Abstract
The utility model discloses the wear-resisting electric power bellows of double-layer coextrusion, the wear-resisting electric power bellows of double-layer coextrusion, comprise body, described body is made up of internal layer and skin, internal layer and skin are ripple tube layer, it is characterized in that: described internal layer and skin are integrated by coextrusion mold, and described internal layer is wearing layer.Bellows is made up of internal layer and skin, and internal layer is antifriction layer, and therefore the inwall of bellows has high-wearing feature, and when installing cables, steel wire rope not easily produces wearing and tearing to bellows inwall, and the wall thickness and the intensity that largely avoid bellows receive impact.
Description
Technical field
The utility model relates to bellows field, particularly relates to the wear-resisting electric power bellows of double-layer coextrusion.
Background technology
Existing bellows is generally single layer structure, because the inwall of bellows wears no resistance, and bellows inner chamber installing cables is pullled by steel wire rope, therefore, the wave trough position wearing and tearing of steel wire rope to bellows inwall are comparatively large, will have influence on wall thickness and the intensity of tubing.Therefore improve Inner tubing layers wearability to seem and be even more important.
Summary of the invention
In order to solve deficiency of the prior art, the purpose of this utility model is to provide the double-layer coextrusion that a kind of pipe material inner wall wearability is high wear-resisting electric power bellows.
For achieving the above object, the utility model is by the following technical solutions:
The wear-resisting electric power bellows of double-layer coextrusion, comprise body, described body is made up of internal layer and skin, and internal layer and skin are ripple tube layer, and described internal layer and skin are integrated by coextrusion mold, and described internal layer is wearing layer.
Described internal layer is by high-antiwear self-lubricating plastic shaping.
Described skin is by PP plastic shaping.
The utility model adopts above technical scheme, has the following advantages:
1, bellows is made up of internal layer and skin, internal layer is by high-antiwear self-lubricating plastic shaping, and therefore the inwall of bellows has high-wearing feature and high-lubricity, when installing cables, steel wire rope not easily produces wearing and tearing to bellows inwall, and the wall thickness and the intensity that largely avoid bellows receive impact.In addition, bellows coefficient of friction is lower, and the speed of application of installing cables strengthens greatly.
2, the internal layer of bellows and skin are integrated by coextrusion mold, and therefore, the good integrity of bellows, internal layer not easily departs from skin, thus can protect bellows better.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details:
Fig. 1 is the structural representation of the wear-resisting electric power bellows of the utility model double-layer coextrusion.
Detailed description of the invention
As shown in Figure 1, the wear-resisting electric power bellows of the utility model double-layer coextrusion, comprises body 1, described body 1 is made up of internal layer 12 and outer 11, internal layer 12 and outer 11 is ripple tube layer, and described internal layer 12 and outer 11 is integrated by coextrusion mold, and described internal layer 12 is wearing layer.
Described internal layer 12 is by high-antiwear self-lubricating plastic shaping.
Described outer 11 by PP plastic shaping.
Bellows is made up of internal layer 12 and outer 11, internal layer 12 is by high-antiwear self-lubricating plastic shaping, therefore the inwall of bellows has high-wearing feature and high-lubricity, when installing cables, steel wire rope not easily produces wearing and tearing to bellows inwall, and the wall thickness and the intensity that largely avoid bellows receive impact.In addition, bellows coefficient of friction is lower, and the speed of application of installing cables strengthens greatly.
The internal layer 12 of bellows and outer 11 is integrated by coextrusion mold, and therefore, the good integrity of bellows, internal layer 12 not easily departs from outer 11, thus can protect bellows better.
