Forging is a method to process metal. The advantage of this method is that it can increase the performance of the metal itself while forging, because the fault and gap inside the metal billet will be removed during forging, which is actually to increase the bonding degree of metal particles inside the metal during forging, so that the excess impurities in the metal can be removed during forging.
Under the condition of modern technology level, almost any kind of metal material can be made into forgings or parts by casting method, just with different degrees of difficulty. Today, the forging accuracy is getting higher and higher, which can reach or even exceed the general accuracy level of mechanical processing. Such as various cold and warm kneading standard parts, precision forged gears, precision forged blades, precision forged shafts, etc; The component of forgings is becoming larger and larger. With the appearance of large hydraulic presses, the disorder of forgings has also been significantly improved due to the presentation of multiple parting surfaces. Hollow pipe fittings with Laifu Line can now be directly formed on special forging equipment.
The design of forging pre forging cavity is very important. The pre forging steps are mainly used for pre forming and material distribution, so that the material can be evenly distributed in the final forging cavity, and the positioning is accurate, without burrs and insufficient filling. It has the advantages of high material utilization rate, material saving and consumption reduction. Due to the non non edge forging and the reduction of machining allowance, the consumption of forging materials is significantly reduced. The die has simple structure, convenient disassembly and assembly, and long service life. Under this structure, the inner core of the lower die is a vulnerable part. In order to facilitate the replacement of the female die, its pressure ring adopts a bolt structure to facilitate the loading and unloading of the female die. High production efficiency and good forging quality.
In fact, the forging factory is an essential element of the forging equipment required in a city. In many cases, the forging factory has neglected to pay attention to the difficulty of flange plate with high-pressure method. The forging processing factory is very quality oriented and has a variety of flange products. Therefore, if you want a forging factory to be reliable, you must go to a forging factory for flange products. If you have good suggestions or opinions, please call at any time.
The inspection items can be determined according to the pressure and mechanical property requirements and corresponding grades:
1. Flanges with design pressure less than 10.0MPa and forgings with similar geometric dimensions shall meet the requirements of Class II or above;
2. Forgings with design pressure greater than or equal to 1.6MPa shall meet the requirements of Class II or above;
3. The design pressure is greater than or equal to 10. 0MPa medium and small forgings shall meet the requirements of Grade III, and large forgings shall meet the requirements of Grade III or IV;
4. Forgings with extreme or highly hazardous toxicity of the medium used and forgings with section size greater than 300mm shall meet the requirements of Grade III or IV.
