Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing technology, specifically a six-drum all-steel engineering radial tire two-stage forming machine. Background Technology

[0002] The forming machine is a crucial piece of equipment in the production of all-steel radial engineering tires. Traditional two-stage forming machines for all-steel radial engineering tires mostly employ a four-drum layout consisting of a bonding drum, a forming drum, a belt drum, and a sizing drum. The tire blank undergoes corresponding processes in these drums to become a green tire. Because the forming times for each drum differ—the forming and sizing drum processes are longer than those for the tire body drum and belt drum—the traditional four-drum layout results in some equipment being idle, impacting production efficiency.

[0003] To avoid equipment downtime while maintaining production capacity, the applicant previously applied for a patent for a "two-stage five-drum forming machine for all-steel giant radial tires" (application number CN201420836374.2), which includes a tire carcass bonding device, two forming devices, a belt layer bonding device, a shaping device, and supporting facilities for each device, as well as a transfer device. The two forming devices and the belt layer bonding device, along with their respective supporting facilities, are located on one side of the transfer device, while the tire carcass bonding device and the shaping device, along with their respective supporting facilities, are located on the other side of the transfer device. The belt layer bonding device includes a belt layer bonding drum and a belt layer transfer ring mounted on the belt layer bonding bed via a guide rail mechanism perpendicular to the center line of the transfer device.

[0004] The earlier application reduced downtime for the carcass drum and belt drum by adding a molding device. However, with improvements in processes and equipment, the efficiency of the carcass drum and belt drum has increased, while the downtime for the shaping drum has increased, making the five-drum molding machine unable to meet production demands. Furthermore, in the earlier application, the belt layer transfer ring slides along a guide rail mechanism perpendicular to the center line of the transfer device. The belt layer bonding device and shaping device are installed on both sides of the guide rail mechanism. The belt layer transfer ring can only be matched with one set of belt layer bonding and shaping devices for operation, which has significant limitations.

[0005] Based on the above issues, further improvements are needed to the previously applied-for all-steel giant radial tire two-stage five-drum forming machine to reduce equipment downtime and improve production efficiency. Utility Model Content

[0006] This utility model provides a six-drum all-steel engineering radial tire secondary forming machine, which can improve the time allocation of each drum process, make each process seamless, reduce equipment downtime, and improve production efficiency.

[0053] The forming drum-shaped feeding mechanism 35 feeds the material, while the mechanical front and back wrapping mechanism wraps the steel cord fabric in both directions. The pressure rollers 36 behind the forming drum press and vent the air. After the forming drum 32 finishes its work, the tire carcass is transported to the belt transfer ring 8, clamped, and then returned. Both forming devices 3 operate simultaneously, alternately outputting the formed tire carcass.

[0054] 3. The belt transfer ring 8 moves to the receiving position of the target shaping drum 52, the shaping drum 52 moves to the middle of the belt transfer ring 8, the belt transfer ring 8 releases the molding body cylinder to the shaping drum 52, and the shaping drum 52 retracts to wait for the belt cylinder.

[0055] 4. The belt drum feeding mechanism 44 feeds the belt drum 42 to produce the belt bundle. After the belt bundle is produced, it moves with the belt drum 42 to the center of the belt transfer ring 8. After the belt transfer ring 8 clamps it, the belt drum 42 returns. The belt transfer ring 8 moves the belt bundle to the receiving position of the target shaping drum 52.
