DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0035] In the description of the present application, it should be understood that the terms "center", "upper", "lower", "top", "bottom", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The terms "inner", "outer", "radial", "circumferential", etc. are all relative to the side ring pair, the inner part close to the side ring pair is "inner", and the outer part close to the side ring pair is "outer".

[0036] The terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Thus, a feature defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features.

[0037] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0038] like Figure 1-6 As shown, the present application provides a forming drum cross side ring pair (hereinafter referred to as the side ring pair), which can be installed on the forming drum and is a cover plate type forming drum cross side ring pair. The side ring pair includes two side rings arranged opposite to each other, namely a first side ring 1 and a second side ring 2; wherein:

[0039] like Figure 1 and Figure 2 As shown, the first side ring 1 has an annular first mounting ring 101 and a plurality of first cross teeth 102; the first mounting ring 101 is used to mount the first side ring 1 on the first side of the forming drum (not shown in the figure); the first cross teeth 102 are evenly distributed along the first mounting ring 101 and are perpendicular to the radial direction of the first mounting ring 101.

[0040] like Figure 3-5 As shown, the second side ring 2 has an annular second mounting ring 201 and a plurality of second cross teeth 202; the second mounting ring 201 is used to mount the second side ring 2 on a second side (not shown in the figure) opposite to the first side of the forming drum; the second cross teeth 202 are evenly distributed along the second mounting ring 201 and are perpendicular to the radial direction of the second mounting ring 201.

[0041] When the first side ring 1 and the second side ring 2 are matched, Figure 6 As shown, the second cross teeth 202 can be accommodated between adjacent first cross teeth 102 , and the first cross teeth 102 can be accommodated between adjacent second cross teeth 202 , so that the first cross teeth 102 and the second cross teeth 202 are alternately arranged.

[0042] In addition, if Figure 1-2 As shown, the first side ring 1 is further provided with a first cover plate 103, which is distributed along the first mounting ring 101 to replace part of the first cross teeth 102. Figure 3-5 As shown, the second side ring 2 is also provided with a second cover plate 203, which is distributed along the second mounting ring 201 to replace part of the second cross teeth 202. In the circumferential direction, the width of the first cover plate 103 is greater than the width of each first cross tooth 102; the width of the second cover plate 203 is greater than the width of each second cross tooth 202. The widths of the first cover plate 103 and the second cover plate 203 are roughly equal; when the first side ring 1 and the second side ring 2 are matched, the first cover plate 103 and the second cover plate 203 are matched along the radial direction.

[0043] Specifically, the width of each cross tooth 102, 202 is approximately 4-7 mm, such as 5 mm, 6 mm, etc., and the width of the first cover plate 103 and the second cover plate 203 are approximately 44-81 mm, such as 50 mm, 55 mm, 60 mm, 65 mm, 70 mm, 75 mm, 80 mm, etc. Or the width of each cover plate is 11-13 times the width of the cross tooth, such as 11 times, 12 times, 13 times, etc.; such a setting makes the tread joint completely on the cover plate, which is convenient for laser detection and identification of the joint located at the cover plate, and solves the laser joint detection problem caused by only setting the cross teeth.

[0044] In radial direction, the first cover plate 103 is on the outside, and the second cover plate 203 is on the inside. The first cover plate 103 can be made of a plate structure, which is relatively thin, which is conducive to reducing the overall weight of the side ring pair. Plate-structured retaining edges 104 can also be set on both sides of the first cover plate 103 to facilitate accommodating the second cover plate 203. Figure 4 As shown, the second cover plate 203 is radially inward, so that a reserved space 204 for accommodating the first cover plate 103 is formed on the outside, so that the two are matched with each other. The thickness (along the radial direction) of the first cover plate 103 and the second cover plate 203 after matching is roughly equal to the thickness of each cross tooth. In addition, the length of the first cross tooth 102, the length of the second cross tooth 202, the length of the first cover plate 103 and the length of the second cover plate 203 are roughly equal. It can be seen from the figure that the length of the cross teeth extends along the axial direction of the mounting ring, the width of the cross teeth extends along the circumferential direction of the mounting ring, and the thickness of the cross teeth extends along the radial direction of the mounting ring.

[0045] In one embodiment, if Figure 2 and Figure 4As shown, the first cross teeth 102 are located on the outside of the first mounting ring 101, and the second cross teeth 202 are located on the outside of the second mounting ring 201; thereby more accommodation space is formed between adjacent cross teeth on the outside of the mounting ring.

[0046] In a more specific embodiment, the first cross teeth 102 are fixedly mounted on the outer wall of the first mounting ring 101, and the second cross teeth 202 are fixedly mounted on the outer wall of the second mounting ring 201. For example, the cross teeth can be welded to the mounting ring to achieve this fixation, or 3D printing technology can be used to form them in one piece during printing.

[0047] In another specific embodiment, the bottoms of the first cross teeth 102 share a first fixing ring 105, which is connected to the first mounting ring 101 and is a plate structure, much thinner than the first mounting ring 101; the bottoms of the second cross teeth 202 share a second fixing ring 205, which is connected to the second mounting ring 201 and is a plate structure, much thinner than the second mounting ring 201. By setting the fixing ring, each cross tooth can be well installed and fixed. Since the fixing ring is a plate structure, which is much thinner than the mounting ring, more accommodation space can be formed between adjacent cross teeth.

[0048] Assume that the length of a side ring is 20cm, the mounting ring is 5cm, and the fixed ring is 1cm. Scenario 1: When the cross teeth are installed on the mounting ring, the length of the cross teeth is 15cm, and the total length of the side rings when fully matched is 25cm (20+5), and the total length when fully separated is 40cm (20+20). Scenario 2: When the cross teeth are installed on the fixed ring, the length of the cross teeth is 19cm, and the total length of the side rings when fully matched is 21cm (20+1), and the total length when fully separated is 40cm (20+20). Scenario 3: When the cross teeth are welded to the outside of the mounting ring, the length of the cross teeth is 20cm, and the total length of the side rings when fully matched is 20cm (20+0), and the total length when fully separated is 40cm (20+20). It can be seen that through such a setting, when the total length remains unchanged when separated, the length of the side ring pair provided by the present application can be reduced when mated; conversely, when the length remains unchanged when mated, the length of the side ring pair provided by the present application can reach the maximum when separated; thus, it can be used for ultra-flat tire processing and has the advantage of a large telescopic spacing.

[0049] The mounting ring and the fixing ring can also be an integrally formed structure, and the fixing ring can be regarded as a partial extension of the mounting ring. The mounting ring must be thick enough to have sufficient supporting strength when installed on the forming drum. The thickness of the mounting ring is 1.5-2.5 times that of the fixing ring, such as 1.8 times, 2 times, 2.2 times, etc.

[0050] A chamfered first reinforcing rib 106 is provided between the first fixing ring 105, the first mounting ring 101 and the adjacent first cross teeth 102; a chamfered second reinforcing rib 206 is provided between the second fixing ring 205, the second mounting ring 201 and the adjacent second cross teeth 202; each reinforcing rib forms a multi-directional strength reinforcement effect between the components, greatly increasing the strength of the side ring. Correspondingly, the free ends of each cross tooth 102, 202 are chamfered on the inside; when the first side ring 1 and the second side ring 2 are matched, the chamfer of the first cross tooth 102 contacts the second reinforcing rib 206 of the second side ring 2; the chamfer of the second cross tooth 202 contacts the first reinforcing rib 106 of the first side ring 1. The chamfering of the free end of the cross teeth facilitates the matching of the first side ring and the second side ring, and is not easy to get stuck to each other. In addition, the above arrangement will not affect the crossing depth of the cross teeth while increasing the strength of the side ring.

[0051] Install the first side ring 1 and the second side ring 2 on the equipment relatively and adjust the cover plate, let the laser shine on it, and stretch it back and forth to check the matching gap. The side ring pair of this application is processed by 3D printing technology; check the cross side rings and measure and confirm their dimensions; after confirmation, put the machine into trial operation and test the produced tire embryos; the finished tire embryos have no abnormalities and meet the design expectations.

[0052] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0053] The above embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present application can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present application, which should be included in the scope of the technical solution requested for protection in the present application.
