Abstract

The invention discloses a punching die for a bottom cover of a lamp pole flange. A stripper plate is arranged between a fixed die below and a moving die above, two positioning blocks are arranged on the fixed die, and the stripper plate is positioned on the positioning blocks. Along different directions of flanges with two different central distances putting in the die, the punching die for the bottom cover of the lamp pole flange can machine the flanges with two different central distances, and can punch four holes at one time, so that the size precision of hole location and hole pitch is high, the technology is optimized, and the working hours are reduced.

Description

technical field [0001] The invention relates to a mold capable of processing holes on the flange bottom cover of a light pole, in particular a mold capable of punching multiple holes at one time. Background technique [0002] At present, the method of punching the flange of the light pole is generally to put each corner of the flange plate into a small-tonnage punching machine, and punch a hole each time, and a flange needs to be punched four times in total. But its disadvantage is that it wastes man-hours, and the size error of the punched hole is relatively large. Contents of the invention [0003] In order to overcome the disadvantages of the existing lamp post flange punching, which wastes man-hours and the size error of the punched hole is relatively large, the invention provides a lamp post flange bottom cover punching die, which can process two types of lamps with different center distances. Flange, and four holes are punched at one time, the dimensional accuracy o...
