Abstract
The invention discloses a punch protective device, comprising a foot switch, a punch circuit, a processing module, a first intermediate relay, a second intermediate relay, an infrared imager, a safety indicator light and a warning indicator light. The foot switch is stepped to start the infrared imager for work; the infrared imager detects whether a human body is in a protected area or not; a detection signal is transmitted to the processing module; if the human body is in the protected area, the processing module gives an instruction to the second intermediate relay so as to close the normally open contact of the second intermediate relay, and the warning indicator light is turned on; if no human body is in the protected area, the processing module gives an instruction to the first intermediate module, the normally open contact of the first intermediate relay is closed, the safety indicator light is turned on and the punch circuit is connected; when the foot switch is stepped again, the punch works normally. When a worker operates the punch improperly, the punch protective device disclosed by the invention can give a warning timely and prevent the punch from running continuously, so that operators are not injured.
Description
Technical field
The present invention relates to punching apparatus, relate in particular to the punch press protector, belong to the machining equipment technical field.
Background technology
Punch press is a kind of machining equipment commonly used of industrial enterprise; In the process of using punch press to produce, it is not strong inevitably can to run into safety of workers consciousness, even situation about operating against regulations; Thereby cause workman's person to come to harm, serious security incident occurs.Therefore, on punch press, set up safety device, when workman's misoperation, protector can in time give a warning, and stops punch press to continue operation, has crucial meaning to avoid operating personnel to come to harm.
Summary of the invention
The object of the present invention is to provide a kind of punch press protector, when workman's misoperation, protector can in time give a warning, and stops punch press to continue operation, comes to harm to avoid operating personnel.
the object of the invention is achieved through following technical scheme:
A kind of punch press protector comprises floor push 8, punch press operating circuit 12, also comprises processing module 2, first auxiliary reclay 3, second auxiliary reclay 4, infrared thermoviewer 5, green indicating lamp 9 and warning indicator lamp 10.Said floor push 8 links to each other with infrared thermoviewer 5, steps on floor push 8 and starts infrared thermoviewer 5 work, and said infrared thermoviewer has or not human body in the 5 detection protection zones; Detection signal flows to processing module 2, and processing module 2 links to each other with first auxiliary reclay 3, second auxiliary reclay 4, if detect human body is arranged in the protection zone; Processing module 2 sends instructions closed to second auxiliary reclay, 4, the second auxiliary reclays, 4 normally opened contacts, connects warning indicator lamp 10; If detecting does not have human body in the protection zone, processing module 2 sends instructions and links to each other with punch press operating circuit 12, green indicating lamp 9 respectively to first auxiliary reclay, 3, the first auxiliary reclays 3; First auxiliary reclay, 3 normally opened contacts are closed; Connect green indicating lamp 9 and punch press operating circuit 12, when stepping on floor push 8 once more, the punch press operate as normal.
The object of the invention can also further realize through following technical measures:
Aforementioned punch press protector also comprises the fixedly trailing arm support 6 of infrared thermoviewer 5, has one to regulate adjusting bolt 7 highly on the said trailing arm support 6.
Compared with prior art, the invention has the beneficial effects as follows: can detect and have or not human body in the zone of protection, when operating personnel's misoperation got into zone of protection, protector can in time give a warning, and stoped punch press to continue operation, came to harm to avoid operating personnel.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a circuit structure diagram of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is described further.
As shown in Figure 1, trailing arm support 6 is positioned on the punch press body 11, and infrared thermoviewer 5 is installed on the trailing arm support 6, has one to regulate adjusting bolt 7 highly on the said trailing arm support 6, can adjust the search coverage of infrared thermoviewer 5 easily.The off-limits zone of human body when the search coverage of said infrared thermoviewer 5 should be operate as normal.As shown in Figure 2, the punch press protector comprises floor push 8, punch press operating circuit 12, also comprises processing module 2, first auxiliary reclay 3, second auxiliary reclay 4, infrared thermoviewer 5, green indicating lamp 9 and warning indicator lamp 10.Said floor push 8 links to each other with infrared thermoviewer 5, steps on floor push 8 and starts infrared thermoviewer 5 work, and said infrared thermoviewer has or not human body in the 5 detection protection zones; Detection signal flows to processing module 2, and processing module 2 links to each other with first auxiliary reclay 3, second auxiliary reclay 4, if detect human body is arranged in the protection zone; Processing module 2 sends instructions closed to second auxiliary reclay, 4, the second auxiliary reclays, 4 normally opened contacts, connects warning indicator lamp 10; Owing to punch press operating circuit 12 access failures this moment; Step on floor push 8, punch press also can't be worked, and has guaranteed workman's safety.There is not human body in the protection zone if detect; Processing module 2 sends instructions to first auxiliary reclay 3; First auxiliary reclay 3 links to each other with punch press operating circuit 12, green indicating lamp 9 respectively, and first auxiliary reclay, 3 normally opened contacts are closed, connects green indicating lamp 9 and punch press operating circuit 12; When stepping on floor push 8 once more, the punch press operate as normal.Said processing module 2, first auxiliary reclay 3, second auxiliary reclay 4 are installed in the control cabinet 1.
Except that the foregoing description, the present invention can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of requirement of the present invention.
