Description
Technical field
The utility model relates to the stainless steel pipeline joint construction, and specifically a kind of thin-wall stainless steel pipe ring is pressed joint construction and clamp-press type pipe ring pressing mold tool.
Background technique
Stainless steel waterpipe and connection pipe fitting are " the green tubing of 21st century ", have pollution-free, high strength, long lifetime, water resistance is little, comprehensive cost is low, characteristics such as attractive in appearance, being the desirable substitute products of other class water pipes, also will be the final selection of drinking feedwater piping.The butt joint of stainless steel pipe is adopted usually to top formula card pressing mold tool, top formula card pressing mold tool is made of upper die and lower die, during installation Stainless Steel Tube is inserted the bellmouth pipe fitting to the positioning step position, card press tool with special use pushes simultaneously to the card splenium position of U type groove and U type groove one or both sides, rubber seal seals after being squeezed, contraction deformation in the time of card splenium position pipe fitting and tubing, form hexagonal configuration and play the positioning and fixing effect, the crimping link is particularly important in the installation of stainless steel pipe.Whether crimping puts in place crimp, and whether mould factor such as abrasion deformation, directly influences the sealability and the anti-pulling performance of stainless steel pipe.Sealability is not in place, and pipe fitting leaks water easily, and the anti-pulling performance is not in place, when pipe fitting is is in the end checked and accepted hydraulic pressure test, taken off by the increase of water pressure and pulls out, and produces at last and leaks.
In the prior art, top formula mould mainly is divided into, lower module, the U type tongue that during crimping pipe fitting is equipped with seal ring is placed in the mould U type groove, module vertical tube axis up and down, counterdie upwards applies pressure to the upper and lower mould merging and finishes the card pressure along the pipe fitting diametric(al), and employing will certainly produce on pipe fitting top formula mould crimping stainless steel pipe and extrude the position.And mostly most of situation that pipe fitting take place to leak in the middle of the engineering is to appear at pipe fitting and extrudes the position.Its main cause is the wearing and tearing gradually in the crimping work that repeats of top formula mould, even mould deforms, the deviation of pipe fitting groove spot size in addition, more aggravate pipe fitting and extruded the deterioration at position, when the inwall of extruding the position produces fine gap, seal ring can't enter filling chink, and current are just leaked out by the finedraw place under pressure.Present domestic pipe fitting manufacturer requires crimp to limit its crimping number of times in the middle of engineering is used, and superly keeps crimping number of times mould and just does to scrap processing, changes again.But in actual project installation, assembler's major part is common civilian worker, in case mould exceeds the crimping number of times and produces distortion, it is serious that pipe fitting is extruded the position, can't judge immediately also whether pipe fitting can leak, and finds that just pipeline has leak source when carrying out hydraulic pressure test at last.Pressure does not increase, and checks pipe coupling one by one, changes joint.The progress that has influenced engineering has been wasted manpower and materials simultaneously again.
The model utility content
The purpose of this utility model provides a kind of stainless steel pipe ring and presses joint construction, the pipe fitting crimping do not have extrude wrinkling, guarantee the good contraction of seal ring and reached seal request, the circularity that keeps pipe fitting U type tongue after the crimping, and surface finishment, the anti-pulling position becomes circle by original hexagon simultaneously.Pipe part becomes overall circumferential contact by six original angle contacting, has increased the area of contact of tubing and pipe fitting greatly, has increased friction, and the tension pull out force of pipe part is improved.
The model utility content
The technical solution adopted in the utility model is: the stainless steel pipe ring is pressed joint construction and clamp-press type pipe ring pressing mold tool, comprise Stainless Steel Tube and seal ring, it is characterized in that: wherein Stainless Steel Tube 1 termination reaming, Stainless Steel Tube 2 termination fitting tight circles 3 wherein, reaming position, Stainless Steel Tube 1 termination is sleeved on the position of Stainless Steel Tube 2 terminations and fitting tight circle 3, by clamp-press type pipe ring pressing mold tool extruding butt joint, constitute the overall circumferential contact joint construction that Stainless Steel Tube 1 suit coats Stainless Steel Tube 2 and Stainless Steel Tube 2 termination fitting tight circles 3.
Described clamp-press type pipe ring pressing mold tool is made of an extruding cover half group movable extrusion mold group identical with two, two ends in extruding cover half group constitute isometrical annular cover with one heart by contiguous block and the mutually hinged movable extrusion mold group of bearing pin, the extruding cover half group movable extrusion mold group identical with two is evenly distributed on annular and puts, and respectively accounts for 120 ° of circumferencial direction; Extruding cover half group is made of cover half, cover half compressed tablet, locating stud, contiguous block and bearing pin, and the interior ring that the cover half compressed tablet is assemblied in cover half is linked together by locating stud, and cover half two assembling contiguous block is hinged by bearing pin; Described movable extrusion mold group is made of dynamic model, dynamic model compressed tablet, locating stud, Returnning spring, bearing pin, dynamic model compressed tablet and Returnning spring are assemblied on the interior ring of dynamic model by the locating stud location, and an end of dynamic model is hinged with the contiguous block and the bearing pin of extruding cover half group.
The beneficial effects of the utility model: owing to adopt above-mentioned structure, not only avoided in the prior art problem, the problem includes: extrude wrinkling problem, guarantee the good contraction of seal ring and reached seal request, keep the circularity and the surface finishment of pipe fitting U type bulge loop after the crimping, the anti-pulling position becomes circle by original hexagon simultaneously.Increased the area of contact of tubing and pipe fitting greatly, increased friction, the tension pull out force of pipe part is improved; And pipe fitting butt joint is convenient, reduces operating expenses and duration greatly, is not afraid of temperature variation and the expansion that causes, never leaks, and reaches working life more than 50 years, can be synchronous with building.Of the present utility modelly be widely used in industry and civil building stainless steel feedwater piping butt joint, reach save time, convenient, fast, need not professional assembler, whose installation of can doing it yourself by the indication of operation instruction, and solid and reliable should vigorously promote the use.
