Abstract
The invention relates to an inner liner forming roll for an automobile tire calendaring machine. The inner liner forming roll comprises a roll body; the outer surface of the roll body is provided with a symmetric structure; a first annular face, a second annular face and a third annular face which are different in diameters are sequentially formed from the center to two sides of the symmetric structure along the axis direction; and a circular transition platform is formed between every two adjacent annular faces. The inner liner forming roll is characterized in that transition arcs are formed at a joint part of each annular face and an adjacent circular platform surface. According to the inner liner forming roll for the automobile tire calendaring machine, the transition arcs are formed a joint part of each annular face and an adjacent circular platform surface, so that an inner liner layer can be prevented from being scratched due to a bump between each annular face and the circular transition platform surface during calendaring and forming, and the quality of a product can be ensured.
Description
Technical field
The present invention relates to a kind of automobile tire calender, particularly a kind of steamer tire calender inner liner forming roll of avoiding the unnecessary waste of rubber.
Background technology
Tire calender inner liner forming roll is for the moulding of tyre element, and traditional middle part, forming roll surface is provided with flat isosceles trapezoid groove, for realizing the reasonable Arrangement of tyre stock.Its shortcoming is: the profile inaccuracy of forming roll, the effective rate of utilization of sizing material is low, causes raw-material waste.There is at present a kind of calender inner liner forming roll, comprise roll body, roll body outer surface is symmetrical structure, it is therefrom disposed with the first different ring surface of diameter, the second ring surface, the 3rd ring surface, the 4th ring surface in mind-set both sides along axis direction, between each adjacent annular face, be provided with transition circle table top, profile is accurate, is applicable to the tire of 12 R22.5 series, rubber effective rate of utilization maximizes, and has reduced raw-material waste.But still there is certain shortcoming in it: the joining place of transition circle table top and ring surface easily causes scratching, scratching of inner liner, affects product quality.
Summary of the invention
The technical problem to be solved in the present invention is to provide the steamer tire calender inner liner forming roll that a kind of chamberlain's of avoiding layer scratches.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of steamer tire calender inner liner forming roll, comprise roll body, described roll body outer surface is symmetrical structure, it is therefrom disposed with the first different ring surface of diameter, the second ring surface, the 3rd ring surface in mind-set both sides along axis direction, between each adjacent annular face, is provided with transition circle table top; Its innovative point is: the junction of described each ring surface and adjacent transition circle table top is provided with transition arc.
Further, the radius R of described transition arc is 520-530mm.
The invention has the advantages that: the junction of each ring surface and adjacent transition circle table top is provided with transition arc, when it can avoid calendering formation, change escape by luck and transition circle table top between projection cause scratching of inner liner, guarantee product quality.
Accompanying drawing explanation
Fig. 1 is steamer tire inner liner layer forming roller structure for calendar adopting schematic diagram of the present invention.
The specific embodiment
As shown in Figure 1, comprise roll body 1, roll body 1 outer surface is symmetrical structure, it is therefrom disposed with diameter different the first ring surface 2, the second ring surface 3, the 3rd ring surface 4 in mind-set both sides along axis direction, between the first ring surface 2, the second ring surface 3, transition circle table top 5 is set, between the second ring surface 3, the 3rd ring surface 4, transition circle table top 6 is set, and the junction of each ring surface and adjacent transition circle table top is provided with transition arc, the radius R of this transition arc is 520-530mm.
Claims (2)
1. a steamer tire calender inner liner forming roll, comprise roll body, described roll body outer surface is symmetrical structure, and it is therefrom disposed with the first different ring surface of diameter, the second ring surface, the 3rd ring surface in mind-set both sides along axis direction, between each adjacent annular face, is provided with transition circle table top; It is characterized in that: the junction of described each ring surface and adjacent transition circle table top is provided with transition arc.
2. steamer tire calender inner liner forming roll according to claim 1, is characterized in that: the radius R of described transition arc is 520-530mm.
