Description
Technical field
The utility model belongs to the variable displacement type field of mechanical technique, is specifically related to a kind of precise punching die of machining oil clearance bevel of thrust bearing of turbocharger.
Background technology
Turbocharger is the vitals that improves power of IC engine, reduction consumption rate of fired oil, improves discharging, and day by day short at the whole world energy, that environment goes from bad to worse today, exhaust gas turbocharge has become the only way which must be passed of internal combustion engine development.Thrust bearing is the vital part in the turbocharger, it is bearing the axial thrust of booster, the axially amount of scurrying of control booster, the oil clearance bevel crudy quality of thrust bearing both ends of the surface directly influences the reliability of bearing capacity, wearability and the turbocharger of thrust bearing.
The oil clearance bevel structure of thrust bearing both ends of the surface is spiral at present, has quarter, six equal portions, eight equal portions not to wait usually, and forming technique has five-shaft numerical control milling machine milling method, special equipment form copying, lathe to hang leading screw processing method etc.Five-shaft numerical control milling machine milling method working (machining) efficiency is low, processes one and needs 1 hour man-hour, cost height.Special equipment form copying and lathe extension leading screw processing method working (machining) efficiency are lower, process one and need 10 minutes man-hours, occur the knife phenomenon easily, plane and inclined-plane intersection transition are not slick and sly, the step that 0.02-0.05mm is arranged, the oil clearance bevel machined surface quality is poor, and roughness has only Ra6.3 μ m; The inclined-plane dimensional uniformity is poor, and these three kinds of processing methods can not satisfy requirements of mass production.
Summary of the invention
The utility model is exactly the shortcoming that exists in the above-mentioned prior art, a kind of precise punching die of machining oil clearance bevel of thrust bearing of turbocharger is provided, it is lower to solve the cost height, the working (machining) efficiency that exist in the above-mentioned prior art, the knife phenomenon appears easily, plane and inclined-plane intersection transition are not slick and sly, the oil clearance bevel machined surface quality is poor, and the inclined-plane dimensional uniformity is poor, and these three kinds of processing methods can not satisfy problems such as requirements of mass production.
The utility model is by the following technical solutions: the precise punching die of machining oil clearance bevel of thrust bearing of turbocharger, comprise die shank 1, guide pillar 2, guide pin bushing 3, cope match-plate pattern 4, lower bolster 5, last punch 6, lower punch 7, upper bolster 8, die shoe 9, push rod 10, limiting plate 11, mandrel 12, spring 13, alignment pin 14, die shank 1 and cope match-plate pattern 4 are connected by screw, cope match-plate pattern 4 and upper bolster 8, lower bolster 5 and die shoe 9 are connected by screw, upper bolster 8 is connected with last punch 6 interference, upper bolster 8 has limiting plate 11, limiting plate 11 has die shoe 9, die shoe 9 is connected with lower punch 7 interference, die shoe 9 right sides are provided with alignment pin 14, die shoe 9 bottoms and lower bolster 5 are connected by screw, lower bolster is provided with spring 13 for 5 li, spring 13 is provided with mandrel 12, mandrel 12 is provided with push rod 10, and workpiece is connected with lower punch 7 with alignment pin 14 by mandrel 12, and lower bolster 5 right sides are connected with the lower end of guide pillar 2, guide pillar 2 outsides are provided with guide pin bushing 3, and the upper end of guide pin bushing 3 is connected with cope match-plate pattern 4.Last punch 6, lower punch 7 end faces are provided with quarter projection screw inclined plane, and described inclined-plane drop is 0.08-0.09mm.
The utility model compared with prior art has following beneficial effect: easy and simple to handle, do not need professional operative employee; Production efficiency increases substantially, and only need 15 seconds every process time, and processing cost descends significantly; Plane and inclined-plane intersection transition slyness; Machined surface quality height, roughness can reach Ra0.8 μ m; The oil clearance bevel dimensional uniformity is good, satisfies large batch of production requirement.
