Abstract
The present invention relates to the forging method that a kind of forging part improves blank shaping, comprise the following steps that：Step 1：A prefabricated blank；Step 2：On two arms of blank, cut from the side of two arms and the excessive of bar portion, the depth of cutting is identical with the thickness of blank, the direction of cutting is opposite with the bearing of trend of bar portion, the volume cut open is equal with the volume of one arm of blank, Cutting Length is no more than the 1/4 1/3 of the rectangular body length of two-arm, also identical is cut using above-mentioned at the excessive place of opposite side and the bar portion of two arms；Step 3：Blank heating after cutting, the cut place in the side of two arms is split with wedge and cut place is open, and A/F is the 1/6 1/5 of two arm width；Step 4：Blank is forged with special shaping fetal membrane, cavity plate depanning angle is 1.5 3 degree.The present invention can reduce production cost, avoid forging base from being defect, reduction production difficulty, the fiery inferior economic problems of reduction production.
Description
Technical field
The present invention relates to the technical field of forging of forging.
Background technology
Usual cross-shaped forging piece be by bar heat after by fetal membrane Upsetting, slightly pulling is forged into die forging base afterwards, forged by shaping
Cause required cross-shaped forging piece；But the above method has that Making mold is costly, forging times are more, operation difficulty is big and office
Portion adds the problems such as hindering so that forging production cycle, costly and operation difficulty are big, cause the production process of made forging
The economic problems that many, defect is serious, percent defective is too high.
The content of the invention
The technical problems to be solved by the invention are：Production cost is reduced, avoids forging base from being defect, reduce production hardly possible
The inferior economic problems of degree, reduction production fire.
The technical scheme is that：In order to avoid the Making mold in cross-shaped forging piece forging process is costly, operation
The problems such as fiery more, operation difficulty is big and local plus hinders, spy proposes a kind of forging method of cross forging part：
Step 1：A prefabricated blank, blank is divided into head, two arms and bar portion, and each portion is that cross section is unequal
But the equal cuboid of thickness, since the bar portion termination of blank, is followed successively by the use of head, two-arm and the bar portion of cross-shaped forging piece
Expect volume；Its width and length are identical with the head of cross-shaped forging piece, two-arm and bar portion volume；
Step 2：On the arm of blank two, from the side of two arms and the excessive of bar portion cut, the depth of cutting
Identical with the thickness of blank, the direction of cutting and the bearing of trend of bar portion are on the contrary, the volume cut open and the body of one arm of blank
Product is equal, and Cutting Length is no more than the 1/4-1/3 of the rectangular body length of two-arm, opposite side and the excessive place of bar portion in two arms
Identical cut using above-mentioned；
Step 3：Blank heating after cutting, the cut place in the side of two arms is split with wedge and cut place is opened
Mouthful, A/F is 30mm-55mm, the blank being open is forged to required size again, another arm uses above-mentioned same procedure
Opening and forging；
Step 4：Blank is forged with special shaping fetal membrane, cavity plate depanning angle is 1.5 degree of -3 degree.
The beneficial effects of the invention are as follows：By prefabricated multi-section cuboid blank, the method split using continuous body,
Eventually passing improves shaping fetal membrane angle to forge the cross-shaped forging piece needed for completing；Above-mentioned forging method avoids cross
Making mold during forging process for fuel is costly, operation fire time is more, operation difficulty is big and local plus the problems such as hinder, this method
Production cost is reduced, avoids forging base from being defect, reduce production difficulty, reducing the inferior economic problems of production fire.
Embodiment
The present invention is described in further detail below by specific embodiment
Some part of the aircraft engine nacelle of French Aerospace PLC, BAe's design employs Ti-6Al-4V titanium alloy materials,
The processing request of the part provides a criss-cross forging；Accordingly using the forging method of cross forging part of the invention：
Step 1：A prefabricated blank, 965 are heated to by diameter 180mm, long 430mm Ti-6Al-4V titanium alloy rod bars
After DEG C ± 10 DEG C, blank is forged to head length for 85mm successively；Width is that 214mm, two-arm minister's degree are 120mm；Width is
115mm；Bar portion length is 235mm；Width is 40mm cuboid, and the equal thickness of the blank is 90mm；
Step 2：Cut in blank using Water Cutting, on the arm of blank two, from the side of two arms and bar portion
Excessive place starts cutting, and the depth of cutting is identical with the thickness of blank, is 90mm, the direction of cutting and the bearing of trend phase of bar portion
Instead, the volume cut open is equal with the volume of one arm of blank, and Cutting Length is 50mm；In the opposite side and bar portion of two arms
Excessively place also identical is cut using above-mentioned；Cutting Length is 50mm；
Step 3：By blank heating to after 965 DEG C ± 10 DEG C, the cut place in the side of two arms is split with wedge to cutting
Place is open, and A/F is 45mm, and it is 230mm that the blank being open is forged to length again；Width is i.e. forging after 40mm
The arm of part one is molded, and another arm uses above-mentioned same procedure opening and forging；
Step 4：Blank heating to 965 DEG C of ± 10 DEG C of shaping depanning angles is used into cavity plate depanning angle for 3 shaping fetal membranes
In be depressed into the angle of forging drawing requirement.
The Ti-6Al-4V titanium alloy cross-shaped forging pieces prepared using the forging method of the present invention, meet XX companies to Ti-
The streamline of 6Al-4V titanium alloy cross-shaped forging pieces requires and has reached it to the above-mentioned mould avoided in cross-shaped forging piece forging process
The problems such as tool manufacturing expense is high, the secondary more, operation difficulty of operation fire is big and local plus hinders.
