Example Embodiment

[0031] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0032] like figure 1 As shown in the figure, the present invention discloses a drilling assembly used for the drilling process of cemented carbide materials. The drilling assembly is used for drilling a cemented carbide material with a thickness of not more than 5 mm in the machining of a die in a clamp machine. .

[0033] The drilling assembly comprises a coaxially connected drill bit 1 , a tip set 3 and a shaft piece 5 . The drill bit 1 and the shaft member 5 are respectively disposed on both ends of the top-end sleeve 3 .

[0034] A snap-spring positioning piece 4 is also mechanically connected between the top sleeve 3 and the shaft member 5 .

[0035] A knurled segment 51 is provided on the end of the shaft member 5 opposite to the top end sleeve 3 .

[0036] like figure 2 As shown, the top sleeve 3 is configured as a cylindrical sha...

Abstract

The invention discloses a drilling component used for the drilling technique of hard alloy materials, which is used for drilling the hard alloy material with the thickness being not more than 5mm. The drilling component comprises a drill bit, a top end sleeve piece and a rod body piece which are connected coaxially; the drill bit and the drill body piece are arranged at both ends of the top end sleeve piece respectively, the end face of the top end sleeve piece, opposite to the drill bit, is provided with a center hole, an annular groove is arranged at an opening end of the center hole; the end face of the top end sleeve piece, opposite to the rod body piece, is provided with a connecting structure, a channel is arranged on the outer end face of the connecting structure; a tungsten steel drill bit used for the drill bit is arranged in the center hole of the top end sleeve piece in series; the end part of the drill bit is stretched out of the center hole of the top end sleeve piece; the rod body piece is connected with the top end sleeve piece through sheathing the connecting structure; a knurling section is arranged on one end of the rod body piece opposite to the top end sleeve piece, and the knurling section of the rod body piece is arranged in an externally connected spanner drill chuck in series. The drilling component is good in structure integrity, high in precision, low in cost, strong in generality, and wide in application scale; furthermore, the processing quality is improved.

Description

technical field [0001] The invention relates to a clamp processing assembly, in particular to a drilling assembly used in the drilling process of cemented carbide materials. Background technique [0002] At present, in the manufacture of small and medium-sized motor molds, it is often necessary to prepare special tooling to match the manufacture of mold parts. Some special mold tooling needs to be drilled with cemented carbide materials, and assembled into special tooling after completion. [0003] Special tooling in mold manufacturing often uses discarded carbide milling inserts. Usually shaped and drilled. The shape processing often adopts the wire cutting process; for drilling, if the twist drill is directly used for drilling, since the hardness of the twist drill itself is far less than that of the cemented carbide material, this process is obviously not suitable. Contents of the invention [0004] The invention provides a drilling assembly used for the drilling proc...
