Promote the authors bend small leather efficiency

Bend small leather advance authors 2021 - increase 02 - 24 ( Zhang mine group) Since this year, a coal companies adhere to rely on scientific and technological innovation dig potential authors, independent innovation grinder spindle seal belt set set of repair process, repair the cylindrical grinding machine spindle seal belt untight seal caused by the wear and tear, oil and other problems, can be cut down the cost of replacement grinder spindle more than sixty thousand yuan a year. The company in production and processing of hydraulic cylinder, cylinder parts live column, the piston rod mill sequence in the process, the equipment in the high strength work for a long time, the surface abrasion of the grinder spindle seal belt, appear the untight seal, comprehensive problems of oil leakage, can appear sometimes tile burning phenomenon of holding shaft, seriously affected the factory's production efficiency and product quality, create quality is not stable, delay the construction period etc, need to buy replacement spindle to solve a problem, because the old equipment manufacturers have no this type of accessories, need special customized, and expensive, supply for more than 20 days, seriously affected the production schedule. Factory leadership and maintenance personnel after repeated argument that through the study of the improvement of main shaft sealing tape processing, cylindrical grinding machine oil leakage problem can be solved. Scheme is determined, they will disassemble grinder spindle, with other devices on the main shaft seal belt grinding surface, using waste bearing endothelial embedded in the main shaft seal belt ( Due to the bearing endothelial HRC61 - hardness 64 fully capable of full shaft seal with hardness requirements) Reprocessing of waste spindle after repackaging, successfully repaired shaft seal oil leakage problem, through the spindle precision measurement, concentricity reached 0 0. 002 silk, ovality reached 0 0. 001 silk, effectively solve the problem of low machining accuracy of the equipment, in the process of production and processing products can satisfy completely the requirements of the drawings. The bend small leather successfully solves the problems of equipment, repair equipment after the yield of 99. The goal of 9%, and higher than expected, about ten thousand multivariate, save money for the company to ensure the factory grinding sequence production run smoothly, meet the requirements of the production progress, accumulated experience for the future of the equipment maintenance, authors efficiency is realized.
