Description

The mould that is used for warm forging processing flange part

Technical field

The utility model relates to the forging die field for forging and pressing, is specially a kind of mould for warm forging processing flange part.

Background technology

Flange is the common part on equipment, is comprised of neck flange and flange chassis two parts.Present pressure processing production technology is: heating → forging forming → edge-cutting and hole-punching, after forging forming, can form fibr tissue in part, and also claim streamline.For the mechanical performance of part, improve in the direction plasticity that is parallel to fiber and toughness, vertical direction reduces; During edge-cutting and hole-punching adopt turning processing, turning adds the man-hour fibr tissue and is cut off, and not only increases raw materials consumption, and has reduced the mechanical performance of part, has shortened service life more.

The utility model content

In order to overcome the defective of prior art, provide a kind of simple in structure, easy to process, mechanical performance is high, the mould of long service life, the utility model discloses a kind of mould for warm forging processing flange part.

The utility model reaches goal of the invention by following technical solution:

A kind of mould for warm forging processing flange part comprises anvil block, it is characterized in that: also comprise lower-left forging die, bottom right forging die, upper forging die, lower anvil pad, upper left anvil pad and upper right anvil pad,

Lower anvil pad is located between lower-left forging die and bottom right forging die, and upper forging die is located between upper left anvil pad and upper right anvil pad; Upper left anvil pad be located at the lower-left forging die directly over, upper right anvil pad be located at the bottom right forging die directly over, upper forging die be located at lower anvil pad directly over; The middle part of lower anvil pad top end face is provided with lower convex platform, and the both sides of lower convex platform form low groove after fitting in respectively the sidewall of the sidewall of lower-left forging die and bottom right forging die; The middle part of upper forging die bottom face is provided with convex platform, and the both sides of convex platform form upper groove after fitting in respectively the sidewall of the sidewall of upper left anvil pad and upper right anvil pad.

Described mould for warm forging processing flange part is characterized in that: this central axes of lower anvil pad, lower convex platform, upper forging die and convex platform; The diameter of lower convex platform is 50%～70% of lower anvil pad diameter, and the diameter of convex platform is 40%～60% of upper forging die diameter.

When the utility model uses, cavity between lower-left forging die, bottom right forging die, lower anvil pad, upper left anvil pad, upper right anvil pad and upper forging die is as impression, blank after heating is placed on lower-left forging die, bottom right forging die and lower anvil pad, start die forging machine, upper left anvil pad, upper right anvil pad and upper forging die are pressed down, blank is pressed into Flange-shaped Parts, completes again subsequently the processing of flange through punching.

The utility model has overcome the drawback that causes mechanical performance to reduce because of machining cut staple tissue after existing flange forming, has improved the product working strength.

The beneficial effects of the utility model are: simple in structure, easy to process, mechanical performance is high, long service life, low cost of manufacture.
