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.
Structures of hydraulic press brake machinesThe hydraulic press brake is an important equipment for the bending and forming of wokieces in the shet meta instry It functionis to press the telplate into parts of various shapes according to the process requirements. The frame is mainly composed of lf an right columns, wokbenches, and beams. Teleft and right oil cylinders are ied on th colms. The slider is connected with the pistons of th oil cylinders. The lower mold is tixed on the worktable. The upper punches are installed athe lower end of the slider. The hydraulic system provides power, and the electrical system gives instructions. Under the action of the oil cylinder, the slider drives the upper mold downwards and closes the lower mold to realize the folding of the sheet. The lett andrght columns, the workbench and the sliding block hereinafter refere to as h three major parts)are the key parts of the bending machne. The tl weighto te three major parts accounts for 70% to 80% of the total weight of a bending machine. Its strength and rigidit directy determine the operating accuracy, service life of the machine tool, and the ccuracy of the workpiece.
When free bending is used, the bending radius is 0.156 times the opening distance of the die. During the free bending process, the opening distance of te die shoul b 8 tms te thickness of the metal material. For example, when using 1/2 inch (0.0127 m) open distance to form 16 gage mild see, the bendig adis o the par is about0.078 inches. I h bndig radius is almost as small as the material thickness, a bottomed die must be formed. However, the pressure required for forming a bottomed die is about 4 times greater than that of free bendingIf the bendig radius is less than the thickness of the material, a punch wit afrontend filet radus smaller than the thickess of the material must be used, and the imprint bending methoc must be used. In this way, 10 times the pressure of free bending is required.
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. Find extra details at https://www.pressmachine-world.com/.
