Problems solved by technology
[0003] The CNC bending machine forms the plate into the designed bending angle. According to the thickness of the plate and the bending angle, different molds need to be replaced to work. However, the upper mold of the general bending machine is fixedly connected to the pressure head through multiple bolts. When the upper mold is working, the bolts are easily bent by the downward shear force, which makes it difficult to replace the upper mold. For this reason, we propose a CNC bending machine for the production of general electrical equipment.

The machine comprises a rack and a hydraulic cylinder, the hydraulic cylinder is located at oneside of the rack, the output end of the hydraulic cylinder is connected with a pressure head, an upper die is arranged at the lower end of the pressure head, and a first connecting plate is fixed tothe outer surface of the upper end of the upper die; and a dovetail sliding strip is fixed to the upper end of the first connecting plate, a dovetail sliding way matched with the dovetail sliding strip is formed at the lower end of the pressure head, first arc-shaped rings are symmetrically hinged to the surface of the first connecting plate, a workbench is arranged at the lower end of the upper die, a lower die is arranged at the upper end of the workbench, and a bending groove is formed in the surface of the lower die. The upper die is convenient to replace, the operation is simple, and thereplacement speed is higher.
Description
technical field [0001] The invention relates to the technical field of bending machines, in particular to a numerically controlled bending machine for the production of general electrical equipment. Background technique [0002] The CNC bending machine uses the equipped mold (general or special mold) to bend the metal sheet in the cold state into workpieces of various geometric cross-sectional shapes. It is a sheet metal forming machine designed for cold-rolled sheet metal processing, and is widely used in sheet metal bending processing in industries such as automobiles, aircraft manufacturing, light industry, shipbuilding, containers, elevators, railway vehicles, and electrical equipment. [0003] The CNC bending machine forms the plate into the designed bending angle. According to the thickness of the plate and the bending angle, different molds need to be replaced to work. However, the upper mold of the general bending machine is fixedly connected to the pressure head thr...
