Description
Technical field:
The invention belongs to the die forging technical field, a kind of equipment for high efficiency drop-forging forming precision parts made of non-crystalline alloy particularly is provided.
Background technology:
The short procedure and the high efficiency of forming technology, promptly shorten the technological process of production, simplify process procedure, enhance productivity, be one of main developing direction of metal material processing technology [Xie Jianxin. the current situation of materials processing technology and prospect. the mechanical engineering journal, 2003,39 (9): 29-34].And as the precision plastic forming technology of one of advanced manufacturing technology important composition, at home and abroad obtained to develop widely and used [Li Minxian etc. Frontier of Precise Shaping Technology Development. Chinese mechanical engineering, 2000,11 (1-2): 183-186].But because polycrystalline material exists crystal grain and crystal boundary, in plastic history, show anisotropy, cause unfavorable factors such as the product surface precision is low, tool abnormality wearing and tearing.Therefore, adopt novel moulding material (as bulk amorphous alloys etc.), develop forming technology rapidly and efficiently, it is significant to promote that the precision plastic forming technology obtains more massive application at high-technology field.
Bulk amorphous alloys has excellent room temperature physics and mechanical property [Inoue A, et al.Amorphous and Nanocrystalline Materials.Tokyo:Springer, 2001].But owing to reasons such as cost height, shaping processing difficulties, bulk amorphous alloys does not obtain extensive use as yet as structural material.Bulk amorphous alloys is the newtonian viscous fluid state of strain hardening and strain-rate sensitivity exponent m=1 (even if a small amount of crystallization occurs in supercooling liquid phase region (being that glass transformation temperature and crystallization begin between the temperature), it also is far longer than the requirement of general superplastic material m 〉=0.3 at the strain hardening and strain-rate sensitivity index of crossing cool region), be desirable superplastic material [Zhang Zhi person of outstanding talent waits the superplasticforming performance of .Zr base large amorphous alloy. the China YouSe Acta Metallurgica Sinica, 2004,14 (7): 1073-1077].But and its lower processing temperature, make its selecting for use of mold materials, reduce aspects such as the thermal shock of mould and energy savings had more advantage.
Therefore, develop the technology of precision plastic forming rapidly and efficiently of block non-crystalline alloy material, help further expanding the range of application of block non-crystalline alloy material and Precision Forming Technology.
Summary of the invention:
The object of the present invention is to provide a kind of equipment for high efficiency drop-forging forming precision parts made of non-crystalline alloy; collection automatic demoulding, built-in heating, gas shield, gas force technology such as fast cold be one, be used for the bulk amorphous alloys precision parts device of die-forging forming rapidly and efficiently, can carry out precision plastic forming rapidly and efficiently to various gear classes or the axial workpiece of gabarit diameter dimension 1～100mm, gauge 0.5～50mm.
The present invention includes: combination pressure head, shaping dies, ejecting mechanism, internal heater 18.Shaping dies and internal heater are placed in the die holder 12, and die holder 12 links to each other with base 17, are maintained fixed the position in shaping and knockout course.The combination pressure head is connected with forcing press by pressing head seat 1, and ejecting mechanism places on the liftout plate 16; The combination pressure head can move up and down by relative shaping dies with ejecting mechanism.The combination pressure head is made of depression bar 2, holddown spring 3, sealing flange 4, recipient 5, protective cover 6, pressure head 7; Between combination depression bar 2 of pressure head and the sealing flange 4 and the sealing between protective cover 6 and the upper cover plate 11 adopt silicone rubber O-ring to seal.But inflated with nitrogen or argon gas form protective atmosphere; to prevent bulk amorphous alloys oxidation in heating and insulating process; and can utilize protective gas flowing in pressure head and shaping die cavity; it is cold soon to the pressure of mould and workpiece to be implemented in the back that is shaped; improve forming efficiency on the one hand; simultaneously also can reduce the time of staying of drip molding to greatest extent, thereby more effectively guarantee the physical and mechanical property of large block amorphous drip molding in the high-temperature region.The combination pressure head is partly with holddown spring 3, to guarantee that recipient 5 contacts with the tight of finishing die 9 in the forming process, prevents that the slit place of blank between the two from forming overlap.Ejecting mechanism by wheel hub mould 14, unload module 15, liftout plate 16 constitutes.Pressing head seat 1 and base 17 are installed in respectively on the central sill and workbench of forming press.Internal heater 18 is made of the heater of 4～10 200～500W, 600 ℃ of maximum heating temperatures.Shaping dies is made of 2 finishing dies 9 and 10.
The groundwork process of apparatus of the present invention is: pressing head seat 1 moves downward under the driving of forming press; holddown spring 3 pressurizeds; make the certain thrust of formation between recipient 5 and finishing die 9 and protective cover 6 and the upper cover plate 11, charge into protective gas and be heated to predetermined temperature.Pressing head seat 1 moves downward once more then, make combination in the pressure head depression bar 2 and pressure head 7 with the die cavity of blank compacting and filling finishing die 9 and 10.Be shaped after the end, disconnect heating power supply, continue to feed protective gas, realize cold soon the pressure of die cavity.After being cooled to predetermined temperature, pressing head seat 1 moves upward under the drive of forcing press, and this moment, holddown spring 3 unclamped, and then the rise of combination pressure head, and slide bar 13 moves upward simultaneously.When the bolt of slide bar end with after liftout plate 16 contacts, drive and unload module 15 and wheel hub mould 14 formation of parts is ejected die cavity.
The pressure head 7 and the wheel hub mould 14 of combination pressure head are replaceable.Part to the band centre bore then adopts belt carcass bar pressure head 7 and hollow wheel hub mould 14 as shown in drawings.To solid part forming, pressure head 7 is replaced by the concora crush head, wheel hub mould 14 is replaced by solid cylinder.
Major advantage of the present invention: adopt the automatic demoulding after automatic demoulding mechanism is realized being shaped, shortened technological process and technology off time; Adopt protective atmosphere, can prevent the oxidation on formation of parts surface; Adopt built-in heater, improved blank heating efficient; It is cold soon to adopt gas to force, and has accelerated the cooling velocity of drip molding, shortens drip molding in the time of staying of high-temperature region, shortened process, and help the good serviceability of large block amorphous goods acquisition.Its main feature is that above-mentioned several technologies are become one, and helps realizing the shaping rapidly and efficiently of bulk amorphous alloys precision component.
