Abstract
The utility model relates to a hollow drilling bit for soft materials. The hollow drilling bit comprises a drilling rod, a cutting edge arranged at one end of the drilling rod and a chip discharging through hole formed in the drilling rod, and the other end of the drilling rod is provided with a general clamping groove connected with equipment. When the hollow drilling bit is used, the drilling bit is installed on a machine frame, the materials which need to be drilled are placed at a preset position, the drilling rod rotates in the process that the drilling bit is pressed downwards, and therefore the cutting edge descends spirally in the drilling process. The abrasion intensity can be reduced compared with a punching tool, and the service life of the drilling bit can be prolonged. When the hollow drilling bit is used, a part of cut chips are discharged from the upper end of the drilling rod along the chip discharging through hole in the drilling rod, and use of the drilling bit cannot be affected even if the chips in a hollow cavity are not removed. Drilling of soft paper, soft plastic films and soft leather can be performed efficiently and rapidly.
Description
Technical field
The utility model relates to a kind of drill bit, relates in particular to a kind of hollow boring bit of soft material punching use.
Background technology
The cutter that is used for punching to paper, plastic sheeting, leather on existing market is that solid punch carries out punching mostly, and punching efficiency is low and not attractive in appearance.What have holes with fluted drill, and the pore area getting out has a lot of burrs very not attractive in appearance.Somely hole with core drill cutter, bore cutter and easily wear and tear, service life is short.These methods all can not be outstanding complete punching requirement.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of punching operating efficiency of soft material and hollow boring bit of product quality of improving.
The utility model adopts following technical scheme: a kind of soft material hollow boring bit, and comprise drilling rod, be arranged on the inside cutting edge of drilling rod one end cutting edge and be arranged on and go out to consider to be worth doing through hole in drilling rod, the drilling rod other end is provided with the general purpose card slot being connected with equipment.
Good effect of the present utility model is as follows: use when the utility model, drill bit is arranged in frame, the material of needs punching is put into predeterminated position, drill bit is pressing down drilling rod rotation in process, and cutting edge is spiral decline in punching process like this.The hole of accomplishing fluently so around can be not jagged, and for the instrument of dotting punch, wearing and tearing can reduce.Extend the service life of drill bit.The part chip cutting when use can be embedded in the hollow cavity of drilling rod, need not comprehend and continue to use chip to be discharged by drilling rod upper end along the through hole that goes out to consider to be worth doing of drilling rod, and the chip of not clearing up hollow cavity can not affect use yet.For soft paper, plastic sheeting, leather just punch can efficient quick operation.
Brief description of the drawings
Accompanying drawing 1 is the utility model structural representation;
Wherein: 1, drilling rod, 2, cutting edge, 3, go out to consider to be worth doing through hole, 4, general purpose card slot.
Detailed description of the invention
As shown in Figure 1, the soft material hollow boring bit of the utility model, comprises drilling rod 1, is arranged on the inside cutting edge 2 of drilling rod 1 one end cutting edge and is arranged on and go out to consider to be worth doing through hole 3 in drilling rod 1, and described drilling rod 1 other end is provided with the general purpose card slot 4 being connected with equipment.Use when the utility model, drill bit is arranged in frame, the material of needs punching is put into predeterminated position, drill bit is pressing down drilling rod 1 rotation in process, and cutting edge 2 is spiral decline in punching process like this.The hole of accomplishing fluently so around can be not jagged, can reduce than the tool wear intensity of dotting punch, can extend the service life of drill bit.The part chip cutting when use can be embedded in the hollow cavity of drilling rod 1, need not comprehend and continue to use chip to be discharged by drilling rod 1 upper end along the through hole 2 that goes out to consider to be worth doing of drilling rod 1, and the chip of not clearing up hollow cavity can not affect use yet.For soft paper, plastic sheeting, leather just punch can efficient quick operation.As shown in Figure 1, cutting edge 2 of the present utility model is circular, and cutting edge 2 of the present utility model can also be arc or sawtooth pattern.
