Abstract
The invention relates to a forging method, in particular to production of various Y-shaped blanks made of plastic forming materials. Through the forging method for manufacturing the Y-shaped blanks, the problems that the Y-shaped blanks are difficult to manufacture, boundary dimensions are inaccurate, the utilization rate of materials is low, macroscopic streamlines do not follow outlines, and energy is wasted are solved. In all links of forging operation, plate blank manufacturing, the lengths of kerfs and the positions of punched holes can be accurately controlled, and thus the outlines and dimensions of the Y-shaped blanks are easily controlled, and mass production is facilitated. The working procedures are simple, the forging heating number is small, and waste of energy for forging heating and consumption caused by self-heating of the materials are reduced. The dimensions of the blanks are easily controlled, and the maximum utilization rate of the materials can be achieved. The obtained Y-shaped blanks can maintain the original forging streamlines, and finally produced forgings can have good anti-fatigue ability.
Description
Technical field
The present invention relates to a kind of forging method, more particularly to the production of various Plastic Forming material Y shapes famine base.
Background technology
With the lifting of aviation FMT, part process technology and relevant device ability, airplane parts design
Also constantly towards maximizing, integration direction develops.In order to the performance of strength member it is good and easy to process, foundation
High accuracy is typically required when part is related to forging, it is desirable to adopt forging part.Because the shape of aircraft structure forging part is answered
Miscellaneous, the production difficulty of forging blank is very big, and particularly with branch shape characteristic shape, (blank is overall or local is in Y
Shape shape) forging famine base.At present, adopting the waste base of this Y types branch more first bar is swaged into into square billet,
There is the qualified position sub-material of certain distance on length direction away from termination, be finally curved and make.This method forging fire
It is secondary many, it is molded inaccurate.Improved by the adjustment of Hongyuan company of Air China, invented a kind of simple, accurate and can realize
The Y shape famine base manufacture method of high stock utilization.
The content of the invention
Technical problem solved by the invention is：By the forging method that Y shape famine base is manufactured in the present invention, Y is solved
Shape famine base base is difficult, appearance and size is inaccurate, and the utilization rate of material is low, and low power streamline is not along profile, energy dissipation etc.
Problem.
The technical scheme that the present invention takes is：The production that Y shape famine base is realized by the way of seam is split using slot-punching.
Step is as follows：
(1) blank prepares：By bar by changing forging, rectangle famine base is made；
(2) slot：The thin of corresponding length is cut out on rectangle famine base according to the length and width of forging Y shape bifurcated
Seam, forms two branch arms being close together；
(3) seam is split in punching：The waste base for there are two branch arms being close together is put on flat anvil, is selected in the root of slot
The drift punching of suitable diameter is selected, two branch arms are certain because the plasticity of material can open automatically at slot during punching
Angle；
(4) blank shaping：The angle that two support arm broadenings after according to the actual requirements is opened blank need to forging,
Then two arms are curved or are pulled out and comply with waste base requirement, complete forging.
The invention has the beneficial effects as follows：(1) links of forging operation：Making sheet base, slot length, punching
Position can precise control so that the profile of Y-shaped famine base, size are easily controlled, it is easy to produce in enormous quantities.(2)
Operation is simple, and forging times are few, the consumption that the waste and material conducting self-heating for reducing the Forge Heating energy is produced.
(3) waste base size is easily controlled, and can realize the peak use rate of material.(4) the Y-shaped blank for obtaining can
Retain original forging flow lines, the forging of final production there can be preferable anti-fatigue ability.
Specific embodiment
With reference to example, the present invention is described in further detail.
The structural member of certain large-scale military aircraft be a Y shape branch, two branch cross-sectional areas be 203mm × 80mm,
The identical 700mm of branch length, branch angle is 60 °, and the specification that feeds intake is：According in the present invention
Technical scheme forged：
(1) blank prepares：
WillBar by changing forging, make the waste base of rectangle of 1400mm × 440mm × 100.
(2) slot：
In the longitudinal direction the 440mm of width is divided into into two about with Water Cutting, wire cutting or sawing machine
215mm wide parallel branch arm, Cutting Length is 700mm, it is ensured that the width of thin seam is less than 10mm, cuts gradient
Less than 1 °, two branch arms being close together are formed.
(3) seam is split in punching：
There to be above-mentioned waste base to be put on flat anvil, select a diameter of in the root of slotDrift punching.Punching
When two branch arms about 30 ° can be automatically opened at slot due to the plasticity of material.
(4) blank shaping：30 ° of branch is separated to 60 °, base is completed.
According to heretofore described method, the base fire time in this example is fiery for 3, and fewer than original blank-making method 6
Fire, stock utilization is improved to 85%.
Claims (1)
1. the forging method of a kind of plastic material Y shape famine base, it is characterised in that comprise the steps：
(1) blank prepares：By bar by changing forging, rectangle famine base is made；
(2) slot：The thin of corresponding length is cut out on rectangle famine base according to the length and width of forging Y shape bifurcated
Seam, forms two branch arms being close together；
(3) seam is split in punching：The waste base for there are two branch arms being close together is put on flat anvil, is selected in the root of slot
The drift punching of suitable diameter is selected, two branch arms are certain because the plasticity of material can open automatically at slot during punching
Angle；
(4) blank shaping：The angle that two support arm broadenings after according to the actual requirements is opened blank need to forging,
Then two arms are curved or are pulled out and comply with waste base requirement, complete forging.
