Problems solved by technology

Due to the complexity of the surface morphology of the elastic foil bearing, the machining precision requirements are also high, and its preparation method has always been a very difficult problem.
Using molds to process corrugated foils is one of the more popular methods at present, but usually a set of molds can only process one kind of corrugated foils, which cannot meet the processing requirements of large quantities of multi-form corrugated foils
If multiple sets of molds are used and the cost is high, it is not conducive to processing production and reducing costs

Abstract

The invention relates to a combined mold for processing gas thrust bearing bump foil of an elastic foil sheet, which comprises a bump foil processing mold ring 1, a bump foil processing mold ring 2, a bump foil processing mold ring 3, a bump foil processing mold ring 4, a bump foil processing mold ring 5, a bump foil processing mold ring 6 and a bump foil processing mold ring 7 which are nested and combined, wherein the bump foil processing mold rings (1-7) are connected together through a positioning cylinder 9, and bolts 8 are arranged at two ends of the positioning cylinder 9. A new combined mold structure can be formed by rotating one of the mold rings. The invention has the characteristics of compact structure, combined processing, low cost and high precision.

Description

technical field [0001] The invention belongs to the technical field of moulds, in particular to a combined mold used for processing wave foils of elastic foil gas thrust bearings. Background technique [0002] Elastic foil bearings have good self-adaptability and can operate under high temperature, high speed and high pollution conditions for a long time without auxiliary devices such as oil supply or control systems, so the structure is simple. Due to the complexity of the surface morphology of the elastic foil bearing, the processing accuracy of the elastic foil bearing is also high, and its preparation method has always been a very difficult problem. Using molds to process corrugated foils is one of the more popular methods at present, but usually a set of molds can only process one kind of corrugated foils, which cannot meet the processing requirements of large quantities of multi-form corrugated foils. If multiple sets of molds are used, the cost is high, which is not ...
