Welcom to Channel One Minute Manfacturing. This time, let's take a look at the manufacturing process of giant flanges in a forging factory. The great wisdom of a flange forger, they use the simplest machinery to create perfect workpieces. And this is a large workpiece forging factory in Qingdao, China. If you are interested, plase check the whole manufacturing process detials in this video's description.
Thank you.
Step1. Unload the steel, and tons of vibrating steel are placed on the cutting platform. Workers use measuring tools to accurately control the size of the blanks, and then the cutting machine cuts the steel attached to the tree poles into forging raw materials of different sizes.
Step2. The worker drove a forklift and inserted the mechanical arm into the giant furnace, and took out the red-hot raw materials from the forge.
The forklift transfers the raw steel blanks to the forging platform, and then the hammering of the steel blanks begins.
After many forgings, the steel blank, which was originally a cylinder, was hammered into the shape of a wheel cheese.
Step3. Places a homemade hemispherical stamping tool in the center of the steel blank. This tool is used to locate the hole in the middle of the flange.
As the broken hammer continues to fall, the steel embryo is deforming at a speed visible to the naked eye. With each hammer blow, the steel embryo becomes a little thinner, and the crisp oxide layer on the surface is also shaken off.
The purpose of this is to expand the area of the steel embryo and speed up the thinning of the steel embryo.
Under the powerful hammering of the forging machine, the steel embryo became thinner and thinner, and its area gradually expanded.
The shape of the steel embryo changed from a cheese wheel to a Xinjiang baked bag, which made people have a desire for delicious food.
Step4. When the steel blank is broken to a certain size, the worker puts a trapezoidal iron nail in the center, and then the heavy hammer falls.
In order to prevent the broken parts from sticking, workers will also sprinkle iron oxide and coal powder at the impact location.
Step5. Turn the steel embryo over, took away the iron ingot with the holes, replaced it with a bow and arrow, placed it at the center of the steel embryo, and used the power of the forging hammer to continuously impact and hammer the center of the steel embryo.
A piece of remaining material in the center of the steel embryo was cut off.
Step6. Use a thigh-thick iron rod to pass through the center hole of the steel embryo, and then transport it to an iron frame. After placing the steel embryo, start the air forging hammer and continue hammering the outer ring of the steel embryo.
Distributed in different stations, and cooperated with the mechanical arm to rotate the steel blank to make it forged more evenly.
Step7. Repeated beating with a broken hammer, the steel blank was forged into a ring shape, and then placed back on the forging platform. The worker uses steel pliers to pick up a square iron block and place it next to the ring.
Step8. After the flat surface of the ring was forged, the worker changed to a wedge-shaped tool and measured the forging size with a steel ruler. Then he could use the wedge-shaped tool to forge the flat surface of the ring.
Step9. Forge the step surface of the giant flange. After a while, the prototype of the flange step surface was forged. Then replace it with a larger wedge-shaped iron block to deepen the shape of the flange step surface.
After ninety-nine and eighty-one hammer forgings, the forging of the prototype flange was completed.
Step10. Drove a forklift to put the flange steel blank into the furnace for reheating. After 20 minutes, the flange steel blank is heated, and the heated steel blank is transferred to the ring rolling machine with a forklift. With the support of the ring rolling machine, the flange steel blank can be quickly forged into shape.
Step11. After the flange steel blank is properly positioned, the ring rolling machine is started. The flange steel blank moves close to the center column of the ring rolling machine, and the ring rolling machine is rolled. The ring machine gradually applies pressure to die-cast the flange steel blank.
As the rolling machine rolls, the flange steel embryo gradually expands and its shape becomes more and more square.
Step12. After an hour of die casting, the shape of the plastic flange was finally forged. Then open the protective cover of the ring grinding machine and use a forklift to take out the formed flange bow and arrow. The red flange ring is like an oversized gold bracelet.
Step13. When they came to the machine shop, the workers fixed the rough flange plate to the machine tool, and then started the machine tool to start fine machining of the flange plate.
The processed flange became smooth and flat.
