Description

A kind of tire secondary method molding bead apex prebuckling device

Technical field

This utility model belongs to tire preparing technical field, is specifically related to a kind of tire secondary method molding bead apex prebuckling device。

Background technology

The current tire secondary general more application of method forming machine is in heavy load radial tire and large-scale meridian engineered machinery tire, difference because of tire secondary method forming machine Yu single stage building machine, determine that tire building process exists larger difference, the molding of the mainly bead apex molectron that wherein difference is relatively big and moulding process requirement is comparatively difficult, especially for large-scale and giant all-steel meridian engineered machinery tire, bead apex molectron molding laminating difficulty, easily disengage after rolling and choke with resentment, cause the easy residual air of tyre bead portion after tyre vulcanization, and tire is difficult to discovery after X-ray machine detects and chokes with resentment phenomenon, cause tire that early stage tyre bead bulge phenomenon in use occurs。As shown in Figure 1, bead apex molectron includes wire loop 1, it is wound around infantees 2 and triangle rubber 3, cause the main cause of bead apex molectron molding laminating difficulty by: at present the triangle rubber 3 on wire loop is when fitting with carcass 7, triangle rubber is upright triangle rubber, secondary method forming machine needs triangle rubber carries out laminating rolling on assembly drum 6, aerofluxus, upright triangle rubber could be fitted tightly with carcass after carcass curving, owing to meridian engineered machinery tyre triangular glue is relatively large sized, and sizing material hardness is big, it is not easy flexural deformation, therefore laminating process often occurring, triangle rubber is choked with resentment, the problem such as disengagement after roll-in, it is relatively difficult to solve。Because tire cost is high, occur that the tire of tyre bead bulge phenomenon cannot normally use, the loss of enterprise is also very big。

Summary of the invention

The purpose of this utility model is that as solving a kind of tire secondary method molding bead apex prebuckling device of the deficiencies in the prior art offer, promote tyre forming process stability, ensure product tyre bead portion quality stability, reduce potential tyre bead bulge risk, it is ensured that tire entirety serviceability。

The purpose of this utility model realizes with following technical proposals:

A kind of tire secondary method molding bead apex prebuckling device, including rotating workbench, workbench sets prebuckling gripper shoe, and prebuckling gripper shoe shape and molding triangle rubber Internal periphery adapt；Prebuckling device also includes pressure roller molectron, and pressure roller molectron pressure roller direction and molding triangle rubber outline adapt。

Being additionally provided with wire loop gripper shoe on workbench, triangle rubber is applied ointment or plaster with wire loop while prebuckling。

Described workbench two ends are equipped with wire loop gripper shoe, prebuckling gripper shoe。

Described workbench is the roller that can be used for transmitting。

Described roller is the roller on tire secondary method forming machine bead filler thermal-plying locking device, and prebuckling gripper shoe, pressure roller molectron are installed at roller both sides。

Triangle rubber is first carried out prebuckling by the prebuckling device provided by this utility model, then the assembly with carcass is carried out again, shaping efficiency and the technique property passed through of bead apex molectron in forming process can be improved, triangle rubber is easier to laminating, rolling and aerofluxus, and triangle rubber shape and size can keep consistent, deforming little in rolling process, technology stability is good。

Detailed description of the invention

The triangle rubber prebuckling device that this utility model provides, as in figure 2 it is shown, include rotating workbench 8, workbench 8 is driven by motor 10, and workbench 8 sets prebuckling gripper shoe 41, and prebuckling gripper shoe 41 shape and molding triangle rubber Internal periphery adapt；Prebuckling device also includes pressure roller molectron 5, pressure roller molectron 5 pressure roller direction and molding triangle rubber outline adapt, upright triangle rubber is placed in prebuckling gripper shoe 41, workbench 8 rotation process utilize pressure roller molectron 5 by upright triangle rubber brake forming, prebuckling gripper shoe 41 and pressure roller molectron 5 pressure roller direction can be adjusted according to triangle rubber forming shape, the curve that triangle rubber global shape after molding is takeed on after having pasted carcass with secondary method molding drum of forming machine drum adapts, concrete size is according to assembly drum drum shoulder size R, liner and body cord thickness B determine。

As shown in Figure 2, workbench also sets wire loop gripper shoe 91, triangle rubber prebuckling gripper shoe 41 is positioned at workbench 81 end, wire loop gripper shoe 91 is corresponding with triangle rubber size to triangle rubber prebuckling gripper shoe 41 distance, wire loop is placed in gripper shoe side, triangle rubber can realize applying ointment or plaster with the horizontal of wire loop while bending, can be all provided with wire loop gripper shoe and prebuckling gripper shoe in workbench both sides, improves work efficiency。

As shown in Figure 3, directly can carry out triangle rubber prebuckling device on existing tire secondary method forming machine bead filler thermal-plying locking device to improve, roller 82 side that can be used for transmitting on original triangle glue thermal-adhering device installs triangle rubber prebuckling gripper shoe 41 additional, pressure roller molectron 5 is installed additional at roller opposite side, upright triangle rubber is placed in above roller 82, under prebuckling gripper shoe and pressure roller molectron effect by triangle rubber prebuckling after, then undertaken applying ointment or plaster with the vertical of wire loop by bead filler thermal-plying locking device。

As shown in Figure 4, storing unit after applying ointment or plaster for the triangle rubber of wire loop Yu prebuckling, including bracing frame 11, bracing frame 11 arranges vertical wire loop gripper shoe 92 and triangle rubber gripper shoe 43, triangle rubber gripper shoe 43 is preferably placed at the end of bracing frame 10, wire loop gripper shoe is corresponding with triangle rubber size to triangle rubber prebuckling gripper shoe distance, triangle rubber gripper shoe shape with adapt with triangle rubber Internal periphery, the triangle rubber of the wire loop after applying ointment or plaster with prebuckling is fastened in prebuckling gripper shoe and deposits。Bracing frame arranges multiple wire loop gripper shoe and triangle rubber gripper shoe unit。After being applied ointment or plaster by storing unit, wire loop and prebuckling triangle rubber deposits, it is ensured that deposit the maintenance of tyre bead molectron triangle rubber shape in process, to meet moulding process requirement, it is ensured that the quality stability of product。

First triangle rubber is carried out prebuckling by this utility model, make prebuckling Vee formation glue shape closer to assembly drum drum shoulder size, tyre bead molectron and triangle rubber are easier to realize and meet technological requirement in molding and rolling process, basic solution is choked with resentment and delamination because triangle rubber rolling difficulty causes, reduce the early stage tyre bead bulge phenomenon occurred in tire used process, it is ensured that the quality stability of product。Other technical processs are identical with common all-steel meridian engineered machinery tire, and product cost increases seldom, the change of corresponding tire finished weight is little, one piece tyre structure is substantially free of impact, do not have a negative impact on raising tire technique is by the basis of performance, do not interfere with other serviceabilities of tire。
