Description

Technical Field

[0001] The utility model relates to the technical field of profile processing, in particular to a triangular extruded profile cavity supporting device. Background Art

[0002] Among the existing rail transit aluminum alloy structural parts, large-sized triangular extruded aluminum alloy profiles are a very important part of the chassis structure. Large-sized triangular extruded aluminum alloy profiles use pure aluminum as the matrix and add one or more other metal or non-metal elements to form an alloy material with metallic properties. After extrusion, the product has a triangular product with an circumscribed circle diameter of more than 320 mm.

[0003] Large-sized triangular extruded aluminum alloy profiles have large specifications and thick walls. During the extrusion molding process, the gap between the bevel edges of the triangular profiles is often affected by uneven online quenching and cooling and the straightening process, resulting in excessive gaps in the product. Triangular profiles with excessive gaps reduce the product yield, and during the splicing process, multiple triangular profiles of poor size are difficult to use together, affecting the product delivery schedule.

[0004] The current profile inner cavity shaping equipment (such as publication number CN212884232U) is mostly used for inner cavity shaping of rectangular profiles. Generally, only a number of shaping wheel groups are arranged in the length direction of the side plate, and the use of shaping wheels to synchronously support all surfaces is not considered, which can easily cause scratches on unsupported surfaces. In addition, the shaping wheels of the existing profile inner cavity shaping equipment are conventional columnar structures and can only be applied to the inner cavity correction of ordinary profiles, but not to triangular profiles. When the columnar shaping rod pushes against the deformed surface, the two ends of the roller will make grooves on the deformed surface. Utility Model Content

[0032] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0033] In a typical implementation of the present invention, Figure 1-Figure 9As shown, a triangular extruded profile supporting device is proposed, comprising: a frame, the cross-section of the frame is triangular, and the cross-section of the frame in this embodiment is an isosceles triangle, the frame contains a bottom surface and two side surfaces, wherein a plurality of supporting rollers 5 are provided on one side surface along the axial interval to rotate, the supporting rollers 5 are spindle-shaped structures with diameters at both ends smaller than the diameter in the middle, that is, the diameter of the supporting rollers 5 gradually decreases from the middle to both ends, so as to use the protrusion in the middle to support the side of one hypotenuse of the deformed triangular extruded profile, so as to correct the deformed triangular profile so that the hypotenuse gap meets the requirements; a plurality of first supporting rollers 6 are provided on the other side surface along the axial interval to rotate for contacting the side wall of the other hypotenuse of the triangular profile; a plurality of second supporting rollers 7 are provided on the bottom surface of the frame along the axial interval to contact the bottom side wall of the triangular profile.

[0034] It is understandable that the cross-sectional shape of the frame is the same as the cross-sectional shape of the inner cavity of the actual triangular profile, and no excessive restrictions are imposed on the specifics here.

[0035] The frame includes a triangular plate-shaped base 1, a first fixed axis 2, a second fixed axis 3 and a third fixed axis 4, wherein the base 1 is provided with two, the two bases 1 are arranged oppositely, the first fixed axis 2, the second fixed axis 3 and the third fixed axis 4 are fixedly installed between the two bases 1, the first fixed axis 2 is provided with one, the first fixed axis 2 is fixedly installed between the two bases 1, and the first fixed axis 2 is located at the top corner of the base 1; the second fixed axis 3 is provided with three, wherein two second fixed axes 3 are staggered and fixedly installed at one bottom corner of the base 1, and another second fixed axis 3 is fixedly installed at another bottom corner of the base 1; the third fixed axis 4 is provided with one, the third fixed axis 4 is fixedly installed at the bottom corner where the second fixed axis 3 is provided on the base 1, and the third fixed axis 4 is staggered with the second fixed axis 3 adjacent to it, a plurality of top support rollers 5 are rotatably arranged between the first fixed axis 2 and an opposite second fixed axis 3, a plurality of second support rollers 7 are rotatably arranged between the two oppositely arranged second fixed axes 3, and a plurality of first support rollers 6 are rotatably arranged between the third fixed axis 4 and the first fixed axis 2, wherein the top support rollers 5 and the first support rollers 6 are alternately arranged along the axial direction of the cavity support device on the horizontal projection plane.

[0036] like Figure 2 As shown, rectangular first mounting holes 8 are provided at the top corner and the two bottom corners of the base 1, wherein one first mounting hole 8 is provided at the top corner, and two staggered first mounting holes 8 are provided at the two bottom corners for fixed installation of the first fixed axis 2, the second fixed axis 3 and the third fixed axis 4.

[0037] like Figure 3As shown, a mounting body 9 is fixedly provided at both ends of the first fixed shaft 2, and the cross-section of the mounting body 9 is rectangular. The cross-sectional size of the mounting body 9 is the same as the cross-sectional size of the first mounting hole 8, and the thickness of the mounting body 9 is the same as the axial length of the first mounting hole 8 (i.e., the thickness of the base 1). The cross-sectional size of the mounting body 9 is smaller than the cross-sectional size of the first fixed shaft 2, which plays a positioning role. A stud 10 is fixedly provided on the mounting body 9 for connection with a nut. A plurality of second mounting holes 11 and third mounting holes 12 are spaced apart along the axial direction of the first fixed shaft 2, wherein the second mounting holes 11 and the third mounting holes 12 are staggered side by side for respectively installing the rotating shafts of the top support roller 5 and the first support roller 6.

[0043] The first supporting roller 6 and the second supporting roller 7 may be of equal length or of unequal length, which may be determined according to the structure of the actual profile, and no excessive restrictions are imposed here.

[0044] The axial directions of the top support roller 5, the first support roller 6 and the second support roller 7 are perpendicular to the moving direction of the cavity support device, so that they contact the side wall of the profile in a rolling manner to reduce damage to the inner surface of the profile.

[0045] A connecting portion is also provided at the middle position of the base 1, and the base 1 can be connected to a winch through the connecting portion and a pull rope to drive the overall movement of the cavity support device.

[0046] The specific working principle is: the cavity supporting device is placed in the triangular pressurized profile, so that the top supporting roller 5 of the cavity supporting device contacts the deformed surface of the profile, the first supporting roller 6 is used to contact the opposite side of the deformed surface, and the second supporting roller 6 is used to contact the third surface of the profile, and the cavity supporting device is pulled to move inside the profile along the length direction of the profile. During the movement, the top supporting roller 5 is used to prop up the deformed surface of the profile, so that the profile gap is effectively improved to meet the original design requirements of the product.
