Production
System |
Heating
unit and Hotformer team up to form a complete, fully automatic production
system integrating all operations from bar to finished forging. There
are no billets or semi-finished parts piling up around the shop. There
aren't any supplementary operations either: piercing is done on the
machine, and there is no need for trimming. |

Bar
Storage Rack |
The
operation starts at the bar storage rack of the heating unit. Hot-rolled
bars are picked off automatically, then travel through the induction
coils on conveyor rollers for heating to forging temperature. One
bar after another, end-to-end. |

High
Operating Speed |
The
Hotmatic's high operating speed has a favorable effect on the forming
conditions. Thanks to the short cycle time, the metal hardly loses
any heat and stays fully forgeable right to the end. Furthermore,
the extremely short contact time of the tools with the hot metal keeps
tool heat-up to a minimum.
Result: longer tool life. It's a fact that the tool cost per forging
on the typical Hotmatic job is usually less than half that for conventional
forgings. |

Feed
Rolls |
The
Hotmatic feed rolls grip the hot bars and pull them into the machine.
A blank is cut off at the shearing station and moved to the dies,
where it is squared up and then pre-formed, finish-formed and pierced.
The finished parts drop onto a conveyor belt in the foundation that
carries them either to the intermediate storage bin or directly to
heat treatment or machining. Waste slugs and bar ends drop out separately. |
