Description

Technical Field

[0001] This invention relates to the field of tire manufacturing equipment, and more specifically to a method for manufacturing high-performance tires. Background Technology

[0002] To improve the uniformity and dynamic balance of vulcanized tires, existing technology has invented a device for manufacturing tires. This device consists of alternating large and small modules arranged circumferentially, and the modules can move radially. When the modules move radially inward, the large and small modules close up to facilitate the loading and unloading of the tires. When the modules move radially outward, the large and small modules open up, forming the inner cavity shape of the tire and expanding the tire blank.

[0003] To avoid interference between the large and small modules during the opening process, the large module always opens to its full position before the small module does. This means that after the large module expands the tire blank, there is a certain period of time before the small module is in place. During this time, the tire blank corresponding to the large module deforms more evenly and experiences less stress due to the support of the module. However, the tire blank corresponding to the small module is stretched during the opening of the large module, resulting in uneven deformation and higher internal stress compared to the tire blank corresponding to the large module. The longer the tire blank remains in this state, the greater the damage to the tire blank, which affects the overall performance of the vulcanized tire. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention provides a method for manufacturing high-performance tires, which reduces the time difference between the opening of different modules, and at the same time reduces the stretching time of the tire blank at the corresponding part of the module without support, thereby reducing the damage to the tire blank during the module opening process and improving the uniformity of the vulcanized tire.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a method for manufacturing high-performance tires, implemented by an apparatus for manufacturing high-performance tires, the apparatus for manufacturing high-performance tires comprising a first module segment and a second module segment arranged circumferentially and forming a complete ring, the first module segment and the second module segment respectively comprising a plurality of first modules and second modules, the plurality of first modules and second modules being alternately arranged.

Detailed Implementation

[0044] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0045] like Figure 1 , Figure 2 As shown, an apparatus for manufacturing high-performance tires includes a first module segment and a second module segment arranged circumferentially and forming a complete ring. A first support guide plate 13 is provided below the first module segment, and a second support guide plate 15 is provided below the second module segment. Both support guide plates are provided with a plurality of guide structures 12 arranged circumferentially at intervals. The guide structures 12 can guide the first module 2 to move radially on the first support guide plate 13 below the first module segment, and the guide structures 12 can guide the second module 1 to move radially on the second support guide plate 15 below the second module segment.

[0046] The system also includes a drive assembly connected to the first and second module segments. The drive assembly can drive the first and second module segments to retract or expand, respectively. A support guide plate below the first module segment is designated as a first support guide plate 13, and a support guide plate below the second module segment is designated as a second support guide plate 15. The second support guide plate 15 includes multiple support portions spaced circumferentially. The second module segment is mounted on the multiple support portions via multiple guide structures 12. The first support guide plate 13 has a placement groove, and the second support guide plate 15 can be embedded within the placement groove.

[0047] The first support guide plate 13 below the first module segment is fixed to the hot plate 16 of the vulcanizing equipment, and the second support guide plate 15 below the second module segment is liftable. The first and second module segments of this invention each include several first modules 2 and second modules 1, with the same number of first modules 2 and second modules 1, preferably 4-8. The dividing seams of adjacent first modules 2 and second modules 1 form an angle with the radial line of the complete ring, resulting in the inner arc length of the first module 2 being less than the outer arc length, and the inner arc length of the second module 1 being greater than the outer arc length. The first modules 2 and 1 are arranged circumferentially in an alternating pattern to form a ring, the outer wall of which is used to mold the inner surface of the tire. By utilizing the specific structure of the first modules 2 and second modules 1, and with the aid of program logic control, the first modules 2 and second modules 1 are radially opened together into position, minimizing the damage caused to the tire blank 14 by module movement and improving the overall performance of the vulcanized tire.

[0048] The driving component of this invention specifically includes a central lifting mechanism. An opening in the center of the hot plate 16 of the vulcanizing equipment allows the central lifting mechanism to rise and fall. The central lifting mechanism is hinged to the first module segment and the second module segment via connecting rods to drive the first and second module segments to retract or expand. The central lifting mechanism includes a first lifting rod 7, on which a first upper ring 4 is fixed. The outer side of the first upper ring 4 is hinged to the inner side of each second module 1 via multiple first connecting rods 3, i.e., one end of the first connecting rod 3 is hinged to the first upper ring 4, and the other end of the first connecting rod 3 is hinged to the inner side of the corresponding second module 1. It also includes a second lifting sleeve 8, which is sleeved on the first lifting rod 7. A second upper ring 6 is fixedly mounted on the lowering sleeve 8. The outer side of the second upper ring 6 is hinged to the inner side of each first module 2 via multiple second connecting rods 5. That is, one end of the second connecting rod 5 is hinged to the second upper ring 6, and the other end of the second connecting rod 5 is hinged to the inner side of the corresponding first module 2. It also includes a third lifting ring 9, which is sleeved on the outer side of the second lifting sleeve 8. The third lifting ring 9 is connected to the bottom of the second support guide plate 15 below the second module section. The third lifting ring 9 can drive the second module section to rise and fall through the second support guide plate 15 below the second module section. The third lifting ring 9 is provided with multiple circumferentially spaced clearance grooves, and the corresponding second connecting rods 5 can pass through the clearance grooves to achieve smooth opening and closing. The central lifting mechanism also includes several driving devices, such as hydraulic cylinders, for driving the first lifting rod 7, the second lifting sleeve 8, and the third lifting ring 9 to rise and fall.

[0049] The second support guide plate 15 includes a plurality of support portions arranged circumferentially. The second module segment is arranged on the plurality of support portions by a plurality of guide structures 12. The first support guide plate 13 is preferably provided with a placement groove, and the second support guide plate 15 can be embedded in the placement groove.

[0050] The first module segment also includes a first module support base 11, which is detachably connected to the inside of the first module 2 and is connected to the drive component; the second module segment also includes a second module support base 10, which is detachably connected to the inside of the second module 1 and is connected to the drive component. The guide structure 12 of the present invention is configured as a guide rail or slide groove on the support guide plate. The bottom of the first module support base 11 and the second support base 10 are both provided with sliders to connect to the corresponding guide rails or slide grooves to ensure the sliding accuracy of the first module 2 and the second module 1.

[0051] A method for manufacturing high-performance tires includes the following steps:

[0052] (1) such as Figure 3 , Figure 4As shown, after the central lifting mechanism drives the second module section to retract and rise, it drives the first module section to retract and place the tire blank 14. Both the second module section and the first module section are in the retracted state. The radial retraction distance between the first module section and the second module section is L. The second module section is located above the first module section.

[0053] (2) such as Figures 5 to 7 As shown, the first module segment is radially spread out by a distance L1. At this time, the first module segment does not contact the blank 14. The radial distance between the first module segment and the blank 14 is D1, D1+L1=L. D1 is preferably ≥5mm, and more preferably 10-50mm.

[0054] (3) such as Figure 8 , Figure 9 As shown, the second module segment descends axially along with the supporting guide plate below the second module segment, and the descent height is H, until it is level with the first module segment. Before this, after the first module segment is radially expanded in step (2), the distance between adjacent first modules 2 must be greater than the size of the second module 1.

[0055] (4) such as Figure 10 , Figure 11 As shown, the radial expansion distance of the second module segment is L2. At this time, the second module 1 is in contact with the dividing seam of the first module 2. The radial distance between the second module segment and the blank 14 is D2, where D2 > D1.

[0056] (5) such as Figure 12 As shown, the first module segment and the second module segment are radially expanded simultaneously. The expansion speed of the first module segment is less than that of the second module segment. The first module segment and the second module segment are required to contact the tire blank 14 simultaneously.

[0057] In this invention, the first and second module segments open radially and simultaneously into place, minimizing damage to the tire blank caused by module movement and improving the overall performance of the vulcanized tire, such as uniformity and dynamic balance. Furthermore, the time required for the first module segment to open radially a distance L1 is T1; the time required for the second module segment to descend to be flush with the first module segment is T2; the time required for the second module segment to open radially a distance L2 is T3; the time required for the first and second module segments to open radially simultaneously is T4; and the time required for mold closing is T = T1 + T2 + T3 + T4. Compared to traditional methods, this invention, due to the simultaneous action in the final stage, has a relatively shorter time consumption, thus improving production efficiency.

[0058] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the invention. Furthermore, it should be understood that after reading the technical description of this invention, those skilled in the art can make various alterations, modifications, and / or variations to the invention, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
