Abstract
The utility model discloses a tap water pipe assembly and its press fastening die. The tap water pipe assembly comprises a water pipe and a pipe joint; the water pipe is inserted into the pipe joint and forms a press fastening portion after pressing fastening in a die; the press fastening portion comprises at least six circular arc concave portions distributed on a circumference; each circular arc concave portion is in the central position of a plane; and adjacent planes have an outward convex circular arc surface for transition. The utility model has the advantage that there are six surfaces which are formed through press-fastening of the tap water pipe assembly hexagon; each surface is additionally provided with a concave portion; thereby, greatly enhancing the contact area between the water pipe and the pipe joint, increasing the friction therebetween and improving the drawing resistance therebetween. The press fastening die facilitates the press fastening technique between the water pipe and the pipe joint; and a press fastening chamber structure of the die and the press fastening portion structure of the water pipe assembly are mutually correspondent.
Description
Technical field
The utility model relates to a kind of running water pipe, especially relates to a kind of running water pipe assembly and card pressing mold tool thereof.
Background technique
Present running water pipe all is round basically, installs in the running water pipe process water pipe to be connected in turn usually, at this moment needs to use pipe joint.Water pipe needs specialized mould to block pressure after being inserted into pipe joint, and water pipe is fixed in the pipe joint.Because tap water hydraulic can produce pulling capacity to water pipe and pipe joint, according to present industry standard, water pipe and the pulling capacity between the pipe joint after card is pressed must reach certain value.Must reach 300 kilograms as the tension pull out force between small-bore running water pipe and the pipe joint, adopt common mould to carry out the Hexagon card and press, can't satisfy the requirement of tension pull out force.
Summary of the invention
Technical problem to be solved in the utility model provides higher running water pipe assembly of a kind of tension pull out force and card pressing mold tool thereof.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of running water pipe assembly, comprise water pipe and pipe joint, water pipe is inserted into pipe joint and forms the card splenium after the mould card is pressed, described card splenium comprises at least six arc depression portions that are evenly distributed on the circumference, described each arc depression portion is positioned at the neutral position on a plane, between two adjacent planes outer convex arc surface transition is arranged.
The number of described circular arc concave face is 6.
A kind of card pressing mold tool of running water pipe assembly, its first half module and second half module, described first half module is coupling on second half module, described first half module and described second half module form card and press the chamber, described card is pressed in the chamber and is provided with at least six platforms that are evenly distributed on the circumference, described each platform neutral position is provided with arc-shaped convex portion, between two adjacent platforms interior concaved circular cambered surface is arranged.
Described platform is 6.
Compared with prior art, advantage of the present utility model is that the running water pipe assembly is on six face bases that Hexagon card pressure forms, set up a depressed part on each face again, increased the area of contact between water pipe and the pipe joint widely, increase the frictional force between water pipe and the pipe joint, improved the tension pull out force between water pipe and the pipe joint.
Card pressing mold tool is convenient for the card compression technology between water pipe and the pipe joint.The card of mould presses cavity configuration corresponding mutually with the card splenium structure of conduit assembly.
