Abstract

The invention provides an automatic controlling system and controlling method for a hi-frequency hardening production line for middle-/small-modulus gears, which comprises a PLC host, an AD and DA functional module and a touch screen. After an input terminal of the PLC host and the AD module collect and process signals from the production line, an output terminal and the DA functional module control the links in the production line, so as to achieve real-time controlling of the production line. The invention is of two modes, namely automatic and manual. The touch screen allows real-time monitoring while adjusting the process parameters easily, making statistics about output of current shift and accumulated output, recording production, and displaying alarm. The invention is of high automation, can accurately control the hardening temperature of gears, improve obviously product quality and output, also improves the work environment, lightens labor intensity of workers, reduces production cost, and is especially suitable for massive production.

Description

(1) Technical field [0001] The invention relates to an automatic control system and a control method for a high-frequency quenching production line of medium and small modulus gears, and belongs to the technical field of gear high-frequency quenching processing. (2) Background technology [0002] Gear induction hardening in my country has a glorious history as a heat treatment process for hard tooth surfaces. A large number of machine tool gears, automobile and tractor gears, mining machine gears and general reducer gears all use induction hardening, corresponding high-frequency power supplies and various hardening machine tools. It is also relatively supporting. In the late 1990s, a solid-state high-frequency induction heating power supply was developed and can realize the numerical control of the quenching machine tool. At present, several domestic high-frequency equipment companies have supplied induction hardening machine tools with their leading product solid high-frequency ...
