Abstract

A punch die indexing mechanism of a numerical control press comprises a rack, a rotating shat is mounted on the rack through a bearing device, an upper die frame, a press plate frame and a lower die frame are rotationally connected to the rotating shaft from top to bottom in sequence, a punch die seat is fixedly mounted at the tail end of the lower die frame, the punch die seat is provided with a plurality of punch dies, the upper die frame is provided with corresponding punch rods at the positions exactly facing the punch dies, and the punch rods are fixedly mounted on a fixing seat at the tail end of the upper die frame. The bottom of the lower die frame is fixedly connected with a movable plate, a piston rod of a longitudinal shifting oil cylinder is mounted in a mounting hole of the movable plate through a bearing, and the shifting oil cylinder is fixedly connected to the rack. The upper die frame is fixedly connected with a locating plate, the locating plate is provided with an arc groove, a locating column is in sliding connection with the arc groove of the locating plate, and the locating column is fixedly connected to the rack. A piston rod of a press plate oil cylinder is hinged to the press plate frame, and a cylinder body of the press plate oil cylinder is fixed to the upper die frame. The punch die indexing mechanism of the numerical control press can meet the punching requirements for different hole diameters and is simple in structure, convenient to operate and stable in operation.

Description

technical field [0001] The invention relates to a numerically controlled punching machine, in particular to a workbench capable of installing multiple sets of different punching dies in the numerically controlled punching machine and capable of changing positions and changing dies. Background technique [0002] CNC punching machine is an automatic machine tool equipped with a program control system. The control system can logically process and decode programs with control codes or other symbolic instructions, so that the punching machine can move and process parts. Compared with ordinary Punching machine has high processing efficiency and low labor intensity. In the prior art, most CNC punching machines only have one punching position. If holes with different apertures are to be punched at the same punching position, the punching die needs to be replaced frequently. For some CNC punching machines for processing specific workpieces, there are not many punching hole sizes and...
