Description

Technical Field

[0001] The utility model relates to the technical field of titanium alloy profiles, in particular to a multi-purpose titanium alloy profile extrusion die. Background Art

[0002] Titanium alloys have good mechanical properties and corrosion resistance and are widely used in the aerospace field. Since titanium alloy materials are difficult to machine, titanium alloy products are usually manufactured by casting or extrusion, such as producing titanium alloy profiles through extrusion.

[0003] In practical applications, titanium alloy profiles are mostly T-shaped and I-shaped profiles (T profiles and H profiles), and the same type of T profiles have different size specifications, which requires the design and manufacture of a large number of extrusion dies to meet production needs. It is precisely because of this that the manufacturing cost of the mold has been greatly increased. Utility Model Content

[0004] In order to overcome the shortcomings of the background technology, the utility model discloses a multi-purpose titanium alloy profile extrusion die, which adopts the following technical solutions:

[0005] A multi-purpose titanium alloy profile extrusion die has an I-shaped extrusion port consisting of two transverse long grooves and one vertical long groove, a sink is provided in the middle of the I-shaped extrusion port, and a mold changing module is detachably connected inside the sink; the mold changing module has an insert matching the width of the vertical long groove, and the insert is used to divide the I-shaped extrusion port into two T-shaped extrusion ports.

[0006] To further improve the technical solution, the sinking platform is a rectangular sinking platform, and the main body of the mold changing module is adapted to the rectangular sinking platform.

[0007] To further improve the technical solution, two threaded holes are provided on the sinking platform, countersunk bolt holes corresponding to the threaded holes are provided on the mold changing module, and the mold changing module is detachably connected to the sinking platform by bolts.

[0008] To further improve the technical solution, the width of the insert is smaller than the width of the main body of the conversion module.

[0009] To further improve the technical solution, the width of the insert is equal to or greater than the width of the main body of the conversion module.

[0010] To further improve the technical solution, the extrusion die also includes a replaceable insert matched with the sinker, and the replaceable insert is used to fill the sinker.

[0011] After implementing the above technical solution, compared with the background technology, the beneficial effects produced by the utility model are:

[0012] The extrusion die has a sink and a mold changing module. By replacing the mold changing module, not only T-profiles of different sizes and specifications can be produced, but also I-shaped profiles can be produced.

[0013] The extrusion die has multiple uses, which greatly reduces the manufacturing cost of the die. BRIEF DESCRIPTION OF THE DRAWINGS

It should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or the internal connection of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. Embodiment 1:

[0023] A multi-purpose titanium alloy profile extrusion die is used for extruding T-shaped titanium alloy profiles.

[0024] See attached Figure 1 and attached Figure 2 The main body of the extrusion die 1 has an I-shaped extrusion port 11 consisting of two transverse long grooves and one vertical long groove, and a sink 12 is provided in the middle of the I-shaped extrusion port 11. In this embodiment, the sink 12 is a rectangular sink 12, and two threaded holes 13 are provided on the sink 12. The rectangular sink 12 and the I-shaped extrusion port 11 are in a W shape.

[0025] A mold change module 14 is detachably connected to the sink 12 via bolts.

[0026] See attached Figure 3 The main body of the mold-changing module 14 is a module body 141, which is a rectangular body, and its size is adapted to the rectangular sink 12. Two countersunk bolt holes 142 corresponding to the threaded holes 13 are provided on the module body 141, and the mold-changing module 14 can be detachably connected to the sink 12 by bolts. The mold-changing module 14 has an insert 143 that matches the width of the vertical long slot. In this embodiment, the width of the insert 143 is equal to the width of the main body of the mold-changing module 14.

[0027] See attached Figure 4After the mold changing module 14 is installed in the countersunk hole, the module body 141 fills the countersunk hole, the insert 143 is inserted into the vertical long groove, and the I-shaped extrusion opening 11 is divided into two T-shaped extrusion openings 16. At this time, the titanium alloy blank is extruded from the two T-shaped extrusion openings 16 to form a T-shaped cross-section. Embodiment 2:

[0028] See attached Figure 5 In this embodiment, the width of the insert 143 is smaller than the width of the main body of the conversion module 14. Such a structure can increase the height of the vertical plate of the T-profile to obtain T-profiles of different sizes. Embodiment three:

[0029] See attached Figure 6 In this embodiment, the width of the insert 143 is greater than the width of the main body of the conversion module 14. Such a structure can reduce the height of the vertical plate of the T-profile to obtain T-profiles of different sizes. Embodiment 4:

[0030] See attached Figure 7 In this embodiment, the extrusion die 1 further includes a replaceable insert 15 adapted to the sink 12. After the replaceable insert 15 is installed in the sink hole, the sink 12 can be filled to form a complete I-shaped extrusion port 11. At this time, the titanium alloy blank is extruded from the I-shaped extrusion port 11 to form a profile (H profile) with an I-shaped cross section.

[0031] As can be seen from the above embodiments, the extrusion die 1 has a sink 12 and a mold changing module 14. By replacing the mold changing module 14, not only T-shaped profiles of different sizes can be produced, but also I-shaped profiles can be produced. The extrusion die 1 has multiple uses, which greatly reduces the manufacturing cost of the die.

[0032] Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the protection scope of the present invention is defined by the attached claims and their equivalents.
