Abstract
The invention relates to the technical field of metal plastic forming machines, in particular to a spinning wheel for machining a flange. The spinning wheel is provided with a wheel body and is characterized in that the upper end surface of the wheel body is provided with flange forming arch surfaces gradually extending in an arc outward mode from the axis center to the outer edge, so that the effects that the spinning wheel body and the wind tunnel flange are kept in point contact all the time in the spinning process, and the side line of the flange is obviously flat in the forming process are guaranteed; a springback surface of the flange adopts the flange forming arch surfaces, so that the effect that the flange subjected to spinning bounds back to the horizontal position is guaranteed; and the two flange forming arch surfaces are connected through a transition arc, so that a connecting arc for a wind tunnel forming surface and a flange forming surface is automatically formed. The spinning wheel has the advantages of being simple in structure, high in machining accuracy, high in work efficiency, attractive in appearance and the like.
Description
Technical field
The present invention relates to metal plastic forming field of mechanical technique, specifically a kind of flange processing spinning wheel.
Background technology
It is known that, air duct is by air duct molding surface, Flange Plane is formed, traditional air duct is when spinning, usually with lower spinning wheel and upper spinning wheel, the flange of air duct is carried out plasticity rotary pressure deformation, above-mentioned lower spinning wheel is normally made up of upper transverse plane and lower end cone, and described lower spinning wheel two ends are connected by round-corner transition respectively, so that the flange forming face being spun to is steadily smooth, described lower spinning wheel upper surface must be perpendicular to lower spinning wheel medullary ray, described lower spinning wheel center is provided with open holes, its deficiency is: when Flange Plane is carried out plastic making, owing to the upper surface of lower spinning wheel is perpendicular to lower spinning wheel medullary ray, in plastic forming process, lower spinning wheel and air duct are three-point contact, a bit with on air duct flange concurrent is taken turns in the middle of wherein, other 2 contact with air duct flange, progressively increase from inside to outside with flange relative position, and 2, outer end distance progressively increases, and intermediate point and flange relative position reduce gradually, air duct end face of flange is thus caused to present flange resilience face, air duct flange is caused to be arc shape, the plane being perpendicular to air duct medullary ray cannot be reached, make the planeness of air duct flange defective.
At present, in spinning process, produce resilience to solve flange face, usually behind the flange forming face of the complete air duct of spinning, more artificial shaping, air duct Flange Plane is struck flat. Its deficiency is: process shaping operation inconvenience loaded down with trivial details, artificial, inefficiency, work pieces process precision low.
Summary of the invention
It is an object of the invention to solve above-mentioned the deficiencies in the prior art, it is provided that the flange processing spinning wheel that a kind of structure is simple, working accuracy height, working efficiency are high.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of flange processing spinning wheel, it is provided with wheel body, it is characterized in that described wheel body upper surface is provided with by axle center to outer rim curved outward extending flange forming arch face gradually, to ensure that spinning wheel body and air duct flange keep being in point cantact all the time in spinning process, when ensureing flange forming, sideline is obviously smooth; Flange resilience face, by adopting flange forming arch face, ensure that spinning rear flange springs back to level attitude, and two flange forming arch faces are through transition circular sliding slopes, is beneficial to automatically be formed the connection circular arc in air duct molding surface and flange forming face.
The present invention can be respectively equipped with by axle center to the outer rim flange forming arch face that curved relative extension is drawn close gradually in described wheel body upper surface with lower surface, be beneficial to the upper and lower ends flange forming face to air duct and process, it is to increase working efficiency.
The cambered surface angle of the flange forming arch face of wheel body of the present invention is between 15 °-30 °, and the radius of described transition arc is between 100mm-400mm.
The present invention, owing to adopting said structure, has the advantages such as structure is simple, working accuracy height, working efficiency high profile are attractive in appearance.

Embodiment
Below in conjunction with accompanying drawing, the present invention is further described:
As shown in drawings, a kind of flange processing spinning wheel, it is provided with wheel body, it is characterized in that described wheel body upper surface is provided with by axle center to outer rim curved outward extending flange forming arch face 1 gradually, or, also can being respectively equipped with by axle center to the outer rim flange forming arch face 1 that curved relative extension is drawn close gradually with lower surface in described wheel body upper surface, to ensure that spinning wheel body 2 and air duct flange 3 keep being in point cantact all the time in spinning process, when ensureing flange forming, sideline be obviously smooth; Flange resilience face, by adopting flange forming arch face 1, ensure that spinning rear flange springs back to level attitude, and two flange forming arch faces 1 are through transition circular sliding slopes, is beneficial to automatically form the connection circular arc of air duct molding surface 1 with flange forming face.
The present invention is when spinning, process spinning wheel end face due to flange and it is designed to flange forming arch face 1, spinning wheel 2 and air duct flange 3 spinning process remain and is in point cantact, ensure that flange is smooth, when being worked into flange resilience face, air duct flange is pressed down along with the arc of flange forming arch face, the rotary course of thermoplasticity and high speed centrifugation power make the arc pressed down spring back to level attitude, make air duct and air duct flange once shaped, greatly accelerate process velocity, ensure that processing quality, it is to increase working efficiency.
The present invention is arranged on vertical spinning machine, has the following advantages:
One, do not increase operation, original process carries out process optimization, the basis reaching technique object saves man-hour, it is to increase efficiency;
Two, without the need to transforming more exchange device, on original vertical spinning machine, spinning wheel can be changed, invest little, risk is low, the cycle is short, significantly reduces cost;
Three, take turns on basis that the height with air duct point of contact do not change under ensureing, by under take turns and change point cantact into air duct flange three-point contact, make flange keep smooth in spinning process;
Under take turns and change spherical shape into, by increasing R arc (i.e. flange resilience face), effectively eliminate the phenomenon that flange resilience after rotary press modelling causes flange face injustice.
