Abstract
The utility model discloses a high-temperature extrusion-forming device for a titanium-aluminum material, and relates to the extrusion-forming device. The high-temperature extrusion-forming device for the titanium-aluminum material comprises an extruding concave die, an extruding sheath, a sheath cover, a coil and a terrace die, wherein the extruding concave die is provided with a sheath chamber, a conical chamber and a material falling chamber communicated with one another along the vertical center from top to bottom; the extruding sheath is arranged in the sheath chamber; the sheath cover is arranged on the upper end face of the extruding sheath; the coil is sleeved over the outer sidewall of the extruding concave die; and the terrace die is arranged above the sheath chamber. The high-temperature extrusion-forming device disclosed by the utility model is used for high-temperature thermal extrusion formation of the titanium-aluminum material.
Description
Technical field
The utility model relates to a kind of extrusion molding apparatus, is specifically related to a kind of high temperature extrusion building mortion of titanium aluminum.
Background technology
Intermatallic Ti-Al compound has the high temperature resistant and antioxygenic property that density is little, specific strength is high, specific modulus is high and excellent, and the extrusion process shaping for titanium aluminum, requires the mode at warm deformations such as more than 1200 ℃ temperature employings conventionally, could carry out smoothly.Yet traditional Isothermal Hot extrusion process requires mold temperature identical with blank temperature, do not have at present suitable mold materials can meet the needs that carry out ausforming at high temperature like this.If adopt ordinary hot technological process of extruding, reduce mould and die preheating and actual work temperature, in extrusion process, high temperature blank is exceedingly fast to the heat transmission of low temperature mould, the problem such as make that high temperature blank rapid heat dissipation, blank temperature drop are large, resistance of deformation suddenly increases, mould damage is serious, the very difficult even blank of extrusion molding cannot be extruded.
Utility model content
The utility model provides a kind of high temperature extrusion building mortion of titanium aluminum for above-mentioned technical problem.
The high temperature extrusion building mortion of titanium aluminum of the present utility model comprises Extruding die, extruding jacket, jacket lid, coil and punch, Extruding die is provided with along vertical center jacket chamber, conical cavity and the blanking chamber communicating from top to bottom, extruding jacket is arranged in jacket chamber, jacket lid is arranged on the upper surface of extruding jacket, mounting coil is on the lateral wall of Extruding die, and punch is positioned at the top in jacket chamber.
The utlity model has following beneficial effect:
The utility model heats Extruding die by coil, and in the inner chamber of Extruding die and punch, increase the extruding jacket with heat insulation, power transmission and lubricating function, the extruding force that can extruding punch be applied by extruding jacket is transmitted to blank, can avoid again titanium aluminium blank to contact with the direct of Extruding die and punch, avoid thus the friction of titanium aluminium blank and Extruding die, and stop high temperature titanium aluminium blank to the heat radiation of Extruding die and punch, make titanium aluminium blank in extrusion process in the constant condition of high temperature of temperature substantially constant; Adopt the utility model to implement high warm extrusion to titanium aluminium blank, in extrusion process, the heat radiation of titanium aluminium blank is slow, resistance of deformation is little, mould is injury-free, extrusion molding is easy.
Accompanying drawing explanation
Fig. 1 is the main cutaway view of overall structure of the present utility model, the matched moulds figure before titanium aluminum extrusion molding; Fig. 2 is the main cutaway view of overall structure of the present utility model, the state diagram of titanium aluminum extrusion molding, and in figure, the direction of arrow is application of force direction.
The specific embodiment
The specific embodiment one: present embodiment is described in conjunction with Fig. 1, present embodiment comprises Extruding die 1, extruding jacket 2, jacket lid 3, coil 4 and punch 5, Extruding die 1 is provided with along vertical center jacket chamber 1-1, conical cavity 1-2 and the blanking chamber 1-3 communicating from top to bottom, extruding jacket 2 is arranged in the 1-1 of jacket chamber, jacket lid 3 is arranged on the upper surface of extruding jacket 2, coil 4 is sleeved on the lateral wall of Extruding die 1, and punch 5 is positioned at the top of jacket chamber 1-1.
The specific embodiment two: in conjunction with Fig. 1, present embodiment is described, the upper surface of the coil 4 of present embodiment is positioned on the upper surface of jacket lid 3.Other composition and annexation are identical with the specific embodiment one.
