Abstract
The invention discloses a punching detection device, which comprises an upper mould and a lower mould, wherein a punch is arranged on the upper mould; a groove is formed in a position, corresponding to the lower mould, of the punch; a passage is formed in the lower mould; and one end of the passage is communicated with the groove, and the other end is connected with a dust concentration sensor. The punching detection device has the characteristics that during the punching operation, the lower mould is fixed on a punching machine; the workpiece is positioned on the lower mould; the up-and-down motion of the upper mould drives the up-and-down motion of the punch to punch the workpiece; if the hole is got through, the scraps produced due to the punching fall into the groove and the passage, and the dust concentration sensor can detect that the dust concentration becomes higher; and if the hole is not got through, the dust concentration sensor cannot detect the change of the dust concentration.
Description
Technical field
The present invention relates to a kind of punching checkout gear, being used for detecting when punch press carries out punch operation punching has not success.
Background technology
Punch press production is mainly at sheet material.By mould, can make blanking, punching, moulding, pull and stretch, finishing, essence is dashed, 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 fractures easily when punching press, perhaps the drift situation that may cause punching not get through owing to reasons such as wearing and tearing.
Be the lead frame punching checkout gear of the patent disclosure of 102825102A as publication number, comprise a holder and a test rod, be disposed with coaxial small sircle hole and big hole mutually in the described holder from top to bottom, described test rod comprises from top to bottom spring lever, boss, feeler lever and the probe of mutual coaxial setting successively, 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.
Though 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 present invention is directed to the prior art deficiency, a kind of punching checkout gear is provided, whether this punching checkout gear can directly detect after punching and portal logically, does not need extra testing.
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, comprise upper die and lower die, described patrix is provided with drift, the position of the corresponding counterdie of described drift is provided with groove, described counterdie is provided with passage, and described passage one end is communicated with described groove, and the described passage other end is connected with sensor of dust concentration.Counterdie is fixed on the punch press when carrying out punch operation, workpiece is placed on the counterdie, patrix moves up and down and drives drift and move up and down and punch at workpiece, if the hole has been got through, the chip that punching produces on the workpiece can drop in groove and the passage, sensor of dust concentration can detect dust concentration and become big, and sensor of dust concentration can not detect the dust concentration variation if the hole is not got through so.
In the technique scheme, preferred, described passage is provided with fan, fan is set can prevents that detrital deposit from detecting the passage congestion affects in groove so that the dust that each punching produces can both blow out from passage.
The present invention compared with prior art, have following beneficial effect: the present invention's counterdie when carrying out punch operation is fixed on the punch press, workpiece is placed on the counterdie, patrix moves up and down and drives drift and move up and down and punch at workpiece, if the hole has been got through, the chip that punching produces on the workpiece can drop in groove and the passage, and sensor of dust concentration can detect dust concentration and become big, and sensor of dust concentration can not detect the dust concentration variation if the hole is not got through so.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the 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, comprise patrix 1 and counterdie 2, described patrix 1 is provided with drift 11, the position of described drift 11 corresponding counterdies 2 is provided with groove 21, described counterdie 2 is provided with passage 22, and described passage 22 1 ends are communicated with described groove 21, and described passage 22 other ends are connected with sensor of dust concentration 3.Described passage 22 is provided with fan 4, fan 4 is set can prevents that detrital deposit from detecting passage 22 congestion affects in groove 21 so that the dust that each punching produces can both blow out from passage 4.Counterdie 2 is fixed on the punch press when carrying out punching 11 operations, workpiece is placed on the counterdie 2, patrix 1 moves up and down and drives drift 11 and move up and down and punch at workpiece, if the hole has been got through, the chip that punching produces on the workpiece can drop in groove 21 and the passage 22, sensor of dust concentration 3 can detect dust concentration and become big, and sensor of dust concentration 3 can not detect the dust concentration variation if the hole is not got through so.
Claims (2)
1. punching checkout gear, comprise patrix (1) and counterdie (2), described patrix (1) is provided with drift (11), it is characterized in that: the position of the corresponding counterdie of described drift (11) (2) is provided with groove (21), described counterdie (2) is provided with passage (22), described passage (22) one ends are communicated with described groove (21), and described passage (22) other end is connected with sensor of dust concentration (3).
