Abstract
The invention discloses a piston rod machining method. The piston rod machining method includes the following steps that a section of materials are cut and shaped preliminarily; a large hole is machined in the outer side of the tail end through turning; the necked portion in the middle is machined at the same time; the large hole formed through turning is reamed through a reamer; a small hole is drilled in the head end and is bored through a borer, and the bored small hole is subjected to shrinkage processing; then, a piston rod is subjected to heat treatment and is subjected to quenching under the temperature ranging from 123DEG C to 432DEG C for one to two hours three times, and the surface of the piston rod is subjected to carburizing treatment; then, internal stress relieving is carried out, and the finished piston rod is obtained. The piston rod machining method simplifies production steps, original trivial processing steps are merged or deleted, and the quality and service life of the piston rod can be effectively guaranteed.
Description
Technical field
The invention belongs to mechanical manufacturing field, particularly a kind of processing method of piston rod.
Background technology
Piston rod plays an important role in cylinder operation, only have piston rod partly to reach quality requirements, oil cylinder, plunger and spring could be assembled smoothly, guarantee the normal operation of engine, the product of producing at present exists matter crisp conventionally, the problem of poor toughness, can affect life-span and the normal operation of engine.
Summary of the invention
The processing method that the object of this invention is to provide a kind of piston rod, the piston rod good toughness of this method processing, quality is good, and the life-span is long, can guarantee the normal operation of engine.
The technical scheme adopting is:
A processing method for piston rod, comprises the following steps:
Intercept one section of material, carry out preliminary shaping.
Sidecar macropore outside tail end, processes middle necking section meanwhile.
Institute's car macropore, is used reamer to carry out articulation.
At head end, bore aperture, the aperture having bored is used boring cutter bore hole, after boring is good, carries out shrinkage cavity processing.
Then piston rod is heat-treated, quenching 123-432 degree Celsius, time 1-2 hour, in triplicate, then effects on surface carries out Carburization Treatment.
Then eliminate internal stress and process, obtain finished product.
Its advantage is:
The present invention has simplified production stage, and original loaded down with trivial details processing step is merged and deleted, can effectively guarantee its quality and life-span.
The specific embodiment
A kind of processing method of piston rod
Intercept one section of material, carry out preliminary shaping.
Sidecar macropore outside tail end, processes middle necking section meanwhile.
Institute's car macropore, is used reamer to carry out articulation.
At head end, bore aperture, the aperture having bored is used boring cutter bore hole, after boring is good, carries out shrinkage cavity processing.
Then piston rod is heat-treated, quenching 123-432 degree Celsius, time 1-2 hour, in triplicate, then effects on surface carries out Carburization Treatment.
Then eliminate internal stress and process, obtain finished product.
