Stamped parts are manufactured through stamping with minimal material consumption. They are lightweight, have good rigidity, and after plastic deformation of the sheet metal, the internal structure of the metal is improved, resulting in an increase in the strength of the stamped parts.
⑵ Stamped parts have high uniformity in size with the same module and good interchangeability. It can meet general assembly and usage requirements without further mechanical processing.
During the stamping process, stamped parts have good surface quality and a smooth and beautiful appearance because the surface of the material is not damaged. This provides convenient conditions for surface painting, electroplating, phosphating, and other surface treatments.
In the continuous production of modern industry, flanges are inevitably affected by factors such as medium corrosion, erosion, temperature, pressure, and vibration, resulting in leakage problems. Due to errors in the processing dimensions of the sealing surface, aging of the sealing components, and improper installation and fastening, flange leakage is easily caused

Flange, also known as flange disc. A flange is a component that connects pipes to each other, connected to the end of the pipe; Also used for flanges on equipment imports and exports, used for connecting two devices, such as gearbox flanges. Flange connection or flange joint refers to a detachable connection composed of flanges, gaskets, and bolts connected to each other as a combined sealing structure. Pipeline flange refers to the flange used for piping in pipeline devices, and used on equipment refers to the inlet and outlet flanges of the equipment. There are holes on the flange, and bolts tightly connect the two flanges. Seal the flanges with gaskets. Flanges are divided into threaded connections (threaded connections), welded flanges, and clamp flanges. Flanges are used in pairs. For low-pressure pipelines, threaded flanges can be used, while for pressures above four kilograms, welded flanges can be used. Add a sealing gasket between the two flanges and tighten them with bolts. Flanges with different pressures have different thicknesses and use different bolts. When connecting water pumps and valves to pipelines, the corresponding flange shapes are also made for the parts of these equipment, also known as flange connections. Any connecting parts that are bolted together in two planes and enclosed at the same time are generally referred to as "flanges", such as the connection of ventilation ducts, which can be called "flange type parts". However, this connection is only a partial part of a device, such as the connection between a flange and a water pump, so it is not appropriate to call the water pump a "flange type component". Smaller components such as valves can be called "flange parts". Reducer flange, used for connecting motors and reducers, as well as connecting reducers with other equipment. The flange connection method is to first fix two pipes, fittings or equipment on a flange, add flange pads between the two flanges, and fasten them together with bolts to complete the connection. Some pipe fittings and equipment already come with flanges, which also belong to flange connections. Flange connection is an important connection method in pipeline construction. The flange connection is easy to use and can withstand high pressure. Welding flange, socket welding flange, threaded flange, flange cover, neck welding ring loose flange, flat welding ring loose flange, ring groove surface flange and flange cover, large diameter flat flange, large diameter high neck flange, eight shaped blind plate, welding ring loose flange, etc.

Flanges are divided into threaded connection (threaded connection) flanges, welded flanges, and sleeve flanges. Low pressure small diameter flanges have threaded flanges and sleeve flanges, while high pressure and low pressure large diameter flanges use welded flanges. The thickness of flange plates and the diameter and quantity of connecting bolts vary for different pressures.
1. Install bed and car panels, chamfers, and skirt corners.
2. Punch the screw hole and then tap the tooth (diameter 24mm)
3. According to different models of end plates, countersunk drilling and perforated flushing are used.
4. Strip steel cutting with fixed length, welding, and horn pressing.
5. The semi-finished end plate is crimped or welded with the corresponding skirt plate, and the finished end plate is completed.
Flange fittings are a type of welded fittings. This type of pipe fitting is used to match the pipeline. There are both processed and unprocessed ones. Some castings are made by casting all the flanges together. And the welding is processed later. The factory can process it, and it can also be processed on the construction site. There are large and small head flange fittings, as well as elbow and tee flange fittings. Its materials are also diverse, including carbon steel, alloy steel, stainless steel, etc.

⑴. Reasonable mold design. In the progressive die, the arrangement of cutting sequence may affect the accuracy of stamping part forming. For the cutting of small parts of stamped parts, a larger area of punching cutting is usually arranged first, followed by a smaller area of punching cutting to reduce the impact of punching force on the forming of stamped parts.
⑵. Press down on the material. Overcoming the traditional mold design structure, a material gap is opened on the discharge plate (i.e. when the mold is closed, the material can be compressed). For key forming parts, the discharge plate must be made into an embedded structure to facilitate the solution of grinding (pressure) damage caused by long-term stamping at the pressing part of the discharge plate, which cannot compress the material.
⑶. Add strong pressure function. Thicken the size of the unloading insert pressing part (normal unloading insert thickness H+0.03mm) to increase the pressure on the material on the concave die side, thereby suppressing the flipping and twisting deformation of the stamped part during punching.
⑷. Trim a sloping or curved surface at the end of the convex die blade. This is an effective method to reduce punching force. Reducing the buffer cutting force can alleviate the tensile force on the material on the concave die side, thereby achieving the effect of suppressing the flipping and twisting of stamped parts.
⑸. In daily mold production, attention should be paid to maintaining the sharpness of the cutting edges of the convex and concave molds. When the cutting edge wears out, the tensile stress on the material will increase, leading to an increased tendency for the stamped part to flip and twist.
⑹. Unreasonable or uneven punching gaps are also reasons for the flipping and twisting of stamped parts, which need to be overcome.

Flat welding flange refers to a type of flange that is connected to a container or pipeline using fillet welds. It belongs to any type of flange. When designing, check the integrity of the connection between the flange ring and the straight cylinder section according to the integral or loose flange. There are two types of flange rings: those with necks and those without necks. Compared with neck welding flanges, flat welding flanges have a simpler structure and lower material consumption, but their rigidity and sealing performance are not as good as neck welding flanges. Flat welding flanges are widely used for connecting medium and low pressure vessels and pipelines. Flat welding flanges are suitable for pipeline systems with relatively low pressure levels, where pressure fluctuations, vibrations, and oscillations are not severe. The advantage of flat welding flanges is that they are easier to align during welding assembly and are relatively inexpensive, thus they have been widely used. A gasket is a circular ring made of a material that can undergo plastic deformation and has a certain strength. Most gaskets are cut from non-metallic plates or made by professional factories according to specified sizes, and their materials include asbestos rubber sheets, asbestos sheets, polyethylene sheets, etc; Metal gaskets made by wrapping non-metallic materials such as asbestos with thin metal plates (such as white iron sheet and stainless steel) are also used; The issue of flat welding flanges has always been a topic of concern for people, as it relates to the production costs or economic benefits of companies and enterprises. Therefore, the sealing principle of flat welding flanges is constantly being improved and improved.
