Abstract
A lined and flanged bush and method of manufacturing the same comprising: providing a liner having an aperture; locating the aperture in the liner around the spigot such that the liner lies on the surface; and stamping out the blank around the spigot to provide a lined and flanged bush.
Claims16
A method of manufacturing a bush from a blank comprising:
- providing a blank having a surface to be lined and at least one spigot upstanding from the surface;
- providing a liner having an aperture;
- locating the aperture in the liner around the spigot such that the liner lies on the surface;
- adhesively bonding the liner to the surface;
- and stamping out the blank around the spigot to provide a lined and flanged bush, the bush comprising a flange providing a flange surface formed from the surface of the blank, the flange surface surrounding the spigot, the bush comprising an adhesive bond between the flange surface and the liner and a mechanical bond between an outer edge of the liner and an edge of the flange as a result of the stamping step.

A flanged bush comprising:
- a spigot having a flange which provides a flange surface surrounding the spigot;
- and a liner having an aperture through which the spigot is located, wherein there is an adhesive bond between the flange surface and the liner and a mechanical bond between an outer edge of the liner and an edge of the flange;
- wherein the mechanical bond is provided by a stamping process which cuts firstly through the liner and then the material of what will comprise the flange to provide an element of compression of the liner at the very edge of the flange surface and create the mechanical bond between the liner and the flange.
A flanged bush being formed by a method comprising:
- providing a blank having a surface to be lined and at least one spigot upstanding from the surface;
- providing a liner having an aperture;
- locating the aperture in the liner around the spigot such that the liner lies on the surface;
- adhesively bonding the liner to the surface;
- and
- stamping out the blank around the spigot to provide a lined bush having a flange with a mechanical bond formed between an outer edge of the liner and an edge of the flange and an adhesive bond between the liner and a surface of the flange.
