Detailed description of the invention
Below in conjunction with the accompanying drawings a kind of detailed description of the invention of the present utility model is explained.
As shown in Figure 1 and Figure 2, this utility model provides a kind of infrared safety guard on punch, including punch press body 1, infrared
Line emitter 2, infrared receiver 3, control chamber 4, described RF transmitter 2 is respectively mounted with described infrared receiver 3
In the both sides of described punch press body die shoe 5, described punch press body 1 is provided with drift 6, and described drift 6 is arranged over block 7,
Described punch press body 1 both sides are provided with column 8, and described column 8 is provided with travel switch 9, and the contact of described travel switch 9 is arranged on
In described block 7, described travel switch 9, described infrared receiver 3 are connected with control chamber 4 respectively, and described control chamber 4 sets
There is alarm 10.
Signal amplifier 11 that described control chamber 4 includes being sequentially connected with, sound detector 12, signal driver 13, relay
Device 14, brake 15, described signal amplifier 11 is connected with described infrared receiver 3, and described sound detector 12 is with described
Being provided with travel switch 9 between signal driver 13, described relay 14, described brake 15 are connected with display 16.
Described RF transmitter 2 and described infrared receiver 3 are in left and right, the both sides phase of described punch press body die shoe 5
Right.
Described RF transmitter 2, described infrared receiver 3 are arranged on described column 8.
Described RF transmitter 2 is connected with manipulator 17.
RF transmitter 2, the quantity of infrared receiver 3 can be one or more groups, in order to of protection punch press
Or the multiple scope of operation.The most corresponding relay 14 is also one or more.
This protector can be directly mounted on the punch press of cam, and camless punch press can use a set of drift 6 stroke to open
Closing 9, the duty adjusting travel switch 9 can ensure not protect when drift 6 is up, and drift 6 goes downwards to protection during certain position
Device just start protection, and start protection point can adjust as required.
Equipment uses the duty that automatically resets, after the controlled braking of punch press, as long as the arm of operator exits guarantor
Grille, protector can automatically reset, and makes punch press automatically recover normal operating conditions, to meet the needs of continuous duty.
Operation principle: the work of protector is that the transmitting using infrared modulated light detects head with receiving conduct, and infrared ray is sent out
Emitter 2 sends a branch of invisible infrared light belt, so with regard to shape between RF transmitter 2 and infrared receiver 3
Become effective infrared protection grid, when equipment enters guard mode, as long as the arm of operator is through protection grid, red
The echlette that outside line emitter 2 is sent is obstructed, and the duty of infrared receiver 3 changes, and protector is controlled immediately
Punch press processed is braked, and makes drift 6 stop descending.And after the arm of operator leaves protection grid, infrared receiver 3 recovers former work
Making state, protector automatically resets, and punch press will continue normal work.
The manipulator 17 of this utility model protector produces a high-frequency pulse signal, and it acts on infrared transmitting tube, warp
Pulse signal after infrared low frequency reception pipe opto-electronic conversion sends into signal amplifier 11, and the output signal of signal amplifier 11 is through letter
Becoming DC level after number cymoscope 12 detection, this level controls adjustment indicating circuit and signal driver 13 respectively, and signal drives
Dynamic device 13 drives relay 14, and the work of the contact series punch press of relay 14 and braking reach protective action.When equipment from
When there is situation in inspection or circuit, alarm 10 automatic alarm, in order to repair in time, further ensure the person peace of operator
Entirely.
Making use-case: start punch press, punch press goes downwards to that when travel switch 9 is stirred by a certain position stop 7, (travel switch 9 leaves
Road), protector, by entrance protection state, now enters between RF transmitter 2 and infrared receiver 3 if any object, punching
The braking mechanism of bed can action immediately.The distance that brake back punching head 6 glides depends on the susceptiveness of braking mechanism.Object is removed red
After between outside line emitter 2 and infrared receiver 3, drift 6 may proceed to descending.When drift 6 is close to dead point, block 7 will row
Cheng Kaiguan 9 discharges (travel switch 9 short circuit), and now protector is blocked, and does not the most play protective action.When punch press is up, block 7
Travel switch 9 is allocated to other direction (travel switch 9 is still in short-circuit condition), and protector does not the most play protective action.Regulation gear
The longitudinal length of the block 7 fixed position on drift 6 and change block 7 can change the guard plot of protector.
Above an example of the present utility model has been described in detail, but described content be only of the present utility model relatively
Good embodiment, it is impossible to be considered for limiting practical range of the present utility model.All made according to this utility model application range
Impartial change and improvement etc., within all should still belonging to patent covering scope of the present utility model.
