Press brake punch/die is divided into upper and lower molds, which are used for sheet metal stamping forming and separating molds. The mold for forming has a cavity, and the mold for separating has a cutting edge. The punch/die of the press brake machine has a great influence on the accuracy of the
1. Different structural principlesThe design principles of the two models are different, resulting in different structures for ensuring synchronization on both sides of the bending slider. The torsion axis bending machine uses a torsion axis to connect the left and right swing rods to form a torsion
Conventional bending sequence1. Short side first and long side first: Generally speaking, when all four sides are bent, folding the short side first and then the long side is beneficial to the processing of the workpiece and the assembly of the bending mold.2. Peripheral first and then middle: Under
The CNC bending machine is important equipment in sheet metal processing, and its work accuracy directly affects the bending accuracy of the workpiece. In the bending process of the workpiece, the press brake machine is subjected to the greatest force at both ends of the slider, and the reaction for
The press brake bending machine mainly performs straight-line bending of the plate. By using simple molds and process equipment, the metal sheet can be pressed into a certain geometric shape, and it can also be processed by stretching, punching, punching, and pressing corrugation. In actual producti
