[0005] Base;
[0006] a first semi-cylindrical rod, one end of which is horizontally fixed on the base;
[0007] A second semi-cylindrical rod, wherein the second semi-cylindrical rod cooperates with the first semi-cylindrical rod to form a cylindrical rod structure, and an outer wall of the second semi-cylindrical rod is provided with a groove for forming a boss.
[0008] According to some other embodiments of the present invention, in the pressing tool for the boss in the cylindrical shell, a travel groove is provided on the first semi-cylindrical rod, and a travel bump is provided on the second semi-cylindrical rod, and the travel groove cooperates with the travel bump.
[0009] According to the pressing tooling of the boss in the cylindrical shell in other embodiments of the utility model, the travel groove extends along the length direction of the first semi-cylindrical rod, and the travel protrusion extends along the length direction of the second semi-cylindrical rod.

[0012] According to the pressing tool for the boss inside the cylindrical shell of some other embodiments of the utility model, the length of the second semi-cylindrical rod is smaller than the length of the first semi-cylindrical rod.
[0013] The pressing tooling for the boss in the cylindrical shell of the utility model embodiment has at least the following beneficial effects: during use, the cylindrical shell to be pressed is fixed, and then the first semi-cylindrical rod and the second semi-cylindrical rod are assembled and inserted into the cylindrical shell, and then the tooling is fixed, and then the round shell is punched. After the cylindrical shell is pressed, a boss structure will be formed through the groove on the second semi-cylindrical rod. After the boss structure is formed, the base is released, and the base together with the first semi-cylindrical rod is pulled out of the cylindrical shell. At this time, the second semi-cylindrical rod can be taken out of the round shell by knocking on the second semi-cylindrical rod.

[0022] During use, the cylindrical shell to be pressed is fixed, and then the first semi-cylindrical rod 2 and the second semi-cylindrical rod 3 are assembled and inserted into the cylindrical shell, and then the tooling is fixed, and then the round shell is punched. After the cylindrical shell is compressed, a boss structure will be formed through the groove 30 on the second semi-cylindrical rod 3. After the boss structure is formed, the base 1 is released, and the base 1 together with the first semi-cylindrical rod 2 are pulled out of the cylindrical shell. At this time, the second semi-cylindrical rod 3 can be taken out of the round shell by knocking on the second semi-cylindrical rod 3. This tooling can quickly form a boss structure in the cylindrical shell. Compared with the traditional post-installation production method, the use of this tooling to form the boss is less difficult, which speeds up the production efficiency and also reduces the production cost of the cylindrical shell.
[0023] In addition, the first semi-cylindrical rod 2 and the second semi-cylindrical rod 3 in the present application are both connected in a matching manner. After the impact of the cylindrical shell is completed, the first semi-cylindrical rod 2 is pulled out first and then the second semi-cylindrical rod 3 is taken out.
