Development Of Mobile Rivet Device For Dedicated Repair Railwagon

Short tailed rivet and rivet pin as advanced connection mode, in the railway freight car 70t is used extensively in manufacture and maintenance. According to the "Regulations" section of the railway repair truck, the truck segment Xiuzhong does not meet the technical requirements and function failure, riveting wear damaged rivet, rivet pin to re riveting.Due to the short tail pull rivet, rivet pin put into use time is short, the use of performance is good, in the car depot repair failure, lost a lot of is not need to change, so the basic configuration for riveting tooling its car depot. But as short tail pull rivet, rivet pin in the use of railway truck and to use the gradual growth of time, under the complex running condition of vehicle rivets loose, loose thimble, crack damage or loss problems also gradually. Repair special mobile short tail pull rivet, rivet pin riveting machine has a certain practical significance.Based on railway freight vehicles dedicated short tail pull rivet, rivet pin riveting technology requirements, in reference to the existing rivets long tail effect principle of riveting machine, analyzed their advantages and disadvantages and problems exist in the use, on the basis of fully considering the short tail pull rivet, rivet pin riveting need a snap the characteristics of the separation tank, puts forward the mobile short tail rivets riveting machine design scheme, main technical parameters and technical features.Through the demonstration, comparison of riveting machine design scheme, finally identified in accordance with paragraph car depot repair the library field use, on the basis of the specific scheme of the overall design, hydraulic system design, mechanical design and electric control system design. Then using, outsourcing, and the purchase made by the components combination of complete the prototype trial-manufacture, short tail was carried out on the prototype repeatedly pull rivet and rivet pin riveting test, fixed the problem in the test, finally completely meet special truck short tail pull rivet, rivet pin riveting technology requirements, reach the development goal, to complete the development of the mobile riveting machine.
