Ripple torticollis one-shot forming cutter
Technical field
The invention belongs to tool for cutting machining technical field, relate to the dedicated tool of booster mouth of pipe processing, be specially a kind of ripple torticollis one-shot forming cutter.
Background technology
The processing of aluminium alloy booster Cyrtophorina, usually many handles (more than two) lathe tool to be adopted to process according to the concrete shape of mouth of pipe different parts, adopt many purchase costs lathe tool just being added cutter, add and connect cutter number of times, easy generation connects tool marks, the size Control difficulty connecing cutter position is comparatively large, and the risk that therefore quality problems occur is just higher, and in processing, constantly tool changing causes again complicated operation and waste of time simultaneously.
At present in order to solve the problem, general way is the professional skill of the personnel of developing skill, amendment technological parameter etc.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of structure simple, ingenious, rational ripple torticollis one-shot forming cutter is provided, can solve booster mouth of pipe processing in prior art needs many lathe tool, cutter purchase cost is high, and the problem connecing tool marks easily produced in the processing of much knives tool.
According to technical scheme provided by the invention: a kind of ripple torticollis one-shot forming cutter, comprise cylindrical handle of a knife and be arranged at the cutter head of handle of a knife end, blade is welded on cutter head, it is characterized in that: described blade has four, and, four blades are distributed on cutter head outer circumference surface, the front end of described blade has end cutting edge, rear end and extend to fore-end from rear end there is main cutting edge, chip pocket is provided with between adjacent two main cutting edges, described main cutting edge comprises the first main cutting edge being arranged at blade straight operative tip and the second main cutting edge being arranged at blade rear end.
As a further improvement on the present invention, bottom described chip pocket be arc-shaped.
As a further improvement on the present invention, the second main cutting edge of blade rear end is gradient shape, and the second main cutting edge rear height is greater than front height.
As a further improvement on the present invention, the first main cutting edge is the corrugated of uniformly continous, and for arc transition is connected between the first main cutting edge with end cutting edge, further, the radius of the circular arc of transition junction is 0.2mm ± 0.01mm.
As a further improvement on the present invention, the angle of cutting edge of the described end and cutter head radial direction is 2 ° ± 0.05 °.
The present invention compared with prior art, advantage is: structure of the present invention is simple, ingenious, reasonable, can solve booster mouth of pipe processing in prior art needs many lathe tool, cutter purchase cost is high, and easily produce in the processing of much knives tool connect the problems such as tool marks, the present invention is not simultaneously owing to needing to carry out tool changing, and working (machining) efficiency is high, and cutter life of the present invention is long.

Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Fig. 1 ~ 3, bottom end cutting edge 1, cutter head 2, blade 3, main cutting edge 4, first main cutting edge 4-1, the second main cutting edge 4-2, handle of a knife 5, chip pocket 6, chip pocket 7 etc.
As shown in Figure 1, the present invention is a kind of ripple torticollis one-shot forming cutter, comprise cylindrical handle of a knife 5 and be arranged at the cutter head 2 of handle of a knife 5 end, blade 3 is welded on cutter head 2, described blade 3 has four, and, four blades 3 are distributed on cutter head 2 outer circumference surface, the front end of described blade 3 has end cutting edge 1, rear end and extend to fore-end from rear end there is main cutting edge 4, chip pocket 7 is provided with between adjacent two main cutting edges 4, described main cutting edge 4 comprises the first main cutting edge 4-1 being arranged at blade 3 straight portion top and the second main cutting edge 4-2 being arranged at blade 3 rear end.
Bottom described chip pocket, 6 in arc-shaped.
Second main cutting edge 4-2 of blade 3 rear end is gradient shape, and the second main cutting edge 4-2 rear height is greater than front height, in process of manufacture, and the second main cutting edge 4-2 machinable booster mouth of pipe endoporus.
First main cutting edge 4-1 is the corrugated of uniformly continous, and the first main cutting edge 4-1 with between end cutting edge 1 for arc transition is connected, further, the radius of the circular arc of transition junction is 0.2mm ± 0.01mm.
Cutting edge of the described end 1 is 2 ° ± 0.05 ° with the angle of cutter head 2 radial direction.
The material of cutter head 2 and handle of a knife 5 is high-speed steel, and blade 3 is made up of polycrystalline diamond material, make lathe tool rigidity of the present invention comparatively and uniformity better, cutter life is long.
Structure of the present invention is simple, ingenious, reasonable, can to solve in prior art the processing of the booster mouth of pipe needs many lathe tool, and cutter purchase cost is high, and in the processing of much knives tool easily generation connect the problems such as tool marks, the present invention is not simultaneously owing to needing to carry out tool changing, and working (machining) efficiency is high.
