One-step molding knife for metal workpiece

Abstract

The invention discloses a one-step molding knife for a metal workpiece. A drilling reamer is detachably mounted at the center position of the lower surface of a main knife holder through a locking screw and consists of drilling reamer bodies which are integrally formed and are used for processing different apertures, wherein the drilling reamer body for processing a thick aperture is positioned between the main knife holder and the drilling reamer body for processing a thin aperture; two sides of the lower surface of the main knife holder downwards extend to form additional knife holders; cutting blades are detachably mounted on the additional knife holders through locking screws; cutting edges of the cutting blades consist of two vertical cutting edges which are integrally formed and are used for cutting different diameters. The one-step molding knife for the metal workpiece can be used for processing a steplike hole and an outer surface step of a workpiece according to a requirement or only selectively processing the steplike hole of the workpiece or only processing the outer surface step of the workpiece; furthermore, the one-step molding knife can process the steplike hole or the step or both the steplike hole and the step by one step, so that the efficiency is greatly improved.

Description

technical field [0001] The invention relates to mechanical processing equipment, in particular to a disposable forming knife for a metal workpiece, which can process stepped holes and steps on the circumference of the workpiece at one time, and belongs to the technical field of cutting tools. Background technique [0002] Holes with different structures need to be processed on many workpieces. Most of the holes are straight holes. This kind of hole is often easier to process. It can be processed by a tool at one time, just by changing tools of different sizes. For common stepped holes, that is, two connected holes located on the same axis have different sizes. If you use conventional tools, you cannot process them at one time. Another hole of the required size is machined on the hole wall with a boring tool. Since it is processed in two steps, and the boring tool is inherently slower than the drill bit, the efficiency is relatively low when processing the stepped hole. I...

Problems solved by technology

According to the current processing method, it can only be processed in sections, and the large-diameter surface is processed first, and then the small-diameter surface is processed, which also has the problem of low efficiency.

If you want to process the stepped hole and the step on the circumferential surface at the same time, you need four steps to complete it, which is less efficient and cannot even meet the actual needs
