[detailed description of the invention]
Can explain the utility model in more detail by the following examples, the utility model is not limited to the following examples;
A kind of Columnar tooth drill rod head with oblique sludge groove by reference to the accompanying drawings described in 1 ~ 4, comprise bore bit main body 4 and carbide button 8, the upper end of described bore bit main body 4 is provided with and upwards extends and small top and big bottom bullet, be provided with the large taper surface 9 in little bottom, top in the upper end of described bullet or be directly provided with the large taper surface 9 in little bottom, top at the upper end of described bore bit main body 4, the surface uniform of described bore bit main body 4 scribbles epoxy resin, substantially increases the antirust of bore bit and corrosion-resistant function, further, described taper surface 9 is laid with at least three alloy perforations 3, carbide button 8 is respectively equipped with in described alloy perforation 3, it is interference fit when wherein carbide button 8 is connected with alloy perforation 3, exposed face after described carbide button 8 is arranged on alloy perforation 3 evenly scribbles epoxy resin, described epoxy resin is environment-friendly epoxy resin, wherein the use amount of environment-friendly epoxy resin is each bore bit 3.5 ~ 3.6g, bore bit main body 4 between every two carbide buttons 8 is provided with oblique sludge groove 1, at least one oblique sludge groove 1 that bore bit main body 4 upper end is arranged is provided with the through weep hole 2 to inlet opening 6, weep hole 2 and alloy perforation 3 is respectively equipped with on the upper end of bore bit main body 4, described weep hole 2 is communicated with the inlet opening 6 be arranged in the middle part of bore bit main body 4, wherein said oblique sludge groove 1 is 30 ° ~ 35 ° with the angle of the included angle A 5 of bore bit main body 4, and described oblique sludge groove 1 is 7 ° ~ 10 ° with the angle of the included angle B 7 of bore bit main body 4.
The utility model is in specific implementation process, and for D40 product, the diameter being arranged on the weep hole 2 of bore bit main body 4 upper surface is φ 5mm, and the diameter being arranged on the weep hole 2 on oblique sludge groove 1 is φ 6mm, and the diameter of alloy perforation 3 is φ 9mm.
The Columnar tooth drill rod head with oblique sludge groove described in the utility model is relative to the advantage of existing bore bit:
1, the straight sludge groove trousers body existing 120 ° divided equally, the oblique sludge groove 1 being designed to similar spiral bit designs, and namely makes it have certain angle of inclination when processing straight trough;
2, wherein tiltedly sludge groove 1 process forming causes primarily of the synthesis of both direction angle, namely included angle A 5 and included angle B 7 are synthesized, by putting into practice confirmation in a large number, the angle of included angle B 7 can reach good row's powder effect at 7 ° ~ 10 ° and the angle of included angle A 5 at the oblique sludge groove 1 that 30 ° ~ 35 ° any combination are formed;
