Embedded groove type clamp spring assembly and method for drilling hard alloy materials by using embedded groove type clamp spring assembly

Abstract

The invention discloses an embedded groove type clamp spring assembly and a method for drilling hard alloy materials by using the embedded groove type clamp spring assembly. The embedded groove type clamp spring assembly comprises a drilling bit, a top end external member, a rod body piece and a clamp spring positioning piece. The method for drilling hard alloy materials by using the embedded groove type clamp spring assembly comprises the following steps of: step 1, fixing the hard alloy materials; step 2, clamping the embedded groove type clamp spring assembly through a spanner drill chuck; and step 3, drilling the hard alloy materials. The embedded groove type clamp spring assembly and the method for drilling hard alloy materials by using the embedded groove type clamp spring assembly can effectively drill through holes, the appearance of the through holes is complete, the whole machining process is stable, and machining is facilitated.

Description

technical field [0001] The invention relates to a drilling process and an embedded circlip assembly for hard alloy materials with a thickness not greater than 5 mm in the processing of molds in the clamp bed, in particular to an embedded circlip assembly and its application to cemented carbide materials. The method of drilling. Background technique [0002] 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, th...

Problems solved by technology

However, the overall processing force strength is still not high enough, and the connection between the top kit and the shaft is only supported by spot welding, so it is difficult to ensure a stable state during the entire processing

Especially when the drilling speed of the spindle of the drilling machine is high, the parts in the processing assembly are prone to "breakage" or even "throwing" out when the winding degree increases.

cause injury to the operator

[0011] Also, although the spot welds "join" the tip kit and shaft piece welded together, in practice it is extremely inconvenient to disassemble

If the force is not appropriate, it will cause friction between the top kit and the shaft, causing the size of each component to be deformed, resulting in damage to the fittings of the components, resulting in assembly loss

[0012] Therefore, it is difficult for the above three traditional processes to complete the drilling process for cemented carbide materials.
