Full-automatic induction quenching machine tool for conical face of front machine cylinder of molding machine and circuit protecting method

Abstract

The invention provides a full-automatic induction quenching machine tool for the conical face of a front machine cylinder of a molding machine. The machine tool comprises an automatic feeding and conveying roller way, an industrial robot, an automatic induction quenching chamber, a loading platform, an IGBT transistor power source and a quenching liquid circular cooling system. The automatic induction quenching chamber is formed by combining a molding machine front machine cylinder loading lathe bed, an automatic lifting induction heating, spraying and quenching device, a quenching transformer, and an inductor installed on a transition bar of the quenching transformer. The lathe bed is formed by a molding machine front machine cylinder loading platform and a rotating tool clamp. The automatic lifting induction heating, spraying and quenching device is formed by a quenching transformer, a compensation capacitor, a power switching device, an accessory circuit and a water and electricityintegration quick-changing induction device. The inductor and the water and electricity integration quick-changing induction device are arranged in the conical face of the front machine cylinder of the molding machine in a suspending manner to carry out rotary induction heating or liquid spraying quenching on the conical face of the front machine cylinder of the molding machine, the industrial automatic robot takes the front machine cylinder from a pre-locating part and places the front machine cylinder to a rotary drive part, and the front machine cylinder of the molding machine is taken fromthe rotary drive part, and transferred and placed on the automatic feeding and conveying roller way.

Problems solved by technology

[0002] Most of the induction hardening equipment in the prior art adopts static induction heating and quenching technology, while dynamic continuous induction heating and quenching equipment is used. For example, the authorized announcement number is CN208234951U, and the application number is: 2018207241905. Utility model name: continuous induction hardening and tempering equipment for shaft parts. The equipment is only suitable for single-track conveying of cylindrical bearing parts, biaxial rubbing and straight-line conveying of the workpiece, so that the workpiece is subjected to induction heating and quenching during the rotating and straight-line conveying process. This single-rail conveying technology leads to low production efficiency and high degree of automation of the equipment It is not high, and the application field is limited. It is not suitable for the induction heating and quenching process of the cone surface of the front barrel of the plastic machine. There has been no good solution to this defect.
