Abstract
The invention relates to a structure of tyre-claw roller molding machine capable of making the stress on tyre equal, a molding machine orderly attaches to the half-finished tyre (3) of a jig (2) set on a molding cylinder (1) utilizing a claw roller (5) set on a claw arm (4), a tube (6) comprising a flexible layer (8) and a reinforcing layer (9) is set between an attached tyre (3) and the claw roller. In the molding process of manufacturing the belt tyre, the molding machine makes the stress equally between the claw roller orderly attaching the tyre and the tyre with the structure of the tube (6) so as to reduce the defective products in the process.
Description
Technical field
The present invention relates in the make-up machine in molding procedure stage of radial manufacturing process, make the uniform structure of tyre element pressure, so that between the handgrip roller that tyre element is attached successively and this tyre element, apply uniform pressure, thereby in the tire building process, reduce substandard products.
Background technology
As everyone knows, in the molding procedure that tire is made, carry out following operation: all component parts that will be used in tire attach successively in make-up machine and make cylindric green tire, and molding procedure is the tire quality almost to be played the important operation of decisive role.According to the difference of tyre kind, make-up machine is also different.Shape according to the specification forming tube of tire is variant, determines the shape and the size of green tire thus.
In such tire building operation, the existing handgrip roller molding machine that radial is carried out to type adopts a plurality of handgrip rollers that distribute along circumferencial direction in forming tube, surface to tyre element is directly pushed, thereby makes tyre element roll (Turn up) and moulding when moulding.
In this case, the part and the discontiguous part that can exist the handgrip roller directly to contact with tyre element.Thus, in forming process, there is uneven pressure distribution on the tyre element surface.Uneven pressure distribution like this will become makes the underproof major reason of final tire product.
On the other hand, in the prior art,, also adopt the method that the pressure of the handgrip that tyre element pushed when the moulding is controlled in order to reduce this problem.In addition, the structure change that also discloses shape by pair roller and handgrip reduces the uneven technology of pressure that the boundary member at the roller contact site produces.
But although make great efforts to overcome this problem in the prior art, the pressure non-uniform phenomenon between the roller still exists, so in the prior art still can be in inside tires generation carcass, steel wire density uneven phenomenons such as (EPI).
Summary of the invention
The present invention proposes in order to solve above-mentioned existing issue, its purpose is, what a kind of tire handgrip roller molding machine was provided makes the uniform structure of tyre element pressure, this structure is in the tire building operation, can be between handgrip roller and semifinished part equably dispersive pressure distribute, reduce the defect rate of product.
In order to achieve the above object, what the present invention relates to a kind of tire handgrip roller molding machine makes the uniform structure of tyre element pressure, described make-up machine utilizes double finished tire parts of handgrip roller to attach successively, wherein, is provided with flexible pipe between the tyre element of described attaching and handgrip roller.Preferably, described flexible pipe comprises flexible layer and enhancement Layer, and described enhancement Layer is positioned at the inboard of described flexible layer.The thickness of described flexible layer is preferably 1mm～10mm, and the thickness of described enhancement Layer is preferably less than 2mm.Described flexible layer can be made of elastomeric material, and described enhancement Layer can be made of the carcass material.
Description of drawings
Fig. 1 is for adopting the partial section of radial tire forming machine of the present invention;
Fig. 2 is the partial cross section's enlarged drawing as the flexible pipe of major part of the present invention.
The specific embodiment
Below, describe the present invention with reference to the accompanying drawings in detail.
Fig. 1 is for adopting the partial section of radial tire forming machine of the present invention, and Fig. 2 is for adopting the partial cross section's enlarged drawing at the flexible pipe of Fig. 1.
The present invention relates to utilize 5 pairs on the handgrip roller that is installed on handgrip arm 4 ends to be placed on the make-up machine that the semi-finished product tyre element 3 on the anchor clamps 2 of forming tube 1 attaches successively, wherein, between the tyre element 3 of described attaching and handgrip roller 5, flexible pipe 6 is set.In the cross section of this flexible pipe 6, heart place has air layer 7 therein, has flexible layer 8 and enhancement Layer 9 around it.Enhancement Layer 9 is positioned at the inboard of flexible layer 8.
Wherein, the flexible layer 8 of described flexible pipe 6 is soft, and by constituting as pliable and tough materials such as rubber, its thickness is at 1mm～10mm.In addition, enhancement Layer 9 materials of described flexible pipe 6 are different with the material of flexible layer 8, can be made of any material that can prevent to be out of shape such as the material of carcass, and its thickness is preferably less than 2mm.
That is to say that described flexible pipe 6 has basic pipe cross-section, can have big expansion and contraction, soft, flexible on the whole.Therefore, in the longitudinal direction,, when being stressed, can stretch changeably, though diameter in a circumferential direction keeps necessarily when being stressed, also can stretching changeably at ordinary times though keep certain length at ordinary times.
Therefore, when tyre element 3 is rolled, this flexible pipe 6 can lead according to the pressure that makes handgrip roller 5 equally distributed mode on the whole surface of tyre element 3, can improve thus the inhomogeneous moulding unfavorable condition that causes of pressure takes place when carrying out tire building.
The uniform structure of parts pressure that makes of aforesaid tire handgrip roller molding machine of the present invention has following advantage:
(1) when tire building, between handgrip roller and semi-finished product tyre element, plays this handgrip roller pressure homodisperse effect on parts surface.
(2) when tire building, can reduce the defect rate of the product that causes because of pressure is inhomogeneous.
Claims (5)
