[0029] Operating procedures

[0030] 1. Mold closing: The first cylinder 7 pushes the upper mold 8 downward, closing with the lower mold 3 to form a cavity;

[0031] 2. Pipe forming: The heated pipe blank is placed into the cavity and pressure is applied to form the pipe.

[0032] 3. Mold opening: The return stroke of the first cylinder 7 drives the upper mold 8 to move upward;

[0033] 4. Lower mold tilting: The second cylinder 17 pushes the moving plate 18 to move down, and the lifting rod 20 causes the bearing block 21 to descend, which in turn causes the lower mold 3 to tilt around the first rotating shaft 14;

[0034] 5. Assisted demolding: The third cylinder 24 pushes the striking block 25 to gently tap the pipe to assist in demolding;

[0035] 6. Remove the tube: Easily remove the formed tube from the inclined lower mold 3;

[0038] Beneficial effects

[0039] This novel seamless shaped tube processing and forming device effectively solves the technical problem of difficult demolding in traditional devices through an innovative mold tilting mechanism and intelligent design. The rigid frame structure of the support plate 1 and the top plate 5 provides a stable working foundation for the mold. The sliding rod 9 in the groove 2 cooperates with the moving block 10 to ensure the linearity of the tilting movement of the lower mold 3. The hinge design of the first connecting block 11 and the second connecting block 12 through the first rotating shaft 14 realizes the precise angle adjustment of the lower mold 3. With the second rotating shaft 23 connecting the third connecting block 13 and the fourth connecting block 22, a dual-axis linkage mechanism is formed, which enables the lower mold 3 to tilt smoothly to the optimal demolding angle. The drive component adopts the structure of the second cylinder 17 synchronously controlling the two lifting blocks 19 through the moving plate 18, which ensures the consistency of the tilting on both sides of the mold and avoids the twisting and deformation of the tube. The third cylinder 24 on both sides of the support base 16 drives the striking block 25 to provide controllable auxiliary demolding force, solving the demolding problem of high viscosity materials. The precise fit between the guide rod 26 of the upper mold 8 and the top plate 5 ensures mold closing accuracy, the limit block 29 restricts excessive displacement of the lower mold 3, and the pad block 28 on the bottom surface of the support plate 1 effectively isolates ground vibration. The innovation of this device lies in improving the traditional vertical opening and closing mold into a tiltable structure. Precise control of the demolding angle is achieved through mechanical linkage, significantly reducing demolding resistance. The intelligent assisted demolding system replaces traditional manual hammering, improving efficiency and protecting the mold surface. The modular design allows the device to quickly adapt to the changing needs of molds of different specifications, meeting the requirements of multi-variety production.

[0040] These design features give the device a significant advantage in the field of irregular tube processing, not only improving forming quality and production efficiency, but also extending the service life of molds, providing reliable technical equipment for high-precision irregular tube manufacturing.
