Technical field
The present invention relates to the processing method of automobile engine hinge wheel.
Background technology
The traditional processing method of automobile engine hinge wheel is to adopt powder metallurgy (metal or non-metal powder to be mixed rear compressing, and at the temperature lower than melting point metal, carry out sintering, utilize atom between powder to spread to make the process of its combination), the product of processing in this way, although injection molding technology is limited by what hardly aspect the complex appearance of formation of parts, but because the binding agent quantity of adding is more, can be because gravity effect deforms workpiece in heating process, therefore often need the extra more complicated and more expensive together special degreasing process that increases, make injection molding technology higher than conventional PM technique cost,
Summary of the invention
Technical problem to be solved by this invention is the deficiency existing for prior art, a kind of requirement that can meet product size precision and positional precision is provided, make again the processing technology of part reach state the simplest and that optimize, and the processing method of the automobile engine hinge wheel cutting down finished cost.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
The processing method of automobile engine hinge wheel, is characterized in that: it comprises the following steps:
Utilize uncoiling straightener to carry out uncoiling and alignment to sheet stock, then adopt smart impact machine to carry out essence punching to sheet stock, form and be circumferentially laid with a plurality of taper holes, center and be provided with the part that an axis hole, profile are profile of tooth;
Check that piece surface has or not rigid scuffing, then sub-elect without scratching product, clean, guarantee the noresidue globule, non-corroding and essence punching oil;
Pack part into double-ended grinding machine and carry out surface corase grind;
Chamfer machining is carried out on two sides to part tooth portion;
The burr that part chamfer machining is produced carries out deburring;
Part is carried out to high-frequency quenching heat treatment, wherein: 40 ℃ of the water temperature < of the use of quenching WATER AS FLOW MEDIUM, the tempering in latter 2 hours of quenching, the hardness requirement of part is reached: tooth surface hardness 600~750HV10, the effective case depth value that extreme hardness values is 480HV1 is 0.5~1.5mm;
Part is carried out to ball blast processing, improve surface smoothness;
Piece surface is carried out to one side fine grinding: first grinding part burr face, the rear grinding part edged surface that collapses;
Part is inserted to double-ended grinding machine again and carry out surface fine grinding;
The axis hole of Central of the parts setting is carried out to the processing of milling counterbore;
Again part is carried out to deburring;
Adopt demagnetizer to carry out demagnetization to part;
Part is cleaned to packing warehouse-in.
Press such scheme, the part thickness Assurance of Size that described double-ended grinding machine carries out after the corase grind of surface is
Press such scheme, the tooth portion chamfer dimesion after described part processing is R8.5 ± 0.5mm.
Press such scheme, the part thickness after described one side fine grinding is of a size of
Press such scheme, the part thickness that described double-ended grinding machine carries out after the fine grinding of surface again to part is of a size of
Press such scheme, the counterbore after described milling counterbore processing is of a size of diameter phi 45mm, dark 2.2 ± 0.1mm.
Adopt method of the present invention to have the following advantages:
1, to rush rear intermediate shaft hole following process surplus little for essence, reduces subsequent machining cost.
2, adopt the follow-up fine grinding surplus of two-sided mill corase grind part little.
3, after two-sided mill corase grind, adopt one side mill fine grinding, part both sides stock removal is more stable, also reduces the surplus of follow-up fine grinding simultaneously, guarantees the flatness of part.
4. milling counterbore after refining, part flatness is more stable.
