Embodiment Construction

[0018] specific implementation

[0019] According to attached image 3 The overall mechanism diagram of the press, and the attached Figure 4 , 5 , 6, and 7 show the specific size diagram, we carry out specific design, simulation, finite element analysis, strength check, motion simulation, deformation analysis, the above specific design meets the maximum tensile deformation and bending deformation under the pressure of 50,000 tons They are all within 0.5mm, and the maximum bearing strength is within 200Mpa. According to the above analysis, we decided that all parts of this equipment are made of 45# cast steel, and the processing is realized by 12M gantry CNC milling machine. After the manufacture, the 50,000-ton die forging press is assembled together to realize the manufacture of this 50,000-ton die forging press. The total weight of this die forging press is about 2,200 tons, the largest single piece has a total weight of about 170 tons, and the working stroke of the pres...

Abstract

Provided is a method for designing and manufacturing a stand column laminated type 50-thround-ton die forging press. The method is characterized in that stand columns are combined in a laminated mode and tensioned to form a whole; an upper beam, a lower beam and a sliding block are integrated; multiple oil cylinders are used for driving and multiple hinges are used for force amplification; each stand column is provided with an upper seam allowance and a lower seam allowance. By means of function combination and detailed design, the largest press in the world currently is designed ultimately and is easy to manufacture.

Description

technical field [0001] The invention relates to the design and manufacture of major equipment. Background technique [0002] Large-tonnage die forging presses have just started in China. Generally, presses of more than 10,000 tons in the forging industry are basically imported. The price of imported presses is 10,000 yuan / ton, and the price of 10,000 tons of presses is 100 million yuan. Recently, a 35,000-ton press was produced in China, with a research and development cost of over 1 billion yuan. Xi'an also recently produced a 40,000-ton press, with a manufacturing cost of 784 million yuan. R & D, manufacturing and import costs are too high, which seriously restricts the processing and manufacturing of major parts in our country, which in turn affects the country's manufacturing capacity. Contents of the invention [0003] Under the above circumstances, we have designed a 50,000-ton press, which is the most powerful press in the world today, as attached image 3 shown. ...
