Development Of The Riveting Device For L-Shaped Brake Beam Wear Sleeve On Wagons

Special-purpose machine for the vehicle manufacturing is the important tool of transportation insurance. It can be to improve quality and efficiency,reduce the workers' labor intensity,cut the cost or enhance security safeguard and so on. With the large-scale application of L-shaped brake beam on wagons, according to repairing technology and technical requirements of brake beam, all of the brake beam-axle testing must be carried out wet magnetic powder examination in brake beam repairing, so brake beam wear sleeve must be breaken down in the testing process ,when testing has been completed, brake beam wear sleeve will be assembled. In addition, brake beam wear sleeve will be replaced if it is to exceed wear limit.The rivet for L-shaped brake beam wear sleeve on wagons is the aluminum rivet, The majority rivets of wagons is low carbon steel rivets, these devices can not be used to L-shaped brake beam wear sleeve. Some operators adopt a sledgehammer smashing blow methods when the rivet is riveted, in this way, it can hardly be guaranteed riveting quality, and labor intensity is greater. For the above reasons, it is necessary to development of the riveting device for L-shaped brake beam wear sleeve on wagons, the riveting device is important to safe production and improve production efficiency and quality of maintenance.In this paper, According to L-shaped brake beam wear sleeve repair technology, it is put forward of rivet device design, the main technical parameters and technical features, through the demonstration of rivet design, a project according to practical requirements is ascertained, and the overall design of the program, hydraulic system design, mechanical structure design and electrical control system are designed.The rivet device main technical characteristics of the process operating are completely satisfied in the technical requirements, low labor intensity operations, a good performance, the operating environment have been greatly improved. The rivet device has been tested in Zhengzhou north rolling stock Depot, riveting over 8,000 sets of wear sleeve, the total yield was more than 99%, and operating times shorten greatly and efficiency increased more than three times, labor intensity reduced, it is very popular to operators.
