Enter carrier bar endoporus（24）It is interior so that carrier bar endoporus（24）Axis with extruding cutting post（15）Axis overlap；Then, each is cut
Cut bulge loop（18）Carrier bar endoporus is pressed downward to successively（24）It is interior, and successively to carrier bar endoporus（24）Hole wall cut, cut
The steel cuttings of generation enters each storage bits groove（19）It is interior；Then, bulge loop is extruded（16）Press downward to carrier bar endoporus（24）It is interior and right
Carrier bar endoporus（24）Hole wall extruded；Then, in carrier bar endoporus（24）Hole wall on press-fit anti-wearing liner（30）；
The connection bearing pin extruding contracting Axle mould has for realizing connection bearing pin（25）Crowded compressional axis processing：First, round steel is chosen,
And be connected round steel with hydraulic press, then by base tube（20）It is placed in the underface of round steel；Then, in the side wrap one of round steel
Layer plastic sheeting, and drive round steel to be pressed into three extruding contracting central siphons successively downwards by hydraulic press（21）It is interior, three extruding contracting central siphons
（21）The side of round steel is extruded successively, so that round steel progress elongation, which attenuates and is used as, connects bearing pin（25）；
The roller inner holes/roller axle sleeve inner hole extruding dilatation mold is used to realize roller inner holes（27）/ roller inner hole of shaft sleeve
（29）Extruding expansion processing：First, expansion column will be extruded（22）It is connected with hydraulic press, and chooses seamless steel pipe, then by nothing
Seam steel pipe is placed in extruding expansion column（22）Underface；Then, in extruding expansion column（22）Side wrap layer of plastic film,
And by hydraulic press driving extruding expansion column（22）Press downward in the pore of seamless steel pipe, extrude expansion column（22）To seamless steel pipe
Pore hole wall extruded so that the pore of seamless steel pipe is expanded and as roller inner holes（27）/ roller axle sleeve
Endoporus（29）, while so that seamless steel pipe is used as roller（26）/ roller axle sleeve（28）.
