Description

Technical Field

[0001] This utility model belongs to the field of aluminum alloy extrusion die technology, and relates to the assembly technology of aluminum alloy extrusion dies, especially an auxiliary tool for assembling aluminum alloy extrusion dies. Background Technology

[0002] Aluminum alloy extrusion dies are an important component in the production of aluminum alloy profiles, such as... Figure 3 As shown, during overall assembly, component 12 needs to be fitted onto end 11 of component 10, and the component and component 10 are fixed together by their internal and external threads. In specific assembly, the component is first fitted onto... Figure 4 Inside the sleeve 6 of the auxiliary tool shown, after aligning the position, tighten the fixing bolt 3 so that the end 5 of the fixing bolt engages in the threaded hole 13 provided on the outer circumferential surface of the component, thereby fixing the auxiliary tool and the component. Lift the auxiliary tool, align the component with component one, and rotate the sleeve by rotating the rotating rod 1, causing the sleeve to rotate and gradually engage with the end of component one. In actual use, it was found that because the component is heavy, operators need to use tools such as extension tubes and pry bars to rotate the component. The sleeve being placed on the rotating rod or the pry bar prying the fixing bolt will subject the rotating rod to significant force, which over time can cause the rotating rod to tilt, and in severe cases, even break. This necessitates repair or replacement of the auxiliary tool, affecting mold assembly. Utility Model Content

Detailed Implementation

[0015] The present invention will be further described in detail below through specific embodiments. The following embodiments are only descriptive and not limiting, and should not be used to limit the protection scope of the present invention.

[0016] An auxiliary tool for assembling an aluminum alloy extrusion die includes a sleeve 6, a fixing bolt 3, and a rotating rod 1, as shown in the figure. Multiple fixing tubes 4 are evenly distributed on the outer circumferential surface of the sleeve. A fixing bolt is screwed into the inside of each fixing tube. The end 5 of each fixing bolt can extend into the cavity 8 inside the sleeve. A rotating tube 2 is provided on the sleeve between two adjacent fixing tubes. A rotating rod is provided inside each rotating tube.

[0017] A reinforcing plate 7 is installed between the fixed tube and the rotating tubes on both sides. Each reinforcing plate is as follows: Figure 1 As shown, the reinforcing plates are welded to the surfaces of the fixed and rotating tubes on the same side, respectively, and the surface of the reinforcing plate near the sleeve is welded to the outer circumferential surface of the sleeve. After all the reinforcing plates are connected, they form the following structure: Figure 1 The diagram shows a roughly octagonal structure that integrates the sleeve, fixed tube, and rotating tube into one unit, thus better distributing localized forces across the overall structure.

[0018] Sleeves Figure 2 As shown, one end is rotatably fitted inside an outer sleeve 14. A bearing (not shown in the figure) is provided between the outer sleeve and the sleeve. The inner ring of the bearing is fitted on the outer circumferential surface of the sleeve, and the outer ring of the bearing is installed on the inner wall of the outer sleeve. Balls or rollers are provided between the inner and outer rings. The bearing installation method, how the sleeve and outer sleeve are fixed and positioned with the inner and outer rings are all existing technologies and will not be described in detail here.

[0019] The sleeve is made of metal and has a certain thickness and height. Four openings are evenly distributed radially on the sleeve. A fixing tube is welded to the opening of each opening on the outer circumferential surface of the sleeve, and a total of four fixing tubes are installed. Internal threads are formed inside the fixing tubes and openings, which engage with the external threads of the fixing bolts. The end of the fixing bolt extends into the cavity inside the sleeve and can be screwed into the threaded hole 13 aligned with the outer circumferential surface of the component 12 fitted inside the sleeve.

[0020] Four through holes are evenly distributed on the surface of the sleeve between the two fixed tubes. A rotating tube is welded to the opening of each through hole on the outer circumferential surface of the sleeve, and a total of four rotating tubes are installed. A rotating rod is fixed inside the rotating tube and the through hole, which can be fixed by welding or screwing. The end of the rotating rod is located inside the through hole or flush with the opening of the through hole on the inner surface of the sleeve cavity.

[0021] The axial length of the rotating tube is longer than the axial length of the fixed tube, such as... Figure 1 As shown, the rotating tube between the two reinforcing plates extends outward by a certain length, and the rotating rod is also a little longer than the fixing bolt, thus forming a longer lever arm, which reduces the force required to a certain extent.

[0022] The outer circumferential surface of the sleeve is provided with outward-facing lifting lugs 9, which are used to lift the entire sleeve.

[0023] The working process of this utility model is as follows: Loosen the fixing bolts so that the ends of the fixing bolts return to the opening. Lay the sleeve flat and lift part 12 so that it enters the sleeve (the inner diameter of the sleeve is larger than the outer diameter of the part). Align the threaded hole with the opening.

[0024] Tighten the fixing bolts so that their ends engage in the threaded holes, thus securing the components and sleeves.

[0025] Lift the sleeve using the lifting lugs and move it slowly until the component is aligned with end 11 of component two 10. Hold the rotating tube and rotate the sleeve, and the component will gradually screw onto end 11 of component two. When tightening, the extension tube can be fitted onto the rotating tube to create a longer lever arm, and then force can be applied to tighten the component.

[0026] In this invention, fixed tubes and rotating tubes are radially evenly distributed in the middle of the outer circumferential surface of the sleeve. A reinforcing plate connects the fixed tubes and the rotating tubes, and the reinforcing plate is also connected to the outer circumferential surface of the sleeve. A fixing bolt is screwed into the fixed tube, and a rotating rod is installed inside the rotating tube. When the component is fitted into the sleeve, the sleeve and the component are connected by tightening the fixing bolt. Then, the rotating rod drives the sleeve to rotate, tightening the component onto the end of component one. The reinforcing plate connects the fixed tube, rotating tube, and sleeve into a whole, distributing the force acting on the rotating rod to the sleeve through the rotating rod and reinforcing plate, thus solving the problems of skewing and breakage caused by excessive force on the rotating rod in traditional technology, and improving service life. The sleeve is rotatably fitted inside the outer sleeve, which is equipped with lifting lugs to lift the sleeve and the component. A bearing is installed between the sleeve and the outer sleeve, allowing the sleeve to rotate inside the outer sleeve and complete the installation of the component.
