press brake also known as a brake press or just brake, is a machine tool for bending sheet and plate material, most commonly sheet metal. A press brake is a metalworking machine that allows the bending of sheet metal. A cornice press brake only allows for simple bends and creases, while a box-and-pan press brake also allows one to form box and pan shapes. It is also known as a bending machine or bending brake. The presss brake consists of a flat surface onto which the material is placed, and a clamping bar which will come down and hold the material firmly during the bend. This clamping action may be manual, automatic or operated using a foot pedal. The front, gate-like, plate of the machine is hinged and may be lifted, forcing the material extended over a straight edge to bend to follow the plate. press brake The bends can be to any angle up to a practical limit of about 120 degrees, somewhat more in the case of a bar folder. If the area to be bent is narrow enough, a sharper bend (e.g., for a hem) can be made by inserting the bend under the clamping bar and lowering brake A press brake can be described by basic parameters, such as the force or tonnage and the working length.Additional parameters include the amplitude or stroke, the distance between the frame uprights or side housings, distance to the backgauge, and work height. The upper beam usually operates at a speed ranging from 1 to 15 mm/ brake The hydraulic press brake machine: Series WC67K principal machine is adopted. E20economic double axis CNC system is adopted with high ratio of performance against price. press brake Ram stroke and back-gauge can automatically operates with function of muti phase programming. Function of one-way and mutual positioning can effectively eradicate screw gap.
