First, the cutting method blue, laser cutting the inner and outer diameter of the flange and the thin and thick disk on the plate, and then the production and processing of the anchor bolt hole and water line. The flanges that are manufactured and manufactured in this way are called the cutting method blue. The larger diameter of the flanges is limited to the width of the medium and heavy plates.

Third, the volume production method blue, using a medium-thick plate to cut a strip and then roll into a round processing technology called production, mostly used in the production of some large and medium-sized flanges. After the production is successful, the electric welding is carried out, and then the flattening is carried out, and the production process of the water line and the anchor bolt hole processing process is carried out.

Second, the basic process of free forging: When freely forging, the shape of the cast steel is gradually forged according to some basic deformation process. The basic process of random forging is upsetting, lengthening, punching, bending and breaking. 1 rough: rough is the operation process of quenching the original billet in the radial direction to reduce the aspect ratio and enlarge the section. This type of process is common in forged drive gear blanks and other disc-shaped cast steel parts. The upset is divided into two types of upsetting and partial forging. 2 Pulling length: Pulling length is a forging process that increases the length of the billet and reduces the cross section. It is generally used to produce shaft parts such as lathe spindles and crankshafts. 3 punching machine: the forging process of punching the buried hole or not burying the hole on the blank with a punch. 4 Bending: The forging process of bending the blank into a necessary viewing angle or appearance. 5 Distortion: The forging process in which the partial relative rotation of the billet is required to be rotated. 6 laser cutting: the forging process of cutting the blank or removing the material.

4. Die forging, die forging is called solid model forging, and the heated blank is placed in a forging die fixed on the die forging machine to form a shape. 1 The basic process of die forging The whole process of die forging process: cutting, heating, pre-forging, final forging, punching, laser cutting, aging treatment, shot blasting. Common processing techniques include upsetting, lengthening, sheet metal bending, punching, and forming. 2 Common die forging machine equipment Common die forging machine equipment has die forging hammer, hot die forging press, flat forging machine and friction press. Popularly speaking, the forged flange is of higher quality, usually produced according to die forging, the crystallization mechanism is fine, the compressive strength is high, and the price is also expensive. Both forged flanges and forged flanges are attributed to the common manufacturing methods of flanges. The compressive strength of the components that must be applied is specified. If the regulations are not high, the milling method can be used.

Carbon steel flanges are manufactured and manufactured in different manufacturing and R&D processes using different methods and processing techniques. According to the processing methods and basic principles, they have critical use values and effects on different levels. The specific manufacturing process adds the necessary elements to enhance the characteristics and use value of the carbon steel flange, mainly showing excellent application characteristics and use value. The key to carbon steel is that the physical properties are the carbon content of the carbon in the steel, and the steel usually does not contain a lot of aluminum alloy elements, sometimes called ordinary carbon steel or alloy steel. Carbon steel is also called alloy steel, and refers to iron-carbon aluminum alloy containing less than 2% carbon content WC. In addition to the carbon contained in carbon steel, carbon steel usually has a small amount of silicon, manganese, sulfur, and phosphorus. The safety protection of the carbon steel flange in the specific manufacturing and manufacturing process, the matters and methods that must be paid attention to during the production and manufacturing, etc. The first welding of a polygonal ring shell with irregular cross-section or closed on both sides The multi-edge fan-shaped shell is internally filled with working pressure material, and is subjected to gas pressure. Under the external pressure effect, the cross section gradually changes from an irregular pattern to a circle, and finally becomes an annular ring shell. According to the necessity, an annular ring shell can make different carbon steel flanges, which can present key features in specific applications. The machining process is suitable for the production of stamping elbows. The diameter of the punch and the nominal diameter of the stamping elbow exceeds 1. The large and medium-sized elbows of all specifications and models are ideal for the production of large and medium-sized carbon steel galvanized pipe fittings at this stage.

Nowadays, carbon steel flanges have been used a lot. At the time of application, people have thought about it. What kind of carbon steel flanges are used to produce and process them?

1 expansion method: This is placed on the outside of the tube to put vulcanized rubber, the upper side is reduced with a punch to make the water pipe convex shape; the other way is the hydraulic machine is inflated and formed, the liquid is filled in the south of the water pipe, and the liquid is pressed against the liquid. The water pipes are drummed into the necessary design.

2 Forging method: use a swaging machine to give the water beam end or a unit to the electric butterfly valve to make the diameter beat. The common type forging machine has twisted, connecting rod and roller type.

3 Rolling method: The outer core of the tube is pressed by the roller on the outer periphery, which is used for the production and processing of the round edge.

4 rolling method: the same flat without a mandrel, moderate to the side edge of the thick-walled tube.
