Abstract
A supporting block of non-core electromagnetic fixture used for grinding the external slot ring of bearing is made of MoS2, Ni, graphite and bronze through proportionally mixing, die pressing,sintering, die pressing again, sintering again and post-treating.
Description
Technical field:
The present invention relates to the lathe worker tool technical field that is installed, a kind of Grinding Outer Ring Electromagnetic Coreless Clamp Using For Supporting Pad Preparing Process.
Background technology:
At present, the electric magnetic no-core grinding is mainly adopted in the grinding of bearing outer ring raceway groove, the electric magnetic no-core clamp adopts Wimet, nylon, fluoroplastics and the manufacturing of textolite material to be shaped as bar shaped or circular shape with rest pad more, wherein Hardmetal materials is processed, because of its hardness is big, processing is difficulty, and easy surface generation scuffing, colour band to lasso, must append and not be in the mood for the reconditioning operation together, increase production cost; Nylon, fluoroplastics and textolite rest pad, its working life is low.
Summary of the invention:
In order to solve scuffing and the colour band problem of a piece to workpiece, the invention provides the preparation technology of a kind of bearing outer ring raceway groove electric magnetic no-core clamp with rest pad, improve the working life of rest pad, reduce production costs.
Described bearing outer ring raceway groove electric magnetic no-core clamp rest pad preparation method adopts molybdenumdisulphide; Nickel; Graphite and bronze material:
Wherein: molybdenumdisulphide MOS
2: 1%-4%; Nickel: 3%-5%; Graphite C: 0.3%-1%; All the other are bronze (per-cent is weight ratio).
Its preparation technology who adopts is: raw material preparation → batch mixing → compacting → sintering → multiple pressure → resintering → aftertreatment.
Owing to adopted material and preparation technology as mentioned above, the present invention has following superiority:
The bearing outer ring raceway groove electric magnetic no-core clamp rest pad that the present invention adopts, its materials processing performance is good, no magnetic, lasso is not had scuffing, and wear resistance doubles above than textolite material, when grinding is used, improve the working accuracy of bearing, saved the centreless grinding operation one.
Material of the present invention is after tested: its physical and mechanical properties: hardness: HB40-60; Density: 6.4-7.0g/cm
3Ultimate compression strength: 59-78Mpa.
Its rest pad material and starting material average friction coefficient relatively are:
| Material | This rest pad | Nylon | Fluoroplastics | Textolite |
| Average friction coefficient μ | ????0.01 | ??0.04 | ??0.033 | ????0.035 |
Specific embodiment:
With Powdered molybdenumdisulphide (MOS
2): 1%; Nickel (Ni): 5%; Graphite (C): 1%; 6.63 bronze: 93%; Add Zinic stearas 1%, in the mixing machine of packing into, on mixer, mix, take out compound, take by weighing a certain amount of mixed powder, the shaping dies of packing into, moulding on pressing machine, the shaping base is packed in the sintering oven, and at 800 ℃ of following sintering, sintered blank is packed in the multiple pressing mold, the multiple pressure on pressing machine, multiple pressed compact carries out vacuum oil immersion and handles behind 810 ℃ of resinterings, can produce grinding outer ring raceway electric magnetic no-core clamp rest pad.
Claims (2)
