Try to guess what sealed in the first picture?
- Rolls of stock
Dear readers, before your eyes cars Renault Logan and Sandero, and other items of pride auto industry, but only at the initial stage of production. It will go in my reportage about the company, where they make a blank for body parts. However gauge only the workpiece is not limited, but I'll still only about her.
2. Weight of iron kruglyashey than 6 tons
3. The branch line is laid directly on the shop floor, wagons I stop here for unloading …
- The rolls in the car
5. With a 20-ton bridge crane, which is able to deliver its cargo to almost anywhere in shop
- Overhead crane
7. Console decoiler rolls. Designed for unwinding rolls of metal and keep it safe during camp
- Console decoiler roll
8. The plant installed a longitudinal line …
- Slitting coils
9. and longitudinal-transverse cutting coils
- Line longitudinal cross cutting
12. The screen on the control line, you can control the basic parameters of the product
- Control panel
It is possible to cut the original hire for all sorts of sizes required for the release of all the body parts of cars. Now with this production supplied the Avtoframos (Renault), Gorky Automobile Plant, as well as for the production of Hyundai in St. Petersburg, the plans were for the supply of VW-Audi, maybe they have already been realized.
Existing equipment is loaded in a fairly high degree and not stand idle. Therefore, the reserve increase productivity factory workers see in accelerating the process of readjustment when switching from one to the other dimensions of the workpiece, which takes quite a long time.
13. The blank is folded and packed in bundles. Next after stamping, coloring and other operations, these bits of iron will turn to car body.
14. Came across this and other products of the shop — metal profile, which is used in construction
Actual question — how to ensure the quality of the metal, going to manufacture body parts. First, the automaker itself indicates it needs the properties and characteristics of the metal and clearly indicates the desired vendor rental: will it Severstal, MMK, or may need to supply rolls from abroad. Matching specification long and difficult process.
Secondly, the plant has its own laboratory with modern equipment. It tested in many ways the samples taken from each (!) Roll. If for some reason the metal is not being tested and is used for the production of products where quality is not imposed such high demands.
A look into the lab.
15. Universal testing machine for tensile, compression and three-point bending
You can also perform the following tests on low-cycle fatigue of materials:
* Determination of the number of cycles to failure of the sample;
* Test to determine the long-term strength of relaxation / creep;
* The definition of permanent deformation;
* Test the springs in compression / expansion;
- Universal Testing Machine
17. Machine for grinding samples
- Machine for grinding samples
18. Furnace for heating samples
19. Optical emission analyzer chemical composition of metals and alloys
- Optical emission analyzer
20. The hardness tester to
measure the hardness of materials by Rockwell and Super Rockwell
21. Test machine for sheet metal drawing
- Test machine for sheet metal drawing
22. and the results of its work.
- The sample in the testing machine by drawing sheet metal
23. Next to the laboratory is located warehouse samples from all batches produced metal for a long time. In case of doubt, the test can be repeated
- Storage of samples
