Abstract

The invention discloses a subway rotating arm joint press-fitting and flanging process and device. The subway rotating arm joint press-fitting and flanging process comprises the steps of flanging of one end of a third rotating arm joint outer sleeve, rotating arm joint press-fitting and flanging and fastening of the other end of the third rotating arm joint outer sleeve. A flanging device for one end of the third rotating arm joint outer sleeve comprises a first machine table, a flanging base, a flanging two-section mold, a flanging middle mold and a flanging press head. A rotating arm joint press-fitting device comprises a second machine table, a common base, a common two-section mold, a common middle mold, a guide barrel and a press-fitting press head. A flanging device for the other end of the third rotating arm joint outer sleeve comprises the second machine base, the common base, the common two-section mold, the common middle mold and a flanging press head. According to the subway rotating arm joint press-fitting and flanging process and device, the structure is simple, and operation is convenient; press-fitting of a first rotating arm joint outer sleeve and a second rotating arm joint outer sleeve is in place, the rebound force of rotating arm joint rubber is overcome, and meanwhile flanging outer sleeve two-end fastening is achieved; the size is precise; and the rotating arm joint rigidity performance is reliable.

Description

technical field [0001] The invention relates to the technical field of rail vehicle manufacturing, in particular to a press-fitting and flanging process and device for a pivoting arm node of a subway. Background technique [0002] The pivoting arm node refers to the elastic element installed in the pivoting arm of the bogie axle box, which is used to transmit traction force and lateral force, and realize wheel set positioning. The vulcanized body of the pivot arm node refers to the semi-finished state of the pivot arm node that has not been press-fitted and flanged after vulcanization. The vulcanized body of the pivot arm node includes jacket one 1 and jacket two 2, such as figure 1 As shown (that is, the semi-finished state before pressing and flanging). [0003] The pivoting arm node is installed on the pivoting arm, connects the bogie frame and the axle box, transmits the traction force and lateral force between the frame and the axle box, bears part of the suspension fo...
