The utility model has the following benefits: the device can monitor the air pressure inside the compressed air inlet pipe of the pneumatic press-connection machine, and can remind operators of inadequate air pressure, so that operators can immediately take remedial measures, lest the products fall short of the standard. The device is simple in structure and low in cost, and is very convenient to operate and easy to implement in the actual production process.
Description
Technical field
The utility model relates to a kind of low-pressure alarming device, relates in particular to pneumatic press-connection machine.
Background technology
Pneumatic press-connection machine is with the crimping apparatus of pressurized air as power, can be used for the assembling of wire harness two ends upper terminal.
In actual applications, normally provide pressurized air simultaneously to many pneumatic press-connection machines by an air compressor machine, pressurized air gas transmission main of configuration on the output terminal on the air compressor machine, the pressurized air gas transmission main is communicated with many pneumatic press-connection machines by many compressed air inlet pipes.In general, the compressed air pressure that pneumatic press-connection machine needs should be not less than the crimp quality that 0.45Mpa could guarantee terminal, and for this reason, the compression pressure scope of air compressor output is controlled at 0.7～1Mpa usually.
Under the situation of operate as normal, because the compressed air pressure of air compressor machine output is much larger than pneumatic press-connection machine desired compression air pressure, therefore generally can satisfy the crimping requirement of pneumatic press-connection machine, but, under some special situation, just start soon as air compressor, pressure does not also reach more than the 0.45Mpa; Perhaps, many press-connection machines are worked in a flash simultaneously at certain, and at this moment the input air pressure of press-connection machine can will descend, can fall to below the 0.45Mpa when serious, thereby make crimping pressure can not reach 0.45Mpa, cause the terminal crimp strength to descend, the product of producing is defective.
For second kind of situation, adopt technological means such as increasing air compressor gas-storing capacity and amplification input pneumatic press pipe diameter can avoid taking place, but this mode to drop into more fund, unsatisfactory from production cost.
When above two kinds of situations take place, in time informing the operative employee on each pneumatic press, and carry out its corresponding measures, it is necessary designing a kind of low-pressure alarming device simple in structure, lower-cost.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of cost lower, simple in structure, the low-pressure alarming device that can in time point out when the compressed air inlet pipe internal gas pressure deficiency of pneumatic press-connection machine.
The utility model is achieved through the following technical solutions:
A kind of low-pressure alarming device of pneumatic press-connection machine is characterized in that:
Pressure transducer of configuration on the compressed air inlet pipe tube wall of pneumatic press-connection machine, pressure transducer connects on-off element,
On-off element has two working positions, perhaps is electrically connected alarm lamp, alarm buzzer and external power supply, perhaps is electrically connected relay indicating light and external power supply.
The principle of work of this device is: when the compressed air inlet pipe internal gas pressure value of pneumatic press-connection machine during greater than setting value, on-off element is electrically connected relay indicating light and external power supply, and the operator judges thus can carry out the crimping assembling; When the detected compressed air inlet pipe internal gas pressure of pressure transducer value is lower than setting value; will the displacement of pull switch element; be electrically connected alarm lamp, alarm buzzer and external power supply; send alerting signal; to remind the operator in time to shut down to avoid follow-up crimping product defective; the operator opens press-connection machine again after waiting for a time period, the product of crimping in time carries out ftercompction during to warning, and then carries out follow-up crimping.
Consider in the crimping process of Wiring harness terminal, crimping pressure can guarantee crimp quality preferably more than or equal to 0.45Mpa, therefore setting value is generally got 0.45Mpa, and promptly the variation critical value of on-off element working position is that the detected air pressure value of pressure transducer is less than 0.45Mpa.
Further, pressure transducer can adopt elastic spring, when being lower than setting value by measuring pressure, the free end of elastic spring will produce displacement, directly or after relatively promote on-off element, change the on off operating mode of on-off element, reach the purpose that prompting is reported to the police.
Further again, consider and to have only one or several pneumatic press-connection machine work under some situation that this moment is as long as after noticing waiting for that air compressor machine starts a period of time, operate press-connection machine again, basically just can avoid the problem of crimping insufficient pressure, not need warning function substantially.Therefore can between on-off element and external power supply, be provided with power switch.When not needing to use warning device, directly the powered-down switch gets final product.
The beneficial effects of the utility model are:
1, can monitor the compressed air inlet pipe internal gas pressure of pneumatic press-connection machine, timely prompting operation person in time remedies when air pressure is not enough, avoids the generation of substandard product;
2, the device simple in structure, cost is lower, the utilization in actual production is very convenient, is beneficial to enforcement.
