Problems solved by technology
The traditional cold and hot press forming methods not only have high processing costs, but also the forming state of the inner flanging position of the part is poor, the flanging rebound is serious, and the surface of the inner flanging is prone to crushing, cracks and other processing defects that seriously affect the use of the part; and The internal flanging and rounded corners of parts formed by traditional cold and hot pressing forming methods are prone to sheet material accumulation, resulting in wrinkles; Relative friction and extrusion will also cause local sheet metal thinning or even tearing at the inner flange position of the part

Embodiment Construction
[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.
[0025] see Figure 1-4 Illustrate the present embodiment, 1. a kind of forming method of the conical titanium alloy barrel of inward flanging, it comprises the following steps:
[0026] Step 1: Connect two fan-shaped titanium alloy sheets by welding to form a titanium alloy conical cylinder 5 structure;
[0027] Step 2: Fix the spinning tooling on the vertical lathe, then fit the titanium alloy conical cylinder 5 on the outer surface of the spinning tooling expansion valve 6, and press the titanium alloy conical cylinder 5 through the pressure ring 8 and the tension screw 7. Cylinder 5 tight fit;
[0028] Step 3: Fix the spinning wheel 11 on the tool holder of the lathe, and find out the round runout and end runout of the pressing tool;
[0029] Step 4: Drive the titanium all...

The invention provides a forming method of an inward flanging conical titanium alloy barrel, belongs to the technical field of conical titanium alloy barrel forming, and particularly relates to the forming method of the inward flanging conical titanium alloy barrel. The problems that an existing traditional cold and hot pressing forming manner is high in machining cost, the forming state of the inward flanging position of a part is poor, flanging rebounding is serious, the inward flanging surface is easily crushed and cracked, and therefore use of the part is seriously affected are solved. Theforming method is mainly used for inward flanging forming of the conical titanium alloy barrel.
Description
technical field [0001] The invention belongs to the technical field of forming a conical titanium alloy cylinder, in particular to a forming method of an inwardly turned conical titanium alloy cylinder. Background technique [0002] Conical titanium alloy cylinder structural parts with inner flanging are generally used in the position of the engine inlet of drones, aircrafts, etc. service life. [0003] As a conical titanium alloy cylindrical structural part with inner flanging that is widely used in the aerospace field, the forming quality of the inner flanging of the part is very important. The traditional cold and hot press forming methods not only have high processing costs, but also the forming state of the inner flange position of the part is poor, the flange rebound is serious, and the surface of the inner flange is prone to crushing, cracks and other processing defects that seriously affect the use of the part; and The internal flanging and rounded corners of parts...
