Abstract
The utility model belongs to the technical field of machine manufacturing and provides a special-shaped main roller for rolling a welding neck flange. An annular inclined face and an annular concave face are machined on the middle lower portion of a working part of a main roller body, and transitional circular arcs are arranged on the annular inclined face and the annular concave face. All the working parts of the main roller body adopts the circular arcs for transition, and therefore metal flow resistance and pressure when the main roller body rolls a forge piece are effectively reduced. A main roller working face adopts the structure of a straight face, the inclined face, the circular arc transition and the concave face, the fact that metal is filled between the annular inclined face and the annular concave face on the main roller body and between the main roller body and a core roller is benefited, the metal is fully filled between the annular inclined face and the annular concave face on the main roller body and between the main roller body and the core roller when the metal is in plastic deformation, formation of the forge piece is convenient, and therefore an ideal structural shape is rolled, and an expected annular piece shape and annular piece expected dimension are achieved. The welding neck flange main roller is simple in structure and strong in practicability, reduces the weight of the forge piece, improves the strength of the forge piece, reduces machining difficulty, reduces machining time and has strong popularization and application value.
Description
Technical field
The utility model belongs to machinery manufacturing technology field, relates in particular to a kind of home roll of hubbed flange.
Background technology
As the hubbed flange forging, principal character is the hub that an abnormal shape is arranged at the workpiece external diameter, if this hub is shut out, just must process an annular slope, a loop concave at the home roll cylindrical, make metal when plastic deformation, it is full of, thereby reach the shape and size of expection workpiece.
The cylindrical that existing home roll adopts is for facing directly, and the workpiece of rolling over system is straight-flanked ring, and namely waste material has increased the metal working difficulty of processing again, has prolonged process time, has strengthened processing cost.
The utility model content
The purpose of this utility model is to provide a kind of home roll of rolling over hubbed flange processed, be intended to solve external diameter that home roll adopts that prior art provides for facing directly, the straight-flanked ring of rolling over out, namely waste material has increased the metal working difficulty of processing again, prolong process time, strengthened processing cost.
The utility model is achieved in that a kind of rolling hubbed flange home roll processed, and this hubbed flange home roll comprises: home roll main body, annular slope, transition arc, loop concave;
The cylindrical middle and lower part of home roll main body is provided with annular slope, loop concave; Connection, the transition portion of home roll main body, annular slope, loop concave are provided with transition arc.
Further, the cylindrical top of described home roll main body is for facing directly.
The hubbed flange home roll that the utility model provides is made of home roll main body, annular slope, transition arc, loop concave; The cylindrical middle and lower part of home roll main body is provided with annular slope, loop concave, and annular slope, loop concave are provided with transition arc; Arc transition is taked in each working position of home roll main body, the pressure when having reduced metal flow resistance and home roll main body effectively and rolling over forging processed; The home roll main body adopts annular slope, loop concave structure, be convenient to the moulding of forging, the folded line of having avoided producing because of the right angle in the operation of rolling of forging is with loose, thereby roll out desirable planform, make metal when plastic deformation, annular slope, loop concave are full of simultaneously, reach the ring shape and size of expection; This hubbed flange home roll is simple in structure, practical, has stronger popularization and using value.
Description of drawings
Fig. 1 is the structural representation of the kettle flange home roll that provides of the utility model embodiment.
Among the figure: 1, home roll main body; 2, annular slope 3, transition arc; 4, loop concave
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Fig. 1 shows the structure of the hubbed flange home roll that the utility model embodiment provides.For convenience of explanation, only show the part relevant with the utility model embodiment.
This hubbed flange home roll comprises: home roll main body 1, annular slope 2, transition arc 3, loop concave 4;
The cylindrical middle and lower part of home roll main body 1 is provided with annular slope 2, and loop concave 4,2,4 is provided with transition arc 3.
In the utility model embodiment, arc transition is taked in each working position of home roll main body 1.
In the utility model embodiment, home roll main body 1 adopts annular slope, loop concave structure.
Below in conjunction with drawings and the specific embodiments application principle of the present utility model is further described.
As shown in Figure 1, this hubbed flange home roll comprises: home roll main body 1, annular slope 2, transition arc 3, loop concave 4; The cylindrical middle and lower part of home roll main body 1 processes an annular slope 2, loop concave 4, and home roll main body 1, annular slope 2, the connection of loop concave 4, transition portion are processed into transition arc 3; Cooperate by core roller and this hubbed flange home roll, roll out the planform of wanting, after using this hubbed flange home roll, roll over the initial stage processed, the upper end of the working portion of home roll main body 1 at first contacts with workpiece, the middle and lower part is unsettled, forging radially extends, and (this home roll main body 1 adopts the annular slope structure, is beneficial to metal to the filling of home roll loop concave portion, moulding with workpiece) fills annular slope 3 and loop concave 4, make the forging moulding.
Every of the workpiece weight of this hubbed flange home roll forging can reduce more than 1/3, and economical with materials has improved profit margin and the competitive advantage of product, and forging is stressed even relatively, has guaranteed product quality effectively.
The hubbed flange home roll that the utility model embodiment provides, arc transition is taked in each working position of home roll main body 1, the pressure when having reduced metal flow resistance and home roll main body 1 effectively and rolling over forging processed; Be beneficial in the metal filled annular slope 2, loop concave 4 on home roll main body 1, be convenient to the moulding of forging, the forging of having avoided producing because of the right angle in the operation of rolling is folded line, thereby roll out the planform of wanting, make metal when plastic deformation, loop concave 4 is full of simultaneously, reach the ring shape and size of expection; This hubbed flange home roll is simple in structure, practical, alleviates the weight of forging, improves the intensity of forging, reduces machining time and difficulty, has stronger popularization and using value.
Below only be preferred embodiment of the present utility model, not in order to limiting the utility model, all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
