In hydraulic press safety control circuit; usually safety relay can be adopted to control the safe components and parts such as safe scram button, safety door switch; because counting of safety relay is different with function; in the safety control circuit of a hydraulic press, need multiple safety relay use together; circuit more complicated; wiring is loaded down with trivial details; each other can not communication; the security system of the rigid line connected mode of use safety relay or relay unit is difficult to realize complicated security control, is also difficult to adapt to demand that is newly-increased or that change.Therefore just must develop a kind of optional, multiple functional, easy-to-connect and automatic cyclic control circuit that can programme arbitrarily of counting, through retrieval, not find the same or analogous control circuit with the utility model.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of optional, multiple functional, easy-to-connect and automatic cyclic control circuit that can programme arbitrarily of counting.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of hydraulic press automatic cyclic control circuit based on G9SP safety governor, its innovative point is: comprise G9SP safety governor, electromagnet YV1, YV2, rotary switch SA, inductive switch SQ1, SQ2 and shearing button SB4 and stopping crawl backhaul button SB1, after the normally open contact 2-14 of rotary switch SA connects with the auxiliary normally open contact 14-5 of G9SP safety governor, carry out in parallel with the auxiliary normally open contact 2-5 of G9SP safety governor with the normally open contact 2-5 shearing button, then connect with the auxiliary normally closed interlock 5-11 of G9SP safety governor, and then to connect with G9SP safety governor and form loop,
The normally open contact 1-10 of rotary switch SA and the normally open contact 10-13 of inductive switch SQ2 carry out connecting and carry out being composed in series loop with G9SP safety governor again;
The normally open contact 2-6 of inductive switch SQ1 connects with the normally open contact 1-6 and normally closed interlock 1-2 that stop crawl backhaul button SB1 with after the auxiliary normally open contact 2-6 parallel connection of G9SP safety governor, and then connect with the auxiliary normally closed interlock 6-12 of G9SP safety governor, finally carry out being composed in series loop with G9SP safety governor again, the normally closed interlock of rotary switch SA is connected in the loop of G9SP safety governor;
Main contact 1-8 and the electromagnet YV2 of G9SP safety governor form loop;
Main contact 1-7 and the electromagnet YV1 of G9SP safety governor form loop;
Above-mentioned all loops are all connected in parallel in composition control circuit in circuit.
The utility model has the advantage of: 1.G9SP safety governor is not only counted optional, multiple functional, easy-to-connect, and can programme arbitrarily, achieves the communication between other components and parts easily.
The Programmable Logic Controller of 2.G9SP safety governor brings the free degree and flexibility to safe design, can adapt to complicated security control, reduces design and the man-hour needed for debugging.
3.G9SP configurator has the guide function simplifying System's composition and I/O setting, and does not connect the analog functuion that main body can carry out action inspection, even if for the first people utilizing programming to carry out safe design, these functions are easily understood equally.
It is the large advantage utilizing programming to carry out safe design that the designing program of 4.G9SP safety governor can freely be carried, design data is kept in storage box, by extending transversely for design data to other G9SP, the debugging man-hour of equipment can be greatly reduced without the need to computer.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of the utility model based on the hydraulic press automatic cyclic control circuit of G9SP safety governor.
Detailed description of the invention
A kind of hydraulic press automatic cyclic control circuit based on G9SP safety governor as shown in fig. 1, comprise G9SP safety governor, electromagnet YV1, YV2, rotary switch SA, inductive switch SQ1, SQ2 and shearing button SB4 and stopping crawl backhaul button SB1, after the normally open contact 2-14 of rotary switch SA connects with the auxiliary normally open contact 14-5 of G9SP safety governor, carry out in parallel with the auxiliary normally open contact 2-5 of G9SP safety governor with the normally open contact 2-5 shearing button, then connect with the auxiliary normally closed interlock 5-11 of G9SP safety governor, and then to connect with G9SP safety governor and form loop, the normally open contact 1-10 of rotary switch SA and the normally open contact 10-13 of inductive switch SQ2 carry out connecting and carry out being composed in series loop with G9SP safety governor again, the normally open contact 2-6 of inductive switch SQ1 connects with the normally open contact 1-6 and normally closed interlock 1-2 that stop crawl backhaul button SB1 with after the auxiliary normally open contact 2-6 parallel connection of G9SP safety governor, and then connect with the auxiliary normally closed interlock 6-12 of G9SP safety governor, finally carry out being composed in series loop with G9SP safety governor again, the normally closed interlock of rotary switch SA is connected in the loop of G9SP safety governor, main contact 1-8 and the electromagnet YV2 of G9SP safety governor form loop, main contact 1-7 and the electromagnet YV1 of G9SP safety governor form loop, above-mentioned all loops are all connected in parallel in composition control circuit in circuit.
