Brake shoe assembly formed using hot staking method

A method of forming a brake shoe assembly said method comprising:

• precision stamping a substantially net shaped web blank having a semi-circular outer peripheral edge provided with a plurality of tabs projecting radially outward therefrom;
• precision stamping a table member having a plurality of apertures formed therein corresponding in spacing to the tabs on the web blank;
• bending the table member to form a semi-cylindrical segment;
• assembling the web and table causing the web tabs and table apertures to interlock, locating the parts temporarily together;
• and
• joining a plurality of the corresponding tabs and apertures together using a hot staking process wherein the resulting joints do not extend substantially beyond an outer semi-cylindrical surface of the table, said hot staking process comprising the steps of moving a hot ram into contact with a free end of said tab thereby heating said tab, allowing said tab to achieve a desired hot forming temperature and then extending said ram toward said table member thereby causing said free end of said tab to deform outward thereby interlocking said tab and said table member.
