Description

一种蒸汽输送软管及其专用成形工装 A steam delivery hose and special shaped tooling

技术领域 FIELD

[0001]本发明涉及一种气体输送软管,尤其是一种带导线的蒸汽输送软管,同时还涉及其专用成形工装,属于软管技术领域。 [0001] The present invention relates to a gas delivery hose, in particular a steam delivery hose with wires, and also relates to its special shaped tooling, belonging to the technical field hose.

背景技术 Background technique

[0002] 据申请人了解,用于蒸汽熨斗等处的现有蒸汽输送软管常需要同时传递电流或电信号,因此其典型结构如图1和图2所示,主要含有截面为圆缺形的软管主体1以及附着于软管主体外的导线2。 [0002] It is understood applicant, for conventional steam iron steam delivery hose, etc. often need to transfer electrical current or signal, so the typical structure as shown in FIG 1 and FIG 2 comprising mainly a circular segment-shaped cross-section the hose body 1 and a wire attached to the outer hose body 2. 导线2通常由至少一根导体芯2-1、包覆导体芯的至少一层绝缘层2-2,以及套在绝缘层之外的绝缘保护套管2-3构成。 Conductor 2 generally consists of at least one conductor core 2-1, at least one conductor wire coated with the insulating layer 2-2, and a jacket outside the insulating layer constituting the insulating protective tube 2-3. 为了使软管主体1和导线2形成一个整体,蒸汽输送软管最外层包裹编织层(图中未示)。 In order to make the hose main body 1 and the wire 2 is formed integrally, outermost wrap steam delivery hose woven layer (not shown).

[0003] 实践表明,使用过程中,上述现有技术存在以下问题:1)由于导线不具有可拉伸性,因此软管弯曲时的柔韧性差,导线在反复弯曲后容易拉断;2)弯曲时软管主体容易折瘪,导致气流输送不畅,3)编织层包裹后的软管截面在导线附着部位无法形成与软管主体圆缺相配的完整圆弧,因此外形不圆滑,握持时手感差。 [0003] Practice shows that, during use, the above-described prior art has the following problems: 1) Since the wires having no stretchability, and thus when the flexible hose is bent difference, easy to pull off the wire after repeated bending; 2) Flexural when deflated the hose body off easily, leading to poor air transportation, 3) cross section of the hose after wrapping the wire braid in the attachment portion can not form a complete lack of matching with the circular arc round the hose body, and therefore is not smooth shape, when the grip feel bad.
