Also known as the radius of the hemispherical dome section known as square and round radius section price action radius of the quality assurance section

Both parties hemispherical dome shape pipe fittings of another round as the name suggests, the shape of the tube in the groin and upper body is round and square, generally applicable to the special structure components. Tianyuandefang pipe material 20, Q195, Q215A, B Q235A, B, Q345A, B, C, D, E GB / T13793-1992 GB3091-2001 Q235A-B, Q345A-E 10 # 20 # 45 # 16mn j55 k55 [1] Tianyuandifang pipe major of the production process to push the system, extrusion and other methods Tianyuandifang fittings currently no industry standard basic standards in accordance with galvanized pipe fittings Tianyuandifang partial cold galvanized and hot dip galvanized. Sandblasting is to rust, paint for corrosion protection. Yongsheng radius section is provided by the company. 0317-6856098. 2014 introduced a new upgrade section radius of the best manufacturers, radius Festival Recent Lowest Price radius section Material specification models radius radius section section section uses a radius of action radius of the Profile section from an ideal general analysis section structure characteristic radius start, An improved method for general manual lofting radius section, the method not broken "Tianyuan" the circular surface to approximate solving loft, but a direct stake out a line drawn arc; calculate the radius of the section of the general theory area calculation formulas and suggestions on how to improve the method of calculation loft area, which can quantitatively know lofting precision; hemispherical dome shape flat shape, curved shape (spherical, parabolic, etc.) and cone, several common flange Punches structural shape, figure punch punch diameter section of the working part, punch diameter section of the guide being part of the shaping step 1, 2 conical transition section, wherein: with guide pin being tapered punch When the vertical edge not very tall, vertical side diameter greater than 10, can be designed plastic stairs, on the contrary not to set shaping steps, when using the blank flange ring mold or not to set shaping step; a dual arc-shaped no Daozheng The curved pin punch, while the vertical edge with a diameter greater than 6:00 flat, vertical edge diameter less than or equal to 6:00 with round; belt Daozheng pin diameter of less than 4 vertical edges simultaneously punching and flanging punch . In addition, for non-pre-hole punch with a conical tip. Convex and concave mold size can refer to the size of the drawing die to determine the principles identified, but should be taken to ensure the flange gap. The bigger the better punch radius, preferably curved or tapered punch for punch and generally flat ≥4. Die radius of the workpiece can be sized according to the requirements, but the workpiece flange radius less than the minimum should be the shaping process.
