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.
Structures of hydraulic press brake machinesThe hydraulic press brake is an important equipment for the bending and forming of wokieces in the shet meta instry It functionis to press the telplate into parts of various shapes according to the process requirements. The frame is mainly composed of lf an right columns, wokbenches, and beams. Teleft and right oil cylinders are ied on th colms. The slider is connected with the pistons of th oil cylinders. The lower mold is tixed on the worktable. The upper punches are installed athe lower end of the slider. The hydraulic system provides power, and the electrical system gives instructions. Under the action of the oil cylinder, the slider drives the upper mold downwards and closes the lower mold to realize the folding of the sheet. The lett andrght columns, the workbench and the sliding block hereinafter refere to as h three major parts)are the key parts of the bending machne. The tl weighto te three major parts accounts for 70% to 80% of the total weight of a bending machine. Its strength and rigidit directy determine the operating accuracy, service life of the machine tool, and the ccuracy of the workpiece.
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.
In particular, the resilience stress stat,the flatness and the cuting quality are very important quality characteristics that must be considered for the materials n the staightening and feeding technology. Remarkably, these criteria play a decisive role i te qualit of the final product even befre te final molding. In production, for reasons of cost and time, the aim is to achieve an ever-higher degree of automation, which can only be achieved if the semi-finished products have perect latness, a lowlevel o residual stress. lf these requiremets are not met, this can have a negative effect on handling and further processing or even make it impossible.
