Abstract
The utility model discloses a sector block for a radial tyre building drum. The sector block comprises a drum surface part, an intermediate part, a reversely-coated end part and a bottom which are integrally formed, wherein the drum surface part is positioned at the top end of the sector block; the top end of the intermediate part is connected with the drum surface part; the bottom end of the intermediate part is connected with the top end of the bottom; the bottom end of the reversely-coated end part is connected with the bottom end of the bottom; and the top end of the intermediate part is in smooth transition with the connecting part of the drum surface part. The sector block disclosed by the utility model is used for carrying out reinforcing treatment on a stress-concentrated area, so that the breaking phenomenon of the sector block is thoroughly avoided; and the appearance and the reject ratio of the tyre bead part are remarkably improved. The sector block has the advantages of simple structure and convenience in use.
Description
Technical field
The utility model relates to a kind of shaped device of tire, in particular a meridian line tyre assembly drum is used secter pat.
Background technology
The assembly room is the composing room of tire, the quality (as: uniformity and dynamic balancing etc.) and the outward appearance (delamination, breach, bubble etc.) that assemble and badly directly influence finished tire of component materials.At present, fracture of radial (TBR) capsule drum secter pat and welding rear curved phenomenon are serious.The severe patient single-drum has the fracture of nearly 1/2 secter pat, can only carry out soldering to it after the fracture, because the crack can't complete matching, therefore causes welding back secter pat to have phenomenon crooked, dislocation.In addition, it is unreal to cause the position, rim of the mouth to suppress owing to anti-package point position is on the low side.
The reason that this phenomenon produces mainly contains:
1, in the secter pat structure, the top of pars intermedia is a step transition with the facial junction of drum, has stress raiser, and comparatively weak here, how from here secter pat fracture, bending.
2, forming operation is improper.When tire is unloaded in moulding, do not unload tire (secter pat falls behind the capsule venting down) on request automatically, be prone to get into the bottom of secter pat when causing reverse-wrapped capsule to fall after rise, secter pat is blocked be difficult for falling.Field operation person is not in time expanded secter pat when secter pat blocks, and directly reverse-wrapped capsule inflation just causes secter pat fracture, bending easily.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, provides a meridian line tyre assembly drum to use secter pat, through fan-shaped block structured being changed the fault rate that reduces secter pat.
The utility model realizes that through following technical scheme the said secter pat of the utility model comprises drum face, pars intermedia, anti-package end and bottom; Drum face, pars intermedia, anti-package end and bottom are one-body molded, and the drum face is positioned at the top, and the top of pars intermedia is connected with drum is facial, and the bottom of pars intermedia is connected with the top of bottom, and the bottom of anti-package end is connected with the bottom of bottom; The top of said pars intermedia and the facial junction smooth transition of drum.
The junction arc-shaped transition of the top of said pars intermedia and the inboard of drum face, the top of pars intermedia and facial junction, the outside straight transitions of drum, this regional intensity is strengthened in the concentrated area that eliminates stress.
Said drum is facial to coincide at the intersection point of anti-package end and the summit of anti-package end, increases the height of anti-package end, makes the anti-package in rim of the mouth suppress more even.
Facial width and the height ratio scope of said drum is 0.5～1.The facial width of minimizing drum, thus the gap that increases secter pat and capsule preparations avoids secter pat to be blocked by capsule and difficult whereabouts.
The utility model is compared prior art and had the following advantages: consolidation process is carried out in the utility model counter stress concentrated area, and the secter pat phenomenon of rupture is thoroughly effected a radical cure; The profile at tyre rim position and fraction defective have also obtained significant change; Simple in structure, easy to use.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Embodiment in the face of the utility model elaborates down; Present embodiment is being to implement under the prerequisite with the utility model technical scheme; Provided detailed embodiment and concrete operating process, but the protection domain of the utility model is not limited to following embodiment.
As shown in Figure 1, the secter pat of present embodiment comprises drum face 1, pars intermedia 2, anti-package end 3 and bottom 4; Drum face 1, pars intermedia 2, anti-package end 3 and bottom 4 are one-body molded, and drum facial 1 is positioned at the top, and the top of pars intermedia 2 is connected with drum facial 1, and the bottom of pars intermedia 2 is connected with the top of bottom 4, and the bottom of anti-package end 3 is connected with the bottom of bottom 4; The junction smooth transition of the top of said pars intermedia 2 and drum facial 1.
The junction arc-shaped transition of the top of pars intermedia 2 and the inboard of drum facial 1, junction, the outside straight transitions of the top of pars intermedia 2 and drum facial 1, this regional intensity is strengthened in the concentrated area that eliminates stress.
Drum facial 1 coincides at the intersection point of anti-package end 3 and the summit of anti-package end 3, has in fact increased the about 8mm of height h1 of anti-package end 3, makes the anti-package in rim of the mouth suppress more even.
The width of drum facial 1 is 0.7 with height h2 ratio.The width of drum facial 1 is the direction of vertical paper among Fig. 1, the about 12mm of width of reality minimizing drum facial 1, thus the gap that increases secter pat and capsule preparations avoids secter pat to be blocked by capsule and difficult whereabouts.
