Fully automatic pressing production line for large steam turbine blades

Abstract

The invention relates to a full-automatic pressing production line for a large turbine blade. The full-automatic pressing production line for the large turbine blade is characterized by comprising a gas heating furnace, a plurality of operation manipulators, a blade pre-profiling hydraulic machine, a blade shaping and trimming hydraulic machine, a workpiece flash waste material collecting device and a finished product storage device, wherein the gas heating furnace is positioned on one side of the pre-profiling hydraulic machine; the first operation manipulator is arranged on the other side of the gas heating furnace; the second operation manipulator is arranged on the other side of the pre-profiling hydraulic machine; the blade shaping and trimming hydraulic machine is arranged on the other side of the second operation manipulator; the flash waste material collecting device and the third manipulator are respectively arranged on the side which is close to the blade shaping and trimming hydraulic machine; and the finished product storage device is arranged on the other side of the blade shaping and trimming hydraulic machine. The full-automatic pressing production line has the advantages that workers do not need to operate in high-temperature and severe environments, the labor intensity is reduced, die changing operation is safe and reliable, flash waste materials can be quickly separated from one another conveniently, materials are discharged automatically, the movable worktable can be positioned accurately, and the product quality and the production efficiency can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of hydraulic machinery, in particular to a fully automatic pressing production line for large steam turbine blades. Background technique [0002] Steam turbine is the main prime mover of modern thermal power plants and nuclear power plants. It can also be used as propulsion power for large ships and warships, as well as various large working machines driven by metallurgy, chemical industry and other industries. The blade is an important component of the steam turbine. The traditional processing method of the steam turbine blade is mostly cast and then reprocessed by a press. Due to many factors such as the failure of the machining performance to meet the requirements and the backward production process, the finished product is prone to blisters. Its comprehensive strength cannot meet the design requirements of light weight and high strength of modern steam turbine blades. [0003] At present, the mold struc...

AI Technical Summary

Problems solved by technology

However, most of the flash generated by trimming will be bonded to the punch on the press, making it difficult to separate

At present, the separation of molded parts and flash edges is mainly carried out manually. However, since the molded parts and flash edges after die forging are both hot parts, that is, the operating environment temperature is as high as 1150 ° C, resulting in harsh working conditions for operators and high labor intensity. And seriously affect the production efficiency

In addition, because the feeding device of the traditional die forging press is located under the slider, and the temperature of the workpiece is too high, it is easy to cause hidden dangers such as frequent oil leakage and heat loss in the feeding system

[0006] When the blade is die-forged, because the flash is on the outside of the formed part, the manipulator cannot accurately remove the flash, and it is easy to take out the formed part together with the flash. The removal of the flash and the formed part affects the work the beat

If manual separation is used, due to the high ambient temperature around the press and the high labor intensity, workers cannot work for a long time, which seriously affects production efficiency

[0007] To sum up, traditional casting or forging equipment can no longer meet the needs of high production efficiency and lower operating costs, so a large-scale steam turbine blade automatic pressing production line is needed to meet the production and manufacturing process of large-scale steam turbine blades
