[0002] Aluminum tubes are a type of non-ferrous metal tube, referring to metal tubular materials made of pure aluminum or aluminum alloy through extrusion processing, which are hollow along their entire longitudinal length. They may have one or more closed through holes, and the wall thickness and cross-section are uniform. They are delivered in straight lines or in coils and are widely used in the automotive, shipbuilding, aerospace, aviation, electrical appliances, agriculture, electromechanical, and home furnishing industries. The wall thickness and cross-section of aluminum tubes are generally consistent. When aluminum tubes are used to connect components, they need to be flared.

[0003] Existing flaring machines can usually only flare aluminum tubes of the same specification. When flaring aluminum tubes with larger or smaller diameters is required, different flaring machines are needed, which reduces the efficiency of flaring aluminum tubes.

A flaring mold is fixedly connected to the working end of the hydraulic drive mechanism. A protective mechanism is provided between the hydraulic drive mechanism and the pressure base frame, including a protective inner pressure frame and an operating rotating frame. This utility model allows four driven square rods to move closer to each other under the push of compression springs, clamping and protecting the internally inserted aluminum tube, reducing the occurrence of cracking caused by the flaring mold during aluminum tube flaring.

[0005] The cited patent still has the drawback of not being able to flare aluminum tubes of different specifications. Therefore, we need to propose an aluminum tube flaring machine. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 This utility model provides a technical solution: an aluminum tube flaring machine, comprising:

[0028] Workbench 1, and flaring assembly 2, limiting assembly 3 and aluminum tube clamping assembly 5 installed on the upper surface of workbench 1, the flaring assembly 2 facilitates the flaring of the aluminum tube clamped by aluminum tube clamping assembly 5.

[0029] An adjusting component 4 is installed on the lower surface of the workbench 1 to adjust the position of the aluminum tube clamping assembly 5. The spacing of the aluminum tube clamping assembly 5 is adjusted by the adjusting component 4 to achieve clamping and fixing of aluminum tubes of different specifications.

[0030] The aluminum tube clamping assembly 5 mainly consists of two sets of clamping parts arranged symmetrically, and the two sets of clamping parts are installed at both ends of the adjusting assembly 4.

[0031] The clamping component includes a connecting plate 51 and clamping blocks 52 fixedly connected to both sides of the connecting plate 51. Each of the two sets of clamping blocks 52 has a clamping groove 53 for clamping the aluminum tube on one side. The inner wall of the clamping groove 53 is bonded with a buffer pad 54 to reduce rigid clamping. Each of the two sets of clamping blocks 52 is fixedly connected to an insert plate 55 to support the aluminum tube on the side adjacent to the clamping groove 53. The buffer pad 54 can prevent the rigid clamping from damaging the aluminum tube during clamping, improve the stability of clamping the aluminum tube, and the insert plate 55 is inclined to lift the aluminum tube, thereby facilitating the clamping of the aluminum tube and improving the convenience of clamping.

[0032] A protective cover 56 is fixedly connected to one side of the clamping block 52 adjacent to the clamping groove 53. A bottom block 57 is fixedly connected to the lower surface of both sets of clamping blocks 52. A bottom groove 8 is opened on the upper surface of the workbench 1 for the bottom block 57 to slide and install. Two sets of directional rods 9 for guiding the bottom block 57 are fixedly connected in the bottom groove 8. By sliding the bottom block 57 along the directional rods 9 in the bottom groove 8, the stability of the clamping block 52 when moving is improved, thereby improving the stability of clamping the aluminum tube. The protective cover 56 can prevent the aluminum tube from splashing during flaring, thus improving the safety during flaring.

[0033] The adjustment assembly 4 includes a dual-axis motor 41 mounted on the lower surface of the workbench 1. The two output ends of the dual-axis motor 41 are respectively connected to screws 42 with opposite thread directions. Both ends of the two screws 42 are threadedly connected to a connecting frame 44. The end of the connecting frame 44 opposite to the screws 42 is fixedly connected to a fixing block 45 welded to the connecting plate 51. The lower surface of the workbench 1 is fixedly connected to a guide frame 43 for the connecting frame 44 to slide. The position of the connecting frame 44 can be easily adjusted by driving the screws 42 through the dual-axis motor 41, so that the connecting frame 44 slides along the guide frame 43, which improves the stability of the movement of the connecting frame 44, thereby improving the stability of the movement of the aluminum tube clamping assembly 5.

[0034] The flaring assembly 2 includes a fixed plate 21 mounted on the upper surface of the workbench 1. A hydraulic cylinder 22 is mounted on one side of the fixed plate 21. An installation plate 23 is fixedly connected to the output end of the hydraulic cylinder 22. A rotary motor 24 is provided on one side of the installation plate 23. A flaring mold 25 for flaring aluminum tubes is mounted on the output end of the rotary motor 24. Guide beams 26 that penetrate the fixed plate 21 are fixedly connected to both sides of the installation plate 23. The hydraulic cylinder 22 can easily drive the fixed plate 21 to move horizontally, thereby enabling the flaring mold 25 driven by the rotary motor 24 to flare the end of the aluminum tube. At the same time, the flaring mold 25 is mainly composed of a limiting disc and a conical flaring head, which can slowly flare the aluminum tube to avoid cracking of the aluminum tube due to excessive flaring speed. At the same time, the rotation of the flaring mold and the friction with the aluminum tube generate heat, thereby further improving the plastic deformation of the aluminum tube opening. A controller 10 that drives the hydraulic cylinder 22, the rotary motor 24 and the dual-axis motor 41 is installed on one side of the workbench 1.

[0035] The limiting component 3 includes a limiting plate 31, a slider 32 is fixedly connected to the lower surface of the limiting plate 31, a locking bolt 33 is threadedly connected to the slider 32, and a shaft 34 is fixedly connected to one side of the limiting plate 31. The limiting plate can support the other end of the aluminum tube, thereby preventing the aluminum tube from moving during the opening process and improving the quality of the aluminum tube opening.

[0036] The upper surface of the workbench 1 is provided with a slide groove 6 for the slider 32 to slide. The bottom of the slide groove 6 is provided with multiple sets of positioning holes 7 for the locking bolts 33 to be inserted. The axis of the flaring mold 25, the axis of the shaft 34 and the axis of the aluminum tube clamping assembly 5 are all set on the same axis. The positioning holes 7 facilitate the installation of the locking bolts 33. In addition, the different positions of the limiting plate 31 are suitable for aluminum tube openings of different lengths, which improves practicality. By setting the axes of the three on the same axis, it is convenient to flare the aluminum tube and reduce the amount of work required to adjust the position of the aluminum tube.

[0037] In use, the aluminum tube to be flared is placed between the aluminum tube clamping components 5 on the workbench 1. The controller 10 controls the start and stop of the dual-axis motor 41, so that the dual-axis motor 41 drives the screw 42 to adjust the distance between the two sets of connecting parts closer together. This allows the connecting frame 44 to drive the connecting plate 51 closer together through the fixing block 45, so that the insert plate 55 on the clamping block 52 supports the aluminum tube, thereby moving the aluminum tube into the clamping groove 53 of the clamping block 52. The aluminum tube is then clamped by the buffer pad 54, so that the axis of the aluminum tube coincides with the axis of the opening mold. Then, the limiting plate 31 is adjusted to abut against one end of the aluminum tube, and the locking bolt 33 is screwed into the corresponding positioning hole 7 to prevent the limiting plate 31 from moving, thereby supporting the aluminum tube and preventing the aluminum tube from moving during the opening process. The hydraulic cylinder 22 drives the fixing plate 21 to move, and at the same time, the rotary motor 24 drives the opening mold to rotate, so that the opening mold opens the aluminum tube while rotating. The heat generated by the rotational friction softens the aluminum tube, thereby better helping the aluminum tube to be shaped and improving the opening efficiency of the aluminum tube.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
