Abstract
The invention discloses a die for tube upsetting flange forming, and belongs to the technical field of flange forming. The technical scheme provided by the invention is that the die for tube upsetting flange forming is characterized in that the die comprises a convex die fixing plate, a convex die unit and a concave die sleeve; the convex die fixing plate is fixedly arranged above the convex die unit; the concave die sleeve is internally provided with a cavity; and a sleeve is disposed inside the cavity of the concave die sleeve in an encircling manner. The beneficial effects of the die are that the concave die has a combined structure, so that the strength of the die can be improved, and the die is convenient to dismount; and a core rod has a positioning effect, can prevent tube wall metal from flowing in the internal diameter direction, and enables the tube wall metal to fill in the external diameter direction.
Description
Technical field
The present invention relates to a kind of mould for Flange Forming by Upsetting-forging Tube, belong to Flange Forming technical field.
Background technology
Flange joint especially tube flange owing to there is good intensity and compactness and being widely used in the fields such as metallurgy, oil, chemical industry and pipe production.Tube flange forming technology mainly contains two kinds: welding procedure and Forging Technology.Welding procedure is restricted because the reasons such as crevice corrosion, stress corrosion and welding deformation make it apply.And forge monolithic molding flange arrangement and both simplified technique and turn avoid welded shortcoming.
Summary of the invention
The object of this invention is to provide a kind of mould for Flange Forming by Upsetting-forging Tube.The present invention adopts following technical scheme: a kind of mould for Flange Forming by Upsetting-forging Tube, it is characterized in that, comprise: punch retainer, punch, die case, described punch retainer is fixedly installed on the top of described punch, described die case inside has cavity, and the cavity inside of described die case is surrounded with sleeve.
Preferably, sleeve inner is provided with blank, and blank inside is provided with plug.
Preferably, the lower cavity of die case is surrounded with gasket ring.
Preferably, gasket ring inside is surrounded with packing ring.
Preferably, punch retainer is connected by screw with punch.
Preferably, punch is connected by screw with plug.
The beneficial effect that the present invention reaches: die adopts combining structure, also can improve the intensity of mould, convenient disassembly simultaneously; Plug not only plays positioning action, and can limit tube wall metal filling to the outer direction to internal diameter direction flowing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The implication marked in figure: 1-punch retainer, 2-punch, 3-blank, 4-die case, 5-gasket ring, 6-packing ring, 7-sleeve, 8-plug, 9-screw.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1 be structural representation of the present invention, the present invention proposes a kind of mould for Flange Forming by Upsetting-forging Tube, comprising: 1-punch retainer, 2-punch, 3-blank, 4-die case, 5-gasket ring, 6-packing ring, 7-sleeve, 8-plug, 9-screw, punch retainer 1 is fixedly installed on the top of punch 2, and die case 4 inside has cavity, and the cavity inside of die case 4 is surrounded with sleeve 7.
Sleeve 7 inside is provided with blank 3, and blank 3 inside is provided with plug 8; The lower cavity of die case 4 is surrounded with gasket ring 5; Gasket ring 5 inside is surrounded with packing ring 6; Punch retainer 1 is connected by screw 9 with punch 2; Punch 2 is connected by screw 9 with plug 8.
The beneficial effect that the present invention reaches: die adopts combining structure, also can improve the intensity of mould, convenient disassembly simultaneously; Plug not only plays positioning action, and can limit tube wall metal filling to the outer direction to internal diameter direction flowing.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
