Description

A kind of school shape mould of modifiable titanium alloy member position location
Technical field
The utility model belongs to metal material processing equipment technical field, is specifically related to a kind of school shape mould of modifiable titanium alloy member position location.
Background technology
Titanium alloy causes temperature-room type plasticity poor because of its crystal structure, cold deformation difficulty, can not adopt during the shape of component school knock, the method for the gagging such as extruding, surface can be made to crack or formation of crack, 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 part, 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.
The mode that school shape mould adopts bottom fixing usually, but for the many boss in bottom, curved surface or abnormally-structured, bottom is fixedly difficult to realize, and limits school shape mold use, and for large-scale component, only fixes by bottom, is difficult to ensure that component is firm.
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.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the utility model provides a kind of school shape mould of modifiable titanium alloy member position location, under atmospheric environment, interior pressure school shape can be carried out to component, and meet the school shape requirement of the titanium alloy member of thin-walled, large scale or contour structures complexity.
The technical solution of the utility model is achieved in that
A school shape mould for modifiable titanium alloy member position location, comprises base, frame and shape rectifying mechanism;
Described frame is arranged on base, comprises front door frame and rear door frame, and front door frame and rear door frame are the gate framework be made up of column and crossbeam, and frame is provided with shape rectifying mechanism;
Described shape rectifying mechanism comprises school shape fastener, school shape fastener is provided with multiple can along the school shape part perpendicular to school shape fastener direction movement; Column is provided with bolt slot, and school shape fastener is arranged in pairs, and the left and right sides being bolted to front door frame and rear door frame by matching with bolt slot;
It is two right that the quantity of described school shape fastener is at least.
Wherein, preferably, described school shape part comprises shank of bolt and jacking block, and jacking block is arranged on the front end of shank of bolt, for titanium alloy member surface also transmission of pressure of fitting, described school shape fastener is provided with the bolt hole matched with shank of bolt.
Wherein, preferably, described jacking block is block or cylindric, assembles with the form of nut and described shank of bolt.
Wherein, preferably, described column and described school shape fastener are respectively arranged with scale.
Advantage of the present utility model and beneficial effect are:
1, the utility model structure is simple, easy to assembly, can meet the titanium alloy member school shape requirement of contour structures complexity;
2, the utility model can carry out interior pressure school shape to component under atmospheric environment, greatly reduces the percent defective of titanium alloy member, saves production cost.
3, the fixed position of the utility model adjustable component, is not limited to the mode that bottom surface is fixing, can meets the fixing requirement of curved surface or baroque special-shaped titanium alloy member.
