Description

Technical Field

[0001] This utility model relates to a straightening fixture, specifically a straightening fixture for hard aluminum alloy profiles. Background Technology

[0002] With the development of the aluminum extrusion industry, aluminum extruded products are becoming increasingly common in the manufacturing sector, and their shapes are becoming more diverse and complex as the applications expand. Currently, the general process flow for aluminum extrusion is: bar preheating → extrusion → straightening → cutting. During the straightening process of hard aluminum profiles, the following problems commonly exist:

[0003] 1. For complex-shaped profiles, the ends are prone to tearing and slipping, making them impossible to clamp.

[0004] 2. The product cannot be straightened.

[0005] 3. If the product breaks, it poses a safety hazard. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a straightening fixture for hard aluminum alloy profiles. This hard aluminum alloy profile straightening fixture features a simple structure and easy operation, effectively improving the production efficiency and yield of online straightening. It is mainly applied to profiles with complex cross-sections such as 4-series and 7-series hard aluminum alloys.

[0007] To achieve the above technical objectives, the technical solution adopted in this utility model embodiment is as follows:

[0008] A straightening fixture for hard aluminum alloy profiles is integrally formed. The straightening fixture has a profile interlocking surface and a straightening machine interlocking surface. The profile interlocking surface is used to interlock and fix the surface of the profile, and the straightening machine interlocking surface is used to interlock and fix the straightening fixture on the straightening machine.

[0009] Furthermore, the mating surface of the profile is an arc surface with spaced protrusions and recesses, the protrusions being in contact with the surface of the profile.

[0010] Furthermore, adjacent protrusions and adjacent recesses are equally spaced, and both the protrusions and recesses have a certain width and are arranged parallel to the surface of the profile.

[0011] Furthermore, the meshing surface of the straightening machine is a plane with uniformly distributed V-grooves, and the straightening fixture is meshed with the straightening machine through the V-grooves.

[0012] Furthermore, the chord length of the profile interlocking surface is less than the width of the straightening machine interlocking surface.

[0013] Furthermore, the profile is an aluminum alloy profile.

[0014] The beneficial effects of the technical solution provided by this utility model embodiment are:

[0015] 1. The shape of this utility model straightening fixture is designed according to the cross-section of aluminum alloy profiles. In particular, the interlocking surface of the profile is closely fitted to the profile, so the product profile is subjected to uniform force during straightening, and the product will not be deformed, ensuring product quality. Furthermore, the profile straightening process is safer and can significantly reduce waste caused by product defects.

[0016] 2. The straightening fixture of this utility model has a profile interlocking surface and a straightening machine interlocking surface. Since the straightening fixture, the profile, and the straightening machine are all engaged in an interlocking manner, there will be no slippage or tearing between the straightening fixture, the straightening machine, and the profile, making the production process safer and more efficient.

[0020] In the description of this utility model, it should be understood that the directional terms such as "inner" and "outer", "upper" and "lower", "left" and "right" indicate the orientation or positional relationship, which are usually based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of this utility model.

[0021] 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.

[0022] Example 1

[0023] like Figure 1 and 2As shown, a straightening fixture for hard aluminum alloy profiles is provided. The straightening fixture 1 is integrally formed and has a profile engagement surface 1A and a straightening machine engagement surface 1B. The profile engagement surface 1A is used to engage and fix the surface of the profile 2, and the straightening machine engagement surface 1B is used to engage and fix the straightening fixture 1 on the straightening machine.

[0024] The profile mating surface 1A is an arc surface with spaced protrusions 11 and recesses 12. The protrusions 11 are in contact with the surface of the profile 2. The protrusions 11 and recesses 12 increase the friction between the profile mating surface 1A and the profile, and increase the biting force between the profile 2 and the profile mating surface 1A of the straightening fixture 1. This prevents slippage and tearing between the straightening fixture 1 and the profile 2 during the straightening process, making the production process safer and more efficient.

[0025] Adjacent protrusions 11 and adjacent recesses 12 are equally spaced, and both protrusions 11 and recesses 12 have a certain width and are arranged parallel to the surface of profile 2. The equal spacing of adjacent protrusions 11 and adjacent recesses 12 ensures that the stress on each part is uniform during the straightening process of profile 2, preventing product deformation and ensuring product quality.

[0026] The straightening machine's meshing surface 1B is flat and has evenly distributed V-grooves 13. The straightening fixture 1 is connected to the straightening machine through the V-grooves 13. The V-grooves 13 increase the meshing force between the straightening fixture 1's meshing surface 1B and the straightening machine, preventing slippage and tearing between the straightening machine and the profile 2 during the straightening process, making the production process safer and more efficient.

[0027] The chord length of the profile interlocking surface 1A is less than the width of the straightening machine interlocking surface 1B, which facilitates easy disassembly between the profile 2 and the straightening fixture 1.

[0028] Profile 2 is an aluminum alloy profile. Specifically, profile 2 is a hard aluminum alloy profile, including profiles with complex cross-sections of hard aluminum such as 4-series and 7-series.

[0029] During operation, the operator places the straightening fixture 1 on the lower jaw of the straightening machine, ensuring that the straightening machine's meshing surface 1B of the straightening fixture 1 is properly engaged with the lower jaw of the straightening machine. Then, one end of the profile 2 is moved and placed on the straightening fixture 1, ensuring that the profile 2 is properly engaged with the profile meshing surface 1A of the straightening fixture 1. The same operation is repeated on the other end of the profile 2. After both ends of the profile 2 are in place, the straightening operation is performed. After straightening is completed, the straightening fixture 1 is removed, and the next operation is performed according to the process requirements.

[0030] 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 examples, 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.
