Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile processing, in particular to a processing die for high-hard aluminum profiles. Background Technique

[0002] With the rapid development of science and technology, the composition of modern automotive manufacturing materials has changed significantly. The scope of use of non-ferrous light metals is constantly expanding. Especially for light alloy materials, aluminum alloys are widely used in various links of industrial production and the automotive and aerospace fields due to their light weight, beauty, good thermal conductivity, and easy processing into complex shapes. The aluminum profile material 9003 belongs to high-hard aluminum. When extruded, the surface of this aluminum profile is very rough, seriously affecting the surface quality of the product and resulting in very low production efficiency. Summary of the Invention

[0003] The utility model provides a processing die for high-hard aluminum profiles, which can improve the problem of rough surfaces of products produced from high-hard aluminum alloy materials to solve the technical problems mentioned in the background technique.

[0004] The technical solution of the utility model is as follows:

[0005] A processing die for high-hard aluminum profiles includes: a die body. A feeding cavity is provided at the center of the die body. The side wall of the feeding cavity is divided into a first feeding section and a second feeding section. The first feeding section is inclined, and the tail end of the first feeding section is connected to the head end of the second feeding section. The second feeding section is vertically arranged. A working belt forming cavity is provided at the center of the feeding cavity. The feeding cavity is located above the working belt forming cavity. The side wall of the working belt forming cavity is divided into a first forming section and a second forming section. The first forming section is inclined, and the tail end of the first forming section is connected to the head end of the second forming section. The second forming section is vertically arranged. A discharging cavity is provided at the bottom of the working belt forming cavity.

[0006] Further, the four corners of the feeding cavity are arc-shaped.

[0007] Further, the length and width of the feeding cavity are greater than those of the working belt forming cavity, and the length and width of the discharging cavity are greater than those of the working belt forming cavity and less than those of the feeding cavity.

[0008] Further, the inclination angle of the first feeding section is greater than that of the first forming section.

[0009] Further, the height in the width direction of the working belt forming cavity is equal to the height in the length direction.

[0010] Advantages of the present utility model: Due to the right angle formed by the second feeding section and the bottom of the feeding cavity in the present utility model, some particulate matters in the aluminum rod are left in this right angle when the high-hard aluminum alloy material flows through the bottom. Through the slope transition of the first forming section again, the friction of the high-hard aluminum alloy material is increased, and the slower precipitation of the particulate matters in the high-hard aluminum alloy material is caused by the increased friction. The present utility model can improve the problem of rough surface of the products produced from high-hard aluminum alloy materials. Description of the Drawings

[0013] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. The described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0014] In the embodiments of the present utility model, Figure 1 and Figure 2 are structural schematic diagrams provided according to the specific structure of a high-hard aluminum profile processing die of the present utility model. As Figure 1 and Figure 2 shown, the present utility model includes:

[0015] A die body, a feeding cavity 1 is provided at the center of the die body, the side wall of the feeding cavity 1 is divided into a first feeding section 3 and a second feeding section 4, the first feeding section 3 is inclined, the tail end of the first feeding section 3 is connected to the head end of the second feeding section 4, the second feeding section 4 is vertically arranged, so that a 90° angle is formed between the second feeding section 4 and the bottom of the feeding cavity 1.

[0016] A working belt forming cavity 2 is provided at the center of the feeding cavity 1, the feeding cavity 1 is located above the working belt forming cavity 2, the side wall of the working belt forming cavity 2 is divided into a first forming section 5 and a second forming section 6, the first forming section 5 is inclined, the tail end of the first forming section 5 is connected to the head end of the second forming section 6, the second forming section 6 is vertically arranged, and a discharging cavity 7 is provided at the bottom of the working belt forming cavity 2.

[0017] In an embodiment of the present utility model, the four corners of the feeding cavity 1 are arc-shaped.

[0018] In an embodiment of the present utility model, the length and width of the feeding cavity 1 are greater than those of the working belt forming cavity 2, and the length and width of the discharging cavity 7 are greater than those of the working belt forming cavity 2 and less than those of the feeding cavity 1.

[0019] In an embodiment of the present utility model, the inclination angle of the first feeding section 3 is greater than that of the first forming section 5.

[0020] In an embodiment of the present utility model, the height in the width direction of the working belt forming cavity 2 is equal to the height in the length direction.

[0021] The principle of the present utility model is as follows: The aluminum profile processed by the present utility model is 9003, which belongs to high-hard aluminum. After extruding 3-section billets during normal production, the surface of the profile becomes rough and production cannot continue, resulting in a significant reduction in production efficiency. To improve the surface quality and production efficiency of the product, the area of the feeding cavity 1 is smaller than the cross-sectional area of the product to be produced. The feeding cavity 1 is appropriately reduced according to the shape of the product to be produced. At the same time, small slopes are used for the transition around the feeding cavity 1, that is, the first feeding section 3 is inclined. When transitioning to the bottom of the feeding cavity 1, a right angle is adopted, that is, the second feeding section 4 is vertically arranged to form a right angle with the bottom of the feeding cavity 1, so that some particulate matters in the aluminum rod are left in this dead corner when the high-hard aluminum alloy material flows through the bottom. When the high-hard aluminum alloy material is still flowing through the working belt forming, a slope is used again for the transition to the working belt forming part, that is, the first forming section 5. The slope of the first forming section 5 is 5 degrees. Through the slope transition again, the friction of the high-hard aluminum alloy material is increased, and the increase in friction makes the particulate matters in the high-hard aluminum alloy material sucked out slowly. The height of the forming working belt is all the same, that is, the second forming section 6, which can ensure the stable size of the profile. The clearance for the blanking at the rear is increased, that is, the discharging cavity 7, so that the particulate matter accumulation in the high-hard aluminum alloy material is reduced or a small part is carried away at the clearance.

[0022] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the examples, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
