Abstract
The utility model relates to a cutting tool, in particular to a novel metal cutting piece which is suitable for cutting metal pipe fittings and so on. The metal cutting piece takes the shape of a round disc, an electromotor fixing hole (1) is arranged at the middle part of the metal cutting piece, and a slit (2) is arranged at the margin of the round-disc metal cutting piece. The material of the metal cutting piece is of metal. The metal cutting piece of the utility model has long service life which is more than three times longer than the service life of a sand-disc cutting piece and a serrated metal cutting piece that are used at present.
Description
Technical field
The utility model relates to cutting tool, is specially a kind of novel metal cutting blade, is applicable to cutting metal pipe fitting etc.
Background technology
Present metal tube cutting blade is divided into two kinds, the one, emery disc form cutting blade, it is characterized in that this cutting blade material is an emery wheel, rotate at a high speed and be cut fitting to fitting and acutely rub by driven by motor emery disc form cutting blade, metal tube and emery disc form cutting blade are in friction, a large amount of wearing and tearing all appear in both contact-making surfaces, thereby realize the disconnected tube wall that cuts metal tube, its friction cuttings principle is that sand grains hardness in the emery disc form cutting blade is greater than being cut metal, but between the sand grains at the bottom of the bonding precision, such product shortcoming just is the high wear rate of cutting blade, the cutting blade replacement cycle is short, if the construction cost height is more low at higher its cutting efficiency of metal tube of hardness ratio.Its material of another cutting blade is a metal, the edge of cutting blade is sawtooth pattern, rotate at a high speed and be cut pipe fitting by driven by motor sawtooth pattern cutting blade firmly to hard cutting, sawtooth quick wearing and tearing passivation in cutting process need be polished one by one to sawtooth and be kept sharp, the cutting blade loss is rapid, the process of sawtooth polishing extremely bothers, the polishing of sawtooth also makes cutting operation efficient reduce, section after the cutting blade cutting of this spline structure is uneven, also very difficult in the cutting operation to being cut fixing of pipe fitting, occur being cut the situation that pipe fitting is beated easily, the cutting blade edge weares and teares by a small margin also can cause the reduction of cutting efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, long service life, novel metal cutting blade that cutting efficiency is high at above technical problem.
Concrete technical scheme of the present utility model is as follows:
The Metal Cutting sheet is a disc, and the middle part is provided with motor shaft fixing hole (1), and the edge of disc Metal Cutting sheet is provided with bar seam (2).
Described Metal Cutting sheet material is a metal.
Disc Metal Cutting sheet is fixed on the motor shaft by motor shaft fixing hole (1), electric motor starting cuts metal tube later, the edge of disc Metal Cutting sheet and the position that is cut of metal tube acutely rub, be cut the position and in friction, can produce a large amount of heat, and this heat concentrates on and can not in time leave in the very little scope of cutting part, be cut metal its material deliquescing or thawing after temperature rises of metal tube, and that the friction position of the utility model cutting blade is the comprehensive contact area in edge of whole disc Metal Cutting sheet is big, temperature on the unit are is low, the position that just participates in friction in the cutting blade rotary course will be left friction and be cut the position and be in the air and suitably lower the temperature, the temperature at cutting blade edge is well below the temperature of the cutting part that is cut metal tube on the whole, its hardness can be affected hardly, this moment, the hardness of cutting blade was far longer than the hardness that is cut metal tube friction position, the part that is cut metal tube that bar seam (2) structure of disc Metal Cutting sheet edge setting simultaneously will be softened scrapes, thereby realizes being cut the cutting operation of pipe fitting.
Good effect of the present utility model shows:
1, the utility model Metal Cutting sheet long service life is emery disc form cutting blade, more than three times of sawtooth Metal Cutting sheet that use at present.
2 the utility model Metal Cutting sheet cutting efficiency height, to the metal tube that is cut of same specification, the utility model Metal Cutting sheet has only 2/3rds of present emery disc form cutting blade, sawtooth Metal Cutting sheet required clipping time.
3 can reduce the construction operation cost significantly by implementing the utility model, and the replacing amount still less in the cutting blade fundamental operation amount.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Wherein, 1---motor shaft fixing hole, 2---bar seam.
The specific embodiment
The utility model is described in further detail below in conjunction with the specific embodiment and accompanying drawing.
The Metal Cutting sheet is a disc, and the middle part is provided with motor shaft fixing hole (1), and the edge of disc Metal Cutting sheet is provided with bar seam (2).
Described Metal Cutting sheet material is a metal.
Disc Metal Cutting sheet is fixed on the motor shaft by motor shaft fixing hole (1), electric motor starting cuts metal tube later, the edge of disc Metal Cutting sheet and the position that is cut of metal tube acutely rub, be cut the position and in friction, can produce a large amount of heat, and this heat concentrates on and can not in time leave in the very little scope of cutting part, be cut metal its material deliquescing or thawing after temperature rises of metal tube, and that the friction position of the utility model cutting blade is the comprehensive contact area in edge of whole disc Metal Cutting sheet is big, temperature on the unit are is low, the position that just participates in friction in the cutting blade rotary course will be left friction and be cut the position and be in the air and suitably lower the temperature, the temperature at cutting blade edge is well below the temperature of the cutting part that is cut metal tube on the whole, its hardness can be affected hardly, this moment, the hardness of cutting blade was far longer than the hardness that is cut metal tube friction position, the part that is cut metal tube that bar seam (2) structure of disc Metal Cutting sheet edge setting simultaneously will be softened scrapes, thereby realizes being cut the cutting operation of pipe fitting.
Claims (2)
1, Metal Cutting sheet is characterized in that: the Metal Cutting sheet is a disc, and the middle part is provided with motor shaft fixing hole (1), and the edge of disc Metal Cutting sheet is provided with bar seam (2).
2, Metal Cutting sheet according to claim 1 is characterized in that: described Metal Cutting sheet material is a metal.
