Description
Technical Field
The invention relates to a ring rolling forming device for rolling and bending a single integral ring of a special-shaped connector, belonging to the technical field of forging in mechanical manufacturing.
Background
The joint is a connecting part, the section of the joint is greatly changed, the middle of the joint is a large round hole, and the flange surface is of a special-shaped structure with gradually changed thickness. In the using process, the using requirement can be met after the part is generally forged and processed, but because the part is complex in shape, thin in thickness and difficult to forge and form, the existing manufacturing method generally comprises the following steps: the method has the advantages that the product is integrally forged into a whole ring and then is mechanically processed to the final required size, and the forming device used in cooperation with the method has the advantages that in the processing process, the processing allowance of the product is large, the processing stress is large, the product streamline is discontinuous, the final size precision is difficult to guarantee, the manufacturing cost is high, and the production efficiency is low.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide the ring rolling forming device for the integral ring rolling and bending of the single piece of the special-shaped connector, which has the advantages of small machining allowance, continuous flow line, easy control of machining deformation, low manufacturing cost and high production efficiency.
In order to solve the technical problem, the ring rolling forming device for integrally ring rolling and bending the single piece of the special-shaped joint comprises a main roller die, a core roller die and a core roller die pressing block, wherein the core roller die and the core roller die pressing block are arranged in parallel and are assembled with a core roller of a ring rolling mill into a whole to form a cavity.
The die cavity is of an I-shaped structure.
The core roller of the ring rolling mill is movably arranged in a cavity formed by the core roller die and the core roller die pressing block.
The height of the cavity is the same as that of the blank before molding.
The lower plane of the main roller die and the lower plane of the core roller die are in the same horizontal plane.
The ring rolling forming device for rolling and bending the single integral ring of the special-shaped joint has the following advantages: firstly, the invention has simple structure and high production efficiency, the forge piece can be integrally bent along with the shape, the metal streamline of the forge piece is continuous, and the product quality is good. Secondly, the invention avoids the problem of large deformation and processing stress, and has low processing cost and convenient popularization and use.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in figures 1-4, the ring rolling forming device for integrally ring rolling and bending a single piece of a special-shaped joint comprises a main roller die 8, a core roller die 4 and a core roller die pressing block 5, wherein the core roller die 4 and the core roller die pressing block 5 are arranged in parallel and are assembled with a core roller 6 of a ring rolling machine into a whole to form a cavity.
The die cavity is of an I-shaped structure.
The core roller 6 of the ring rolling mill is movably arranged in a cavity formed by the core roller mould 4 and the core roller mould pressing block 5.
The height of the cavity is the same as the height of the blank 3 before forming.
The lower plane of the main roller die 8 and the lower plane of the core roller die 4 are in the same horizontal plane.
The integral forming device of the invention comprises the following processes:
heating a blank 3 (shown in figure 3) before the special-shaped joint is formed to a forging temperature and preserving heat, placing a large hole in the center of the blank 3 before the special-shaped joint is formed in a core roller 6 of a ring rolling machine after the blank is taken out of a furnace, placing a circular boss part of the blank 3 in an I-shaped cavity formed by a core roller mold 4 and a core roller mold pressing block 5, bending a flange part of the special-shaped joint by driving the core roller to move towards a main roller mold 8, stopping feeding when the outer circle of the blank 3 before the special-shaped joint is formed is contacted with the straight edge at the lower part of the main roller mold 8, moving the core roller to separate a forge piece from the main roller mold 8, and taking the forge piece out of the cavity formed by the core roller mold 4 and the core roller mold pressing block 5 to obtain the special-shaped joint product.
It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
