Stamping elbow, the price of stamping elbow, elbow factory supply 13323070761 stamping elbow detail stamping elbow molding process is complex, depending on the material and uses welding pressure gradually forming. Forming stamping elbow need to follow certain processes, strict compliance with the corresponding process, or production of carbon steel stamping the elbow will produce quality problems. Large stamping elbow forming the basic process is: First welding a cross-section for the polygon Duoleng ring shell or closed at both ends Duoleng fan-shaped shell, when the internal pressure washed over medium less applied pressure, including pressure role under the cross-section polygon gradually turns round, and eventually becomes a circular ring shells. Stamping elbow standard: stamping elbow is now internationally accepted standards is the national standard ANSIB16.9 in the United States and 16.28. The standard diameter size range of 1/2 "to 80", generally less than 24 〃 are seamless steel tubes for raw materials, 26 "to 80" are steel stamping later welding. The wall thickness of up to 60mm, and the minimum to 1. 24mm. Kinds of steel with carbon steel (20 #), alloy steel and stainless steel, a total of 24 kinds of steel. Boiler with CrMo steel like 15Cr, the relatively large amount. Tee, outside diameter range of 2.5 "-60", 26 "-60" welded tees. Wall thickness of 28-60mm. The size of the first specification range, conventional first say that the bulk of specifications, say small head specifications, the bulk of minimum 0.75 〃 head minimum 0.5 ", the bulk of the largest 60 〃, a small head 48 〃 ,20-60 〃 welding, wall thickness 2.8 -4.5mm. Alloy stamping elbow stamping die stamping plates of the same material of the pipe into half a ring elbow, then the group of welding forming two semi-ring elbow. Various types of pipe welding standards, usually is a group of semi-finished factory tack, site construction pipe welds grade welding, also known as two halves welded elbow. Stamping elbow and processing by means of conventional or special stamping equipment, power, force directly affected by the mold deformation and deformation of the plate material, to obtain a certain shape, size and performance parts production technology. Sheet metal, molds and equipment punching three elements. Punching a metal cold deformation processing method. So called cold stamping, sheet metal stamping, or stamping. It is one of the main methods of metal plastic processing (or pressure processing), also part of the material forming engineering technology.
