Abstract
The invention relates to a processing method of Z-shaped titanium-alloy sheet metal parts with high curvature and short bending edges. The processing method comprises the following steps of: establishing a mathematical model of the Z-shaped titanium-alloy sheet metal part; remaining a technological allowance of one edge of the relatively short bending edge in the mathematical model, setting end faces as symmetrical faces, and performing image processing on the Z-shaped titanium-alloy sheet metal part, thus obtaining a technological mathematical model; designing and manufacturing a moulding bed according to the technological mathematical model, feeding sheet metal, and then thermally forming the sheet metal; and separating the processed sheet metal based on the symmetric faces, and then removing the allowance, thus obtaining the left and right qualified parts. According to the method, the two symmetrical parts are synchronously processed, therefore, the internal stress of the part is balanced, and the qualified rate of the processed part is improved.
Description
Technical field
The processing method that the present invention relates to the short crimp Z-type of a kind of large curvature titanium-alloy sheet metal, belongs to a kind of machining process.
Background technology
In titanium-alloy sheet metal process, in view of titanium alloy material special nature, its moulding is the difficult point in processing and manufacturing always, during the Z-type titanium-alloy sheet metal that is especially short crimp in the short crimp one of the large curvature of processing side, because part curvature is large, crimp is shorter, in forming process, stress is more concentrated, very easily occurs crackle, thereby causes part to be scrapped, this class part often needs repeated multiple times processing just may obtain certified products, has finally caused its processing and manufacturing cost constantly soaring.
Summary of the invention
The technical problem to be solved in the present invention is to provide the processing method of the short crimp Z-type of large curvature titanium-alloy sheet metal, and the method adopts symmetric double part to process simultaneously, makes the internal stress of part reach balance, thereby improves the qualification rate of part processing.
For overcoming the above problems, concrete technical scheme of the present invention is as follows: the processing method of the short crimp Z-type of a kind of large curvature titanium-alloy sheet metal, comprises the following steps:
1) set up the Mathematical Modeling of Z-type titanium-alloy sheet metal;
2) in Mathematical Modeling, shorter crimp one side is left after process allowance, end face is made as to the plane of symmetry, Z-type titanium-alloy sheet metal is carried out to mirror image processing, obtain technological mathematical model;
3) by technological mathematical model, carry out the manufacturing and designing of mould tire, sheet-metal baiting, then panel beating is carried out to thermoforming;
4) sheet metal component processing is cut apart with the plane of symmetry, removed after surplus, obtain two the qualified parts in left and right.
The short crimp Z-type of this large curvature titanium-alloy sheet metal adopts said method, can make to cause the internal stress of crackle to balance picking out mutually at left and right part, in process, to temperature and pressure, require relatively loose, part qualification rate rises, once can obtain symmetrical two parts, operating efficiency improves greatly simultaneously.
Accompanying drawing explanation
Fig. 1 is the Mathematical Modeling of the short crimp Z-type of large curvature titanium-alloy sheet metal.
Fig. 2 is the technological mathematical model of two symmetrical components.
Fig. 3 is the short crimp Z-type of the large curvature titanium-alloy sheet metal after separation.
Wherein, short crimp one side of 1-; 2-left side part edge; 3-surplus district; The 4-plane of symmetry; 5-right side part edge; Left of 6-; Right of 7-.
The specific embodiment
A processing method for the short crimp Z-type of large curvature titanium-alloy sheet metal, comprises the following steps:
1) set up the Mathematical Modeling of Z-type titanium-alloy sheet metal, as shown in Figure 1;
2) as shown in Figure 2, in Mathematical Modeling, shorter crimp one side is left after process allowance 5mm, end face is made as to the plane of symmetry, Z-type titanium-alloy sheet metal is carried out to mirror image processing, obtain technological mathematical model;
3) by technological mathematical model, carry out the manufacturing and designing of mould tire, sheet-metal baiting, then panel beating is carried out to thermoforming;
4) sheet metal component processing is cut apart with the plane of symmetry, removed after surplus, obtain two the qualified parts in left and right, as shown in Figure 3.
