Description
Technical Field
[0001] The invention relates to the technical field of electric power tool processing, and in particular to a busbar bending device. Background Art
[0002] During the power construction process, due to the limitation of line discharge distance, high-current products such as copper bars, aluminum bars or iron bars need to be bent for wiring. In order to ensure the bending quality, bending machines are often used to process copper bars, aluminum bars or iron bars according to the actual site conditions.
[0003] For example, in the Chinese patent with patent number 201420044381.9 and invention name "Portable Bending Device", the portable bending device includes a jack and a base, wherein support frames are fixed at opposite ends of the base respectively, the jack is located on the base between the two support frames, and a V-shaped fixed mold is inherently provided between the upper ends of the two support frames, with the raised portion of the fixed mold facing downward, and a movable die matching the raised portion of the fixed mold is movably placed at the upper end of the piston rod of the jack. When in use, the copper bars, aluminum bars and iron bars to be bent are first placed on the movable die, and the operator controls the piston rod of the jack to rise, so that the movable die rises and moves closer to the fixed die. The movable die cooperates with the raised part of the fixed die to bend the copper bar, aluminum bar or iron bar. The operator can control the rising position of the movable die according to the angle requirements of the copper bar, aluminum bar or iron bar at the work site, so that the bending angle of the copper bar, aluminum bar or iron bar meets the requirements. The application is simple to operate and easy to use, and can complete the bending of the copper bar, aluminum bar and iron bar at an angle within 180 degrees. After use, the movable die can be removed from the jack, and the jack can also be removed from the base. The length of each component is short and the volume is small. The base, support frame, jack and movable die can be placed in a tool box for carrying. It is very convenient to carry and suitable for various work sites.
