Problems solved by technology

[0005] In the prior art, in order to achieve a more ideal shock absorption effect for metal hoses, two corrugated pipes nested in each other are generally used, and shock-absorbing materials are arranged in the two corrugated pipes, or multiple wires are installed in the net sleeve. The small bellows are arranged side by side to achieve further shock absorption effect. The two bellows in the first scheme will cause incongruity during the bending process, and will also have a certain impact on the bending angle range. The second scheme not only It only has a large impact on the bending angle range, and at the same time, because the inner diameter of the bellows becomes smaller and the number of bellows increases, it brings inconvenience to subsequent installation and use

Embodiment 1

[0027] Such as figure 1 and figure 2 As shown, a corrugated metal hose with a shock absorbing function is shown, which includes an annular metal bellows 1 and joints 2 welded at both ends thereof. Metal jacket 3, said metal jacket 3 is welded by two semicircular snap rings 10, the two ends of the snap rings shown are respectively provided with a flat lug plate 11, said metal jacket 3 and annular metal bellows 1 A glass fiber cloth layer 4 is filled in between, and a metal mesh sleeve 8 is arranged outside the annular metal bellows 1, and the metal mesh sleeve 8 is welded and fixed to the joints 2 at both ends.

Embodiment 2

[0029] Such as image 3 and Figure 4 As shown, there is a rubber layer 5 on the outside of the peak position of the annular metal bellows 1, and the glass fiber cloth layer 4 is bonded to the outside of the rubber layer 5 by resin. The annular metal bellows 1 and the metal jacket 3 The gaps in between are filled by the rubber layer 5 . The crest of the annular metal bellows 1 is provided with a plurality of notches 6, the inner side of the rubber layer 5 is provided with a groove 9 wrapping the crest, and the groove 9 is provided with a plurality of notches to cooperate with the notches. The raised 7.

[0030] A method for producing a corrugated metal hose with a shock-absorbing function, the specific steps are as follows:

[0031] 1) A plurality of notch groups are pressed along a straight line on multiple crests of the annular metal bellows 1, so that the notches 6 between each row of crests are aligned in a straight line, and the number of notch groups is not less than ...

Abstract

The invention provides a production method for a corrugated metal flexible pipe with a damping function. The production method comprises the main production steps that (1) a plurality of notch groupsare pressed along a straight line in a plurality of wave peaks of an annular metal corrugated pipe; (2) the pressed annular metal corrugated pipe is placed in a groove corresponding to the annular metal corrugated pipe in structure, liquid rubber is poured into the groove, and a rubber layer is formed after solidifying; (3) a glass fiber cloth layer is adhered to the rubber layer; (4) two semicircular clamping rings are clamped into a wave peak position located on each annular metal corrugated pipe, and spot welding is conducted on lug plates located at the two ends of each clamping ring; (5)the glass fiber cloth layers and the rubber layers located at the wave trough positions of the annular metal corrugated pipe are cut off; and (6) upper connectors are mounted at the two ends of the annular metal corrugated pipe, and outer-layer metal sleeves are welded. According to the production method for the corrugated metal flexible pipe with the damping function, the wave peak positions of the annular metal corrugated pipe are sleeved with the annular metal sleeves so that the better damping effect can be achieved, and meanwhile, bending of the corrugated pipe cannot be hindered.

Description

technical field [0001] The invention relates to a method for manufacturing a corrugated metal hose with shock-absorbing function, belonging to the field of metal hoses. Background technique [0002] Metal hose is an important connecting component in engineering technology, which is composed of corrugated flexible pipe, net sleeve and joint. Used as compensating elements, sealing elements, connecting elements and shock absorbing elements in various gas transmission, infusion pipeline systems and length, temperature, position and angle compensation systems, used in aerospace, petrochemical, mining electronics, machinery shipbuilding, medical treatment Health, textile electronics, energy construction and other fields. The latest national specification for metal hoses is "General Technical Conditions for Corrugated Metal Hose" (GB / T14525-2010), which came into effect on October 1, 2011. [0003] Corrugated metal hose (referred to as bellows) is a high-quality flexible pipe in ...
