The protecting device comprises a controller which is connected with a punch driving motor and further comprises a detecting switch and an alarm lamp which are connected with the controller, wherein the detecting switch is fixedly connected with the top end of a frame of a machine tool, which is corresponding to the motion path of a crank and a connecting bar, and a processor which records signals of the stopping positions of the crank and the connecting bar, which are detected by the detecting switch, and correspondingly sends out the corresponding signals of the right position, single no-parking position signals, single overshooting position signals and detects the abnormal signal alarming process is arranged in the controller. The utility model has high automation degree, accurate detection results, strong fault judgment function, and the reliability and the security are greatly improved.

Description

Punch press two spends protective gear

Technical field

The utility model relates to a kind of protective equipment of punch press, relates in particular to a kind ofly preventing that the device towards phenomenon from appearring connecting in lathe under the single operating mode.

Background technique

In the certain operations occasion, need punch press to finish processing, for example with single punching press form, in some dischargings, put on the cumbersome combined mould of material, need the blank placement positioning is accurate, operate the lathe action again, then, discharging is put material at last again and is carried out next part processing.At this moment, need to guarantee punch press with the work of single pattern, prevent its connect dash or slide block two degree of saying so fall, avoid defective work piece, mould, also avoid occurring simultaneously injury accident.

State Intellectual Property Office's application number is the patented technology that " 90212356.4 ", " 200420027403.7 " name are called " the anti-flushing device that connects of press machine ", " punching machine safety device ", discloses respectively two kinds of anti-companies to dash the device that in other words conj.or perhaps anti-limited slip block two degree fall.The former technological scheme is " to adorn an auxiliary cam on the camshaft of manipulator, before auxiliary cam is fixed on main cam, should spend working key tail band one oblique angle less than 45 with the angle of main cam." under normal circumstances, it finishes one-shot by main cam; When electrical failure or workman's misoperation, auxiliary cam blocks the key tail, and the company of preventing dashes.The latter's technological scheme mainly is the pushing handle mechanisms that is provided with on operating table with the slide block interlock.Both all belong to the mechanical type protective gear, and the former can play the effect that prevents that lathe slide block two degree from falling, and the latter can prevent that operator's arm from entering stamped area in slide block whereabouts mistiming.But both complicated integral structure when playing aforementioned effect, can not accurately be judged the fault state of punch press, and maintenance is complicated.

The model utility content

The utility model provides a kind of lathe that can prevent to occur connecting under the single operating mode towards phenomenon, and the state of equipment unit can detect fault the time, punch press two degree that the have self-checking function simultaneously protective gear that falls.

The technical solution of the utility model is: comprise the controller that connects the punch press drive motor, it also comprises a detecting switch that links to each other with controller, warning light, detecting switch is fixedly connected on the top of lathe frame, the position of corresponding bent axle, link motion track is established in the controller to record according to the stop position signal correspondence of the detected bent axle of detecting switch, connecting rod and is sent the processor that corresponding tram signal, single do not have parking spot signal, single overshoot position signal, detecting switch abnormal signal alert program.

Described detecting switch is near switch or optoelectronic switch.

Be provided with the detection induction point on bent axle, connecting rod, detecting induction point is projection or photoelectricity sheet.

It comprises that also one is arranged on the cam place sensitive switch corresponding with detecting switch of bent axle, and sensitive switch connects controller.

The utility model has changed in the past the mechanical type two degree safeguard structure that falls, come the running state of perception bent axle, connecting rod with electrical signal, correct, the error condition of judgment device operation, the processor that is provided with in controller has been put down in writing the signal comparison program of multiple error condition, can pick out multiple error condition.Meet the error condition signal, out of service by controller instruction punch press drive motor, avoid lathe under the single operating mode, to occur company towards phenomenon, and the state of equipment unit can detect fault the time, rest on which position as bent axle, connecting rod.Also have self-checking function simultaneously, when detecting switch breaks down, also can send warning signal, realize stopping.The utility model automaticity height, testing result is accurate, and fault judgement is powerful, and reliability, Security increase substantially.

Embodiment

As Fig. 1, the utility model comprises the controller that connects the punch press drive motor, it also comprises a detecting switch that links to each other with controller 1, warning light, detecting switch 1 is fixedly connected on the top of lathe frame 4, be positioned at upper dead center 2 places, and the position of corresponding bent axle, link motion track 5 is established in the controller to record according to the stop position signal correspondence of detecting switch 1 detected bent axle, connecting rod and is sent the processor that corresponding tram signal, single do not have parking spot signal, single overshoot position signal, detecting switch abnormal signal alert program.

Detecting switch 1 can be selected for use near switch or optoelectronic switch.

Be provided with on bent axle, connecting rod and detect induction point 3, detecting induction point 3 is projection or photoelectricity sheet.

It also comprises the sensitive switch that a cam place that is arranged on bent axle and detecting switch 1 are corresponding, and sensitive switch connects controller.

Of the present utility model is to be used for detecting the action signal that two degree fall near switch 1, two degree dropping control devices are installed on the bent axle top of lathe, as damaging near switch 1, and the ignorant words of operator, just can't detect two degree falls to moving, so safety for the operator, the utility model detects mutually with the sensitive switch of cam and near switch 1 again judges the good and bad of approaching switch 1, represent by upper dead center 2 tutorial light and running ready lamp, this is the chain reaction on the circuit, also be the safety for the operator, well-designed forming represented with the tutorial light flashing mode.During operating punch machine, positive and negative 30 degree are not when stopping in upper dead center 2 positions when slide block, and urgent stopping light is bright.Whether this system divides three kinds of situations to detect lathe respectively normal:

(1) single does not have parking, and when the lathe stop angle was spent above 60, the upper dead center lamp is flicker in 0.2 second at interval, and lamp is for dodging slowly, and the running ready lamp goes out, as Fig. 3.

(2) single overshoot, lathe stop angle surpass 30 degree, and the upper dead center lamp is flicker in 0.1 second at interval, and lamp is a quickflashing, and the running ready lamp goes out, as Fig. 4.

(3) the two degree detecting switch that falls is unusual, detecting switch 1 no signal can occur, as Fig. 5; Perhaps detecting switch 1 is in long logical state, as Fig. 6.Lathe stops at upper dead center 2 position upper dead center lamps and goes out, and the running ready lamp goes out.

Any situation in these three kinds of situations occurs, and stopping in emergency all appears in lathe, prevents that connecting towards phenomenon from appearring in the single running in lathe.

The time sequence status of the normal operation of the utility model lathe such as Fig. 2.
