Background technique

Titanium alloy fasteners are the most commonly used parts in the modern aerospace field. Compared with steel products, titanium alloy fasteners have the advantages of small specific gravity, high specific strength and good corrosion resistance. At present, titanium alloy fasteners are mostly processed by turning and milling, and turning and milling not only waste raw materials, but also have low efficiency, and some special-shaped parts with a large deformation ratio of the rod and head are also difficult to use turning and milling. The method is used for processing and manufacturing, or the quality of the manufactured product is not good. For example, titanium alloy slotted nuts. In the prior art, a thick titanium alloy rod is used to turn the outer circle of the head first, then mill the hexagonal, and finally mill the slot. This is a huge waste of raw materials, high cost, low efficiency and low quality. unstable.

The technical solution adopted by the utility model is: a titanium alloy slotted nut molding die, including a lower die and an upper die that cooperate with each other, through holes are arranged on the upper and lower surfaces of the lower die, and the lower surface of the upper die and the lower die is opposite A stamping head is provided; the stamping head includes a stamping head a arranged on the lower surface of the upper die, the stamping head a is in the shape of a regular hexagonal column, the free end of the stamping head a is fixed to the stamping head c, and the stamping head c is in the shape of a circular platform with a large upper part and a smaller lower part , stamping head c is set coaxially with stamping head a, the free end of stamping head a is located on both sides of stamping head c, and two stamping heads b are fixed symmetrically, and stamping head b is strip-shaped; the orthographic projection of two stamping heads b The connecting line along the longitudinal center line is located on the diameter of the orthographic projection of the stamping head c, one end of the orthographic projection of the two stamping heads b is connected to the orthographic projection of the stamping head c, and the other end of the orthographic projection of the two stamping heads b is connected to the orthographic projection of the stamping head a The orthographic projections are connected.

The utility model is also characterized in that:

The through hole includes a first hole arranged on the lower surface of the lower die and a second hole arranged on the upper surface of the lower die; the cross section of the second hole is a regular hexagon, and the radius of the circumscribed circle of the cross section of the second hole is the same as that of the cross section of the stamping head a. The radii of the circumscribed circles are equal; a mandrel is arranged in the first hole.

The stamping head a is fixed at the center of the lower surface of the upper die, and the through hole is arranged at the center of the lower die.

Stamping head a, punching head b and punching head c are punching heads made of _M2 high-speed steel.

The beneficial effects of the utility model are: adopt the molding die of the utility model to process the titanium alloy slotted nut, through the cooperation of the lower mold and the upper mold, use the stamping head to pier the titanium alloy rough bar, so that the six sides and the steps The hole and slot are formed at one time, which ensures the concentricity of the step hole and greatly improves the work efficiency; and no debris is generated during the processing, which effectively saves raw materials.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

The utility model is a titanium alloy slotted nut molding die, as shown in Figure 1, comprising a lower die 1 and an upper die 2 that cooperate with each other, a through hole is provided at the center of the upper and lower surfaces of the lower die 1, and the upper die 2 and the upper die 2 are connected to each other. The opposite lower surface of the lower die 1 is fixed with a punching head; the punching head includes a punching head a5 fixed at the center of the lower surface of the upper die 2, the punching head a5 is in the shape of a regular hexagonal column, and the free end of the punching head a5 is fixed to the punching head c7, the stamping head c7 is in the shape of a circular platform with a large upper part and a smaller lower part. The stamping head c7 and the stamping head a5 are coaxially arranged. The free end of the stamping head a5 is located on both sides of the stamping head c7 and is symmetrically fixed to two stamping heads b6 and the stamping head b6. It is elongated, and the stamping head a5, the two stamping heads b6 and the stamping head c7 are fixed as a whole; the line connecting the orthographic projections of the two stamping heads b6 along the long center line is located on the diameter of the orthographic projection of the stamping head c7, One end of the orthographic projection of the two stamping heads b6 is connected to the orthographic projection of the stamping head c7, and the other end of the orthographic projection of the two stamping heads b6 is connected to the orthographic projection of the stamping head a5.
