Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, and particularly relates to a metal additive pipe. Background Art

[0002] Metal additive manufacturing is an advanced manufacturing technology, also known as 3D printing metal. It involves the process of adding metal materials layer by layer to the object to be built, rather than forming an object by the traditional method of removing materials. This method allows the manufacture of complex shapes and structures, as well as highly personalized components, while reducing material waste. Among them, the metal additive pipe is a pipe made by thickening a base material layer by layer using additive manufacturing.

[0003] The conventional metal additive pipes do not have a structure that can conveniently improve the adhesion of the additive, and the additive is prone to detachment from the base material. Summary of the Invention

[0004] In view of the problems in the prior art, the utility model provides a metal additive pipe, which has a structure that can conveniently improve the adhesion of the additive, and the additive is not easy to detach from the base material.

[0005] The technical solution adopted by the utility model to solve its technical problems is a metal additive pipe, which includes an additive layer, a base material layer and a connecting flange. Connecting flanges are arranged at both ends of the additive layer, and the base material layer is located inside the additive layer;

[0006] An annular block is arranged on the periphery of the base material layer near the inner side of the connecting flange. A convex edge is arranged at the inner side of the top end of the annular block, and an attachment groove is formed on the convex edge. Vertical grooves and horizontal grooves perpendicular to each other are formed on the outer wall of the additive layer.

[0007] By adopting the above technical solution, through the vertical grooves and horizontal grooves, the additive layer can have a good adhesion effect after spraying. Then, through the shielding effect of the annular block and the attachment groove, the adhesion effect of the additive layer can be further improved, so that the additive pipe of the utility model has a structure that can conveniently improve the adhesion of the additive, and the additive is not easy to detach from the base material.

[0008] Specifically, a reinforcing plate is arranged between the annular block and the connecting flange, and reinforcing ribs are arranged at the connecting corners of the reinforcing plate with the annular block and the connecting flange.

[0009] Specifically, mounting holes are formed through the connecting flange.

[0010] By adopting the above technical solution, it is convenient to connect the connecting flange with the flange of the external pipe by passing an external bolt through the mounting hole.

[0011] Specifically, a chamfer is arranged at the inner edge of the convex edge.

[0012] By adopting the above technical solution and by means of the oblique chamfer, the spraying material of the additive layer can better enter the inner side of the annular stopper during spraying.

[0013] Specifically, the additive layer is made by spraying ceramic material.

[0014] Specifically, the substrate layer is made of POM material.

[0015] Beneficial effects of the utility model:

[0016] The metal additive tube described in the utility model can make the additive layer have good adhesion effect after spraying through the longitudinal grooves and the transverse grooves. The shielding effect of the annular block and the adhesion groove can further improve the adhesion effect of the additive layer, so that the additive tube has a structure that can easily improve the adhesion of the additive, and the additive is easy to separate from the substrate.
