Abstract
The utility model belongs to the field of cutters, in particular to a four-blade molding knife which is used for processing a forming surface. The four-blade molding knife comprises a knife handle which is connected with a cutting power plant. A cutting part is connected with one end of the knife handle. The four-blade molding knife is characterized in that a circular arc transition section is arranged on the connecting area of the knife and the cutting part. The cutting part comprises an end face cutting blade and a side cutting blade. The end face cutting blade is arranged on the end face of the cutting part. The side cutting blade is arranged on the side edge of the cutting part. A first circular arc cutting blade is arranged between the end face cutting blade and the side cutting blade. A second circular arc cutting blade is arranged between the side cutting blade and the circular arc transition section. The four blades molding knife has the advantages that the molding knife can process irregularly shaped knives once according to the shape of the practical products, different knives do not need to be changed, and time is saved. Meanwhile, repeated positioning for products is not required, processing quality is guaranteed and processing accuracy is guaranteed.
Description
Technical field
The utility model belongs to the cutting tool field, particularly a kind of four sword forming cutters be used to being processed into profile.
Background technology
Development along with economic society, people are to the variation of the shape need of some daily necessitiess, also for a long time complex-shapedization of more present products, also machining is had higher requirement, some irregular shapes can't be processed with traditional cutter or be needed repeatedly tool changing and replacing locate mode just can finish processing, but so also have problems: because multiple bearing, certainly exist certain position error, even finished erose processing, its machining accuracy also can't meet the needs of production.
Summary of the invention
For the deficiencies in the prior art, the utility model is according to the shape of the product of reality, designed and a kind ofly can time processing go out erose forming cutter, need not to change different cutters, save process time, also need not product is carried out resetting simultaneously, guaranteed crudy and machining accuracy, and hardness and the heat-conductive characteristic of the PCD coating that arranges energy Effective Raise tool surface have prolonged cutting-tool's used life.
The utility model is achieved through the following technical solutions:
Four sword forming cutters, it comprises the handle of a knife that is connected with the cutting power set, one end of described handle of a knife is connected with cutting portion, it is characterized in that: the junction of described handle of a knife and cutting portion is provided with the arc transition section, described cutting portion comprises the face cutting edge that is arranged on the cutting portion end face and is arranged on the side cutting edge of cutting portion side, be provided with the first arc edge between face cutting edge and the side cutting edge, between side cutting edge and arc transition section, be provided with the second arc edge.
The surface of described cutting portion is coated with the PCD coating, and case hardness that can the Effective Raise cutter prolongs working durability of cutter, and the PCD coating has preferably heat-conductive characteristic simultaneously, has enough effectively will cut timely heat and distribute.
The cutting edge of described cutting portion arranges twist, and the chip removal performance of energy Effective Raise cutter is set twist.
Be provided with the less connecting rod of diameter between described handle of a knife and the cutting portion, the diameter of connecting rod is less, avoids in the process cutter to run into workpiece.
The junction of described handle of a knife and connecting rod is provided with taper seat.
In sum, the utlity model has following advantage: 1, can time processing mold needed shape, need not the repetition tool setting, shortened processing needed man-hour, improved crudy, 2, the PCD coating that arranges of tool surface, effectively raise the case hardness of cutter, prolonged cutting-tool's used life, blade adopts spirality to be provided with the chip removal ability that can be improved cutter simultaneously, also is conducive to prolong cutting-tool's used life.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged drawing at B place among Fig. 1;
1 is handle of a knife among the figure, and 2 is taper seat, and 3 is connecting rod, and 4 is the second arc edge, and 5 is the side cutting edge, and 6 is face cutting edge, and 7 is the first arc edge, and 8 is the arc transition section.
The specific embodiment
The utility model is achieved through the following technical solutions:
Four sword forming cutters as depicted in figs. 1 and 2, it comprises the handle of a knife 1 that is connected with the cutting power set, one end of described handle of a knife 1 is connected with cutting portion, it is characterized in that: described handle of a knife 1 is provided with arc transition section 8 with the junction of cutting portion, described cutting portion comprises the face cutting edge 6 that is arranged on the cutting portion end face and the side cutting edge 5 that is arranged on the cutting portion side, be provided with the first arc edge 7 between face cutting edge 6 and the side cutting edge 5, between side cutting edge 5 and arc transition section 8, be provided with the second arc edge 4.
The surface of described cutting portion is coated with the PCD coating, and case hardness that can the Effective Raise cutter prolongs working durability of cutter, and the PCD coating has preferably heat-conductive characteristic simultaneously, has enough effectively will cut timely heat and distribute.
The cutting edge of described cutting portion arranges twist, and the chip removal performance of energy Effective Raise cutter is set twist.
Be provided with the less connecting rod of diameter 3 between described handle of a knife 1 and the cutting portion, the diameter of connecting rod 3 is less, avoids in the process cutter to run into workpiece.
Described handle of a knife 1 is provided with taper seat 2 with the junction of connecting rod 3, and the taper seat of setting is further stepped down to workpiece, prevents that cutter from touching workpiece.
In sum, the utlity model has following advantage: 1, can time processing mold needed shape, need not the repetition tool setting, shortened processing needed man-hour, improved crudy, 2, the PCD coating that arranges of tool surface, effectively raise the case hardness of cutter, prolonged cutting-tool's used life, blade adopts spirality to be provided with the chip removal ability that can be improved cutter simultaneously, also is conducive to prolong cutting-tool's used life.
