Abstract
Automobile wheel semisolid rheoforming slurrying equipment comprises a periphery electromagnetic stirrer, resistive heaters, a center electromagnetic stirrer, a graphite pipe, a graphite pipe lifting driving motor and an electric control cabinet. The periphery electromagnetic stirrer is installed in the middle of the outer wall of a cone frustum slurrying container, the center electromagnetic stirrer is installed in the graphite pipe which can be immerged in semisolid slurry in the cone frustum slurrying container, the resistive heaters are evenly distributed on the wall of the cone frustum slurrying container, the periphery electromagnetic stirrer, the center electromagnetic stirrer, the graphite pipe lifting driving motor and the resistive heaters are connected with the electric control cabinet through wires, and the distance between the graphite pipe and the bottom of a crucible is 100-120mm. A combined electromagnetic stirring device effectively solves the problem that due to the fact that the size of a slurrying chamber of traditional electromagnetic stirring equipment is large, center partial stirring is uneven.
Description
Technical field
The present invention relates to the semi-soild-state technology field, relate in particular to a kind of automotive wheel semi-solid rheological molding pulping equipment.
Background technology
Semisolid refers in the alloy two-phase state that not only has spherical solid phase but also have the fluid liquid phase.Semi-solid state forming technique be early 1970s Massachusetts Institute Technology M.C.Flemings professor and the new method of a kind of metal forming of at first proposing of doctor D.B.Spencer, it is that metal or alloy is imposed violent stirring action to it when solidus and liquidus temperature are interval, fully broken dendritic nascent solid phase, obtain a kind of mixed slurry of solid-liquid of even certain spherical nascent solid phase that suspending, a kind of new technology of processing then.Compare with common extrusion process, adopt semi-solid-state shaping processes aluminum alloy automobile wheel to have following advantage: to compare with liquid cast, there is more rich solid phase particle in semisolid, in process of setting, form gritty texture's form of dispersing, avoid the conventional cast formation of the thick crystalline substance of formation easily, improved the interior quality of foundry goods; The semisolid product surface is free of pinholes almost, generally casts the shrinkage cavity defect at the common heavv section position of wheel rim, and is comparatively rare in the wheel of semi-solid-state shaping; Strength of materials height can effectively be implemented lightweight; Forming temperature is lower than the liquid pouring temperature, has reduced the thermal shock to die casting, has prolonged die life; The big spoke degree of stock utilization improves, and product allowance reduces, and can realize the near-net-shape of product; Alleviated the shaping drag, mao mao's base of the complex parts that can be shaped; Quality is higher than low pressure casting, and price is lower than forging.Just because of above outstanding various advantages, the semi-solid metal forming technology is described as " the green industrial technology that 21 century is the most promising ".
The semi-solid alloy forming technique is divided into rheological molding and thixotropic forming two big classes usually.No matter be rheological molding or thixotropic forming, prepare tiny, etc. the semi solid slurry of axle be part most crucial in the semi-soild-state technology.The preparation method of semi solid slurry mainly contains electromagnetic stirring method, mechanical mixing method, near liquidus casting, is injected into long-pending method etc. at present; Though mechanical mixing method is a kind of method that occurs the earliest, because low, the agitating device loss of efficient is too big, the existence of problem such as pollution metal easily, therefore there is not the prospect of industrial applications; The near liquidus casting requires pouring temperature very near liquidus temperature, and technology controlling and process is very difficult, so operation easier is very big; Be injected into long-pending method and can only prepare smaller parts, and preparation cost is very high; And electromagnetic stirring method is owing to noncontact, the method that various advantages is considered to have most industrial prospect such as can accurately design always, but because the existence of the Kelvin effect of electromagnetic agitation, electromagnetic agitation is the outside that is applied in pulping chamber, not only make the semisolid slurrying time long, efficient is low, and makes the stirring of pulping chamber central part and limit portion inhomogeneous; Therefore press for a kind of equipment that improves slurrying efficient of seeking in the industry.
Summary of the invention
The objective of the invention is for solving the deficiency of above-mentioned pulp preparation, provide a kind of slurrying efficient Gao Bingke to impel the pulping equipment of slurry homogenising, a kind of automotive wheel semi-solid rheological molding pulping equipment specifically is provided.
Realize that above purpose technical scheme is, this equipment comprises peripheral magnetic stirrer, resistive heater, center magnetic stirrer, graphite-pipe, graphite-pipe lifting CD-ROM drive motor, electrical control cubicles; Peripheral magnetic stirrer is installed in the outer wall middle part of frustum of a cone mash vessel, the center magnetic stirrer is installed in the graphite-pipe, graphite-pipe can immerse the centre of semi solid slurry in the frustum of a cone mash vessel by graphite-pipe lifting CD-ROM drive motor, and resistive heater is evenly distributed on the frustum of a cone mash vessel wall; Peripheral magnetic stirrer, center magnetic stirrer, graphite-pipe lifting CD-ROM drive motor, resistive heater all are connected with electrical control cubicles by lead, and graphite-pipe is apart from crucible bottom 100～120mm.The composite electromagnetic agitating device efficiently solves traditional electromagnetic stirring equipment because the pulping chamber volume is big, the inhomogeneous phenomenon of the local stirring in center, guarantee under lower degree of supercooling, to realize the forming core crystallization simultaneously of whole melt, thereby obtain uniform semi solid slurry, the component segregation phenomenon is reduced greatly.
