Chapter 226

After all, such things as drawings are only calculated. Without even doing strength experiments on materials, they basically rely on the empirical parameters that they wrote down for design. As for whether their drawings can be converted into real objects, Xia Lin was also very upset.

This is also the reason why he wants to organize a research team and carry out a research plan.

Dividing the 40 senior employees of the research team into ten groups of four, appointing all the dwarf masters as the group leaders, directly under their own leadership, Xia Lin immediately started to act.

According to the order of first easy and then difficult, the first is the problem of gravity crusher, which is composed of closed workbench, metal gravity hammer, clutch device and gear mechanism.

This is actually a simple forging machine, but such a clumsy piece of equipment consumes a lot of steel and is relatively easy to manufacture.

After the steel was in place, the finished product was quickly produced by the dwarf masters. The conclusion of the trial was that the work efficiency was very low, but it was still acceptable.

The first tackle was successful, and this result encouraged many team members.

Then there is the research on the manufacturing of the conveyor belt. It is necessary to lift hundreds of heavy materials ten meters high and put them into the feed port of the blast furnace without stopping every day. The requirements for all aspects of the conveyor belt are very high.

Naturally, the best material for making conveyor belts is rubber. Xia Lin found the bicycle research and development team led by Master Holkin in a corner of the machining factory, and found that Master Holkin was happily riding the pure bicycle they had drawn according to the drawings provided by Xia Lin. The hand-built bicycles were having fun in the open space outside the wide and flat factory building, and the dwarf masters who were on the sidelines looked at him with envy and eagerness as he rode round and round in the open space.

"Hey, Xia Lin, your bicycle is really good, but it's useless in the wild! In the wild, the horned goats raised by our tribe are better. No matter how rough the terrain is, those old guys can take it with you. Let's jump on it!"

Seeing Xia Lin and his party, Master Holkin rode his bicycle to them happily, straddled the ground with his thick short legs, patted his mount under his crotch with satisfaction and said to Xia Lin.

"Master Holguin, the main purpose of our bicycle is not to be used for wild riding, it only needs to be able to drive on the road.

If there is a need, we can also make certain changes to the design of the bicycle, such as adding some shock absorption equipment, widening the width of the tires, enhancing the rigidity and stability of the frame, so that it can drive in the mountains and forests.

But even that is impossible compared to the horned goat mounts of your dwarven tribes.

The bike you've got out now has wooden tires, and it's nowhere near a horned goat.Master Holguin, haven't those raw rubbers been made into molded tires according to the process I gave you? "

Xia Lin said and carefully looked at the bicycle under Master Holguin's crotch. The basic frame is made of hollow high-carbon steel pipes connected by bolts, the seat cushion is made of cowhide and natural sponge, the hub, spokes and chain, and the gear plate They were all handcrafted by dwarf masters. Except that the height of the seat was lowered a lot because it was a birthday present for Hurley, the shape looked the same as the old-fashioned bicycles produced by factories that Xia Lin had seen in her previous life.

Considering the technical level of the dwarf masters, the error of these fine parts may be smaller than the 0.1mm range that Xia Lin previously requested.

However, the tires, one of the most critical components, did not use the rubber tires that Xia Lin expected. They were still maple wheels made by the dwarf masters themselves.

"It's not that easy. We heat and chop the strange raw rubber according to the process you said, and then add carbon black, rosin, paraffin, kaolin, alkaline earth, etc., and then roll it with a rolling mill. But try Those tires obtained by rolling more than a dozen times are easy to break, and I am afraid they will not meet your requirements."

When it came to business, Master Holkin got off his bicycle, and led a group of people through the back door to the machining factory while pushing. At a corner of the back door, they had already set up several small ovens, and several The newly manufactured machinery and equipment were placed aside, where more dwarves and employees were carrying out various operations with a weird smell of glue.

"Look, these are the fetal slices we have produced during this time!"

Master Holguin handed over the bicycle in his hand to a dwarf, and then took out a box from under the table beside him. Inside, various small grids were separated by wooden boards, and a volume of scrolls was placed in the grid marked with serial numbers. black leather-like object.

Xia Lin touched these rubber tires one by one. The unvulcanized rubber was still a bit dry and hard at room temperature in early spring. He frowned and took out a few rubber tires. The piece was bent for a while and then broke. If it only has this quality, it is really not good for making tires.

"It may be that those compounding ingredients are added too much. You can consider reducing the amount of carbon black, kaolin and magnesium oxide a little bit. Forget it, let me adjust the amount of the formula for you!"

It's only a few days away from Hurley's birthday. Xia Lin is not going to take that wooden wheeled bicycle to commute. Those kind of wooden tires are fine for riding on flat roads. If you really want to go out and ride on the roads of the current imperial capital Okay, I'm afraid Hurley's buttocks with the cushioned shock absorber will also be broken into four petals.

Compared with the formula that Master Holkin tried, Xia Lin reduced the amount of compounding ingredients by more than half, and asked the workers to restart the furnace to produce rubber compound.

After adjusting the formula, the color of the rubber compound produced this time is obviously much lighter than before.After the cooling was completed, Xia Lin tried to stretch it a few times. The toughness and elasticity were good, but the surface was quite sticky, and a slight setback on the table would leave clear black marks. Obviously, this kind of The quality can't meet Xia Lin's needs.

"...follow this recipe and try again!"

Xia Lin pondered for a while, and took a compromise value between the rubber formula Master Holkin tried last and his own formula just now to continue the production of ingredients.

Finally, after trying for a day and a half, Xia Lin obtained a compound rubber formula with good strength, toughness and elasticity. After calendering, this compound rubber became a tire film with a thickness of two to three millimeters. .

A roving mesh is placed between the films as the skeleton of the tire, and the leather glue used by cobblers is applied layer by layer to bond and compact. The outermost film is printed with anti-skid lines by a printing machine, and finally the tire is obtained. Finished solid tires.

Put the tires into a simple vulcanization furnace and heat them with sulfur. After a period of vulcanization, Xia Lin finally saw the appearance of the world's first rubber tires, accompanied by large strips of film. That's for making conveyor belts.

"Is this the finished tire you want us to make? It doesn't look like much."

Master Holguin stepped forward curiously and squeezed a solid tire exuding a strong sulfur smell, curled his lips and said, for rubber, a strange thing that only an alchemist would be involved in, this dwarf master obviously has no understanding of metal and Smelt that strong interest.

"But with this tire, a bicycle is a bicycle!"

Xia Lin patted these vulcanized tires that were still emitting slight heat with emotion, looked at the bicycle beside him, and immediately asked people to install the two tires on the hub of the bicycle with great interest, adding these two presents After the gray and black tires, the bicycle finally fit the image of the bicycle in Xia Lin's memory.

Although the whole body of this bicycle is basically handcrafted by a group of senior craftsmen, strictly speaking it is a luxury handicraft product, not the industrial product Xia Lin expected, but it is enough to make him happy.

Riding this bicycle with great interest in the open space at the back door of the machining factory for a few laps, Xia Lin experienced the feeling of riding a bicycle again, and nodded in satisfaction.

The shock absorption effect of solid tires is naturally not as good as the hollow pneumatic tires of the previous life, but it is quite comfortable to ride on such a relatively flat ground. This level is enough to give Hurley a birthday present. When the time comes The roads in the imperial capital are almost repaired, and Hurley can occasionally go to school by bicycle, experiencing Xia Lin's student life in her previous life.

After telling Master Holkin to use the remaining raw rubber raw materials to continue to try to make better quality rubber mixes, Xia Lin took the rubber belts produced in the same batch back to the stronghold of the research team to continue the research on the manufacture of conveyor belts.

According to his own design, Xia Lin used a rubber belt as the conveyor belt, and glued leather strips on the front and back to enhance the friction. The wrought iron rods that were also glued to the leather strips were used as rollers, and a screw-type tensioning device was used to ensure that the conveyor belt was not loose. These parts are then assembled with hydraulic power rollers and brackets to obtain a formed conveyor belt.
