Premium power press machine supplier 2022? 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. Find extra info at https://www.pressmachine-world.com/power-press-machine. We can provide installation service for all the sold out machines at customer factory. Small machines can be shipped assembled and some big machines must be shipped disassembled. That is why we provide installation service to our customer.
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.
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.
World Precise Machinery (China) is the biggest branch factory of World Group which is focusing on producing and technology researching of power press machines. The original factory was built in 1953 to produce small eccentric punching machines for new China industry. World Group bought this factory in 1998 and expanded the production capacity and the product ranges. Now World can supply power press capacity from 6.3ton to 2500ton, C fame and H frame crank press, tie-rod and mono block type eccentric gear press, hydraulic shearing machine and bending machine (press brake), fiber laser cutting machine and the automatic accessories such as decoiler, straightening machine and roller NC feeder.
