Abstract

The utility model discloses a kind of endless knife for processing cannelure, described endless knife is a drill bit (1), and the diameter of described drill bit (1) equals the external diameter of cannelure; The head of described drill bit (1) has a groove (2) and two knifes edge (3), and the width of described groove (2) equals the internal diameter of cannelure, and the degree of depth of described groove (2) equals the groove depth of cannelure; Described two knifes edge (3) are positioned at the both sides of described groove (2), and the width of two knifes edge is equal, and width is the groove width of cannelure.Endless knife of the present utility model improves the working (machining) efficiency of cannelure; Expensive numerical control machining center can be replaced and use cheap drilling machine to carry out the processing of cannelure, reducing processing cost.

Description

A kind of endless knife for processing cannelure
Technical field
The utility model belongs to metal cold manufacture field, and particularly, the utility model relates to a kind of endless knife for processing cannelure.
Background technology
The part with cannelure is often needed in machining.The traditional diamond-making technique of cannelure is processed by CNC milling machine or machining center milling tool in the mode of NC Interpolation.As shown in Figure 1, traditional processing mode of cannelure is: find the center of workpiece (the left figure as in Fig. 1) with Digit Control Machine Tool; The degree of depth that workpiece needs is penetrated with the milling tool that diameter equals cannelure; The interpolation track (shown in figure dashed centre line as right in Fig. 1) of cutter is controlled by Digit Control Machine Tool; When cutter interpolation complete center circle, milling cutter mills away all workpiece materials of milling cutter bus process and forms cannelure.The major defect of this cannelure processing mode is that processing cost is high, and working (machining) efficiency is not high.
The development of line cutting technology makes to be reprocessed into as possibility high-speed steel drill.Utilize linear cutting equipment high-speed steel drill can be cut into required cross sectional shape, drill bit is the various irregularly-shaped hole of energy drilling just; Such as stepped hole, cannelure etc.
Utility model content
The purpose of this utility model is, provide a kind of endless knife for processing cannelure, this endless knife improves the working (machining) efficiency of cannelure, reduces processing cost.
For achieving the above object, the utility model adopts following technical scheme:
For processing an endless knife for cannelure, described endless knife is a drill bit 1, and the diameter of described drill bit 1 equals the external diameter of cannelure; The head of described drill bit 1 has a groove 2 and two knifes edge 3, and the width of described groove 2 equals the internal diameter of cannelure, and the degree of depth of described groove 2 equals the groove depth of cannelure; Described two knifes edge 3 are positioned at the both sides of described groove 2, and the width of two knifes edge is equal, and width is the groove width of cannelure.
Endless knife of the present utility model improves the working (machining) efficiency of cannelure; Expensive numerical control machining center can be replaced and use cheap drilling machine to carry out the processing of cannelure, reducing processing cost.

Fig. 1 is the processing mode of traditional endless groove;
Fig. 2 is the profile of the endless knife of the utility model embodiment;
Fig. 3 is the schematic diagram of the endless knife processing cannelure by the utility model embodiment.
Accompanying drawing identifies
1, drill bit 2, groove 3, two knifes edge
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 2, a kind of endless knife for processing cannelure, described endless knife is a drill bit 1, and the diameter of described drill bit 1 equals the external diameter of cannelure; The head of described drill bit 1 has a groove 2 and two knifes edge 3, and the width of described groove 2 equals the internal diameter of cannelure, and the degree of depth of described groove 2 equals the groove depth of cannelure; Described two knifes edge 3 are positioned at the both sides of described groove 2, and the width of two knifes edge 3 is equal, and width is the groove width of cannelure.
The making step of described endless knife is as follows:
101) diameter is selected to equal the unit-type drill head of cannelure external diameter;
For reducing production cost, the drill bit scrapped generally can be selected;
102) with Linear cut, the head cutter of drill bit is gone out a groove and two knifes edge;
The width of described groove 2 equals the internal diameter of cannelure, and the degree of depth of described groove 2 equals the groove depth of cannelure; Described two knifes edge 3 are positioned at the both sides of described groove 2, and the width of two knifes edge 3 is equal, and width is the groove width of cannelure.
103) with two knifes edge 3 described in abrasive machine sharpening.
As shown in Figure 3, as follows by the step of described endless knife processing cannelure:
201) with two of described endless knife knifes edge 3 for benchmark finds the relative position with workpiece;
202) described endless knife rotates along the axis (the described axis of drill bit 1 and the main-shaft axis of lathe) of oneself;
203) along with the downward incision of described endless knife, described two knifes edge 3 constantly fall to form cannelure workpiece material drilling.

Claims (1)
