Abstract

The invention provides a titanium alloy rocker die forging structure. According to the titanium alloy rocker die forging structure, the problem that two high ribs of a forging cause corner collapse easily when a conventional forging structure is used for forging and machining can be solved, so that the forging process flow is shortened effectively and the production efficiency is improved. The titanium alloy rocker die forging structure comprises a forging body, wherein an upper molded surface and a lower molded surface of the forging body are symmetrical; the high ribs are respectively arranged along the two longitudinal sides of the upper molded surface and the lower molded surface of the forging. The titanium alloy rocker die forging structure is characterized in that a die parting surface of the forging body is positioned below the symmetrical center line of the upper molded surface and the lower molded surface of the forging body.

Description

Titanium alloy rocking arm die-forged part structure

Technical field

The present invention relates to the structure design field of die-forged part, especially relate to the structure design field of titanium alloy die forging part, be specially 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 invention provides 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 of described forging body is symmetrical, 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.

Titanium alloy rocking arm die-forged part structure of the present invention, 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, improved capacity utilization rate, effectively improved production efficiency.
