Abstract
The utility model discloses a novel carbide double -end path boring cutter, including the cutter, the cutter includes cutter arbor, tool bit structure, the tool bit structure is two, the cutter arbor is including the cylindric body of rod that is located the middle part, a tool bit structure is connected respectively at the both ends of the cylindric body of rod, the cylindric body of rod with be connected the sword handle structure of tool bit structure composing who serves at one of them, this sword handle structure with be connected the tool bit structure composing cutter on the cylindric body of rod other end. The utility model has the advantages of adopted distinctive two -sided location, the high location of tool changing knife tip is more accurate at every turn, promote the simplification of product structure, abbreviate, design the theory as path boring cutter parent, distinctive double -end with the carbide pole, it is more economical and practical.
Description
Technical field
This utility model relates to a kind of novel hard alloy double end path boring cutter.
Background technology
Limited by workpiece aperture during original little hole machined, typically only take hands to whet a knife to solve, first hands is whetted a knife does not has size the most accurately, can only whet a knife with the experience of master worker, the life-span of opponent's knife milling tool and the outward appearance of product, dimensional requirement can not control, consumer instantly cannot be met to the outward appearance of product and size requirements, due to cutter processing be to produce certain heat to directly affect cutting-tool's used life and aesthetic finish, working (machining) efficiency low cost is high, thus adds the production cost of five metals processing industry and the minimizing of order.Now the most conventional processing aperture, at about 5mm, does not process the standard path boring cutter of below 5mm, so using from cutter and cannot processing less hole process principle.The contact adding workpiece centre in man-hour cannot be processed.Shortcoming is as follows: 1, original path boring cutter product structure and complex manufacturing technology need single open model die casting, and the design of single head blade is uneconomical, expends higher cost；2, cannot meet customer need；3, not having inner-cooling structure, cutter uses short, increases entreprise cost.
Utility model content
The purpose of this utility model is for drawbacks described above, it is provided that a kind of novel hard alloy double end path boring cutter.
This utility model solves its technical problem and be the technical scheme is that
A kind of novel hard alloy double end path boring cutter,
A kind of novel single head hole boring cutter, including cutter, described cutter includes knife bar, cutter head structure, described cutter head structure is two, described knife bar includes the cylindric body of rod being positioned at middle part, the two ends of the described cylindric body of rod connect a cutter head structure respectively, and the described cylindric body of rod constitutes a Knife handle structure, this Knife handle structure and the cutter head structure being connected on the cylindric body of rod other end with the cutter head structure being connected on wherein one end and constitutes cutter.
Described cutter head structure is on the extension of the described cylindric body of rod.
Described extension is provided with cutter head and for processing the supplementary structure of chip removal, described supplementary structure includes being positioned at the first inclined plane part on described extension, the second inclined plane part, the 3rd inclined plane part, described 3rd inclined plane part is across one of them side described in described extension formation, and described second inclined plane part, the first inclined plane part are arranged successively along the direction away from the described cylindric body of rod；The inclined-plane of described first inclined plane part connects with the inclined-plane of described 3rd inclined plane part and in the angle between 75 degree to 135 degree.
It is provided with arc transition between described 3rd inclined plane part and the described cylindric body of rod.
It is provided with arc transition between described first inclined plane part and the second inclined plane part.
Described first inclined plane part, the 3rd inclined plane part cooperatively form dual contact structure.
Beneficial effect
This utility model has the advantage that
1, distinctive dual contact, each tool changing point of a knife height location is more accurate；
2, the simplification of improving product structure, simplifies, with hard alloy pole as path boring cutter parent, distinctive dual head design theory, more economical material benefit；
3, distinctive path boring cutter same handle footpath can process multiple different pore size, can be used on different equipment such as numerically controlled lathe, CNC milling machine.Applied widely, more economical, easy；
4, the interior cold of innovation holds art, it is simple to processing chip removal and cutter cooling tool life, reduces processing cost.
Accompanying drawing explanation
Fig. 1 is one of embodiment schematic diagram of the present utility model；
Fig. 2 is the two of embodiment schematic diagram of the present utility model.
