Abstract
The utility model relates to a feed control circuit of a metal marking machine, which comprises an automatic marking travel switch, an automatic ejection travel switch, a DC24V control power supply, a marking time relay, a marking relay, an ejection electromagnetic valve coil relay, a cylinder return time relay, a cylinder return electromagnetic valve relay, wherein the marking time relay, the marking relay, the ejection electromagnetic valve coil relay and the cylinder return electromagnetic valve relay are connected with each other in parallel in the loop of the DC24V power supply, the marking time relay is serially connected with the marking travel switch, the marking relay is serially connected with the ejection travel switch of a cylinder, the ejection electromagnetic valve coil relay is serially connected with the ejection travel switch and the normally closed switch of the cylinder return electromagnetic valve relay, the cylinder return time relay is connected with the ejection travel switch and the intermediate node of the cylinder return electromagnetic valve relay, and the cylinder return electromagnetic valve relay is serially connected with the contact switch of the cylinder return time relay. Since the control switch can ensure that the working of the marking machine and the ejection of a workpiece are completed through the travel switches, automatic marking can be fundamentally realized, production efficiency is greatly improved and labor intensity is reduced.
Description
Technical field
The utility model belongs to the machined field, relates to the mark machine, especially a kind of feeding control circuit of metal mark machine.
Background technology
The tubular metal workpiece need be demarcated metal mark just man-hour adding.Existing mark machine does not have the workpiece automatically feeding device, can only adopt manual type carrying in place, and labour intensity is big, and workload is big, and production efficiency is low, and every operative employee can only operate two mark machines, and every operative employee's per tour can only mark more than 700.
By retrieval, there be not to find the patent publication us relevant with the utility model.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of feeding control circuit of metal mark machine is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of feeding control circuit of metal mark machine, it is characterized in that: be included in the automatic mark travel switch installed on the mark machine lift adjustment column and mark finish after the automatic ejection stroke switch of workpiece, and DC24V control power supply, the mark time relay, the mark relay, eject the electromagnetic valve coil relay, cylinder time of return relay, cylinder return solenoid valve relay, the mark time relay, the mark relay, eject the electromagnetic valve coil relay, cylinder return solenoid valve relay all is installed in parallel on the loop of 24 volts of dc sources, mark time relay series connection mark travel switch, the ejection stroke switch of mark relay serial cylinders, eject the normally closed switch of electromagnetic valve coil relay series connection ejection stroke switch and cylinder return solenoid valve relay, cylinder time of return relay connects the intermediate node of ejection stroke switch and cylinder return solenoid valve relay, the contact switch of cylinder return solenoid valve relay serial cylinders time of return relay.
Advantage of the present utility model and beneficial effect are:
1, this control circuit can make work of mark machine and workpiece release all finish by travel switch, therefore can realize the mark work of automation substantially, has greatly improved production efficiency, has reduced labour intensity.
2, this control circuit overall structure is simple, and design science is reasonable, and perfection has solved the problem that existing mark machine exists, for the automation that realizes the mark machine is laid a good foundation.
Description of drawings
Fig. 1 is a control circuit schematic diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of feeding control circuit of metal mark machine, be included in the automatic mark travel switch T1 that installs on the mark machine lift adjustment column and mark finish after the automatic ejection stroke switch of workpiece T2, and DC24V control power supply, the mark time relay sj, mark relay J 1, eject electromagnetic valve coil relay J 2, cylinder time of return relay SJ2, cylinder return solenoid valve relay J 3, the mark time relay sj, mark relay J 1, eject electromagnetic valve coil relay J 2, cylinder return solenoid valve relay J 3 all is installed in parallel on the loop of 24 volts of dc sources, mark time relay sj series connection mark travel switch T1, the ejection stroke switch S J1 of mark relay J 1 serial cylinders, eject the normally closed switch J31 of electromagnetic valve coil relay J 2 series connection ejection stroke switch T2 and cylinder return solenoid valve relay J 3, cylinder time of return relay SJ2 connects the intermediate node of ejection stroke switch T2 and cylinder return solenoid valve relay J 3, the contact switch SJ21 of cylinder return solenoid valve relay J 3 serial cylinders time of return relays.
Circuit theory of the present utility model is:
When workpiece enters the mark position, contact mark travel switch T1, this mark travel switch conducting, positive source is through the trip switch connection time relay sj, and the time relay gets electronic work, and this time relay sj is selected the make delay disconnect type for use.Time relay sj not be off-state when electric, closed immediately after electric, disconnect through setting delay time.After time relay sj must conduct, power supply elapsed time relay SJ connected mark relay J 1 coil, and mark relay J 1 gets electronic work, realizes automatic mark function when workpiece enters the mark position.
After the workpiece mark is finished, mark machine mark syringe needle resets and contacts ejection stroke switch T2, ejection stroke switch T2 closure, power supply ejects solenoid relay valve J2 through the normally-closed contact J31 connection of cylinder return solenoid valve relay J 3, relay J 2 gets electronic work, make the three position four-way electromagnetic valve action of cylinder, cylinder rod is pushed out, and ejects the workpiece of having beaten mark.
In ejection stroke switch T2 closure, power connection cylinder time of return relay SJ2, the 5 seconds exhaust hood time of return relay SJ2 contact SJ21 closures of delaying time, connect cylinder return solenoid valve relay J 3, the cylinder top rod returns, next workpiece rolls into the mark position automatically by 20 degree angle workbench, and workpiece touches automatic mark travel switch and begins the mark action, finishes a stroke of whole mark work thus.
