Description

TECHNICAL FIELD

[0001] The utility model belongs to fine processing technical field, more specifically, it is especially related to a wheel hub cutter with chip breaker. BACKGROUND

[0002] In the process of machining the rim, the aluminum chips are not easy to be discharged due to winding, and the workpiece is easy to be scratched. The conventional alloy blade generally has a chip breaking groove during pressing, which can play a role in chip breaking when machining the wheel hub workpiece. However, with the improvement of machining process, diamond (PCD) blades are widely used in the field of wheel hub machining. Diamond (PCD) blades not only increase the service life of the blade, save the tool changing time, thereby controlling the cost, but also can get a better smooth surface with roughness. The diamond (PCD) blade is generally welded on the alloy base body by a diamond blank. The diamond blank is usually a planar structure, and cannot be pressed into a chip breaking groove shape, so it cannot meet the requirements of chip breaking cutting, and therefore a function of chip breaking needs to be designed on the diamond (PCD) blade.

[0023] The embodiment of the utility model will be further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model.

[0024] In the description of the utility model, unless otherwise specified, the meaning of "multiple" is two or more than two;The orientation or position relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail" and the like is based on the orientation or position relationship shown in the drawing, and is only for the convenience of describing the utility model and simplifying the description, and cannot be understood as indicating or implying that the indicated device or element must have a particular orientation, a particular orientation and operation, therefore, it cannot be understood as limiting the utility model. In addition, the terms "first", "second", "third" and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0025] In the description of the utility model, it is necessary to explain that, unless there is definite stipulation and limitation, the term "connects", "connects" should be broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connects, can be mechanical connection, also can be electrical connection, can be direct connection, also can indirectly connect through intermediate medium.

[0026] Embodiment:

[0027] As shown in the accompanying Figure 1 to the accompanying Figure 7 As shown:

[0028] A hub cutter with a chip breaker, comprising a cutter body 1, one end of the cutter body 1 is provided with a cutter head 11;

[0029] Chip breaker 2, the chip breaker 2 is arranged at the same end with the cutter head 11 and is located at the bottom of the cutter head 11, the edge of the chip breaker 2 is provided with a welding positioning edge 21, the thickness of the chip breaker 2 is H, the upper surface of the chip breaker 2 is provided with a chamfer, and the chamfer angle is R. The chip breaker 2 is arranged in a circular arc structure, and the chip breaker 2 is welded on the cutter body 1. The cutter body 1 is arranged in an I-shaped structure. The gap between the edge of the chip breaker 2 and the cutter body 1 is X, and X is greater than the cutting depth. The width of the gap X between the edge of the chip breaker 2 and the cutter body 1 is 0.2mm~1.5mm. The thickness H of the chip breaker 2 is 0.5mm~2mm. The chamfer angle R is 20°~60°.

[0030] Meanwhile, the chip breaker 2 and the cutter body 1 in the scheme are not necessarily arranged concentrically, and can be arranged eccentrically or in an ellipse or other special shape. The advantage of the different concentricity in the scheme is that different cutting depths are achieved according to different positions, and different chip breaking effects are achieved.

[0031] The utility model connects a hard alloy chip breaker on the diamond rake face, makes the aluminum chip small in the processing process, prevents long aluminum chip winding, satisfies the requirement of small chip in unmanned workshop. Connect a chip breaker on the R type hub blade, so that the purpose of chip breaking is achieved in the processing process, as follows: the chip breaker 2 adjusts the X size according to the cutting depth of the blade part, S is the positioning edge, prevents the chip breaker from deviating during welding, H is the thickness of the chip breaker, and R is the chip breaking angle.

[0032] The blade determines the X size according to the cutting depth when machining the rim, wherein the X size width is greater than the cutting depth, further, the size of the chip breaker is determined, the S welding positioning edge is machined, the appropriate R and thickness H are selected, and the chip breaker and the PCD blade blank are connected together through vacuum welding, and it is necessary to note that the welding needs to keep the chip breaker and the PCD blade blank concentric. After the welding, the PCD blade edge is machined. When the blade is machined, the aluminum chip is broken after being hit on the inclined surface of the chip breaker through the rake face, so that the chip breaking purpose is achieved.
