1. , for a gap self-checking device for drawbead mould, it comprises bedplate, convex mould base, punch insert, die plate insert and for driving the servomotor of adjusting screw(rod), it is characterized in that:

  • described punch insert is fixedly installed on described convex mould base;

    Described bedplate is provided with accommodation cavity, the inside of described accommodation cavity is provided with the first guide rail, second guide rail and adjusting screw(rod), described first guide rail and the second guide rail are fixedly installed on the two bottom sides within described accommodation cavity respectively symmetrically, the two ends of described adjusting screw(rod) are separately fixed on two sidewalls of described bedplate by fixture, described first guide rail is provided with one first slide block, described second guide rail is provided with one second slide block, described first slide block and the second slide block are set on the contrary threaded portion of the hand of spiral that is positioned at described adjusting screw(rod) both sides respectively,Described die plate insert is fixed on described first slide block and the second slide block;

    WithDescribed first slide block is provided with the first displacement transducer, described second slide block is provided with second displacement sensor, described first displacement transducer is connected computer with described second displacement sensor by A/D conversion equipment, and the output of described computer connects the input of described servomotor;

    Described first displacement transducer and described second displacement sensor measure the real-time moving interval S along described adjusting screw(rod) between described first slide block and described second slide block respectively in real time, described computer installation has memory cell and judging unit, described judging unit is provided with displacement threshold value D, described memory cell can store the real-time moving interval S that described first displacement transducer and described second displacement sensor are uploaded, real-time moving interval S and displacement threshold value D compares by described judging unit, and the action of described servomotor is controlled according to comparative result, and then the spacing controlled between described first slide block and described second slide block.
