"Clang!"

"Bang!"

"ah!"

In the steam locomotive workshop under the Laoniu Transportation Team, a steam locomotive was still steaming, but it was already lying on the ground.

A craftsman who was helping to carry out the test was accidentally hit on the thigh by a broken bolt on the wheel, and blood flowed out.

"Hurry, send it to the Affiliated Medical Center of Guanshishan Academy for treatment!"

After a period of panic, the steam locomotive experimental site returned to tranquility.

"Shopkeeper Lao, our new steam locomotive has greatly improved the performance of all aspects. After using special rubber tires, the shock absorption performance has also been greatly improved.

However, the bolts connecting the wheels and the hubs always break after running for a period of time. For this reason, our steam locomotive has been repaired several times.

If this problem is not solved, it is probably impossible to use such structures of rubber tires and rims."

Jingmu simply confirmed it and understood the problem.

At the beginning, steam locomotives used very bulky iron wheels, which had poor anti-slip effect and poor shock absorption performance.

So although the prototype car was sold at the beginning, it was basically left at home and not used.

I bought a lonely one.

In order to change this situation, Jingmu has also made a lot of efforts in the past few months.

The rubber tires on the permanent bicycle gave him great inspiration.

So he immediately found the Rubber Research Institute of Guanshishan Academy and asked them to help research a rubber tire suitable for steam locomotives.

Michelin originally intended to further expand the scope of application of rubber. The two sides hit it off and quickly came up with a tire available for use.

After four tires were installed on the front and rear of each steam locomotive, the performance immediately changed dramatically.

I personally took Jingmu, which had a test drive of a steam locomotive, and I had a very deep understanding of this.

So even if there were several problems in succession, he did not give up this idea.

"I remember at the beginning, this bolt was only the size of a little finger, but now it is thicker than a thumb. Do you still break frequently?"

Lao Hansan looked at the steam locomotive lying on the ground with a painful face.

"Yes, it's still not possible. I think it should be caused by the poor quality of the steel. I also communicated with Aniu Special Steel Workshop to see if they can provide better quality steel to make bolts, but they don't have the confidence to meet the needs of steam locomotive hub bolts."

"Since the wheel hub bolts we made ourselves cannot meet the requirements, let's talk to other bolt and nut workshops in Chang'an City. As long as anyone can make bolts that meet the requirements, we are willing to produce advanced ones.

Also, you have to think of a way to simulate and confirm whether the strength of the wheel hub bolts meets the needs. You cannot install it directly on the steam locomotive for real car confirmation every time. This is a bit expensive."

As a boss, Lao Hansan is naturally very concerned about the various expenses of the steam locomotive workshop.

During this period, repairing prototype cars has almost become the largest expense in the workshop, so he naturally has to find a way to cut it.

"I heard that the iron smelting workshop in the King of Chu Mansion has a set of equipment to test the performance of steel. I want to see if it can also be introduced to our steam locomotive parts for performance testing."

Although Lao Hansan's words made people feel uncomfortable, Jing Mu also knew that he really needed to think of ways to reduce costs.

Otherwise, if the steam locomotives were not sold on a large scale, they would lose tens of thousands of yuan first, and Lao Hansan might not have been able to persist.

After all, no family’s money fell from the sky.

"Since you already have an idea, then go and communicate quickly. At worst, we can ask the craftsmen from the Iron Smelting Workshop of the King of Chu Mansion to help us transform.

As far as I know, His Highness the King of Chu supports this behavior that will not cause any impact on the industry of the King of Chu’s Mansion.”

...

"Shopkeeper, I heard that the steam locomotive workshop of the Laoniu Transportation Team purchased a batch of bolts from us today?"

In Chang'an Precision, Chen Tie suddenly came to Chen Xing's office.

"Yes, I heard that their steam locomotives have never been able to officially mass-produce due to the problem of wheel bolts. The Jingmu shopkeeper was so anxious that he was about to get angry.

These days, they have traveled all the workshops that can make bolts in Chang'an City and bought a bunch of bolts to go back for testing."

For Changan Seiko, a niche market like steam locomotives, which can't be niche, is obviously a bit disliked.

According to Chen Xing's inference, if the steam locomotive can be sold a hundred vehicles a year, it will be so powerful that it cannot be more powerful.

Even if you can only sell dozens of vehicles a year, it is very likely.

In this case, how many bolts can be used?

"It should be just like what you said. There are many people in the workshop city waiting to see their jokes, thinking that Lao Hansan and Jingmu are not doing well in transportation, but they are fantastic about what steam locomotive to make.

Now I spent a lot of money, but I was stuck on a bolt."

While greeting Chen Xing, Chen Tie thought about how to convince him to accept his opinion.

"The four-wheeled carriages are becoming more and more mature and have better performance. The iron lumps like steam locomotives obviously have no future. Why are you suddenly interested in this?"

Chen Xing knew that Chen Tie had been sleeping day and night in the workshop during this period, in order to find the best special steel for the formula.

"Shopkeeper, I think this is the best opportunity to make our bolts famous. Although we have not found the most perfect formula, the bolts made from special steel are now many times better than before.

If we can use the steam locomotive as a test platform to make our new bolt stand out, this news will surely spread among various workshops soon.

At that time, other workshops that have special requirements for bolts will definitely take the initiative to come to us Chang'an Precision.

This is definitely a great thing.”

Obviously, Chen Tie can't wait to withdraw from the new bolts made of special steel.

"But what if our bolts can't meet the requirements?"

"If this happens, it will not have any particularly big impact. Because they have purchased a batch of bolts from our workshop for testing, and these bolts are destined to not meet the requirements.

At that time, the new bolts we provide will definitely perform the best even if they cannot meet the requirements."

Chen Tie said this and Chen Xing was moved.

Changan Precision is facing relatively high competitive pressure now, so it is naturally the best to have a store-holding product.
