The results show that the interaction of multi local thinning is not only related to the distance, but also to the depth of thinning. It is pointed out that when the thinning depth is shallow, the axial local thinning distance is more than 2 times of the wall thickness, and the limit load of double local thinning is basically the same as that of single local thinning. When the thinning depth is deep and the axial local thinning distance is more than 4 times of the wall thickness, the limit load of double local thinning is basically the same as that of single local thinning, which complements the shortcomings of existing research. Die forging equipment commonly used are die forging hammer, hot die forging press, flat forging machine and friction press. Generally speaking, the quality of forged flange is better. Generally, it is produced by die forging, with fine crystal structure, high strength and high price. when the input heat is insufficient, the edge of the heated welding gap exceeds the welding temperature, resulting in overburning or droplet, resulting in a weld gap with a hole. After the two edges of the wear-resistant tube blank are heated to the welding temperature, under the extrusion of the extrusion roller, the common metal grains permeate and crystallize each other, and finally a solid welding gap is produced. If the extrusion pressure is too small, the number of common crystals will be small. The strength of weld gap metal is reduced. In addition, cracks will be produced after stress, if the extrusion pressure is too large. The welding temperature can also be achieved by adjusting the welding efficiency. When the heat input is insufficient, the molten metal will be extruded out of the welding gap, not only reducing the strength of the welding gap, but alsoThere will be a large number of internal and external burrs, and even defects such as weld overlap. Connect the ends to draw the cutting line. Wall thickness treatment method: when setting out, first draw the theoretical cutting line, then determine the height according to the wall thickness, the position of the cutting line at the low point (after beveling), connect the two points, then calculate the length of the prime line at each bisection point, and then draw and cut on the coil pipe.
