Punch die indexing mechanism of numerical control punch press

Abstract

A punch die indexing mechanism of a numerical control punch press comprises a rack. A rotating shaft is mounted on the rack through a bearing device, the rotating shaft is in rotating connection with an upper die frame, a pressing plate frame and a lower die frame from top to bottom in sequence, a punch die seat is fixedly mounted at the tail end of the lower die frame, a plurality of punch dies are mounted on the punch die seat, corresponding punching rods are arranged at the positions, directly facing the punch dies, of the upper die frame, and the punching rods are fixedly mounted on a fixing seat at the tail end of the upper die frame. A movable plate is fixedly connected on the bottom of the lower die frame, the piston rod of a longitudinal shifting oil cylinder is mounted in a mounting hole of the movable plate through bearings, and the shifting oil cylinder is fixedly connected on the rack. A locating plate is fixedly connected on the upper die frame, the locating plate is provided with an arc-shaped groove, a locating column is in sliding connection with the arc-shaped groove of the locating plate, and the locating column is fixedly connected on the rack. One end of a piston rod of a pressing plate oil cylinder is hinged to the pressing plate frame, and the cylinder body of the pressing plate oil cylinder is fixed on the upper die frame. The punch die indexing mechanism of the numerical control punch press can meet hole punching requirements of 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...
