DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Example 1

[0028] Reference Figure 1 , 90° titanium alloy pipe bending stamping die, which is used in the field of titanium alloy pipe bending production equipment, includes: a support, a die, multiple ejector rods and connecting components and other parts.

[0029] The support includes a base 1 and a top cover 3 located above the base 1. A pressure plate 5 is slidably arranged between the base 1 and the top cover 3. The pressure plate 5 is used to provide stable pressure during the stamping process to ensure the forming quality of the titanium alloy elbow.

[0030] The die part includes a die base 8 and a pressing head 6. The die base 8 is fixedly arranged on the top of the base 1, and the pressing head 6 is fixedly arranged on the bottom of the pressing plate 5. The pressing head 6 cooperates with the die base 8 to complete the stamping forming of the titanium alloy elbow.

[0031] Reference Figure 5 A plurality of ejector pins 24 are arranged inside the inner cavity 23 for demoulding. The top ends of the ejector pins 24 slide through the outside of the mold base 8 to facilitate ejecting the formed titanium alloy elbow during the demoulding process.

[0032] Reference Figure 2-4The connecting assembly is used to drive multiple ejector rods 24 to perform demoulding operations. The assembly includes a slide plate 2, a vertical plate 9 and a baffle plate 11. The vertical plate 9 is fixedly arranged at the bottom of the top cover 3, and the slide plate 2 is slidably arranged inside the vertical plate 9. A groove 18 is opened at one end of the baffle plate 11 close to the side of the slide plate 2. A rotating rod 19 is fixedly arranged inside the groove 18. One end of the rotating rod 19 is rotatably arranged on one side of the slide plate 2. The outer wall of the rotating rod 19 is sleeved with a torsion spring 17. The two ends of the torsion spring 17 are respectively fixedly arranged on one inner wall of the groove 18 and one side of the slide plate 2. This structure enables the slide plate 2 to slide when subjected to external force, and to return to its original position by the elastic force of the torsion spring 17 after the external force disappears.

[0033] A plug rod 15 is fixedly provided on the side of the baffle 11 close to the skateboard 2, a semi-arc hole 16 is provided on one side of the skateboard 2, a lower semi-arc groove 13 and a vertical groove 14 are provided on the side of the vertical plate 9 close to the skateboard 2, and the bottom end of the vertical groove 14 is connected to the top end of the lower semi-arc groove 13, and an upper semi-arc groove 12 is also provided on one side of the vertical plate 9, and the bottom end of the upper semi-arc groove 12 is connected to the top end of the vertical groove 14. This structure can control the movement of the skateboard 2 by limiting the movement trajectory of the plug rod 15.

[0034] A support rod 10 is fixedly provided at the bottom of the pressing plate 5 , and the support rod 10 cooperates with the baffle 11 . When the pressing plate 5 moves downward, the support rod 10 pushes the baffle 11 to slide downward, thereby driving the slide plate 2 to slide inside the vertical plate 9 .

[0035] Specifically, when the pressure plate 5 drives the support rod 10 to move downward, when the support rod 10 touches the baffle plate 11, the insertion rod 15 at one end of the baffle plate 11 extends through the semi-arc hole 16 to the inside of the lower semi-arc groove 13, so that the baffle plate 11 can be smoothly rotated through the rotating rod 19, thereby ensuring that the support rod 10 can move downward normally and the baffle plate 11 is reset. Then, when the pressure plate 5 moves upward, the support rod 10 touches the baffle plate 11, due to the vertical groove 14 between the lower semi-arc groove 13 and the upper semi-arc groove 12, the baffle plate 11 cannot continue to rotate, and can only drive the baffle plate 11 and the slide plate 2 to move upward, and the insertion rod 15 will enter the inside of the vertical groove 14. Then, when the support rod 10 continues to move upward, it will drive the insertion rod 15 to enter the inside of the upper semi-arc groove 12. At this time, the baffle plate 11 will rotate along the upper semi-arc groove 12, allowing the support rod 10 to continue to move upward, and the baffle plate 11 will be reset by the torsion spring 17, and the slide plate 2 will fall accordingly.

[0036] Reference Figure 5The connecting component also includes a connecting plate 20. A sliding hole 21 is opened on one side of the mold base 8 close to the skateboard 2. The connecting plate 20 is slidably arranged inside the sliding hole 21. A bottom plate 22 is slidably arranged inside the inner cavity 23. A plurality of ejector rods 24 are fixedly arranged on the top of the bottom plate 22. One end of the connecting plate 20 close to the bottom plate 22 is set as a No. 1 inclined surface, which cooperates with the bottom plate 22. A cross plate 7 is fixedly arranged on one side of the skateboard 2 close to the connecting plate 20. One end of the connecting plate 20 close to the cross plate 7 is set as a No. 2 inclined surface, which cooperates with the cross plate 7. When the cross plate 7 moves upward, the cross plate 7 will push the connecting plate 20 to move horizontally through the No. 2 inclined surface. The connecting plate 20 pushes the bottom plate 22 upward through the No. 1 inclined surface, and the bottom plate 22 finally pushes out the stamped bent pipe through the ejector rod 24 to achieve the demoulding effect.

[0037] Specifically, when the pressing plate 5 drives the pressure head 6 downward for stamping, it can move downward normally. When the stamping is completed and the pressing plate 5 returns to its original position, it will drive the slide plate 2 to move upward through the connecting assembly. The slide plate 2 moves through the cross plate 7, so that the push rod 24 pushes out the bent plate after stamping to achieve the demolding effect.

[0040] However, as is well known to those skilled in the art, the working principle and wiring method of the hydraulic cylinder 4 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any selections according to their needs or convenience.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
