Sleeve embedding groove type clamp spring component and method for boring thick-plate type hard alloy

Abstract

The invention discloses a sleeve embedding groove type clamp spring component and a method for boring a thick-plate type hard alloy. The sleeve embedding groove type clamp spring component comprises a drill bit, a top end sleeve, a rod body piece, a clamp spring positioning piece and a sleeve. The method for boring the thick-plate type hard alloy by using the sleeve embedding groove type clamp spring component comprises the following steps: step 1. fixing the hard alloy material; step 2. clamping the sleeve embedding groove type clamp spring component through a spanner drill chuck; and step 3. boring the hard alloy material. By the adoption of the sleeve embedding groove type clamp spring and the method, through holes can be effective bored, the appearance is complete, the state of the entire machining process is stable; and moreover, the sleeve embedding groove type clamp spring and the method are beneficial to process.

Description

technical field [0001] The invention relates to a drilling process for hard alloy materials with a thickness of 5 to 10 mm in the processing of molds on a clamp bed, and a sleeve-embedded circlip assembly, in particular to a sleeve-embedded circlip assembly and its thickness adjustment. The method of plate type cemented carbide 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 ma...

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.
