Abstract
The utility model relates to a metal winding pad. The pad is provided with a groove on the circumference of the inner round and is provided with a convex part on the circumference of the outer round. A thin metal sheet is tightly wound to form the pad, and namely, the pas is formed from a sheet in a winding mode, wherein, the shapes of the groove and the convex part are consistent basically. With easy manufacture and low cost, the pad of the utility model especially brings a favorable effect on the shaping of the groove or the convex part.
Description
The utility model relates to a kind of pad, particularly relates to a kind of spiral wound gaskets.
Present metallic shim, generally be to adopt sheet metal turning to be processed into, when needing groove or protuberance on the circumference of the interior circle of pad and cylindrical, this just brings a lot of difficulties to manufacturing, improved processing cost simultaneously, the protuberance on the excircle of pad easily comes off in addition.
The purpose of this utility model overcomes the deficiencies in the prior art exactly, and a kind of spiral wound gaskets is provided, thereby has reduced processing cost, and is easy to manufacture, and the protuberance on the excircle of pad is comparatively firm, difficult drop-off.
The purpose of this utility model realizes by following manner, the utility model spiral wound gaskets, fluted on its interior round week, on its cylindrical circumference, protuberance is arranged, this pad is to be made of the thin tight coiling of metal sheet, promptly constitute wherein said groove shapes and described protuberance shape basically identical with canoe by sheet material.
Pad of the present utility model is processed into like this, thin metal sheet closely twines on model, required construction profile is arranged on model, if any flange, on the pad inner circumference of moulding, can form corresponding grooves like this, after winding reaches given size, fix the sheet material end, it should be clearly know that, at this moment on pad cylindrical circumference, be formed with corresponding protuberance.
The utility model pad easy processing, cost is low, is shaped especially for described groove or protuberance and brings favourable effect.
Below in conjunction with accompanying drawing pad of the present utility model is described.
Fig. 1 is the front view of pad of the present utility model;
Fig. 2 is the generalized section of Fig. 1.
Referring to Fig. 1 and 2, go up in the interior round week of pad of the present utility model flutedly 1, and protuberance 2 was arranged on round week outside, this pad is to be made of thin metal sheet 3 tight coilings.
Claims (1)
1, a kind of spiral wound gaskets, it is characterized in that round week of this pad going up fluted within it, and protuberance is arranged on its cylindrical circumference, this pad is to be made of the thin tight coiling of metal sheet, promptly constitute wherein said groove shapes and described protuberance shape basically identical with the form of twining by a sheet material.
