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 present invention relates to the processing method of the short crimp Z of a kind of big curvature Type Titanium Alloy sheet metal part, belong to a kind of machining process.
Background technology
In titanium alloy sheet metal part process, in view of the titanium alloy material special nature, its moulding is the difficult point in the processing and manufacturing always; Especially when the short crimp one of which of the big curvature of processing side was the Z Type Titanium Alloy sheet metal part of short crimp, because the part curvature is big, crimp was shorter; Stress is more concentrated in the forming process, crackle very easily occurs, thereby causes part to be scrapped; This type part often needs repeated multiple times processing just possibly obtain certified products, has finally caused its processing and manufacturing cost constantly soaring.
Summary of the invention
The technical problem that the present invention will solve provides the processing method of the short crimp Z of big curvature Type Titanium Alloy sheet metal part, and this method adopts the 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 following: the processing method of the short crimp Z of a kind of big curvature Type Titanium Alloy sheet metal part may further comprise the steps:
1) sets up the Mathematical Modeling of Z Type Titanium Alloy sheet metal part;
2) in Mathematical Modeling, will shorter crimp one side leave process allowance after, end face is made as the plane of symmetry, Z Type Titanium Alloy sheet metal part is carried out mirror image processing, promptly obtain technological mathematical model;
3) carry out the manufacturing and designing of mould tire, panel beating blanking by technological mathematical model, again panel beating is carried out thermoforming;
4) sheet metal component that processes is cut apart with the plane of symmetry, after the removal surplus, two qualified parts about promptly obtaining.
The short crimp Z of this big curvature Type Titanium Alloy sheet metal part adopts said method; Part has balanced picking out each other in the left and right sides can to make the internal stress that causes crackle; Require loose relatively to temperature and pressure in the process; The part qualification rate rises, and once can obtain symmetrical two parts simultaneously, and operating efficiency improves greatly.

Fig. 1 is the Mathematical Modeling of the short crimp Z of big curvature Type Titanium Alloy sheet metal part.
Fig. 2 is the technological mathematical model of two symmetrical components.
Fig. 3 is the short crimp Z of the big curvature Type Titanium Alloy sheet metal part after separating.
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; 6-left side part; The right part of 7-.
The specific embodiment
The processing method of the short crimp Z of a kind of big curvature Type Titanium Alloy sheet metal part may further comprise the steps:
1) set up the Mathematical Modeling of Z Type Titanium Alloy sheet metal part, as shown in Figure 1;
2) as shown in Figure 2, in Mathematical Modeling, will shorter crimp one side leave process allowance 5mm after, end face is made as the plane of symmetry, Z Type Titanium Alloy sheet metal part is carried out mirror image processing, promptly obtain technological mathematical model;
3) carry out the manufacturing and designing of mould tire, panel beating blanking by technological mathematical model, again panel beating is carried out thermoforming;
4) sheet metal component that processes is cut apart with the plane of symmetry, after the removal surplus, two qualified parts are as shown in Figure 3 about promptly obtaining.
