The technical scheme that the problem that the utility model is the above-mentioned proposition of solution adopts is:
A kind of formwork tapper, comprise drilling rod 1, connecting bolt 2, pallet 3, teeth 4, bite B5, cutting blade 6, drill bit 7 and bite A8, drilling rod 1 is connected with the geometry center of circle of disc pallet 3 by connecting bolt 2, pallet 3 top edge has teeth 4 uniformly at intervals, it is inner that bite B5, cutting blade 6 are arranged on pallet 3, and bite B5 is along pallet 3 radial direction and cutting blade 6 company of edge, and drill bit 7 one end is arranged on the pallet 3 geometry center of circle, drill bit 7 other end inlays bite A8, outside drill bit 7, have spiral yarn shaped chip area 9 around axis direction.
Described drilling rod 1 is regular polygon metal drill pipe, is connected more firm, not easily skids and come off with machine shaft.
Described pallet 3 top edge offers right-angled trapezium groove 10 at equal intervals, and groove 10 is positioned at teeth 4 side, is convenient to the break flour discharge tray that will produce.
Described bite B5 is triangular prism shaped metal cutter, and cutting effect is better.
Described cutting blade 6 is fan-shaped metallic cutting blades, is smashed by the scrap of generation, is convenient to scrap and discharges from groove.
Described bite B5, cutting blade 6 are distributed in pallet 3 for several, strengthen fluting effect.
Described drill bit 7 is solid truncated cone-shaped metal bit, and the tapering of drill bit 7 is 1:15, progressively reaming, and drilling effect is better.
Operation principle of the present utility model: the drilling rod of formwork tapper is arranged on the machine shaft of corresponding adaptation, bite A is aimed at the appointment position of opening of the composite insulation boards that will offer, closed motor switch carries out perforate operation; Drill bit stretches in the process of composite insulation boards, and teeth, bite B, cutting blade offer circular groove around the hole that composite insulation boards is offered, when circular groove reach design offer the degree of depth after stop electric machine rotation.
The beneficial effects of the utility model are: 1, structure is simple, easy to operate, can either carry out perforate operation to common templates, can carry out perforate, fluting two operations again simultaneously, save a large amount of labor hour to composite insulation boards.2, drilling rod is regular polygon metal drill pipe, is connected more firm, not easily skids and come off with machine shaft.3, pallet top edge offers right-angled trapezium groove at equal intervals, and groove is positioned at teeth side, is convenient to the break flour discharge tray that will produce.4, bite B is triangular prism shaped metal cutter, and cutting effect is better.5, cutting blade is fan-shaped metallic cutting blades, is smashed by the scrap of generation, is convenient to scrap and discharges from groove.6, bite B, cutting blade are distributed in pallet for several, strengthen fluting effect.7, drill bit is solid truncated cone-shaped metal bit, and the tapering of drill bit is 1:15, progressively reaming, and drilling effect is better.
