Abstract
The utility model discloses an eccentric rolling cone flaring die, which is applied in the flaring of a take-over opening of a bellmouthing of a machine connecting tube of an inner machine and an outer machine of an air conditioner. Two inclined cone bodies which are larger a semicircle cone body are symmetrically combined and are installed and fixedly sheathed on a fixing sleeve seat, which constitutes a double eccentric rolling cone. The technology distance between two cone tips of the rolling cone is the technical key of a flaring bellmouthing. Under a fixing sleeve, a seat surface is provided with a clamping handle. The utility model can be used on a machine drilling press. The low speed rotation of the utility model makes a tube opening rotated to reach the uniformity, the flatness, no burr, no spalling hemming of the bellmouthing. The utility model ensures the tight and reliable sealing of the take-over opening.
Description
The utility model discloses a kind of instrument, especially a kind of eccentric tapper enlarging mould, it belongs to air-conditioner mounting technique field.
Existing detachable air conditioner, the machine pipe of its inside and outside machine all adopt horn mouth to connect.This flared joint is higher to bell-mouthed quality requirement: its enlarging attenuate amount is wanted suitably evenly, and the loudspeaker mouth of pipe is smooth, first burr, no raw edges, no flanging.Yet traditional enlarging mode is to adopt 90 degree circular cones to develop or 90 degree triangular pyramid rotary-cut enlargings.This enlarging mode can cause the enlarging decrement bigger, and mouth of pipe burr is many, easy flanging, and mouthful wall thickness is inhomogeneous, easily raw edges.Wherein key is: the drawback of enlarging mould own causes.
The purpose of this utility model is that a kind of novel enlarging mould will be provided.This eccentric cylinder enlarging mould is structurally simple, and convenient in the use, the enlarging effect will reach: the horn mouth wall thickness is even, and is smooth, and the attenuate amount suitably reduces, the connecting leg good sealing effect.
Task of the present utility model has following technical scheme to finish, be developed into a kind of eccentric tapper enlarging mould, on the upper bottom surface of fixing block set, be fixed with two inclined to one side cones and be combined into two eccentric tapper bodies symmetrically greater than the semicircle cone, the plane that two inclined to one side cones combine is parallel to the awl height of two inclined to one side cones respectively, the associated splice line that is formed by two these inclined to one side cones combinations on this plane is parabola shaped, the vertex of a cone of this parabolical summit and two these inclined to one side cones line and extended line thereof between the mid point of suitable distance are: the central symmetry axis of this tapper body, also be provided with grip shank at the fixing bottom surface of block set, the axis of this handle promptly overlaps with this central symmetry axis.
This eccentric tapper enlarging mould, the vertex of a cone of described two inclined to one side cones is at a distance of suitable distance, and its span is at 0.4～6.0mm.
This eccentric tapper enlarging mould, described two inclined to one side cones, its cone-apex angle is 30～90 degree.
Enlarging mould of the present utility model, its advantage is: owing to the eccentric tapper body that inclined to one side cone was combined into that has designed by two large semicircle cones, line up carries out roll extrusion and squeezes the spread mouth.Because this tapper body low speed rotation is carried out the roll extrusion of symmetry to the motionless copper pipe mouth of clamping, make tube wall stressed evenly, its extension amplitude unanimity, and the defect that can not produce burr and became uneven.Two inclined to one side cones of this tapper body can adopt line cutting technology that normal cone is made inclined to one side cone greater than half-conical, and by fixing block set two inclined to one side cones being combined becomes two eccentric tapper bodies again.Its manufacturing process is simple, and production cost is lower, is the indispensable instrument in air-conditioner mounting technique field.
Embodiment of the present utility model further describes as follows in conjunction with the accompanying drawings, as shown in the figure:
Fig. 1 is the structural front view of eccentric tapper enlarging mould.
Fig. 2 is the structure vertical view of eccentric tapper enlarging mould.
One piece of eccentric tapper enlarging mould making, fixedly block set 2 hot charging cover on upper bottom surface is intrinsic is combined into two eccentric tapper bodies symmetrically by two inclined to one side cones 1 greater than the semicircle cone for it.The plane that these two inclined to one side cones 1 combine is parallel to the awl height of two inclined to one side cones 1 respectively, on this plane by two these inclined to one side cones 1 in conjunction with and the associated splice line 3 that forms is parabola shaped.The vertex of a cone 5 of this parabolical summit and two these inclined to one side cones 1 is at a distance of the central symmetry axis that suitably is this tapper body apart from line and extended line thereof between the mid point of e.Also be provided with grip shank 4 at the fixing bottom surface of block set 2, the axis of this handle 4 promptly overlaps with this central symmetry axis.
The cone-apex angle of the inclined to one side cone 1 of this eccentric tapper enlarging mould is 90 degree, and the vertex of a cone 5 of two inclined to one side cones 1 is 3.5mm apart from e suitably apart.
Claims (3)
1, a kind of eccentric tapper enlarging mould, it is characterized in that: on the upper bottom surface of fixing block set, be fixed with two inclined to one side cones and be combined into two eccentric tapper bodies symmetrically greater than the semicircle cone, the plane that two inclined to one side cones combine is parallel to the awl height of two inclined to one side cones respectively, the associated splice line that is formed by two these inclined to one side cones combinations on this plane is parabola shaped, the vertex of a cone of this parabolical summit and two these inclined to one side cones line and extended line thereof between the mid point of suitable distance are: the central symmetry axis of this tapper body, also be provided with grip shank at the fixing bottom surface of block set, the axis of this handle promptly overlaps with this central symmetry axis.
