Abstract

The utility model discloses a tungsten steel formed milling cutter for aluminum. The tungsten steel formed milling cutter for aluminum comprises a cutter handle; a cutter bit is formed in the cutter handle and consists of a first cutter blade part, a second cutter blade part, a third cutter blade part and a fourth cutter blade part which are connected sequentially; a vertical side blade is formed on the first cutter blade part; a side blade oblique upward is formed on the second cutter blade part; a circular arc side blade is formed on the third cutter blade part; a side blade oblique downward is formed on the fourth cutter blade part. According to the utility model, tungsten steel is used for manufacturing a formed milling cutter, so that the jumping of the milling cutter is reduced; the fact that grooves of bottleneck shapes are processed by utilizing the formed milling cutter becomes a reality, thereby guaranteeing that size precision and shapes of processed workpieces are consistent, and improving the production efficiency.

Description

A kind of aluminium tungsten steel forming milling cutter

Technical field:

The utility model relates to the technical field of milling cutter, more specifically to aluminium tungsten steel forming milling cutter.

Background technology:

Profile milling cutter cutting edge profile is according to the milling cutter of workpiece profile design, and it can ensure dimensional accuracy, the shape one of the workpiece to be machined higher productivity ratio of making peace.But the general present situation of groove of existing profile milling cutter institute milling is generally fairly simple, its shape is generally common square groove, dovetail groove etc., but in the time of the comparatively complicated groove of some planforms of processing, there is certain beating in its bottom because of milling cutter, the angle of inclination that the structural plane that some are less and precision are higher can not moulding.So process now some while having the groove compared with bottle neck shape, it can only repeatedly process milling cutter with many, the shape of its multiple workpiece is unanimously poor, has scale error, and process is consuming time takes great energy again, and production efficiency is lower.

Utility model content:

The purpose of this utility model is exactly the deficiency for prior art, and aluminium tungsten steel forming milling cutter is provided, and it utilizes wolfram steel to make profile milling cutter, has reduced beating of milling cutter, and the groove that uses profile milling cutter to process some bottleneck shapes becomes reality.

For achieving the above object, a kind of aluminium of the present utility model comprises handle of a knife with tungsten steel forming milling cutter, on handle of a knife, form cutter head, cutter head is made up of the first blade part being connected in turn, the second blade part, the 3rd blade part and four blade blade, on the first described blade part, form vertical side edge, the second blade part forms acclivitous side edge, and the 3rd blade part 23 forms the side edge of circular arc type, and four blade blade forms downward-sloping side edge.

As technique scheme preferably, the angle α that the second described blade part cross section two inclined lateral side form is between 31.05 °～31.15 °, the angle β that four blade blade cross section two inclined lateral side form is between 93.15 °～93.25 °, and the arc radius of the 3rd blade part is 0.5mm.

As technique scheme preferably, described handle of a knife and cutter head all adopt wolfram steel, the diameter of the first blade part of cutter head equals the diameter of handle of a knife.

The beneficial effects of the utility model are: it utilizes wolfram steel to make profile milling cutter, reduce beating of milling cutter tip, the groove that uses profile milling cutter to process some bottleneck shapes becomes reality, thereby ensures that dimensional accuracy, the shape of workpiece to be machined are consistent, has improved production efficiency.

Brief description of the drawings:

Below in conjunction with accompanying drawing, the utility model is described further:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the enlarged diagram at A place in Fig. 1 of the present utility model.

Symbol description in figure:

10, handle of a knife; 20, cutter head; 21, the first blade part; 22, the second blade part; 23, the 3rd blade part; 24, four blade blade.

Detailed description of the invention:

See shown in Fig. 1 and Fig. 2: aluminium of the present utility model tungsten steel forming milling cutter comprises handle of a knife 10, on handle of a knife 10, form cutter head 20, cutter head 20 is made up of the first blade part 21, the second blade part 22, the 3rd blade part 23 and the four blade blade 24 that are connected in turn, on the first described blade part 21, form vertical side edge, the second blade part 22 forms acclivitous side edge, the 3rd blade part 23 forms the side edge of circular arc type, and four blade blade 24 forms downward-sloping side edge.

The angle α that the second blade part 22 cross section two inclined lateral side form is between 31.05 °～31.15 °, and the angle β that four blade blade 24 cross section two inclined lateral side form is between 93.15 °～93.25 °, and the arc radius of the 3rd blade part 23 is 0.5mm.

Described handle of a knife 10 and cutter head 20 all adopt wolfram steel, and the diameter of the first blade part 21 of cutter head 20 equals the diameter of handle of a knife 10.

Operation principle: the utility model uses wolfram steel to make handle of a knife 10 and the cutter head 20 of its profile milling cutter, because adopting, wolfram steel there is stronger hardness and bending resistance deformation intensity, it can effectively reduce the beating of milling cutter tip of operation process, on cutter head 20, form several knife edge parts of similar bottleneck shape of cross section, the cutter head of milling cutter can carry out Milling Process to less structural plane in the situation that of small beating, simultaneously because wolfram steel hardness is larger, the cutter head 20 of its making is not easy to wear, thereby ensure its dimensional accuracy of producing workpiece, improved production efficiency.

Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
