Description
Technical field
The utility model relates to cutting technology field, and in particular, it relates to a kind of rose cutter.
Background technology
Ball head knife is for cutting the cutter of various curved surface, arc groove on the assembling of the similar bulb of blade and milling machine.Rose cutter also referred to as R cutter, rose cutter can milling mould just, cast iron, carbon steel, steel alloy, tool steel, general iron material.
But in the prior art, rose cutter usually easily produces vibration because of blade part when cutting easily makes blade part rupture, namely the insufficient strength between blade part and handle of a knife, and when cutting, the scrap produced is not easy to discharge, cause the tool surfaces of cutting smooth not, therefore need to propose a kind of better scheme and solve this problem.
Utility model content
For the deficiency that prior art exists, it is high that the purpose of this utility model is to provide a kind of intensity, cuts the smooth surface of smooth guarantee workpiece, and easily can derive the ball cutter cutting scrap.
For achieving the above object, the utility model provides following technical scheme: a kind of rose cutter, comprise shank section and blade part, described blade part comprises the first blade and the second blade, described first blade and the second blade are symmetrical arranged, described first blade and the second blade form dead point in junction, described dead point width accounts for 1/4 of the tread of the first blade or the second blade, described blade part also comprises the first auxiliary knife edge and the second auxiliary knife edge, between described first auxiliary knife edge and the first blade, all teeth are all formed between second auxiliary knife edge and the second blade, the back of tooth of all teeth is that arc-shaped is arranged.
As preferably, described first blade and the second blade are all formed with helicla flute, the excursion of spiral fluted helical angle is 24 °-36 °.
As preferably, described spiral fluted groove angle is smooth setting.
As preferably, described first blade and the second blade include axially open angle, and axially open angle is 15 ° of settings.
As preferably, the sword footpath of described blade part accounts for 65% of the diameter of shank section.
As preferably, the first blade and the second blade are all formed with relief angle, and relief angle is 17 ° of settings.
The utility model has following advantage compared to existing technology: the width of the dead point that the first blade of this rose cutter and the second blade are formed accounts for 1/4 of blade tread, when cutting, the intensity of point of penetration is higher like this, initial cutting stability can be ensured, and the first blade and the first auxiliary knife edge, the rear flank of all teeth formed between the second blade and the second auxiliary knife edge are that circular arc is arranged, can not cut be produced when cutting to the surface of workpiece like this, ensureing the smoothness of fluency and the surface of the work cut; And the first blade, the second blade are all formed with helicla flute, helicla flute is used for waste discharge bits and uses, and spiral fluted groove angle is smooth setting is to allow scrap more easily derive, and is not easy to produce BUE.

In figure: 1, shank section; 2, blade part; 21, the first blade; 22, the second blade; 23, the first auxiliary knife edge; 24, the second auxiliary knife edge; 25, helicla flute; 251, groove angle; 26, all teeth; 261, the back of tooth; 27, relief angle; 3, dead point.
Detailed description of the invention
Referring to figs. 1 through Fig. 4, the embodiment of a kind of rose cutter of the utility model is described further.
As shown in Figure 1, for should the structural representation of rose cutter, this rose cutter comprises shank section 1 and blade part 2, shank section 1 is one-body molded with blade part 2, formation first blade 21 and the second blade 22 is cut in shank section 1, first blade 21 and the second blade 22 are symmetrical arranged, as shown in Figure 2, and form dead point 3 at the head of blade part 2 between the first blade 21 and the second blade 22, the width of dead point 3 is 1/4 of the tread of the first blade 21 or the second blade 22, can ensure that larger cutting force is as cutting initial force like this when cutting, ensure that blade part 2 can not produce larger vibration when offering cutting, thus fluency when ensureing follow-up cutting, be not easy when cutting like this to produce BUE, and cut formation first auxiliary knife edge 23 and the second auxiliary knife edge 24 at the first blade 21 and the second blade 22 adjacent, first blade 21 and the first auxiliary knife edge 23, second blade 22 and the second auxiliary knife edge 24 all form all teeth 26, the back of tooth 261 of all teeth 26 is arranged in circular arc, as shown in Figure 4, can to avoid in prior art between the first blade 21 and the first auxiliary knife edge 23 like this, there are corner angle between second blade 22 and the second auxiliary knife edge 24 to make on workpiece, to leave impression when cutting, make when cutting, easily to cause the rough of cutting face cause the smoothness of workpiece difference and easily produce the situation vibrated and cause blade to fracture.
The excursion that first blade 21 and the equal spiral of the second blade 22 arrange the helical angle of formation is arranged on 24 °-36 °, such setting is to ensure that the sword footpath of blade part 2 is enough wide as far as possible both meeting and cut and require while, making blade part 2 have higher intensity and contact stress, making blade part 2 be not easy the generation of the phenomenon vibrated and fracture when cutting; Described first blade 21 and the second blade 22 are all formed with axially open angle, and axially open angle is 15 ° of settings, and such setting is also to can compare the intensity that labour-saving can ensure blade part 2 as far as possible when ensureing initial cutting simultaneously; The sword footpath of described blade part 2 accounts for 65% of the diameter of shank section 2, such setting changes the restriction in prior art, the sword footpath of blade part 2 being accounted for 50% of the diameter of shank section 1, increasing the bonding strength between blade part 2 and shank section 1, ensureing still can ensure that enough intensity makes ball cutter be not easy to fracture when cutting harder instrument; And the first blade 21 and the second blade 22 are all formed with relief angle 27, relief angle 27 is established in 17 °, the part contacted with shank section 1 at blade part 2 like this can have larger buffer index, the STRESS VARIATION run into when cutting can be made to decompose in one gradually linear course, thus make blade part 2 be not easy to produce vibration; And the smooth setting of groove angle 251 of helicla flute 25, the scrap produced when cutting like this is easier to be ejected in helicla flute 25, ensures fluency when cutting, and the surface meeting smoother of such workpiece, does not allow to produce BUE.
Below just achieving ball cutter, to have cutting hardness high, cuts the smooth smooth surface that can ensure workpiece, and easily derive the advantage of cutting scrap.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
