Description
Technical field:
The present invention relates to a kind of nonmetal filled media of making the branch pipe tee connection accessory and with the manufacturing process of its extruded piping branch tee, can make important pipe fittings such as copper threeway, steel threeway and stainless steel threeway, can be widely used in the pipeline engineering system of refrigeration industry, building trade and industries such as chemical industry and food.
Background technology:
Threeway is a pipe fitting important in the pipeline engineering, and because of its purposes is wide, the industry face width is subjected to showing great attention to of numerous manufacturers, the manufacturing patent that is caused by threeway is also particularly various; Technological approaches roughly is divided into hot and cold extruding two big classes, wherein with cold extruding technique cheaply with fastest developing speed (the hot extrusion development more slowly and part be eliminated, this does not give unnecessary details), derive plumbous extruding (based on the production of copper threeway), oiling (or water) the extruding technology such as (to produce the steel threeway) of irritating again from cold extrusion.
In known extrusion technique, the physical dimension of irritating plumbous extruded piping branch tee is best, and cost is minimum, but exists the lead contamination problem; The threeway length obviously not enough (the particularly thin-walled mini three links of φ 9.53 following specifications) of oiling (or water) extruding, it is slower to be difficult to reach the length and the work efficiency of irritating plumbous extruding, so existing technology is still most widely used to irritate plumbous cold extrusion.
In 2005, state such as European Union and Japan issued in the threeway manufacture process must not leading instruction, for effectively solving the lead contamination problem, the new technology that " the copper three-way pipe " by name of number of patent application 200520147320.6 occurred, the essence of its manufacturing process is " unleaded extruding+soldering ", and production cost is higher relatively.Especially at refrigeration industry, because of there not being suitable substitute technology cheaply, irritate the mainstream technology that plumbous extruding is still made for the copper threeway so far, the deleading that manufacturer's emphasis reply is irritated behind the plumbous extruded piping branch tee is totally spent, and lead contamination is left for oneself employee and factory, stay the big ground of China.
Summary of the invention:
The objective of the invention is to solve the deficiencies in the prior art, provide a kind of can exempt the pollution of heavy metals such as lead, again can than irritate plumbous extruding cost lower, also can be with extruding with the expanded range of material to the nonmetal filled media of the threeway manufacturing usefulness of multiple high-ductility materials such as copper, iron, mild steel, stainless steel and utilize the manufacturing process of this medium manufacturing threeway.
For achieving the above object, technical scheme provided by the invention is:
A kind of nonmetal filled media of making the branch pipe tee connection accessory, this filling medium is a kind of mixed uniformly nonmetallic powder material, it is by talcum powder H
2Mg
3(sio
3)
4, Nacl NaCl and urea (NH
2)
2Three kinds of powder constituents of CO, and evenly mix by 5～25%, 95～50% and 0～25% mass ratio respectively.
The compatibility mechanism of non-metal powder filling medium involved in the present invention is: component Nacl NaCl is a main material, is used for directly extruding and transmits extruding force, forces to be installed in the straight pipe distortion on request under normal temperature in the mould; Component talcum powder H
2M g
3(sio
3)
4Effect be that the roughness of protection three-way tube wall and the crystal gap of filling Nacl NaCl are to transmit extruding force; Component urea (NH
2)
2The main effect of CO is to meet high temperature and volatilize in annealing operation, abdicates the space and makes other two kinds of components become comparatively loose and be easy to the mechanical-moulded of back operation.
The main technique flow process of threeway extruding involved in the present invention includes: the powder medium → pickling → oven dry → packing of blanking → straight pipe filling powder medium → cold extrusion → annealing → mechanical-moulded → stripping filling.
In this technological process, if the part of desire processing is threeway series (the T type pipe of T-shape, see Fig. 1), its main technique flow process is: the powder medium → pickling → oven dry → packing of blanking → straight pipe filling powder medium → cold extrusion → stripping filling gets final product, and it is filled a prescription by talcum powder H
2Mg
3(sio
3)
4With two kinds of powder constituents of Nacl NaCl, and evenly mix by 5～25% and 95～75% mass ratio respectively.
If the part of desire processing is top logical series (Y-piece, see Fig. 2) or the logical series of side (L type pipe, see Fig. 3) or the trident series (Y-pipe of " shank " type, see Fig. 4) or special-shaped extrusion series three-way pipe (see figure 5), then the main technique flow process is: the powder medium → pickling → oven dry → packing of blanking → straight pipe filling powder medium → cold extrusion → annealing → mechanical-moulded → stripping filling; Its prescription is by talcum powder H
2Mg
3(sio
3)
4, Nacl NaCl and urea (NH
2)
2Three kinds of powder constituents of CO, and evenly mix by 5～25%, 95～50% and 0～25% mass ratio respectively.
In the technology of the plumbous extruded piping branch tee of known traditional filling, when the part of processing led to the three-way pipe of series or the logical series of side or trident series or special-shaped extrusion series for the top, its main technique flow process is: blanking → straight pipe was irritated lead → cold extrusion → deleading → annealing → T type pipe and is irritated lead → mechanical-moulded → deleading → deleading → pickling → oven dry → packing; Comparing with main technique flow process of the present invention, is twice filling lead, many " it is plumbous that T type pipe is irritated ", " deleading " and " deleading " three process, and production cost is higher relatively.
Threeway extruding involved in the present invention when extruding is two-way offset mode, can extrude threeway, four-way multi-way pipe fittings such as (seeing Fig. 1～6); When extruding is unidirectional mode or quadrature impact extrusion pattern, then can extrude the elbow (see figure 7).
The extruding of threeway involved in the present invention is copper, iron, mild steel, cold extrusion with multiple high-ductility materials such as stainless steels with the scope of material, thereby can push manufactured copper threeway, iron threeway, mild steel threeway and stainless steel threeway etc.
The manufacturing process of the plumbous extruded piping branch tee of traditional filling, under the prerequisite of not considering lead contamination, be well suited for pushing the copper threeway, but, filling medium " lead " is the soft metal of a kind of low melting point (327.4 ℃), when irritating the threeway of plumbous extruding iron, mild steel threeway and stainless steel threeway, the threeway length of extruding is also shorter, is difficult to reach the length of powder extruding.
Therefore, the manufacturing process of a kind of nonmetal medium extruded piping branch tee involved in the present invention, its technical advantage is obvious, can satisfy the promulgation of states such as European Union and Japan must not leading in the threeway manufacture process command request, exempted the plumbous pollution that waits heavy metal fully, again can plumbous extruding cost be lower, longer than the threeway length of oiling (or water) extruding, work efficiency is higher, also can extruding make the field with the expanded range of material to the extruding of multiple high-ductility materials such as copper, iron, mild steel, stainless steel than irritating.
