Supply stamping head, steel stamping head, punching head plant Cangzhou Main: elliptical head, spinning head, stainless steel head, pressure vessel head, butterfly head, the hat, the ball head , flat head; Hebei Lee Yip head plant perennial large supply of high-quality stamping head, quality assurance and affordable. Elliptical head for standard series of head generally use stamping, but for non-standard series of head or large diameter head, the general Spinning. Spinning with respect to the press, there are saving tooling costs, the advantages of size can be adjusted as required. Generally elliptical head spinning spinning head cold, but head thicker or material strength is high when there are difficulties with cold spinning on the edge of the cold spinning equipment capacity limit of the head, if you use cold spinning, will delamination, surface microcracks problems; exceeding the capacity of the cold spinning can not process. In this case, hot spinning processing methods. Elliptical head spinning process heat, flame spray heat, because of the need to stay out of the location of processing and heating, insulation equipment can not be fully closed, the effect is far less than the heating furnace, therefore, uneven temperature, will inevitably lead to inconsistencies organization without hemming Simplified use of spherical head and fillet welds, the middle is often used as a container receiving chamber of two separate head, but also for the end of the head. Under the same conditions required pressure the thinnest, from saving material and strength point of view, is the most reasonable. Common carbon steel head: Q235B, 10 #, 20 #, 35 #, 45 #, 16Mn, Q345B, 20G. My company has a variety of head six sets of processing equipment, various models of various materials can suppress the head, such as the oval head, conical head, dished head, flat head, the pressure vessel head, tank head, punching seal top. Manufactured head sales across the country. Techniques pressure vessel head testing: Measure the circumference of the head. If the advance barrel processed, please ask the company a predetermined outer perimeter size. Please head circumference quartiles, and mark and seal in the cylinder head.
