Horizontal type device for reheating semi-solid metal blank material

Abstract

The invention relates to a horizontal type device for reheating a semi-solid metal blank material, which comprises an induction heating power supply, an induction heating mechanism, and a blank material carrying mechanism, and is provided with five stations, such as at least three material heating stations, a material placing station and a material discharging station, wherein the induction heating mechanism adopts three sections of induction heating coils which are separately and horizontally arranged, and all the induction heating coils are mutually electrically communicated and arranged on the three material heating stations respectively; the blank material carrying mechanism comprises a feed mechanism and a blank material transporting device; the blank material transporting device is a delivering device processing in front of each station; and the feed mechanism is positioned in front of each induction heating coil. The induction heating three-section heating mode is selected to make the heating of the blank material and the distribution of the temperature field more even and reasonable. The horizontal structure is adopted, the blank material cannot collapse or discharge fluid, and the blank material transportation is simple and convenient because of a large contact surface between the blank material and a supporting part. The blank material is allowed to have a higher liquid phase fraction, which is convenient for the thixotropic forming of more complicated parts.

Description

technical field [0001] The invention belongs to the technical field of metal semi-solid processing, and in particular relates to a secondary heating device for a semi-solid metal blank. Background technique [0002] Metal semi-solid processing technology is a new processing and forming method between traditional solid processing technology (such as rolling, extrusion, forging, etc.) and liquid forming technology (such as casting, etc.). Its core technical features include: 1) The forming temperature is between the solid-liquidus temperature; 2) The grain shape is different from the dendritic grain shape in the general solidification structure, but is non-dendritic and nearly spherical the grain shape. Due to the above characteristics, semi-solid processing technology has the advantages of less casting defects, low porosity, easy processing and forming, and high mold life. These advantages make semi-solid processing technology have considerable competitive advantages in ter...

Problems solved by technology

For a semi-solid billet with a small aspect ratio, the vertical heating device can also be used to heat the billet to a semi-solid state for forming, and defects such as collapse and "elephant foot" will not occur, but for semi-solid billets with a large height-to-diameter ratio For solid billet, if a vertical device is used, the shape of the billet will change in the later stage of heating, forming an "elephant foot". The billet will collapse and flow during the transfer process, which will affect the heating effect of the billet and the transportation, operation and Therefore, the liquid phase fraction of the billet cannot be very high, and it is difficult to form complex parts, especially for semi-solid billets with a large aspect ratio

In addition, for the semi-solid secondary heating vertical device, the mechanical transmission method used is also very complicated, often including complex mechanisms such as lifting and rotating of the transmission mechanism, resulting in a large and complicated device and high investment costs
