DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described and illustrated in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Based on the embodiments provided by the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0033] Obviously, the drawings described below are only some examples or embodiments of the utility model. For ordinary technicians in this field, the utility model can also be applied to other similar scenarios based on these drawings without creative work. In addition, it can be understood that although the efforts made in this development process may be complicated and lengthy, for ordinary technicians in this field related to the content disclosed by the utility model, some changes in design, manufacturing or production based on the technical content disclosed by the utility model are just conventional technical means, and should not be understood as the content disclosed by the utility model is insufficient.

[0034] Reference to "embodiments" in the present invention means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present invention may be combined with other embodiments without conflict.

[0035] like Figure 1 As shown, a combined bending sliding mold is characterized by comprising: a base and a plurality of combined blocks, such as a first combined block 21, a second combined block 22, and a third combined block 23 in this embodiment, wherein:

[0036] The base, the upper end of which is connected to the sliding form drive mechanism of the bending machine, such as the connection 102 with the sliding form drive mechanism; it can be understood that the sliding form drive mechanism 4 of the bending machine drives the base to move left and right in the plane to transport the aluminum tube.

[0037] A plurality of assembly blocks, each assembly block is connected to the base 1. For example, in this embodiment, the first assembly block 21, the second assembly block 22, and the third assembly block 23 are all connected to the base 1. The base 1 and the assembly blocks are detachably connected. The front end of the assembly block is provided with a clamping groove 204 for clamping the aluminum tube 3, and the clamping groove 204 is adapted to the aluminum tube 3.

[0038] The lengths and / or widths of the plurality of assembly blocks are different to adapt to the aluminum tubes 3 of different working conditions. It is understandable that assembly blocks of different sizes are used according to the different aluminum tubes to be bent. For example, when the aluminum tube 3 includes a welding joint 302, the width of the second assembly block 22 and its adjacent assembly blocks can be smaller, so that the gap between the second assembly block 22 and its adjacent assembly blocks is larger to accommodate the welding joint 302.

[0039] For another example, when the effective bending portion 304 on the aluminum tube 3 is shorter, the first assembly block 21 , the second assembly block 22 , the third assembly block 23 and the base adopt a narrower structure and move downward at the same time to clamp the aluminum tube 3 at the bottom.

[0040] The scheme provides a combined bending sliding mold, which is detachably connected by a base and a combined block. The combined block can be replaced to adapt to aluminum tubes in different working conditions, thereby improving the applicability of the device.

[0041] like Figure 2 , Figure 3 As shown, in other embodiments, the lower end of the base 1 is provided with a boss 101, the upper end of the assembly block is provided with a groove 201, and the boss 101 is inserted into the groove 201 to complete the connection and fixation between the base and the assembly block. This embodiment realizes a detachable connection between the assembly block and the base.

[0042] like Figure 2 , Figure 3As shown, the side of the boss 101 is provided with a plurality of first threaded holes 103, and the side of the groove 201 is provided with a second threaded hole 202, and the first threaded holes 103 are matched with the second threaded holes 202. It can be understood that the first threaded holes 103 and the second threaded holes 202 are connected by screws 203, that is, the base 1 and the assembly block are connected and fixed.

[0043] like Figure 2 , Figure 3 As shown, in other embodiments, the number of the first threaded holes 103 is greater than or equal to the sum of the number of the second threaded holes 202. It is understandable that when the width adjustment of the assembly block cannot meet the gap requirement, the distance between two adjacent assembly blocks can be adjusted by fixing the assembly block to other first threaded holes 103. This solution achieves the adjustment of the distance between assembly blocks.

[0044] like Figure 3 As shown, in other embodiments, the clamping groove 204 is a C-shaped structure. It can be understood that the C-shaped structure clamps the aluminum tube stably. This solution achieves the clamping and fixing of the aluminum tube.

[0045] like Figure 3 As shown, in other embodiments, the diameters of the multiple C-shaped structures are different. It can be understood that when the diameter of the C-shaped structure is larger, this part clamps the aluminum tube with a larger diameter, and when the C-shaped structure is smaller, this part clamps the aluminum tube with a smaller diameter, which is suitable for aluminum tubes with variable diameter 301, but is not limited to this. This solution realizes the clamping of aluminum tubes with variable diameters.

[0046] like Figure 4 As shown, in other embodiments, the aluminum tube is any one or a combination of a reduced diameter aluminum tube 301, an aluminum tube with a welded joint 302, an aluminum tube with a reduced diameter joint 303, and an aluminum tube with a shorter bending section than 304. The required combination of the base and the assembly block is selected according to the aluminum tube 3 under different working conditions.

[0047] like Figure 4 As shown, the utility model also provides a slipform machine, which includes the combined bending slipform in the above embodiment, and also includes: a slipform drive mechanism 4, a clamping die assembly 5 and a round die 6, wherein:

[0048] Sliding form driving machine, 4, the sliding form driving mechanism 4 comprises a slideway, the combined bending sliding form is connected to the slideway, and the sliding form driving mechanism drives the sliding form to move;

[0049] A clamping die assembly 5 is arranged vertically and parallelly with the combined bending slide die, and is used to clamp the aluminum tube 3;

[0050] The circular die 6 is arranged parallel to the clamping die assembly 5, and the aluminum tube 3 passes through between the clamping die assembly 5 and the circular die 6, and the circular die 6 rotates to complete the bending of the aluminum tube 3;

[0051] The combined bending slide mold drives the aluminum tube to be transported forward, the clamping mold assembly clamps the aluminum tube, and the circular mold rotates to complete the bending of the aluminum tube.

[0052] The bending machine of the utility model can bend aluminum tubes under abnormal working conditions, including aluminum tubes that are reduced-diameter aluminum tubes, aluminum tubes with welded joints, aluminum tubes with reduced-diameter joints, and aluminum tubes with short bending sections. When bending, it is only necessary to replace the combination block or the base according to the working conditions of the aluminum tube, and there is no need to remove the aluminum tubes containing some special-shaped parts from the bending machine and then perform manual bending, thereby improving the applicability of the device.

[0053] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
