Abstract
The utility model relates to a forming mold used to manufacture the bottom of a steel air bottle. The forming mold used to manufacture the bottom of the steel air bottle comprises a mold sleeve connected with a base seat of a press, wherein a convex mold used for forming the bottle bottom is arranged inside the mold sleeve, and the convex mold is matched with a punch connected with a press head of the press. The forming mold used to manufacture the bottom of the steel air bottle is characterized in that the convex mold is provided with a cut-sphere-shaped forming convex face, an annular plane is in smooth transition connection with the periphery of the cut-sphere-shaped forming convex face, the punch is provided with a cut-sphere-shaped forming concave face which is correspondingly matched with the convex mold, and an annular arc surface is in smooth transition connection with the periphery of the cut-sphere-shaped forming concave face. The forming mold used to manufacture the bottom of the steel air bottle has the advantages that the bottle bottom which is sealed in a spinning mode is formed for the second time through the punch and the convex mold, so that the bottle bottom is even in thickness, natural in transition and stable when touching the ground; relevant design standards of the air bottle are met; the punch is provided with a process hole, so that the installation and replacement of the punch are convenient; and the convex mold is in threaded connection with the mold sleeve, so that the installation and replacement of the convex mold are convenient.
Description
Technical field
The utility model relates to the pressure vessel manufacturing installation, and is especially a kind of for the manufacture of the finishing die at the bottom of the steel gas bottle bottle.
Background technology
Steel gas bottle is commonly used to splendid attire permanent gas, liquid gas or mist, it is a kind of pressure resistant vessel, adopt seamless steel pipe two ends local heat in the existing manufacture method, make gas cylinder by spinning, closing in, this manufacture method when being shaped at the bottom of the bottle at the bottom of the bottle size Control relatively more difficult, the wall ratio cylindrical shell wall thickness of gas cylinder bottom is wanted more than the thick twice, and barrel and bottle end transition will meet the relevant design standard of gas cylinder, and transition nature and dimensional requirement are strict.
The utility model content
Of the present utility model is exactly wayward for size at the bottom of solving the spinning bottle, can not satisfy the design standard of gas cylinder, and provide a kind of for the manufacture of the finishing die at the bottom of the steel gas bottle bottle, to carrying out secondary forming at the bottom of the bottle, forms the bottle end of satisfying standard.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of for the manufacture of the finishing die at the bottom of the steel gas bottle bottle, comprise the die sleeve that is connected with the press base, be provided with the punch that is shaped at the bottom of the bottle in the die sleeve, described punch cooperates with a drift that is connected on the press pressure head, it is characterized in that: described punch has a segment shape shaping convex surface, along the planar annular that has a rounding off connection segment shape shaping one week of convex surface, described drift has a segment shape shaping concave surface with the punch corresponding matching, along the annular cambered surface that has a rounding off connection segment shape shaping one week of concave surface, the neighboring of annular cambered surface is connected with the outside cylinder side face rounding off of drift.
On the basis of above-mentioned main technical schemes, can increase following further perfect technical scheme:
Greater than 50mm, to be a radius form greater than the round-corner transition of 18mm described annular cambered surface described drift concave surface apart from the cup depth of annular cambered surface peak.
One group of fabrication hole evenly distributes on the outside cylinder side face of described drift.
Described die sleeve has the annular thin wall that cooperates with the external cylindrical surface of drift, and the die sleeve bottom in annular thin wall has threaded connection hole, and described punch bottom has the axle that is threaded that matches, and the connecting axle end face is provided with the interconnecting hole that usefulness is installed.
The beneficial effects of the utility model are by drift and punch secondary forming to be carried out at the bottle end of spinning, form at the bottom of making bottle that wall thickness is even, transition nature, ground connection be stable; Satisfy the relevant design standard of gas cylinder; Drift is provided with fabrication hole, makes things convenient for the installation of drift to change; Punch and die sleeve are threaded connection, and make things convenient for the installation of punch to change.
Below in conjunction with drawings and Examples the utility model is further specified.
Description of drawings
Fig. 1 is embodiment front view of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model is a kind of for the manufacture of the finishing die at the bottom of the steel gas bottle bottle, comprise the die sleeve 1 that is connected with the press base, die sleeve 1 inner bottom part is the circular cavity of a placement punch, has an end above the circular cavity along the axially extended annular thin wall 12 of die sleeve, the outer bottom of die sleeve 1 has outstanding platform, platform is provided with screwed hole 11, screwed hole 11 axially runs through the die sleeve bottom and links with circular cavity, the bottom outer peripheral face of die sleeve 1 has annular flange, one group of counterbore evenly distributes on the flange, be provided with the punch 2 that is shaped at the bottom of the bottle in the die sleeve 1, described punch 2 bottoms have the axle 22 that is threaded that matches, the axle 22 that is threaded axially arranges, connecting axle 22 end faces are provided with the interconnecting hole 21 that is used for installation of axial placement, described interconnecting hole 21 can adopt interior hexagonal connecting hole, also can adopt interior four jiaos of connecting holes, can also adopt interior triangle joint hole, mainly be to make things convenient for punch 2 to be installed in the die sleeve 1, has a segment shape shaping convex surface 24 on the described punch 2, the centre of sphere of segment shape shaping convex surface 24 is positioned on the axis of punch 2, the planar annular 23 that a rounding off connects that has in a week along segment shape shaping convex surface 24, described planar annular 23 is preferably the annular plane, when punch 2 is placed in the circular cavity of die sleeve 1, punch 2 and die sleeve 1 thin-walled forming shaped die cavity;
Described punch 2 cooperates with a drift 3 that is connected on the press pressure head, described drift 3 has a segment shape shaping concave surface 31 with punch 2 corresponding matching, the centre of sphere of segment shape shaping concave surface 31 is positioned on the axis of punch, along the annular cambered surface 32 that has a rounding off connection segment shape shaping 31 1 weeks of concave surface, the neighboring of annular cambered surface 32 is connected with the outside cylinder side face rounding off of drift 3, described drift 3 concave surfaces apart from the cup depth of annular cambered surface peak greater than 50mm, to be a radius form greater than the round-corner transition of 18mm described annular cambered surface 32, one group of fabrication hole 33 evenly distributes on the outside cylinder side face of drift 3, described fabrication hole 33 is preferably three, makes things convenient for the installation of drift 3 to change.
