Auxiliary tool for detecting the perpendicularity of the upper die working belt of an aluminum alloy extrusion die

Abstract

This invention provides an auxiliary tooling for detecting the perpendicularity of the working zone of the upper die of an aluminum alloy extrusion mold. The tooling includes a strip-shaped component comprising an integrally constructed base section and a support section. The thickness h4 of the support section is less than the thickness h3 of the base section, resulting in a notch above the support section relative to the base section. At this notch, the step height difference between the base section and the support section is h2. The surface above the base section is a first reference surface, and the surface below the base section and the support section is a second reference surface. The first and second reference surfaces are parallel. The step height difference h2 between the base section and the support section is greater than the height h1 of the cone on the upper die. The thickness h3 of the base section is less than the total height H of the cone and the working zone of the upper die. This invention conveniently enables the detection of the perpendicularity of the working zone of the upper die.

Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy extrusion technology, and in particular to an auxiliary tooling for detecting the verticality of the working zone of the upper die of an aluminum alloy extrusion mold. Background Technology

[0002] In the field of aluminum alloy extrusion, extrusion dies are crucial components in the aluminum alloy product manufacturing process. With the widespread application of aluminum alloys in automobiles, the requirements for the shape and size of aluminum alloy products are becoming increasingly stringent. Due to the unique nature of aluminum alloy extrusion dies—the die is continuous from front to back—the perpendicularity of the die's working zone is critical. If the working zone is not perpendicular, inconsistent aluminum alloy flow rates during extrusion will lead to problems such as incomplete product forming and dimensional defects. However, because there is a cone below the upper die's working zone, a right-angle ruler interferes with the cone, making it impossible to measure the perpendicularity of the upper die's working zone. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides an auxiliary tooling for detecting the perpendicularity of the working zone of the upper die in an aluminum alloy extrusion mold, thereby facilitating the detection of the perpendicularity of the working zone. To achieve the above technical objectives, the technical solution adopted in this utility model embodiment is as follows:

[0004] This utility model embodiment provides an auxiliary tooling for detecting the verticality of the upper die working zone of an aluminum alloy extrusion die, including a strip-shaped component, which includes an integrally constructed base section and a bearing section;

[0005] The thickness h4 of the bearing section is less than the thickness h3 of the base section, thus there is a gap above the bearing section relative to the base section; at the gap, the step height difference between the base section and the bearing section is h2;

[0006] The surface above the base segment is the first reference surface, and the surface below the base segment and the bearing segment is the second reference surface; the first reference surface and the second reference surface are parallel.

[0007] The step height difference h2 between the base section and the bearing section is greater than the cone height h1 on the upper mold; the thickness h3 of the base section is less than the total height H of the cone on the upper mold and the working zone of the upper mold.

[0008] Furthermore, the base segment has two mounting holes on its body from the first reference surface, and each mounting hole contains a strong magnet; the surface of the strong magnet is lower than or flush with the first reference surface.

[0009] Furthermore, the step height difference h2 between the base section and the bearing section is 8mm to 9mm.

[0010] Furthermore, the thickness h3 of the substrate segment is 16mm to 18mm.

[0011] Furthermore, the material of the strip is H13 steel.

[0012] The beneficial effects of the technical solution provided by this utility model embodiment are: this utility model cleverly avoids the cone on the upper mold, so that the measuring square can be placed against the upper mold working belt to facilitate the measurement of the verticality of the upper mold working belt; this utility model has a simple and easy-to-use structure and solves the technical problems encountered in actual production.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0018] like Figure 1 and Figure 2 As shown in the figure, this utility model embodiment proposes an auxiliary tooling for detecting the verticality of the upper die working zone of an aluminum alloy extrusion die, including a strip 10, wherein the strip 10 includes an integrally constructed base section 101 and a bearing section 102;

[0019] The thickness h4 of the bearing section 102 is less than the thickness h3 of the base section 102, so that there is a gap 103 above the bearing section 102 relative to the base section 101; in the gap 103, the step height difference between the base section 101 and the bearing section 102 is h2.

[0020] The surface above the base segment 101 is the first reference surface A, and the surface below the base segment 101 and the bearing segment 102 is the second reference surface B; the first reference surface A and the second reference surface B are parallel.

[0021] like Figure 3As shown, the upper mold 20 of the mold is provided with a mold reference surface 201, and a cone 202 is provided on the mold reference surface 201. The upper mold working belt 203 is connected above the cone 202.

[0022] The step height difference h2 between the base section 101 and the bearing section 102 is greater than the height h1 of the cone 202 on the upper mold 20; the thickness h3 of the base section 101 is less than the total height H of the cone 202 on the upper mold 20 and the upper mold working belt 203.

[0023] like Figure 4 As shown, in use, the first reference surface A of the strip 10 and the mold reference surface 201 are attached. Since the height of the notch 103 (i.e. the step height difference h2 between the base section 101 and the bearing section 102) is greater than the height h1 of the cone 202 on the upper mold 20, the tooling can avoid the cone 202 on the upper mold 20. Therefore, the side of the bearing section 102 can be close to or attached to one of the upper mold working strips 203 on the upper mold 10. The square can be placed on the second reference surface B of the bearing section 102 to measure the perpendicularity of the upper mold working strip 203.

[0024] More preferably, the base segment 101 has two mounting holes extending from the first reference surface A into the body of the base segment 101, and each mounting hole contains a strong magnet 104; the surface of the strong magnet 104 is lower than or flush with the first reference surface A; through the strong magnet 104, the tooling can be attracted to the mold reference surface 201 of the upper mold 20, and whether the upper mold 20 is placed flat or vertically, the first reference surface A of the strip 10 can fit well with the mold reference surface 201.

[0025] In one specific embodiment, the step height difference h2 between the base segment 101 and the bearing segment 102 is 8mm to 9mm to avoid the cone 202 on the upper mold 20.

[0026] In one specific embodiment, the thickness h3 of the base segment 101 is 16mm to 18mm, such that the thickness h3 of the base segment 101 is less than the total height H of the cone 202 and the working belt 203 on the upper mold 20.

[0027] In one specific embodiment, the material of the strip 10 is H13 steel; it has sufficient strength to ensure that the load-bearing section 102 will not bend or deform.

[0028] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
