Description
Technical field
The utility model belongs to metal material processing equipment technical field, is specifically related to a kind of mould for school shape inside and outside titanium alloy member.
Background technology
Titanium alloy causes temperature-room type plasticity poor because of its crystal structure, and cold deformation difficulty, can not adopt iron hammer directly to knock the method for rectification, surface can be made to crack or formation of crack during the shape of component school, and therefore titanium alloy member school shape can only adopt the mode of heating school shape.Meanwhile, the elastic modelling quantity of titanium is 110250Mpa, and about being about the half of steel, therefore the screen resilience of titanium alloy is larger, and titanium alloy member school shape is more much more difficult than steel-casting, usually adopts thermomechanical school shape and thermal deformation school shape two kinds of modes.
The thermomechanical school shape of titanium alloy is loaded in chamber type electric resistance furnace by component to heat, temperature is at about 400 DEG C, temperature retention time was at 20 ~ 40 minutes, then the component heated is moved to rapidly on hydraulic press and fix, and apply suitable pressure, make to need the position of school shape that certain deformation occurs, to reach the object of school shape.Be transported to hydraulic press positioning school shape again, position fixing process thermal loss because component need first heat, affect school shape effect, and adopt hydraulic press school shape, component easily produces stress, must carry out stress relief annealing in time.
The thermal deformation school shape of titanium alloy component is put into school shape mould; and on mould, place the weight of enough weight; then they are placed in high-temperature vacuum furnace or protective atmosphere stove; be warming up to 900 DEG C ~ 950 DEG C; and be incubated 4 ~ 6 hours; under the Action of Gravity Field of patrix, component produces the deformation of creep, reaches the requirement of school shape.Because whole school shape process need carries out under vacuum or protective atmosphere, to equipment and site requirements higher, and need be placed in high temperature furnace by component, school shape mould and counterweight entirety during the shape of school, requisite space is comparatively large, and component school form quotient is low.
When heating-up temperature is lower than 600 DEG C, the thermal deformation school shape of titanium alloy member can be carried out in an atmosphere, to equipment and site requirements lower, large-scale, thin-walled, complex structure component school shape can be carried out, and the oxide layer that component surface produces is thinner, can remove at titanium alloy member finishing, without the need to increasing operation.
