Now, in this industrial country, the CNC V Grooving machine has become a very common device. So, what is the use of the V grooving machine ? What is the future development of CNC V grooving machine? Let's take a closer look at the two major categories to elaborate.
1.Process characteristics of V-grooving of thin metal sheets before bending. The curved edge of the workpiece after bending is small and has no radius. The bending process shows that the radius of the edge of the workpiece after bending is proportional to the thickness of the workpiece being bent, because V is thin on the metal sheet. After the groove is formed, the thickness of the remaining sheet material is only half of the thickness of the original sheet material, or even smaller, so that the radius of the edge of the workpiece after the bending is also proportionally reduced. Moreover, since the thickness of the remaining sheet material after the V-shaped groove is small, the deformation force at the time of bending is also small, and the diffusion does not affect the unbent area, so that the surface of the bent metal sheet workpiece has no refraction. This will meet the special requirements of high-end decoration in hotels, restaurants, restaurants, commercial buildings, banks, airports and other places.
2.The bending force required to reduce the bending of the sheet material is known from the bending process. The bending force of the sheet material is also proportional to the thickness of the sheet material to be bent, and the metal sheet material is V-shaped before bending. After the groove, the thickness of the remaining sheet is about half of the thickness of the original sheet, or smaller, so that the bending force required for the sheet bending is correspondingly reduced, so that the long sheet is on the smaller tonnage bending machine. It is also possible to bend. It can reduce equipment investment and save energy.
3.Some special materials can be bent into rectangular tubes on a common bending machine with a universal mold. This type of material cannot be bent on a common bending machine, or a special design of a complicated mold is used to complete the work. However, by controlling the depth of the V-groove of the thin metal sheet material, it is possible to bend the special type of the bent material on the ordinary bending machine by using a general-purpose mold. The specific method is: the thickness of the remaining sheet material of the V-groove in the last bending process is controlled to about 0.3 mm, so that the rebound angle of the bending process is small, and the rectangular tube will not rebound and deform after molding.
4.Positioning the length of the curved side before bending The V-shaped planing groove for the thin metal sheet can be used to pre-position the length of the curved side before bending, and then follow the pre-scribed V on the bending machine. The type of wire groove is bent, so as to ensure the accuracy of the length of the bent side, and can replace the back material function of the numerical control bending machine. Of course, the premise is that the positioning accuracy of the V-type planer must reach ±0.05 mm.
