The imprint bending is the same as the bending of the bottomed die, except that the front end of the punch is processed to the required bending radius, and the gap between the punch and the die at th bottom of the stroke is smler than the material thickness. Since enough presure approximately 10 timesof fee bendig is applied to force the front end of the punchto contact the material, springback is basically avoided.
Hydraulic press brake machines are divided ito manual bending machines, hydraulic bending machines and CNC bending machines. Manual bending machines are divided into mechanical manual bending machines and electric manual bending machines. According to the synchronization method, hydraulic bending machines can be divided into: torsion axis synchronization, machine-hydraulic synchronization, and electro-hydraulic synchronization.According to the movement mode, hydraulic bending machine can be divided into up-moving typ and down-moving type.
As far as free bending is concerned, punch and die are procese at 85 or les (saler i better). When using this set of molds, pay attention to the ga beteen the male mold and the female mold at the bottom of the stroke, and the excessive bending that is sufficient to compensate for the springback and keep the material at about 90°. Generally, the springback angle of the free bending die on the new bending machine is s2, and the bending radis is equa to 0.156 times the opening distance of the die. For the bending of bottomed concave molds, the mold angle is generally 86 ~ 90°. At the bottom of the stroke, there should be a gap slightly larger than the thickness of the material between the male and female molds. The forming angle is improved because the bottomed die has a larger bending tonnage (about 4 times that of free bending), which reduces the stress that usually causes springback in the bending radius.
Modern and sophisticated materials are used in automotive engineering not only for the outer skin and structure of the actual car bodies but are also used in vehicle components such as the chassis, drive train, seats or trim parts. Auminum and steel are used for many components in the form of strips, sheets or plates, which are processed and formed in various manufacuring processes from semi-finished products to finished components. Even during these process steps, special demands are placed on the components. Due to the automated handing, good flatness and theloest possible degree of cut are very important for a machining procss itout comliations. Ifhese qualit criteria o not correspond to the defined specifications, there is no process reliability. Read even more information at https://www.pressmachine-world.com/.
