[0034] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. Example

[0035] like Figure 1 As shown, the bending forming equipment includes a bending forming support seat 1, a bending forming lower mold and a bending forming upper mold; the bending forming lower mold is arranged on the bending forming support seat 1; the bending forming lower mold includes two lower forming pins 2 and a lower pressing plate 3; the two lower forming pins 2 are vertically arranged on the bending forming support seat 1, and the spacing between the two lower forming pins 2 is adapted to the titanium alloy material to be bent; the upper shape of the inner wall of the two lower forming pins 2 is adapted to the frame shape bent into by the titanium alloy material; the lower pressing plate 3 is arranged on the bending forming On the support seat 1, and located between the two lower forming males 2; the outer walls of the two ends of the lower pressing plate 3 are fitted with the inner walls of the two lower forming males 2; the bending forming upper mold is arranged on the moving end of the external vertical lifting device, and is located directly above the bending forming lower mold; the bending forming upper mold includes a bending forming upper mold base 4 and an upper forming male 5; the upper forming male 5 is arranged on the lower surface of the bending forming upper mold base 4, and is adapted to the two lower forming males 2; the shapes of the two ends of the lower surface of the upper forming male 5 are adapted to the shape of the frame bent into by the titanium alloy material.

[0036] like Figure 2 As shown, the operation method of the titanium alloy material in step A2 in the bending forming equipment is as follows:

[0037] A2.1 Place the titanium alloy after “S”-shaped extension and forming on the lower pressing plate 3;

[0038] A2.2 Start the external vertical lifting device to make the upper forming pin 5 move vertically downward and cooperate with the two lower forming pins 2 to complete the bending forming of the titanium alloy material.

[0039] In this embodiment, a plurality of nitrogen springs 6 are provided on the bending forming support seat 1 between the two lower forming pins 2. The movable ends of the plurality of nitrogen springs 6 are vertically arranged upward and connected to the lower surface of the lower pressing plate 3, so that the lower pressing plate has a certain buffering function to prevent the upper forming pin 5 from crushing the titanium alloy material.

[0040] In this embodiment, lower outer limit columns 7 are vertically provided at both ends of the upper surface of the bending and forming support seat 1; upper outer limit columns 8 are vertically provided downwardly at both ends of the lower surface of the bending and forming upper die seat 4; the upper outer limit columns 8 correspond to the lower outer limit columns 7 one by one; the upper outer limit columns 8 and the corresponding lower outer limit columns 7 share the same axis; with this arrangement, the lower mold part is limited to avoid crushing the titanium alloy material after "S"-shaped extension forming.

[0041] Further, a pad 9 is provided on the lower surface of the bending forming upper die seat 4, and the upper forming male 5 is fixed on the pad 9; upper inner limit columns 10 are vertically provided at both ends of the pad 9; lower inner limit columns 11 are vertically provided on the inner sides of the two lower outer limit columns 7 on the bending forming support seat 1; the lower inner limit columns 11 correspond to the upper inner limit columns 10 one by one; the lower inner limit columns 11 and the corresponding upper inner limit columns 10 share the same axis; the stroke of the upper forming male 5 is limited to prevent the upper forming male 5 from crushing the titanium alloy material 12 after "S"-shaped extension forming. Further, the upper surface of the lower inner limit column 11 and the lower surface of the upper inner limit column 10 are both provided with an elastic layer to avoid rigid contact. Further, the material of the elastic layer can be rubber, silicone, polyurethane, etc.

[0042] Bending forming, due to the mechanical properties of titanium alloy mechanics and microstructure: yield strength, tensile strength, elongation, plastic strain, etc., are much worse than ordinary metal materials under the same conditions. By using this new forming structure, without changing the thickness of the forming material, after repeated verification, the problems of concave bending features, lack of material, and incompleteness have been solved. After multiple verifications of post-process CNC precision machining, the quality yield has reached the set target. This new forming structure has achieved our goal of improving efficiency and reducing costs.
