The utility model content
The purpose of this utility model is to provide a kind of nut special molding cutter, greatly improves working (machining) efficiency, reduces 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, the acclivitous angle of described the 6th 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, in the second blade and the 3rd blade joint, with the arc surface transition, the radius of described arc surface is between 0.6-0.9mm.The setting of this structure, at formation obtuse angle, 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 the operating efficiency that rake face is removed 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.
The beneficial effects of the utility model: the utility model forming cutter 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, with the end face on the copper nut inwall, match, one-shot forming, this improves whole work working (machining) efficiency.
As from the foregoing, the utility model improves working (machining) efficiency greatly, reduces costs simultaneously.
In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.
