Chapter 65: tester

　　 Cheng Kailong is not empty words.
　　 He felt that with Wang Bu'an's contribution, it was no problem to get a special medal.
　　 The current leaders of the party and the country attach great importance to those who have made merit. Never let the other party feel wronged.
　　 Unfortunately, Wang Buyan is not a member of the army.
　　 If he was a member of the army, he would be first-class merit.
　　 In peace times, if you want to get first-class merit, the difficulty is definitely going to heaven.
　　 However, Cheng Kailong believed that Wang Bu'an had every reason to obtain first-class merit.
　　 Of course, based on the principle of low-key, the honor Wang Buyan has won cannot be made public for the time being. As one sentence says, your name is unknown, and your deeds will last forever.
　　 "How did you do it?" Cheng Kailong asked slowly.
　　 "Confidentiality." Wang Bu shook his head slowly.
　　 Of course he can’t say that this is technology from the planet Cybertron, not of people on earth.
　　 is not unwilling to say. There is no need to explain.
　　Aliens?
　　 Do you think I am a three-year-old child?
　　 "Well, please continue to help us make some test items." Cheng Kailong did not continue to ask.
　　 "No problem." Wang Buan promised.
　　 He reached out his hand and brought the information.
　　All data are stored in an encrypted U disk.
　　 This kind of U disk uses a special password. If outsiders want to crack, the U disk will be destroyed automatically.
　　 Cheng Kailong entered the password, and the U disk opened smoothly.
　　 Data transmission begins.
　　 Robot Wizard No. 1 checked all the data.
　　 Immediately, the first machine started to start. Various alloys with different shapes and properties are produced in an orderly manner.
　　The heavy alloy ingot was then hoisted onto the workbench of the 100 million-ton hydraulic press.
　　 The first thing to forge is a flat alloy steel plate.
　　 is five meters in length and width. The thickness is ten centimeters.
　　The alloy ingot is placed on the large workbench.
　　100 million ton hydraulic press immediately began forging. Repeated forging fifty times.
　　 Similar alloy plates, Cheng Kailong needs fifty pieces in total.
　　 includes different thicknesses. There are 10 cm, 20 cm, 30 cm, 50 cm and so on.
　　 They are all prepared for testing. Including artillery shell shooting, aerial bombing and so on.
　　The most important thing is of course to test the shooting of armor-piercing projectiles and depleted uranium projectiles.
　　The previous steel drills have proved that the materials used are very hard. Various weapons cannot cause damage. However, the shape of the steel drill is too special to match oneself.
　　After the alloy plate, it is a large and small composite alloy plate. Various shapes. The thickness is also completely different.
　　Some are the front armor of the tank, and some are the side armor.
　　Some are front armor of armored vehicles, and some are side armor.
　　 There are also tank tracks, road wheels, etc.
　　 not only tests the forging capability of hydraulic presses, but also tests the processing capability of multi-axis CNC linkage machine tools.
　　 For example, the front armor of the tank is folded in many places. The processing is very difficult. There are strict regulations on inclination and angle. The slightest difference is a thousand miles away, absolutely not sloppy.
　　In the previous tank, the turret was egg-shaped, which could bounce off ordinary shells. But in the face of a new type of armor-piercing projectile, there is nothing that can be done.
　　 Therefore, the latest tanks, including the 99th modification, are all composite armors with polyhedrons in appearance.
　　 In addition, there is a set of high-power diesel engine blocks.
　　 If the guess is correct, it should be the engine of the 99 modified tank.
The 99 tank before 　　 had an engine power of only 1200 horsepower. It was later increased to 1500 horsepower.
　　 However, the latest engine is not perfect. The performance is not very stable and the reliability is insufficient. In many exercises or trainings, 99 reforms have seen squatting.
　　 As for the older 96-style, there are more lying nests. In the final analysis, it is the reliability of the engine.
　　 The processing of diesel engine cylinder blocks is more complicated and requires a whole set of tools.
　　 However, for 100 million ton hydraulic presses and 10-axis CNC linkage machine tools, it is actually a trivial matter.
　　 does not need the main workbench at all. The auxiliary worktable is directly extruded.
　　 Ten-axis linkage extrusion, easy and beautiful.
　　The material used is a secondary high temperature corrosion resistant alloy. It is resistant to heavy pressure of 3600 tons, high temperature resistance of 3600 degrees, and 360 tons of centrifugal force.
　　 "Are you... several axis linkage?" Cheng Kailong asked curiously.
　　 "Ten axis." Wang Bu'an answered honestly.
　　 "So many?" Zhang Kailong looked stunned.
　　 "In fact, it is an enhanced version of five-axis CNC linkage, each axis is divided into two." Wang Bu'an said under the guise.
　　 "Oh." Cheng Kailong was finally able to accept it.
　　 Ten-axis linkage, so awesome.
　　 Especially in the field of heavy industry, the difficulty of five-axis linkage is very high.
　　 The five-axis linkage requires high sensitivity. Then, in terms of strength, it is naturally impossible to avoid some weakening. Therefore, processing small parts is fine, but processing large parts is difficult.
　　 It happens that the crankshaft, propulsion shaft, propeller and so on of the ship are all curved, and they must use five-axis CNC linkage.
　　 At the same time, the five-axis CNC linkage machine tool is also required to have a very powerful force.
　　 Otherwise, how can those giants of dozens of tons or hundreds of tons be easily cut into shapes?
　　 This hydraulic press of Wang Bu'an is simply amazing.
　　 "Let's take a look at the blades of the propeller." Cheng Kailong took out the data on the bottom of the pressure box.
　　 "Okay." Wang Bu'an is still an understatement.
　　 No. 1 robot wizard reads data.
　　Data shows that the requirements of this propeller blade are very high.
　　 It is more than four meters long and weighs more than five tons.
　　Such a huge propeller, most of the time, are used on the 100,000-ton giant ship.
　　The general huge wheels are all four shafts and four propellers. It is four propeller shafts and four propellers. Only a few are six-axle and six-propeller. It is six propulsion shafts and six propellers.
　　Forged propellers require special materials. It cannot be a general alloy. High-temperature corrosion-resistant alloys are also not suitable. It can only be a very special copper alloy. For example, nickel aluminum beryllium bronze alloy and so on. Otherwise, all year round immersion in water will cause various problems. Special coatings are also used on the surface of copper alloys. It is best to have a certain degree of toxicity, so as not to entangle marine life.
　　As far as any country is concerned, the processing technology of propellers is at the top. Regardless of cost, only quality.
　　Because of high-speed rotation, the pressure and resistance are very large. Even small bubbles (called cavitation in professional terms) may cause irreversible damage to the propeller blades. Many of the propellers are sturdy and can't even cause damage from bullets, but they are damaged by small bubbles.
　　 When forging propeller blades, cavitation damage must be considered.
　　Any blade needs to be forged and tempered repeatedly to achieve the ultimate quality.
　　 Can Wang Bu'an do it?
　　 Cheng Kailong's heart is actually bottomless.
　　 "If you can't do it, don't force it." Cheng Kailong said, worried about gains and losses.
　　 "It's okay." Wang Bu'an was very sure.
　　 This is not Hang Ma’s propeller, the requirements are not so high.
　　 Now he is ready to forge Hang Ma's propeller. There is just no chance.
　　 The raw material for forging the propeller comes from the No. 8 machine.
　　It mainly produces various high-performance copper alloys.
　　 nickel-aluminum-copper alloy, combined with special metal elements such as beryllium, palladium, niobium, molybdenum, and chromium, is the best raw material for forging propellers.
　　 A huge heavy copper alloy came off the production line and was hoisted immediately.
　　 It was placed on the main workbench of the 100 million-ton hydraulic press and repeatedly forged. The parameter set by Wang Bu'an is five hundred times.
　　The copper alloy ingot was forged into a flat plate, and then sent to the second workbench for extrusion.
　　 The ten-axis CNC linkage machine tool starts. One extrusion molding.
　　 No cutting is required. No further processing is required.
　　 After squeezing several times in a row, and then grinding, the surface of the blade is very smooth.
　　 The whole process took less than twenty minutes.
　　 Cheng Kailong looked at all this dumbfounded, unbelievable.
what is this?
　　 These are the propeller blades of the giant wheel!
　　 Generally speaking, its processing time takes at least one month. Even three months.
　　 However, Wang Bu'an only took twenty minutes.
　　 Twenty minutes!
　　 One extrusion molding!
　　There is no need for correction at all~EbookFREE.me~ no fine-tuning.
　　 "You..." Cheng Kailong stopped talking.
　　 He has a lot of problems.
　　 But I don’t know where to start.
　　 After all, he is not a professional. He just knows a little about everything. The real experts are still on the way.
　　 Because of the meeting, Cheng Kailong unexpectedly became the first person to contact Wang Bu'an. In order to hurry up, he asked him to reach an agreement with Wang Bu'an as soon as possible, and strive to send samples for testing as soon as possible. If the quality of the sample is up to standard, it must be ordered in large quantities. No, it's a super large batch. The number will be staggering.
　　 In the past time, we have left too much homework. Now, it must be made up.
　　 But, the speed is so fast, is the quality really guaranteed?
　　 Let the data speak.
　　 Seeing the night fall, the rain gradually stopped.
　　 Two hours of rain ended.
　　All the samples needed by Cheng Kailong are also ready.
　　 A group of Dongfeng trucks hung up to take pictures, pulled the tarp, and drove slowly into the industrial park.
　　 People who drive and cars are all dressed in casual clothes. But anyone with a discerning eye can see it. They are all soldiers. That kind of trained temperament can't be concealed.
　　 They are responsible for transporting all the samples away.
　　 Some heavy samples require large-scale hoisting machinery.
　　 "Aren't you from Chengfei? What do you want so many test products for?" Wang Bu'an asked in a low voice in confusion.
　　 "Have I ever said that I am from Cheng Fei?" Cheng Kailong said solemnly.
　　 "No..." Wang Bu shook his head slowly.
