Abstract
The utility model belongs to the field of knives, and in particular relates to a shell clamping groove T-shaped knife. The T-shaped knife comprises a knife handle, and one end of the knife handle is connected with a T-shaped knife part. The T-shaped knife is characterized in that the T-shaped knife part comprises a connecting rod part connected with the knife handle and a cutting part connected with the connecting rod part, and the cutting part is provided with a spiral cutting edge. Through the T-shaped knife matched with a shell clamping groove in shape, the clamping groove in a shell can be machined at one time, and the problem that the knife cannot be fed in conventional machining can be effectively solved; and a tungsten carbide coating arranged on the knife can effectively improve the heat resistance of the knife and is beneficial to long-time use of the knife, and the requirement on continuous production is met.
Description
Technical field
The utility model belongs to the cutter field, particularly a kind of T-shaped cutter of moulding of enclosure draw-in groove.
Background technology
Traditional processes draw-in groove in enclosure interior, can process by boring cutter or milling cutter, when producing the notebook housing, also need more inner draw-in grooves are processed, because the volume of notebook housing is less, and border seal, the inner space is limited, and traditional process tool can't stretch into housing, namely can't finish the processing to the enclosure interior draw-in groove.
Summary of the invention
For the deficiencies in the prior art, the utility model has designed a kind of T-shaped cutter that can process the draw-in groove on the notebook computer shell according to the shape of actual working position.
The utility model is achieved through the following technical solutions:
The T-shaped cutter of shell draw-in groove, it comprises handle of a knife, an end of described handle of a knife is connected with T-shaped cutter section, it is characterized in that: described T-shaped cutter section comprises the link rod part that is connected with handle of a knife and the cutting portion that is connected with link rod part, is provided with the spiral cutting sword on the described cutting portion.
Be provided with four cutting edges on the described cutting portion, be provided with the stationarity that four cutting edges are conducive to cut, guarantee cutting effect.
The surface of described cutting portion is provided with tungsten carbide coating, and the tungsten carbide coating of setting is conducive to improve the heat-resisting quantity of cutter, is conducive to the long-time time of cutter, satisfies need of production.
One end of described handle of a knife is provided with taper seat, and the taper seat of setting forms one and allows bit space, avoids that workpiece and handle of a knife touch in the process.
In sum, the utility model has designed a kind of T-shaped cutter that coincide with shell draw-in groove shape, can process at one time the draw-in groove on the shell, simultaneously can effectively overcome the problem that traditional processing can't be descended cutter, the heat resistance of the tungsten carbide coating energy Effective Raise cutter that arranges on the cutter simultaneously, be conducive to the long-time use of cutter, satisfy the quantity-produced needs.
Description of drawings
Fig. 1 is the structural representation of the T-shaped cutter of shell draw-in groove;
1 is handle of a knife among the figure, and 2 is taper seat, and 3 is connecting portion, and 4 is cutting portion.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The T-shaped cutter of shell draw-in groove as shown in Figure 1, it comprises handle of a knife 1, one end of described handle of a knife 1 is connected with T-shaped cutter section, it is characterized in that: described T-shaped cutter section comprises the link rod part 3 that is connected with handle of a knife 4 and the cutting portion 4 that is connected with link rod part, is provided with the spiral cutting sword on the described cutting portion 1.
Be provided with four cutting edges on the described cutting portion 4, be provided with the stationarity that four cutting edges are conducive to cut, guarantee cutting effect.
The surface of described cutting portion 4 is provided with tungsten carbide coating, and the tungsten carbide coating of setting is conducive to improve the heat-resisting quantity of cutter, is conducive to the long-time time of cutter, satisfies need of production.
One end of described handle of a knife 1 is provided with taper seat 2, and the taper seat of setting forms one and allows bit space, avoids that workpiece and handle of a knife touch in the process.
In sum, the utility model has designed a kind of T-shaped cutter that coincide with shell draw-in groove shape, can process at one time the draw-in groove on the shell, simultaneously can effectively overcome the problem that traditional processing can't be descended cutter, the heat resistance of the tungsten carbide coating energy Effective Raise cutter that arranges on the cutter simultaneously, be conducive to the long-time use of cutter, satisfy the quantity-produced needs.
