Stamping elbow of cold stamping and hot stamping steel stamping elbow two suppliers, usually selected based on cold pressing or hot stamping material properties and device capabilities. Before stamping, tube placed on the lower die, the inner core and the end of the tube into the mold, the mold pressing downward movement began stamping elbow, through supporting role within the outer mold and die making constraints elbow shape. Compared with hot push technology, the appearance of the inferior quality of the former stamping; stamping elbow while forming outside the arc in tension, no other parts of the excess metal to compensate, so the wall thickness at the outer arc of about 10% to about thinning . However, as for single-piece production and low cost, it is used for stamping elbow process small quantities, thick-walled elbow manufacturing. Standard and materials introduced stamping elbow elbow international standard is now the U.S. national standard ANSIB16.9 and 16.28. The standard diameter size range is 1/2 to 80 〃 〃, 〃 less than 24 are generally used as a raw material of stainless steel seamless pipe prices stamping elbow, 26 〃 80 〃 are then welded with steel after stamping. Wall thickness up to 60mm, the smallest to 1.24mm. Steel is the most widely used carbon steel (20 #), alloy steel and stainless steel, a total of 24 steel. CrMo steel boiler used as 15Cr, the amount is relatively large. Tee, outside diameter range of 2.5 〃 〃 -60, -60 from 26 〃 〃 welding tee. Wall thickness of 28-60mm. Head size specification, first said the bulk of the conventional specifications, say small head size, the bulk of minimum 0.75 〃, 〃 head minimum 0.5, the bulk of the maximum 60 〃, head up to 48 ,20-60 〃 〃 as welding, wall thickness 2.8 -45mm. Stamping elbow materials require some special raw materials for production of these materials to conduct rigorous selection and control of raw materials to choose the right stamping steel 90 ° elbow, otherwise there would be no production of stamping elbow quality assurance. Stamping bends head stamping material variety, widely used applications, are forming a large-scale high-tech industry group, has a very broad market prospects and extremely important strategic significance. Stamping material classification according to different classification criteria can be divided into different categories, according to the use of performance can be divided into microelectronic materials, optoelectronic materials, sensor materials, information materials, biomedical materials, eco-materials, energy materials and smart ( smart) materials, these materials have different stamping performance, showing good value in use in different fields and industries. 】 【Stamping elbow, carbon steel elbow supplier stamping, welcome to Hebei million gold piping supplied by Hebei billion gold piping.
