Embodiment 1

[0059] When the high-frequency welding machine 4 is working, the shape of the outer burr in the welding zone 2 is collected;

[0060] Comparing and analyzing the width and height of the received outer burr shape with the preset outer burr shape width and height respectively, and generating a first error value according to the comparative analysis results of the outer burr shape;

[0061] A corresponding adjustment amount of the high-frequency welder 4 is generated according to the first error value, and the working power of the high-frequency welder 4 is correspondingly adjusted according to the adjustment amount.

Embodiment 2

[0063] When the high-frequency welding machine 4 is working, collect the spark state in the welding zone 2;

[0064] comparing and analyzing the color and brightness in the received spark state with the color and brightness in the preset spark state, and generating a second error value according to the spark state comparative analysis results;

[0065] An adjustment amount corresponding to the high frequency welder 4 is generated according to the second error value, and the working power of the high frequency welder 4 is correspondingly adjusted according to the adjustment amount.

Embodiment 3

[0067] When the high-frequency welding machine 4 is working, the spark state and the shape of the outer burr in the welding zone 2 are collected;

[0068] Compare and analyze the color and brightness of the received spark state with the color and brightness of the preset spark state, and at the same time, compare the width and height of the received outer burr shape with the width and height of the preset outer burr shape Perform comparative analysis, generate corresponding first error value and second error value according to the comparative analysis results in the shape of the external burr and the spark state, and neutralize the generation of the first error value and the second error value in the high-frequency welding The corresponding adjustment amount of the welding machine 4, and the working power of the high-frequency welding machine 4 is correspondingly adjusted according to the adjustment amount.

Abstract

The invention provides an intelligent control system and method for high-frequency welding. The system comprises a machine vision system used for collecting welding parameters in a welding area when a high-frequency welding machine works and an analyzing system used for performing contrastive analysis on the received welding parameters and preset welding parameters one by one, generating adjustment amount corresponding to the high-frequency welding machine according to contrastive analysis results and correspondingly adjusting the working power of the high-frequency welding machine according to the adjustment amount. According to the intelligent control system and method for high-frequency welding, contrastive analysis is performed on the welding parameters and the preset welding parameters one by one, an error value of each welding parameter and the corresponding preset welding parameter is calculated, the corresponding power adjustment amount of the high-frequency welding machine is generated by synthesizing all the welding parameter error values, the closed-loop control system is formed, and the purpose of intelligently adjusting the power of the high-frequency welding machine is achieved; the adjusting time of the high-frequency welding machine is greatly shortened, and the working efficiency of the high-frequency welding machine is improved; meanwhile, the intelligent degree of the high-frequency welding machine is improved, and the working intensity of operating personnel is greatly lowered.

Description

technical field [0001] The invention relates to the technical field of high-frequency welded pipe equipment, in particular to an intelligent control system and method for high-frequency welding based on high-frequency welded pipes. Background technique [0002] The high-frequency welded pipe unit uses steel coils as raw materials. Through a series of longitudinal deformation processes, the strip steel is deformed into open round pipes. After being welded by a high-frequency welding device, welded pipes are produced. High-frequency welded pipe has the advantages of low production cost, high roundness of steel pipe, high conveying efficiency, easy maintenance of one-sided weld, and low residual stress. And it is widely used in the fields of building structure, pipeline transportation, etc. Among them, the products produced include structural pipes, oil casing pipes, line pipes, etc. [0003] However, the existing high-frequency welding intelligent control system has the probl...
