Liangshi Intelligent (stock code: 837430), as a leading domestic manufacturer of surface treatment shot blasting and coating equipment systems, has recently provided a set of equipment for strengthening the surface shot blasting of train forging tongue for a certain company.
Equipment for Shot Peening Strengthening the Surface of Train Forging Hook Tongue
Practice has shown that with the increase of train speed, total weight, and truck crane coupling speed, the longitudinal force acting on the coupler increases, thus placing higher requirements on the strength of the coupler. Preventing the occurrence of freight train separation accidents is an important issue that must be addressed while railway freight is developing towards heavy and high-speed transportation. Coupler fatigue fracture is one of the main reasons for the occurrence of freight train height accidents, which directly affects the safe and reliable operation of freight trains.
To extend the service life of the coupler, Shanghai Liangshi conducted shot peening strengthening treatment on the tensile stress concentration area of the inner arc surface of the coupler, which can effectively improve the surface tensile stress to residual compressive stress. Shanghai Liangshi Precision Control Shot Peening Machine is used for surface shot peening strengthening treatment of train forged hook tongues. After shot peening strengthening, the service life of forged hook tongues is longer than that of cast hook tongues, bringing huge economic benefits to users.
