Abstract
The utility model provides a bending press rim press forming die structure. According to the bending press rim press forming die structure, an opening portion of a female groove can not be damaged easily, cost can not be increased because a great deal of forged steel is not needed during use, and heat treatment of the structure of the female die can not be influenced. The bending press rim press forming die structure comprises the female die and a male die, wherein the female die is arranged in a female die base and the male die is arranged in a male die base. The bending press rim press forming die structure is characterized in that a hoop is arranged on the outer side of the portion, receiving the largest stress, of the outer ring of the female die.
Description
Technical field
The utility model relates to a kind of shaping moudle structure of bullodozer body parts, is specially a kind of bullodozer wheel rim pressing die structure.
Background technology
Wheel rim is the parts of wheel periphery mounting tyre.The shape of wheel rim is by pressure-shaped mould die, punch the metal stock to be exerted pressure, and forces the metal to produce plastic deformation between punch and matrix and moulding.When using existing pressure-shaped mould manufactured parts, the die oral area in use often ftractures owing to stressed larger, causes die often to change.Technology in the past is to improve cavity die structure by simple increase die thickness and size, not only can increase the use amount of forged steel, wastes in a large number resource, raises the cost, and cavity die structure heat treatment also is difficult for through hardening, and hardness can't reach requirement.
Summary of the invention
Defects for prior art, the utility model is carried and has been encircleed a kind of bullodozer wheel rim pressing die structure, it can be so that the die oral area be not fragile, and can not use in a large number forged steel to cause cost to improve, and the heat treatment that also can not affect recessed membrane structure impacts.
The technical solution of the utility model is: it comprises die and punch, and described die is installed in die socket, and described punch is loaded on convex mould base, it is characterized in that: stressed maximum outside, described die outer ring is provided with clip.
After adopting design of the present utility model, when carrying out the wheel rim die mould, because the constraint effect of clip, the die oral area is difficult for damaging because being subject to the power of horizontal direction, has prolonged service life of equipment, has reduced the use amount of forged steel, save cost, and do not affected the thermal effectiveness of cavity die structure.
Description of drawings
Fig. 1 is the partial sectional view of the utility model front view.
The specific embodiment
See Fig. 1, the utility model comprises die 2 and punch 4, and die 5 is installed in die socket 1, and punch 4 is loaded on convex mould base 5, by the hot jacket method clip 3 is set in stressed maximum outside, die 2 outer rings.
When carrying out the wheel rim die mould, die 2 is descending, because the constraint effect of 3 pairs of dies of clip, die is difficult for damaging because being subject to the active force of horizontal direction.
