Abstract
A technology for making the connecting spiral thread of the water tube made of plastic stainless steel features use of rolling method or die pressing method, which including inserting core die in the water tube, fixing rolling dies to machine-tool fixing the core die and water tube between rolling dies, and rolling while gradually increasing pressure.
Description
Technical field
The invention belongs to the machining scope, particularly a kind of preparation method of plastic stainless steel water pipe joint thread.
Background technology
At present the most of usefulness of water-supply-pipe used of water system is the multiple tube of galvanized iron conduit, plastic tube or metal and plastics.Galvanized iron conduit is subject to the corrosion of chlorine in the water, generates zinc chloride, and iron gets rusty and causes water pollution and influence service life; Plastic tube is heated, the easy season cracking of influence of light and mechanical factor, leak, and the life-span is short, also has detrimental substance simultaneously, causes the pollution of water quality and environment.Multiple tube also can produce same problem.The interface thread of above-mentioned various water pipes all comes out with the hitch mantle, or the lathe car comes out, and the screw thread of plastic tube casts sometimes, their tube walls are all thicker, allowance is arranged, and light-wall pipe does not have allowance, can only adopt the method for extruding plastic deformation to realize.
Summary of the invention
The preparation method that the purpose of this invention is to provide a kind of plastic stainless steel water pipe joint thread, described plastic stainless steel water pipe joint thread adopts rolled-on method or die pressing to realize that it is characterized in that: the described process of rolling is: (1) gets the plastic stainless steel thin-walled water pipe that wall thickness is 0.3mm～1mm; (2) core: the end at the hard rod iron processes the screw thread that desire is suppressed, and the core external diameter matches with the thin-wall stainless steel bore; (3) will roll die head is fixed on the machine tool; (4) core is inserted in the thin-wall stainless steel pipe, and be fixed on the rolling between the head of machine tool, roll the thread groove that head is aimed at core; (5) the startup lathe rotates core and thin-wall stainless steel together, and gradation strengthens the pressure that rolls head gradually, makes light-wall pipe produce plastic deformation, screw thread uniform interface screw thread on final formation and the core.
The described pressure that rolls on the head is 0.5～2 ton.
The screw thread that rolls at described plastic stainless steel water pipe two ends is 20-60mm, or the plastic stainless steel water pipe of 1M length is rolled into screwed pipe entirely, as cutting the connection short tube.
Described die pressing is to be formpiston with the core, the die sleeve of making to be divided into two lobes in addition is a former, its process is that core is inserted in the light-wall pipe, and die sleeve is enclosed within the light-wall pipe outside, adjusts the position of matched molds, be fixed on the pressurized equipment, the application of force on die sleeve makes light-wall pipe produce plastic deformation, screw thread accordant interface screw thread on final formation and the core, in mould, rotate core and light-wall pipe at last, the vestige that two halves former gaping of joints stays when eliminating mold pressing on the light-wall pipe screw thread.
The invention has the beneficial effects as follows that the 1. thin-wall stainless steel water pipe inside and outside walls that use are very bright, flow resistance is little, and cleaning does not get rusty easily, and durable in use, the life-span is galvanized pipe, plastic tube 5～10 times.2. the plastic forming hickey all is in factory process, does not need specific purpose tool during construction or according to the caliber size, selects the on-the-spot processing of corresponding instrument for use, and is convenient and swift; Can dismantle, easy to maintenance.3. the cost of material is low, can reclaim usefulness again, and the life-span is long, and relatively economical is good.4. to water nonpollution, environment is good.
Description of drawings

Fig. 2 is the process principle schematic diagram of thin-wall stainless steel water pipe joint thread.
The specific embodiment
The present invention is a kind of preparation method of plastic stainless steel water pipe joint thread.Adopt rolled-on method or die pressing to realize (as shown in Figure 1 and Figure 2), its process of rolling is: (1) gets the plastic stainless steel thin-walled water pipe that wall thickness is 0.3mm～1mm; (2) core: the end at the hard rod iron processes the screw thread 2 that desire is suppressed, and core 3 external diameters match with thin-wall stainless steel 1 internal diameter; (3) will roll die head 3 is fixed on the machine tool; (4) core 3 is inserted in thin-wall stainless steels 1 pipe, and be fixed on the rolling between 4 of machine tool, roll 4 grooves of aiming at the screw thread 2 of cores 3; (5) starting lathe, core 3 and thin-wall stainless steel 1 are rotated together, is under 0.5～2 ton of situation at the pressure that rolls on the head, and gradation strengthens gradually and rolls 4 pressure, makes light-wall pipe produce plastic deformation, final form and core on screw thread uniform interface screw thread.Can roll the 20-60mm screw thread on plastic stainless steel water pipe two ends is, or the plastic stainless steel water pipe that 1M is long is rolled into screwed pipe entirely, as cutting the connection short tube, when constructing at the scene, directly cut the required screwed pipe that differs length of pipe and connect with the long plastic stainless steel water pipe of 1M.Can be during site operation without specific purpose tool, or, select corresponding tool processes for use according to the caliber size, convenient and swift; Can dismantle, easy to maintenance.The cost of material is low, can reclaim usefulness again, and the life-span is long, relatively economical good and. to water nonpollution, environment is good.
Above-mentioned die pressing is to be formpiston with core 3, the die sleeve of making to be divided into two lobes in addition is a former, its process is that core 3 is inserted in the thin-wall stainless steel 1, die sleeve is enclosed within thin-wall stainless steel 1 outside, adjust the position of matched molds, be fixed on the pressurized equipment, the application of force on die sleeve, make thin-wall stainless steel 1 produce plastic deformation, screw thread 2 accordant interface screw threads on final formation and the core 3, in mould, rotate core 3 and thin-wall stainless steel 1 at last, the vestige that two halves former gaping of joints stays when eliminating mold pressing on thin-wall stainless steel 1 screw thread 2.
