Abstract

The utility model discloses a boring cutter used for machining an ejector rod hole. The boring cutter used for machining the ejector rod hole comprises a cutter handle and a cutter head. A cutting section and a transition section are arranged at the front end of the cutter head, wherein the cutting section and the transition section are integrally formed. The cutting section is in a reverse conical shape, two cutting edges are symmetrically arranged at the front end of the cutting head along a shaft, and the rear end of the transition section is connected with the front end of the cutter handle in a welding mode. According to the structure, the defects that an integrally-formed boring cutter is large in machining difficulty, time-wasting and material-wasting, a boring cutter with one edge is low in machining speed and low in accuracy, and the like are overcome, the improved boring cutter is provided, the two cutting edges are arranged on the cutter head, the machining speed and the machining accuracy are improved, meanwhile internal toughness of a cutter body is improved, and the boring cutter used for machining the ejector rod hole is not easily broken.

Description

A kind of boring cutter of processing jogger hole

Technical field

The utility model belongs to field of machining, particularly a kind of boring cutter of processing jogger hole.

Background technology

In the prior art, the boring cutter that is used for the jogger hole on the processing mold, the general single cutting-edge that adopts, the working (machining) efficiency of single cutting-edge boring cutter is low, and in working angles, the chip removal of cutting edge boring cutter is not smooth, cause being subjected to force unbalance, cause the fracture of handle of a knife easily, boring cutter adopts one-body molded, has increased technology difficulty and the cost of making boring cutter.

The utility model content

Technical problem to be solved in the utility model provides a kind of boring cutter of processing jogger hole, can improve working (machining) efficiency, reduces difficulty and the cost of making boring cutter simultaneously.

In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of boring cutter of processing jogger hole, comprise handle of a knife and cutter head, and described cutter head front end is provided with integrated segment of cutting and changeover portion; It is tapered that described segment of cutting is rounding, and its front end edge is axially arranged with two blades of symmetry;

Wherein, the rear end of changeover portion is inserted the handle of a knife front end and is welded to connect.

Advantage: 1, the cutter head segment of cutting is provided with two blades, has guaranteed process velocity and precision.2, handle of a knife and cutter head plug-in type are welded to connect, cutter head inserts welding in the handle of a knife, makes that the contact-making surface of cutter head and handle of a knife is more, has not only alleviated the integrated difficulty of processing of cutter, and than handle of a knife, cutter head directly weld firm fixed stronger, guaranteed the rigidity of boring cutter.3, the cutter head segment of cutting is designed to turbination, and the big afterbody of head is slightly little, is beneficial to the feeding cutter, prevents that segment of cutting is stuck.

Description of drawings

The specific embodiment

Shown in Fig. 1, the utility model is a kind of boring cutter of processing jogger hole, comprises handle of a knife 1 and cutter head 2, and described cutter head 2 front ends are provided with integrated segment of cutting 3 and changeover portion 4, it is tapered that described segment of cutting 3 is rounding, and its front end edge is axially arranged with two blades 5 of symmetry; Wherein, the rear end of described changeover portion 4 is inserted handle of a knife 2 front ends and is welded to connect.

Above-described only is preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.

Claims

1. a boring cutter of processing jogger hole comprises handle of a knife and cutter head, it is characterized in that: described cutter head front end is provided with integrated segment of cutting and changeover portion; It is tapered that described segment of cutting is rounding, and its front end edge is axially arranged with two blades of symmetry;
