Description
Technical field
The utility model is related to a kind of detection means for punch press.
Background technology
Punch press is exactly a punching type forcing press.In national product, for Sheet Metal Forming Technology than tradition machinery due to processing
Have saving material and the energy, efficiency high, it is not high to operator's technical requirements and by various mould applications can make machinery plus
Work is beyond one's reach product these advantages, thus its purposes is more and more extensive.
Punching production is primarily directed to sheet material.By mould, blanking, punching, shaping, drawing, finishing, essence can be made
Punching, shaping, riveting and extrusion etc. are widely used in electronics, communication, computer, household electrical appliance, furniture, the vehicles, (vapour
Car, motorcycle, bicycle) punching press and the shaping such as hardware parts.
Because the feed mechanism precision of existing punch press is inadequate, feed length is unstable, has duration sometimes short；On the other hand,
Extraneous factor, such as air pressure are unstable, material deforms in itself or circuit electromagnetic touch is bad, will also result in feeding dislocation；This
Outward, produced in the cutting die of punch press and jump material, also result in feeding skew.
Material strip feeding position once there is deviation, cutting die will be caused precisely to cut, product defective products rate compared with
It is high.
Utility model content
The purpose of this utility model is to provide a kind of detection means for punch press.
According to one side of the present utility model, there is provided a kind of detection means for punch press, including：
Detection unit, located at the discharge outlet of punch press, by the material strip of the discharging opening of punch press by detection unit, detection is single
Unit includes multiple detection probes, and located at material strip outside, and towards material strip, material strip has hole to detection probe, and detector is used to examine
Survey whether corresponding position material strip is hole, so be given one 0 or 1 switching signal；
Comparing unit, the input of comparing unit is connected respectively with detector, for opening of comparing that multiple detectors provide
OFF signal, and a comparison signal is provided according to result of the comparison；
Main control unit, the input of main control unit is connected with the output end of comparing unit, for receive comparing unit to
The comparison signal for going out, and export the corresponding control instruction set in advance of different comparison signals.
In some embodiments, detection unit includes two detection probes,
In some embodiments, detection probe is correlation type detection probe or reflection-type detection probe.
In some embodiments, detection probe is fiber sensor or shade camera.
In some embodiments, the output end of main control unit is also associated with warning device and arresting gear.
Using the detection means for punch press of above technical scheme, acted not only as inside punch press by detection probe
Effective auxiliary of CCD detection and localizations, panorama detection is carried out to material strip, material strip is positioned more precisely, so that it is bad to reduce product
Product rate；But also can in time find the defective products that punch press is produced, and and alarm and shutdown, and then be easy to sorting to process, keep away
Exempt from defective products outflow.
Brief description of the drawings
Fig. 1 is a kind of schematic diagram of the detection means for punch press of implementation method of the utility model.
Fig. 2 is the structural representation of detection unit shown in Fig. 1.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 and Fig. 2 schematically show the detection dress for punch press according to a kind of implementation method of the present utility model
Put.
According to one side of the present utility model, there is provided a kind of detection means for punch press.As illustrated, the device
Including：Detection unit 1, comparing unit 4 and main control unit 5.
Wherein, detection unit 1 is on a support 3.
Discharge outlet of the support 3 located at punch press.
By the material strip 2 of the discharging opening of punch press by support 3.
Detection unit 1 includes two detection probes (1a, 1b).
Two detection probes (1a, 1b) are fixed on the support 3 in the outside of material strip 2, and towards material strip 2.
Material strip 2 has hole, and two detection probes (1a, 1b) are used to detect whether corresponding position material strip 2 is hole,
And then each provide a naAnd nb。naAnd nbRespectively 0 or 1 switching signal.
Two detection probes (1a, 1b) are fiber sensor, unglazed if corresponding position is the hole of material strip 2
To inductor, now fiber sensor provides the switching signal that is 0 to line reflection, whereas if corresponding position is material strip 2
There is no the part of hole, then there is light to reflex to inductor, now fiber sensor provides the switching signal that is 1.
The input of comparing unit 4 and two detection probes (1a, 1b) connect respectively, for comparing naAnd nb, and according to than
Compared with result provide a comparison signal.
The input of main control unit 5 is connected with the output end of comparing unit 4, for receiving the ratio that comparing unit 4 is provided
Compared with signal, and export the corresponding control instruction set in advance of different comparison signals.
For different material strips, if the position of the hole being distributed thereon differs, naAnd nbSwitching signal to
It is not necessarily identical, can be by n under normal circumstancesaAnd nbNumerical value as normal value, other naAnd nbNumerical value as exception
Value.
Control instruction is corresponding with exceptional value, and when there is exceptional value, main control unit 5 sends control instruction.
The output end of main control unit 5 is also associated with warning device 6 and arresting gear 7.
When main control unit 5 judges that material strip 2 is in abnormality according to comparison signal, punch press is stopped by arresting gear 7
Work, and alarm is sent by warning device 6, until abnormality is excluded.
Two detection probes (1a, 1b) are fiber sensor
In other examples, detection probe can also be shade camera.
In some other embodiments, detection probe can also be other correlation type detection probes or reflection-type inspection
Probing head.
Using the detection means for punch press of above technical scheme, acted not only as inside punch press by detection probe
Effective auxiliary of CCD detection and localizations, panorama detection is carried out to material strip, material strip is positioned more precisely, so that it is bad to reduce product
Product rate；But also can in time find the defective products that punch press is produced, and and alarm and shutdown, and then be easy to sorting to process, keep away
Exempt from defective products outflow.
Above-described is only some implementation methods of the present utility model.For the person of ordinary skill of the art,
On the premise of the utility model creation design is not departed from, various modifications and improvements can be made, these belong to this practicality
New protection domain.
