Abstract
The utility model relates to a broaching tool used for processing the surface, spiral internal splines, groove patterns, complex mortises and the like, in particular to a Christmas tree mortise broach. The mortise broach comprises a broach body and a broach handle connected with the broach body. The broach body comprises a guiding part and a forming part, wherein the cross section of the lower half portion of broach body is in a rectangular shape, the cross section of the upper half portion of the broach body is provided with a Christmas tree mortise, the angle of 20 degrees is formed by a positioning line A and an axis B of the Christmas tree mortise, a lead angle groove with the angle of 15 degrees is formed by the guiding part and the forming part, an installing hole is formed in the broach handle, and the end face of one side of the broach handle is slantly arranged with 85 degrees. The broaching tool is simple and reasonable in structure, and high in intensity, abrasive resistance and precision.
Description
Technical field
The utility model relates to the broaching cutters that a kind of finished surface, internal helix spline, groove line and complicated tongue-and-groove etc. use, a kind of Christmas tree tongue-and-groove broaching tool specifically.
Background technology
Christmas tree tongue-and-groove broaching tool is to replace the processing such as the milling of product, plane, mill, the processing of some piece surface in being specially adapted to produce in enormous quantities at processing surface, plane, molded surface, groove line and the complicated tongue-and-groove of various profiles and tenon.But due to unreasonable on the use of material and structural design, make and have certain shortcomings and deficiencies in production and processing, thereby cause product can not satisfy the requirements such as technology and use, be in particular in: project organization is unreasonable, precision, intensity, wearability and processing performance bad, service life is low, processing cost is high, reduces its utilization rate.
Summary of the invention
The purpose of this utility model is that a kind of simple and reasonable, high strength, high-wearing feature, high-precision overall structure Christmas tree tongue-and-groove broaching tool will be provided.
The purpose of this utility model is to realize like this, this tongue-and-groove broaching tool comprises cutter hub, the handle of a knife that connects cutter hub, described cutter hub comprises the shaped portion that targeting part that the latter half section is rectangular and the first half section are provided with the Xmas-tree tongue-and-groove, the position line A of described Xmas-tree tongue-and-groove becomes 20 ° of angles with axis B, and targeting part and shaped portion have the lead angle groove at 15 ° of angles, offer installing hole on described handle of a knife, and a side end face of handle of a knife 2 becomes 85 ° of overturning angle settings.
The utlity model has following advantage and good effect:
1, the utility model is owing to adopting said structure, satisfied client's instructions for use, scientific and reasonable, install, the location is convenient, firmly.Christmas tree tongue-and-groove broaching tool is mainly used in processing the parts on aircraft, train, steamer, steam turbine etc.
2, the utility model has replaced the processing technology modes such as product mills, plane, mill, has promoted utilization rate, cuts down finished cost, shortens the production cycle to product, has effectively improved production efficiency.
3, the utility model is due in material and structural renewal thereof, adopt cobalt high speed steel W2Mo9Cr4Vco8 material to make, overcome the shortcoming and defect of prior art, not only guarantee serviceability and processing request that it is good, increase the service life, improve machining accuracy and improve the surface quality of product to be processed.
