Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile processing, in particular to a combined aluminum profile stretching die head. Background Art

[0002] With the rapid development of the industrial field, aluminum profiles, as lightweight and high-strength metal materials, have been widely used in many fields such as aerospace, automobile manufacturing, electronic communications and construction. In the manufacturing process of aluminum profiles, stretching is a crucial link, which directly affects the quality and performance of aluminum profiles;

[0003] In the aluminum profile stretching process, the die head is a component that directly determines the shape and size of the aluminum profile, and its design is crucial. Traditional stretching die heads usually adopt an integrated design. Once the shape of the die head is determined, it is difficult to adapt to the stretching needs of aluminum profiles of different specifications and shapes. This design method not only limits the diversity of aluminum profiles, but also increases manufacturing costs and production cycles. Therefore, we proposed a combined aluminum profile stretching die head to solve the above problems. Utility Model Content

[0024] like Figure 1-Figure 5 As shown, a combined aluminum profile stretching die head proposed in an embodiment of the utility model comprises a stretching die head body 1, a shape die 2 is movably contacted on the stretching die head body 1, two L-shaped rods 3 are fixedly connected to one side of the shape die 2, a card slot 4 is provided on one side of the L-shaped rod 3, two cavities 5 are provided on the stretching die head body 1, two protective sleeves 6 are fixedly connected to the top of the stretching die head body 1, a moving rod 7 is slidably connected to the protective sleeve 6, the bottom end of the moving rod 7 extends into the corresponding cavity 5 and is rotatably connected to an obliquely arranged hinged rod 8, a fixing rod 9 is fixedly connected to the inner wall of one side of the cavity 5, a card rod 10 is slidably connected to the fixing rod 9, a first spring 11 is fixedly connected between the end of the card rod 10 and the inner wall of one side of the corresponding cavity 5, the first spring 11 is movably sleeved on the corresponding fixing rod 9, and the card rod 10 is carded with the corresponding card slot 4, One side of the clamping rod 10 is hinged to the end of the corresponding hinged rod 8. The moving rod 7 is pressed by an external object. The moving rod 7 drives the clamping rod 10 to slide on the fixed rod 9 through the hinged rod 8 and compresses the first spring 11, so that the clamping rod 10 is separated from the corresponding clamping groove 4. Then the shape mold 2 is moved, and the shape mold 2 drives the L-shaped rod 3 to separate from the stretching die body 1. The L-shaped rod 3 on the other shape mold 2 is inserted into the cavity 5. When the bottom of the shape mold 2 contacts the top of the stretching die body 1, the pressure on the moving rod 7 is placed at this time, and the first spring 11 in the compressed state is reset. The first spring 11 drives the corresponding clamping rod 10 to be clamped with the clamping groove 4, so that the shape mold 2 is fixed to the stretching die body 1 through the L-shaped rod 3, so that it is easy to replace the shape mold 2, and can adapt to the stretching needs of aluminum profiles of various specifications and shapes.

[0025] like Figure 5As shown, in some embodiments, a limiting ring 12 is fixedly connected to the moving rod 7, and a second spring 13 is fixedly connected between the top of the limiting ring 12 and the top inner wall of the corresponding cavity 5. The second spring 13 is movably mounted on the corresponding moving rod 7. The setting of the second spring 13 plays a role of automatic resetting.

[0026] like Figure 5 As shown, in some embodiments, a square hole 14 is opened on the top inner wall of the cavity 5, and the inner wall of the square hole 14 is in active contact with the outer side of the corresponding L-shaped rod 3. The setting of the L-shaped rod 3 plays a connecting role.

[0027] like Figure 5 As shown, in some embodiments, a guide hole is opened on the top inner wall of the cavity 5, and the inner wall of the guide hole is slidably connected to the outer side of the corresponding moving rod 7. The setting of the guide hole ensures that the moving rod 7 will not be affected when moving.

[0028] like Figure 5 As shown, in some embodiments, a limiting groove is provided on the clamping rod 10, and the clamping rod 10 is slidably connected with the corresponding fixing rod 9 through the limiting groove. The setting of the fixing rod 9 plays a limiting role.

[0029] According to the working principle or structural principle, when in use, the moving rod 7 is pressed by an external object, and the moving rod 7 drives the corresponding limiting ring 12 to move. The limiting ring 12 stretches the corresponding second spring 13 during the movement, and the moving rod 7 squeezes the corresponding hinged rod 8 during the movement. Under the action of the squeezing force, the hinged rod 8 moves and rotates, and the hinged rod 8 drives the corresponding clamping rod 10 to slide on the fixed rod 9. The clamping rod 10 compresses the corresponding first spring 11 during the movement, so that the clamping rod 10 is separated from the corresponding clamping slot 4, and then the shape mold 2 is moved, and the shape mold 2 is moved. 2 drives the L-shaped rod 3 to separate from the stretching die body 1, and inserts the L-shaped rod 3 on the other shape die 2 into the cavity 5 through the square hole 14. When the bottom of the shape die 2 contacts the top of the stretching die body 1, the moving rod 7 is pressed, and the first spring 11 in the compressed state is reset. Under the action of the elastic force of the first spring 11 itself, the first spring 11 drives the corresponding clamping rod 10 to be clamped with the clamping groove 4, so that the shape die 2 is fixed on the stretching die body 1 through the L-shaped rod 3, so that it is easy to replace the shape die 2, and can meet the stretching needs of aluminum profiles with different specifications and shapes.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
