Abstract
The invention relates to a re-manufacturing machining process of the surface of an inner hole of a hydraulic cylinder scrap guide sleeve. The process comprises the following steps that the hydraulic cylinder guide sleeve is cleaned in the machining early period; size repair is carried out on the hydraulic cylinder guide sleeve, and shot blasting is carried on the inner surface and the outer surface of the hydraulic cylinder guide sleeve; the inner surface and the outer surface of the hydraulic cylinder guide sleeve are cleaned and purified through acetone; self-fluxing nature powder is sprayed on an outer thread, the outer surface, the wall surface of the inner hole and grooves of the hydraulic cylinder guide sleeve; the inner diameter and the outer diameter of the hydraulic cylinder guide sleeve are remelt through medium-frequency induction heating equipment, aging treatment is carried out after the inner diameter and the outer diameter of the hydraulic cylinder guide sleeve are remelt; size machining is carried out on the hydraulic cylinder guide sleeve; QPQ processing is carried out on the surface of the hydraulic cylinder guide sleeve. The re-manufacturing machining process of the surface of the inner hole of the hydraulic cylinder scrap guide sleeve has the advantages that the scrap hydraulic cylinder guide sleeve is re-machined to the original size and original structure, the thread can be machined in the original position, the anti-corrosion performance and anti-tension performance of the hydraulic cylinder guide sleeve are improved, the service life of a hydraulic cylinder is prolonged, and cost is lowered.
Description
technical field [0001] The invention relates to a remanufacturing process for the inner hole surface of a scrapped guide sleeve of a hydraulic cylinder, in particular to a remanufacturing process for the inner hole surface of a scrapped hydraulic cylinder guide sleeve. Background technique [0002] Traditional hydraulic cylinder guide sleeves are generally treated as scrapped directly after they are scrapped. At present, there are also some processes for remanufacturing hydraulic cylinder guide sleeves. However, the current common process of reprocessing the inner hole of the hydraulic cylinder guide sleeve is difficult to achieve the original size, structure, anti-corrosion performance and anti-stretch performance of the hydraulic cylinder guide sleeve. If the size and performance cannot meet the requirements, the guide sleeve of the hydraulic cylinder has to be scrapped, which increases the production cost and causes waste of resources. Contents of the invention [0003...
