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 press brake machines are divided ito manual bending machines, hydraulic bending machines and CNC bending machines. Manual bending machines are divided into mechanical manual bending machines and electric manual bending machines. According to the synchronization method, hydraulic bending machines can be divided into: torsion axis synchronization, machine-hydraulic synchronization, and electro-hydraulic synchronization.According to the movement mode, hydraulic bending machine can be divided into up-moving typ and down-moving type.
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.
Aluminum and high-strength steels, for example, place special demands on the individual processing steps. One factor that has a major influence on the quality of the end product is the straightening of the respective metal. In a straightening machne consisting of several stagered straighngos,the coilcrvatre o the starting matril is elmnated. In adition, any edge or centre waves in the strip material can be compensated for, using suitable machines. The aim here is to achieve the lowest possible and most homogeneus resiu sres state in order to maintain te flatness of the material during subsequent cutting processes. n lentr mesur fo th eciecy of a straighten roessis te dere of platification of the respective metal, which describes the proportio o he material os-section that is plastically deforme uring straightening. With the same yield strength and material hickness, aluminum requires significantly greater degrees of deformation than steel to achieve comparable plastification.
