Riveting technology applicable to track bracket

Abstract

The invention discloses a riveting technology applicable to a track bracket. Firstly, the track bracket is fixed to a riveting machine; then a rivet is heated and is subjected to plastic deformation; the rivet is arranged at the to-be-riveted position of the track bracket, and the central axis of the rivet is maintained to be consistent with the central axis of a spindle of the riveting machine; the riveting machine starts to work and exerts external force on the rivet, to obtain a riveting joint; and finally, the formed riveting joint is laminated. According to the invention, the rivet and the track bracket are riveted into a whole by adopting the hot riveting technology, the needed force in hot riveting is smaller, therefore the residual stress at the riveting position is smaller, the deformation generated is smaller, the junction surface of the rivet and the track bracket is increased after hot riveting, thus the thrust surface is increased, the stability of a track is improved, as the hot riveting technology is adopted, the joint of the rivet and the track is smoother, and a T-shaped bolt can move more flexibly in the track.

Description

technical field [0001] The invention relates to a riveting process, in particular to a riveting process for rail supports, and belongs to the technical field of rail transportation. Background technique [0002] Riveting is an ancient connection method that has been used as early as thousands of years ago. Due to its advantages such as reliable connection and no metallurgical changes in the connection process (compared with welding), it still has an indispensable position in many industries, such as Aircraft, railway vehicles, automobiles, etc. Generally speaking, riveting is essentially the plastic deformation of the rivet under the action of the rivet head (also known as the rivet rod) to form a riveted joint, thereby achieving mechanical connection. Depending on the temperature at which the rivets undergo plastic deformation, riveting can be divided into cold riveting and hot riveting. Cold riveting operates at room temperature, and the rivet produces plastic deformatio...

Problems solved by technology

Existing rail brackets include rails, sliders and rivets. Traditional rivets are riveted on the rails through cold riveting technology. Since the rivets are riveted on the rails through cold riveting technology, during the cold riveting process, the If the rivets are riveted on the track, high pressure is required, which will easily deform the joint between the track and the rivet, and the contact surface at the joint will be uneven, and the slider will easily get stuck when sliding on the turntable, thus affecting the use of the track; , due to the deformation of the rivet during the cold riveting process, the stress is concentrated at the joint, and it is easy to break; and the contact surface between the rivet and the track is small, the connection is unstable, and it is easy to fall off, thus affecting the performance of the track
