Butt weld flange forging process. For the butt weld flange forging process, according to the different forms of movement of the forging die, the forging process can be divided into roll forging, ring rolling, inclined rolling, swing rolling, rolling transversal wedge, oscillating rotary forging and other types. Among them, twist rolling, twist twist forging and ring rolling can be processed by precision forging. In order to improve the utilization rate of materials, roll forging and cross rolling can be used for pre-processing of thin materials, so it is difficult to improve the precision of forgings. Therefore, it is necessary to control the direction of movement of the forging die and the stamping process by a computer, so that forging products with complex shapes and high precision can be obtained with low forging force.
Since liquid metal can form a hollow cylindrical free surface during the casting process, hollow castings can be produced without using a core structure, greatly simplifying the production and processing of pipe and sleeve castings. The casting process is simplified, the production efficiency is high. , and the cost is low. When rotating, due to the phenomenon of centrifugal force generated by the liquid metal, the welding flange processing technology can effectively improve the ability of the metal to fill the mold. Therefore, for those thin-walled alloys and castings with poor fluidity, forging can be used.
For the cold forging of the welded titanium flange production blank, the corresponding deformation and work hardening will occur, which will cause the forging die to bear a large load. Therefore, we need to use high-strength steel during the forging process. Dies are used, and at the same time they are treated with a film of hard lubricant that prevents wear and adhesion. In addition, in order to prevent defects such as cracks in the welded flange blank, it is necessary to perform an intermediate annealing treatment to improve the overall deformation resistance of the welded flange.

St. Louis Fed President Bullard said yesterday that due to the banking crisis, financial pressures have increased in recent weeks, but they can be controlled through regulatory policies rather than interest rates. This remark seems to imply that the Federal Reserve will continue to raise interest rates, and will not change this position because of the risk events that broke out in the bank before. However, judging from the probability of raising interest rates implied by the federal funds rate futures, the probability of keeping interest rates unchanged at the current May rate meeting is close to 60%. Therefore, the price of precious metals continued to fluctuate and rebound yesterday. Moreover, precious metals still have bargain-hunting value in the current market where there are great differences in the path of future interest rate hikes, and at the same time, there are many uncertainties in the future economic outlook.

On the evening of March 27, Ningde Times issued an announcement stating that the company recently reached a supply agreement for a 450MWh battery energy storage project with HGP, a battery energy storage project development company. The two parties will also establish a long-term partnership to promote the implementation of up to 5GWh utility-scale and distributed energy storage projects to meet the growing demand for renewable energy in Texas, USA.

In the chassis parts, many parts are also applied to the stamping process, such as some guard plates, swing arms, sub-frames, etc. Many problems in the stamping parts in the later period are caused by the unreasonable design in the early stage, so as a qualified product design engineer
