Description
Technical field
The utility model belongs to metal drawing deformation techniques field, especially about a kind of bimetallic forced feed lubrication mold mechanism.
Background technology
Current known metal drawing deformation mould is comprised of inlet region, workspace (claiming again compressional zone), shaping area, outlet area etc.; Lubricant medium during metal drawing deformation (lubricating oil, lubricant, lubricated matter) is conventionally attached to metal surface and enters workspace via inlet region, forms lubricating film metal surface is lubricated, and reduces the frictional force of metal surface and mould inner wall.But the gap during due to metal drawing deformation between mould and metal is very little, and lubricant medium is difficult to enter into workspace, make lubricating film carry out enough lubricating to metal surface, cause drawing deformation mould to damage, by the metal material surface of drawing, easily pulled.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of bimetallic forced feed lubrication mold mechanism of forced feed lubrication mould, is that metal drawing completes deformation process via forced feed lubrication mold mechanism.
The technical solution of the utility model is achieved in the following ways: a kind of bimetallic forced feed lubrication mold mechanism, comprise mold base and core rod, in mold base, be provided with the endoporus communicating with front seam, rear seam, core rod is comprised of mould and booster set, it is characterized in that: described core rod is located in mold base cavity by flange bolt fastening on mold base, and spacing by front seam and rear seam.
Described core rod is comprised of the mould of front end and the booster set of rear end, and mould is comprised of inlet region, workspace, shaping area, outlet area, and the inlet region of mould, outlet area and front seam form 45o angle, workspace with by lashing wire, belonged to and form 5-60o angle.
The front end of described booster set is anallobar, and anallobar geometry is definite according to the shape of drawing metal, and the volume of anallobar and the pressure of lubricant medium are inversely proportional to; The rear end of booster set is guide hole, and guide hole geometry is according to being determined by the shape of drawing metal, guide hole with by the gap of drawing metal and lubricant medium pressure, be inversely proportional to.
The center of described mould, anallobar and guide hole in the same horizontal line.
The geometry of described anallobar is horn-like.
The geometry of described guide hole is circular hole.
Described mold base below is also provided with lubricant medium box.
The utility model, metal drawing completes deformation process via forced feed lubrication mold mechanism.Metal surface does not contact in mold work district with mould inner wall, and frictional force during metal drawing levels off to zero, thereby significantly improves the process conditions of metal drawing deformation, improves by a relatively large margin the surface quality of metal drawing deformation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 mold base, 2 core rods, 3 moulds, 4 booster sets, 5 drawing metals, 6 anallobars, 7 guide holes, 8 front seams, 9 rear seams, 10 flange bolts, 11 outlet areas, 12 workspaces.
The specific embodiment
A kind of bimetallic forced feed lubrication mold mechanism, comprise mold base 1 and core rod 2, in mold base 1, be provided with the endoporus that front seam 8, rear seam 9 communicate, core rod 2 is comprised of mould 3 and booster set 4, core rod 2 is located in mold base 1 cavity and is fastened on mold base 1 by flange bolt 10, and spacing by front seam 8 and rear seam 9.Core rod 2 is comprised of the mould 3 of front end and the booster set 4 of rear end, and mould is comprised of inlet region, workspace, shaping area, outlet area, and the inlet region of mould 3, outlet area 11 forms 45o angles with front seam 8, workspace 12 with by lashing wire, belonged to and form 5-60o angle.The front end of booster set 4 is anallobar 6, and anallobar 6 geometries are definite according to the shape of drawing metal 5, and the volume of anallobar 6 and the pressure of lubricant medium are inversely proportional to; The rear end of booster set 4 is guide hole 7, and guide hole 7 geometries are according to being determined by the shape of drawing metal 5, guide hole 7 with by the gap of drawing metal 5 and lubricant medium pressure, be inversely proportional to; The center of mould 3, anallobar 6 and guide hole 7 in the same horizontal line.Anallobar 6 geometries are because of different by the shape of drawing metal 5: when as round in form of metal, anallobar is horn-like, anallobar 6 restricted volume are in lubricant medium physical property (lubricating oil, lubricant, lubricated matter), and anallobar 6 volumes and lubricant medium pressure are inversely proportional to; The interior rear end of booster set 4 is guide hole 7, guide hole 7 geometries are because of by the shape of drawing metal 5 different when as round in form of metal (guide hole be circular hole), guide hole 7 with by the gap of drawing metal 5, be limited to lubricant medium physical property (lubricating oil, lubricant, lubricated matter), guide hole 7 with by the gap of drawing metal 5 and lubricant medium pressure, be inversely proportional to; The core rod 2 of described forced feed lubrication mold mechanism, the anallobar 6 in its mould 3, booster set 4 and the center of guide hole 7 are in the same horizontal line.Mold base 1 below is provided with lubricant medium box, and in box, lubricant medium thickness is greater than by drawing outer metallic surface (in drawing metal dip lubrication medium), and lubricant medium can manually add also and can automatically be added by pump system.
When the operation principle of forced feed lubrication mold mechanism is metal high speed drawing, lubricant medium passes through booster set cavity with certain viscosity/granularity, when initial, small part lubricant medium is with being entered mould by drawing metal, most of lubricant medium accumulates in the anallobar of establishing in booster set cavity, anallobar geometry is because of by the shape of drawing metal different when as round in form of metal (anallobar be horn-like), lubricant medium forms normal pressure (0.15～0.3MPa) after anallobar gathers, in metal continuous drawing process, lubricant medium is pressed between metal and mould under pressure, make the thicker oil film of formation between metal surface and mould inner wall, under oil film action, metal surface does not contact in mold work district with mould inner wall, frictional force during metal drawing levels off to zero, thereby significantly improve the process conditions of metal drawing deformation, improve by a relatively large margin the surface quality of metal drawing deformation.
