Technical Field
The utility model relates to a cutter technical field for the cutting process, concretely relates to adorn milling cutter blade immediately.
Background
The milling cutter is usually used for cutting tools of milling machines and processing machines, and in the existing milling cutter blade, because one surface of the blade has an angle and forms a reaction force with a locking screw, a screw hole for mounting the cutter head is subjected to a certain pulling force, and the screw hole of the cutter head is easy to be subjected to wire drawing after a long time, so that the cutter head is damaged, and the service life is short; in the existing blades, one blade only has two cutting edges, so that the milling speed is low and the required cost is high.
Accordingly, to address the above problems, there is a need for a milling cutter insert that overcomes the existing deficiencies.
SUMMERY OF THE UTILITY MODEL
To the not enough of above-mentioned prior art, the utility model aims to solve the technical problem that: how to provide a milling cutter blade of adorning immediately that can better mill processing, long service life, easy installation.
In order to solve the technical problem, the utility model discloses a following technical scheme:
the utility model provides a found dress milling cutter blade, includes the blade body, the cross sectional shape of blade body is parallelogram, the geometric center department of blade body is equipped with along thickness direction and is used for the mounting hole with blade disc fixed connection, two relative sides of circumference of blade body outwards dislocation are provided with the milling sword respectively, the same side of milling sword is provided with the cut-off groove, four sides of circumference of blade body still are provided with the locating surface.
Therefore, when the insert is used for milling, the surface of a workpiece can be better machined.
Further, the number of the milling edges is 4, and the milling edges are also provided with negative relief angles. By utilizing the plurality of milling edges, the processing speed can be improved, and the production cost of the cutter is reduced; the setting of negative relief angle has improved the intensity of milling sword, has increased the life of cutter, can be to better milling process of work piece.
Further, the mounting holes are arranged in a double-sided counter bore. Through the double-sided counter bore, reverse clamping on two sides can be carried out, the utilization rate of the cutter is improved, and the production cost of the cutter is reduced.
Further, the milling edge is connected with the cutting groove, and the cutting groove comprises two crossed inclined planes. The cutting groove is utilized to accelerate the discharge of scraps, improve the heat dissipation speed, prolong the service life of the cutter and reduce the influence on the surface to be processed of the workpiece.
Furthermore, the side edge of the blade body, which is not provided with the milling edge, is provided with a fillet, and the joint of the fillet and the milling edge is an arc. By utilizing the arc, the strength of the milling edge is increased, and the local stress of the chamfer tip in use is avoided.
Further, the locating surface is a zero back angle surface with an included angle of 80 degrees. By using the rear corner face, the reaction force caused by the rear inclined face after the screw is locked can be eliminated.
Further, the insert body is made of a cemented carbide material. Milling can be better performed by cemented carbide.
In conclusion, the blade can better process the surface of a workpiece, is easy to install, and has long service life, high processing efficiency and low cutter cost.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
During specific implementation, as shown in fig. 1-3, a vertical milling cutter blade comprises a blade body 1, the cross-sectional shape of the blade body is a parallelogram, a mounting hole 2 for fixedly connecting with a cutter head is formed in the geometric center of the blade body along the thickness direction, the side edges of the two surfaces of the blade body 1, which face away from each other in the circumferential direction, are respectively provided with a milling edge 7 in an outward staggered manner, the milling edge is provided with a breaking groove 4 in a concave manner on the same side edge, and four circumferential side surfaces of the blade body are also provided with positioning surfaces 5. Therefore, when the insert is used for milling, the surface of a workpiece can be better machined.
In this embodiment, the number of the milling blades is 4, and the milling blade is further provided with a negative relief angle 6. By utilizing the plurality of milling edges, the processing speed can be improved, and the production cost of the cutter is reduced; the arrangement of the negative relief angle 6 improves the strength of the milling blade, prolongs the service life of the cutter and can better mill a workpiece. Meanwhile, in order to ensure the performance of the front rake angle, the rake angle is machined in the proper width of the mounting surface. And each cutting edge is added with a negative back angle to improve the strength of the cutting edge.
In this embodiment, the mounting hole 2 is a double-sided counter bore. Through the double-sided counter bore, reverse clamping on two sides can be carried out, the utilization rate of the cutter is improved, and the production cost of the cutter is reduced.
In this embodiment, the milling edge 7 is connected to the cutting groove 4, and the cutting groove includes two intersecting inclined surfaces. The cutting groove is utilized to accelerate the discharge of scraps, improve the heat dissipation speed, prolong the service life of the cutter and reduce the influence on the surface to be processed of the workpiece.
In this embodiment, the side edge of the blade body, which is not provided with the milling edge, is provided with a fillet, and the joint of the fillet 3 and the milling edge is an arc. By utilizing the arc 8, the strength of the milling edge 7 is increased, and the local stress of the chamfer tip in use is avoided.
In this embodiment, the positioning surface 5 is a zero back angle surface with an included angle of 80 degrees. By using the rear corner face, the reaction force caused by the rear inclined face after the screw is locked can be eliminated.
In this embodiment, the insert body is made of cemented carbide material. Milling can be better performed by cemented carbide.
The milling cutter blade in the shape can complete the whole machining of 4 cutting edges and one clamping of the arc of the cutter point through the transposition of the manipulator, and the consistency of the cutting edges in the transposition is ensured.
The working principle and the flow of the mechanism are as follows:
when the milling cutter blade is used again, the blade is fixedly arranged on the cutter head, and the surface of a workpiece can be machined. The structure change of the mounting surface ensures that the screw hole of the cutter head is pulled to draw wires, thereby improving the safety performance in use. The blade is changed from two cutting edges into four cutting edges, so that the cutter cost of a client is greatly reduced, and meanwhile, the consumption of raw materials is saved.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art; the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
