Titanium plate blanking and forming cleaning
Titanium plate blank blanking
There are many similarities in the preparation methods of wool used in various sheet metal parts. Due to the use of titanium plate thickness is generally below 2 mm, and the thickness of 1. There are very few parts above 5 mm, so the discharge of titanium plate can be carried out with the existing equipment at room temperature.
When cutting, should pay attention to make the wool edge as smooth as possible, especially to prevent the edge of cracks, gnaw and shear marks and other defects, in the shear plate should pay more attention.
Wool should be deburred and sharp edges removed before forming. Because the titanium plate is sensitive to crack growth, this work is very important to eliminate stress concentration and prevent the wool from cracking and scratching the mold during forming. Can be used to file, belt grinding or sandpaper burr or polishing.
It should be noted that no matter which method of blanking, in the line, only use no pollution of ink and pen, in wool is not allowed to make steel, only make offset printing or specially equipped with labels.
Oil removal and cleaning before forming
Grease, grease, or other dirt should be removed from the surface before any thermal molding so as not to contaminate the titanium during heating. In addition, oxides on the surface of the wool reduce the plasticity of the material and should be removed before forming. Therefore, in order to reduce various influences in the atmosphere, vacuum quenching furnace and vacuum annealing furnace are generally used for heating. Inert gas in the vacuum furnace can protect titanium and titanium alloy materials from pollution in the heating process.
