Specific embodiment
The present invention will be further described in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, the high-speed rail hole-bored axle from end to end of the invention to be shaped has the feature that multi-diameter shaft 00 and is located at ladder
Inner hole 01 in axis, initial rolled piece are circular bar.
As shown in Fig. 2 to Fig. 6, a kind of forming device for high-speed rail hole-bored axle from end to end, including
Material-pulling device 1, perforating roller 2, plug 3 and three-roll cross rolling mill, three-roll cross rolling mill are equipped with oblique milling roller 4, and material-pulling device is used for
Rolled piece 21 is pushed, material-pulling device includes pusher cylinder 11 and the clamping jaw 12 for clamping rolled piece, and clamping jaw is fixed on pusher cylinder
On piston rod, the piston rod of pusher cylinder pushes to rolled piece in perforating roller.Material-pulling device further includes guide rail 13, and guide rail, which is located at, to be worn
The front of hole roller, guide rail guarantee that rolled piece can be accurately sent into perforating roller.For blocking the perpendicular of rolled piece there are two being set on guide rail
To baffle 14, the spacing of vertical baffle and the diameter of rolled piece are equal, guarantee that rolled piece does not occur during pushing to perforating roller
Offset guarantees the precision of perforation.Perforating roller and oblique milling roller are sequentially arranged along the push direction of rolled piece, and the number of perforating roller is 3,
Three perforating roller rotating Vortexes, three perforating rollers are axially mutually 120 ° of arrangements two-by-two, and what three perforating rollers guaranteed rolled piece bites essence
Degree, while the stability of perforation procedure is higher.Plug is located on the push direction of rolled piece, and plug is set close to one end of material-pulling device
There is perforating head 31, plug is coaxially arranged with rolled piece, guarantees the precision of perforation.
It further include drawing to expect device 5, drawing material device includes drawing material cylinder 51, drawing material arm 52, close switch 53 and chuck 54, institute
It states to draw and expects that arm is arranged on the piston rod for drawing feed liquid compression bar, be located at and draw on material arm close to one end of chuck, chuck packet close to switch
Outer ring chuck 541, inner ring chuck 542 and the roller 543 being located between inner ring chuck and outer ring chuck, outer ring chuck is included to be fixed on
Draw on material arm, inner ring chuck is equipped with several telescopic rods 6 for clamping rolled piece, inner ring chuck, and each telescopic rod is along inner ring chuck
It is circumferentially sequentially distributed, when close to switch triggering, rolled piece is blocked in telescopic rod stretching, guarantees the rolling quality of rolled piece.Rolled piece axially moves
It is dynamic when entering oblique milling roller, close to switch triggering, draws material cylinder and chucking work, inner ring chuck clamp rolled piece, and with rolled piece side
Side axial movement is rotated, roll forming is carried out to rolled piece by three-roll cross rolling mill.
When the present invention is implemented, whole process can be divided into perforation according to forming process and connect section, pierced billet stage and rolling rank
Section.Rolled piece is pushed into perforating roller under the action of material-pulling device first, is bitten drive rotation and be inwardly sent into gradually by perforating roller, this
When material-pulling device and perforating roller to bring rolled piece axial velocity identical, initially enter perforation stage, core when until encountering perforating head
Stick initially enters in rolled piece；After perforation proceeds through a period of time, the front end of rolled piece touches oblique milling roller, and blank is simultaneously at this time
It is not detached from perforating roller, still some is processed in perforation, is perforation and rolling while the pierced billet stage carried out at this time.Into
In this stage, rolled piece triggering is close to switch, and inner ring chuck firmly grasps rolled piece at this time, and clamping jaw unclamps rolled piece, and rolled piece is detached from material-pulling device
By drawing material device traction, rolled piece is moved axially in rotation, and the movement speed of chuck and the axis movement speed of rolled piece are equal, interior
The revolving speed of the revolving speed and rolled piece that enclose chuck is equal；Continue pierced billet and formally enters rolling until the tail portion of blank is detached from perforating roller
Stage completely disengages tube rolling oblique milling roller to rolled piece, and rolling terminates, rolled piece and plug is subsequent to be separated by winding arbor extraction press.
The beneficial effects of the present invention are: rolled piece perforated roller and perforating head carry out perforation processing, plug is direct after perforation
It stays in rolled piece, then and rolled piece carries out roll forming through three-roll cross rolling mill together, disposably processes high-speed rail hole-bored axle from end to end, work
Skill process shortens, and production efficiency is substantially improved；Perforating head perforates to rolled piece, and plug directly stays in one in rolled piece after perforation
It rises and is rolled, plug is good with rolled piece conjugation, and rolling quality is stablized；When oblique milling roller rolling rolling stock, change of the rolled piece in addition to itself
Shape can also move axially under the drive of oblique milling roller, solve the problems, such as that rolling mold width is influenced by length of rolled piece, mold ruler
It is very little substantially to reduce, it is easy to implement.
