Monster Factory

A croissant hammer was quickly brought in, and if not stopped by an elderly worker next to him, the worker with the croissant hammer must have been a flying hammer, smashing the master down the stairs.

Dropping this little old man was everyone's idea, including Li Huaxing.

Isn't that what strikes people?

Perfect in their eyes, like children's products, there is nothing to be praised for?

“You get down here!” There are already grumpy people, and they start yelling angrily.

“Come down, we have the guts to pull the racket apart by comparison, by comparison, by precision. ”

It didn't matter before, nothing touched his expression and disappeared from the masterful face.

Instead, the arrogant, eagle-like, sharp eyes reveal a high and superior gaze.

In the voice of anger of the crowd, the master of ingenuity spoke.

In a word, let them instantly become bombarded silence.

“The frame beam on both sides, I can only look at it and see that it has a linearity error of more than 0.07 mm 1 m. ”

“12 meters long beam, what do you see distorted? ”

“Distorted into a reptile, tell me, what is this qualified product? ”

The anger of all was stuck in the throat, in the words of the master of ingenuity.

Straightness error of the girder...

The 12-metre long beam is a whole, and the larger the part, the harder it is to process. The Master of Sophistication means that the two beams are distorted and distorted, and no metre is straight.

The master of sophistication is right. The beams milled out by large milling machines have a certain precision error in themselves. When lifting to the frame for welding, because the high temperature thermal deformation produced by welding makes the beams more accurate.

Errors here can be measured by workers, but within a certain margin of error, workers feel that this will not affect the vehicle.

But how does this little old man know that?

The chief engineer Wang Zhuan couldn't help but have a red face. This error he understood was one thing, and was instantly pointed out as another.

Though it feels fine. But this error is also a little too big, putting it on a regular sedan, definitely a nonconforming product.

They wanted to know that, unfortunately, the master of ingenuity had not been given the opportunity to ask them questions.

“And look at your engine reducer housing. Is that round? I draw a circle by hand, and it's more precise than that. ”

“This is ridiculous. Look at the spacing between the screw holes in your reducer casing. Is it saving money or saving time?” Master Skilled waves the horn hammer: “I'm sure it won't take more than a year and the reducer housing is about to start lubricating oil. ”

“This is rubbish, rubbish designed without experience. ”

The reducer housing is cast iron, but the size of this cast iron is huge. And the deceleration gear inside doesn't have to be in contact with the housing, so it's not too precise...

As long as the drilling accuracy of the position connected to the crankshaft of the engine is controlled, the tolerance of the space at the beginning of the design is large enough, and the extra rights leave room for lubricants.

If from the point of view of efficiency, the chief engineer Wang Jiao is not wrong in this design.

The spare parts of a mining vehicle are as large as the sea, and in order to save time and costs, it is common practice for many heavy industry enterprises to minimize unnecessary links.

But!

An ingenious master's sentence suddenly made chief engineer Wang Jiao realize that he had made a terrible mistake and was also the most classic dogmatic mistake.

There was nothing wrong with him putting the original 190-ton reducer on the 240-ton scale.

But he actually had to punch 48 screw holes to design the enclosure seal, which was also magnified to 240 tons, without any increase.

Larger size means larger spacing between the same number of screw holes.

As the spacing increases, the fastening capacity naturally decreases. Over a long period of time, the sealing pads must be severely worn, causing many domestic commonly committed problems - oil spills.

Everyone was shocked by a cold sweat, chief engineer Wang Zhuan looked pale, subconsciously touched the top pocket, pulled out the notebook he was carrying, trembled and quickly recorded this terrible mistake.

When he writes this down in a fast-track way that only he can understand. Chief engineer Wang wiped a cold sweat and developed a breath of cold air.

Then he turned around and discovered that all the workers around him had actually taken out their notebooks or cell phones, and his heart was still palpitating to record this fatal defect.

It can be said that without today's masters of ingenuity to flaunt them, they want to discover this neglected detail and can only organize technicians to study it once the product has been delivered to the customer, used for a year or two, and exploded by the ensuing questioning phone.

Unfortunately, at that time, their brand reputation was impacted, crowned unreliable, oil spills, design problems, and so on.

The more complex the product, from design setting to true maturity and reliability, it needs to undergo a series of improvements and have suffered countless losses to achieve perfection.

The words of the masters of ingenuity directly led them to step away from a great pit.

“Looking at your hydraulic lifts, the four main hydraulic lifts are so close together, do you want to go through the trunk? ”

“Looking at your turn again, I ask you to measure the ruler and measure its spacing...”

“Take a look at your hanging design…”

The master of ingenuity stood on a tall console, talking constantly, without any pause, any word he said, at this time in the ears of those below, has become all the best notes in the world.

Even those mouth-watering garbage, inappropriate oral meditation, became so delightful.

They became the hearers at this time, and the disdain in their hearts had been transformed into a strong admiration to the limit, and a worship that no ten cows could pull out.

shā shā ~

These are several technicians who record sounds quickly with the paper and pen they carry with them.

They've forgotten I'm intoxicated, and even the words garbage and disqualification are written down without a word.

Li Huaxing's performance at this time is really not strong enough. He has already stood next to a technician. Reviewing every word like a draft, he is ready to wait for the transcript to be finished, immediately take a copy back to the office and study it in closed doors.

“He... he's not the doorman, he's the doorman...” The bodyguard standing there like a stake, his brain is down, Bill Gates is here and he can't solve the code.

“Looking at the telex system you designed, I can only describe it in garbage. The gear gear of the DC motor is obvious...”

“Cough cough cough cough cough cough" Ye Qingyi listened to the ingenious master criticized the core technology of the mining truck, DC motor transmission system, instantly swinging eyes with hints.

The skilful master's sudden silence prompted the monkeys to hurry as a group of technicians and workers who had washed their ears ready to listen.

“Master, go on.” The worker who tried to smash him down with a hammer has now become a better model for learning than three good students, and the phone directly turns on the video.

“Maestro, go on, don't stop.” The chief engineer Wang Jian is climbing the construction bracket at this time, and he wants to gather next to the master of ingenuity and listen to the teachings up close.

“Master, there are many technical defects in our garbage product waiting for you to explain. ”

“Yeah, yeah.” The next few technicians nodded wildly and threw their previous anger into the Java Country.

What an international joke, this esteemed old man, an absolutely world-class master, and possibly even a top technician at Caterpillar, is worth a decade of blindness.

“It's all rubbish. It can't be finished.” The master hummed twice, walking along a frame as spacious as a street to the rear bridge where a giant DC motor was plugged.

A silver-white drive shaft that is one metre thick and eight metres long and bright as a mirror is revealed in the eyes of a master of sophistication.

The master skilfully jumped onto the rear bridge and slammed the giant power axis with a horn hammer in his hand.

Clang ~

A crisp, crisp metal impact sound is transmitted to everyone's ears.

No one dares speak, even breathing is temporarily closed.

Because of the ingenuity of the master, he is closing his eyes and putting his hands next to his ears to make listening letters.

When the loud impact sound disappeared, the master skilfully jumped to the other side and hit the power axis again.

“Can this also be called a power axis? There are dark wounds in the middle, and the problem lies with it. ”

The master of ingenuity returned to the construction frame, stretching his neck towards the workers and technicians waiting to be taught: “Who is responsible for producing the power shaft of such garbage? ”

Together with Li Huaxing, everyone looked at a technician wearing a grey work suit.

They already have an unconditional trust in the abilities of masters of ingenuity. With a hammer alone, they can hear and recognize dark wounds in the spindle. What kind of magic trick is this?

“Boss... I...” said the younger technician, blushing and vomiting, "The accuracy of the power shaft is not... no problem, I promise. ”

“Every step of the workers operates strictly according to the production process and the precision is not… there is a problem. ”

“Master Qiao!” The chief engineer Wang Zhuan constantly grabbed silver and grey hair on his head at this time is equally puzzling: “If the spindle is not precise enough, it should be directly stuck, not a single step, but it has clearly run for more than 10 kilometers. ”

“Your low demands for precision make me despair…” The master shook his head.

“The problem, however, is not precision, although precision meets the minimum walking requirements. ”

“The material used is too garbage, the processing method is too garbage, the quenching is too garbage.” Skillful master touched a power shaft: “DC motor in the middle of the power shaft, the heat generated during work gradually accumulates, resulting in a slight thermal expansion of the power shaft. ”

“You have certainly not calculated the coefficient of thermal expansion of the spindle, and you have overestimated the quality of this DC motor. ”

Thermal... coefficient of thermal expansion...

The chief engineer's genius was struck by lightning and his body trembled violently, more excited than a monk who had once been enlightened.

One word and wake up from the dream!

No wonder everything was normal when it started and it took more than 10 kilometers to get stuck.

When they drove the mining truck back to the workshop and unloaded eight large pieces of research, the temperature of the power shaft had dropped long ago, and no precision error could be detected naturally.

When producing 190 tons of mining vehicles, it is directly purchased foreign mature technology, a problem that has never arisen.

Autonomously developed 240-ton, spindle material has also been made of 190-ton spindle material, so the culprit is naturally DC motor.

By working hard on the radiation of DC motors, you can solve the problem of jamming.

So that's how it is, so that's how it is.

Large mining vehicles are engines that drive the generator to work and then generate huge amounts of electricity to drive DC motors on the rear axle.

DC motors for 190-ton mining vehicles, and 240-ton DC motors, are necessarily two designs.

So we just need to redesign the DC motor...

How to design……

The chief engineer Wang Cai was just about to scratch his ears and scratch his cheeks, his hands just touched his hair and suddenly drowned and slapped his thighs.

The world-class master is right in front of him, and he still wants to get an axe to design the motor...

Haha ~

It's just that their chairman is going to bleed badly this time!
