For realizing above object, technical solution of the present utility model is: a kind of punching multiple holes on square tube crush-cutting mould that breaks, comprise base and pressed sheet, described base and pressed sheet are parallel to each other, described pressed sheet below is provided with a upper bracket, upper bracket below is fixedly connected with the cutter of vertical sensing base, on base, on the position corresponding with cutter, there is undersetting, undersetting is made up of symmetrical left support abutment and right support abutment, the cross section of left support abutment is " recessed " font, and the spacing between left support abutment and right support abutment is greater than the thickness of cutter.
The top of described cutter is " V " font, and the acute angle angle at the top of cutter is between 30 degree to 70 degree.
Between described base and pressed sheet, be provided with at least one group of punching press positioner, punching press positioner comprises and is vertically connected to the guide pin bushing of pressed sheet below and is vertically connected to the guide pillar on base, guide pin bushing sensing guide pillar.
Below, described undersetting bottom is provided with the feed opening that runs through base, and the width of feed opening is greater than the thickness of cutter.
Between described left support abutment and right support abutment, fix by card article.
The utility model compared with the existing technology has following beneficial effect:
1, upper bracket, undersetting and cutter in the design, have been adopted, and undersetting is made up of left support abutment and right support abutment, the cross section of left support abutment is " recessed " font, spacing between left support abutment and right support abutment is greater than the thickness of cutter, when use, square tube is placed on the Baltimore groove being formed by left support abutment and right support abutment, drive pressed sheet by punch press, cutter moves downward, and completes cut-out, simple in structure, easy to use.
2, in the design, used guide pin bushing and guide pillar, both cooperations are protected the precision of punching press.
3, in the design, below, undersetting bottom is provided with the feed opening that runs through base, and the width of feed opening is greater than the thickness of cutter, and the waste material that punching press produces like this can be discharged via feed opening.
