Breakthrough in constant trial and error and challenge

Forging domestic large aircraft C919 steel iron bone

In fact, as my country's independent research and development, the ton-level giant press has created a world record, the forging operation of the 80000-ton die forging press has no successful experience to learn from, and it all depends on exploration and practice. In order to continuously improve the subsequent molding and surface quality of products, Ye Linwei and others are still exploring and making breakthroughs.

Just a month ago, an old acquaintance of the operation team came to the front of the 80000-ton die forging press. He was seen with a stopwatch in his hand, concentrating on timing the operations team that was forging the aircraft die forgings. He is Luo Hengjun, the head of the C919 large passenger aircraft aviation die forging research and development team. Under his leadership, the team realized the localization of key components of the C919 main landing gear for the first time. And his appearance often means that the research and development team will have to give strength to Ye Linwei's operation team.

He asked Ye Linwei's operation team to control the transfer time of die forgings within 60 seconds. "Every second you save this temperature to reduce the loss of two degrees. This is a great improvement to the subsequent molding and surface quality of our products." Luo Hengjun said.

"Reduce by half on the basis of the current process time." Faced with this challenge, Ye Linwei's team was slightly embarrassed. But soon took up the challenge and began to make preparations intensively, which was bound to gnaw down this hard bone.

The installation, clamping and placing of materials on the mold challenge the scene. In the countdown of Luo Hengjun, the operation team carried out a series of processes nervously and quickly. However, because it was the first challenge, the operation team was in a hurry in a tense atmosphere, and the final completion time exceeded the expected time by 20 seconds.

The first failure was a big blow to Ye Linwei and the team members. However, after learning from the experience of failure, they quickly adjusted their state and started the second challenge. They were more methodical this time than the first time.

"5. 4. 3. 2. One" As Luo Hengjun pressed the chronograph, Ye Linwei and the others succeeded in the challenge of "59 seconds!

"Looking for experience from the problem, forging technology has matured." Ye Linwei said. In the process of trial and error and challenge, Ye Linwei and his team members constantly improved their skills and forged the steel and iron bones of the domestic large aircraft C919.

When Luo Hengjun recalled the scene of the first flight of C919 at Shanghai Pudong Airport in 2017, he lamented, "In an instant I felt that my eyes were a little bit moist. It's full of steel and iron bones, which our team has built for it with heart." When Ye Linwei saw the C919 soaring in the air, he said: "More and more people will feel a power made in China."

Because of love, so struggle. Because of the struggle, so forward. Because young people who are constantly running enthusiastically connect their love and struggle with the "heavy weapon of the country", Chinese-made talents such as domestic large aircraft and 80000-ton die forging presses can "start at the end of the line and stand in the sky".
