Abstract
The present invention relates to connect the manufacture method of the jam-on stainless steel pipe fitting of aluminium-plastic composite pipe, be characterized in: this pipe fitting is welded by pipe fitting and the internal lining pipe made respectively.Its useful effect is: because pipe fitting and internal lining pipe are made respectively, the geometric shape of each part is simple, thereby is convenient to processing; And the thickness of pipe fitting and internal lining pipe be owing to can select different thickness by its function of use respectively, thereby few with material.Low with the method pipe fitting processed cost, performance is good.
Description
Affiliated technical field
The present invention relates to be used for Lian Jie Aluminum and mould the production method that Complex closes the jam-on stainless steel pipe fitting of pipe.
Technical background
Be used to connect the clamp-press type pipe of aluminium-plastic composite pipe at present, the internal lining pipe of pipe fitting port and pipe fitting are an integral body, and the characteristics of its production are: be to make by turning, boring after material is forged into the profile of pipe fitting.Fluted on the internal lining pipe of pipe fitting, cushion rubber is arranged in the groove.When aluminium-plastic composite pipe was connected with pipe fitting, the plastic-aluminum pipe box was in internal lining pipe outside, by the outer sleeve of card gland aluminium-plastic composite pipe outside, with the crowded modification of aluminium-plastic composite pipe and be connected with pipe fitting.The general copper alloy made that is easy to process that adopts of this pipe fitting, because the intensity of Cuprum alloy is lower, pipe fitting has to keep certain wall thickness, thereby the Cuprum alloy large usage quantity of pipe fitting, the pipe fitting cost height of making, its internal lining pipe particularly: internal lining pipe has not only required certain intensity, could guarantee when card is pressed, not break, to process the groove of putting cushion rubber on the tube wall of internal lining pipe in addition, more need to increase the wall thickness of internal lining pipe, the internal lining pipe of heavy wall not only material consumption is big, also makes the pipe fitting latus rectum diminish.
Summary of the invention
The manufacture method of the jam-on stainless steel pipe fitting of the connection aluminium-plastic composite pipe that the present invention relates to is characterized in: this pipe fitting is welded by pipe fitting and the internal lining pipe made respectively.
Its useful effect is: because pipe fitting and internal lining pipe are made respectively, the geometric shape of each part is simple, thereby is convenient to processing; And the thickness of pipe fitting and internal lining pipe be owing to can select different thickness by its function of use respectively, thereby few with material.Low with the method pipe fitting processed cost, performance is good.

Embodiment
Below, with embodiment the present invention is described in further detail in conjunction with the accompanying drawings:
Fig. 1 represent the pipe fitting mouth structure figure of traditional copper pipe fitting in can see: have on the internal lining pipe that connects as one with pipe fitting in tooth and groove, the groove cushion rubber arranged.When aluminium-plastic composite pipe was connected with pipe fitting, the plastic-aluminum pipe box was in the internal lining pipe outside, and cutting ferrule is enclosed within outside the plastic-aluminum pipe.Available dedicated mould extruding cutting ferrule squeezes modification with aluminium-plastic composite pipe and is connected with pipe fitting.Can see among the figure, because the thickness of internal lining pipe is bigger, so stimulating the menstrual flow of pipe fitting is little.
Can see in the pipe fitting mouth sectional drawing of the jam-on stainless steel pipe fitting of the present invention that Fig. 2 represents: the internal lining pipe of pipe fitting is the port (use argon arc welding, or the mode of soldering can be welded on internal lining pipe the port of pipe fitting easily) that is connected pipe fitting by welding.Because stainless strength ratio Cuprum alloy is much bigger, and toughness height, so the wall thickness of internal lining pipe can be done thinlyyer (to lay the groove of cushion rubber, available spinning or other mode extrude on the internal lining pipe of thin-walled, and do not need to come the darker groove of turning with thick walled tube, thin internal lining pipe can not influence the shorter tooth of processing tooth depth on the liner tube wall yet).The clamp-press type pipe of Zhi Zuoing is processed simply in this way, and material consumption is few, and the fabricating cost of pipe fitting is low.Simultaneously, the latus rectum of this pipe fitting is bigger than the latus rectum of the internal lining pipe that comes the turning groove with thick walled tube.
Can see in the sectional drawing of the outer stainless steel clamp-press type pipe mouth that is covered with enlarging that Fig. 3 represents: the structure of pipe fitting mouth is identical with Fig. 2.The enlarging that wild card puts be for pipe fitting with outer cutting ferrule and pipe fitting can be connected in one easily after aluminium-plastic composite pipe is connected.(see figure 5)
In the jam-on stainless steel pipe fitting of Fig. 4 and sectional drawing after aluminium-plastic composite pipe is connected, can see: radially block the outer cutting ferrule of gland outside aluminium-plastic composite pipe with special tool, make outer cutting ferrule, aluminium-plastic composite pipe, simultaneously radial deformation take place, make on the one hand cushion rubber in the internal lining pipe groove fill up space between groove and plastic-aluminum combined inner tube wall, guaranteed the sealing function of pipe fitting, on the other hand, also make the tooth on the liner tube wall embed the internal face of aluminium-plastic composite pipe, make that aluminium-plastic composite pipe is difficult for coming off from internal lining pipe, guaranteed that the resistance to plucking of pipe fitting takes off function.
Can see in jam-on stainless steel pipe fitting pipe fitting that Fig. 5 outer is with enlarging and sectional drawing after aluminium-plastic composite pipe is connected: catenation principle and Fig. 4 of aluminium-plastic composite pipe and pipe fitting are identical, so do not giving unnecessary details, different is: when radially blocking the outer cutting ferrule of gland outside aluminium-plastic composite pipe, the flared end of outer cutting ferrule is buckled on the pipe fitting, is connected to become integral body with pipe fitting.
Claims (2)
1, connect the making method of the clamp-press type pipe of aluminium-plastic composite pipe, be characterized in: pipe fitting and neck bush are made respectively, and the internal lining pipe of pipe fitting port is the mode with welding, are connected the mouth end of pipe fitting.
2, as the outer cutting ferrule of pipe fitting as described in the claim one, be characterized in: an end of outer cutting ferrule has enlarging.
