Abstract
The invention discloses an automatic protection device of a punching machine, which is characterized in that both sides of the front end of a worktable (1) are provided with a luminous column (2) and a receiving column (3), wherein the luminous column is provided with a light curtain sensor; one side of a slider (4) is provided with an upper inductive sensor and a lower inductive sensor (6) and (7) through a support (5); and a circuit board (8) is arranged in the worktable. The invention solves the problem of frequent accident of the traditional punching machine, does not need to stop when clearing leftover materials and has the advantages of inductive sensor and light curtain sensor double protection, obvious safety effect, simple structure, low production cost, wide market prospect and the like, and moreover, the modification becomes convenient on the basis of the traditional punching machine.
Description
Technical field
The present invention relates to the machine security apparatus field, a kind of more precisely press bed automatic safety device that utilizes inductance type transducer and light curtain sensor double protection.
Background technology
Press bed is the requisite machinery of five metals manufacturing industry, and first " killer " of industrial accident also is that press bed causes, and the height of accident of broken fingers is startling.Though people also develop safety guard constantly, all fail thoroughly to solve hidden danger.Trace it to its cause and be: some adopts single light curtain sensor, as long as have thing or hand to enter the light curtain, machine promptly stops; therefore, operating personnel need remove the other leftover pieces of mould, when instrument one stretches into; machine stops immediately; therefore an order of classes or grades at school is shut down and is reached up to a hundred times more than, directly influences the operation progress, and the workman who pays on a piecework basis is difficult for accepting; some adopts correlation type infrared ray control technology; but do not control press bed down towards the time inertia, can not brake hard, accident still happens occasionally.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, can not shut down, have inductance type transducer and light curtain sensor double protection, the significant press bed automatic safety device of safe effect when a kind of removing rim charge is provided.
The objective of the invention is to adopt following technical measures to realize: the design main points: use up act start and stop of circuit control slide motor, two inductance type transducers are housed in this circuit, the break-make of control light curtain circuit, when the output of two inductance sensors is " 1 ", light curtain circuit is just worked, when as long as two inductance sensors wherein have one to be output as " 0 ", light curtain circuit is not worked, explain in conjunction with practical operation: when slide block is above two inductance sensors, the light curtain sensor is not worked, when slide block descends, through first sensor (on) time still do not work, but one when entering second sensor (descending), the light curtain sensor is worked immediately, as this moment hand or thing still inside, motor promptly stops, when slide block rises, when leaving second sensor (descending), the light curtain is not worked again, is convenient to operating personnel and handles leftover pieces or other affairs, has guaranteed safe reliability.
A kind of press bed automatic safety device; form by light curtain sensor, inductance type transducer, circuit board; it is characterized in that: front end both sides on workbench; the Column being luminous G1 and reception post G2 of light curtain sensor are housed; by support upper and lower two inductance type transducers are housed in slide block one side; circuit board is housed in the workbench, is equipped with on the circuit board: logic control circuit, drive circuit, relay K.
Remarkable result of the present invention: can not shut down, have inductance type transducer and light curtain sensor double protection when removing rim charge, safe effect is remarkable, simple in structure, convenient in the existing press bed transformation of the way, the increase production cost is low, and wide market prospects are arranged.

Accompanying drawing 2 is an operation principle block diagram of the present invention;
Accompanying drawing 3 is a wiring diagram of the present invention.
The present invention is further elaborated below in conjunction with accompanying drawing.
The specific embodiment
Referring to figure, front end both sides on workbench 1, the Column being luminous (G1) 2 of light curtain sensor is housed, with reception post (G2) 3, by support 5 upper and lower two inductance type transducers 6,7 are housed in slide block 4 one sides, circuit board 8 is housed in the workbench, is equipped with on the circuit board: logic control circuit, drive circuit, relay K.
Claims (2)
1. press bed automatic safety device; form by light curtain sensor, inductance type transducer, circuit board; it is characterized in that: go up the front end both sides at workbench (1); the Column being luminous (2) of light curtain sensor is housed; with reception post (3); by support (5) upper and lower two inductance type transducers (6), (7) are housed in slide block (4) one sides, circuit board (8) is housed in the workbench.
