Abstract
The invention relates to an inner liner layer forming roller structure for a calender adopting an extrusion method, which comprises a roller body and has the innovation point that the outer surface of the roller body is in a symmetrical structure, a first annular surface, a second annular surface, a third annular surface and a fourth annular surface with different diameters are sequentially arranged in the axial line direction of the roller body from the center to both sides, and a transition round table top is arranged between every two adjacent annular surfaces. The outer surface of the roller body is in the symmetrical structure, the first annular surface, the second annular surface, the third annular surface and the fourth annular surface which have different diameters are sequentially arranged in the axial line direction of the roller body from the center to both sides, the transition round table top is arranged between every two adjacent annular surfaces, the sectional surfaces are precise, the structure is applicable to 12R22.5 series tires, the effective utilization rate of rubber is maximum, and the raw material waste is reduced.
Description
Technical field
The present invention relates to a kind of extrusion molding calender, particularly a kind of extrusion molding calender inner liner forming roll structure of avoiding the unnecessary waste of rubber.
Background technology
Extrusion molding calender inner liner forming roll is used for the moulding of tyre element, and traditional middle part, forming roll surface is provided with flat isosceles trapezoid groove, is used to realize 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.
Summary of the invention
The technical problem that the present invention will solve provides a kind of extrusion molding calender inner liner forming roll structure of avoiding the unnecessary waste of rubber.
For solving the problems of the technologies described above; Technical scheme of the present invention is: a kind of extrusion molding calender inner liner forming roll structure; Comprise roll body; Its innovative point is: said roll body outer surface is a symmetrical structure, and it therefrom is disposed with the first different ring surface of diameter, second ring surface, the 3rd ring surface, the 4th ring surface in the mind-set both sides along axis direction, is provided with the transition circle table top between each adjacent annular face.
Further, the diameter of said first ring surface is that the diameter of Φ 395.30, the second ring surfaces is that the diameter of Φ 393.42, the three ring surfaces is that the diameter of Φ 397.18, the four ring surfaces is Φ 400.
The invention has the advantages that: the roll body outer surface is a symmetrical structure; It therefrom is disposed with the first different ring surface of diameter, second ring surface, the 3rd ring surface, the 4th ring surface in the mind-set both sides along axis direction; Be provided with the transition circle table top between each adjacent annular face, profile is accurate, is applicable to the tire of 12 R22.5 series; The maximization of rubber effective rate of utilization has reduced raw-material waste.
Description of drawings
Accompanying drawing is extrusion molding calender inner liner forming roll structural representation among the present invention.
The specific embodiment
Shown in accompanying drawing; The present invention relates to a kind of extrusion molding calender inner liner forming roll structure of avoiding the unnecessary waste of rubber; Comprise roll body 1; The outer surface of roll body 1 is a symmetrical structure, and it therefrom is disposed with the first different ring surface 2 of diameter, second ring surface 3, the 3rd ring surface 4, the 4th ring surface 5 in the mind-set both sides along axis direction, is provided with the transition circle table top between each adjacent annular face: establish transition circle table top 6 between first ring surface 2 and second ring surface 3; Establish between second ring surface 3 and the 3rd ring surface 4 between transition circle table top 7, the three ring surfaces 4 and the 4th ring surface 5 and establish transition circle table top 8.
Concrete, the diameter of first ring surface 2 is Φ 395.30, axial distance is 100mm; The diameter of second ring surface 3 is Φ 393.42; Axial distance is 65mm, and the diameter of the 3rd ring surface 4 is Φ 397.18, and axial distance is 120mm; The diameter of the 4th ring surface 5 is Φ 400, and it axially extends to roll body 1 end face always.The axial distance of transition circle table top 6 is 25mm, and the axial distance of transition circle table top 7 is 50mm, and the axial distance of transition circle table top 8 is 20mm.
