Power press machine factory in China? World has been committed to the development and production of power press machines since it was established in 1953. More than 100 experienced engineers are working in the three R&D centers, one in Shanghai, one in factory and another one in Ningbo. Discover even more information at bending press machine. Through this partnership of shared experience and ideas, we are confident that we can realize your current and future requirements on WORLD press machine.
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.
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.
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.
The steady expansion of e-mobility and the legal regulations relating to conventional combustion engines are subjecting the traffic and transport sectors to comprehensive change. To reduce emissions, for example, lighter car bodies and vehicle componens are needed. In addition, crash safety also plays a role, because the accommodationof heay bateries in a vehicle requires appropriately designed body structures that take an accident scenario into account. While fiber composites are sometimes used in smll series in this context, materials such as high-stregth steel and aluminum are asserting themselves in large series construction with cntinuous refinement. n adition to the compatively lowsost, een reclilt s a significant advantage of metallic materials. However, their further development often poses new challenges for the processing procedures and the machines used. Read additional info on https://www.pressmachine-world.com/.
