In actual on-site production, there are many specifications and models of steel wire rings ranging from 28 inches to 38 inches used to produce tire blanks. Conventionally, each steel wire ring specification and model is equipped with a pair of bead rings. Changing to a different steel wire ring model requires disassembling and replacing the bead rings. Due to the influence of the forming drum position, the replacement process is very inconvenient. Summary of the Invention

[0022] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit the scope of this application. Unless otherwise specified, the methods used in this utility model are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0023] Depend on Figure 1 As shown, this utility model provides an outer buckle forming device. The outer buckle forming device includes a base 5, a column, a linear reciprocating device 6, and a buckle disc 1. The column is installed on the base 5, and the linear reciprocating device 6 is installed horizontally on the column. The telescopic rod of the linear reciprocating device 6 is connected to the buckle disc 1. The column includes a rotating wall column 7, a rotating arm spindle 8, and a rotating arm sleeve 9. The rotating arm spindle 8 is connected to the rotating wall column 7, and the rotating arm sleeve 9 is coaxially sleeved and rotatably connected to the rotating arm spindle 8. The linear reciprocating device 6 is installed horizontally on the rotating arm sleeve 9.

[0024] The working principle of this utility model is as follows: Figure 2 As shown, when a new steel wire ring model needs to be replaced according to the production plan, the operator pushes the linear reciprocating device 6. The linear reciprocating device 6, together with the rotating arm sleeve 9, rotates around the rotating arm spindle 8, so that the buckle plate 1 and the forming drum 16 are offset by a certain angle, providing sufficient space for replacing the new buckle plate 1, and also facilitating the use of large disassembly fixtures. The replacement process is convenient and quick, and completely avoids the influence of the position of the forming drum 16 in the existing technology.

[0025] In some embodiments, preferably, the bottom end of the rotating arm spindle 8 is connected to the rotating wall column 7, and the top end of the rotating arm spindle 8 passes upward through the rotating arm sleeve 9. The rotating arm sleeve 9 is rotatably connected to the rotating arm spindle 8 through a rotating arm bearing. The rotating arm bearing has advantages such as high load capacity, low friction, wear resistance, and corrosion resistance.

[0026] In some embodiments, the linear reciprocating device 6 is preferably a cylinder, which has a simple structure and high reliability. In the field, an electric cylinder or other linear reciprocating device 6 can also be used instead of a cylinder.

[0027] In some embodiments, by Figure 1 As shown, preferably, the rotating arm mandrel 8 passes upward through the rotating arm sleeve 9 and extends out to be threadedly connected to the rotating arm shaft nut 11. After replacing the retaining ring disc 1, rotate the linear reciprocating device 6 back to its original position so that the retaining ring disc 1 is facing the forming drum 16. Then install the rotating arm shaft nut 11 to fix the rotating arm sleeve 9 onto the rotating arm mandrel 8. This ensures that during the subsequent forming process, the wire ring is wrapped on the retaining ring disc 1. Under the action of the linear reciprocating device 6, the wire ring is fastened onto the tire carcass cord layer that is wrapped on the forming drum 16 through the retaining ring disc 1, thus completing the tire bead wrapping of the cord cylinder.

[0028] In some embodiments, by Figure 1 As shown, the outer buckle forming device is preferably equipped with a transverse support 12, which is horizontally mounted on the rotating arm sleeve 9. The linear reciprocating device 6 is mounted on the transverse support 12, making the extension and retraction of the buckle disc 1 driven by the linear reciprocating device 6 more stable and reliable. As a further preferred embodiment, the linear reciprocating device 6 is detachably mounted on the transverse support 12 via the mounting base 13, making the installation and disassembly of the linear reciprocating device 6 more convenient and quick, and facilitating the replacement and maintenance of the linear reciprocating device 6.

[0029] In some embodiments, by Figure 1 As shown, the linear reciprocating device 6 is preferably also equipped with a guide rod 14. One end of the guide rod 14 is connected to the end of the telescopic rod near the linear reciprocating device 6 via a fixing plate 15, and the other end of the guide rod 14 passes through the mounting base 13 and extends out, with the two slidably connected. The guide rod 14 is parallel to the telescopic rod of the linear reciprocating device 6. During the process of the linear reciprocating device 6 pushing the buckle disc 1 by the extension or retraction of the telescopic rod, the guide rod 14 plays a guiding role, making the process more stable and reliable.

[0030] In some embodiments, by Figure 3 , Figure 4As shown, the outer buckle forming device preferably also includes a buckle ring 3, which has a groove 4; the buckle disc 1 has a protrusion 2, and the groove 4 and the protrusion 2 are detachably and fixedly connected. When replacing buckle discs 1 of different sizes, only the old buckle ring 3 needs to be removed and the new buckle disc 1 installed, which is time-saving, labor-saving, convenient and quick. Moreover, the buckle disc 1 is small, saving space and improving disassembly and replacement efficiency. The detachable design of the buckle ring 3 and the buckle disc 1 reduces the frequent replacement of the buckle disc 1 and the cylinder shaft head, making it easier to install and use the buckle disc 1. This solves the technical problems of existing technologies where replacing a steel wire ring model requires disassembling and replacing the integrated buckle disc 1, which consumes a lot of materials, has high processing costs, occupies a lot of space, and has low disassembly and replacement efficiency. As a further preferred embodiment, the groove 4 and the protrusion 2 are detachably and fixedly connected by bolts. The bolt thread connection makes disassembly and installation more convenient and quick.

[0031] In some embodiments, by Figure 1 As shown, the outer buckle ring forming device is preferably equipped with a rotating arm lifting adjustment device. The rotating arm lifting adjustment device is equipped with a lifting sleeve 10. An adjusting nut is installed inside the lifting sleeve 10. The column body of the rotating wall column 7 is provided with a thread that matches the adjusting nut, and the length of the thread is greater than the thickness of the adjusting nut. The lifting sleeve 10 is threadedly connected to the rotating wall column 7 through the adjusting nut. The rotating arm sleeve 9 is tightly installed on the lifting sleeve 10. Along the axial direction of the rotating arm spindle 8, the rotating arm sleeve 9 is slidably connected to the rotating arm spindle 8. In actual production, when the buckle disc 1 and the forming drum 16 cannot be aligned and are misaligned, the operator rotates the lifting sleeve 10. The adjusting nut fixed inside the lifting sleeve 10 rotates on the thread of the column body located on the rotating wall column 7, so that the lifting sleeve 10 moves up and down relative to the column body of the rotating wall column 7. During the up and down adjustment of the lifting sleeve 10, the rotating arm sleeve 9 rises or falls along the axial direction of the rotating arm spindle 8, that is, the buckle disc 1, the linear reciprocating device 6, and the rotating arm sleeve 9 rise or fall as a whole, so that the buckle disc 1 and the forming drum 16 are aligned, ensuring the smooth progress of the subsequent forming process.
