Abstract
A method of manufacturing bearing seal for use in a roller bearing is provided. A steel coil of a preselected width is fed into a ring rolling machine to form a closed coil ring. The closed coil ring is then welded along the butted joint. The welded closed coil ring is then fed to a series of pre-forming machines wherein the desired profiles of the final bearing seal are formed.
Claims11
A method of manufacturing a bearing seal comprising the steps of:
- feeding a steel coil of a preselected width into a ring rolling machine,
- cutting a divided length of the steel coil and
- rolling the length of steel coil into a closed coil ring having a butted joint,
- the butted joint of the closed coil ring is welded to form a welded steel coil ring,
- transferring the welded steel coil ring to a weld bead removal station, then
- transferring to a weld flattening machine
- wherein any weld bead at the butted joint between the two cut ends of the steel coil ring is flattened to form a flattened steel coil ring,
- transferring the flattened steel coil ring to a first pre-forming machine wherein a first profile is formed in the flattened steel coil ring to form a first profiled steel coil ring,
- transferring the first profiled steel coil ring to a second pre-forming machine wherein a second profile is formed in the first profiled steel coil ring to form a second profiled steel coil ring, transferring the second profiled steel coil ring to a third pre-forming machine wherein a third profile is formed in the second profiled steel coil ring to form a third profiled steel coil ring,
- and transferring the third profiled steel coil ring to a final forming machine wherein a final profile is formed in the third profiled steel coil ring to form a final profiled steel coil bearing seal, further comprising a step wherein the second profiled steel coil ring is transferred to a third pre-forming machine wherein a third profile is formed on the second profiled steel coil ring to form a third profiled steel coil ring prior to forming the first profile.
