Abstract
The invention relates to a novel rigid cutter bar which comprises a cylindrical body and a curved groove. The cutter bar is characterized in that the cylindrical body (1) is provided with the curved groove (2) in the section. The novel rigid cutter bar has the advantages that the sectional shape of the cylindrical cutter bar is modified, and the cutter bar is resistant to vibration, bending deformation and torsional deformation, high in rigidity, simple in structure, easy to manufacture, economic and practical, good in reliability, energy saving, consumption reducing, and the like while the cutter bar is small in diameter.
Description
Technical field
The invention belongs to rigid bar, especially a kind of cutter and cutter bar for machine-building.
Background technology
Normal machining small, deep hole in machine-building, the limitation of conventional conventional knife knife bar material, minor diameter arbor stiffness is poor, is difficult to the little roughness value reaching designing requirement, high-precision form and position tolerance.Common have following several situation: 1, process little and dark blind hole, due to processing blind hole chip removal difficulty, causes chip to scratch to hole wall on the one hand, cause hole wall roughness value to increase; Cause chip to squeeze out existing cutter relieving phenomenon to knife bar on the other hand, cause dimensional discrepancy, form and position tolerance to increase; 2, the impact of cutting force, the passive generation vibrations of knife bar, vibroseis is that knife bar self stability difference occurs that flexural deformation causes, and then produces toolsmith's process system vibration vibrations, and machined surface occurs that chatter mark affects surface roughness; 3, similarly, because toolsmith's process system is subject to the impact of cutting force, the passive generation torsional deflection of knife bar, this torsional deflection to pivot vibrations because the impact of knife bar self stability produces knife bar, has influence on roughness and the form and position tolerance of finished surface.On several situations of mentioning not degree considerable influence is produced to cutter life.
During reality is produced, machine-building Hardmetal materials substitutes conventional knife bar metal material, as wolfram steel.Because tungsten steel alloy is expensive, increase production cost with wolfram steel material substitution conventional material and rise, and wolfram steel material knife bar does not have large improvement in solution knife bar flexural deformation and torsional deflection.
Summary of the invention
The object of the invention is to overcome above-mentioned machine-building Problems existing by novel designs, provide one to have antidetonation, counter-bending distortion, anti-torsion distortion, rigidity is larger, structure is simple, easily manufactures, economical and practical, good reliability, the rigidity knife bar of the advantage such as energy-saving and cost-reducing.
Technical solution of the present invention is such, and a kind of novel rigidity knife bar, comprises cylinder and curved groove, it is characterized in that described cylinder is provided with curved groove; Described curved groove establishes curved configuration at cylinder section; Described curved groove can be arranged by parallel knife bar axis, can around knife bar axis rotary setting.
The present invention can manufacture as modularization knife bar, is combined can gives full play to advantage of the present invention with existing lock dentition formula modularization cutter head.
Distinguishing feature of the present invention is by transformation cylinder knife bar cross sectional shape, makes cutter and cutter bar in small diameter situation, has antidetonation, counter-bending distortion, anti-torsion distortion, rigidity is comparatively large, and structure is simple, easily manufactures, economical and practical, good reliability, the advantage such as energy-saving and cost-reducing.
accompanying drawing illustrates:
Fig. 1 is overall structure 3-D view of the present invention,
Fig. 2 is overall structure cross sectional view of the present invention,
Fig. 3 is overall structure three-dimensional view axis figure of the present invention,
In Fig. 1 ~ Fig. 3, cylinder (1), curved groove (2), curvilinear shaped slots (3), axis (4).
detailed description of the invention:
Most preferred embodiment of the present invention is such, and shown in Fig. 3, a kind of novel rigidity knife bar, comprises cylinder, curved groove, and wherein, described cylinder 1 is provided with curved groove 2; Described curved groove 2 establishes curvilinear shaped slots 3 at cylinder section; Described curved groove 2 can be arranged by parallel knife bar axis 4, can around knife bar axis rotary setting.
Strengthen the embodiment of arbor stiffness: by transformation cylinder circular section shape, in cylinder 1 cross section, curvilinear shaped slots 3 is set, make the circular cross-section of cylinder 1 form stable structure, curvilinear shaped slots 3 develops into curved groove 2 along axis 4, to meet the counter-bending deformation design requirement of knife bar.
Strengthen the embodiment of knife bar stability: by transformation cylinder 1 circular section shape, in cylinder 1 cross section, curvilinear shaped slots 3 is set, make the circular cross-section of cylinder 1 form stable structure, curvilinear shaped slots 3 develops into curved groove 2 along axis 4, to meet knife bar anti-torsion deformation design requirement.
Claims (2)
1. a novel rigidity knife bar, comprises cylinder, curved groove, it is characterized in that, described cylinder (1) is provided with curved groove (2), and described curved groove (2) is provided with curvilinear shaped slots (3) in cylinder (1) cross section.
2. a kind of novel rigidity knife bar as claimed in claim 1, is characterized in that, described curved groove (2) can parallel knife bar axis (4) be arranged, can around knife bar axis (4) rotary setting.
