Device for high-frequency induction cladding with assistance with ultrasonic vibration and working method for device

Abstract

The invention relates to a device for high-frequency induction cladding with assistance with ultrasonic vibration and a working method for the device and particularly aims at surface treatment and reinforcement of a workpiece. The device comprises a horizontal machine tool, a PLC, a slide carriage tank, a triangular chuck, a power supply controller, a smoke removal system, an induction power supply, an infrared thermometer, an industrial water cooling circulation system, a guide rail, a ball screw, a nozzle, an ejector pin, an induction coil, an amplitude-change pole, a bracket and an ultrasonic generator. In the process of starting the induction coil for heating, and the PLC is used for controlling a motor to enable the workpiece to rotate at a certain speed (a specific speed value is obtained according to the fluidity of a molten pool in a state with assistance of ultrasonic vibration and the diameter of the workpiece), and unevenness in thickness of upper and lower cladding layers of the workpiece caused by the fact that the molten metal flows downwards due to gravity in the cladding process can be avoided. A gas protection device needs to be started before induction heating, sothat the workpiece is in an argon environment before being heated, injection of argon is stopped after the workpiece is thoroughly cooled, and the cladding layers and cladding layer influence regionscan be well prevented from being oxidized. By adding ultrasonic assistance equipment in the high-frequency induction cladding process, the quality of a bonding layer is improved to the maximum, generation of bubbles and cracks is reduced, the residual stress is eliminated, the comprehensive properties of the cladding layers are improved, the service life of the workpiece is prolonged, the production efficiency is improved, and the cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of surface engineering, and in particular relates to a device and working method for ultrasonic vibration-assisted high-frequency induction cladding. Background technique [0002] In actual industrial production, some workpieces are in the environment of alternating load, high stress and strong corrosion. Due to long-term work in harsh working conditions, various failure forms are prone to occur on the surface of the workpiece, which will greatly shorten the actual service life of the workpiece . Since the surface of the workpiece is often in direct contact with unfavorable factors, the overall failure of the workpiece basically starts from the surface. [0003] Cladding coating technology is a common surface treatment technology for metal materials. It can greatly improve the surface properties of workpieces. It has the advantages of high production efficiency, low production cost, and large-area cladding ...
