Abstract
The utility model discloses a kind of core roller and roll over ring mould, include the supporting plate of ring rolls and disposed thereon, it is characterized in that: this mould comprises core roller, die body, described die body adopts with described core roller and is threaded, described die body is made up of hollow circular cylinder and one-side band cutting edge flange, described band cutting edge flange is set to cone flange, the large end of horn mouth of its cone flange upward, lower surface is gradient, be positioned at cylinder axis to lower end position, described rolling ring mould is arranged on the inner side of annular forging piece.The beneficial effects of the utility model are: core roller, die body are connected by shaft shoulder positioning threads, the simple easy accessibility of structure, for the production of forging special-shape ring, reduce the production cost of forging special-shape ring, improve operating efficiency, simple and practical.
Description
Technical field
The utility model relates to a kind of Ring Rolling Machine, especially relates to a kind of core roller and rolles over ring mould, for the manufacture of forging special-shape ring.
Background technology
At present,--heating--cogging--heat treatment that heating--rolles over ring--that prior art is, in processing annular forging piece product, the main production process of large-scale wind electricity flange is: the blanking of circle base, wherein rolling over ring is forging blank forming process, rolles over the operation principle schematic diagram of ring see Fig. 1.During rolling, be placed on core roller by ring forging stock, utilize the roll-force between ring rolling machine main roll and core roller that ring wall thickness is compressed, metal tangentially direction extends, thus realizes ring diameter and constantly expand.When making blank, if do not apply mould, then can only roll over square-section processed blank by shown in Fig. 1.Its shortcoming is: one is waste raw material, and two are the increase in mach workload, and three is the production cycles extending flange.This is the deficiencies in the prior art parts.
Summary of the invention
The purpose of this utility model is, overcomes the deficiencies in the prior art, and reduce material consumption, we have installed mould on core roller, provide a kind of cost low, and a kind of core roller that energy resource consumption also significantly reduces rolles over ring mould.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of core roller rolles over ring mould, include the supporting plate of ring rolls and disposed thereon, it is characterized in that: this mould comprises core roller, die body, described die body adopts with described core roller and is threaded, described die body is made up of hollow circular cylinder and one-side band cutting edge flange, described band cutting edge flange is set to cone flange, the large end of horn mouth of its cone flange upward, lower surface is gradient, be positioned at cylinder axis to lower end position, described rolling ring mould is arranged on the inner side of annular forging piece.Mould in use, all will be sleeved on core roller, and roll in ring process, core roller mould forms groove on forging stock inner headed face, thus achieves the object reducing material consumption.As the flange of same size, roll over square-section processed blank, need materials 4995Kg, after the flange mould of application top, actual materials 4410Kg, every part blank can realize few materials 585Kg.
Further improvement of the utility model has, and the top of described core roller arranges the shaft shoulder, and its upper end arranges screw thread.Die body carries out the location of vertical direction by the shaft shoulder, and with being threaded, annular forging piece one end pallet support, the other end is supported by lower cone roller.This rolling ring mould structure is simple, does not need key to be connected, be directly sleeved on the shaft shoulder on core roller between mould with core roller, and height is without the need to adjustment, and then compress with two background nuts, just can come into operation, dismounting is simple.
The structure described is not had to belong to prior art in description.
The beneficial effect of this programme can be learnt according to describing of such scheme, a kind of core roller rolles over ring mould, include the supporting plate of ring rolls and disposed thereon, it is characterized in that: this mould comprises core roller, die body, described die body adopts with described core roller and is threaded, described die body is made up of hollow circular cylinder and one-side band cutting edge flange, described band cutting edge flange is set to cone flange, the large end of horn mouth of its cone flange upward, lower surface is gradient, be positioned at cylinder axis to lower end position, described rolling ring mould is arranged on the inner side of annular forging piece.The beneficial effects of the utility model are: core roller, die body are connected by shaft shoulder positioning threads, the simple easy accessibility of structure, for the production of forging special-shape ring, reduce the production cost of forging special-shape ring, improve operating efficiency, simple and practical.
Accompanying drawing explanation
Fig. 1 is ring rolls operating diagram,
Fig. 2 is the utility model structural representation.
In figure: 1 is home roll, 2 is supporting plates, and 3 is core rollers, and 4 is annular forging pieces, and 5 is cone rollers, and 6 is die bodys, and 7 is nuts.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Can be found out by accompanying drawing, a kind of core roller rolles over ring mould, include the supporting plate of ring rolls and disposed thereon, it is characterized in that: this mould comprises core roller 3, die body 6, described die body 6 adopts with described core roller 3 and is threaded, described die body 6 is made up of hollow circular cylinder and one-side band cutting edge flange, described band cutting edge flange is set to cone flange, the large end of horn mouth of its cone flange upward, lower surface is gradient, be positioned at cylinder axis to lower end position, described rolling ring mould is arranged on the inner side of annular forging piece 4.The top of described core roller 3 arranges the shaft shoulder, and its upper end arranges screw thread.
Operation principle: during rolling, is placed in ring forging stock on core roller, utilizes the roll-force between ring rolling machine main roll and core roller that ring wall thickness is compressed, and metal tangentially direction extends, thus realizes ring diameter and constantly expand.On core roller after installation mold, groove can be extruded on the inwall of annular forging piece, thus alleviate the weight of forging.Home roll and core roller have in relative rotation, and home roll is for rotating counterclockwise, and core roller rotates clockwise, the two all dynamic device.Under the drive of home roll and core roller, annular forging piece, under the effect of frictional force, follows one piece of rotation.Cone roller is also rotate, the dynamic device of epicone roller, and be initiatively rotated counterclockwise, lower cone roller does not have power, passively under frictional force effect turns clockwise.
Certainly; above-mentioned explanation is not limitation of the utility model; the utility model is also not limited only to above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also belongs to protection domain of the present utility model.
Claims (2)
