Resistance welding machine for continuous welding seam heat treatment

Abstract

The invention belongs to the field of welding, and particularly relates to a resistance welding machine for continuous welding seam heat treatment. The resistance welding machine comprises a base, a mounting bracket, a preheating mechanism, a heat treatment mechanism, a heat preservation mechanism, fixing mechanisms and a spacing adjusting mechanism; a welding plate is arranged on the upper surface of the base; the fixing mechanisms are arranged on the upper surfaces of the left and right ends of the welding plate; the upper ends of the fixing mechanisms are fixedly connected with two ends ofthe lower surface of the mounting bracket through first hydraulic rods; the lower surface of the middle part of the mounting bracket is fixedly connected with a welding block through a second hydraulic rod; a welding head is fixedly connected with the lower surface of the middle part of the welding block; the upper end of the preheating mechanism is fixedly connected with the lower surface of theright end of the welding block; and the preheating mechanism comprises a connecting column, a mounting seat, a laser lamp, a conductive block, a sliding metal block and a fixing frame. The resistancewelding machine is mainly used for solving the problems that in the prior art, a steel structure is damaged due to too large temperature difference when steel is welded, and the temperature of a welding area is high during welding, so that parts are damaged easily and welding heat is wasted.

Description

technical field [0001] The invention belongs to the field of welding, in particular to a continuous welding seam heat treatment resistance welding machine. Background technique [0002] With the rapid development of my country's automobile, bridge, construction, home appliance and other industries that have a large demand for steel, steel companies have higher and higher requirements for the output and quality of high-standard and cost-effective steel. At present, most domestic iron and steel enterprises are gradually moving towards product transformation and equipment upgrading, and with the development of science and technology, the demand for steel styles is also increasing. As we all know, welding occupies most of the processing procedures in the production process of steel, and The weld seam treatment of steel is one of the welding methods. The existing steel weld seam usually only uses the welding head to weld the gap that needs to be processed. However, due to the ver...
