Chapter 664: Hydraulic forging machine starts work!

When the concrete underneath is almost done, move the turbine base up and continue pouring concrete until the foundation is filled.

"Tea is here! Tea is here!"

The little scholar ran over with a big bucket of tea and was sweating profusely. He just happened to catch up with everyone after finishing their work.

"Gudong Gudong." After a few gulps of tea, the teenagers wiped their sweat and looked at the foundation and turbine base filled with dark gray cement, laughing.

Four days later, the cement in the foundation was completely dry, and the turbine base built in concrete He didn't move at all.

Su Chen shouted:"Start work!""

The erection of the main body of the turbine has begun!

Several idle brothers and Grandpa Su Kaisheng came to help.

Since the size of the turbine base and water wheel, and the distance between the base and the stream, Su Chen strictly calculated and controlled the erection of the turbine. It went very smoothly.

Two main and auxiliary shafts, one up and one down, were designed on the base. Two concentric bushings were installed on the front and rear of the main shaft to fix it.

A few brothers supported the water wheel and connected it to the main shaft with pins. They just finished it. Let go of your hand holding the water wheel, and the water wheel will slowly spin under the influence of the stream.

"The friction sound of"squeak, squeak, squeak" was heard. The gear of the main shaft was installed, and the gear on the other end of the main shaft on the base also began to rotate. The radius of the water wheel is much larger than that of the gear, so the force on the gear side is very large. , no matter how hard Su Chen pulled the gear, he couldn't stop the water wheel on the opposite side.

This force was very good.

A small bamboo crank slider mechanism was mounted underneath, and one end of the crank was connected to the gear on the countershaft of the base, and The gear on the main shaft is designed to move forward and backward.

A bamboo tube is installed at the end of the slider to simulate a hammer. The moving main shaft gear meshes with the countershaft gear, and the countershaft gear drives the crank to start rotating.

The crank in turn drives the slide rod to do With the reciprocating motion up and down, the bamboo tube at the lower end of the sliding rod starts to forge.

Move the main shaft gear away and no longer mesh with the countershaft gear, and the bamboo tube stops moving up and down.

This is the simplest and easiest way. Su Chen came up with the practical forging machine structure after going through the mechanical design textbooks in his mind.

An elder brother placed a bamboo basket horizontally under the bamboo tube to feel the strength, but he didn't expect that the bamboo tube would deform the bamboo basket in an instant. Fortunately, the bamboo basket had good elasticity and was not crushed.

Grandpa Su Kaisheng put his hand on the bamboo tube to feel it, nodded and said:

"Quite strong! Xiao Yi, it seems that the hydraulic forging machine you mentioned is not just for fun!"

"Grandpa Fourth, this is just a model. I am thinking that in the future we will build a large hydraulic machine downstream and use stronger materials. The gears can no longer be made of bamboo and must be replaced with stronger and more wear-resistant materials. This bamboo tube will have to be replaced by an iron pier when the time comes. It will be more exciting than Uncle Tie and his friends!"

"By then, the steel produced per day will no longer be just a few kilograms. As long as there is enough iron, it will not be tiring to produce hundreds of kilograms a day!"

"Ha ha! You are so ambitious! Grandpa Su

Kaisheng pointed at Su Chen and laughed,"Tell me, your fourth grandfather, what is the purpose of making this hydraulic forging machine that can produce hundreds of kilograms of steel a day?"

Su Chen said without hesitation:"In order to be able to make guns and cannons in the future!""
