Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing.

[0020] see figure 1 , figure 2 and image 3 , as can be seen from the figure, the metal workpiece disposable forming knife of the present invention includes a main knife seat 1, and an integrally formed knife handle 2 is provided on the upper surface of the main knife seat 1, and the knife handle 2 is used to connect with the power shaft. A drilling reamer is provided at the center position of the lower surface of the main tool seat 1, and two waste slag grooves 3 drawn through are provided in the vertical direction of the drilling reamer, so that the drilling reamer rotates symmetrically along its own rotation center. The drill reamer is composed of an upper and lower drill reamer body for processing different apertures formed in one piece, wherein the drill reamer body 4 for processing a coarse aperture is located between the main tool holder 1 and the drill reamer bod...

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...
