Abstract
The utility model discloses a stamping die which comprises an upper die and a lower die. A punch is arranged on the upper die, a groove is formed in the portion, corresponding to the lower die, of the punch, a first insulating layer is arranged on the side wall of the groove, conducting liquid is filled in the groove, a channel communicated with the groove is formed in the lower die, a wire provided with a second insulating layer on the outer side is arranged in the channel, the wire is connected with a detection device, and the detection device is connected with the punch. When the die-casting die is used, whether a hole is communicated is detected directly after punching, additional detection work is not needed, and the stamping die is also suitable for detection of non-conducting workpieces like plastic parts.
Description
Technical field
The utility model relates to a kind of diel, is used for being installed in carrying out punching operation on the punch press, especially for punching.
Background technology
Punch press production is mainly for sheet material.By mould, can make blanking, punching, moulding, pull and stretch, finishing, the essence punching, shaping, riveted joint and extrusion etc. are widely used in every field.When the tiny hole of punching press, because the drift of stamping die is thinner, drift easily fractures when punching press, perhaps the drift situation that may cause punching not get through owing to reasons such as wearing and tearing.
Be the disclosed lead frame punching of 102825102A checkout gear such as publication number, comprise a holder and a test rod, be disposed with from top to bottom mutually coaxial small sircle hole and big hole in the described holder, described test rod comprises from top to bottom spring lever, boss, feeler lever and the probe of successively mutual coaxial setting, the outer cover of spring lever is provided with spring, spring lever is arranged in the small sircle hole, boss is arranged in the big hole, the diameter of probe is less than the diameter that needs to detect the hole in the lead frame, the upper end connection cable of test rod, the cable connection detector.This device is arranged on checkout gear the top of lead frame in use, the punching of lead frame arrive this checkout gear under the time, this checkout gear moves down a bit of distance, this distance is not more than the length of probe, if punching is accurate, probe stretches in the punching so, because the diameter of probe is less than the diameter of punching, probe can not touch lead frame, detector can not receive Continuity signal, if this punching is obstructed, probe will touch lead frame so, detector will receive Continuity signal so, and this punching is just defective so.
Although it is respond well that above-mentioned this checkout gear detects, after punching, detect, extra work can be produced, and the detection of nonconducting workpiece such as plastics can not be applicable to.
Summary of the invention
The utility model is not enough for prior art, and a kind of diel is provided, and whether this stamping die prodigiosin direct-detection after punching portals logical, does not need extra testing.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of diel, comprise upper die and lower die, be provided with drift on the described patrix, the position of the corresponding counterdie of described drift is provided with groove, the sidewall of described groove is provided with the first insulating barrier, be provided with conducting liquid in the described groove, be provided with the passage that communicates with described groove in the described counterdie, being provided with arranged outside in the described passage has the wire of the second insulating barrier, described wire is connected with checkout gear, and described checkout gear connects described drift.If this die casting is the punching success when work, drift can extend in the conducting liquid, checkout gear receives Continuity signal like this, send the conducting cue, when punching is illogical, drift just can not extend in the conducting liquid, and checkout gear just can not receive Continuity signal like this, can not send the conducting cue.
In the technique scheme, described checkout gear comprises power supply and the lamp of series connection, and lamp is bright when drift is successfully got through the hole, and lamp does not work when successfully not getting through the hole.
In the technique scheme, described checkout gear comprises power supply, resistance and the diode of series connection, and diode is bright when drift is successfully got through the hole, and diode does not work when successfully not getting through the hole.
The utility model compared with prior art, has following beneficial effect: if the utility model punching success when work, drift can extend in the conducting liquid, checkout gear receives Continuity signal like this, send the conducting cue, when punching was illogical, drift just can not extend in the conducting liquid, checkout gear just can not receive Continuity signal like this, can not send the conducting cue.When this die casting uses after punching direct-detection whether logically portal, do not need extra testing, and be applicable to the detection of nonconducting workpiece such as working of plastics.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment one.
Fig. 2 is the structural representation of the utility model embodiment two.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the utility model is described in further detail: referring to Fig. 1, embodiment one, a kind of diel, comprise patrix 1 and counterdie 2, be provided with drift 11 on the described patrix 1, the position of described drift 11 corresponding counterdies 2 is provided with groove 21, the sidewall of described groove 21 is provided with the first insulating barrier 3, be provided with conducting liquid 4 in the described groove 21, be provided with the passage 22 that communicates with described groove 21 in the described counterdie 2, being provided with arranged outside in the described passage 22 has the wire 5 of the second insulating barrier 51, and described wire 5 is connected with checkout gear 6, and described checkout gear 6 connects described drift 11.In the present embodiment, described checkout gear 6 comprises power supply 61 and the lamp 62 of series connection.If this die casting is the punching success when work, drift 11 can extend in the conducting liquid 4, checkout gear 6 receives Continuity signal like this, lamp 62 is bright, when punching is illogical, drift 11 just can not extend in the conducting liquid 4, and checkout gear 6 just can not receive Continuity signal like this, and lamp 62 does not work.
Referring to Fig. 2, embodiment two, be that from the difference of embodiment one checkout gear is different, in the present embodiment, described checkout gear 6 comprises power supply 61, resistance 63 and the diode 64 of series connection, if this die casting is the punching success when work, drift 11 can extend in the conducting liquid 4, checkout gear 6 receives Continuity signal like this, diode 64 is bright, and when punching was illogical, drift 11 just can not extend in the conducting liquid 4, checkout gear 6 just can not receive Continuity signal like this, and diode 64 does not work.
Adopt above-mentioned die casting so that after punching direct-detection portal whether logically, do not need extra testing, and be applicable to the detection of nonconducting workpiece such as working of plastics.
