摘要:
A sheet metal drawing equipment capable of rapidly and positively carrying out sheet metal drawing without skill and effectively smoothing a surface of a sheet metal material. The equipment includes a first operation mechanism provided with at a distal end thereof with a bit weldable to a surface of a sheet metal material to be drawn, a second operation mechanism manually operated to pull up the first operation mechanism, and a leg structure for supporting the second operation mechanism. The second operation mechanism includes a support section for rotatably supporting the first operation mechanism.
