Accompanied by Hughes Field, Yang Weiping took Qiu Fang to inspect the processing workshop of spindles, cranksets, steel rings, spokes, brakes, tires and other parts, starting from the chain workshop.

In the spacious and bright workshop, Chinese and foreign employees wearing work clothes are busy in their respective positions in an orderly manner.

Hughes Field's bicycle factory, which originally had three mature chromium-molybdenum steel bicycle production lines and more than 2,400 skilled workers, has now changed to produce aluminum alloy bicycles, and the structural adjustment of the process flow of each parts processing workshop does not require major surgery.

Each workshop is actually a parts processing branch, and all parts, including the production of rubber tires, are all self-produced. Unlike the bicycle factory in later generations, there are a large number of upstream and downstream parts suppliers to outsource.

Coming out of the tire workshop, Yang Weiping, Qiu Fang, Hughes Field and other people came to the frame processing workshop.

Except for the supervisor of the workshop who came out to receive the inspection of the company's senior management, the rest of the workers performed their duties in their posts, and were not significantly affected by the arrival of the boss.

The main processes of frame processing are welding and grinding, as well as surface heat treatment.

Liu Gangsheng is a veteran welder with more than 20 years of experience in electric welding, and has also worked in the Pegasus Bicycle Factory Manufacturing Company for eight years, and is now the leader of the welder group in the frame processing workshop.

The company's products were suddenly transformed, the frame was replaced by aluminum alloy from the original chromium-molybdenum steel, and the welding process was naturally greatly adjusted.

Although the company has conducted surprise training on the welding of new frames, in the actual work process, the welders will still habitually use the original experience to solve some problems in the welding process.

Not long after Yang Weiping walked into the frame processing workshop, his deep frowning brows were not relaxed.

Seeing that Yang Weiping was not talking and laughing like he had when he inspected those workshops before, Hughes Field couldn't help but ask softly, "Yang, is there something wrong?"

"Yes, and the problem is very serious!" Yang Weiping nodded without hesitation and replied: "Field, please ask the workshop supervisor to stop all the welders immediately, their welding techniques are not right, if this continues, the frame will not pass the non-destructive testing at all!"

Seeing Yang Weiping's expression so serious, Hughes Field dared to slack off, and immediately ordered the workshop supervisor to notify all the welders who were working to stop.

Liu Gangsheng was instructing an apprentice to weld at this time, and when he heard the greeting of the workshop supervisor, he quickly clapped his hands and signaled everyone to stop what they were doing.

At this time, Liu Gangsheng saw the young man in his twenties who was standing next to the British boss in work clothes, with thick eyebrows and deep furrows, and walked towards him with a solemn face.

"Yang Dong, this is Liu Gangsheng, the leader of the welder group, an old welder in the factory. Huang Fuda, the workshop supervisor in his forties, diligently accompanied Yang Weiping with a smiling face.

"Master Liu, hello!" Yang Weiping nodded expressionlessly, said hello, and then said in a deep voice: "Please call all the welders in your frame workshop, including the apprentices, to come over, I have something to say to you!"

From Director Huang's words, Liu Gangsheng heard that the young man in front of him turned out to be one of the bosses of the company, and seeing the young boss's face as if he was not very happy, Liu Gangsheng couldn't help muttering in his heart, could something have happened?

Under Liu Gangsheng's loud greeting, more than 40 welders in the frame processing workshop all gathered around.

Yang Weiping looked left and right, walked to a workbench, and jumped up neatly.

"Hello everyone, masters!" Yang Weiping looked around at the welders below with a slightly soothing face, "The frame is the largest and most core important component of a bicycle. The quality of the frame is directly related to the safety performance of the whole bike. …,

I know that many of you present here are old welders and technicians with many years of work experience, but I need to emphasize to you again today that the welding of aluminum alloy frames is essentially different from the welding of chromium-molybdenum steel frames!

Previously, the company has trained you and thinks that you are all old welders, with strong receptivity, and should be able to adapt to the new process quickly. However, I just saw that the vast majority of you still use the original welding techniques and experience to weld aluminum alloy frames, and I am really disappointed and sad!

However, I don't blame you, it's us who don't have the training in place, and I apologize to you!"

Speaking of this, Yang Weiping bowed deeply to Liu Gangsheng and other welders and technicians.

Liu Gangsheng was taken aback by Yang Weiping's bow, and he knew that the matter must be very serious.

Hughes Field was also seen by Yang Weiping's actions, and his expression became extremely solemn, and he glared fiercely at Huang Fuda, the workshop supervisor.

"Today, I take this opportunity to focus on the welding technology of the aluminum alloy frame and share it with you!" Yang Weiping's slow voice rose again, and he said loudly: "When the aluminum alloy is welded, it will form an aluminum film on the surface of the base metal that is difficult to weaken, hindering the fusion of the base metal and the filler metal, and then affecting the performance of the weld.

There is no color change when aluminum is converted from solid to liquid state, and it is difficult to control the molten pool during the welding process, and it is easy to cause molten metal to collapse. If the operation method is not proficient, it will also produce welding defects such as slag inclusion, unfused, porosity, and welding nodules. This directly leads to the quality of the weld, which in turn affects the quality of the overall frame. ”

Speaking, Yang Weiping jumped down from the workbench, walked to a frame, picked up the welding gun, opened it, and explained on the spot while demonstrating in person: "THE THICKNESS OF THIS THIN-WALLED ALUMINUM ALLOY PIPE IS ONLY 1.6MM, SO WHEN WELDING, THE SIZE OF THE WELDING TORCH TIP EXPOSED, THE GAS FLOW, THE CURRENT SIZE, THE WELDING POSITION, AND THE ANGLE OF THE WELDING GUN HAVE RELATIVELY STRICT REQUIREMENTS, PLEASE PAY ATTENTION TO MY OPERATION ......"

……

In the frame workshop, Yang Weiping personally gave a very vivid on-site training class to more than 40 old welders, which not only impressed Liu Gangsheng and other old welders, but also made Hughes Field, who had been accompanying him, also admired.

When he came out of the frame shop, Hughes Field pulled Yang Weiping curiously and asked, "Yang, do you know anything else besides electric welding?"

"Of course, Field, we are engaged in mechanical manufacturing, and if our own skills are not strong, it is easy to be fooled by the employees under our hands. Yang Weiping replied very seriously: "There is an old saying in Huaxia that iron still needs to be hard. If you know a lot about quality inspection and know what kind of system you use to control procurement quality standards, you will not be taken advantage of. ”

"Yes, in fact, I have always attached great importance to product quality, but I didn't expect that just such a negligence would almost be lost. Hughes Field nodded with a sigh and said, "Yang, the ISO9000 quality management system you came up with is very good, and I think our bicycle factory should also introduce this system." ”

"It's a must!" Yang Weiping nodded and replied: "McKinsey people are still studying this system, and when the pilot is successful in Tiangong Aluminum, our Giant will be the first beneficiary of this management system." In the future, all our factories and companies will adopt this system and standards. ”

"McKinsey & Company was really lucky this time, Young, with your cunning, you can't do them this big favor for no reason, right?" asked Hughes Field with a smile.

"Hehe, of course you have to leave a name for doing good deeds. Yang Weiping smiled proudly: "One million Hong Kong dollars, plus this system, I made Americans willingly sell 12% of the shares." ”…,

"Yang, you are so cunning and shrewd!" Hughes Field exclaimed in an exaggerated and strange voice: "McKinsey's global assets are worth at least $100 million, and you have earned another $12 million in assets so easily, and you can make money faster than the bank's money printing machine!"

"It's just an asset on paper. Yang Weiping shrugged his shoulders disappreciatively, "My agreement with the Americans indicates that the 12 percent of the shares cannot be transferred to the outside world. ”

Although Yang Weiping said this in his mouth, he was secretly proud in his heart, a fool will transfer, and controlling McKinsey in the future is my ultimate goal.

The two walked and chatted, and soon arrived at the transmission manufacturing workshop.

The 18-speed transmission designed by Yang Weiping is another core component of the upcoming mountain bike in addition to the frame.

The function of the bicycle transmission system is to change the speed of the vehicle by changing the cooperation of the chain and the gear discs of different front and rear sizes.

The size of the front chainring and the size of the rear chainring determine how hard the bike rotates the pedals. The larger the front chainring, the smaller the rear chainring, and the more laborious it is when pedaling.

The smaller the front chainring and the larger the rear chainring, the more relaxed it is when pedaling. Depending on the rider's ability, the bike can be adjusted by adjusting the size of the front and rear chainrings, or to cope with different road sections and road conditions.

The so-called several stages of bicycle transmission refers to the number of front large disc teeth multiplied by the number of rear flywheel teeth, mountain bikes are usually the first 3 large discs, and the rear flywheel six, seven, eight, and nine speeds, multiplied by 18, 21, 24, and 27 speeds.

Gear machining belongs to precision machining, and the reason why Yang Weiping attaches great importance to this is mainly to come and see the batch of precision gear machining machine tools that Hughes Field bought back from the UK.

According to the different types of gears to be processed, gear processing machine tools can be divided into two categories: cylindrical gear processing machine tools and bevel gear processing machine tools.

Seeing the brand-new gear hobbing machines, double-cutter head straight bevel gear milling machines, extended cycloid bevel gear milling machines, CNC forming gear grinding machines, high-speed dynamic balancing machines and other precision machine tools installed in the two passages in a neat and orderly manner, Yang Weiping couldn't help but secretly praise that Hughes Field is indeed a supernatural power.

These gear processing machine tools can basically be regarded as the world's first-class precision gear processing equipment, and these equipment are not in Yang Weiping's hands now.

The last time the precision CNC machine tools knocked from the hands of the Germans were all general equipment, and there was no such professional gear processing machine tool among them.

However, gear processing is an extremely important link in the engine industry chain, and it is also an indispensable and important field for basic industry.

Now, Hughes Field has helped Yang Weiping fill this shortage!
