Abstract

The utility model belongs to the field of cutters, in particular to a finish machining molding cutter used for machining an aluminum alloy shell body. The finish machining molding cutter comprises a cutter handle connected with a machining machine tool. A connecting rod with the small diameter is arranged at the front end of the cutter handle. The connecting rod is connected with a cutting part. The cutting part comprises an end face cutting edge, a first slant cutting edge, a side cutting edge and a second slant cutting edge. An included angle with 90 degrees is formed between the first slant cutting edge and the second slant cutting edge. According to the finish machining molding cutter, a plurality of faces to be machined can be machined at the same time, needed shapes can be machined at one time, and therefore production efficiency is high, and machining precision is guaranteed at the same time.

Description

Fine finishining moulding cutter
Technical field
The utility model belongs to the cutter field, and is particularly a kind of for the accurately machined forming cutter of processing Al-alloy casing.
Background technology
Traditional is processed into profile in enclosure interior, can process by boring cutter or milling cutter, when producing the notebook housing, also need inner forming surface is processed, because the volume of notebook housing is less, and border seal, the inner space is limited, and the machined surface of traditional cutting edge is more single, can't process a plurality of faces of processing that need simultaneously, need repeatedly tool changing and workpiece to relocate just and can finish needed processing, the time of expending like this is more, and operating efficiency is also lower, can't satisfy need of production.
Summary of the invention
For the deficiencies in the prior art, the utility model has designed a kind of for accurately machined forming cutter, and it can be finished simultaneously a plurality of to be processed processing, and the shape that time processing goes out to need has higher production efficiency, also guarantees simultaneously the precision of processing.
The utility model is achieved through the following technical solutions:
Fine finishining moulding cutter, it comprises the handle of a knife that is connected with machining tool, the front end of described handle of a knife arranges the less connecting rod of diameter, described connecting rod is connected with cutting portion, described cutting portion comprises face cutting edge, the first inclined-plane cutting edge, side cut sword and the second inclined-plane cutting edge, and the angle between described the first inclined-plane cutting edge and the second inclined-plane cutting edge is 90 °.
Son is established in the junction of described handle of a knife and connecting rod taper seat, and the taper seat of setting forms one and allows bit space, prevents from touching workpiece at the process handle of a knife.
Described cutting portion skin is provided with tungsten carbide coating, hardness and the resistance to elevated temperatures of the tungsten carbide coating energy Effective Raise cutting portion of setting, the cutting ability and the service life that are conducive to improve cutter.
In sum, the utility model has designed the forming cutter that a kind of fine finishining is used, can time processing needed shape out, need not repeatedly to change cutter and relocate, the time processing moulding can effectively be shortened man-hour, enhance productivity, also guaranteed the precision of processing simultaneously.
Description of drawings
Fig. 1 is structural representation of the present utility model;
1 is handle of a knife among the figure, and 2 is taper seat, and 3 is connecting rod, and 4 is the second inclined-plane cutting edge, and 4 are the side cut sword, and 6 is the first inclined-plane heat in metal cutting, and 7 is face cutting edge.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Fine finishining moulding cutter as shown in Figure 1, it comprises the handle of a knife 1 that is connected with machining tool, the front end of described handle of a knife 1 arranges the less connecting rod of diameter 3, described connecting rod 3 is connected with cutting portion, described cutting portion comprises face cutting edge 7, the first inclined-plane cutting edge 6, side cut sword 5 and the second inclined-plane cutting edge 4, and the angle between described the first inclined-plane cutting edge 6 and the second inclined-plane cutting edge 4 is 90 °.
Described handle of a knife 1 is established son with the junction of connecting rod 3 taper seat 2, and the taper seat of setting forms one and allows bit space, prevents from touching workpiece at the process handle of a knife.
Described cutting portion skin is provided with tungsten carbide coating, hardness and the resistance to elevated temperatures of the tungsten carbide coating energy Effective Raise cutting portion of setting, the cutting ability and the service life that are conducive to improve cutter.
In sum, the utility model has designed the forming cutter that a kind of fine finishining is used, can time processing needed shape out, need not repeatedly to change cutter and relocate, the time processing moulding can effectively be shortened man-hour, enhance productivity, also guaranteed the precision of processing simultaneously.
