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.
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).
Carefully consider the material grade and the maximum processing thickness and lengh. If most of the work is lowcarbon steel with a thickness of 16 gauge and a maximumlengh of 10 feet (3.048 meters), then the free bending force does not need to be greater than 50 tons. However, f yu are engaged in alarge number of bottomed die forming, perhaps a 160-ton machine toolshould be considered. Assuming that the thickest material is 1/4 inch, a 10-ot re bending requires 0 tos, and a botomed die bending (corected bendg) requre atleast o00tos. If mos prtsare 5feet or shorter, the tonnage is almost halved, which greatly reduces the cost of purchase. The length of the part is very important for determining the specifications of the new machine.
The experts of the world machinery have been dealing with the numerical simulation of forming processes in straightening machines for many years. For this reason, powerful simulation orogrammes are available today with which optimal configurations can be determined for the respective applications. The software has been validated by means of extensive experimental investigations so that the optimum straightening roll diameters can be determined for a specific area of application.
