Corrosion thermometer tells metal pressure processing

Metal pressure processing is to point to by external force, make the metal billet produces plastic deformation, and achieve the required shape, size and mechanical performance requirements of magnetic flap thermometer processing method. It can be divided into rolling, drawing, forging and stamping four categories.

( 1) Rolling: make the metal blank across the middle of the rotating roll gap, compression and produce plastic deformation processing method called rolling. Rolling billet production is mainly is the billet ( Ingot) 。 Rolling metal blank section was reduced, the length increases, thereby gaining a variety of cross-section shape of rolled products, such as key board, profile, etc. Steel produced by rolling method, has high productivity, variety, the advantages of easy to realize mechanization and white move, therefore 85% 90% of key material is steel rolling workshop production. Metal in the recrystallization rolling called hot rolled over falling in degrees, on the contrary, known as the cold rolling.

( 2) Drawing: in special equipment, general metal blank through a touch of die hole ( The die hole section is less than the original cross section of rolling piece blank) Pull to make metal billet has the processing method called drawing of plastic deformation. After drawing products is mainly the anti-corrosion thermometer all kinds of fine wire and thin wall pipe and all kinds of special shape of cross section profile. The method marked characteristics is the product obtained has high degree and high quality of the surface, so often used for rolling piece ( Reprocessing pipe, bar, in order to improve the quality of products. Drawing production for 10 processing low carbon steel, nonferrous metals and their alloys. ‘ Have is usually carried out under a cold, so also known as the cold drawing.

( 3) Forging, the metal billet heated to high temperatures, borrow satin hammer blow or press head compression and make the metal processing method called forging blank shape. Use forging method can get the finished product, also can get bad MAO for machining and rolling. In accordance with the different tools, forging can be divided into manual forging ( Such as the hammer, anvil, hammer, etc. ) And mechanical forging ( Such as steam hammer, hydraulic press, etc. ) 。 According to the characteristics of metal deformation, forging divided into two categories: free forging and die forging. Free forging is refers to the floating ball thermometer hot metal artifacts in height by compression and can freely on the horizontal extension processing method. It is suitable for single piece and small batch production complex shape of forgings. Die forging products is sell light, size accurate, can be mass production.

( 4) Stamping: on special equipment ( Usually punch) , place the sheet metal in the die, the separation and deformation caused by stamping process of stamping processing method is called. It often blanking, punching, bending, deep drawing, such as processing method, separation and forming the basic process can be divided into two categories, such as blanking, punching processing way is a separate class. Bending, deep processing ways is forming. Stamping process can direct the production of various parts and blank. Because of its is usually carried out under a cold, so it can be called cold stamping.

rolling steel cross section shape and size of the total is called the specifications of steel. According to the characteristics of the steel shape steel can be divided into sections, key board and steel tube three categories. Among them, the glass tube thermometer under section according to section can be divided into the simple section steel, complex shape of section steel and deformed steel.

H section steel is a kind of new varieties of steel in last decade, gained the name for the section shape of English letter H. For the difference between beams, sometimes referred to as wide flange beam. H-beam section shape and size is reasonable, the section modulus, bending, torsion, good mechanical properties such as compressive strength, can greatly reduce the construction quality. H yi's wide range of USES, usually for high-rise buildings, large Bridges, the machine structure EGv magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer
