The specific embodiment
Referring to Fig. 1, in the present embodiment, the stainless steel enclosure wall tube is formed (referring to picture) by internal layer-carbon steel layer 36 and skin-stainless steel cladding 35.Skin-stainless steel cladding is wrapped in the outer surface of carbon steel layer, thereby plays rust inhibition, and glossy.This cladding steel pipe is because very hard, and skin is very crisp again, and existing technology can not be processed into reducing.Stainless steel cladding reducing pipe is made up of two parts, and right-hand component is a steel tube body 1, and the left side is a reducing part 2.The outside dimension of reducing part is less than the outside dimension of steel tube body 1, but greater than the internal diameter size of steel tube body 1.The length of reducing part 2 can be used and the external diameter of pipe is decided according to actual.
Fig. 2 is the die drawing of the reducing part 2 of the processing stainless steel cladding draw.This mould is a columnar mould, and the external diameter of its internal diameter size d and reducing part 2 is suitable, and length is greater than the length of reducing part 2.
Fig. 3 is the partial enlarged drawing of the oral area of mould shown in Figure 2.As shown in the figure, this mould has a hole, and the oral area in hole has three parts: import oral area 31, arc choke 32 and pressing mold processing part 33.Importing oral area 31 is that an end that will be used to the cladding steel pipe need be processed enters in the mould easily.Arc choke 32 is importing between oral area 31 and the pressing mold processing part 33, mainly be to make the processing part of stainless steel cladding steel pipe can enter into pressing mold processing part 33 smoothly, it is non-circular that the cladding steel pipe too is deformed to, and loses the function of cladding steel pipe, perhaps breaks.Unprocessed stainless steel cladding steel pipe since the effect of external force progressively enter and enter pressing mold again behind the arc choke 32 and add the Ministry of worker 33 from importing oral area 31, divide quite in choke to be processed because the internal diameter of pressing mold processing part is d, thereby the cladding steel pipe enters the reducing part that will form corresponding size behind this pressing mold processing part 33.
Below with reference to Fig. 4 processing method of the present invention and process equipment are elaborated.An embodiment of process equipment of the present invention comprises and clamping with cylinder 41, moving folder watts 43, fixed folder watts 45, slide block 46, mould 47, draw cylinder 48 and support 42.Clamp and to form a clamping device with cylinder 41, moving folder watts 43 and fixed folder watts 45 and be used for making the reducing of cladding steel pipe to add keeping cladding steel pipe man-hour and fix.As shown in the figure, fixed folder watts 45 Shang watt 245 and following watt 145 two-part inner chamber form the hole of a circle, diameter is suitable in the external diameter that clads steel pipe.Shang watt 245 be connected with the piston that clamps with cylinder 41, following watt 145 is fixing, its semicircular inner chamber is used for placing and clads steel pipe.Moving folder watts 43 comprises the inner chamber of a semicircle, and slightly larger in diameter is in the external diameter of cladding steel pipe, and when it contacted with the cladding steel pipe, cladding steel pipe can not be completely fixed, and only plays preliminary positioning action.When clamping piston with cylinder 41 and move down, be connected with piston decide folder watts 45 Shang watt 245 move downward, clamp the cladding steel pipe with following watt 145 semicircle inner chamber.At the left end of process equipment, draw cylinder 48 is formed Powerpush Units with slide block 46, promotes processing mold and moves right, and what make that the vertical wall body c of cladding steel pipe 44 left ends will be processed into reducing is partially submerged into mould 47.As shown in the figure, slide block 46 links to each other with the piston of draw cylinder 48.Slide block 46 can be along guide rail 49 move left and right that are arranged on base 42.Mould 47 can be positioned on the slide block 46.Its inner chamber axis with fixing after the axis of cladding steel pipe consistent.When slide block 46 moves right under the promotion of draw cylinder 48, so promoting mould 47, the vertical wall body c of left end moves right together, thereby the left end of cladding steel pipe 44 can be gradually entered and is entered pressing mold processing part 33 through arc reducing part 32 recited above by the introducing port 31 of mould like this, and reaches certain degree of depth.So, because the internal diameter size d of the pressing mold processing part 33 of mould is less than the outside dimension of cladding steel pipe, and suitable, clads the part that steel pipe enters the inner chamber of mould like this and just formed the reducing part with the size of needed reducing part.
