specific Embodiment approach

[0019] Referring to the accompanying drawings, the specific implementation is as follows:

[0020] A method for forming a semicircular tube plate forging that can improve the utilization rate of blanks. The semicircular tube plate forging is a flat plate of equal thickness. The two parallel sides of the flat plate of equal thickness are semicircular sides with the same size and arranged symmetrically. Equal-length trapezoid-cuboid composite blanks, such as Figure 4 As shown, the isosceles trapezoid-rectangular composite blank is composed of two isosceles trapezoids and a rectangle with the same length, the width of the small end of the isosceles trapezoid is equal to the thickness of the semicircular tube plate forging, and the The width of the large end is equal to the width of the rectangular body, and the plane of the large end of the isosceles trapezoid is aligned with the equal width plane on the corresponding side of the rectangular body, so that the two ends of the iso...

Abstract

The invention relates to a semi-circular tube plate forged piece forming method capable of improving the utilization rate of a blank. Firstly, an equal-length trapezoid body - rectangular composite blank composed of a trapezoid body and a rectangular body which are the same in length is forged; and then extruding is carried out from the two sides in the width direction of the equal-length trapezoid body - rectangular composite blank, drawing is carried out in the length direction of the equal-length trapezoid body - rectangular composite blank so as to enable the equal-length trapezoid body -rectangular composite blank to be deformed into an equal-thickness trapezoidal plate and rectangular plate composite flat plate, and the equal-thickness trapezoidal plate and rectangular plate composite flat plate is cut into an arc surface of a semi-circular tube plate forged piece so as to obtain the semi-circular tube plate forged piece. Compared with the prior art that a purely rectangular section is adopted to wrap a semi-circular section, the manner that an isosceles trapezoid and rectangular composite section is adopted to wrap a semi-circular section can reduce excess materials left after cutting, so that the size of an original blank is reduced, the blank can be saved, the utilization rate of the blank is improved, the production cost is reduced, and popularization and applicationare facilitated.

Description

technical field [0001] The invention relates to the technical field of forming metal forgings, in particular to a method for forming semicircular tube plate forgings that can improve the utilization rate of blanks. Background technique [0002] The semi-circular tube plate is a widely used forging, which is a flat plate with a semicircular cross-section. The existing forming method of the semi-circular tube plate forging is to first forge a rectangular equal-thickness plate, and the rectangular equal-thickness plate The length is the diameter of the semi-circular tube plate forging, the width of the rectangular equal-thickness plate is the radius of the semi-circular tube plate forging, the thickness of the rectangular equal-thickness plate is equal to the thickness of the semi-circular tube plate forging, and then the rectangular equal-thickness plate is cut to get Semicircular tube sheet forgings. The essence of this molding method is to use a rectangular section to envel...
