Abstract

925,956. Making bumper bars. JOSEPH SANKEY & SONS Ltd. July 3, 1961 [Sept. 27, 1960], No. 33086/60. Drawings to Specification. Class 83 (2). A method of making a bumper bar for a motor vehicle comprises forming an aluminium alloy sheet clad with pure aluminium into a bumper bar, subjecting said bar to artificial ageing consisting of precipitation heat treatment to cause the required strength to be imparted to the bar and thereafter bright anodizing the aluminium cladding. In an example, a bumper bar is pressed from a fully annealed clad aluminium sheet, trimmed and pierced, attached to a jig to prevent distortion and solution heat treated at 520‹ C. for 20 minutes and precipitation heat treated at 195‹ C. for 2 to 3 hours. The bar is finally mechanically polished, chemically brightened and anodized to a maximum depth of 0.007 mm. and the anodic film sealed by steam or hot water. A resin-type lubricant may be used during pressing. The bar may be formed by rolling. The preferred thickness of the cladding when applied to one side of a sheet only is 7.5 to 10% of the total thickness of the material. Hub discs and overriders may also be made by the method.
