Abstract
The utility model relates to the technical field of tools, in particular to a novel combined type external cutter tool and blade. The novel combined type external cutter tool comprises a combined type tool apron, and the carbide blade is installed on the combined type tool apron and pressed between the combined type tool apron and a compressing sleeve. The novel combined type external cutter tool and blade are characterized in that the carbide blade comprises two asymmetrical tool faces, the angle of one tool face of the carbide blade ranges from 0 degree to 15 degrees, the angle of the other tool face ranges from 10 degrees to 50 degrees, and the angles of the tool faces are the included angles between the tool faces and the vertical face where a point is located. By the adoption of the technical scheme, compared with the prior art, the novel combined type external cutter tool and blade have the following advantages that after the asymmetrical tool face structure is adopted, the problems that in the prior art, the left end of a closed opening of an orifice of the cut surface of a copper pipe is large and the right end is small can be effectively solved, the problems of the closed opening of the orifice of the cut surface of the right end is obviously solved, the quality of the cut surface of the copper pipe is improved, the closed opening of the orifice of the cut surface is further reduced, the service life of the tool is prolonged, production efficiency is improved, and tool procurement cost of air conditioner manufacturers is reduced.
Description
Technical field
The utility model relates to cutting-tool engineering field, relates in particular to a kind of novel combination type outer cut cutter and blade.
Background technology
On the basis of the utility model patent " a kind of novel combination type outer cut cutter " (patent No. ZL201220019059.1) of this combined type cutoff tool Shi Wo company application on January 16th, 2012, the better chipless outer cut of a result of use of exploitation.
This blade is arranged on above alignment cutting machine, utilize cutting edge rolling cut tubing, in the time of rolling cut, copper pipe two ends are in tension, near copper pipe one end of outer cut in fixing to clamp state, away from one end of copper pipe in clamping and tension, there is certain pretension, this pretension, in copper pipe cut-out work, can extend distortion along cutting port plasticity, and when copper pipe will cut off, breaks copper pipe and move to certain place.
Former combined type cutoff tool is double-edged blade, the angle of blade is symmetrical, there will be in the course of the work near one end of outer cut and think and maintain static, so the reducing of section is larger than cutting off aperture, one end reducing of pulling open, this problem is also the ubiquitous problem of common outer cut of current domestic production.Particularly, for heavy wall copper pipe, this phenomenon is more obvious.
Summary of the invention
utility model content
The object of utility model: for a kind of novel combination type outer cut cutter is provided, it has solved reducing problem when copper pipe cuts off better, has improved the quality of tubing section.
In order to reach as above object, the utility model is taked following technical scheme:
Scheme 1:
A kind of novel combination type outer cut cutter, comprise Combined knife base, carbide chip is installed on Combined knife base, described carbide chip is pressed between Combined knife base and clamping sleeve, it is characterized in that, described carbide chip comprises two asymmetric knife faces.
The further technical scheme of the utility model is, carbide chip, Combined knife base, clamping sleeve three welding.
The further technical scheme of the utility model is, described carbide chip is removably fixed between Combined knife base and clamping sleeve.
The further technical scheme of the utility model is, the endoporus of described carbide chip is of a size of, and outside dimension is that gauge is 0.3---11.0 mm.
The further technical scheme of the utility model is, described carbide chip is knife face angle--15 °, another side knife face angle is 10 °---50 ° that be 0 ° on one side, and described knife face angle is the angle between knife face and the vertical plane at blade tip place.
The further technical scheme of the utility model is, 20 ° of the blade angles of described carbide chip---50 °.
Scheme 2:
A kind of asymmetric blade, it is characterized in that, comprise carbide chip (2), it comprises two asymmetric knife faces, carbide chip (2) on one side knife face angle is 0 °--15 °, another side knife face angle is 10 °---50 °, described knife face angle is the angle between knife face and the vertical plane at blade tip place.
Adopt as above the utility model of technical scheme, with respect to prior art, there is following beneficial effect: adopt after asymmetrical knife face structure, discovery can effectively solve current otch left end greatly and the little problem of right-hand member, find significantly to have reduced the reducing in right-hand member section aperture, the reducing of aperture, two ends is evenly neat, the utility model adopts hardness very high, the difficult-to-machine material that wearability is very strong--carbide alloy is as cutting edge roundness, it can extend the service life of cutter greatly, again because fine finishining again after welding together, so guaranteed again the overall precision of cutter, it has reduced the frequent cutter of changing in the former equipment course of work, the time of frequently shunting, improved production efficiency, reduced the purchase cost of air-conditioning producer cutter.He Yuanwo company combined type patent blade is compared, and has further improved the quality stability of tubing section reducing.
accompanying drawing explanation
In order to further illustrate the utility model, below in conjunction with accompanying drawing, further describe:
Fig. 1 is the structural representation of utility model;
Wherein: 1. Combined knife base, 2. carbide chip; 3. clamping sleeve.
the specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, embodiment does not form restriction of the present utility model:
Scheme 1:
A kind of novel combination type outer cut cutter, comprise Combined knife base 1, carbide chip 2 is installed on Combined knife base 1, described carbide chip 2 is pressed between Combined knife base 1 and clamping sleeve 3, it is characterized in that, described carbide chip 2 comprises two asymmetric knife faces.Carbide chip 2, Combined knife base 1, clamping sleeve 3 three's welding.Described carbide chip 2 is removably fixed between Combined knife base 1 and clamping sleeve 3.The endoporus of described carbide chip 2 is of a size of, and outside dimension is that gauge is 0.3---11.0 mm.
Clearly, carbide chip 2 can be dismantled and also can make integrated welding connect thereon, but if be removably fixed with, can in stability and removable angle, find an equalization point, being removably fixed with of this place can make carbide chip 2 bottoms have fixing hole, by Luoding or pin, blade fixed.Described carbide chip 2 is knife face angles--15 °, another side knife face angle is 10 °---50 ° that be 0 ° on one side, and described knife face angle is the angle between knife face and the vertical plane at blade tip place.
