In general, some metal sheets are formed by hand or die stamping to produce plastic deformation, forming the desired shape and size, and can be further welded or a small amount of mechanical processing to form more complex parts.
Stamping process is a kind of metal processing method, which is based on the plastic deformation of metal, and USES the mould and stamping equipment to apply pressure on the Sheet Metal, so that the sheet metal produces plastic deformation or separation, so as to obtain the parts (stamping parts) with certain shape, size and performance.
Stamping forming technology in automobile body manufacturing process occupies an important position, especially large automobile body covering parts, because the most complicated shape, the structure of large size, some still space curved surface, and surface quality requirement is high, so use stamping processing method is used to make these parts can't be matched by other processing methods.The cab of the truck, the Sheet Metal Parts in the front of the truck, the van board, the various body coverings of the car and the various skeleton of the bus are almost all made by stamping.

The device has six characteristics: convenient transportation and installation, small footprint, good stability of the polymer liquid concentration, health and environmental protection, high degree of automation, low prices. The device has a mother liquor formulation design capacity of 5 to 60 m3/h, concentration error within ±2%, and strong on-site adjustment capability. Since it was put into use in mid-September this year, after nearly three months of trial operation, the device has shown its advantages of low failure rate, uniform dispersion of concentration, and low operating cost, and is particularly suitable for the dispersion and dissolution of small-scale or site-constrained polymers. , has a good application prospects.
It is understood that polymer flooding technology is an ideal oil flooding method to improve the recovery of old oil fields, but it has the characteristics of high investment, high cost, and high risk. Water jet technology is a new technology developed in the past 30 years. It has been applied in such sectors as coal, petroleum, metallurgy, chemical engineering, machinery, and water conservancy, and is mainly used to cut, crush, and clean materials. The water jet polymer dispersing device uses the principle of variable jet pressure. After the water is ejected at high speed by the ejector, a partial vacuum is formed around the nozzle to generate a negative pressure, which provides power for the polymer powder to be discharged, and at the same time, high speed water flow can provide enough Energy, forcing the mixing of polymer dry powder and water, avoids clotting and "fish eye" phenomena.
Water jet polymer dispersion device
After more than one year of joint efforts, the Shengli Petroleum Administrative Bureau’s General Machinery Plant and Gudong Oil Production Plant successfully developed and developed a dispersion-dissolving device for armored water jets with a polymer mother liquor speed of 15 m3/h. 9#-1 injection polymerization station in the second district of Dongfang Oilfield.
