*Compared with steel molds, it has good thermal conductivity and does not stick to molds, which can ensure uniform mold *temperature distribution during work, will not cause mold cracks due to local high temperature, and will not cause cold sweat, *exfoliation, and wrinkles in stretched products. phenomenon.
*Economic and practical, long life of core rod material.
*The core rod material processing technology is simple. Compared with steel molds, no direct heat treatment is required for direct polishing. Therefore, the heat treatment cost is reduced, the mold processing time is shortened, and the number of stretching times can be reduced and the cost of the mold can be reduced.
Our Tee Production Tee Shaping cold forming machines Pipe and elbow mandrel head materials are generally ZG1Cr18Ni9Ti, ZG3Cr20Ni14, ZG1Cr25Ni20Si2, ZG0Cr20Ni25, etc., the high temperature strength and wear resistance have gradually increased, and the price has also increased accordingly.
Pushed elbow mandrel head is divided into single curvature, double curvature and multiple curvature according to the radius of curvature.
For single-curvature, double-curvature, and multi-curvature mandrels, the thrust force is gradually reduced, and the production cost is gradually increased. According to the cross-sectional shape, it is divided into two types: circular cross section and elliptical cross section. The circular cross section is simple to make and the cost is low, but the ellipticity and thinning rate of the elbow are too large. Different, the ellipse and thinning rate of the push elbow are small.
Heiyan chose a mandrel with an oval cross section. According to whether or not there is a shaping section, it is divided into a mandrel head with a shaping section and a mandrel head without a shaping section. The Tee Production Tee Shaping cold forming machines Pipe mandrel with shaped section is complicated to manufacture, high cost and long use time; the mandrel without shaped section is simple to manufacture and low cost.
Tee Production Tee Shaping cold forming machines Pipe Basic Introduction:
HY Tee Production Tee Shaping cold forming machines Pipe is a kind of mandrel used for pipe expansion and extubation, and a mandrel mold that promotes the forming of steel pipes.
The hot-expanded steel pipe forming process uses a special pipe expanding machine, a core mold (commonly known as a mandrel) and a heating device (commonly known as a heating coil), so that the blank set on the mold is moved forward by the pusher, and is moved during the movement. Process of heating and expanding. The diameter of the used pipe is smaller than the diameter of the pipe to be obtained. The deformation process of the blank is controlled by the core mold, so that the compressed metal at the inner arc flows to compensate for other parts that are thinned due to the diameter expansion, so that the wall thickness is uniform. Heat expanded steel pipe.
Performance characteristics of our Tee Production Tee Shaping cold forming machines Pipe:
The hot-expanded steel pipe forming process has the characteristics of beautiful appearance, uniform wall thickness and continuous operation, which is suitable for mass production. Therefore, it has become the main forming method for carbon steel, alloy steel and stainless steel pipe expansion. The opposite process is extubation. The thicker steel pipe is drawn into a thinner pipe by a process, and the steel pipe produced by this process is called drawing pipe. Materials are carbon steel, stainless steel and alloy steel. After the steel pipe undergoes the thermal expansion process, its material is unchanged. Welded pipes and seamless pipes can be applied to this process!
