Abstract
The utility model relates to a special main shaft copper bush or a conical sand making machine, in order to fundamentally avoid a fracture phenomenon of the main shaft copper bush in case that tin and leak in a main shaft copper bush forming material spill if the main shaft copper bush in the conical sand making machine is overheated. An axial concave arc-shaped groove is formed on a semicircular surface of the axial inner wall of the main shaft copper bush and an oil inlet hole is formed on the wall of the axial concave arc-shaped groove. The main shaft copper bush has the advantages that firstly, the main shaft copper bush overcomes a critical defect that an oil film becomes invalid when a main shaft and the main shaft copper bush are constantly kept under a high temperature state because a contact surface of the main shaft, with the main shaft copper bush, is dynamically supported as an oil film surface and the main shaft, in a rotating process, is constantly kept in a gravity rolling process with a stressed surface (one half of inner wall of the main shaft copper bush) of the main shaft copper bush; secondly, because the main shaft copper bush is composed of copper, tin and lead, the tin (or tin and lead) of the main shaft copper bush is melted and spills over from the wall of the main shaft copper bush when the main shaft and the main shaft copper bush are under a high-temperature state, at which time the main shaft copper bush is represented as a honeycomb-shaped structure, causing a defect that the sand making machine fails to work.

Utility model content
Purpose of design: avoid the weak point in background technology, design a kind ofly from according to solving circular cone sand making machine in overheated the caused main shaft copper sheathing moulding material of main shaft copper sheathing, institute is stanniferous, lead overflows, the main shaft copper sheathing causing is the special-purpose main shaft copper sheathing of circular cone sand making machine of the axle sleeve fracture phenomena that honeycomb porous structure brings.
Design: in order to realize above-mentioned purpose of design.1, the axial inwall semi circular surface of main shaft copper sheathing has the design that arcs of recesses groove and arcs of recesses groove walls have fuel feed hole, is one of technical characterictic of the present utility model.The object of doing is like this: while being subject to the guiding of eccentric bushing to make eccentric rotary due to main shaft in circular cone sand making machine, all the time with the axial inwall of main shaft copper sheathing (copper sheathing) there is crowded pushing away in half to the face of its main shaft active force, and there is not crowded pushing away in second half axial inwall, to not there is not to squeeze main shaft copper sheathing internal face open arc connected in star and the fuel feed hole of pushing surface in the application for this reason with spindle face, this fuel feed hole injects lubricating cooling oil with pressure by the oil supply system that is positioned at sand machine processed outside the lubrication chamber consisting of main shaft and main shaft copper sheathing internal face groove, lubricating cooling oil in this cooling chamber is due in flow regime, not only can play the effect of cooling main shaft copper sheathing and main shaft, and can guarantee that the oil film between main shaft and main shaft copper sheathing can be because high temperature lost efficacy, guarantee the good lubrication state between main shaft and main shaft copper sheathing, the more important thing is and fundamentally solved in the main shaft copper sheathing material that the material that forms main shaft copper sheathing causes due to high temperature tin or tin and plumbous and overflow generation that formed main shaft copper sheathing is cellular situation, avoided the main shaft copper sheathing intensity that caused thus to lose to the greatest extent, the generation of phenomenon of rupture.2, the design of lubricating oil cool cycles oil supply system for sand machine processed, is two of technical characterictic of the present utility model.The object of doing is like this: because lubrication circulation oil supply system had both had fueller with pressure, there is again oil cooling system, it can either force the oily cold oil of cooled profit to inject in the lubricating oil cooling chamber of main shaft copper sheathing and main shaft axial plane formation, again can by cooling main shaft, main shaft copper sheathing and lubricated after be with gentle lubricating oil carry out cooling, recycle after filtering, thereby reach object cooling, lubricated, environmental protection.
Technical scheme: the special-purpose main shaft copper sheathing of a kind of circular cone sand making machine, the axial inwall semi circular surface of main shaft copper sheathing has axial arcs of recesses groove and axial arcs of recesses groove walls has fuel feed hole.
The utility model is compared with background technology, the one, solved because main shaft and main shaft copper sheathing touch face mutually and be oil film face dynamic support, and in gravity, roll process all the time with the stress surface (half of main shaft copper sheathing inwall) of main shaft copper sheathing in the process that main shaft gyration rotates, cause main shaft, main shaft copper sheathing all the time in the condition of high temperature, the critical defect that causes oil film to lose efficacy; The 2nd, solved because main shaft copper sheathing consists of copper, tin, lead, when main shaft, main shaft copper sheathing are during in the condition of high temperature, tin (or tin and lead) fusing that forms main shaft copper sheathing is overflowed from main shaft copper sheathing wall, cause main shaft copper sheathing to become alveolate texture, intensity is lost to the greatest extent, the fracture of main shaft copper sheathing, fragmentation, the defect that causes sand machine processed to work.
