Definitions
- the present invention relates to a manufacturing method of a flanged type linear bushing, which includes machining an edge of an outer sleeve at a predetermined angle for a smooth coupling between a flange and the outer sleeve, coupling the flange and outer sleeve, welding the coupled portion with high energy beam or welding the coupled portion with high energy beam of good linearity while feeding filler metal to a welding site, and a flanged type linear bushing manufactured by the above method.
- a flanged type linear bushing is manufactured by a cold forging method, a brazing bonding method, a adhesive bonding method, a shrink fitting method, a method for screwing an outer sleeve and a flange, a wedge and nut assembling method, and a snap ring fixing method.
- the cold forging method has several problems since a manufacturing process is complicated. If uniform and stable structure is not obtained by relieving of stress generated during the cold forging and annealing of fibrous structure, the cold forging process causes difficulty on materials to having a good turning performance, surface evenness, and mechanical properties due to the stress resulted from carburization for hardness.
- Copper brazing is one of the most used method in metal bonding, but has a problem in that it causes lowering of strength of the parent metal, lowering of surface hardness and increasing brittleness since material is deformed and decarburized during brazing due to required high temperature for the melt flow of copper. Furthermore, the adhesive bonding method has several problems since it is very difficult to control appropriate surface roughness, tolerance of dimension, maintenance of clean surface and environmental pollution from bonding material. The method for screwing the outer sleeve and the flange has a problem in that process costs are expensive since the process must be precise, and the screw joint may be loosened during use.
- a manufacturing method of a flanged type linear bushing which includes the steps of: machining an edge of an outer sleeve at a predetermined angle for a smooth coupling between a flange and the outer sleeve; forming a recess on the outer periphery of the outer sleeve in uniform depth and width in consideration of thickness of the outer sleeve for an easy laser welding after coupling the flange and the outer sleeve with each other; machining an inside edge of a flange along with inner circle of a flange in a form corresponding to the recess formed on the outer sleeve to permit the easy laser welding; coupling the flange and the outer sleeve manufactured by the above steps; and welding the outer sleeve with recess and the flange with inside edge cut which are coupled with each other, with high energy beam, or welding the coupled portion with high energy beam of good linearity

- the present invention can improve productivity through automation and reduce manufacturing costs since the outer sleeve and the flange are separately designed and manufactured and integrally coupled with each other and the coupled portion is easily welded with high energy beam of good linearity, for example, laser.
- the present invention can save management expenses by reducing stock quantities of components in comparison with the integrated type linear bushing made by the brazing bonding method and the cold forging method since the outer sleeve and the flange are separately manufactured and can be supplied when they are needed to be coupled and welded with high energy beam of good linearity.
- the present invention can minimize deformation of a welded portion and obtain good welding performance since high energy is supplied only to the tiny area of welded site in a short time of period using high energy beam. It is necessary to design and manufacture a flange and an outer sleeve in a structure to have no influence on the outward appearance and operation of using before they are welded with high energy beam of good linearity.
- the present invention can further prevent or minimize defects generated by thermal stress of welding when the outer sleeve and the flange are coupled and welded with each other with high energy beam of good linearity, since a stress buffering structure capable of absorbing stress generated by welding is formed adjacent to a welding position at the flange.
- the present invention can strengthen the welded portion and provide good welding performance by absorbing stress generated during direct welding of outer sleeve and flange, of which materials have different compositions, respectively.
- the filler metal made of alloy (nickel, chrome, and others) and having a predetermined diameter is located and fed on the coupled site between the flange and the outer sleeve if necessary so that the filler metal is co-melted with the materials of coupled portion by high energy beam and penetrated into the coupled portion.

- a flanged type linear bushing is manufactured by mechanically coupling an outer sleeve and a flange without forming a special structure for permitting an easy welding in order to simplify a manufacturing process, and welding the coupled portion with high energy beam.

So, to solve the above problem, additional heat treatment (800°C to 900°C) has to be done before grinding and cleaning the material after bonding of the outer sleeve and the flange.

- the recess of the outer sleeve and the machined structure of the flange may have various forms according to the use purpose of the flange and a position coupled with the outer sleeve. That is, the recess of the outer sleeve and the structure of the flange are not restricted to one form, and may form various structures (15) and sizes (round type, inclined type, tiered type, valley type, and so on)in consideration of easy and good welding, outward appearance after welding, relief of stress, and so on.
