Abstract
The present invention relates to the oil cylinder renovation technique, is a kind of production technology that adopts restoring oil cylinder by diameter-reducing method.Production technology of the present invention is: select-undergauge-correction-turning-heavy boring-dash change-floating boring-honing-turning-groove milling-plating-check.Adopt production technology restoring oil cylinder of the present invention, have the following advantages: the oil cylinder quality of reparation is good, and rehabilitation cost is low, the repair rate height, and restoring oil cylinder in enormous quantities, the oil cylinder of reparation is than the oil cylinder long service life with other method reparation.
Description
The present invention relates to the oil cylinder renovation technique, a kind of production technology that adopts restoring oil cylinder by diameter-reducing method of saying so accurately.
The coal mining supporting is supported by chock, develop into metal and should wipe pillar, now under the requirement of coal department to the hydraulic prop transition.But the main part oil cylinder in addition on the hydraulic prop, it is consumable accessory, increase along with the hydraulic prop usage quantity, the oil cylinder of scrapping is more and more, this has caused very big obstacle for popularizing of hydraulic prop, causes certain economic loss to the colliery, how to make twice laid, saves hot rolled seamless steel tube material in short supply, alleviating the situation of oil cylinder supply shortage, is one of problem of solving of machining industry.The oil cylinder renovation technique that adopts has several at present: the soldering filling process, and poor, the rough surface of its repairing quality easily comes off; Iron plating at lower temperature technology, the rehabilitation cost height, repair rate is low, complex procedures rapid wear sealing ring; Enlarge endoporus, change other the part technology of being correlated with of processing, owing to change other part, management trouble, the difficult popularization; Endoporus coating oil resistant wear-resistant plastic production technology, endoporus low precision rehabilitation cost height easily comes off; Endoporus enlarges, edge stainless steel sleeve production technology, and the good rehabilitation cost of repairing quality is high, and repair rate is low.
The objective of the invention is, it is good to provide a kind of production technology of dwindling oil cylinder aperture, restoring oil cylinder to make its technology reach the oil cylinder quality of reparation, the repair rate height, and rehabilitation cost is low, is fit in enormous quantities the reparation.
Restoring oil cylinder production technology of the present invention is: select-undergauge-correction-turning-heavy boring-dash change-floating boring-honing-turning-groove milling-plating-check.That is: the oil cylinder that will scrap is earlier selected according to the oil cylinder repairing condition, adopt the special equipment undergauge then, proofread and correct handgrip body end ellipse garden degree and bus linearity, car goes base end, process corner again, the heavy boring endoporus, oil cylinder that can not heavy boring changes over to and dashes the preface of exchanging work, and dashes the oil cylinder with behind the heavy boring that meets dimensional requirement after becoming and together changes floating boring over to, honing after the floating boring, car process area and base end again, mill out with identical steel wire trough on the new oil cylinder, tinning bronze on oil cylinder, check at last.
Accompanying drawing 1 is a process chart of the present invention.
The combined process flow chart, the narration embodiment of the invention:
It is transparent to select oil cylinder flawless and casing wall in the oil cylinder of scrapping, oil cylinder outer diameter D 〉=4113.5mm, and wall original error≤0.70mm, interior pitting point is lighter, and coating comes off serious, and the amount of contracting is between 0.5～0.8mm, and interior pitting point is serious, needs undergauge extremely
