Even if there are shelves full of molds, don’t assume that these molds are suitable for the newly purchased machine. The wear of each mold must be checked by measuring the length from the front end of the punch to the shoulder and the length between the shoulder of the female mold. For conventional ols, the deviation per foot should be about t0.001 inches, and the total length deviation should not be greater than t0.005 inches. As for the precision grinding mld, the accuracy per foot should be ±0.0004 inches, and the total accuracy should not be greater than ±0.002 inches. It is best to use fine grinding molds for CNC bending machines, and conventional molds for manual bending machines.
Main features: Adopt all-steel welded structure, with sufficient strength and rigidity; Hydraulic drive, the oil cylinders at both ends of the machine tool are placed on the sliding block to directly drive the sliding work; The slider synchronization mechanism adopts torsion shaft for forced synchronization; Using mechanical block structure, stable and reliable; The stroke of the slider can be adjusted quickly by motor, fine-tuned manually, and the counter is displayed; Oblique wedge-type deflection compensation mechanism to ensure higher bending accuracy.
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 even more information at pressmachine-world.com.
