Everyone seemed to understand, and left the roller workshop and went to the inner ring production workshop.
What the workers here bring in are rough-processed semi-finished products and place them at the front of each production line. Everyone can clearly see the machines behind them. They are all lathes powered by human pedals. After several turns, inspections, and finally two grinding processes. After further inspection, it is put into the box.
The outer ring workshop is similar to the inner ring workshop and the processes are similar.
Compared with the roller workshop, these two workshops can generally be seen clearly. Although I don’t know why I do this, everyone can clearly see what I am doing.
Seeing that everyone had no problems, Lin Zeng led everyone into the cage workshop without saying much.
It starts with a brass strip, fed into a machine. When they arrived at the position, the operator on the side suddenly pulled the long pole beside him, and there was a "pop" sound, and a giant hammer fell from the machine. The copper tape was cut and many holes were punched.
Everyone walked to the machine and were too frightened by the earth-shattering sound to speak. I just saw that the operator was taking his time and feeding the copper strip into the machine. When there are more copper pieces cut off, someone will come and move them away.
Lin Zeng saw that everyone was not leaving, so he quietly asked the team leaders to give notice and walked to the next work station.
It's much simpler here. The copper strip with cut holes is rolled into a cylinder here, inspected and packed. The machine for rolling copper strips is also operated by two people. A person is pedaling on the shelf as motivation. One person feeds material into the machine.
A copper sheet was fed in, and after a few operations on the roller, it was rolled into a cylinder with holes. It looked very interesting, and everyone stopped here for a while.
Coming out of the workshop, Lin Zeng gathered everyone. Said: "You should be wondering why these workshops are built next to the river. This workshop, the machine that cuts the copper strips, is driven by water. The principle is not complicated, it is similar to the common water mill. Only there is no grinding here. stuff, but bring machines.”
Gongcheng's blog said: "If there is no water power and everything is done by people, I don't know whether it will be successful or not?"
Lin Zeng said: "Some are good, and some are not. Sometimes manpower is poor, and there is no way around it. However, manpower can still be used to cut off the copper belt here. But people can do it slowly, and there is no way to do it. The machine is good. Most of what you see next are processes that require the use of hydraulic power, so everyone should watch carefully."
After saying that, he explained a few more words and led the people into the workshop behind.
Behind these workshops is the river, with machinery arranged above it. It's just that I'm far away and can't see clearly what the machine looks like.
These rivers are water diverted from the rivers after dams were built upstream and canals were opened. Regardless of the height difference or water flow, hydraulic machinery is installed just right. The machine is not set directly on the river, as that would be too unstable.
As soon as I entered the workshop, I heard a huge "bang, bang, bang" sound. When everyone looked at it, they saw that similar to where the cage was made before, there was a huge machine cutting the iron bars into sections. The cut steel bars were taken to the nearby machinery. Then it is put into a mold and pressed by the machine to form the desired roller shape. These rollers are installed and become the blanks for the roller workshop at the back.
The homework here is simple and clear. Everyone looks at each machine one by one until the end.
Arriving at another workshop, it was almost the same as before. But here is a steel pipe, cut off section by section. Then burn it red before putting it into the mold. The machine pressed down with a "bang" sound, and it was a blank.
When we came out of the workshop, the sun was already setting in the west.
When everyone gathered together, Lin Zeng said: "There is nothing to say in these workshops behind, everyone can see clearly. Although these processes are simple, it is difficult to rely solely on manpower without water power. This is why the workshops are built in Next to the river. Without water power, many things are difficult to do. Okay, we have finished visiting the workshop, now we go to the place where the finished products are displayed to see what the finished products look like."
After that, he led everyone to the front of the factory, to a house with bright and clean windows.
This house is different from other places. There is a cabinet in the most conspicuous place in the middle, covered with glass. In the cabinet, there are finished bearings.
Everyone stepped forward and after looking at it, they couldn't help but suddenly realized: "So this is it!"
There is only one kind of bearing produced now, and they are all roller bearings. Just different sizes, there are more than a dozen models.
Lin Zeng introduced on the side. Said: "The bearings here can be used on various machines. The largest model can be used on vehicles, machines, etc. The smallest model is mostly used on textile machinery. Each of these models has its own size. It will not change. We print it into a book and supply it to other factories. When they design machines, they can directly choose the bearing model without thinking too much about the bearings."
After walking around, Mu Ying asked: "What kind of bearings are used in the cars I often ride in?"
Lin Zeng pointed to the middle three and said: "Generally speaking, the middle three are chosen according to the different cars."
Mu Ying came forward, looked at it for a while and said: "In this small circle, whether the car is equipped with it or not is completely different. Without bearings, the shaft is often broken, and there is not much cargo transported. With bearings installed, It can hold a lot of things and will last for many years.”
Lin Zeng said: "Our factory has not been built for a long time, and the bearings sold are rarely damaged."
Zheng Gangzhong asked: "I wonder how much these bearings cost? Considering the scale of this factory, they shouldn't be cheap."
Lin Zeng said: "The cheapest ones are the three types of bearings used in the middle car. Because they are easy to make and sell in large quantities. The small one costs about 500 Wen. The middle one costs 800 Wen. Wen, the biggest one is Guanqian.”
Zheng Gang wondered: "Why is the one in the middle the cheapest? Look at the smaller ones, don't they use less iron?"
Lin Zengdao: "The cost of raw materials is only part of the cost of the bearing, as well as labor costs and many other costs. Whether it is large or small, it is much more difficult to manufacture, and of course more expensive."
"Is there still something like this?" Zheng Gangzhong was very surprised and went to the display cabinet to take a look.
Public Transport Blog asked: "I wonder how many bearings your factory sells in a year?"
Lin Zeng said: "There are few sold now. One pair is two. The three most commonly used bearings can sell more than 20,000 pairs a year. The other bearings sell seven to eight thousand pairs."
Everyone couldn't help but take a breath after hearing this. A rough calculation shows that the factory can sell 50,000 to 60,000 yuan a year. According to Lin Zeng, this is still sold in small quantities.
Of course they sold less. According to estimates when the site was built, if the market expands, sales will increase tenfold. The simplest thing is that vehicles are the most commonly used means of transportation in this era. Almost every household needs a wheelbarrow. Every five or six households should have a big car. How many do these add up to?
