Description
Technical field
The present invention relates to the roll-forming method of a kind of roll-forming method of forging, particularly big-and-middle-sized aluminum alloy solid disk forging.
Background technology
On June 13rd, 2007, disclosed Chinese invention patent specification CN1978125A disclosed a kind of roll-forming method of big-and-middle-sized solid disk forging, this method is metal bar material heating after jumping-up, die mould become solid disk, solid disk heating afterloading unit location, axially rolled one-tenth solid disk forging.This method has only solved the roll forming technical problem of big-and-middle-sized solid disk forging.When adopting the rolling big-and-middle-sized aluminum alloy solid disk forging of this method, when the epicone roller of elongator is made the rolling dish base of axial feed motion towards the dish base, if its feed speed is excessive, will cause coiling base temperature when rolling and raise, be easy to generate defectives such as overheated, burning and tissue variation; If its feed speed is too small, it is too fast that the dish base dispel the heat when rolling, cause rolling motionless, or increase rolling time and rolling number of times, reduce rolling efficiency, and can cause on the disk forge piece card and fill defectives such as discontented near the peripheral position of the ring wedge angle of outer ring surface.And when adopting the rolling disk forge piece of this method, need reach requirement through changeing the rolling shape and size of disk forge piece that just can make repeatedly more, so not only increase production cost, reduced productivity ratio, and rolling technology and the quality control increase difficulty of also can giving of repeated multiple times.
Summary of the invention
The technical problem to be solved in the present invention provides the roll-forming method that a kind of axial feed velocity that uses variation is realized big-and-middle-sized aluminum alloy solid disk forging, the variation that this method axial feed velocity when rolling is descending is also adjusted roll-force thereupon, makes the solid disk forging of roll forming possess excellent tissue and performance.
For solving the problems of the technologies described above, the roll-forming method of the big-and-middle-sized aluminum alloy solid disk forging of the present invention is realized by the following technical solutions:
Aluminium alloy bar by the specification blanking is heated to deformation temperature after jumping-up, die mould become aluminum alloy solid dish base, puts into the elongator location after more described solid disk being heated to deformation temperature;
Start elongator, handle its epicone roller and make axial feed motion with the speed of 1.9mm/s towards described solid disk direction, thus the epicone roller of described elongator and down the awl roller along described solid disk axially with rolling its card of the roll-force of 4000KN～4900KN and outside its radial level, move the axially rolled of realization dish base; Described solid disk is with the speed broadening of 9mm/s～12mm/s;
When the operation of rolling proceeds to 20s, the feed speed of adjusting described epicone roller makes its rolling solid disk of speed axial feed with 0.9mm/s, the axial rolling force that described solid disk is subjected to upper and lower awl roller at this moment is 3000KN～3500KN, described solid disk under the effect of axial rolling force with the speed broadening of 8mm/s～10mm/s;
When the operation of rolling proceeds to 40s, the feed speed of adjusting described epicone roller makes the rolling described solid disk of its speed axial feed with 0.5mm/s, at this moment, the roll-force that described solid disk is subjected to upper and lower awl roller is 2500KN～3000KN, described solid disk is with the speed broadening of 5mm/s～8mm/s, finish when the operation of rolling proceeds to 70s, heating once and rolling becomes aluminum alloy solid disk forging.
Described aluminum alloy solid disk forging rolls after quench and adds the artificial aging processing; Described quenching be described solid disk forging be heated to 460 ℃～490 ℃ the insulation 9h～12h after water-cooled; Described artificial aging be described solid disk forging be heated to 150 ℃～160 ℃ the insulation 20h～22h after air cooling.
Compared with prior art, beneficial effect of the present invention is as follows:
The present invention makes its speed broadening with 9mm/s～12mm/s with axial feed velocity axial rolling solid disk under the roll-force of 4000KN～4900KN of 1.9mm/s in the rolling 20s of beginning; In rolling 20s～40s, make its speed broadening with 8mm/s～10mm/s with axial feed velocity rolling solid disk under the axial rolling force of 3000KN～3500KN of 0.9mm/s; In rolling 40s～70s, make its speed broadening with 5mm/s～8mm/s with axial feed velocity rolling solid disk under the axial rolling force of 2500KN～3000KN of 0.5mm/s; Heating once and rolling is configured as solid disk forging.
Adopt such process route, can avoid coiling base temperature when rolling and raise, produce defectives such as overheated, burning and tissue variation; Can also avoid coiling base when rolling, dispel the heat too fast, cause rolling motionless, reduce rolling efficiency and on the disk forge piece card ring wedge angle periphery position near outer ring surface fill defectives such as discontented.And adopt this method to realize the heating once and rolling shaping, and reduced rolling time and rolling number of times, be easy to technology and quality are controlled, reduced production cost, improved productivity ratio.
