Stamping technology of stainless steel forging
Stamping technology is the most common and mature forming technology for producing stainless steel forgings with the characteristics of large workpiece size and high precision. Stamping process can not only obtain thicker stainless steel semi-finished forgings, but also obtain thin wall stainless steel forgings with complex shapes and accurate sizes. Stamping process of stainless steel forgings includes cold blanking, hot pressing, cutting and shearing.
1. Cold stamping technology for stainless steel forgings
Cold stamping technology is a common forming technology for stainless steel forgings, and generally applies to thin wall workpieces. Generally speaking, with the aid of tools and molds, the surface parts of stainless steel semi-finished forgings are press-formed at room temperature. At the same time, this applicable process has the properties of high production efficiency, rich product models and low cost.
2. Hot forging technology of stainless steel forgings
Hot forging technology is a kind of forming technology for stainless steel forgings which is suitable for high-strength stainless steel materials and complex transformable parts. This technology can greatly increase the grain size and mechanical properties of the workpiece and obtain finished workpieces with high accuracy.
Generally speaking, hot forging of stainless steel forgings is hammer forging, that is, the use of impact energy to the workpiece by compacting or stretching to achieve the purpose of forging. It can be divided into two categories according to the state of the workpiece: one is hot upset forging, which uses compaction force to reduce the thickness of the workpiece to obtain forgings with complex shapes; the other is hot stretching forging, which is used to stretch the thickness of the workpiece to obtain forgings with simple shapes.
3. Cutting and shearing technology of stainless steel forgings
Cutting and shearing is an important kind of forming technology for stainless steel forgings. Generally speaking, two kinds of equipment are used: guillotine shear and rolling shear. It is mainly used to chop stainless steel semi-finished forgings into stainless steel forgings with certain shapes and sizes.
At the same time, cutting and shearing process of stainless steel forgings can save a lot of cost and time. It can produce stainless steel forgings of different shapes, and the formed stainless steel forgings all have uniform texture, which is suitable for further processing and manufacturing.
In short, the stainless steel forging stamping technology has great advantages, such as high efficiency, low cost, high precision and energy saving. At present, the stamping technology of stainless steel forgings is widely used in the production and processing of stainless steel forgings and has become an indispensable process.
