After the study of the Party Committee of the Youth League Department, the head of the Youth League only approved 10,000 yuan for the brick factory. Dapeng came to Qi City Machinery Manufacturing Factory, only 450 brick machine is 8500 yuan, and the reducer of Hubin Machinery Factory is 5500 yuan, if you add brick machine, mixing, batching machine and other accessories, the total is at least 20,000 yuan, what should I do if this difference is 10,000 yuan?

Dapeng bought white drawings, pencils, erasers, rulers, garden rules, and sketchbooks from the store. Dapeng clearly knew that he had not learned mechanical drawing at all, and only with the vague experience he had 14 years ago, could he create his own fantasy machine? He went to his stepfather's house in the south bureau to plan the calculation of the size, modulus and speed ratio of the outer and inner jacket of the brick casing, cylinder head, spindle, reamer, bearing seat, mud board, mouth, gear, etc., and he wanted to draw and design a 450 large brick machine by himself.

Mapping should be proportional, in the family many children are still noisy, at night Dapeng took the tool white paper to the second floor of the waiting room of the railway station, lying on the marble floor began to calculate the proportional mapping. In order to save money, you can't draw a general assembly drawing, because you go to the factory to process and find that the brick making machine processing cost is high, and decentralized drawing will inevitably consume more energy, because it is a certain risk.

For example, the main cylinder is matched with a reamer by 450cm, and the outer and inner cylinder blocks of 1.2cm thick steel plates, plus the rifle wires welded in the cylinder, the material must be hard, and the outer body size must be 453cm. For the calculation of the diameter, number of teeth and modulus of the gear, the helix angle of the four sections and three sets of reamers, the reamer and the spindle keyway, the speed of the flap gear, the spindle thrust and the bearing of the spindle, the tip surface of the connection between the mud cylinder head and the dragon mouth, and the installation of the base of the machine body all affect the feasibility of the operation of the whole machine, and also affect the quality and output of the production of bricks. Dapeng has never engaged in mechanical drawing, and completely recalls the experience of maintaining machinery in the two years in the Fularji Brick and Tile Factory, and he also has to design a large machine suitable for the actual situation of the Corps, which is even more difficult.

In the middle of the night, more than a dozen people with red armbands, including police officers and plainclothes, came to clean up the waiting room without tickets. They saw the drawings all over the ground, some picked them up and looked at them suspiciously, and some called Dapeng aside and asked, at first they were as nervous as they were about spies. Dapeng explained the difficulties of mapping, and in the end, one of the police officers left sympathetically, and the red armbands followed.

Three days later, Dapeng came to the Weidong Factory, the original name of the factory was the Peace Machinery Factory, which was a military factory specializing in the manufacture of cannons and secrets. When Dapeng was in elementary school, his teacher specifically instructed the students that it was strictly forbidden to look at the arsenal when they were on the slide, because the school and the arsenal were only separated by a wall. Therefore, the current factory name is "127" Weidong Factory, which is a product of the Cultural Revolution Movement, because the rebels do not want peace, so it was changed to Weidong Factory.

Director Li brought Dapeng into the factory, and the engineer Yin of the first workshop reviewed the drawings, and the total cost of the work and materials was 1,500 yuan, but the gears were not included, because there was no high-frequency furnace in the factory, so it was recommended to go to the second machine tool factory for processing. Dapeng proposed to the factory that because it was a distribution map, it only required that all the gears be assembled into a complete machine by the workshop free of charge after they were transported, and the two sides reached an agreement because the Corps was far away to facilitate transportation.

If you go to the second machine tool factory to process gears, you will have to pay at least 1,000 yuan, the brick machine part is 2,050, plus the reducer is 5,000 yuan, the total amount is 8,000 yuan, and the accessories of the mixer and batching machine are at least 5,000 yuan.

In that harsh winter, Dapeng walked on the road, walking, walking and suddenly stopped, drawing calculation formulas on the snow with his fingers, fellow travelers were stunned by his abnormality, some of them had already walked a long way and still looked back? People seemed to wonder that he was probably a madman? On the trolleybus, Dapeng always gave up his seat to others, and he often kept talking while standing, sometimes unconsciously gesturing with his hands, and the passengers cast puzzled glances at him, and some even regarded him as mentally ill and deliberately avoided and peeped aside.

Due to the stomach problems of Dapeng who forgot to sleep and eat, he often had unbearable pain, and sometimes he put his appetite on the corner of the desk in the workshop, and the beads of sweat like soybeans rolled down his face. Director Li and the engineer asked him to go to the hospital, and he also had to explain the baseline of the gear on the drawing, if it was misaligned, the gear would be scrapped. He always felt that time was passing too quickly and was not enough? Why should people have problems eating and sleeping? Look at the dirty clothes, long hair, itchy lice on his body, and the sour smell all over his body, if he goes to the waiting room again, he may be caught as a blind stream. And whenever he couldn't help vomiting, he poured out the sour bitter water in his stomach and wiped away his tears, but he felt so comfortable and relaxed.

It doesn't matter as a full-time mechanic, because it is the first time for Dapeng to design, draw, and process the machinery by himself, and it is more difficult to be unique. According to the 750 rpm of the spindle of the 6160 unit and the diameter of the spindle pulley, to drive the three-stage reducer designed by itself, the speed of the spindle of the brick machine must be reduced to 60 revolutions per minute, especially the material and modulus of each gear must meet the standard, as long as there is a problem, the whole plant is paralyzed. In addition, there are various parts of the mixer and batching machine, as long as there is a mechanical error, the consequences will be unimaginable.

Dapeng returned to the Corps with the processing agreement of the two factories, and the secretary of the regiment headquarters was in charge of the brick factory, and he handled a check for 9,600 yuan and a bank of 400 yuan to bring with him, and asked Lou Fengchang, the chairman of the trade union, to go with him. Lou Fengchang was originally from the Public Security Bureau, originally a land-sitting household, and now he is going to return to the city with his lover, his lover Xiao Zhao is a rural educated youth in the rich district of Qi City, and it is said that 82 is the last batch to return to the city.

Gai Yingjie, a neighbor of Dapeng's house in the brick factory of the regiment headquarters, also made a transfer point to return to the city, and all battalions and companies of the regiment have blown the wind of returning to the city, even if the last batch of educated youths return to the city, Dapeng cannot return to the city before completing the mechanical update. And his lover Hua Ying is more than eight months pregnant, and before he and Chairman Lou left, he just asked to repair the cigarette pipe that was about to be emptied. He ignored the high fever of the two girls with tuberculosis in the lungs, and he and Chairman Lou came to the Qishi factory for the sake of machinery.

In the workshop of the second machine tool factory, Dapeng found that there was a problem with the large gear of the mixer, and the miller actually set the misalignment in the milling gear, processed it with the center line of the tooth, and the entire large gear was scrapped. The workshop director apologized and promised to deliver the work within 10 days. Chairman Lou wants to go to the rich district to do a transfer, of course, it is also the reason that his lover has returned to the city.

Chairman Lou returned to Qi City in April, and Dapeng transported all kinds of gears, purchased bearings, and V-belts from the Second Machine Tool Factory to the Weidong Factory, and all the assembly could be completed in a few days. Dapeng couldn't take Chairman Lou to his stepparents' house, that was because Wang Luming had caused conflicts in the family. At the hotel, Dapeng specially asked for mutton shabu, and three days later, the corps sent a car, and the address of the meeting was the gate of the Railway Central Hospital, which was also the place where his parents worked before their deaths. Dapeng also proposed to explain to the secretary of the brick factory that when the car came, he would bring ten bags of white noodles, one was to return to the city for private use, and the other was to give it to the factory in exchange for pipes for public use.

On the third day after Chairman Lou left, Dapeng waited in the railway hospital, he could no longer see the big photo of his mother's advanced worker, missed his mother, and recalled the places he had often visited since he was a child. He introduced that most of the classmates worked on the railway, and also mentioned that the captain Guo Ruiping had returned to the city to get married, and worked in the Jiefangmen Street Office, and her parents had been rehabilitated. I think that he was also the outstanding squadron leader in the class of the railway middle school at the beginning, but now only his own family has drifted away, pessimistic and distressed and afraid to meet his classmates, but the psychology of returning to the city makes him yearn for it even more.

The car of the Corps came, Dapeng took them to the stepfather's house in the South Bureau House, and unloaded ten bags of white noodles from the car. The city's food supply is only 8 catties of noodles per person per month, and the rest is mainly coarse grains, and Dapeng leaves two bags for his stepparents and four bags of noodles for relatives. Occasional meals at stepparents' houses over the past two months should also be compensated.

It is said that the Qiqihar Railway Bureau was revoked and changed to the Qiqihar Railway Branch, and there are regulations in the bureau that all those who have not taken over after a year of retirement will be dealt with according to the reduction, and it seems that the matter of Dapeng succession is really not easy to do.

Two days later, Master Li and Xiaoma came, loaded the four bags of noodles and drove into the Weidong factory, the factory gave a cannon barrel more than three meters long, and also picked some cannon barrels in the waste heap, the long one can be used as a mixer shaft, the short one can be welded with the inner sleeve of the main machine reamer, and the material used to make the cannon is particularly hard, which is difficult to process by the machine tool. When the crane loaded the machine onto the car, Director Li said: "Someone paid 8,000 yuan to buy this brick machine. ”

Dapeng asked Master Li to drive to the real estate section, and just got out of the car and met Secretary Duan Song Changli, he took Dapeng to the collective office, and asked Wei Qingfu to open a letter of business transfer, the purpose of which was to temporarily transfer Dapeng back to work in the collective, and then transfer to the state-owned enterprises in the future, because this was the last time the educated youth returned to the city, and he had to accept the decision of the leadership.

The two drivers had to run back that day, but they always had to eat, and they asked for a few dishes at the restaurant in the living section opposite the train station, and twelve cups of loose beer were served in a basin. The three of them were eating and drinking and their stepfather came to complain, so why didn't they go home for dinner? The two masters explained that they were going back that night, and exchanged a few polite words to each other, and the stepfather excused himself and left.

The stepfather's youngest son, Liu Dachuan, works in the locomotive depot, he is married, and the woman works in the railway and electricity depot, so they all go to live at the woman's mother's house, and the stepparents let Dapeng live in their new house. However, a year ago, his stepfather broke his intestine and had seven stitches, and he was plagued by severe urinary interception, and Liu Jiayi still looked for him a job in the cinema, trying to want the life of his old stepfather?

After all, the stepfather has more than ten years of nurturing, Dapeng introduces the past with love and hate, and the two drivers sympathetically comfort him. They are all educated youths in the countryside, and the last chance to return to the city, they also handled the transfer of educated youths to return to the city.

Dapeng and the driver suddenly had unbearable stomach pain after three rounds of drinking, and they want to ask what happened? Please see Chapter 75——: The embarrassment of the last group to return to the city.
