Detailed Description
The core of the invention is to provide the tire forming and laminating drum, the product specification adaptability of the tire forming and laminating drum is better, and the production efficiency and the processing and forming quality of tire products are higher.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 and 2, fig. 1 is a front view of a tire building drum structure according to an embodiment of the present invention; figure 2 is a schematic axial view of the grooved drum section of figure 1.
In a specific embodiment, the tire forming and laminating drum provided by the invention comprises a drum body 11, a groove cylinder 12 and an edge ring base 13 which are coaxially and sequentially arranged along an axial direction, wherein a groove 14 matched with a tire is arranged on the outer wall of the groove cylinder 12 along the circumferential direction of the groove cylinder, and the groove cylinder 12 is detachably connected with the drum body 11.
Because the tire shaping laminating drum has adopted recess section of thick bamboo 12 and drum body 11 detachable connections's structure for if need the side wall reinforcement of the different size specifications of adaptation glue in the actual production operation, only need to lift off recess section of thick bamboo 12 by drum body 11, and select the recess section of thick bamboo 12 and drum body 11 reassembling connection with the side wall reinforcement glue size looks adaptation, can satisfy the tire production processing demand of corresponding size specification, and this recess section of thick bamboo 12 changes the dress operation degree of difficulty less, and dismouting process simple accurate has effectively guaranteed the whole production efficiency of tire shaping laminating drum changes corresponding recess section of thick bamboo 12 according to different specification tire production needs simultaneously, is showing the tire product suitability that has improved tire shaping laminating drum, and makes its product processing shaping quality corresponding improvement.
Further, the groove cylinder 12 includes a bead lock block 121 and a groove base 122 coaxially disposed, the groove 14 is located on an outer wall of the groove base 122, the drum body 11, the bead lock block 121, the groove base 122 and the edge ring base 13 are sequentially disposed along an axial direction, and the groove base is detachably connected to the bead lock block. Further differentiate into the split type structure of compriseing bead locking piece 121 and recess base 122 with groove barrel 12 for in actual operation, only need to carry out the structure matching to different size specification side wall reinforcement glues to recess base 122 dismouting change alone, thereby further improved the product specification suitability and the production efficiency of tire shaping laminating drum, and make its product machine-shaping quality can further improve.
Specifically, the groove drum 12 is detachably provided on the drum body 11 through a connection member 123. This connecting piece 123 can further reduce the dismouting of a groove section of thick bamboo 12 and drum body 11 and be connected the degree of difficulty to avoid the influence of dismouting connection structure to its subassembly major structure between a groove section of thick bamboo 12 and drum body 11, guarantee joint strength and equipment operational reliability.
More specifically, the connecting member 123 is an elongated bolt, and the axis of the elongated bolt is parallel to the axis of the groove cylinder 12. The lengthened bolt is simple and reliable in structure, simple and easy to disassemble and assemble, and capable of effectively improving disassembling and assembling efficiency while ensuring assembling strength. Of course, the assembly form between the drum body 11 and the groove cylinder 12 is not limited to the bolt connection shown in the figure, and other assembly forms with disassembly and assembly capabilities, such as direct screw assembly or snap-fit assembly through a buckle and a clamping groove, may also be adopted, as long as the actual use requirements of the tire building and fitting drum can be satisfied in principle.
It should be further noted that, when the groove cylinder 12 is a split structure composed of the bead lock block 121 and the groove base 122 as shown in the figure, the extension bolt sequentially penetrates through the groove base 122 and the bead lock block 121 along the axial direction and is assembled with the drum body 11 by screw threads, when the groove base 122 is replaced, the groove base 122 can be detached by unscrewing the extension bolt, and after the groove base 122 of a corresponding specification is replaced, the assembly can be completed by screwing the extension bolt again.
On the other hand, the number of the extension bolts is even, and the extension bolts are uniformly distributed along the circumferential direction of the groove cylinder 12. The circumferential uniform distribution structure can effectively ensure the assembly strength between the drum body 11 and the groove drum 12, and the stress distribution of the assembly structure is more uniform.
In addition, the number of the extension bolts in practical application may be preferably 4, and the number of the extension bolts can be flexibly adjusted by a worker according to practical requirements, and in principle, the extension bolts may be any bolts as long as the bolts can ensure reliable assembly between the groove cylinder 12 and the drum body 11 and meet practical use requirements of the tire building and fitting drum.
In addition, particularly in actual production work, the width of the groove 14 in the axial direction of the groove barrel 12 (i.e., L shown in fig. 1) is 60mm to 120mm, and the depth of the groove 14 in the radial direction of the groove barrel 12 (i.e., H shown in fig. 1) is 5mm to 8 mm. This size range can guarantee that recess 14 adapts to the size of the side wall reinforcement of the overwhelming majority and glues to satisfy the machine-shaping needs of the tire of the overwhelming majority specification. Of course, the worker can also flexibly adjust the dimension of the groove 14 according to the actual production requirement, and the adjustment range of the dimension of the groove 14 is not limited to the above, and in principle, the adjustment range can be any range as long as the adjustment range can meet the actual tire processing and forming requirement of the tire forming and laminating drum.
In summary, the tire forming and laminating drum provided by the invention adopts the structure that the groove cylinders are detachably connected with the drum body, so that in actual production operation, if the tire side reinforcing glue with different sizes and specifications needs to be adapted, the groove cylinders are only required to be dismounted from the drum body, and the groove cylinders with the sizes matched with the sizes of the tire side reinforcing glue are selected to be reassembled and connected with the drum body, and the tire production and processing requirements with corresponding sizes and specifications can be met.
The tire building drum according to the present invention is described in detail above. The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the method and its core concepts.
