Technical Field

The utility model relates to a cutter technical field specifically says so, is a shaping milling cutter of processing aluminum alloy casing.

Background

The aluminum alloy has low density, but the intensity is higher, be close to or exceed high-quality steel, the plasticity is good, can process into various section bars, has good electric conductivity, heat conductivity and corrosion resistance, use more extensively, when processing the casing hole that the aluminum alloy was made, at first will adopt the cutter to carry out primary processing to the hole, after the hole processing, in order to guarantee the surface quality and the roughness of work piece, still need to change the cutter and carry out processes such as hole bottom shaping, drill way tapering shaping and pore wall processing respectively, change the cutter every time and all need carry out the tool setting, the tool changing tool setting takes a long time, and many cutters are used for the processing of a work piece, machining efficiency is low, and the cost is higher.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the utility model aims at providing a processing aluminum alloy casing's shaping milling cutter. The hole bottom forming, the hole wall processing and the orifice taper forming are integrated, all the processing forming sizes of the workpiece to be processed, the orifice taper forming and the hole wall are combined together through one cutter to be processed, the processing beat of the cutter is improved, and the processing cost of the tool is reduced.

The technical scheme is as follows: in order to achieve the above object, the utility model provides a processing aluminum alloy casing's shaping milling cutter, including cutting part and stalk portion, the cutting part is equipped with knife tip R angle, downthehole wall side sword, circular arc shaping R angle and milling taper face, knife tip R angle sets up at the foremost of cutting part, and downthehole wall side sword sets up the rear side at knife tip R angle, and circular arc shaping R angle sets up the transitional coupling department between downthehole wall side sword and milling taper face, and the back of a knife blade extends to the stalk portion from knife tip R angle, and the chip groove sets up the both sides at the back of a knife blade.

Further, the arc forming R corner comprises a forming R corner I and a forming R corner II, the forming R corner I and the forming R corner II are adjacently arranged, and the arc radius of the forming R corner I is equal to that of the forming R corner II.

Further, the hole inner wall side edge is parallel to the horizontal center axis.

Furthermore, an included angle formed between the milling taper surface and the horizontal central axis is 15 degrees.

Further, the flute length of the chip groove is larger than half of the total length of the blade part and the handle part.

Further, the diameter of the edge of the inner wall side edge of the hole is smaller than the diameter of the shank.
