Embodiment Construction

[0028] The following examples refer to Figure 1-8 .

[0029] This embodiment is a mold for trimming a titanium alloy straight pipe with a length of 200mm and a section of Φ60mm, including a base 1 of the trimming mold, a reinforcing rib 2, a splint 3, a mandrel 4, an outer mold 5, and a clamping block 6. Side plate 7, bolt 8. Among them, the splint 3 and the side plate 7 are 40 mm away from the two ends of the base 1, the reinforcing rib 2 is located outside the splint 3 and the side plate 7 and close to the end face of the base 1, the distance between two adjacent reinforcing ribs 2 is 30 mm, and the center plane of the base 1 Symmetrical, the splint 3, side plate 7 and rib 2 are fixed on the base 1 by welding, the clamping block 6 is located between the splint 3 and the side plate 7 and close to the side of the side plate 7, the position is adjustable, and the splint 3 Cooperate with clamping the outer mold 5, use the mandrel 4 to open the straight pipe piece into the out...

Abstract

The invention discloses a mold for seam trimming of a titanium alloy straight pipe and a method for machining seam trimming. The mold and the method are used for solving the technical problem that the quality of the seam trimming of the conventional titanium alloy straight pipe is difficult to guarantee. According to the technical scheme, the mold is characterized in that a clamping plate (3) and a side plate (7) are fixedly connected on a base (1), the side plate (7), a bolt (8) and the clamping plate (3) are matched with a clamping block (6) and are used for clamping an outer mold (5), a core rod (4) is arranged in the center of the outer mold (5), a trapezoid-shaped slot through which a milling cuter passes, is formed in the core rod (4), and the titanium alloy straight pipe (9) to be machined is placed between the outer mold (5) and the core rod (4); and the core rod (4) is used for propping the molded titanium alloy straight pipe open, after the titanium alloy straight pipe (9) is subjected to seam trimming, the bolt (8) is loosened, the clamping block (6) is moved away, the core rod (4) is taken out, as the diameter of the titanium alloy straight pipe is less than that of the core rod, after the titanium alloy straight pipe rebounds, seams are exactly aligned, the orderly seams are beneficial to welding, so that the quality of the seam trimming of the conventional titanium alloy straight pipes can be ensured.

Description

technical field [0001] The invention relates to a seam trimming die, in particular to a die for seam trimming of titanium alloy straight pipes. It also relates to a method for processing seam trimming by using the mold. Background technique [0002] With the continuous development of my country's aviation industry, the use of titanium alloy sheets in aircraft manufacturing is increasing. Usually, in the processing of aircraft parts, there are a large number of oil and gas pipeline parts, especially in large aircraft. The diameter of the road is getting bigger and bigger. Therefore, the manufacture of large-diameter pipelines is generally formed by cold bending of sheets, then trimming the seams of the formed straight pipes, and finally obtaining titanium alloy pipe fittings by welding the seams. This method for processing large-diameter pipe fittings has the advantages of simple process, high material utilization rate and low cost. [0003] In this processing method, the p...
