Abstract
The utility model relates to a welding tool for a copper tip of a oxygen lance and a short section of a steel tube, comprising a frame, a work piece clamping assembly, two induction heating coils, a welding gun holder, and two non-contact temperature sensors, wherein the two induction heating coils are configured in parallel and suspended; the welding gun holder is located between the two induction heating coils; a welding gun is provided on the welding gun holder; and the two non-contact temperature sensors are configured in the positions corresponding to the induction heating coils. By using two induction heating coils to quickly heat the copper tip and the short section of the steel tube, the welding tool provided by the utility model enables two work pieces to reach different optimum preheating temperatures within a short period for further welding process. With the welding tool provided by the utility model, the operator can accurately control the preheating temperatures of the cooper tip and the short sections of the internal and external steel tubes according to the process requirements, and the welding tool can realize quick heating, reduce oxide layers and increase the weld strength, so as to improve the production efficiency while ensuring the welding quality of the oxygen lance tip.
Description
Technical field
The utility model relates to a kind of welding tooling, specifically pipe pipe nipple or outer tube pipe nipple welding tooling in steel making oxygen lance copper termination and the steel.
Background technology
The copper termination of steel making oxygen gun sprayer and steel inner and outer pipe pipe nipple adopt argon arc welding to be welded as a whole.For reducing welding stress and the width that strengthens weld bond alloying component transition region; To guarantee welding quality; The method that adopts at present is with copper termination after the machined and steel tube pipe nipple, in electric furnace, is preheating to about 600 ℃, from electric furnace, takes out then; Be installed to special-purpose argon arc welding and meet sb. at the airport and go up welding, welding finishes and promptly accomplishes the manufacturing of product through cooling.The following drawback that this processing method exists: the one, warm is heating in electric furnace, insulation, the time needs one hour approximately, because of heat time heating time long, the oxidation bed thickness of workpiece outer surface generation, the weld seam slag inclusion is serious, influences the weld seam mechanical performance; The 2nd, copper termination and steel inner and outer pipes pipe nipple are in the hot installation down of high temperature, and the workman is not easy to operate, has the danger of being scalded; The 3rd, differ greatly because copper material and steel fusing point differ about 400 ℃, the coefficient of heat conduction, and identical preheat temperature makes workpiece welding back be prone to generation cold shut defective.
The utility model content
The utility model is used to overcome the defective of prior art and a kind of oxygen rifle copper termination and steel tube pipe nipple welding tooling of enhancing productivity with welding quality is provided
The said problem of the utility model is solved by following technical scheme:
A kind of oxygen rifle copper termination and steel tube pipe nipple welding tooling; Its special feature is that it comprises frame, workpiece mounting board assembly, two load coils, gun rack and two non-contact temperature sensors, wherein; Two load coils suspend setting side by side in midair; Gun rack is between two load coils, and gun rack is provided with welding gun, and the position of said two non-contact temperature sensors is corresponding load coil respectively.
Above-mentioned oxygen rifle copper termination and steel tube pipe nipple welding tooling, said mounting board assembly toply is made up of power chuck and rotation, and said power chuck, rotation is top and two load coil conllinear are provided with.
Above-mentioned oxygen rifle copper termination and steel tube pipe nipple welding tooling, said gun rack frame relatively moves forward and backward.
The problem that the utility model is to existing oxygen rifle copper termination and steel tube pipe nipple welding method weld strength is low, welding quality is difficult for assurance is improved; Designed a kind of special tooling that adopts Frequency Induction Heating and weld; This frock is carried out Fast Heating through two load coils to pipe nipple inside and outside copper termination and the steel tube; Make two workpiece reach different optimum Preheating Temperature at short notice respectively, and then carry out the argon arc welding.Adopt the utility model to carry out accuracy controlling by technological requirement to the preheat temperature of copper termination, steel inner and outer pipes pipe nipple, Fast Heating reduces oxide layer, improves weld strength, when having guaranteed oxygen rifle head welding quality, has improved production efficiency.
