Abstract
The present invention relates to a mirror processing method for a working surface of a mechanical part, which belongs to the technical field of mechanical process; the present invention has the method that at least 0.02mm of extrusion allowance is reserved under the condition of ensuring the roughness of a processed bottom surface of a part; the part is cleaned before extruded; the impurities of a processing bottom surface are blown by compressed air; a mother body made of material of which the hardness and the roughness are larger than those of the bottom surface of a processed part is slowly extruded in a uniform speed mode by hydraulic force or mechanical force for passing through the processed bottom surface; thereby, the inner wall of a cylinder and the outer surface of a piston are changed into mirror surfaces, the breaking-in period of an engine is greatly shortened or is not required, the operation of the engine is smooth, and the noise is small; the gas leakage rate in the breaking-in period is greatly reduced; the oil consumption is low, the discharge is less, the energy saving and environment protection requirements are conformed, and the service life can be greatly extended; the present invention is suitable for the manufacture industry and the maintenance industry of automobiles and relevant motor vehicles. The processing method is also suitable for parts made of wood and plastics.
Description
Technical field
Suitable and a kind of mirror processing method for working surface of mechanical part of the present invention belongs to the Machining Technology field that component of machine improves working face accuracy, hardness, density and abrasion resistance.
Background technology
The working face of some components of machine, because of the needs that cooperatively interact, requirement has technical performance indexs such as higher accuracy, hardness, as cylinder and piston, existing processing to cylinder bearing face is to ward off cylinder and then grinding earlier for a long time, and the result of this processing technology is that the roughness of working face is not very high, and the channels and collaterals and the piston ring direction of motion are inconsistent, cause product use in time running-in period long, leak rate is high, oil consumption is big, noise is big and the discharging height.
Summary of the invention
The objective of the invention is at the technical performance indexs such as machining accuracy of the existing processing technology existence of some component of machine working faces undesirable, time running-in period was long during the product that forms used, leak rate is high, oil consumption is big, noise is big and discharge high deficiency, technical indicators such as can improving machining accuracy is provided, thereby greatly improves a kind of mirror processing method for working surface of mechanical part of product technology performance.
The objective of the invention is to be achieved through the following technical solutions, a kind of mirror processing method for working surface of mechanical part, its described method is under the situation that guarantees parts processing bottom surface roughness, leave the extruding allowance of 0.02-0.1mm, clean before the extruding, and blow most processing bottom surface impurity with compressed air, use the parent of making much larger than processed parts bottom surface hardness and roughness material slowly, at the uniform velocity to be pressed through the processing bottom surface, add cooling, lubricating fluid in the extrusion process through hydraulic pressure or mechanical force.
The invention discloses a kind of mirror processing method for working surface of mechanical part, use the parent of making much larger than processed parts bottom surface hardness and roughness material, make parent slow through hydraulic pressure or mechanical force, at the uniform velocity be pressed through processed parts bottom surface, make as cylinder inner wall, outer surface of piston becomes minute surface, engine is shortened running-in period greatly or need not running-in period, the more important thing is because highly accurate, face height is smooth like minute surface, frictional resistance is littler, make engine running more steady, noise is littler, also can dwindle the fit clearance of cylinder and piston, to reduce oil consumption, reduce discharging, because cylinder inner wall has become minute surface, make piston ring cooperate better with it, significantly reduced the leak rate in running-in period, make that also oil consumption is lower, discharging still less, meet energy conservation and environment protection, in addition, owing to improved the compactness extent and the hardness of friction surface, can also increase the service life greatly, be applicable to the manufacturing of automobile and relevant motor vehicle, maintenance industry, processing method of the present invention also is applicable to the parts of timber and plastic material.
The specific embodiment
Further specify the present invention in conjunction with the embodiments, disclosed by the invention is a kind of mirror processing method for working surface of mechanical part, be to ward off cylinder earlier as cylinder to existing, and then the improvement of the traditional handicraft of grinding, method is: under the situation that guarantees parts processing bottom surface roughness, leave the extruding allowance of 0.02mm at least, before the extruding processing bottom surface is cleaned, removal of impurities, removal of impurities is to blow most processing bottom surface impurity with compressed air, use the parent of making much larger than processed parts bottom surface hardness and roughness material slow through hydraulic pressure or mechanical force, at the uniform velocity be pressed through the processing bottom surface, add cooling in the extrusion process, lubricating fluid.When working face is circular hole, the pinball that parent can be made with carbide alloy or steel alloy class material, its diameter is than working face slightly larger in diameter; When working face is periphery, the casement that parent can be made with carbide alloy or steel alloy class material, the internal diameter of casement is more smaller than working face diameter; Cooling, lubricating fluid can be used the mixed liquor of kerosene, lubricating oil or kerosene and lubricating oil.
Claims (6)
1, a kind of mirror processing method for working surface of mechanical part, it is characterized in that described method is to guarantee processing bottom surface roughness and leave under the extruding allowance situation at processed parts, clean earlier and removal of impurities, use the parent of making much larger than processed parts bottom surface hardness and roughness material slowly, at the uniform velocity to be pressed through the processing bottom surface, add cooling, lubricating fluid in the extrusion process through hydraulic pressure or mechanical force.
