Abstract

The utility model provides a titanium alloy large-size rib die forging structure. The titanium alloy large-size rib die forging structure effectively resolves the problem of difficult filling of an existing structure, improves the utilization rate at the same time, effectively lowers deformation resistance and reduces forming heating number. The titanium alloy large-size rib die forging structure comprises a titanium alloy large-size rib die forging body, wherein high ribs in the length direction are symmetrically arranged at two longitudinal sides of the upper plane of the forging body. The titanium alloy large-size rib die forging structure is characterized in that the upper plane located between the high ribs of two sides of the forging body is arranged below a forging die-splitting surface.

Description

A kind of titanium alloy large-sized rib forging part structure

Technical field

The utility model relates to the structural design field of forging part, especially relates to the structural design field of titanium alloy large-sized forging part, is specially a kind of titanium alloy large-sized rib forging part structure.

Background technology

A kind of large titanium alloy member, its appearance profile is of a size of 1100mm * 220mm * 210mm(length * wide * height), structure is seen Fig. 1, the main feature of this member is that the depth-width ratio of two sides side plate is 44:1, belong to complex structural member, and material belongs to difficult-to-deformation material.Traditional forging 6 structures of this member are seen Fig. 2 and Fig. 3, the A face 5(of the forging plane that is the forging body between the high muscle in both sides) above the forging die joint, this forging carries out die forging at the 355MN flypress, forming speed 500mm/sec, blank adopts the direct die-forging forming of φ 250mm bar, 7 is the patrix of forge die among Fig. 3,8 is the counterdie of forge die, following problem appears in regular meeting in die forging process: the high muscle die forging process of the structural twice of (1) forging is filled difficulty, is easy to generate the angle of collapsing; (2) stock utilization is low, forge weight 170Kg, and cutting stock weight 272Kg, stock utilization only is 62.5%; The more die-forging forming power that causes of overlap is big when (3) forging, and surpasses the maximum hitting power of equipment; (4) production efficiency is low, and in order to reduce die-forging forming power, every fire all needs to cut overlap, generally needs 4 fiery apotypes to be swaged into shape.Shown in Fig. 4 ~ 5, among Fig. 4, Fig. 5,10 is forge piece blank reheating, for selecting φ 238mm and φ 250mm bar die-forging forming schematic diagram for use, the as can be seen from the figure more easy filling of the more big high muscle of bar diameter, but the problem of bringing along with the increase of bar diameter is problems such as stock utilization decline, hitting power increase, forging times increase.

Summary of the invention

At the problems referred to above, the utility model provides a kind of structure of titanium alloy large-sized rib forging part, it can effectively solve the filling difficult problem that existing structure exists, and has improved stock utilization simultaneously, effectively reduces resistance of deformation and has reduced the fiery inferior problem that is shaped.

Its technical scheme is such, it comprises titanium alloy large-sized rib forging part body, the vertical bilateral symmetry in plane is provided with high muscle along its length on the described forging body, it is characterized in that: described forging body plane between the high muscle in both sides be arranged at the forging die joint below.

It is further characterized in that: described forging body discrepancy in elevation distance H between plane and the described forging die joint between the high muscle in both sides is 2 times～3 times of the height h of bridge portion.

Compare with existing forging structure, the beneficial effects of the utility model are: move on the forging die joint and forging body plane between the high muscle in both sides is lower than die joint, make that metal is easier of high muscle filling when die forging, blank diameter is corresponding like this reduces, thereby raising stock utilization, reduce the single-piece cutting stock weight greatly, and blank diameter reduce effectively to control the overlap that produces in the die forging process, reduce the shaping drag, so the hitting power of required shaping is corresponding minimizing also, forging can put in place by 1 fire time internal shaping, reduce the fire that is shaped, improved usage ratio of equipment, also improved production efficiency.
