Abstract
The utility model relates to a liquid-state mould forging magnesium alloy wheel hub mould which comprises an upper mould base and a lower mould base, wherein the bottom of the upper mould base and the upper part of the lower mould base are respectively provided with a central raised mould body and a concave mould fixedly; a ring pressing element is arranged at the outer side of the concave mould; and a ring protection locking mechanism is installed on the outer side of the central raised mould body. The liquid-state mould forging magnesium alloy wheel hub mould provided by the utility model has the beneficial effects that: through adopting a valve-type concave mould structure and matching with a raised mould structure, the subsequent machining quantity of the magnesium alloy wheel hub which is subjected to liquid forging is reduced greatly, the part of the upper part of the liquid forging element, on which shrinkage defects are easy to generate, are fed, and defects can be eliminated; the liquid-state mould forging magnesium alloy wheel hub mould is good for adopting a direct liquid-state forging method, an a vertical parting surface is adopted for the concave mould, thus a workpiece is convenient to be moulded; the machined magnesium is tiny in texture, has uniform and compact components and has high mechanical strength and performances; and under the condition of same appearance structure size, the liquid-state mould forging magnesium alloy parts have superior performances compared with the cast magnesium alloy parts.
Description
Technical field
The utility model relates to automotive hub manufacturing technology field, relates in particular to a kind of liquid forging magnesium alloy hub mould.
Background technology
Along with rising steadily and progressively raising that sustainable development requires of energy prices, the economy problems of motor vehicle fuel more and more causes people's extensive concern, and the economy of motor vehicle fuel and the design of automobile, manufacturing and use have substantial connection.In order to adapt to the light-weighted requirement of automobile; Some new materials constantly occur and have enlarged the scope of application; Marked change has also taken place in the application development trend of main material; For example: the application of traditional materials such as iron and steel, copper, lead, zinc increasess slowly, and is that the light metal material of representative is a dark horse with the magnesium alloy, is just constantly increasing with fast speeds and will more and more receive people's favor; Magnesium is because its good physical property, machining property, abundant reserves etc. are known as the most promising lightweight material in the industry.
For aluminium, magnesium alloy vehicle wheel; Mainly contain cast type and the formula of forging dual mode at present both at home and abroad, the traditional handicraft of magnesium alloy parts is compression casting, promptly molten metal liquid form with high speed and high pressure in the extremely short time; In the filling die cavity; Gas in the die cavity can not in time be discharged, owing to increased being involved in of gas in the molten metal at a high speed, makes the die casting internal porosity more serious simultaneously; If adopt the heat treatment bubble to break out out, this is that die casting can not be put forward reasons of high performance through heat treatment; Simultaneously, pressure is to be applied on the metal bath surface by the injection effect, and the time is short again, therefore also can not avoid shrinkage cavity, casting flaw such as loose fully.Casting ingot is handled, is swaged, technology such as rolling if adopt, then behind die-forging forming, by swage, the manufacturing of rolling mill practice completion wheel; Obviously; The magnesium alloy vehicle wheel that this method is processed has good organization and mechanical performance, but its complex process, required device category is many, investment is big, production cost is high; And swage to having the lower magnesium alloy of close-packed hexagonal lattice plasticity, having increased, the difficulty of rolling mill practice.Therefore, to above aspect, need reasonably improve the existing mold technology.
The utility model content
To above defective, the utility model a kind of high strength is provided and in light weight, thermal conductivity is good, dimensional stability is high, help reducing the liquid forging magnesium alloy hub mould of following process amount, to solve many deficiencies of prior art.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of liquid forging magnesium alloy hub mould; Comprise upper bolster and die shoe; Said upper bolster bottom fixedly installs center body of punch, die respectively with die shoe top, die arranged outside one circle compressing member wherein, and the retaining ring retaining mechanism is installed in the body of punch outside, center wherein; The position of said die is in the periphery with body of punch corresponding position, center, the peripheral lifting assembly of installing of said upper bolster.
The beneficial effect of the described liquid forging magnesium alloy hub of the utility model mould is: the die structure through adopting split-type also cooperates punch structure; The following process amount that makes liquid forge magnesium alloy hub significantly reduces, and the position that makes liquid forging top be easy to produce shrink defects obtains feeding and can eliminate defective; Help taking direct liquid forging method and die to take the vertical-parting face, so that the workpiece depanning; That the magnesium alloy of being processed is organized is thinner, composition more evenly, finer and close, have higher mechanical strength and performance, under the situation of identical appearance physical dimension, the magnesium alloy parts of liquid forging has better performance than cast magnesium alloy part.
Description of drawings
According to accompanying drawing the utility model is done further explain below.
Fig. 1 is the structural representation of the said liquid forging magnesium alloy hub of the utility model embodiment mould.
Among the figure:
1, upper bolster; 2, die shoe; 3, compressing member; 4, center body of punch; 5, die; 6, retaining ring retaining mechanism; 7, lifting assembly.
The specific embodiment
As shown in Figure 1; The described liquid forging magnesium alloy hub of the utility model embodiment mould; Comprise upper bolster 1 and die shoe 2, the position that said upper bolster 1 bottom and die shoe 2 tops fixedly install center body of punch 4, die 5 and this die 5 respectively is arranged at the periphery with center body of punch 4 corresponding positions; Die 5 arranged outside one circle compressing member 3 wherein, retaining ring retaining mechanism 6 is installed in center body of punch 4 outsides wherein, is positioned at the upper bolster 1 peripheral lifting assembly 7 of installing.When work, behind casting metal in the die 5, patrix is descending; Compressing member 3 forms locked mode, with rear center's body of punch 4 press moldings, after the pressurize; Center body of punch 4 is up with patrix, and compressing member 3 still compresses so that the punch demoulding, and its thrust should be greater than the punch knockout press; Last lifting assembly 7 drivening piece compressing members 3 are up, and mould separately takes out workpiece.
The described liquid forging magnesium alloy hub of above the utility model embodiment mould, liquid forging all afford etc. to static pressure the metal of ot-yet-hardened in forming process from start to finish; Also be attended by plastic deformation; Be to carry out solidification and crystallization under pressure, so crystal grain is tiny, dense structure; Shrinkage cavity, loose generation can be avoided fully, the material mechanical performance index can be significantly improved.Set wheel hub surface of the work gauge must leave certain machining allowance, therefore can be on the part thickness size the monolateral 0.5mm that places, and get 1.5 ° of pattern drafts.
Above embodiment is the more preferably specific embodiment a kind of of the utility model, and common variation that those skilled in the art carry out in present technique scheme scope and replacement should be included in the protection domain of the utility model.
