Abstract
The utility model relates to a safety protector for die stamping equipment. A protection circuit is arranged on the die stamping equipment, mainly comprises a power, a photoelectric inductive switch which is connected with the both ends of the power in parallel, and a relay which is connected between the positive of the power and the output of the photoelectric inductive switch in parallel. The normal closed switch of the relay is inserted into the power circuit of the die stamping equipment. The photoelectric inductive switch is provided between the die stamping equipment and the operator. The device has simple structure, lower cost, smaller power consumption, predominant performance, high safety and reliability and convenient installation.
Description
Technical field
The utility model relates to a kind of pressing equipment protector.
Background technology
Pressing equipment does not mostly have any safety guard at present, all is artificial control, is easy to have an accident; Even some is equipped with safety precautions, but exist cost higher, influence production efficiency, use shortcomings such as inconvenience.
The utility model content
The pressing equipment protector that provides a kind of cost lower, safe and reliable is provided the utility model purpose.
To achieve these goals; the utility model adopts following technical scheme: pressing equipment is provided with a holding circuit; mainly comprise power supply, be attempted by both ends of power photoelectric sensor switch, be attempted by the relay between positive source and the photoelectric sensor switch output; the normally closed switch of relay seals in the power circuit of pressing equipment, and photoelectric sensor switch is arranged between pressing equipment and the operator.
Go back and be connected to the protection indicator lamp or the alarm of connecting in the described holding circuit with the relay normally open switch.
Described photoelectric sensor switch and associated components can be fixed on the pressing equipment by permanent magnet.
This apparatus structure is simple, and cost is lower, and power consumption is less, and superior performance is safe and reliable, is convenient to move, and mounting means is versatile and flexible.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a plan structure schematic diagram of the present utility model;
Fig. 3 is circuit theory diagrams of the present utility model.
The specific embodiment
Embodiment: a kind of as Figure 1-3 pressing equipment protector; this protector power supply becomes DC12V to alternating current 220V, 50Hz with transformer K; H is the power switch of alternating current; R is that fuse plays the holding circuit effect; L1 is the power supply indication, and transformation is after rectifier bridge F and filter capacitor E flow to downstream circuitry.This protector chief component has many groups photoelectric sensor switch 2 of being attempted by both ends of power, is attempted by the relay between positive source and photoelectric sensor switch 2 outputs.Many group photoelectric sensor switch 2 are installed between the mould of operator and punch press 1 relatively, form a separation net of forming by infrared ray 7 light beams in the space between operator and patrix 3, counterdie 4, be provided with three photoelectric sensor switch 2 in the present embodiment, receiving tube A, the B of photoelectric sensor switch 2, C are high level because of the irradiation that is subjected to transmitting tube A1, B1, C1 makes its output under the normal condition, so relay D is failure to actuate, its normally closed some D1 conducting seals in downlink electrical magnet valve loop, and equipment can operate as normal.Relay and other circuit block are contained in the protection box 5.Work as A; B; when any Ray Of Light of the acceptance of C is blocked; just can make its output become low level; to the coil electricity adhesive that makes relay D; D1 disconnects; cut off mould slide block down magnetic valve loop; the pressing equipment power circuit of electric appliance box 6 the insides disconnects; make slide block static immediately; owing to go back and be connected to the protection indicator lamp or the alarm of connecting in the holding circuit with the relay normally open switch; so with the D2 that opens often; the D3 closure; protection indication L2 is bright, and alarm buzzer L3 sender reminds the operator that protection is opened, when arm when promptly all light beams are not blocked in the forbidden zone system can recover normal at once.The quantity of photoelectric sensor switch 2 can suitably increase and decrease according to actual conditions, is as the criterion meeting the demands.Main box and annex can be fixed with permanent magnet, make conveniently moving, and mounting means is versatile and flexible.
Claims (3)
1, a kind of pressing equipment protector; it is characterized in that: pressing equipment is provided with a holding circuit; mainly comprise power supply, be attempted by both ends of power photoelectric sensor switch, be attempted by the relay between positive source and the photoelectric sensor switch output; the normally closed switch of relay seals in the power circuit of pressing equipment, and photoelectric sensor switch is arranged between pressing equipment and the operator.
2, protector according to claim 1 is characterized in that: go back and be connected to the protection indicator lamp or the alarm of connecting with the relay normally open switch in the described holding circuit.
3, protector according to claim 1 and 2 is characterized in that: described photoelectric sensor switch and associated components can be fixed on the pressing equipment by permanent magnet.
