Technical Field

[0001] The utility model relates to the field of bus duct side plate processing equipment, in particular to a numerical control punching machine which is convenient for processing multi-shaped holes on a bus plate. Background Art

[0002] The bus duct is a closed metal device composed of copper and aluminum busbars. It is used to distribute high power to various components of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk projects. The busbar is an essential component of the bus duct, which mainly plays a bearing role. In order to play a connecting role, the busbar is generally punched. The existing punching operation is generally achieved by a punching machine. Most of the existing punching machines are linear movable punching machines, such as a busbar duct punching machine disclosed in patent CN220461896U. The general principle is to feed the busbar plate to a storage table, and then use a punching structure to punch the busbar plate. However, the punching structure thereon can only punch holes of a single shape, and cannot punch holes of other shapes. When punching holes of different shapes is required, the existing technology generally moves the busbar plate to a specific station for processing, or replaces the punch. It is troublesome to replace the punch in the above technology, and the replacement punch cannot be matched with the hydraulic cylinder accordingly, which makes the replacement very inconvenient or even impossible.

The stamping component 3 specifically includes a gantry 301, which is arranged on the workbench 1 and located at the left end of the first guide rail 2. A support platform 302 is horizontally arranged between the two columns of the gantry 301. A stamping die plate 303 is arranged on the upper surface of the support platform 302. The stamping die plate 303 and the support platform 302 are provided with punching holes and punching grooves 305 at intervals along the length direction of the first guide rail 2. Specifically, in the present embodiment, the punching groove 305 is located on the right side of the punching hole. A lifting drive member 308 is arranged on the support platform 302. The lifting drive member 308 is specifically arranged above the stamping die plate 303 through a bracket, that is, higher than the table surface of the support platform 302. The lifting drive member 308 is connected to a knife seat 307, and the knife seat 307 has a punching knife The punching knife 304 mounting position and the notching knife mounting position are arranged at intervals in the left-right direction, and the notching knife mounting position is located on the left side of the punching knife 304 mounting position.
