一、前言轮胎压辊包边成型机在我国一直以触点式步进选线器作为成型动作的控制部件。步进选线器属于电磁机械结构形式,有一组动触点和一组静触点。接点的切换由电磁铁的吸动来推动一个棘轮,棘轮与动触点连成一体,棘轮带动动触点,使其与各静触点接触,完成转换实现成型的全过程。正由于这种机械结构,日长时久产生了磨损和氧化,使触点接触不良引起故障,影响生产。
First, the foreword Tire pressure roller wrapping machine in our country has been to step-by-step contact wire as a molding action control components. Stepper wire selectors belong to the form of electromagnetic mechanical structure, with a group of moving contacts and a group of static contacts. Contact switching by the electromagnet suction to promote a ratchet, ratchet and moving contact into one, the ratchet belt moving contact, make contact with the static contact, the conversion completed the whole process of forming. It is precisely because of this mechanical structure, Japan wear and oxidation for a long time to make contact with poor contact failure, affecting production.
