Abstract
The invention discloses a punched hole detecting device of a punching machine. The punched hole detecting device comprises an upper mold and a lower mold, wherein a punch is arranged on the upper mold; a groove is formed in the punch opposite to the lower mold; a first elastic piece is vertically arranged in the groove, and is provided with a conductive contact; a first elastic contactor and a second elastic contactor are arranged below the conductive contact; the first elastic contactor is connected with a relay; the relay is connected with the positive pole of a first power supply; the second elastic contactor is connected with the negative pole of the first power supply; the relay is connected with a second power supply and an alarming device; and when the relay is electrified, the alarming device is cut off. The punched hole detecting device can timely detect if a hole is through after the hole is punched, so that the unnecessary rework can be prevented due to no punching through of a plate body.
Description
Technical field
The present invention relates to a kind of punching checkout gear of punch press, while carrying out punch operation for punch press, detecting punching has not success.
Background technology
Punch press is produced mainly for sheet material.By mould, can make blanking, punching, moulding, pull and stretch, finishing, essence punching, shaping, riveted joint and extrusion etc., be widely used in every field.When the tiny hole of punching press, because the drift of stamping die is thinner, when punching press, drift easily fractures, or the situation that drift may cause punching not get through due to reasons such as wearing and tearing, and the present general automatic feeding friction feeding that adopts in plate body punch process, whether workman's peep hole of cannot popping one's head in is got through, and could find after therefore need to processing a period of time, not only to change drift but also the plate body that punching is not worn originally will be processed again, wasting time very much.
Summary of the invention
The present invention is directed to prior art deficiency, a kind of punching checkout gear of punch press is provided, whether this punching checkout gear can detect and portal logically in time after punching, prevents that plate body from not getting through and carry out unnecessary doing over again.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of punching checkout gear of punch press, comprise upper die and lower die, on described patrix, be provided with drift, the position of the corresponding counterdie of described drift is provided with groove, in described groove, be provided with the first upright elastic component, on described the first elastic component, be provided with conductive contact blade, described conductive contact blade below is provided with the first spring contact, the second spring contact, described the first spring contact is connected with relay, described relay connects the first positive source, described the second spring contact connects described the first power cathode, described relay is connected with second source and warning device, after described relay power, described warning device power-off.This punching checkout gear impacts to be pressed down on conductive contact blade by drift conductive contact blade is contacted with the second spring contact with the first spring contact, make relay power, after relay power, make the connection between second source and warning device disconnect, after rising, drift also can attract a period of time according to the electromagnet in Lenz's law relay, by changing this time period of parameter adjustment of the coil in relay, be greater than drift and be flushed to the time in groove next time, relay just makes warning device and second source in off-state all the time like this, warning device just can not reported to the police, if drift interrupts, electromagnet in relay stops attracting iron core so, thereby warning device and second source are connected, warning device is just reported to the police, whether logically adopt this punching checkout gear after punching, to detect in time to portal, prevent plate body from not getting through and carry out unnecessary doing over again.
In technique scheme, preferred, between described warning device and described second source, be provided with switch.Switch is set to be made will between warning device and second source, not disconnect when punch press is worked.
The present invention compared with prior art, there is following beneficial effect: this punching checkout gear of the present invention impacts to be pressed down by drift conductive contact blade is contacted with the second spring contact with the first spring contact on conductive contact blade, make relay power, after relay power, make the connection between second source and warning device disconnect, after rising, drift also can attract a period of time according to the electromagnet in Lenz's law relay, by changing this time period of parameter adjustment of the coil in relay, be greater than drift and be flushed to the time in groove next time, relay just makes warning device and second source in off-state all the time like this, warning device just can not reported to the police, if drift interrupts, electromagnet in relay stops attracting iron core so, thereby warning device and second source are connected, warning device is just reported to the police, whether logically adopt this punching checkout gear after punching, to detect in time to portal, prevent plate body from not getting through and carry out unnecessary doing over again.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the present invention is described in further detail: referring to Fig. 1, a kind of punching checkout gear of punch press, comprise patrix 1 and counterdie 2, on described patrix 1, be provided with drift 11, the position of the corresponding counterdie 2 of described drift 11 is provided with groove 21, in described groove 21, be provided with the first upright elastic component 3, on described the first elastic component 3, be provided with conductive contact blade 4, described conductive contact blade 4 belows are provided with the first spring contact 5, the second spring contact 6, described the first spring contact 5 is connected with relay 7, described relay 7 connects the first power supply 8 positive poles, described the second spring contact 6 connects described the first power supply 8 negative poles, described relay 7 is connected with second source 9 and warning device 10, after described relay 7 energisings, described warning device 10 power-off.Warning device 10 can be indicator lamp or buzzer etc., this punching checkout gear impacts to be pressed down on conductive contact blade 4 by drift conductive contact blade 4 is contacted with the second spring contact 6 with the first spring contact 5, make relay 7 energisings, after relay 7 energisings, the connection between second source 9 and warning device 10 is disconnected, after rising, drift also can attract a period of time according to the electromagnet in Lenz's law relay 7, by changing this time period of parameter adjustment of the coil in relay 7, be greater than drift and be flushed to the time in groove 21 next time, relay 7 just makes warning device 10 and second source 9 in off-state all the time like this, warning device 10 just can not reported to the police, if drift interrupts, electromagnet in relay 7 stops attracting iron core so, thereby warning device 10 and second source 9 are connected, warning device 10 is just reported to the police, whether logically adopt this punching checkout gear after punching, to detect in time to portal, prevent plate body from not getting through and carry out unnecessary doing over again.
Between described warning device 10 and described second source 9, be provided with switch 12, switch 12 be set and make will between warning device 10 and second source 9, not disconnect when punch press is worked.
