The web is still stamped, and the weight of the No. 45 iron block is burned red and white in the furnace, and the large pliers are pulled out and thrown into the mold.

"Empty, empty!"

The metal block gradually turned into a discus, and then the discus was clamped, and the bottom was thrown down to punch the mold, and the huge hole in the middle was chiseled out alive.

The next step is a simple repair, and so on, the whole process fully demonstrates the violent aesthetics of the machine, and a group of students who are in contact with casting for the first time are enthusiastic.

More than a dozen cylinders have all been cast, the first one has been thoroughly cooled, and the crane lifts the cylinder into the lathe to open the rough.

The entire internal cavity is cleaned with a long-arm cutter, and the two sides of the end turning tool are positioned to size. The surface of the outer drum is hardly turned, it is simply aligned.

The next step is for the shaft head to enter the lathe to process to the semi-finished product size, the web finish-turned shape, and the two are combined with direct spot welding and the finished cylinder. qδ

"Zizi Zi ......"

The web, the shaft head, and the cylinder are completely combined, and with the sparks of oxygen welding shining, the whole workpiece slowly becomes one. Wait until the workpiece is completely cooled, and the welded parts are processed on the surface of the machine tool for the second time to ensure the concentricity of the shaft heads on both sides.

"Master Qi, in the last step, you can directly use a planer to cut out the grooves on the surface, and then wait for me to hang the glue."

Looking at the workers in strict accordance with their own process routes, Ji Donglai nodded, Da Qizi breathed a sigh of relief in his heart, as a skilled worker, the most worrying thing is to follow a leader who doesn't know anything to command blindly.

Whether in state-owned factories or private enterprises, there is the kind of second pen that rings in the ears of skilled workers. Say that you are not right here, that is wrong, and give you a random command.

If you don't follow his requirements, you say that you don't respect the organization's opinions, listen to their opinions, and process the waste products to say that your level is not good.

Ji Donglai just watched the whole drum processing process, without a word of nonsense, whether the other party understood it or not, this respect for the workers was respectful.

"Okay boss, you don't have to follow, we will tell you that we have all finished processing, it is estimated that it will take three days to complete all processing!"

It was already completely dark, Da Qizi wiped the beads of sweat on his forehead, and Ji Donglai nodded.

The rubber compound of the rubber manufacturer is also working overtime to process, Ji Dong came to greet Ding Aixing, whispered a few words in the other party's ear, and the other party hurriedly drove to SJZ.

At noon the next day, Ding Aixing and the vehicle transporting the rubber material arrived almost simultaneously.

"Brother Donglai, is this it? It's not a good thing to buy!"

Ding Aixing said and took the release film in his hand from the car, Ji Donglai took a brief look and nodded, beckoning the workers to poke the rubber on the car into the workshop.

"It's good that the rubber is thick enough! The shaft head is connected to the reducer, and a few of you follow me to hold ......."

Reaching out and pinching the rubber, Ji Donglai was still very careful to let his subordinates take out a piece to make a test piece, and he took all his subordinates to start winding the whole roll of rubber on the processed metal roller.

Bearings are installed on both sides of the drum with surface lines, the adhesive sprayed on the surface has all dried up, and the reducer above the roller drives the roller shaft to slowly begin to roll the rubber sheet on the surface of the roller to ensure that the film and the roller are sealed and fitted.

According to the drawings, the entire surface of the steel rod needs to be wound with fifteen thicknesses of rubber, Ji Donglai pressed the head of the rubber sheet into the hemp surface of the steel rod, and then started the reducer connected by the rubber roller.

With the slow start of the reducer, the film between the driving wheel and the driven wheel is gradually straightened, and gradually the rubber sheet becomes tighter and thicker. On the fifteenth floor, Ji Donglai nodded, and the reducer stopped.

Ji Donglai smashed the rubber sheets directly together, and then covered the entire surface with a release film, wound them on one side, and drove the air to one side with a metal rod on the other.

"On the mold, pay attention to the torque of the clamping bolt, after twenty-five Nm!"

The rubber on the surface of the entire metal rod was wound, and Ji Donglai gave an order, and the cylinder mold was snapped. The bolts are locked, and the worker feeds the entire hanging rubber roller into the furnace.

If it is repeated, ten

The five rubber rollers finally entered the furnace, accompanied by workers to seal the surface of the furnace, Ji Donglai set the furnace temperature at 200 degrees, and the power was started.

"Wait three hours to eat roast duck, just look at it occasionally, as long as it doesn't drop the temperature by accident!"

The process of hanging rubber rollers is not difficult, but the whole process is very slow, time-consuming and laborious, and the practice of large factories is without exception.

Ji Donglai still doesn't plan to apply the machining center in the next process, because he drove away Livitt, almost all of Swell's molds were assigned to him by Ji Donglai, and occasionally those who don't like processing were handed over to Zhang Yu.

Now there is a golden rooster that lays its own eggs, and there must not be a little time to be idle, plus the elevator factory is constantly sending workpieces over, and it is necessary to ensure that the machine tool is good and the steel is used on the blade.

"Give this drawing to Master Qi, find the bevel gear in the scrap we received, and then two chains, and design a tool holder telescopic mechanism, my design is like this, specifically let them look at it, to the effect that it is like this!"

Ji Donglai used UG to simulate a machine tool machining, similar to an automobile differential, and Ji Donglai added a chain-driven cam on the surface to drive the turning tool holder to ensure that the turning tool holder can be expanded and contracted on the outer surface of the roller according to the requirements.

The surface fixation of the main tool holder was all handed over to a few old technicians on the site for design, and the rest of Ji Donglai was too lazy to do it, after all, now that there are engineers, Ding Aixing promised to find a few masters, and a few people got the drawings and immediately gave a thumbs up.

"This little boss is not easy to fool, a two-zero bed can study three axes for you, this alone can make our group admire, you can do it!"

Da Qizi and the old lathe worker looked at the drawings, and finally handed the drawings to the old technician, who took a sip of water with a large tea jar, lit a cigarette, and took the little apprentice into the scrap iron workshop.

Beckoning everyone to start looking for waste gears and waste shafts according to the reduction ratio.

It is not far from Tianjin Port, most of the scrap iron is from the scrap ship parts of Tianjin Port, the quality of the metal is not said, and soon similar parts are found, and the processing and transformation have no problem for the old mechanics.

Ji Donglai almost didn't participate, and when the rubber roller came out of the furnace, Ji Dong came to the scene to take a look.

"Eh, I'll go, it's like an egg leaking, it's a soup!"

Almost every rubber roller has a rubber flow out of the side, with the car pushing out of the furnace, Ji Donglai carefully inspected each rubber roller.
