Problems solved by technology
Welding methods such as flash welding, gas pressure welding, and thermite welding are common ways to connect ultra-long fixed-length rails into seamless track lines in stages. Due to different degrees of performance differences, problems such as inclusions, segregation and metallurgical defects caused by the welding process itself cannot be completely solved. The quality of welded joints cannot be completely satisfactory and can effectively meet the needs of the development and application of a new generation of high-strength and high-toughness rails. And the above welding methods all have different degrees of environmental pollution problems

The invention discloses a middleware rotating steel rail friction welding device. The middleware rotating steel rail friction welding device comprises a support, a clamping assembly, two clamping assemblies, a first driving piece and a second driving piece. The clamping assemblies are connected with the support and can rotate around a first axis relative to the support, each clamping assembly comprises a chuck, the chucks are suitable for clamping the middleware, the first axis is perpendicular to the plane where the chucks are located, and the two clamping assemblies are both connected to the support and can move in the extending direction of the first axis relative to the support. The two clamping assemblies are located on the two sides of the clamping assembly in the extending direction of the first axis correspondingly, the first driving piece can drive the two clamping assemblies to move in the extending direction of the first axis and in the direction close to each other, and the second driving piece can drive the clamping assembly to rotate. According to the middleware rotating steel rail friction welding device, friction welding of the steel rail can be achieved, environmental pollution can be reduced, and the welding efficiency and the joint quality are improved.
Description
technical field [0001] The invention relates to the field of welding technology, in particular to a friction welding device for a rotating rail of an intermediate piece. Background technique [0002] With the rapid growth of passenger and freight volumes in my country's railway transportation, the railway transportation system continues to move towards high-speed and heavy-duty directions. Steel rails and their welded joints and seamless track lines are an important basis for the smooth and reliable operation of railway transportation systems. Welding methods such as flash welding, gas pressure welding, and thermite welding are common ways to connect ultra-long fixed-length rails into seamless track lines in stages. Due to different degrees of performance differences, and the problems such as inclusions, segregation and metallurgical defects caused by the welding process itself cannot be completely solved, the quality of welded joints cannot be completely satisfactory and c...
