Quality world press machine provider right now? Hydraulic transmission is adopted, and the slider part is composed o slide, an oil cylinder and a fine-tuning structure of a mechaicl stoper. Te left and right oil cylinders are fixed on the frame, the piston (rod) drives the slider to move up and down through hydraulic pressure, and the mechanical stop is controlled by the numerical control system to adjust the value; Workbench part: controlled by the button box, the motor drives the stopper to move back and forth, and the moving distance is controlled by the numerical control system. The minimun reading is 0.01 mm (the front and rear positions have travel switch limits). See more info at power press machine manufacturers.
In order to choose the lowest onnage specifiction,itis best to plan for a bening radus larger than the thickness of the material, and use the free bending method as much as posible When the bending radius is large, it often does not affect the quality of the finished part and its future use. Bending accuracy requirements are a factor that needs to be carefully considered. It is this factor that determines the need to consider a CNC bending machine or a manual bending machine. If the bending accuracy is required to be ±1 and cannot be changed, the CNC machine must be focused.
Through this partnership of shared experience and ideas, we are confident that we can realize your current and future requirements on WORLD press machine. 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.
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. See even more info at https://www.pressmachine-world.com/.
