Description

Technical Field

[0001] The invention relates to the technical field of aluminum profile extrusion production, and in particular to an aluminum profile shaping device and an aluminum profile production process. Background Art

[0002] At present, there may be various reasons for the undesirable conditions of product deformation and size deviation during the extrusion production of aluminum profiles, such as uneven surface, concave surface, convex surface, opening size closing, opening, square tube bevel, round tube ellipse, etc. In fact, when these undesirable conditions occur, the general action taken is to stop production, consider adjusting the mold first, and then re-test the mold after the mold is repaired. If the mold is not repaired once, it must be repaired a second time until the trial mold product is qualified before production.

[0003] However, after stopping production, the following problems will occur:

[0004] 1. Each time the mold is re-tested, the machine needs to be restarted, which consumes electricity and is costly; each mold test wastes 1 to 3 aluminum bars; after each mold test, the mold must be boiled with strong caustic soda before it can be repaired, which takes a long time and is not environmentally friendly; each mold repair takes 1 to 3 days before the machine can be re-tested and it may not be successful, which is inefficient and slow.

[0005] 2. Even after the mold is repaired and can be put into normal production, there may be other factors (such as deformation of the mold during extrusion due to long-term use, excessive temperature rise of the ingot during extrusion, too fast change in extrusion speed, improper control of elongation during stretching and straightening, etc.) that lead to dimensional deviations and a decrease in the qualified rate of finished products.

[0006] 3. The shaping process using a traditional roller shaping machine is usually to cut the product and then shape it one by one, which is inefficient. Since there is no extruder to provide thrust, the shaping effect is average. Summary of the invention

[0007] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present invention is to provide an aluminum profile shaping device and an aluminum profile production process, which can adjust common deformation tolerances such as uneven surface, concave surface, convex surface, opening size closing, opening, square tube bevel, and round tube ellipse by applying external force to the product during the production of aluminum profiles, thereby achieving high efficiency of adjustment during production, thereby reducing the number of mold trials and improving production efficiency and product qualification rate.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0029] At present, there may be various reasons for the undesirable conditions of product deformation and size deviation during the extrusion production of aluminum profiles, such as uneven surface, concave surface, convex surface, opening size closing, opening, square tube bevel, round tube ellipse, etc. In fact, when these undesirable conditions occur, the general action taken is to stop production, consider adjusting the mold first, and then re-test the mold after the mold is repaired. If the mold is not repaired once, it must be repaired a second time until the trial mold product is qualified before production.

[0030] However, after stopping production, the following problems will occur:

[0031] 1. Each time the mold is re-tested, the machine needs to be restarted, which consumes electricity and is costly; each mold test wastes 1 to 3 aluminum bars; after each mold test, the mold must be boiled with strong caustic soda before it can be repaired, which takes a long time and is not environmentally friendly; each mold repair takes 1 to 3 days before the machine can be re-tested and it may not be successful, which is inefficient and slow.

[0032] 2. Even after the mold is repaired and can be put into normal production, there may be other factors (such as deformation of the mold during extrusion due to long-term use, excessive temperature rise of the ingot during extrusion, too fast change in extrusion speed, improper control of elongation during stretching and straightening, etc.) that lead to dimensional deviations and a decrease in the qualified rate of finished products.

[0033] 3. The shaping process using a traditional roller shaping machine is usually to cut the product and then shape it one by one, which is inefficient. Since there is no extruder to provide thrust, the shaping effect is average.

[0034] In order to solve the above problems, this embodiment discloses an aluminum profile shaping device, the structure of which is as follows: Figure 1 As shown, the shaping device includes a device body 100, a plurality of shaping components 101 movably arranged on the device body 100, and a pressing mechanism (not shown in the figure) for pressing the shaping component 101; the pressing mechanism applies an external force to the outer end of the shaping component 101, so that the inner end of the shaping component 101 acts on the external aluminum profile to achieve the shaping of the aluminum profile.

[0035] In addition, this embodiment also discloses an aluminum profile production process, which includes the following steps:

[0036] S100. Aluminum products are processed from the extruder 201 into aluminum profiles, and the aluminum profiles are transported to the aluminum profile shaping device via the track 202;

[0037] S200. According to the position of the aluminum profile deformation and the shape of the product, select the corresponding position of the shaping rod 103 or shaping plate 105;

[0038] S300. The pressing mechanism drives the shaping rod 103 or the shaping head 104 on the shaping plate 105 to press and adjust the deformation position of the aluminum profile.

[0039] Furthermore, the shaping head 104 can be designed according to the shape of the aluminum product, and the shaping rod 103 or the shaping plate 105 can be replaced with shaping heads of various shapes.

[0040] In this embodiment, after the aluminum profile is processed by the extruder 201, it is transported outward through the track 202; and the device body 100 of this embodiment is an arch bridge shape or a tubular structure, that is, the aluminum profile passes through the inside of the device body 100 along the track 202, and when the aluminum profile passes through the device body 100, external forces in multiple directions are applied to the aluminum profile to shape it, and the pressing mechanism is preferably a hydraulic press; in addition, the pressing mechanism and the shaping rod 103 (or the shaping plate 105) of this embodiment can be replaced by a manipulator, and the shaping head 104 is installed at the end of the manipulator, which can also play the effect of adjusting the deformation position of the aluminum profile by pressing.

[0041] Specifically, the device body 100 is provided with positioning holes 102 corresponding to the shaping components 101 one by one, and the shaping components 101 are movably arranged at the corresponding positioning holes 102 .

[0042] Furthermore, the positioning hole 102 is as follows Figure 1 The circular hole structure or strip structure shown, that is, the shaping component 101 in this embodiment includes a shaping rod 103 (or a shaping plate 105), and a shaping head 104. The shaping head 104 is generally made of a high-temperature resistant lubricating material, such as graphite, and components with less friction such as wheels can also be used; the rod (plate) body of the shaping rod 103 (plate) is slidably connected to the positioning hole 102, and the shaping head is arranged at the inner end of the shaping rod (plate).

[0043] In this embodiment, the shaping components 101 and the positioning holes 102 are distributed on the device body 100 according to corresponding rules, and the positioning holes 102 of different shapes correspond to the shaping rods 103 (or shaping plates 105) with different stress conditions; by observing the deformation out-of-tolerance position and product shape of the aluminum profile produced by the extruder 201, a suitable shaping head is selected from shaping heads of different shapes and installed on the shaping rod or shaping plate, and the shaping rod or shaping plate is inserted into the corresponding positioning hole 102 of the device body 100, and the shaping rod or shaping plate at the corresponding position is controlled by pressing with external force to adjust the deformation position.

[0044] Furthermore, the shaping component 101 also includes a positioning head 106 arranged at the outer end of the shaping rod 103, which facilitates the coordinated installation of the positioning rod and the external pressing mechanism and improves the accuracy of pressing the profile.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
