Background technique
With the development of railway cause, the demand of bullet train axis is also growing day by day, and people are more and more using modeling
Property forming technology produces bullet train axis, such as Multi-wedge Cross Wedge Rolling rolling mill practice, but since bullet train axis belongs to ultra-large type
Axial workpiece, wherein large scale or hollow shaft, maximum gauge nearly φ 200mm, the nearly 2200mm of maximum length, existing
In common cross wedge rolling equipment, as double roller cross wedge rolling machine will give birth to since the size of mold will strictly be matched with the size of blank
Bullet train axis is produced, mould diameter will reach φ 3000mm or more, milling train height also nearly 10000mm, equipment big in this way and mould
Tool, necessarily invests that big, at high cost, production operation is inconvenient, and enforcement difficulty is big, and the process forming is caused never to be promoted.
The mode of roller trio skew rolling can promote blank on one side, carry out Plastic Forming to blank on one side, therefore die size can
Not limited by billet size, but the main application of roller trio skew rolling equipment at present is production steel pipe part, is carried out simple
Perforation, such as Chinese patent Authorization Notice No. CN2593920Y, authorized announcement date 2003.12.24, patent name is " three rollers
Diagonal rolling pipe mill " discloses a kind of three-roller diagonal rolling pipe mill, comprising: upper and lower rack, roll assembly, roll-adjusting gears, rotary drum tune
Whole, roll balance gear, roll transmission mechanism, three roll structures are identical, 120 ° of arranged for interval are in, it is characterized in that roll
Using collar roll, collar and its roll shaft use lesser interference fit, insert at least one between collar and roll shaft
Bao Jian is provided with one and opens oil cylinder fastly with hydraulic for power between the bearing top of each roll and hydraulic balance device.But
The method that macrotype axes series parts this for hollow train shaft used roller trio skew rolling not yet because common roller trio skew rolling without
Method processes long axis, especially multistage multi-diameter shaft.
