Description
Technical field
The present invention relates to a kind of nut special molding cutter.
Background technology
The copper nut of existing domestic refrigeration industry is ledrite and forges into blank, then machined, copper nut for 1/4 specification (small dimension) must add hacking hole operation one before machined, because blanking inner hole to the thickness of rear end face after, like this with regard to many procedures, manufacturing cost increases, and energy waste, have much room for improvement.
Addressing these problems is extremely urgent as from the foregoing!
In view of this, the inventor has done deep research, and by feat of the experience of being engaged in for many years relevant industries and practice, design a kind of nut special molding cutter, can solve deficiency of the prior art, greatly improve working (machining) efficiency, reduce costs simultaneously, this case produces thus.
Summary of the invention
The object of the present invention is to provide a kind of nut special molding cutter, greatly improve working (machining) efficiency, reduce costs simultaneously.
The nut special molding cutter, comprise handle of a knife, be provided with forming cutter on handle of a knife, it is characterized in that: described forming cutter comprises tool rest, form 2 symmetrically arranged inclination cambered surfaces on described tool rest, welding fabrication blade on tool rest, described shaping blades comprises that two lean against the edge structure that joins and arrange, described edge structure comprises blade group, rear knife face and rake face, described rear knife face and blade group are joined side by side, described rake face is arranged between the side of rear knife face side and blade group, with the inclination cambered surface, joins.
Further, described blade group comprises cutter hub, form inclined the first blade that dips down on the cutter hub top, with the first blade, join and be provided with rectilinear the second blade, connected downward-sloping formula the 3rd blade with the second blade, join and be provided with rectilinear four blade sword with the 3rd blade, with the four blade sword at right angles join be provided with run-in index the 5th blade, with the 5th blade connected the formula of being inclined upwardly the 6th blade.
Further, the angle angle between described 2 the 3rd blades is between the 89-93 degree.
Further, described the 6th acclivitous angle of blade is between the 35-40 degree.The setting of this structure, be beneficial to the arcwall face that forms the copper nut outer end edges, and precision is high, improves the quality of product.
Further, with the arc surface transition, the radius of described arc surface is between 0.6-0.9mm in the second blade and the 3rd blade joint.The setting of this structure, form obtuse angle at copper nut inwall place, avoid affecting product quality because of the generation of acute angle.
Further, described rake face is tilting arc knife face.The setting of this structure, in the copper nut process, improve rake face and remove the operating efficiency of unnecessary copper material.
Further, the angle angle between described 2 rake faces is between the 16-17 degree.
Further, described rear knife face comprises 3 blades that arrange continuously side by side with the first blade, the second blade, the 3rd blade.
Further, the outside end face of described rear knife face is inclined plane, and angle of inclination is the 14-16 degree.
Further, described rake face tilts to the inside, and its angle of inclination is the 9-11 degree.The setting of this angle, be beneficial to rake face in the copper nut manufacture process, the effect of performance rake face.
Beneficial effect of the present invention: forming cutter of the present invention has higher precision; add man-hour stressed evenly; while making processing 1/4 specification (small dimension) copper nut; without the hacking hole; a direct cutter moulding, so just reduced by a procedure, saved greatly cost; and saved the energy, preserve the ecological environment.
Wherein, the first blade, the second blade, the 3rd blade, four blade sword, the 5th blade, the 6th blade, rake face and rear knife face, in processing and manufacturing copper nut process, each blade or knife face form different effects, match with the end face on the copper nut inwall, one-shot forming, this improves whole work working (machining) efficiency.
As from the foregoing, the present invention improves working (machining) efficiency greatly, reduces costs simultaneously.
In order further to explain technical scheme of the present invention, the present invention will be described in detail below by specific embodiment.
