In comparison with the prior art, the large multi-angle flat-end chamfering machine tool in the utility model has the beneficial effects that the blade is provided with multiple angles on the flat-end chamfering machine, a crevasse has a high-quality surface after processing; the tool is replaced and adjusted conveniently and rapidly, a machine is operated stably, production efficiency is high and a requirement for multi-angle chamfering of a steel pipe with a big wall thickness of more than 22 mm is satisfied; and design is reasonable, the tool is simple and practical, operation is safe and use is convenient.

Description

The large-scale flat head chamfering rounding machine cutter of multi-angle
Technical field
The utility model belongs to Steel pipe end surface process equipment, relates in particular to End-facing/chamfering Machine For Steel Tubes cutter, is specially adapted to the cutter of large wall thickness steel tube plain-end chamfering machine.
Background technology
In prior art, Steel Tube Industry mostly carries out flat head chamfering to pipe end, and the bevel angle of chamfered edge is generally 30.5 °, 37.5 °, 45 etc.The cutter of existing plain-end chamfering machine is single bevel angle, and the deficiency of existing plain-end chamfering machine is:
1, single bevel angle, cutting power is large; The metal that need to fill during butt welding between steel pipe increases, and production efficiency is low;
If 2 adopt lathe processing multi-angle groove, production efficiency is extremely low;
If 3 adopt gang tool processing multi-angle groove on plain-end chamfering machine, groove face poor quality, can not meet the demands, and cutter is adjusted complicated.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of multi-angle large-scale flat head chamfering rounding machine cutter, completes flat head chamfering and the beveling of pipe end on large-scale plain-end chamfering machine.
The purpose of this utility model is to adopt following technical scheme to realize: the large-scale flat head chamfering rounding machine cutter of multi-angle, comprise cutterhead, on cutterhead, be symmetrically installed with planar end surface cutter and interior rose reamer, it is characterized in that the large-scale flat head chamfering rounding machine cutter of described multi-angle also comprises multi-angle cutter, one-to-many angular cutter symmetry is arranged on cutterhead, described multi-angle cutter is by knife bar, blade, pad, pressing plate and bridge screw form, knife bar is arranged on cutterhead, pad is installed in the groove of knife bar front end from the inside to the outside successively, blade and pressing plate, pressing plate front end is pressed in blade face, rear end is fixed on knife bar by bridge screw.
The large-scale flat head chamfering rounding machine cutter of multi-angle described in the utility model, the anterior angle α that it is characterized in that described blade is 8 °; Relief angle β is 7 °; Cutting edge inclination θ is 4 °, and the cutting edge angle γ of blade need to select according to user.
The large-scale flat head chamfering rounding machine cutter of multi-angle described in the utility model, the length L=70mm of the blade described in it is characterized in that, blade is rhombus.
The course of work of the present utility model is as follows:
At least a set of multi-angle cutter of installing, a set of planar end surface cutter, a set of interior rose reamer on the cutterhead of plain-end chamfering machine, adjust tool position, set feed speed, cutting speed, then cutterhead swivel feeding cuts fixed pipe end, complete after cutwork, cutterhead is return original position.
Compared with prior art the beneficial effects of the utility model are: on plain-end chamfering machine, realized a blade and had a plurality of angles, after processing, groove face quality is good; Cutter changing and quick, machine easy to adjust operate steadily, and production efficiency is high, meets the multi-angle chamfered edge requirement that wall thickness is greater than 22mm large wall thickness steel tube; Reasonable in design, simple and practical, handling safety, easy to use.
Accompanying drawing explanation
The utility model has four width accompanying drawings.Wherein:
Accompanying drawing 1 is main TV structure schematic diagram of the present utility model;
Accompanying drawing 2 is that Fig. 1 is along A place enlarged diagram;
Accompanying drawing 3 is that the K of Fig. 2 is to view;
Accompanying drawing 4 is B-B cutaway views of Fig. 3;
In figure: 1, planar end surface cutter, 2, cutterhead, 3, knife bar, 4, interior rose reamer, 5, pad, 6, blade, 7, pressing plate, 8, bridge screw, 9, steel pipe.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment is for to external diameter Ф 323.9 ~ Ф 720mm, and the pipe end of wall thickness 22 ~ 50mm carries out the large-scale flat head chamfering rounding machine cutter of a kind of multi-angle of multi-angle processing.The symmetrical multi-angle cutter of installing on plain-end chamfering machine cutterhead 2, each multi-angle cutter is comprised of knife bar 3, blade 6, pad 5, pressing plate 7, bridge screw 8.Knife bar 3 is arranged on cutterhead 2, and pad 5, blade 6, pressing plate 7 are installed successively from the inside to the outside in the groove of knife bar 3 front ends, and pressing plate 7 front ends are pressed in blade 6 surfaces, and its rear end is fixed on knife bar 3 by bridge screw 8.The anterior angle α of blade 6 is 8 °; Relief angle β is 7 °; Cutting edge inclination θ is 4 °, and the size of the cutting edge angle γ of blade 6 is need to select according to user.Length L=the 70mm of blade 6, blade 6 adopts rhombus.
The above; it is only the preferably specific embodiment of the present utility model; but protection domain of the present utility model is not limited to this; allly be familiar with those skilled in the art in the disclosed technical scope of the utility model, within being equal to and replacing or change and all should be encompassed in protection domain of the present utility model according to the technical solution of the utility model and design of the present utility model thereof.
