Abstract

The utility model discloses a kind of electro plasticity hot forging device for metal bar, mainly include attemperator, pulse current bringing device, forging apparatus, the device combines electro plasticity effect technology and electromagnetic induction heating technology on the basis of conventional hot forging device, according to influence of the electro plasticity effect in intermetallic composite coating, the present apparatus can be reduced the resistance of deformation in forging process by the way that pulse current is introduced into forging;Meanwhile, electric current is passed through pulse current in high-temperature solid metal can also play a part of crystal grain thinning;According to electromagnetic inductive heating principle, the induction coil in the present apparatus can play insulation effect;The present apparatus reduce the forging force in metal bar hot forging processing and increase after single heating can process time so that production efficiency is improved, and energy loss is reduced, product quality to improving.

Description

A kind of electro plasticity hot forging device for metal bar
Technical field
The utility model, which is related to during a kind of hot forging process, to be passed through pulse current by forging and contains attemperator Electro plasticity hot forging device.
Background technology
Forging technology is that one kind applies pressure using metal forming machinery to metal stock, makes it produce plastic deformation to be had There is the processing method of certain mechanical performance, definite shape and size forging.Forging can be divided into cold by temperature of the blank in processing Forging and hot forging.Cold forging is usually carried out at room temperature, and hot forging is processed in the recrystallization temperature higher than blank metal.Compared to Cold forging, hot forging has the resistance of deformation of metal low, thick as-cast structure becomes the new organization of small grains, and as-cast structure lacks Fall into and reduced, the mechanical performance of steel is improved, the advantages of plasticity of steel is improved.But in forging large volume forging When, it is still desirable to very big forging force, the influence along with heat dissipation metal to forging process make it that the energy resource consumption of hot forging is larger, Processing efficiency is relatively low.The electro plasticity effect and electromagnetic induction heating technology of metal are incorporated into hot forging process, on the one hand, pulse Electric current can reduce forging force during hot forging, and electromagnetic induction heating can play insulation effect, effectively improve the hot-working time, So that production efficiency is improved, energy loss is reduced.On the other hand, pulse current can also play refinement high-temperature metal The crystal grain of solid, improves product quality.
The content of the invention
For background above technology, the utility model, which is provided a kind of hot forging process suitable for metal bar, is related to electric modeling The hot forging device of property effect and electromagnetic induction heating technology.
The utility model is realized by following technical solution:The present apparatus mainly includes attemperator, pulse current and applied Device, forging apparatus, it is characterised in that forging apparatus includes upper die and lower die, upper mould is connected with hydrostatic forging hammer, and lower mould is connected With the earth, pulse current bringing device includes the pulse power and cable, and the positive pole of the pulse power is connected by cable with upper mould, arteries and veins The negative pole for rushing power supply is connected by cable with lower mould, and attemperator includes induction power supply, induction coil and cable, and induction coil leads to Cross cable to be connected with induction power supply, induction coil is parallel and close to being positioned on the outside of upper die and lower die and make by forging through sensing Coil.
The technical scheme that the utility model device is provided has following feature:
1st, the utility model device introduces electro plasticity process technology, when being processed there are some researches show, electro plasticity, the sense of current When identical with plastotype machine direction, electro plasticity effect is the most obvious, therefore the positive pole phase of upper mould and the pulse power is forged in the present apparatus Even, lower mould is connected with power cathode so that forging force during hot forging reduces, and adds by the machinability of forging, reduction processing During the energy that consumes.
2nd, in the utility model device by pulse current be passed through under the condition of high temperature by forging, high-temperature solid group can be caused Knitting is improved, and crystal grain is refined, so being passed through for pulse current can improve product quality.Metal is conducive to subsequently to add Work.
3rd, the utility model device be provided through electromagnetic induction heating technology realization attemperator, compared to it is traditional The processing mode of Repeat-heating, process time of the present apparatus after single heating is longer, and relatively conventional mode of heating, is used in addition Electromagnetic induction heating can more environmentally-friendly, low-carbon, energy-conservation.
Brief description of the drawings
Fig. 1 is the utility model device embodiment schematic diagram;
In accompanying drawing, the 1- pulse powers, mould under 2-, 3- is by forging, the upper moulds of 4-, 5- induction coils, 6- induction power supplies, 7- electricity Cable.
Embodiment
Illustrate the embodiment of the utility model device referring to the drawings.
Reference picture 1, it is parallel to put first according to by the geometry of forging (3) and the suitable induction coil of size selection (5) Be placed in the outside of mould (4) and lower mould (2) and to avoid producing influence to process, its should close to upper mould (4) and under Mould (2), induction coil (5) will be passed through during processing by forging (3).Secondly, adjusting the electrical parameter of the pulse power (1) mainly includes Frequency, pulsewidth and current value.Finally, hot forging processing is carried out, processing mode is identical with conventional processing mode.
