Abstract
The utility model provides a core roller for forging bow-shaped seat. The core roller comprises a core roller main body, a reducing rod and transition arcs, wherein rod-shaped objects are fixedly connected to two ends of the core roller main body respectively, the transition arcs are arranged between the core roller main body and the rod-shaped objects, and one of the rod-shaped objects is the reducing rod. The technical scheme is that a transition arc is additionally arranged in the middle of a core roller main body, the whole core roller main body is designed into a step-shaped structure, and the working front end of the core roller main body is designed into an inclined structure; based on the structure, the problems that the blank processing amount of a forged piece processed by the traditional core roller is uneven, the internal processing amount of the upper end and the lower end of the forged piece is small, and the internal processing amount of the middle part is large are effectively solved, so that the problems that the blank quality of the forged piece is large, the waste of materials and processing working hours is serious, and the strength of the forged piece is reduced due to the large amount of cutting are solved. The utility model discloses a carry out institutional advancement to the core roller and promoted the forging quality, help improving the market competition and the market share of product.
Description
Technical Field
The utility model belongs to the technical field of the machine-building, concretely relates to a core roller for forging bow-shaped seat.
Background
In tire manufacturing processes, tire molds are a very widely used piece of equipment. The arch seat is an important component of a tire mold, and generally adopts a configuration with a larger inner diameter at the middle part and smaller inner diameters at the upper end and the lower end. In the prior art, the outer diameter of a core roller for machining the arch-shaped seat is in a straight cylinder shape, so that the machining amount of a forging stock of the arch-shaped seat is uneven, the machining amount of the inner diameter of the upper end and the lower end of the forging stock is smaller, and the machining amount of the inner diameter of the middle part of the forging stock is overlarge. Therefore, on one hand, the forging has larger mass, and the waste of materials is caused; on the other hand, a large amount of metal needs to be cut off in the subsequent processing link, so that the subsequent processing time is increased; more importantly, because the shape difference between the forging stock and the final product is large, the original structure in the forging stock is damaged by a large amount of cutting on the forging stock in subsequent processing, and the strength of the forging stock is obviously reduced.
Disclosure of Invention
The utility model discloses aim at to prior art's technical defect, provide a core roller for forging bow-shaped seat to solve prior art, be used for forging bow-shaped seat conventional core roller can lead to the less, the too big technical problem of middle part internal diameter work load of forging stock upper and lower end internal diameter work load.
The utility model discloses the technical problem that further solve is, the forging stock quality that conventional core roller processed is great, therefore extravagant material and processing man-hour.
The utility model discloses the technical problem that further solve is, the forging stock that conventional core roller processed need carry out a large amount of excision, therefore influences forging intensity.
In order to realize the technical purpose, the utility model adopts the following technical scheme:
the core roller for forging the arch-shaped seat comprises a core roller main body, reducing rods and transition arcs, wherein rod-shaped objects are fixedly connected to two ends of the core roller main body respectively, the transition arcs are arranged between the core roller main body and the rod-shaped objects, and one of the rod-shaped objects is the reducing rod.
Preferably, the core roller main body has a stepped shape.
Preferably, the reducing rod is fixedly connected to the working front end of the core roller body.
Preferably, an equal diameter rod is fixedly connected to a rear end of the core roll body, and an axis of the equal diameter rod and an axis of the reducing rod are overlapped with each other.
In the technical scheme, the transition circular arc is arranged in the middle of the core roller main body, and the core roller main body is designed into a step-shaped structure. The working front end of the core roller main body is designed into an inclined structure.
The utility model provides a core roller for forging bow-shaped seat. The technical scheme is that a transition arc is additionally arranged in the middle of a core roller main body, the whole core roller main body is designed into a step-shaped structure, and the working front end of the core roller main body is designed into an inclined structure; based on the structure, the problems that the blank processing amount of a forged piece processed by the traditional core roller is uneven, the internal processing amount of the upper end and the lower end of the forged piece is small, and the internal processing amount of the middle part is large are effectively solved, so that the problems that the blank quality of the forged piece is large, the waste of materials and processing working hours is serious, and the strength of the forged piece is reduced due to the large amount of cutting are solved. The utility model discloses a carry out the improvement of structural layer to the core roller and promoted the forging quality, help improving the market competition and the market share of product. The core roller has the advantages of simple structure, strong practicability and strong popularization and application values.
