Abstract
The utility model disclose a three-knife-edge cutting knife which comprises a bracket, disc cutting knifes and a handle, wherein the front end of the bracket is provided with one disc cutting knife by a pin shaft; the rear end of the bracket is provided with a nut sleeve which is internally provided with a screw rod; the rear end of the screw rod is provided with the handle; the front end of the screw rod is connected with a knife rest, one end of which is installed on a bracket slideway in a sliding way; and the knife rest is provided with the other two disc cutting knifes by pin shafts. The three-knife-edge cutting knife is simple in structure, small in volume and light in weight, and can be used in a narrow space. The three disc cutting knives simultaneously work on a radial cutting plane, and a metal pipe can be cut off with a rotation angle less than 180 degrees. The processed pipe orifice has no burr, and is not deformed and contracted.
Description
Technical field
The utility model relates to a kind of tubing cutting tool, is specifically related to a kind of three sword cutteves of incising pipes.
Background technology
At present, hobboing cutter cutting metal tubing has advantages such as efficient height, no chip, otch be smooth, is widely used in production, processing and the use of metal pipe material.Yet, the hobboing cutter cutting tool of prior art or equipment generally all exist complex structure, volume big, use shortcoming such as inconvenience.As: in the up casting method of copper pipe, on draw that copper pipe is continual draws, when being drawn out to the charge length of regulation, need cut off the processing of carrying out next step.Need draw a plurality of copper pipes simultaneously because of every stove of up casting method, after copper pipe is drawn, arrange the copper pipe gap side by side seldom, utilize large-scale cutting machine inconvenience can not use common parting tool to carry out 360 ° revolution cutting.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of three sword cutteves of simple in structure, suitable crawl space incising pipes are provided.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of three sword cutteves, it comprises support, wheel cutter, handle, it is characterized in that: the front end at support is installed a wheel cutter by bearing pin, there is ut socket rear end at support, and screw rod is installed on ut socket, and the rear end of screw rod is a handle, the front end of screw rod connects an end and is slidably mounted on a knife rest on the support slideway, by bearing pin two wheel cutters is installed on the knife rest.
The bearing pin of described installation wheel cutter is installed on support and the knife rest by axle sleeve or bearing.
The utility model compared with prior art has following advantage: it mainly is made up of support, knife rest, three wheel cutters, screw rod and handles, simple in structure, volume is little, in light weight, can use at small space.By the operation simultaneously of three wheel cutters, its anglec of rotation is no more than 180 ° just can cut off metal tube, has improved cutting speed on a radial cuts plane.Be connected with screw tip when described knife rest is slidably mounted on the slideway of support one side, the blade that has guaranteed three wheel cutters in one plane.The pipe fitting that cutting obtains through the utility model, its mouth of pipe do not have burr, do not have distortion, do not have and shrink, thereby have improved the working (machining) efficiency of whole pipe fitting.
Description of drawings
Fig. 1 is the copper pipe perspective view of the utility model three sword cutteves and clamping;
Fig. 2 is the utility model three sword cutter perspective view;
Fig. 3 is the copper pipe side structure schematic diagram of three sword cutteves of the present utility model and clamping;
Among the figure: 1. handle, 2. screw rod, 3. ut socket, 4. support, 5. knife rest, 6. slideway, 7. wheel cutter, 8. wheel cutter, 9. wheel cutter, 10. copper pipe.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further.
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of three sword cutteves, it comprises support 4, wheel cutter 7,8,9 and handle 1; Front end at support 4 is installed a wheel cutter 9 by axle sleeve and bearing pin, in the rear end of support 4 ut socket 3 is arranged, screw rod 2 is installed on ut socket 3, the rear end of screw rod 2 is handles 1, the front end of screw rod 2 connects an end and is slidably mounted on a knife rest 5 on the support slideway 6, by axle sleeve and bearing pin two wheel cutters 7,8 is installed on the knife rest 5.In use, at first, copper pipe 10 put between the wheel cutter 7,8,9 and fixing, want before putting into by screw rod wheel cutter 7,8 is transferred to the extreme higher position earlier, copper pipe 10 is put into, and rotation adjusting screw(rod) 2 makes wheel cutter 7,8,9 contact copper pipe 10 simultaneously to have reached fixedly purpose.Then, after copper pipe 10 fixed, hold handle 1 and make wheel cutter 7,8,9 along doing circumference rotation cutting on the copper pipe diametric(al).
Claims (2)
