Embodiment

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below Embodiment is used to illustrate the utility model, but is not intended to limit the scope of the present invention.

A kind of as shown in Figure 1, structure of die processing unit bed emergency stop control circuit in the utility model one embodiment Schematic diagram, including relay 2, emergency stop switch 1 and controller 3, wherein, the controller 3 is built-in with simple program to realize The emergency stop of the die processing unit bed is controlled.

The emergency stop switch 1 is used for the break-make for controlling the supply line, with the hole in die processing unit bed When, it can be cut off the power in time by emergency stop switch 1, arrestment operating, reaches the protection person and the safety of equipment.Specifically , one end of the emergency stop switch 1 in the present embodiment access supply line, the other end of the emergency stop switch 1 with it is described after The control coil concatenation of electric appliance 2.

The controller 3 can connect including logic switch 33 and in parallel with the input terminal of the logic switch 33 first 31 and second receiving unit 32 of unit is received, wherein, the contact of the relay 2 is patrolled by first receiving unit 31 with described Collect switch 33 to be electrically connected, first receiving unit 31 can send the first emergency stop according to the contacts status of the relay 2 Signal is to the logic switch 33；The logic switch 33 passes through second receiving unit 32 and such as remote controler, computer Deng terminal device 4 communicate to connect, the second emergent stop signal that second receiving unit 32 can send the terminal device 4 It is forwarded to the logic switch 33；And the output terminal of the logic switch 33 and the power end of die processing unit bed are electrically connected, The logic switch 33 can control the mould according to first emergent stop signal received or second emergent stop signal The power end of tool machining tool is off.
