Abstract

The invention discloses a steam turbine blade blank forging machine, and relates to the technical field of forging machines. The problems that a steam turbine blade blank forging machine cannot cleanan oxide skin and cannot clamp and fix a steam turbine blade blank are solved. The steam turbine blade blank forging machine comprises a forging device, wherein a hydraulic device is arranged on the inner side of the forging device, and the hydraulic device comprises a hydraulic rod and a stamping head, wherein the stamping head is arranged at the lower end of the hydraulic rod; the lower end of the inner side of the forging device is provided with connecting shells, wherein the two sides of the upper end faces of the connecting shells are provided with slots; and the two sides of the upper end of the stamping head are provided with first racks, one sides of the first racks are provided with first gears, one ends of the first gears are provided with first bevel gears, the lower ends of thefirst bevel gears are provided with second bevel gears, and the lower ends of the second bevel gears are provided with rotating shafts. According to the machine, the oxide skin can be automatically cleaned, and the steam turbine blade blank can be clamped and fixed.

Description

technical field [0001] The invention relates to the technical field of forging machines, in particular to a steam turbine blade blank forging machine. Background technique [0002] With the rapid development of social economy, steam turbine blade is the key part of steam turbine, and it is also one of the most delicate and important parts. It withstands high temperature, high pressure, huge centrifugal force, steam force, steam under extremely harsh conditions Combined effect of exciting force, corrosion and vibration, and water droplet erosion in wet steam zone. Its aerodynamic performance, machining geometry, surface roughness, installation clearance, operating conditions, scaling and other factors all affect the efficiency and output of the steam turbine; its structural design, vibration intensity and operation mode play an important role in the safety and reliability of the unit. The decisive influence requires the use of a forging machine during processing. A forging m...
