Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage:
the applicant discover through long-term practice, and existing pneumatic press is after the both hands button is connected, and master cylinder is down action immediately just; After the time timing of setting finishes; Master cylinder just up resets automatically, and master cylinder also can not be controlled and stops or up resetting even both hands are thrown off button at once in down process of action; So, the operating personnel that action is fast causes weighing wounded the accident generation because of early hand being put in easily.The utility model has carried out optimizing improvement to the circuit control section of original pneumatic press; Lower end part at the cylinder actuating length has increased the limit induction protection switch; The master cylinder that has kept original pneumatic press must be pinned the control that just can down move by the both hands button, has realized pneumatic press simultaneously after the both hands button is connected, in master cylinder action process down; After any one hand of operating personnel is thrown off button; Master cylinder can be controlled immediately and stop down to move and up reset automatically, and therefore in the process of whole master cylinder action, operating personnel's both hands must be pushed down button from start to finish; Guarantee to arrive the limit induction position of the switch of lower end part at master cylinder; After making the limit induction switch motion, just can unclamp both hands and make pneumatic press entering timing accomplish whole die-cut process, the accident that also can not be weighed wounded after fast operating personnel puts in hand of having guaranteed thus to move takes place; Management has played impetus to safety and production, makes operating personnel's personal safety also obtain effective guarantee.
Description of drawings
are done further detailed explanation below in conjunction with accompanying drawing and concrete embodiment to the utility model.
Fig. 1 is the structural representation according to the control system of the flexible electric circuit board pneumatic press of the utility model;
Fig. 2 is the sketch map according to the main control loop of the control system of the flexible electric circuit board pneumatic press of the utility model;
wherein: 1, master cylinder; 2, control gas circuit; 3, button; 4, frame; S3, limit induction switch; FU, short-circuit protector; S1, first hand switch; S2, second hand switch; C1, the time relay; C2, first auxiliary reclay; C3, second auxiliary reclay; C4, master cylinder control relay.
The specific embodiment
are as illustrated in fig. 1 and 2, and the critical piece of flexible electric circuit board pneumatic press comprises frame 4, master cylinder 1 and control system.The utility model relates generally to the improvement to the control system of flexible electric circuit board pneumatic press, particularly to the improvement of control circuit.Control system in the face of the flexible electric circuit board pneumatic press carries out detailed explanation down.
In
present embodiment, the control system of flexible electric circuit board pneumatic press comprises control circuit (comprising main control loop) and the control gas circuit 2 that is used to control master cylinder 1 action.Be provided with short-circuit protector FU, the first manual switch S 1 and the second manual switch S 2 of serial connection mutually in the main control loop, in main control loop, also be provided with time relay C1, the first auxiliary reclay C2, the second auxiliary reclay C3 and master cylinder control relay C4.The first manual switch S 1 and the second manual switch S 2 are controlled switching through two buttons 3 respectively.Lower end part at master cylinder 1 actuating length is provided with limit induction switch S 3.Behind the coils from parallel connection of coils of the coil of the coil of the coil of time relay C1, the first auxiliary reclay C2, the second auxiliary reclay C3 and master cylinder control relay C4; Serial connection is gone in the main control loop; The normally closed interlock of said time relay C1 is serially connected between the coil of the second manual switch S 2 and the first auxiliary reclay C2; One group of normally open contact of the first auxiliary reclay C2 is serially connected between the coil of the second manual switch S 2 and master cylinder control relay C4; Another group normally open contact of the first auxiliary reclay C2 and the normally open contact serial connection of the second auxiliary reclay C3; And parallelly connected with the first manual switch S 1 and the second manual switch S 2, said limit induction switch S 3 inserts in the wire loop of the second auxiliary reclay C3, and it is closed when master cylinder 1 arrives its position.
The control principle of the control system of present embodiment is following:
After
pneumatic press starts; After the operating personnel presses two buttons; The first manual switch S 1 and second manual switch S 2 closures; Time relay C1 gets the electrician and does, and time relay C1 normally-closed contact remains closed and makes the first auxiliary reclay C2 get electrician's work, and first auxiliary reclay C2 work makes two groups of normally opened contacts of the first auxiliary reclay C2 closed; The first auxiliary reclay C2 normally opened contact closure works on power master cylinder control relay C4, makes master cylinder 1 begin action downwards thus.In the stroke before master cylinder 1 does not arrive limit induction switch S 3; If unclamp any one corresponding button 3 of S1 or S2; Master cylinder 1 will upwards reset because of master cylinder control relay C4 dead electricity stops action immediately, and only in master cylinder 1 action arrival downwards limit induction switch S 3, the second auxiliary reclay C3 gets the electrician and does; Make the C3 normally opened contact closed; Form the loop with the closed contact of the first auxiliary reclay C2 simultaneously, and then make first switch S 1 and second switch S2 accomplish control, this moment, operating personnel's both hands can be totally released two buttons 3.Master cylinder 1 is accomplished die-cut process automatically in the predefined reference time delay of time relay C1.Time relay C1 timing finishes the back homing action; Time relay C1 normally-closed contact breaks off the first auxiliary reclay C2 dead electricity is resetted; The first auxiliary reclay C2 resets and makes two groups of contacts of the first auxiliary reclay C2 recover often to open; The C2 contact recovers often to open master cylinder control relay C4 dead electricity is quit work, and makes master cylinder 1 upwards begin to move to reset mode thus.
to sum up; The utility model is in master cylinder action process down, and after any one hand of operating personnel was thrown off button, master cylinder can be controlled immediately and stop down to move and up reset automatically; Therefore in the process of whole master cylinder action; Operating personnel's both hands must be pushed down button from start to finish, guarantee to arrive at master cylinder the limit induction position of the switch of lower end part, make the limit induction switch motion after; Just can unclamp both hands makes pneumatic press entering timing accomplish whole die-cut process; The accident that also can not be weighed wounded after fast operating personnel puts in hand of having guaranteed thus to move takes place, and management has played impetus to safety and production, makes operating personnel's personal safety also obtain effective guarantee.
the utility model can thoroughly solve operating personnel's in the operation process potential safety hazard; And do not influence all functions of existing equipment; Having overcome for a long time the pneumatic press middle action can't stop and having a technical problem that production accident occurs; Under equal operating position and do not increase under the situation of energy consumption; Make equipment reach the operational effect of lasting highly effective and safe fully, and, also reduced the generation of defective products to a great extent because of having realized the middle function that stops to reset.
are above has done detailed description to the utility model, but the utility model is not limited to the above embodiments.All equivalences of doing according to the spirit of the utility model change or modify, and all should be encompassed in the protection domain of the utility model
