B, make expanded view according to front view on material at model;
C, being the center of circle with the O point in expanded view, is radius with OA, and the camber line AFA ' that draws forms technology feed supplement part between the actual evolute ABA ' of camber line AFA ' and osculum;
D, cut the expanded view of band feed supplement part, make model, be tiled in used steel plate on number material;
E, cut off model feed supplement part, aiming at the sideline on number honest material, the actual evolute ABA ' of the osculum that draws;
Actual line, the feed supplement line of f, steel plate number material are all drawn a design and are dashed;
G, the outline line blanking of pressing band feed supplement part number material;
H, utilize veneer reeling machine to roll by rolling positive cone shell side formula, welding is check also.
I, utilize in the big end arc measuring model on veneer reeling machine conical shell to be proofreaied and correct, it is qualified that model camber line and large end face inner arc contact entirely;
J, press the blanking of osculum actual line sample and remove the feed supplement part, finish the making of eccentric cone shell.
Arc measuring model in the described big end, its arc diameter are for will make the big end actual inner diameter of eccentric cone shell, and its chord length L equals to make 1/6 length of the big end actual inner diameter of eccentric cone shell, and is not less than 300mm.
Described veneer reeling machine adopts three rolls plate bending machine.
The present invention utilizes three rolls plate bending machine to roll eccentric cone shell, makes front view, vertical view, the expanded view of required eccentric cone shell on request.Utilize three rolls plate bending machine to roll by the method that rolls positive conical shell; This moment, the conical shell large end face was an ellipse, utilized the interior arc measuring model of big end on three rolls plate bending machine conical shell to be proofreaied and correct, and it is a circular end surface that large end face is proofreaied and correct, and cuts off the feed supplement part after the correction, can get eccentric cone shell.
Beneficial effect of the present invention: utilize three rolls plate bending machine just can process the eccentric cone shell of different size, the production efficiency height, highly versatile has reduced investment, has saved production cost, and labour intensity is little.

(AFA ' BA dash area among the AFB among Fig. 1 and Fig. 3 is technology feed supplement part;
CDE and C ' DE ' dash area are used for illustrative purposes only among Fig. 3, and the actual fabrication process does not have this part)
The specific embodiment
The present invention utilizes three rolls plate bending machine to roll out AFDC (Fig. 1, Fig. 2, shown in AFDE be that a positive conical shell and AFA ' E ' DE shown in Figure 3 are a positive conical shell expanded view) by the method that rolls positive conical shell; This moment, the conical shell large end face was an ellipse, utilized arc measuring model in the big end, as shown in Figure 4, on three rolls plate bending machine conical shell was proofreaied and correct, and it is a circular end surface that large end face is proofreaied and correct; Cut off the AFB part after the correction, can get eccentric cone shell ABDC.
The present invention all is suitable for the eccentric cone shell of different angles.
The concrete implementation step of the present invention is as described below:
(1), by making eccentric cone shell neutral line size draw front view, i.e. ABDC part among Fig. 1.Its vertical view that also can draw as shown in Figure 2, among Fig. 2 is that the circle of diameter is the eccentric cone shell upper surface with AB, and the circle that with CD is diameter is the eccentric cone shell lower surface.Dash area only is the usefulness of explanation among Fig. 1,2, and reality can not drawn.So-called neutral line promptly is the intermediate layer that material refers to material size constancy after bending.
(2), make expanded view according to front view, vertical view at malthoid or other model on material, as shown in Figure 3.
