Number of Copper Sleeve Models
In the middle of April 1971, when I just started work in the morning, the section chief, Master Yang, called me to his workbench. He looked me up and down and smiled at me."Little Stone, I have a job for you.”As he spoke, he took out a blueprint from his work desk and handed it to me. "This artifact is very simple. I think you should be able to complete it independently.”I opened the blueprint and placed it on Master Yang's workbench. I carefully browsed through the blueprint.
The name of the work piece on this drawing was " Copper Sleeve ". It was a non-standard mechanical part. The length of this mechanical part was 300mm, the diameter of the inner hole was 160mm, and the wall thickness was 10mm. The number of pieces required was 3. It seemed that this job was not complicated. It was very simple and easy to do. Therefore, I answered Master Yang confidently,"I promise to complete the mission."
I took the blueprints of the mechanical parts that I had just received back to my workbench. I calmed down and first analyzed the blueprints. He carefully read the list at the bottom right corner of the blueprint. He also considered the related links other than the blueprint.
First, according to the list at the bottom right corner of the drawing, the number of casting required was confirmed to be three. Indeed, the copper bushing mud core was made by the scraper process.
The second was to determine the moisture content and the amount of water loss of the casting according to the material requirements of the part. The specific external size of the casting were determined.
Thirdly, according to the length of the clay core, the diameter and length of the clay core box were determined according to conventional requirements.
Fourthly, according to the bottom right corner of the drawing, he determined the casting processing process requirements, leaving aside the amount of cutting for mechanical processing, and thus determining the mechanical processing allowance required for the casting wood mold production process.
According to the list at the lower right corner of the drawing, on the basis of meeting the basic requirements of the pilot, prepare to start the production process of the casting wood mold according to the specific size requirements of the blueprint and the specific requirements of the above four points.
After confirming the foundation of the production process. I found a large plate in the model room and placed it on my workbench. After sharpening my planer knife again, I took the hand-pushed carpenter's planer and shaved off all the old drawings left behind in this drawing class. A long pile of pale yellow wood shavings was left under my workbench.
On a large wooden drawing board, according to the specific size on the blueprint, combined with the four requirements mentioned above, a steel ruler, a square ruler, an eraser, a compass, and other drawing tools were shown on the workbench. I used an HH pencil to place the sample, and then used a red pencil to mark the processing allowance on the drawing board. After these preparations are done, I will ask the section chief, Master Yang, to help me review the results of my lofting in the drawing class. Master Yang wore his presbyopic glasses and carefully looked at the design I placed. He nodded in satisfaction. She smiled and said,"Sure." It was alright. He continued to do it. After you're done, bring it to me for examination.”
After receiving Master Yang's initial recognition, he became bolder. He held a steel tape measure, a carpenter's pencil, and a carpenter's saw. I went to the wood yard in the model room to cut the materials. First, he found a section of wood with a diameter of about 180mm and a length of 400mm. Then, he found two small pieces of wood with a thickness of 30mm. Then, he got on the woodworking machine in the model room and turned it into a copper casting model with a mud core. Then, he used these two small pieces of wood with a thickness of 30mm to make a scraper-type mud core box. The process of making the model was very simple. It was nothing more than using carpentry tools to cut wood. Saw a saw. He used a round shovel to nail two semi-circular wooden blocks onto a long wooden board. He was making a scraper. Then, he polished the surface of the wooden model to remove all the traces left by the pencil and sanded it. It could be done with a little more effort...
After the wooden model was completed. After a self-examination. Then, we will hand it over to our class leader for inspection. After confirming that it is qualified, we will hand it over to the section leader, Master Yang, for re-examination. After the section chief confirmed that it was qualified, I finally wrote down my name, the name of the casting, the material requirements, the number of pieces needed, the user name, and the time to complete the model on the surface of the model. On the deadline for completion, I clearly wrote 1971, 4, 13. Master Yang, the chief of the workshop, stamped the model with the word "qualified". Then, the technician in the workshop took it to the sand casting section and handed it to the next process. He took it to the sand casting team in the workshop to arrange the sand casting of the batch of casting.
After a few days, I had completely forgotten about it. Unexpectedly, this matter actually developed in another direction. Moreover, the final result of the development was unexpected, making me not know whether to laugh or cry.
Half a month later, the technician in the workshop suddenly came to the model room. She went straight to me and asked me to verify a question: I checked my work diary and solemnly told him that the number of copper sets required for processing was three. Not only did I tell him the name of the user, the material, and other information about this batch of copper sleeves. At the same time, he also told her clearly," Because the user requested three pieces, I made a scraper model for the clay core box. The two semicircles combined to form a cylindrical clay core box.”
The technician promised as she quickly left me. She rushed to the factory technical department for further verification. After the production technology department approved it, the result was still three pieces. She never came looking for me again. A few days later, I met the technician at the door of the workshop. She quietly told me,"This is bad. The apprentice in the sand casting section. Wang Dongsheng, who entered the factory with you. He got the number wrong and didn't even ask us to verify it. He actually thought that 3 pieces were 413 pieces. The biggest problem was that he had already made more than 200 pieces. Fortunately, this user didn't cause any trouble. At that time, due to the temporary change in the production tasks of the users, the demand for copper sleeves of that size had greatly increased. This problem was finally solved. However, in the future, can you write the number of parts in a bigger font and the time of completion of the model in a smaller font? Don't write them all in the same size, okay?”
I quickly apologized." I'm sorry. I'll pay more attention in the future. I'll definitely change and do as you ask. This kind of thing will never happen again.”
One afternoon, I met the apprentice of the sand casting section. This Wang Dongsheng came with us from Hua Yang Training Class. At that time, he was in Class Seven. In Class Seven, he's the third oldest in terms of age. We all call him Third Brother. This third brother's reaction time was relatively slow, but he was very strong. Usually, when he jokes with us, he hits us quite hard. We all avoided him a little. She didn't want to confront him head-on.
At this moment, this third brother didn't stand on ceremony with me at all. He ran straight to me across the road and rushed up to me first. He grabbed my chest collar and shouted loudly at me,"You rock, you've really screwed me over. 413 items, you only need to make 1 set of scraper core box. You're really too lazy and too deceptive. He's just trying to kill me."
I wasn't willing to either. I fiercely broke free from this third brother's hand and bluntly retorted,"I am considering the model according to the requirements of the 3 pieces. I'm sure you didn't see it clearly. I wonder what you're looking at work? Even if what you said is right, even if there are 413 pieces, I definitely can't just make one clay core box. At the very least, I have to make a few sets of models. If necessary, the factory will also consider making metal models. Even if what you said was right and you insisted that you were right, why didn't you go to the workshop office and report it to the relevant leaders? Or come to the model room to find me to make a clay core box.”
The apprentice called Third Brother was so angry that he didn't say a word for a long time.
That's right. He did not report it himself. Instead, he lowered his head and took it for granted. He squatted on the wet floor of the sand casting section with his head down and used it as a three-piece model to make more than 200 sets of copper casting. I have to say that he did create a pioneering work in the sand forging section.
I made a face at him, stifled my laughter, and said seriously,"I should congratulate you. You made more than 200 bronze casting using the model of three bronze casting." He had indeed created the highest record for the sand casting section.”
The third brother immediately jumped up." You make it sound so easy. You stone wrote all the Arabic numbers the same size. You're making me feel wronged." You made me comfortable."
I quickly apologized to him,"I'm sorry, I'll treat you to Twice Cooked Pork tonight." How about two portions? Can I shut your mouth? But then again, you didn't manage to get 1971413 pieces. Even if you have good eyesight, it's already pretty good. You old man. When working, one had to have an extra head and a pair of eyes to see clearly. Remember, if you encounter such a situation in the future, you must report it to me immediately. Without my orders, you are not allowed to move. Do you understand?"
The third brother laughed as he rolled up his sleeves and swung his fists at my head very quickly, wanting to hit me."I'm going to hit you, the chief.”
Got it. I quickly lowered my head and dodged the attack of the pair of fists. I turned around and ran back. And he would run as far as he could. You have to run, I have to run. That person is taller than me and stronger than me. Whether it is in terms of size or strength, I am not his opponent. I really can't win against him. "Moreover, this so-called apprentice, no matter what, he came out of Huayang Town's new worker training class and was assigned to Third Company together with us. Everyone was living in the same room, and the relationship between the two brothers was quite good. We all know that his brain isn't enough. He usually has some problems with his thinking and his reaction is a little slow. I can't compete with him. To be honest, she couldn't get anything out of him. I'm also afraid that this will damage the relationship between us.
It was true that in that era, the management of enterprises was chaotic. There were very few capable management personnel. Many of the professional technical and management personnel in the factory had been transferred to the May 7th Cadre School to view the world of reform through labor. Our old company commander was indeed an amateur in managing a business. She was not very educated, and she did not finish her high school. He was loyal to the revolutionary cause and worked hard. In the past, when he commanded troops to fight in the war to resist the United States and aid Korea, he was able to set a good example and was indeed a good person. However, managing the production and operation of the company was indeed very taxing. The old company commander also noticed that the apprentice had made a large number of copper jackets. However, he could not make up his mind based on his feelings. That was why he didn't interfere with the apprentice in time. There was only one technician in the workshop. She was too busy. When the technician in the workshop realized it. It was already too late.
I turned around and fled back to the model room. Master Yang called out to me and said,"The workshop is about to assign a new batch of students. I'll go to the workshop office to pick them up now. If there's anything you need, just look for me.”Then, he hurriedly walked out of the model section.
