Abstract
The utility model relates to a thin plate drill with permanent magnets. The thin plate drill with the permanent magnets comprises a twist drill. A drill point is ground on the top end of the twist drill. Two outer edges are arranged on the left side and right side of the drill point of the twist drill. An outer edge point is arranged at the top end of the outer edge. The drill point is 1 millimeter to 1.5 millimeters higher than the outer edge point. A plurality of concave grooves are arranged up and down in a chip groove of the twist drill in a staggered mode. Each permanent magnet which has the same size as each concave groove is fixedly arranged in each concave groove. According to the thin plate drill with the permanent magnet, the drill point drills into a workpiece first to play a role in centering. Two sharp outer edge points cut the middle portion out quickly to obtain a required hole. The thin plate drill with the permanent magnets is adopted to drill a thin plate quickly and cleanly, safely and reliably. The thin plate drill with the permanent magnets has the advantages of being simple in structure and convenient to manufacture. The phenomena of polygon, orifice rag, large burr and the like are avoided.
Description
Technical field
The utility model is a kind of drill bit, and a kind of thin plate that bores sheet steel bores specifically.
Background technology
Hole at the thick sheet metal of 0.1～1.5mm, black sheet iron, thin aluminum sheet, sheet brass and sheet copper, can not use common drill bit, otherwise the hole that gets out will occur not justifying, becoming polygonal, aperture overlap, burr very large, even the thin plate torsional deformation, and the hole is torn.Large thin plate is difficult to be fixed on the lathe, if grasp thin plate boring, when saturating with the firm brill of the apex point of common fluted drill, drill bit loses the ability of centering, workpiece is shaken, blade is cut suddenly more, penetrates thin plate, and cutting force is anxious to be increased, easily make broken drill or hand steered not living, cause the accident, and the chip that cuts blocks processing work easily, cause a deviation.
Summary of the invention
In order to address the above problem, the utility model provides a kind of thin plate with permanent magnet to bore, and it is neat and tidy, safe and reliable to bore thin plate with it.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
The utility model is that a kind of thin plate with permanent magnet bores, and comprises fluted drill, grinds an apex point on the top of fluted drill, and on fluted drill, the left and right sides of apex point forms two outer rim swords, the top of outer rim sword is the outer rim blade tip.Several grooves that are crisscross arranged up and down on the chip area of fluted drill are fixedly installed the permanent magnet identical with each groove size in each groove.
Further improvement of the utility model is: apex point is higher than outer rim blade tip 1-1.5 millimeter.
The beneficial effects of the utility model are: thin plate of the present utility model bores, apex point is cut first workpiece during brill, play certralizing ability, two sharp cylindrical blade tips cut off the centre of the workpiece of needs cutting rapidly, obtain desired hole and bore the neat and tidy of thin plate with it, safe and reliable, the permanent magnet that arranges on the drill bit adsorbs the chip that cuts, in order to avoid shelter from the workpiece that needs cutting, cause other accident.
The utility model is simple in structure, and is easy to make, the phenomenons such as polygonal, aperture overlap, burr be very large can not occur.
Description of drawings
Fig. 1 is structure chart of the present utility model.
Wherein: 1-fluted drill, 2-apex point, 3-outer rim sword, 4-cylindrical blade tip, 5-groove, 6-permanent magnet.
The specific embodiment
In order to deepen that understanding of the present utility model is described in further detail the utility model below in conjunction with drawings and Examples, this embodiment only is used for explaining the utility model, protection domain of the present utility model is not consisted of to limit.
Shown in Fig. 1, the utility model is that a kind of thin plate with permanent magnet bores, comprise fluted drill 1, grind an apex point 2 on the top of described fluted drill 1, on described fluted drill 1, the left and right sides of described apex point 2 forms two outer rim swords 3, the top of described outer rim sword 3 is outer rim blade tip 4, and described apex point 2 is higher than described outer rim blade tip 4 1-1.5 millimeters.Several grooves 5 that are crisscross arranged up and down on the chip area of described fluted drill 1 are fixedly installed permanent magnets 6 identical with described each groove 5 size in described each groove 5.
Thin plate of the present utility model bores, and apex point is cut first workpiece during brill, plays certralizing ability, and two sharp cylindrical blade tips cut off the centre of the workpiece of needs cutting rapidly, obtain desired hole, and it is neat and tidy to bore thin plate with thin plate, safe and reliable.The permanent magnet that arranges on the drill bit adsorbs the chip that cuts, in order to avoid shelter from the workpiece that needs cutting, causes other accident.
The utility model is simple in structure, and is easy to make, the phenomenons such as polygonal, aperture overlap, burr be very large can not occur.
