Abstract

The utility model provides a die forging structure of a titanium alloy rocker arm, which solves the problem that two high tendons of a forge piece are likely to collapse at corners during die forging with an existing die forging structure, and has the advantages that the die forging technical flow is effectively shortened and the production efficiency is improved. The structure comprises a forge piece body, wherein the upper and lower molded surfaces of the forge piece body are symmetrical and high tendons are arranged on the longitudinal sides of the upper and lower molded surfaces. The structure is characterized in that the parting surface of the forge piece body is located below the symmetrical central line of the upper and lower faces of the forge piece body.

Description

A kind of titanium alloy rocking arm die-forged part structure

Technical field

The utility model relates to the structure design field of die-forged part, especially relates to the structure design field of titanium alloy die forging part, is specially a kind of titanium alloy rocking arm die-forged part structure.

Background technology

A kind of titanium alloy rocker component for aircraft system, its appearance profile is of a size of 396mm × 206mm × 140mm(length × wide × height), structure is shown in Fig. 1, the principal feature of this member is that the height to width ratio of two sides side plate 1 is 8:1, belong to complex structural member, and its material is TC4 titanium alloy, belongs to difficult-to-deformation material.The common forging structure of this member is shown in Fig. 2 and Fig. 3, on the Joint face of a pattern 5 and forging of its forging 4, symmetrical center line 11 below overlaps, this forging carries out die forging on 180MN flypress, forming speed is 50mm/sec, in die forging process, often there will be following problem: when (1) carries out titanium alloy product production on flypress, blank and counterdie are long contact time, temperature drop is very fast, therefore counterdie metal flow difficulty in production process, counterdie die cavity is difficult for filling, thereby cause the high muscle 2 of the structural twice of forging, 3 fill difficulty at die forging process, easily produce the angle of collapsing, (2) in contour forging technique, for solving the angle problem of collapsing of the high muscle of above-mentioned twice, Forging Technology adopts the be shaped mode of twice die forging of preforming and finish-forging, and its production efficiency is low.In Fig. 3,6 patrixes that are forging die, 7 counterdies that are forging die, H0 is the height of the

high muscle

2,3 of forging, and H is forging thickness, and h is the height between forging body Joint face of a pattern and forging lower plane A.

Summary of the invention

For the problems referred to above, the utility model provides a kind of titanium alloy rocking arm die-forged part structure, it can solve the high muscle of twice that adopts the die forging of existing forging structure to add forging in man-hour and easily produce the problem at angle of collapsing, thereby effectively shortens contour forging technique flow process, enhances productivity.

Its technical scheme is such, it comprises forging body, the upper and lower profile symmetry of described forging body, the upper and lower profile of described forging longitudinally both sides is respectively arranged with high muscle, it is characterized in that: the Joint face of a pattern of described forging body is positioned at the below of the symmetrical center line of described forging body above and below.

It is further characterized in that: the height h of described forging body Joint face of a pattern and described forging lower plane is 0.2 times ~ 0.4 times of described forging thickness H.

The utility model titanium alloy rocking arm die-forged part structure, the more existing forging structure of its forging body Joint face of a pattern Joint face of a pattern moves down, be conducive to the high muscle of counterdie position cavity filling, and the height h that controls forging body Joint face of a pattern and described forging lower plane is 0.2 times ~ 0.4 times of described forging thickness H, thereby can reduce the temperature drop that reduces forging contact time of forging and forging die counterdie, thereby reduce the impact of temperature drop on forging tissue in die forging process, further guarantee the cavity filling of the high muscle of forging counterdie position, forging can put in place at a fire time internal shaping, thereby it is inferior to have reduced the fire that is shaped, improve capacity utilization rate, effectively improve production efficiency.
