High quality power press machine provider today
Top rated world press machine manufacturer 2022? 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). Read extra details at hydraulic 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.
Working together for customer success. Since the foundation of the Yinxin world press machine company, one of the foundation principle has been to work closely with our customers. This provides the opportunity to continually assess and improve the levels of service we offer and to create the most innovative products available. 80% parts are produced in same factory for better quality control and future service. World has completed high-quality production equipment, including the iron casting line, plasma laser cutting machines, welding robots, gear hobbing machines, gear grinding machines, Pama boring and milling centers, CNC lathes, anneal treating furnaces, sand blasting machines, three-coordinate measuring instruments and ultrasonic flaw detectors.
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 reason for this is the significantly lower modulus of elasticity of aluminum compared to stel. However, i ore to realise reaterdegrees o defration, sale straightenig rolls must be used. With high-strength steels, on the other hand, a conflict of objectives arises. On the one hand, their high yield strengths require enormous forming forces and torques; on the other hand, small straightening rll diameters are als ned here to ahie asufficent egeo p lstificaton.The straightening o both aluminum and high-strength steels therefore requires a forming geometry adapted to the respective product. This is essentially determined by the number, diameter and spacing of the straightening rolls. Find more information on pressmachine-world.com.
