being caused by apparatus failure; ensured the safety of operative employee and mould; respond well through practice, reach control and caused the purpose that connects the car phenomenon by apparatus failure.
Description of drawings
Fig. 1 is that the utility model prevents that punching machine from preventing that stroke from connecting the circuit diagram of car electrical installation;
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.As shown in the figure, prevent that the punching machine stroke from connecting the electrical installation of car, comprising: stop button 1, start button 2, time relay delayed contact 3, contactor 4, contactor normally opened contact 5, indicator lamp 6, the descending contactor interlocking 7 of the stroke of a press, stroke of a press backhaul contactor interlocking 8, the time relay 9.Stop button 1, start button 2, time relay delayed contact 3, contactor 4 are connected in series successively, contactor normally opened contact 5 is connected in parallel with start button 2, time relay delayed contact 3, contactor 4 are connected in series rear and indicator lamp 6 is connected in parallel, and form the first loop; After the descending contactor interlocking 7 of the stroke of a press, stroke of a press backhaul contactor interlocking 8, the time relay 9 are connected in series successively and form second servo loop, be connected in parallel with the first loop again.
When stop button 1 is in closure state; before the control power supply, install a contactor 4 with zero voltage protection additional; contactor 4 is by the time relay 9 controls; the time relay 9 is by the descending contactor interlocking 7 of the stroke of a press and 8 controls of stroke of a press backhaul contactor interlocking; after start button 2 starts; indicator lamp 6 is bright; contactor 4 self-lockings operation; when the descending contactor of stroke of a press interlocking 7 and stroke of a press backhaul contactor are interlocked 8 adhesives when surpassing 1.3 journey times; the time relay 9 sends signal so that time relay delayed contact 3 disconnects; thereby so that contactor 4 disconnects; because the normally opened contact of contactor 4 is interlocked in lathe master control power supply; institute is so that forcing press total control circuit dead electricity, and forcing press is out of service, connects the car phenomenon and can not occur thereby just protect this type of.
The utility model is simple in structure, transformation is simple and easy, can install improvement additional at former forcing press circuit; and can promote; can and use enterprise to punching machine production a kind of very effective anti-car method that connects is provided; not only effectively ensure intact in punching course of mould and part, protected especially operative employee's personal safety.
