Cold Forming Elbow Machine Pipe Fitting Elbow Mould Die Mandrel
Our Cold Forming Elbow Machine Pipe Fitting Elbow Mould Die Mandrel 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 Cold Forming Elbow Machine Pipe Fitting Elbow Mould Die Mandrel 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.
And the mandrel and Cold Forming Elbow Machine Pipe Fitting Elbow Mould Die Mandrel material used in our factory has the characteristics of wear resistance, bending resistance and strong impact resistance, and the surface is bright and clean, suitable for the extrusion of copper, iron, aluminum, zinc, stainless steel and other metals.
Advantage of Cold Forming Elbow Machine Pipe Fitting Elbow Mould Die Mandrel are as follows:
*High hardness and abrasion resistance surpasses the die steel, and does not strain the surface of the machined part.
*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.
