Description
Technical field
The utility model relates to a kind of bearing shell squeezing shaping mould, particularly a kind of mould of bearing shell bore area precision truing, belongs to the precision plastic forming technical field of metal material.
Background technology
Bearing shell is parts with frication pair, and the effects on surface roughness requires high during work.At present generally adopt the mode of grinding to process to the processing of bearing shell because the multiplex Cu alloy material of bearing shell makes, when require its surface smoothness higher, when requiring its surface roughness≤Ra0.4 μ m, adopt existing grinding attachment just to be difficult to meet the demands.Therefore existing grinding attachment still can not satisfy the needs of use.
Summary of the invention
The purpose of this utility model is: provide a kind of and can process the bearing shell squeezing shaping mould that surface smoothness is higher and simple in structure, easy to operate, cost of manufacture is cheap, to overcome the deficiencies in the prior art.
The technical solution of the utility model is to consist of like this: a kind of bearing shell squeezing shaping mould of the present utility model is: this mould is comprised of punch, die and top cover, punch is for being comprised of footstalk and the diameter working face cylinder greater than the footstalk diameter, in die, be provided be used to the through hole that processed columnar bearing shell is installed, top cover is installed in the through hole of die movingly, the working face cylinder of punch can inject in the through hole of die, and the diameter of the working face cylinder of punch is greater than the diameter of bore of processed bearing shell.
On be set forth in the diameter of working face cylinder of punch greater than the diameter of bore 0.2～0.3mm of bearing shell.
The through-hole diameter of the die of above-mentioned installation bearing shell is equal to or less than the outside diameter of bearing shell.
The through-hole diameter of above-mentioned die is less than the outside diameter 0.02～0.05mm of bearing shell.
The diameter of bore of above-mentioned top cover is greater than the diameter of bore of bearing shell.
Front end at the working face cylinder of above-mentioned punch is provided with the guiding conical surface.
The height sum of above-mentioned top cover and bearing shell is less than the height of die.
Owing to having adopted technique scheme, the utility model utilization cold plastic deformation principle has realized the mirror finish to the bearing shell bore area.Critical piece effect of the present utility model is as follows: the shaping working face cylinder of punch is arc structure, and its outside diameter is than the large 0.2～0.3mm of bearing shell diameter of bore, to guarantee the shaping magnitude of interference.The bore area of die is the bearing shell locating surface and micro-pretension arranged, and top cover is made axial restraint to bearing shell, and can bearing shell be taken out from die by top cover after processing.Its operation principle be the bearing shell with the need shaping be pressed into gently die fixing after, punch is moved along the relative bearing shell of axis direction, because there are certain magnitude of interference in working face cylinder and the bearing shell bore area of punch, force the bearing shell surface to produce the plastic extruding deformation of trace, thereby reach the effect of surperficial shaping.Use proof through reality: the utility model can realize minimum wall thickness (MINI W.) 2～3mm, and diameter of bore is that the bearing shell bore area of 30～120mm carries out shaping; The roughness on its machining and shaping surface can reach below the Ra0.1 μ m.Therefore, the utility model compared with prior art, the utility model has advantages of that not only the bearing shell that can process specular surface, the piece surface fineness that processes are higher, but also has the advantages such as simple in structure, easy to operate, that reliability is high, cost of manufacture is cheap, service life is long.

The specific embodiment
Embodiment of the present utility model: when the bore area to the bearing shell 4 of machine-shaping carries out shaping, can adopt a kind of bearing shell squeezing shaping mould of the present utility model that it is carried out shaping, the utility model is constructed according to the method for following a kind of bearing shell bore area precision truing, the method be first by existing processing mode with bearing shell 4 machine-shapings, with bearing shell 4 machine-shaping the time, should reserve the allowance of 0.2～0.3mm with bearing shell 4 machine-shapings by the requirement of the interior hole dimension of bearing shell to be processed 4, then bearing shell 4 is put into a through hole that is provided with the die 2 of through hole, in the through hole of die 2, place in advance simultaneously a top cover 3, make 3 pairs of bearing shells 4 of top cover make axial location, cooperating for movingly of the through hole of top cover 3 and die 2, the cooperating for excessively cooperating of the through hole of bearing shell 4 and die 2; Then make a punch 1 that is provided with working face cylinder 1.2, make the diameter of working face cylinder 1.2 of this punch 1 greater than the diameter of bore 0.2～0.3mm of processed in type bearing shell 4; Then after the working face cylinder 1.2 of punch 1 being put into the through hole of die 2, punch 1 relative bearing shell 4 is moved, can push by 1.2 pairs of bearing shell 4 bore areas of working face cylinder of punch 1 like this, force bearing shell 4 surfaces to produce the plastic extruding deformation of trace, thereby reach the purpose of surface accurate shaping.
When making the relative bearing shell 4 of punch 1 do motion, can adopt the mode of artificial or mechanical device to make punch 1 along relative bearing shell 4 moving linearlies of axis direction above-mentioned; Also can adopt the mode of artificial or mechanical device to make punch 1 punch 1 be rotated along axis direction relative to bearing shell 4 moving linearly time around its axis.
When adopting mechanical device to make punch 1 relative bearing shell 4 do motion, can adopt the mechanical devices such as hydraulic test of the prior art, pressing equipment, bench drill, vertical drill or radial drilling machine.
