Forging manufacturer: What are the characteristics of forgings and what are the inspection items?
Forging factory: forgings the development prospects of this industry is very good, because in the use of the time for the enterprise to bring more benefits, so favored by the customers, in order to let everyone more familiar with it, understand its characteristics, better for the benefits of the enterprise, the next we will talk about it and its related trivia points, hope to bring more people to help, so that it brings more benefits.
Forging manufacturer: first of all, we know that the weight of the forgings range, the use of it from as small as a few grams to as large as hundreds of tons, and higher quality than the castings, this is because the mechanical properties of forgings than castings, can withstand the action of large impact forces and other heavy loads, so where some important, relatively large force parts will be used forgings for construction. And the use of forgings also saves raw materials. For example, the static weight of 17 kg crankshaft used in cars, in the use of rolling material cutting forging, its chips to account for 189% of the weight of the crankshaft, which is a serious impact on the use of the effect, but if the use of forgings, it is only 30% of the chips, and can also shorten the machining of 1/6 of the working hours. In particular, HSS milling cutters need to be re-forged. Because only after the HSS rolled material is re-forged to meet its use requirements. Then, under the premise of ensuring the design strength, forgings compared to castings, its weight is very light, which reduces the weight of the machine itself, especially for transport, aircraft, vehicles and word Zeus aerospace equipment have a very important significance. And the productivity of forgings is very high, for example, in the use of two hot-die forging presses die forging radial thrust bearings, it is possible to replace 30 automatic cutting machine tools. Especially when using top forging automatic machine to produce M24 nuts, six-axis automatic lathe productivity of 17.5 times. This greatly improves the productivity and indirectly increases the revenue of the enterprise. This is because forged forgings not only save more raw materials, but also more machining hours, while the flexibility of free forging is also great. Therefore, the forging method is widely used in some repair plants to produce various accessories.
Forging factory: then how to check the forgings, what items are needed to check it, let's continue to look down it. General forging shape size with steel ruler, calipers, sample plate and other gauges for inspection; complex shape of the die forging parts available scribing method for inspection. Then we can observe the forging fracture organization state inspection method with the help of metallographic microscope, can check the carbide distribution, grain size and decarburization depth and other items. If the forging surface if there are cracks, pressure wounds, folding defects, generally with the naked eye can be found. Sometimes the crack is very small, folded at the depth of the unknown, can be observed after the clear shovel; if necessary, the flaw detection method can be used to check.
