Abstract
The utility model provides a novel boring-machine drill-bit. The utility model is characterized in that the boring-machine drill-bit is cylindrical. The cutting edge of the boring-machine drill-bit is a 360 DEG continuous-circumference cutting edge. The cylinder is provided with a push rod inside. The cylinder face of the boring-machine drill-bit is provided with a getter groove. A rotary-cutting boring machine which is provided with the boring-machine drill-bit has beautiful appearance. Holes which are drilled by the utility model are smooth, clean and regular. The drill bit does not need sharpening, and can be widely used for the binding work and the boring work of papers and bills in the departments of institutions, schools, banks, etc.
Description
The utility model relates to a kind of puncher drill bit and puncher.
According to the knowledge of the applicant, existing puncher drill bit all is solid drill bit, and the cutting edge of drill bit is discontinuous cutting edge, and there is following deficiency in the drill bit of this structure: the hole of 1, getting is not bright and clean, regular; 2, paper-pressing mechanism to be arranged; 3, drill bit often needs sharpening; 4, it is not very convenient thinning paper and ground paper.
The purpose of this utility model is intended to overcome above-mentioned the deficiencies in the prior art, proposes a kind of novel holing machine drill head and puncher.
Realize the technical scheme of above-mentioned purpose: a kind of novel holing machine drill head, its drill bit is cylindric, the cutting edge of drill bit is the contiguous circumferential cutting edge of 360 degree.
Dress push rod in the puncher drill bit cylindraceous.
Have the groove of cooling down on the cylinder of puncher drill bit.
A kind of rotary-cut puncher mainly is made up of screw-down, frame and the puncher drill bit cylindraceous of motor-operated main shaft, tool handle.The cutting edge of cylindric drill bit is the contiguous circumferential cutting edge of 360 degree, dress push rod in the drill bit, and drill bit connects with axle sleeve by coupling sleeve, and axle sleeve and main shaft are fixedly connected.
The spring of screw-down is a stage clip.
Puncher drill bit and rotary-cut puncher according to the such scheme making, because the cutting edge of drill bit is the contiguous circumferential cutting edge of 360 degree, tool cavity in the cutting edge, paper scrap under the rotary-cut enters the cutting edge inner chamber, beaten when drill bit is mentioned behind the hole, automatically discharge, thereby the hole of getting is inevitable bright and clean, regular, is not subjected to the influence of the thick a surname of paper; In addition, because the punching section of drill bit is extremely broad cylinder, drill bit does not need sharpening, and this device does not need paper-pressing mechanism yet, thereby has realized the purpose of this utility model.
Further specify below in conjunction with accompanying drawing:
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is an another kind of structural representation of the present utility model.
Fig. 3 is a kind of rotary-cut puncher.
Fig. 4 is that the A-A of Fig. 3 is to cutaway view.
Embodiment one: with reference to Fig. 1, and a kind of novel holing machine drill head, drill bit 1 is cylindric, and the cutting edge 2 of drill bit 1 is the contiguous circumferential cutting edge of 360 degree, and the thickness of smear metal cutting edge 2 is the front end thickness cylindraceous of drill bit 1.
Embodiment two: with reference to Fig. 2, and another kind of novel holing machine drill head, drill bit 1 is cylindric, has the groove 3 of cooling down on the drill bit 1, and the cutting edge 2 of drill bit 1 is the contiguous circumferential cutting edge of 360 degree, and the thickness of smear metal cutting edge 2 is the front end thickness cylindraceous of drill bit 1.
Embodiment three: with reference to Fig. 3 and Fig. 4, a kind of rotary-cut puncher mainly is made up of drill bit 1 cylindraceous, motor 19, main shaft 9, axle sleeve 6, coupling sleeve 32, screw-down, frame 16 and base 29.The cutting edge 2 of cylindric drill bit 1 is the contiguous circumferential cutting edge of 360 degree, dress push rod 31 in the drill bit 1, drill bit 1 connects with axle sleeve 6 by coupling sleeve 32, sleeve 8 is arranged on the axle sleeve 6, axle sleeve 6 is by bearing (5,10) connect with main shaft 9, motor 19 is through belt pulley (11,20), belt 21 drives main shaft 9 and rotates, motor 19 is fixed on the frame 16 by screw 18, frame 16 is supported by base 29 by trip bolt 15, there are sheath 4 usefulness screws 30 fastening on the coupling sleeve 32, have sliding tray on the axle sleeve 6, sliding pin 7 is arranged in the groove, screw-down is by handle 22, fork 23, stage clip 25 constitutes with the pin 24 that links to each other with sleeve 8, and drawer 28 is arranged on the base 29.
The course of work of rotary-cut puncher: the power supply of connecting motor, drill bit 1 begins rotation, to go handle 22 to pressing down, drive fork 23 and sleeve 8 is moved downward, realize rotary-cut by pin 24, the paper scrap that cuts out is dissolved in drill bit 1 inner chamber, after paper drills through, will lift on the handle 22, because the active force of spring 25, by push rod 31 paper scrap is discharged, punching is finished.
The drill bit of rotary-cut puncher is replaceable, and the clamping distance can be adjusted, and the solid screw 27 that fixedly is close to of drill bit 1 is finished, and after drill bit 1 installed, stroke was adjusted with stop screw 26.
In embodiment three, have the groove better effects if of cooling down on the cylinder cylinder of puncher drill bit 1.
Can cancel push rod 31 in the drill bit 1.
Above-mentioned rotary-cut puncher good looking appearance can be widely used in the paper in the departments such as office, school, bank, the bookbinding punching work of bill.
