Steel induction heating solid phase welding method and butt welding machine tool

Abstract

The invention relates to a steel induction heating solid phase welding method and a butt welding machine tool. The butt welding machine consists of a machine body and a butt welding clamp, wherein the machine body mainly comprises a machine tool body, an electric cabinet, a welding controller, a left main guide rail, a left main slide rail, a left induction heating transformer, a tool holder, a right induction heating transformer, a right main guide rail, a right main slide rail and a hydraulic cabinet; and the hydraulic steel tube and steel rail butt welding clamp mainly comprise a left hydraulic cylinder, a left hydraulic cylinder fixing seat, a left steel rail fixing clamp, a left induction heating ring, a connecting rod of a piston rod, a right induction heating ring, a right steel rail fixing clamp, a right hydraulic cylinder fixing seat and a right hydraulic cylinder. The butt welding clamp is arranged on the end face to be welded of the steel product; and the induction heating rings are sleeved on the end face to be welded of the steel product respectively; an induction heating power supply is connected with the primary of the induction heating transformer by a cable, and the secondary of the induction heating transformer is connected with the induction heating rings respectively; and the induction heating rings can heat the end faces to be welded of two steel products to a thermoplastic state in a shot time, and the upsetting pull force is generated on the welding clamp, so that the two steel products are welded together.

Description

Technical field [0001] The invention relates to an induction heating solid phase welding method and a butt welding machine tool for steel materials. Specifically, it relates to an induction heating solid phase welding method and a butt welding machine tool for butt welding steel rails, round steel, steel pipes and the like. Butt welding of steel rails, round steel, steel pipes and other steel materials used by railway mines, industrial and civilian construction, water conservancy and electric power, and petrochemical enterprises. Background technique [0002] Welding is a basic mechanical manufacturing method. In industrial production, butt welding of rails, round steel, and steel pipes mainly uses gas pressure welding, flash welding and arc welding. [0003] Because of the high carbon content of the rails used by railway mining enterprises, fusion welding cannot be used for butt welds of rails. Therefore, gas pressure welding is generally used. The method is: two steel rails to b...

AI Technical Summary

Problems solved by technology

In order to ensure the welding quality of the steel pipe in the overhead welding position, only the foreign "automatic root welding machine" with complex structure and expensive price can be used to weld the root weld.

Using this welding method, it is necessary to purchase foreign "automatic root welding machines" with complex structures and expensive prices for root weld welding

Although the purchase of welding equipment has been increased, it only solves the technical problems caused by the single-sided welding and double-sided forming all-position welding process, but cannot minimize the welding time of steel pipes; due to the large number of welding layers, the welding time is long. , large thermal deformation, and large welding internal stress; it not only affects the safe use of the pipeline, but also increases the welding workload and labor intensity of the welding workers, affecting the pipeline installation period
