Extractor

A tapping machine belongs to the field of mechanical manufacturing. The tapping machine is composed of walking beam, crane, trolley and lifting mechanism. The transverse and longitudinal driving systems of the invention adopt mechanical transmission and frequency conversion control, and the starting and braking are reliable; The lifting mechanism adopts U-shaped groove as the guide rail, and the portal frame adopts high temperature resistant and self-lubricating wheels, which is durable without any additional lubrication system; The slab can be directly lifted out of the heating furnace and placed on the roller table stably to avoid the scratch and bruise of the slab, the collision of the roller table, the replacement and maintenance times of the roller table, and the service life is improved.
