Description

Multifunctional milling cutter for die industry

Technical Field

The utility model relates to the technical field of milling cutters, in particular to a multifunctional milling cutter for the die industry.

Background

Milling tools are rotary tools for milling machining having one or more cutter teeth. When in operation, each cutter tooth cuts off the allowance of the workpiece intermittently in sequence. Milling cutters are mainly used for machining planes, steps, grooves, forming surfaces, cutting workpieces, etc. on milling machines.

The curved surface and the plane are arranged on a machined workpiece in the die industry, the shape is relatively complex, the curved surface machining on the workpiece needs to be performed by using a spherical milling cutter for end milling machining, the plane machining on the workpiece needs to be performed by using a rough milling cutter and a finish milling cutter for side milling machining, and the machining of the workpiece can be completed by using a plurality of cutters in the whole machining process, so that the cost of the cutters is high, the machining time is long, and the improvement is needed.

Disclosure of Invention

The utility model aims at: in order to solve the problems, a multifunctional milling cutter for the die industry is provided.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:

a multifunctional milling cutter for the die industry comprises a cutter handle, wherein the cutter handle comprises a spherical blade part, a rough milling part and a finish milling part.

Preferably, the rough milling part is of a three-edge structure, the front edge surface of the peripheral edge is designed to be wavy, and the front angle and the helix angle of each point of the cutting edge are variable.

Preferably, the peripheral edge of the finish milling part is linear and has a six-edge structure.

Preferably, the milling cutter employs a nanocomposite coating.

In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows:

this application carries out profile processing through using the spherical sword of cutter terminal surface, and the preceding section part of cutter week sword adopts preceding ripples sword design, can carry out big surplus side milling process, and six sword finish milling cutter designs are adopted to cutter week sword rear end, can carry out finish machining to the work piece surface, has compounded three kinds of different cutting functions on same cutter, has reduced cutter use cost, has also reduced the tool changing time simultaneously and has promoted machining efficiency.

Legend description:

1. a spherical blade portion; 2. rough milling a machining part; 3. finish milling the part; 4. a knife handle.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, the present utility model provides a technical solution:

a multifunctional milling cutter for the die industry comprises a cutter handle 4, wherein the cutter handle 4 comprises a spherical blade part 1, a rough milling part 2 and a finish milling part 3.

Specifically, as shown in fig. 1, rough milling needs big surplus rough machining, and the in-process iron fillings are long, cutting vibration is big, and the front edge face of rough milling part 2 week sword designs to the wave, and the rake angle and the helix angle of each point position of blade all change, and the iron fillings can force the chip breaking through the front edge face of wave after forming, form the short bits, guarantee that the iron fillings are discharged more easily, also can eliminate cutting vibration simultaneously, promotes the cutting stability during big surplus rough machining, and rough milling part 2 designs to three sword structures, holds the bits space bigger, more is fit for rough machining.

Specifically, as shown in fig. 3, since the finish milling machining cutting allowance is small, the peripheral edge of the finish milling part 3 is linear, the roughness of the machined surface can be improved, the finish milling part 3 is designed into a six-edge structure, the number of teeth is more, the cutting allowance of each tooth can be reduced, and higher surface roughness can be obtained.

Specifically, as shown in fig. 1, the milling cutter adopts the nano composite coating, so that the surface roughness and the wear resistance of the cutter can be improved, and the cutter can have longer cutting life.

The previous description of the embodiments is provided to enable any person skilled in the art to make or use the present utility model. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model. Thus, the present utility model is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
