Description

Technical Field

[0001] This utility model relates to the field of tire forming drum disassembly tooling technology, specifically a tire forming drum disassembly tooling. Background Technology

[0002] The tire forming drum is a core piece of equipment in the tire manufacturing process, mainly used to precisely bond and shape multiple layers of rubber cord, steel wire, and other materials into a tire blank. Disassembling the tire forming drum requires the use of various equipment.

[0003] Current technologies have the following shortcomings: The dismantling of tire molding drums currently relies primarily on two methods: large mechanical hoisting equipment is used for overall handling and dismantling of heavy components, while manual operation is responsible for more delicate dismantling tasks. Taking drum tile removal as an example, workers typically use traditional pry bars to complete this process. While these pry bars have the advantages of simple structure and reliable operation, their functionality is significantly limited—they are only suitable for prying off the drum tile. When facing the dismantling needs of other components of the molding drum, such as the delamination of the outer rubber layer or the cleaning of adhering adhesive residue, existing pry bars are inadequate, requiring the use of specialized tools such as scrapers and chisels. This results in the need for a large number of tools for dismantling the molding drum. Utility Model Content

[0004] In view of the shortcomings of the single function of the existing technology, this utility model provides a tire forming drum disassembly tool, which solves the problem of low efficiency caused by the need to prepare a large number of tools in the current disassembly process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tire forming drum disassembly tool, comprising a lever arm and a pry head for prying a single drum tile, characterized in that: an integrated connector for quickly disassembling and assembling different functional components is provided at the end of the lever arm, two linkage half gears are rotatably arranged inside the integrated connector, and a right-angle locking block is provided on the outer side of the linkage half gears.

[0006] A plug plate for inserting an integrated connector is welded to the side end of the pry head, and toothed racks are provided on both sides of the plug plate.

[0007] The side end of the insert plate is provided with an anti-disengagement rod for engaging with the groove of the insert plate to clamp the right-angle locking block.

[0008] A screw for controlling the position of the anti-detachment rod is provided on the side end of the anti-detachment rod.

[0009] As a preferred embodiment of this utility model, the anti-detachment rod is sleeved on the end of the screw, and a bearing ring is provided at the connection to prevent the anti-detachment rod from rotating.

[0010] As a preferred technical solution of this utility model, the other end of the screw is inserted into the pry head through a threaded connection, and an adjusting gear ring is fitted on the outside of the screw to facilitate manual rotation of the screw.

[0011] As a preferred technical solution of this utility model, a strip-shaped through groove is opened on the inner side of the lever arm, and a connecting block is rotatably set at its side end.

[0012] As a preferred embodiment of this utility model, the side end of the connecting block is detachably fitted with an auxiliary support plate for providing a fulcrum via bolts.

[0013] As a preferred embodiment of this utility model, an insert rod is rotatably mounted inside the auxiliary support plate via a damping ring.

[0014] As a preferred embodiment of this utility model, a telescopic lever is provided on the other side of the auxiliary support plate, and a center block that engages with the telescopic lever is provided on the inner side of the lever arm.

[0015] Compared with the prior art, this utility model provides a tire forming drum disassembly tool, which has the following beneficial effects:

[0016] A tire forming drum disassembly fixture involves inserting a pry bar through an insert plate into an integrated connector. A rack drives a linkage half-gear to rotate a right-angle locking block 90° until the right-angle locking block is inserted into a groove on the side of the insert plate. At this point, the right-angle locking block is pressed into a gap by an anti-detachment rod, preventing the rack from moving the linkage half-gear and thus locking the pry bar in place. An auxiliary support plate is released by sliding a telescopic lever, allowing it to contact the ground for support. Inserting the insert rod diagonally into the bottom of the tire forming drum further establishes a support frame, at which point the drum can be pried open with the pry bar. When the lever arm is needed for other steps in the forming drum disassembly, the screw can be rotated by adjusting the gear ring with a finger, causing the anti-detachment rod to move to the right. Once the right-angle locking block is no longer under lateral pressure, the operator can simply use the pry bar to detach it from the integrated connector.

[0017] Through the aforementioned setup and process, this structure, compared to traditional pry bar structures, firstly features a standardized integrated connector at the end of the tool body with a quick-release locking mechanism; secondly, it improves the traditional fixed pry bar into a modular interface, capable of serving multiple functional components. This modular design allows operators to quickly change components, achieving multi-purpose functionality without auxiliary tools. It can perform the basic function of prying off roof tiles, and can also switch to dedicated modules to perform derivative operations such as rubber layer peeling and residual adhesive cleaning. Through structural integration and functional expansion, it retains the operational reliability of traditional tools while solving the problem of poor compatibility of a single tool with multiple processes.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 5 In this embodiment: a tire forming drum disassembly tool includes a lever arm 1 and a pry head 2 for prying a single drum tile. An integrated connector 8 for quickly disassembling and assembling different functional components is provided at the end of the lever arm 1. Through modular design, other tools used for tire forming drum disassembly can also be quickly replaced and assembled.

[0026] The end of the pry head 2 is tilted upward at 35° to fit the gap of the drum tile.

[0027] In order to enable the pry head 2 to be installed quickly and stably, two linkage half gears 9 are rotatably arranged inside the integrated connector 8, and a right-angle locking block 10 is set on the outside of the linkage half gears 9. A plug plate 11 for inserting the integrated connector 8 is welded to the side end of the pry head 2, and racks 12 are set on both sides of the plug plate 11.

[0028] When the rack 12 is inserted into the integrated connector 8 along with the insert plate 11, its toothed groove meshes with the linkage half gear 9, causing the linkage half gear 9 to rotate, and the right-angle locking block 10 is inserted into the groove on the side of the insert plate 11 after rotating 90°. An anti-disengagement rod 13 is provided on the side end of the insert plate 11 to engage with the groove of the insert plate 11 and clamp the right-angle locking block 10. The anti-disengagement rod 13 is tightly pressed against the right-angle locking block 10 and locks it in place (e.g., ...). Figure 3 As shown in the figure, the position of the insert plate 11 is fixed at this time.

[0029] In order to enable the pry bar 2 to be quickly disassembled and replaced, a screw 14 is provided on the side of the anti-detachment rod 13 to control the position of the anti-detachment rod 13. When the screw 14 rotates clockwise or counterclockwise, the anti-detachment rod 13 moves to the left or right in sync.

[0030] The anti-detachment rod 13 is sleeved on the end of the screw 14, and a bearing ring is provided at the connection to prevent the anti-detachment rod 13 from rotating. The other end of the screw 14 is inserted into the pry head 2 through a threaded connection. An adjusting gear ring 15 is sleeved on the outside of the screw 14 to facilitate manual rotation of the screw 14.

[0031] To ensure that lever arm 1 has a stable fulcrum when prying the drum tile, a strip-shaped through groove is made on the inner side of lever arm 1, and a connecting block 4 is rotatably installed at its side end. An auxiliary support plate 3 is detachably assembled at the side end of the connecting block 4 by bolts. Figure 4 As shown in the figure, this allows the auxiliary support plate 3 to have rotational support. Inside the auxiliary support plate 3, a plug rod 7 is rotatably installed via a damping ring. The plug rod 7 is inserted into the bottom of the tire forming drum, bringing the auxiliary support plate 3 into contact with the ground, thus creating a four-corner bracket at the lower end of the lever arm 1, thereby providing support for the prying of the lever arm 1.

[0032] A telescopic lever 5 is set on the other side of the auxiliary support plate 3, and a center block 6 is set on the inside of the lever arm 1 to engage with the telescopic lever 5. This allows the auxiliary support plate 3 to be embedded inside the lever arm 1 at any time without affecting the use of other functions.

[0033] In this embodiment, the pry bar 2 is inserted into the integrated connector 8 through the insert plate 11. The rack 12 drives the linkage half gear 9 to rotate the right-angle locking block 10 by 90° until the right-angle locking block 10 is inserted into the groove on the side of the insert plate 11. At this time, the right-angle locking block 10 is pressed into the gap by the anti-disengagement rod 13, so that the rack 12 cannot move the linkage half gear 9, thereby fixing and locking the pry bar 2. The auxiliary support plate 3 is released by sliding the telescopic lever 5 and made to contact the ground for support. The insert rod 7 is inserted obliquely into the bottom of the tire forming drum to further establish the support frame. At this time, the drum tile can be pried open by the pry bar 2.

[0034] When lever arm 1 is needed for other steps in disassembling the molding drum, the screw 14 can be rotated by flicking the adjusting gear ring 15 with your finger, thereby moving the anti-detachment lever 13 to the right. After the right-angle locking block 10 loses its lateral pressure, the operator can simply flick the pry head 2 to disengage it from the integrated connector 8.

[0035] As a replacement for pry bar 2 in this solution, a shovel-shaped replacement head (such as...) Figure 5 (As shown) is more suitable for peeling off the outer rubber layer of the rubber drum.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
