The forming tungsten steel tapping cutter is reasonable in structure and good in overall strength, the special-shaped boss can be machined at one step, one-step forming can be achieved, the machining process is simplified, efficiency is increased, and the smoothness of formed workpieces is guaranteed.
Description
Technical field
The present invention relates to hardware and cutting-tools technical field, particularly a kind of moulding wolfram steel is attacked cutter.
Background technology
Novel bearing product in recent years, in order to improve the performance of main frame, multi-band has the irregular flange disc that coordinates with main frame and other polymorphic structures, and wherein having a kind of polymorphic structure is with " boss " of one or two symmetry on a side end face of bearing ring.The at present common general mode that adopts grinding of different in nature boss processing, adopts emery wheel to be polished in each side of boss respectively, and this processing mode is batch (-type) processing, has extended the activity duration, has reduced operating efficiency.And after polishing, the crossover position between each side can produce burr, has increased operating personnel's workload, has reduced production efficiency.
Summary of the invention
The object of the invention is to defect and deficiency for prior art, provide a kind of moulding wolfram steel rational in infrastructure, easy to use to attack cutter, for the processing of different in nature boss.
For achieving the above object, the present invention is by the following technical solutions:
A kind of moulding wolfram steel of the present invention is attacked cutter, comprises the handle of a knife and the cutter head that are wholely set, wherein, the end surface side of described cutter head is along having a flange, the middle part of end face is the boss of a circle shape, and described flange, higher than described boss, is blade between described flange and described boss; Described blade comprises the first blade, the second blade and the 3rd blade connecting successively, and described the first blade is connected with described boss, and described the 3rd blade is connected with described flange; Between described the first blade and Y-axis, be 20 degree angle settings, be 60 degree angle settings between described the 3rd blade and Y-axis, described the second blade is that Radius is the arc surface of 3mm; On described cutter head, be also provided with a circular-arc chip area, described circular-arc chip area is connected to the bottom of described cutter head from described boss center; Two orthogonal linear pattern grooves are also set on described boss, and its intersection point is positioned at the center of described boss, and described linear pattern groove is communicated to described chip area.
Further, the radius of described circular-arc chip area is 28mm.
Further, the width of described linear pattern groove is 2mm, and the degree of depth is 2mm.
Further, the diameter of described cutter head is 26mm, and the diameter of described boss is 14mm.
Further, described flange is than the high 5mm of described boss.
Beneficial effect of the present invention is: moulding wolfram steel provided by the invention attacks that knife structure is reasonable, and cutter bulk strength is better, for different in nature boss, processes at one time, can one-shot forming, simplify work flow, and raise the efficiency, and guaranteed the fineness of shaping workpiece.
Accompanying drawing explanation
Fig. 1 is the front view that moulding wolfram steel provided by the invention is attacked cutter;
Fig. 2 is the upward view that moulding wolfram steel provided by the invention is attacked cutter;
Fig. 3 is as the inversion enlarged diagram of the A portion in Fig. 1.
In figure: 1, handle of a knife; 2, cutter head; 201, flange; 202, boss; 203, blade; 2031, the second blade; 2032, the first blade; 2033, the 3rd blade; 204, groove; 205, chip area.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Consult Fig. 1-3, a kind of moulding wolfram steel provided by the invention is attacked cutter, comprise the handle of a knife 1 and the cutter head 2 that are wholely set, wherein, the end surface side of described cutter head 2 is along having a flange 201, the middle part of end face is the boss 202 of a circle shape, and described flange 201, higher than described boss 202, is blade 203 between described flange 201 and described boss 202; On described cutter head 2, be also provided with a circular-arc chip area 205, described circular-arc chip area 205 is connected to the bottom of described cutter head 2 from described boss 202 centers.As shown in Figure 3, described blade 203 comprises the first blade 2032, the second blade 2031 and the 3rd blade 2033 connecting successively, and described the first blade 2032 is connected with described boss 202, and described the 3rd blade 2033 is connected with described flange 201; Angle α 1 between described the first blade 2032 and Y-axis is 20 degree, and the angle α 2 between between described the 3rd blade 2033 and Y-axis is 60 degree, and described the second blade 2031 is an arc surface, and its radius R 1 is 3mm; Two orthogonal linear pattern grooves 204 are also set on described boss 202, and its intersection point is positioned at described boss 202 center, and described linear pattern groove 204 is communicated to described chip area 205.Groove is set on boss, makes to add the scrap producing man-hour and better discharge, in the present embodiment, the width of described linear pattern groove 204 is 2mm, and the degree of depth is 2mm.
