Description
Technical field
The present invention relates to a kind of checkout gear, particularly relate to a kind of progressive die punching press checkout gear, belong to diel product technical field.
Background technology
At present, step pitch detects is method common in continuous mould.The position mainly sent into by detecting material strip judges whether mould can Progressive symmetric erythrokeratodermia further work.But traditional detection method accuracy of detection is lower; the time that uncontrollable mould is shut down, when there is misdelivery material can not 100% anti-stopping materials strip send wrong position and the burn failure that causes, to there is precision low apart from detecting for existing cloth; die life is short, and safeguards the defects such as frequent.
Summary of the invention
The object of the present invention is to provide a kind of structure simple, with low cost, willing workpiece feeding detection device by mistake during misdelivery material.
Described workpiece is feeding detection device by mistake, for carrying out feeding detection to a conductive material, comprise optoelectronic switch and relay, a mounting bracket, described mounting bracket is provided with detecting element, described detecting element comprises a housing, probe is provided with in described housing, the top of probe arranges back-moving spring, described probe and described optoelectronic switch, relay is electrically connected, optoelectronic switch is electrically connected with a PLC by a data wire, described conductive material is arranged on below detecting element, described guided missile material arranges conductive through holes, conductive through holes has a madial wall, described probe has the probe of the bottom that is positioned at, probe can move down and stretch in conductive through holes, the probe of described probe does not contact with the madial wall of conductive through holes when being positioned at described conductive through holes.
The upper end of described housing arranges screw thread, and housing upper end covers plug screw, and one end of described data wire is electrically connected with probe through described plug screw.
Also arrange a guide plate below described mounting bracket, through described guide plate below described housing, described conductive material moves up and down, and conductive through holes and probe do not promote probe moves to timing conductive material.
Beneficial effect of the present invention is: when utilizing described probe to contact with conductive material, forms path, photosignal is sent to PLC; control described mould to shut down; the misdelivery material that workpiece is carried out in the design combined with probe by conductive through holes detects, and structure is simple, with low cost.
Accompanying drawing explanation
Accompanying drawing 1 is the structural scheme of mechanism that workpiece of the present invention misses feeding detection device.
Detailed description of the invention
Accompanying drawings 1 is depicted as described workpiece of the present invention feeding detection device by mistake, for carrying out feeding detection to a conductive material 8, comprise optoelectronic switch 1 and relay (not shown), a mounting bracket 3, described mounting bracket 3 is provided with detecting element 4, described detecting element 4 comprises a housing 5, probe 6 is provided with in described housing 5, the top of probe 6 arranges back-moving spring 7, described probe 6 and described optoelectronic switch 1, relay is electrically connected, optoelectronic switch 1 is electrically connected with a PLC 15 by a data wire 14, described conductive material 8 is arranged on below detecting element 4, described guided missile material 8 arranges conductive through holes 9, conductive through holes 9 has a madial wall 10, described probe 6 has the probe 11 of the bottom that is positioned at, probe 6 can move down and stretch in conductive through holes 9, the probe 11 of described probe 6 does not contact with the madial wall 10 of conductive through holes 9 when being positioned at described conductive through holes 9.The upper end of described housing 5 arranges screw thread 12, and housing 5 upper end covers plug screw 13, and one end of described data wire 14 is electrically connected with probe 6 through described plug screw 13.
Also arrange a guide plate 16 below described mounting bracket 3, through described guide plate 16 below described housing 5, described conductive material 8 moves up and down, and conductive through holes 9 and probe 6 do not promote probe 6 moves to timing conductive material 8.
Described relay 2 is normal closing type relay, when described conductive material 8 (in the present embodiment, described conductive material is mould steel) when sending part, position is not to timing, and conductive material 8 contacts with probe 6, now probe 6 and conductive material 8 are formed and are energized, circuit turn-on, relay 2 disconnects, simultaneously, infrared laser signal is sent to PLC 15 by optoelectronic switch 1, can automatically control punch press and quit work.
When utilizing described probe to contact with conductive material; form path; photosignal is sent to PLC, controls described mould and shut down, misdeliver with other and expect compared with detection part; the structure of checkout gear and installing hole are processed simpler; can reduce holistic cost, can make a response immediately when contact contacts with conductive material timely, the misdelivery material that workpiece is carried out in the design combined with probe by conductive through holes detects; structure is simple, with low cost.
