Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing, and more specifically to a detachable shaping drum pusher device. Background Technology

[0002] As is well known, the tire blank forming process involves the tire barrel being separated and joined by the shaping drum chuck, which then forms the shape of the tire blank. The position of the shaping drum chuck is controlled by the positioning component. During use, the positioning key in the positioning component is prone to wear. The positioning key and the positioning component are an integral structure. After the positioning key is worn, it is impossible to repair or replace the positioning key individually. Moreover, the positioning component is difficult to disassemble, resulting in high equipment maintenance costs. If the positioning key cannot be replaced in time, it will affect the positional accuracy of the shaping drum chuck. The positional accuracy of the shaping drum chuck ultimately determines the forming accuracy of the tire blank. If the positional accuracy of the shaping drum chuck is poor, it will lead to the production of defective products such as skewed tire blank forming and visible bead lines. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a detachable shaping drum pusher sleeve device, which solves the problems of difficult disassembly of the shaping drum chuck positioning component and high equipment maintenance costs.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a detachable shaping drum pusher device, which is equipped with a main unit box. The main unit box has a cylindrical shaping drum main shaft fixed on it. Two shaping drum chucks are fitted on the shaping drum main shaft. Inside the shaping drum main shaft is a shaping drum screw. The end of the shaping drum screw is connected to the output shaft of the motor in the main unit box. One side of the shaping drum screw has a left-hand thread and the other side has a right-hand thread. Positioning components are provided on the threads on both sides. The positioning components have shaping drum screw nuts. The shaping drum screw nuts are connected to the positioning sleeves. The lower column of the positioning key cooperates with the groove on the positioning sleeve. The positioning key fixing bolt is connected to the positioning sleeve. The upper column of the positioning key is fixedly connected to the shaping drum chucks. The cylindrical wall of the shaping drum main shaft is machined with an upper guide groove and a lower guide groove. The upper column and the lower column of the positioning key are slidably engaged with the upper guide groove and the lower guide groove, respectively.

[0005] The positioning component is located inside the cylindrical shaping drum spindle.

[0006] The aforementioned shaped drum lead screw nut is connected to the positioning sleeve via a lead screw nut fixing bolt.

[0007] The beneficial effects of this utility model are that the upper column of the positioning key is fixedly connected to the shaping drum chuck through the positioning component cover, the lower column of the positioning key cooperates with the positioning sleeve, and the positioning key fixing bolt fixes the positioning key bolt hole to the positioning sleeve. The connection and fixing structure is reliable, the equipment is easy to maintain, the equipment maintenance cost is low, and the positioning accuracy of the shaping drum chuck can be guaranteed.

[0016] In the figure, this utility model includes a main unit housing 1, on which a cylindrical shaping drum main shaft 2 is fixed. Two shaping drum chucks 3 are mounted on the shaping drum main shaft 2. Inside the shaping drum main shaft 2 is a shaping drum lead screw 6. The end of the shaping drum lead screw 6 is connected to the output shaft of a motor inside the main unit housing 1. One side of the shaping drum lead screw 6 has a left-hand thread, and the other side has a right-hand thread. Positioning components 5 are provided on the threads on both sides. The positioning components 5 are located inside the cylindrical shaping drum main shaft 2. The positioning components 5 have a shaping drum lead screw nut 5-1. The shaping drum lead screw nut 5-1 is connected to the positioning sleeve 5-2 through a lead screw nut fixing bolt 5-4. The positioning sleeve 5-2 has a groove in the middle part, and a positioning key 5-3 has a positioning... The positioning key has a lower column 5-3-1, a positioning key bolt hole 5-3-2, and an upper column 5-3-3. The lower column 5-3-1 of the positioning key 5-3 engages with the groove on the positioning sleeve 5-2. The positioning key bolt hole 5-3-2 is connected to the positioning sleeve 5-2 by a positioning key fixing bolt 5-5. The positioning component cover 7 and the shaping drum chuck 3 have bolt holes. The upper column 5-3-3 of the positioning key 5-3 can be fixedly connected to the shaping drum chuck 3 by bolts through the positioning component cover 7. The cylindrical wall of the shaping drum spindle 2 is machined with an upper guide groove 8 and a lower guide groove 9. The upper column 5-3-3 and the lower column 5-3-1 of the positioning key are slidably engaged with the upper guide groove 8 and the lower guide groove 9, respectively.

[0017] In use, the tire tube is placed between two shaping drum chucks 3. The motor inside the main housing 1 rotates, driving the shaping drum screw 6 inside the shaping drum main shaft 2 to rotate. The rotation of the shaping drum screw 6 synchronously drives the shaping drum screw nut 5-1 to move inward. Since the positioning component 5 is fixedly connected to the shaping drum screw nut 5-1, and the positioning component 5 is fixedly connected to the shaping drum chuck 3 through the positioning component cover 7, it drives the shaping drum chuck 3 to move inward, ultimately shaping the tire tube into the shape of the tire blank 4. During use, if the positioning key 5-3 on the positioning component 5 wears and affects the positioning accuracy of the shaping drum chuck 3, the positioning key fixing bolt 5-5 can be removed and the positioning key 5-3 can be directly replaced, making the maintenance process simple and quick.
