Countercurrent 1982

Chapter 77 Doubt
Looking at the materials just borrowed from the library, Cheng Qingyan quickly entered the state of being settled.

As a newcomer who has just entered the technology department, Cheng Qingyan still has her own ambitions for work and technology.

Nowadays, there is a common occurrence in the departments of organs and departments where people are too busy and eat a big pot of rice, but this does not affect Cheng Qingyan, who is new to the factory.

As early as when she was in secondary school, she often brought some technical books to her father for advice and exchanges. The father and daughter would also talk about the equipment and technology in the Red Star Gear Factory, so Cheng Qingyan had just joined the factory. It has been less than a year, but he is already familiar with the various technical equipment of the factory.

It's just that in the past two years, my father seems to have given little attention to high technology. Cheng Changlin is now more interested in social entertainment and fighting for money in the factory. The father and daughter have less discussion about technology. Now, I can't talk a few words for almost a month.

In Cheng Qingyan's view, the agricultural gears currently produced by Hongxing Gear Factory are a very backward product. There has not been much improvement in craftsmanship for more than ten years, and the machining accuracy is low, only about grade [-] to [-]. Compared with foreign imports There is still a big gap in the machining accuracy of gears above grade [-].

In addition to the gear machining accuracy, the surface hardness of the gears produced by the Hongxing Gear Factory is also backward.

Nowadays, the hardness processing of gears by Hongxing Gear Factory mainly relies on traditional heat treatment, and the parameters of this heat treatment process are still the same as those of SL when SL was established. However, there are still many problems in the wear resistance, fatigue resistance and corrosion resistance of the workpiece.

And now Cheng Qingyan's recent focus on the powerful shot peening technology was what she had seen from the relevant materials found in the school library when she was in secondary school.

The so-called powerful shot peening is a surface strengthening process, that is, a cold working process in which the surface of the workpiece is bombarded with pellets and the residual compressive stress is implanted to improve the fatigue strength of the workpiece.It is widely used to improve the mechanical strength of parts as well as wear resistance, fatigue resistance and corrosion resistance.

The advantages of shot peening are that the equipment is simple, the cost is low, it is not limited by the shape and position of the workpiece, and the operation is convenient.

Although there are also powerful shot peening equipment imported from abroad for this kind of gear, in this year when foreign exchange is precious, this kind of equipment is given priority to the military industry, which is naturally unavailable to the 'step-mother' unit of the Red Star Gear Factory. .

Cheng Qingyan is trying to design a simple shot peening equipment by learning from foreign materials, which can improve the product quality of the gear factory to a certain extent, and at least prolong the service life of the gear.

"Xiaoyan, let's eat." Just as Cheng Qingyan was comparing the materials and writing and drawing in her notebook, her mother's voice came from the kitchen.

"Uh." Cheng Qingyan replied, then she looked away from the book, got up and walked to the kitchen to help her mother serve meals.

Braised eggplant, stewed octopus, homemade tofu, seeing the steaming sumptuous dinner on the table, Cheng Qingyan suddenly felt her index fingers open, and picked up her chopsticks to cook the eggplant.

"Wash your hands!" The mother rolled her eyes at her from the side.

Cheng Qingyan stuck out her tongue, turned and walked towards the kitchen.

"Old Cheng, hurry up and eat." Yang Xiufang took a bowl of rice from the steamer on the ground, put it on the table and said, "What's the matter with you today? You look so annoyed, who are you angry with? "

"It's okay!" Cheng Changlin put out the cigarette in the ashtray, got up and sat at the dining table.

"My dad must have had a disagreement with the factory leaders because of work." At this time, Cheng Qingyan sat down at the dinner table after washing her hands, and said with a small mouth, "Mom, it's not like you don't know, my dad is so stubborn. , what he has determined, others can't pull back ten cows."

"Hmph..." Cheng Changlin snorted angrily, and then said: "If I really quarreled with the factory secretary, I would have recognized him, but I let a young worker who just joined the factory for a month to criticize him. Now, in front of the leaders and cadres of the whole factory..."

"What!?"

As soon as Cheng Changlin's words fell, Cheng Qingyan's mother and daughter were stunned.

"Dad, it's impossible, right? Which worker is so daring to criticize you?" After a while, Cheng Qingyan said with a look of surprise.

"Old Chang, what's going on?" Yang Xiufang also frowned and asked.

"It's like this..." Cheng Changlin sighed, put aside the matter of the factory meeting this morning, and added a sentence at the end: "I really didn't expect that Zhao Dongsheng would have such a hand. An apprentice was used as a cannonball, and he beat me and the factory manager Qin all over the place..."

"Old Zhao has been the secretary for decades. No one in the factory knows that he is the best at gaining power. Qin Gang has been a factory director a few times before, but who can be a secretary? People are not in a stable position. , I already said that you don't want to provoke him, but you don't listen, you said that you are a technical person who wants to participate in the meeting with the director and secretary, so can you have good fruit to eat?" Yang Xiufang shook her head and said.

"What do you know? If I didn't have Qin Gang, would I be able to be the chief engineer now? Isn't that chief propaganda chief of yours also decided by the director of the factory? You have to have a conscience!" Cheng Changlin paused, then said: " Moreover, Zhao Dongsheng has always been on the wrong side of me. He has long wanted to replace me with someone who is more obedient. In recent years, almost all of the technical school students who have been newly assigned to the technical department have been turned into party activists by him. A person's heart is indispensable... Anyway, this Zhao Dongsheng is a hidden danger, if I don't weaken him, I will be overtaken by him sooner or later!"

When he said these words, Cheng Changlin was a little excited. He couldn't say such things in the unit, so he could only go home to vent.

"Don't worry, Dad, I will always support you daughter!" Cheng Qingyan showed a cute smile, and asked again after a while, "By the way, Dad, is the Duan Yun you mentioned also a technician?"

"It's just a little apprentice in a workshop, that silly boy who committed suicide a while ago!" Cheng Changlin said.

"It's him!?" Cheng Qingyan suddenly looked surprised when she heard the words.

"I don't know where this kid copied the lathe technical transformation plan, and he has become a popular person in the eyes of the secretary. This kid Tian Feng is also an idiot, and he was even tricked by Duan Yun. The factory manager and I are quite passive, and I'm about to lose my old face!" Cheng Changlin said angrily.

"It turns out that, I understand..." Cheng Qingyan said suddenly.

"Understand what?" Cheng Changlin turned to his daughter and asked.

"I saw that Duan Yun the night before yesterday, and he also went to our factory night school to study. I heard that he only had a junior high school degree. I was surprised at the time. Logically speaking, our factory workers have to graduate from a technical school at least for the night supper registration threshold. It seems that the secretary should have arranged for him." Cheng Qingyan said.

"Damn joke! A junior high school student also wants to take the Yedao exam. He doesn't know how much he weighs. He really thinks that if he has a secretary, he will be able to go to college and improve his career!" Cheng Changlin's face flashed a touch of disdain. In his bones, he has the kind of arrogance and arrogance of an intellectual, and has never paid attention to ordinary low-educated workers. After a while, he said to Cheng Qingyan with a serious face:
"Xiaoyan, stay away from this kind of stupid boy in the future!"

"Yeah." Cheng Qingyan responded casually, but a hint of doubt flashed through her clear pupils...
