Abstract
The invention discloses a bearing bush cleaning method. The method comprises bearing bush cleaning comprising scale removal, rust removal and oil stain removal. The scale removal process comprises removing scales through an emery cloth or a steel wire brush. The rust removal process comprises washing a bearing bush through a dilute sulphuric acid or dilute hydrochloric acid solution with the content of 10-15% for 5-10min, washing the bearing bush through hot water at a temperature of 80-100 DEG C for 5-10min, washing the bearing bush through cold water for 30-60min and drying the bearing bush at a temperature of 50-60 DEG C. The oil stain removal process comprises washing the bearing bush through a sodium hydroxide solution at a temperature of 80-90 DEG C for 8-15min, washing the bearing bush through hot water at a temperature of 80-100 DEG C for 25-30min, taking out the bearing bush and drying the bearing bush at a temperature of 60-80 DEG C. The method has simple processes, realizes thorough cleaning, easily guarantees quality, improves production efficiency and reduces a production cost.
Description
Technical field
The invention belongs to a kind of bearing shell cleaning technology method.
Background technology
Bearing metal must cast in and could normally use on bearing shell matrix.Owing to bush material used is different, also different from the viscous of bearing and ability, viscous and ability power is to be lowered successively by bronze, mild steel, cast steel, cast iron.For viscous and that ability is poor material, dovetail groove can be gone out in bearing shell Surface Machining or bore a little blind hole to increase bond strength.Whether the bearing shell surface of pour a bearing alloy is cleaned, and its strong influence the bond quality of it and alloy.Therefore bearing shell must be cleaned out. and existing bearing shell cleaning technology method, the qualification rate of the product clear up thoroughly, caused the later stage to produce is low, and production efficiency is low, and production cost is higher.
Summary of the invention
It is an object of the invention to for Shortcomings part in above-mentioned technology, the present invention provides a kind of bearing shell cleaning technology method, improves the quality of production, increases qualification rate, reduces production cost.
The technical scheme realizing the object of the invention is as follows:
A kind of bearing shell cleaning technology method, its process step is: bearing shell cleaning includes oxide skin, rust cleaning, cleaning oil pollution；Described oxide skin is cleared up, and adopts emery cloth or wire brush to remove except method；Described rust cleaning, washes 5-10 minute with 10-15% dilute sulfuric acid or dilute hydrochloric acid solution, is then placed in 80-100 DEG C of hot water and rinses 5-10min, then uses cold water flush 30-60min, and dries under 50-60 DEG C of condition；Described cleaning oil pollution, with 80 DEG C--90 DEG C of soda lyes rinse 8-15min, then with 80 DEG C--100 DEG C of hot water injection 25-30min, take out and dry under 60-80 DEG C of condition.
The present invention provides a kind of bearing shell cleaning technology method, and this process is easy, cleaning is thorough, is easily guaranteed that again quality, improves production efficiency, reduces production cost.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described:
A kind of bearing shell cleaning technology method, its process step is: bearing shell cleaning includes oxide skin, rust cleaning, cleaning oil pollution；Described oxide skin is cleared up, and adopts emery cloth or wire brush to remove except method；Described rust cleaning, washes 5-10 minute with 10-15% dilute sulfuric acid or dilute hydrochloric acid solution, is then placed in 80-100 DEG C of hot water and rinses 5-10min, then uses cold water flush 30-60min, and dries under 50-60 DEG C of condition；Described cleaning oil pollution, with 80 DEG C--90 DEG C of soda lyes rinse 8-15min, then with 80 DEG C--100 DEG C of hot water injection 25-30min, take out and dry under 60-80 DEG C of condition.
The present invention provides a kind of bearing shell cleaning technology method, and this process is easy, cleaning is thorough, is easily guaranteed that again quality, improves production efficiency, reduces production cost.
The preferred embodiment of the present invention described in detail above.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to the design of the present invention without creative work.All technical staff in the art, all should in the protection domain being defined in the patent claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
