Abstract
The utility model discloses a roller of a ring rolling machine for rolling an internal step section ring piece, and belongs to ring piece rolling molds. The roller comprises a driving roller, a core roller and conical rollers, wherein a boss is arranged on the working surface of the core roller; radial rolling adopts an open hole pattern; and a pair of conical rollers are added to control the axial height of a ring forged piece. By using the roller of the ring rolling machine for the rolling the internal step section ring piece provided by the utility model, radial and axial rolling can be performed, the quality of an end surface is improved, a ring forged piece which is more accordant with a final product can be obtained, raw material consumption and processing cost are reduced, and the utilization rate of materials is improved, so that the roller has very good popularization and application value.
Description
Technical field
The utility model relates to a kind of ring rolling mould, especially a kind of rolling Ring Rolling Machine roll of inner step profile section ring parts that is used for.
Background technology
Inner step profile section ring die forging spare is because its special shape and excellent mechanical property have application widely in nuclear power, wind energy, petrochemical industry equal energy source field and weight equipment.At present, inner step profile section ring parts adopts radial rolling to add machine cut processing associating completion usually.Roll in the ring-rolling process at inner step profile section ring parts; Ring rolls driven roller and core roller are straight working face; The ring that processes is the square-section, promptly processes the ring of square-section earlier through radial rolling, through machine cut the square-section ring is processed into trapezoidal rank section ring parts again.Utilize the subject matter of this roll production trapezoid cross section ring to be: (1) allowance is big, and wastage of material is serious, and stock utilization is low; (2) production efficiency is low, and labour intensity is big; (3) ring rolling ring-rolling process moderate heat is inferior many, and forging needs repeated heating, and energy consumption is high; (4) rolling ring-rolling precision is low, and geomery is difficult to guarantee that percent defective is high; (5) follow-up machining allowance is big, and length consuming time is big to lathe, tool wear; (6) production cost is high.
Summary of the invention
The purpose of the utility model is for overcoming the deficiency of above-mentioned prior art, a kind of rolling Ring Rolling Machine roll of inner step profile section ring parts that can be used for being provided.This roll can carry out axially bidirectional rolling of footpath; Improved the end face quality; Can obtain the ring rolling spare more approaching, reduce raw materials consumption and processing charges, reduce labour intensity with final finished; Improve stock utilization, can well solve the problem that the inner step profile section ring parts tradition occurs when rolling.
For realizing above-mentioned purpose, the utility model adopts following technical proposals:
A kind of rolling Ring Rolling Machine roll of inner step profile section ring parts that is used for comprises driven roller, core roller and awl roller, and described core roller working face is provided with boss, and radial rolling adopts open pass, has added a pair of awl roller control loop forging axial height.
Described core roller working face convex platform height equals the rolling big bore portion height H of inner step profile section ring parts of wanting
b, land length equals the difference B of thick end face width of inner step profile section ring parts and thin end face width
b-B
s
The Ring Rolling Machine roll of the utility model invention is used for the rolling rolling ring-rolling of inner step profile section ring parts, compared with prior art; Has following outstanding advantage: added a pair of awl roller control loop forging axial height; Reduce raw materials consumption and processing charges, improved production efficiency, saved the production time; Easy to use, simple in structure.The utility model is significant to the rolling ring-rolling of inner step profile section ring parts, has the excellent popularization using value.
Description of drawings
Fig. 1 is a roll sketch map radially;
Fig. 2 is the axial roll sketch map.
The specific embodiment
With reference to Figure of description 1 and accompanying drawing 2, to detailed explanation below the utility model work.
Shown in Fig. 1-2; A kind of rolling Ring Rolling Machine roll of inner step profile section ring parts that is used for, its structure comprise driven roller 1, core roller 3 and awl roller 4, and described core roller 3 working faces are provided with boss; Radial rolling adopts open pass, has added a pair of awl roller 4 control loop forging axial heights.
Described core roller working face convex platform height equals the rolling big bore portion height H of inner step profile section ring parts of wanting
b, land length equals the difference B of thick end face width of inner step profile section ring parts and thin end face width
b-B
s
The concrete course of work of roll in the utility model: under rolling motion of the rotation of driven roller 1 and straight-line feed motion effect; Ring blank 2 nip continuously driven roller 1 and the rolling groove that core roller 3 constitutes, the moulding distortion of continuous and local that produce that wall thickness reduces, enlarged-diameter, section of outline is shaped.Get into axial pass down, the moulding distortion that the generation axial height reduces in a pair of awl roller 4 rotations and straight-line feed motion effect again through the blank behind the pass radially.Before the rolling beginning, guarantee ring blank accurate location in pass, and guarantee good lubricated and cooling.
Claims (2)
1. one kind is used for the rolling Ring Rolling Machine roll of inner step profile section ring parts; Structure comprises driven roller, core roller and awl roller; It is characterized in that: described core roller working face is provided with boss, and radial rolling adopts open pass, has added a pair of awl roller control loop forging axial height.
2. the rolling Ring Rolling Machine roll of inner step profile section ring parts that is used for according to claim 1 is characterized in that: described core roller working face convex platform height equals the rolling big bore portion height H of inner step profile section ring parts of wanting
b, land length equals the difference B of thick end face width of inner step profile section ring parts and thin end face width
