[0035] The inner component 1 is located inside the outer component 2 and is fixed by bolts;

[0036] The outer layer component 2 is a T-shaped truncated cone, which includes a large diameter section 2.1 at one end and a small diameter section 2.2 at the other end. The large diameter section 2.1 and the small diameter section 2.2 of the truncated cone are hollow and connected.

[0037] The direction of the large diameter section 2.1 is the inlet end of the metal glue, and the direction of the small diameter section 2.2 is the outlet end of the metal glue;

[0038] An extension platform 2.3 is formed along the circumferential direction on the inner diameter of the large diameter section 2.1 from the inlet end of the metal glue to the outlet end of the metal glue. The extension platform 2.3 is used to receive the inner layer component. A set of bolt holes A2.4 are opened at any position on the end surface of the large diameter section 2.1, close to the outer diameter of the small diameter section 2.2, at the other end of the large diameter section 2.1. The heads of the bolt holes A2.4 extend through the extension platform 2.3.

[0039] In this embodiment, the inner diameter of the extension platform 2.3 is Ø55, the outer diameter of the extension platform 2.3 is Ø68, and the depth of the extension platform 2.3 is h=8mm;

[0040] The number of bolt holes A2.4 on the end face of the large-diameter section 2.1 is two, and the positions of the two bolt holes A2.4 are located in any horizontal 180° direction on the end face of the large-diameter section 2.1;

[0041] In this embodiment, the large end diameter of each bolt hole A2.4 is 8.8 mm, and the small end diameter is 5 mm;

[0042] The cavity inside the small-diameter section 2.2 is designed in a tapered shape and gradually shrinks from the direction of the rubber inlet to the direction of the rubber outlet;

[0043] In this embodiment, the inner diameter of the tapered cavity 2.5 is 25±0.05.

[0044] The inner layer assembly 1 of the present scheme is a "gyroscope" type integral piece, which includes a conical head at one end, a center shaft 1.1 with a flat end, and a disc 1.2 located in the conical direction of the center shaft 1.1. The disc 1.2 is a hollow structure and is connected between the disc 1.2 and the center shaft 1.1 through a connecting rib 1.3, which is horizontally supported on the inner diameter of the disc 1.2 to divide the cavity of the disc 1.2 into two halves, forming a "halving". The disc 1.2 edge has bolt holes B1.4 corresponding to the bolt holes 2.4 of the large-diameter section 2.1 of the outer layer assembly 2, which are matched with the bolt holes A2.4 and the bolt holes B1.4, used for the fixed connection between the inner layer assembly 1 and the outer layer assembly 2;

When the extrusion die 8 is used, the rubber enters from the inlet end of the die 8, passes through the rubber passage 3 to the outlet end of the die 8, that is, is extruded from the position of the outer diameter of the flat end of the center shaft 1.1 of the inner layer assembly 1 and the tapered cavity 2.5 of the small-diameter section 2.2 of the outer layer assembly 2, thereby extruding the rubber hose of the present application.
