Background technology
CN101644308A, title " a kind of chain hinge pin and manufacture method thereof ", successively through cutting print, punching, cut-out, 2/4 take all of, 3/4 take all of, 4/4 take all of and full circle processing, and the jointed chain hinge pin of band obtaining rolling after intensive treatment, surface finishing and cleaning, this bearing pin is hollow structure, and seam crossing has at least one oil permeable hole.Its weak point: heat-resisting, wear-resisting, anti-oxidant, corrosion-resistant.
Summary of the invention
Purpose of design: avoid the weak point in background technology, if one has heat-resisting, wear-resisting, anti-oxidant, corrosion resistant aluminising chain hinge pin and preparation method.
Design: in order to realize above-mentioned purpose of design.Chain hinge pin workpiece surface adopts the technological design of metallic cementation thermo-chemical treatment, is technical characteristics of the present invention.The object of such design is: infiltrated by metallic atom in the superficial layer of steel, and it can be the superficial layer alloying making bearing pin, makes bearing pin surface of the work have the characteristic of some steel alloy, special steel, as heat-resisting, wear-resisting, anti-oxidant, corrosion-resistant etc.The present invention adopts aluminising to carry out chemical heat treatment process in chain hinge pin manufacture process, aluminum metal atom is made to infiltrate in bearing pin metal works top layer, be placed on containing infiltrating in the penetration enhancer of aluminum metal element by bearing pin, be heated to uniform temperature, after keeping appropriate time, the active atomic of the infiltration metallic element that penetration enhancer thermal decomposition produces just is adsorbed to bearing pin surface of the work, and diffuses into bearing pin workpiece surface, thus changes chemical composition, the structure and properties of bearing pin workpiece surface.
Technical scheme 1: a kind of aluminising chain hinge pin, chain hinge pin is GCr15 bearing pin and GCr15 bearing pin superficial layer is metallic cementation layer.
Technical scheme 2: a kind of preparation method of aluminising chain hinge pin, its feature: (1) GCr15 material makes bearing pin workpiece blank, the bearing pin workpiece then cutting required; (2) centreless grinding process equipment is adopted to process the bearing pin workpiece in above-mentioned (1); (3) adopt metallic cementation chemical heat treatment process, metallic cementation thermo-chemical treatment is carried out to the bearing pin in above-mentioned (2); (4) Q-tempering technique carries out Quench and temper process to the bearing pin in above-mentioned (3), and its hardening heat is 840-850 degree, and temperature is 180-190 degree; (5) adopt centreless grinding equipment to carry out super grinding to bearing pin in above-mentioned (4), the required precision after its super grinding reaches 2-4 micron; (6) centrifugal polishing machine equipment is adopted to carry out polishing to bearing pin in above-mentioned (5).
The present invention is compared with background technology, one is adopt GCr15 material to make bearing pin and adopt metallic cementation to carry out thermo-chemical treatment to GCr15 bearing pin, make chain hinge pin have heat-resisting, wear-resisting, anti-oxidant, the corrosion-resistant several times that obtain to improve, the service life of bearing pin is multiplied; Two is the shear strengths strengthening bearing pin; By the extruding elastic deformation of gear piece aperture, improve aperture fatigue strength, reduce the wearing and tearing in bearing pin and gear piece aperture, improve whole chain service life and static strength; Three is that bearing pin adopts GCr15 material surface metallic cementation intensive treatment, tensile strength is generally 6.0-7.0KN, can meet the demand of high speed variable load many impacts engine, the extruding elastic deformation of gear piece aperture completely, the friction pair formed with bearing pin improves fatigue strength, improves polishing machine.
