Abstract
The invention relates to a sheet drill with a permanent magnet. The sheet drill comprises a twist drill, wherein a drill point is formed at the top end of the twist drill by grinding; two outer-edge blades are formed on the left side and the right side of the drill point on the twist drill; outer-edge blade points are arranged at the top ends of the outer-edge blades; and the drill point is higher than the outer-edge blades by 1-1.5 mm. A plurality of grooves are formed in a chip discharging groove of the twist drill in a vertically-staggering way; and a permanent magnet of which the size is identical with that of each groove is fixedly arranged in each groove. According to the sheet drill disclosed by the invention, during drilling, the drill point cuts into a workpiece firstly for centering; the middle of the workpiece is quickly cut off by two sharp outer-edge blade points to obtain a required hole. The sheet drill can be used for drilling a sheet smoothly and cleanly and is safe and reliable. The sheet drill disclosed by the invention is simple in structure and convenient to manufacture; and polygon, hole port flash, great burr and the like can be avoided.
Description
Technical field
The present invention is a kind of drill bit, and a kind of specifically thin plate that bores sheet steel bores.
Background technology
On the thick sheet metal of 0.1～1.5mm, black sheet iron, thin aluminum sheet, sheet brass and sheet copper, hole; Can not use common drill bit; Otherwise the hole that gets out circle will occur, becomes polygonal, aperture overlap, burr are very big, even the thin plate torsional deformation, and the hole is torn.Big thin plate is difficult to be fixed on the lathe, if grasp thin plate boring, when the apex point with common fluted drill has just bored thoroughly; Drill bit loses the ability of centering, and workpiece is shaken, and blade is cut suddenly more; Penetrate thin plate, cutting force is anxious to be increased, and is prone to make drill bit to fracture 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 invention provides a kind of thin plate and bore with permanent magnet, it is neat and tidy, safe and reliable to bore thin plate with it.
In order to achieve the above object, the present invention realizes through following technical scheme:
The present invention 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 on the chip area of fluted drill, are crisscross arranged up and down fixedly install in each groove and the identical permanent magnet of each groove size.
Further improvement of the present invention is: apex point is higher than outer rim blade tip 1-1.5 millimeter.
The invention has the beneficial effects as follows: thin plate of the present invention bores, and apex point is cut workpiece earlier during brill, plays the centering effect; 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 is provided with on the drill bit adsorbs the chip that cuts; In order to avoid shelter from the workpiece that needs cutting, cause other accident.
The present invention is simple in structure, and is easy to make, phenomenons such as polygonal, aperture overlap, burr be very big can not occur.
Description of drawings
Fig. 1 is a structure chart of the present invention.
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 to understanding of the present invention, will combine accompanying drawing and embodiment that the present invention is described in further detail below, this embodiment only is used to explain the present invention, protection scope of the present invention is not constituted to limit.
Shown in Fig. 1; The present invention is that a kind of thin plate with permanent magnet bores; Comprise fluted drill 1, grind an apex point 2 on the top of said fluted drill 1, on said fluted drill 1, the left and right sides of said apex point 2 forms two outer rim swords 3; The top of said outer rim sword 3 is an outer rim blade tip 4, and said apex point 2 is higher than said outer rim blade tip 4 1-1.5 millimeters.Several grooves 5 that on the chip area of said fluted drill 1, are crisscross arranged up and down fixedly install in said each groove 5 and the identical permanent magnets 6 of said each groove 5 size.
Thin plate of the present invention bores, and apex point is cut workpiece earlier during brill, plays the centering effect, 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 is provided with on the drill bit adsorbs the chip that cuts, in order to avoid shelter from the workpiece that needs cutting, causes other accident.
The present invention is simple in structure, and is easy to make, phenomenons such as polygonal, aperture overlap, burr be very big can not occur.
Claims (2)
1. the thin plate with permanent magnet bores; Comprise fluted drill (1); It is characterized in that: grind an apex point (2) on the top of said fluted drill (1); The left and right sides last at said fluted drill (1), said apex point (2) forms two outer rim swords (3); The top of said outer rim sword (3) is outer rim blade tip (4), and several grooves (5) that on the chip area of said fluted drill (1), are crisscross arranged up and down fixedly install in said each groove (5) and the identical permanent magnet (6) of said each groove (5) size.
