Abstract
The present invention relates to a Tyre blank shape holding device, specifically speaking, relates to a device which modifies the position of the raw tyre with certain time interval to improve the uniformity and reduce the substandard product rate of the tyre during the keeping process freely. In the supporting device which holds the raw tyre (2) shape through the cloth (3) using the loading stand (1) between two layers, the cloth (3) to hold the raw tyre (2) through the supporting tables (1a) of the above mentioned loading stand (1) can rotate through the rotating roller (4a,4b) in two sides which is drove by driving roller (6) inner certain distance, which hold the raw tyre (2) shape.
Description
Technical field
The present invention relates to a kind of green tire that moulding has finished in the manufacturing process of tire and drop into before the vulcanization process device that the shape to this green tire keeps, in more detail, the present invention relates to a kind ofly in the keeping of green tire, the storage position of this green tire is revised freely and be improved the uniformity (uniformity) of tire and reduce the tyre blank shape holding device of defect rate every opening certain hour.
Background technology
Usually, tire is produced in the following manner: add and mix various rubber and chemical reagent obtaining compounded rubber, and this compounded rubber rolled or extrude form semi-finished product, these semi-finished product are carried out moulding after through combination again, make green tire thus.This green tire passes through vulcanization process again, promptly drops in the vulcanization plant and also exerts pressure under the temperature of regulation within a certain period of time, makes compounded rubber carry out chemical bond, thereby becomes finished tire.
Usually, in vulcanization process, as shown in Figures 2 and 3, through before the green tire 2 made of molding procedure according to different size pending sulfuration such as before vulcanization plant.At this moment, in order to load more green tire, use green tire loading frame (Green tire rack) 1.
Can green tire drop in the sulfurizing mould with the state of maintenance with the essentially identical circle of finished tire, with improve the quality, especially improve uniformity direct relation is arranged, the shape of green tire bead part is when dropping into sulfurizing mould, and approaching more ellipse increases the incidence of substandard products more.
What Fig. 2 represented is that green tire 2 places the situation on the green tire loading frame 1, and Fig. 3 observes the figure that Fig. 2 obtains from the side.
Existing green tire loading frame 1 constitutes in the mode that can take care of a plurality of green tires according to the size of tire, and green tire places on the cloth 3.At this moment, cloth is fixed on the loading attachment.Along with green tire is waited on loading attachment for a long time, as shown in Figure 3, because of its shape of deadweight of green tire becomes ellipse.
Usually, in order to prevent the distortion of green tire, the operator is spending through by manual mode green tire being rotated about 90 after the regular hour.
Yet, after the process regular hour, it is to need a lot of labours that the operator is rotated the green tire of One's name is legion in manual mode, and the situation that the operator misses a part of green tire may take place, thereby has uniformity that reduces tire and the problem that produces substandard products.
Summary of the invention
Therefore, in order to solve above-mentioned the problems of the prior art, the purpose of this invention is to provide a kind of tyre blank shape holding device, separating the regular hour in the green tire keeping of this device after molding procedure finishes revises freely to the storage position of this green tire, thereby can improve the uniformity of tire and reduce defect rate.
Constituted mode of the present invention for achieving the above object is, in the tyre blank shape holding device that by cloth green tire is kept on two-layer loading frame, above-mentioned cloth can rotate certain distance by the two sideway swivel rollers that driven by drive division.
Description of drawings
Fig. 1 is the structure chart that the present invention is used for green tire;
Fig. 2 is the front view of existing green tire supporting arrangement;
Fig. 3 is the side view of Fig. 2.
The specific embodiment
Hereinafter with reference to accompanying drawing the preferred embodiments of the present invention are described.
Shown in Figure 1 is the green tire 2 that keeps on two-layer loading frame 1 according to the present invention, for using identical Reference numeral with existing structure same section.
As shown in the figure, constituted mode of the present invention is, in the tyre blank shape holding device that on two-layer loading frame 1, keeps by 3 pairs of green tires 2 of cloth, the cloth 3 that on each supporting station 1a of above-mentioned loading frame 1 green tire 2 is kept can rotate certain distance by two sideway swivel roller 4a, the 4b that is driven by drive division 6, in this way this green tire 2 is kept.
That is to say that the supporting station 1a of above-mentioned loading frame 1 is made of the two-layer of lower layer part and upper layer part, and have roller 4a, the 4b that cloth 3 can be wrapped on each supporting station 1a, this roller can be rotated by the power of drive division 6.
Above-mentioned drive division 6 is because be formed on both sides roller 4a, 4b side, so behind cloth 3 rotation certain distances, can opposite spin.
In addition, the power of drive division 6 that is used to make rotation roller 4a, 4b rotation is by can moving to the timer (not shown) that the regular hour is adjusted, and rotary distance can also be regulated according to the size of green tire 2.
By constituting green tire loading frame 1 in the above described manner, just can prevent owing to the outward appearance distortion of waiting for the green tire that produces for a long time.
On the other hand, following table 1 is that the use supporting arrangement of the present invention that expression obtains by test loads before the green tire and the tables of data that concerns afterwards.Hence one can see that, better according to the effect of tyre blank shape holding device of the present invention, good more in the low more expression effect of table 1 intermediate value.
Table 1
To model is the front/rear inhomogeneity data comparison sheet of the green tire of 225/60R16V
*RFV.:Radial Force Variation (variation of radial load) is applying in the middle of the rotating a circle under the load situation about being rotated, in the change of the opposite force that vertically produces.
LFV.:Lateral Force Variation (variation of cross force) is applying in the middle of the rotating a circle under the load situation about being rotated, the deviation of the opposite force that produces at left and right directions.
CON.:Conicity (tapering), the power to certain transverse direction inclination of tire when rotation and irrelevant to rotation direction.
As mentioned above, tyre blank shape holding device of the present invention can prevent to finish in molding procedure the outward appearance distortion of back issuable this green tire because green tire waits as long for, thereby has uniformity that improves tire and the effect that reduces defect rate.
Claims (2)
1. a tyre blank shape holding device upward keeps green tire (2) by cloth (3) at two-layer loading frame (1), it is characterized in that,
