Problems solved by technology

There are many trimming methods in the field of forging technology, but there are relatively few trimming methods for titanium alloy blades. The main reason is that titanium alloy blades are easily deformed after trimming. At present, the trimming methods of titanium alloy blades after forging are: one is forging After direct hot cutting, this method is suitable for large blades, but it is prone to deformation. After deformation, auxiliary processes such as correction and stress relief are required, and the processing cost is high; the second is to use band saw, water jet or wire cutting after forging. , the production cost of this method is relatively high, and the efficiency is low, so it is not suitable for mass production
Precision forged blades mean that the blade body is forged to the finished size, so it has high requirements for forging technology, especially the requirement that the edge cannot be deformed after trimming. Currently, there is no effective means to completely control the deformation, so most of the precision forged blades rely on edge trimming. Waterjet, wire cutting and other methods, low efficiency and high production cost

Abstract

The invention provides a cold cutting die for a titanium alloy precision-forged blade, which can effectively control the deformation for the side cut of the titanium alloy blade, improve the production efficiency and lower the production cost. The cold cutting die comprises an upper die plate and a lower die plate, as well as a punch and a lower die, wherein the upper die plate and the lower die plate are connected by a guide pillar and a ball guide sleeve in a matching manner, the punch is arranged on the lower die plate by a punch base plate, the cold cutting die is characterized in that the lower die comprises a female die and a support die, the female die is fixedly arranged on the lower die plate by a screw, the female die is internally provided with a vertical through slot and a horizontal through slot which are perpendicularly communicated, the support die is arranged in the vertical through slot, the lower end of the support die is supported by a rubber mat, the rubber mat is arranged on the lower die plate and positioned in the horizontal through slot, and the support die is 3-5mm higher than the female die under non-working state.

Description

technical field [0001] The invention relates to the technical field of forging titanium alloy blades, in particular to a cold cutting die for precision forging titanium alloy blades. Background technique [0002] During die forging, the excess material overflows from the junction of the upper die and the lower die to form flash, and removing flash is an indispensable process in the die forging process. There are many trimming methods in the field of forging technology, but there are relatively few trimming methods for titanium alloy blades. The main reason is that titanium alloy blades are easily deformed after trimming. At present, the trimming methods of titanium alloy blades after forging are: one is forging After direct hot cutting, this method is suitable for large blades, but it is prone to deformation. After deformation, auxiliary processes such as correction and stress relief are required, and the processing cost is high; the second is to use band saw, water jet or w...
