Description

Cutting tool

Technical field

The present invention relates to process equipment, particularly be used to cut the cutting of native stone material or the cutter of fluting.

Background technology

Cutting grooving tool of the prior art generally all is the vertial knife edge form, and the cooling of not only ventilating of this straight-blade type cutter is bad, and causes ash bits to advance to fly everywhere, pollutes surrounding environment.In addition, this straight-blade type cutter causes the phenomenon of tipping to take place also because the sword body is not enough to the cutting edge support degree easily, has influenced the service life of cutter.

Summary of the invention

The present invention provides a kind of cutting tool; The method that adopts the sword body to be provided with along cutter sheet outer vortex direction; Strengthening the sword body supports cutting edge; Simultaneously, form the passage of being convenient to wind-guiding and dust lead between adjacent two blades, solve cutter self cooling capacity deficiency and contaminated environment and short technical problem in self service life in the prior art.

The present invention solves the problems of the technologies described above the cutting tool that provides to comprise the wafer-type tool bodies with centre bore; Be fixed in a plurality of independently blades of this tool bodies outer rim; Said each blade is along the hand of helix setting of tool bodies, and this helix is launched to outer rim by the centre bore of wafer-type tool bodies.

Further improvement of the present invention is: the tread of said each blade is greater than the thickness of tool bodies, and both sides protrude in the side of tool bodies, the groove of formation depression between adjacent two blades.

Of the present invention further the improvement again is: said each blade is by cutting edge curved shape at the bottom of sword, and the cutting edge of said each blade overlaps with the RADIAL of this position of tool bodies, and said groove is horn-like by cutting edge direction at the bottom of sword of blade.

Of the present invention further the improvement is: said tool bodies comprises two independences and coaxial cutter sheet; Be folded with the planing tool of disc type between these two cutter sheets; Said two cutter sheets are coaxial and be fixed as one with planing tool, and the diameter of said planing tool is less than the diameter of any cutter sheet.Said planing tool comprises the cutter blade of disc type and along the hand of helix of cutter blade a plurality of independently planing tool swords is set; This helix is launched to outer rim by the centre bore of cutter blade; Be fixed as one through welding between said two cutter sheets and the planing tool; Be fixed as one through securing member between perhaps said two cutter sheets and the planing tool, be fixed as one through rivet between said more specifically two cutter sheets and the planing tool.

The present invention adopts above-mentioned technical scheme; The characteristics of make that this novel cutting tool has that self induced air cooling, sword body are big to the knife edge part support degree, the scrap after the cutting not flying upward; And; This novel cutting tool fluting is convenient, fast, also is particularly suitable for double dynamical cutting tool use or the like advantage, has good and economic and practicality.

The specific embodiment

Specify specific embodiment of the present invention in conjunction with above-mentioned accompanying drawing.

By knowing among Fig. 1 to Fig. 4; This cutting tool comprises the wafer-type tool bodies 10 with centre bore 11; Be fixed in a plurality of independently blades 20 of this tool bodies outer rim; Said each blade 20 is along the hand of helix setting of tool bodies 10, and this helix is launched to outer rim by the centre bore 11 of wafer-type tool bodies 10.Blade 20 when cutting operation, becomes strong support to knife-edge along the hand of helix setting of tool bodies 10 among the present invention, guarantee blade when cutting not can owing to stressed excessively and tipping.

By knowing among Fig. 1 and Fig. 2, the tread of said each blade 20 is greater than the thickness of tool bodies 10, and both sides protrude in the side of tool bodies 10, the groove 12 of formation depression between adjacent two blades 20.Formed groove 12 between adjacent two blades among the present invention; When blade does not get into cut state; Blade imports the middle part of blade with the air of outside along groove, not only knife edge part is formed air-cooled effect, also the middle part of cutter has been formed certain cooling effect simultaneously.When cutter got into cut state, this groove can also be derived the scrap under the cutting along groove, and scrap is derived the scrap gatherer that the back gets into cutting tool along groove, is convenient to protect surrounding environment.

By knowing among Fig. 2, said each blade 20 is by cutting edge 21 22 curved shapes at the bottom of sword, and the cutting edge 21 of said each blade 20 overlaps with the RADIAL of tool bodies 10 these positions, and said groove 12 is horn-like by cutting edge 21 22 directions at the bottom of sword of blade 20.Among the present invention blade 20 being designed to shaped form, is the derivation for the ease of scrap on the one hand, and scrap is reclaimed by the scrap gatherer along the angle of groove smoothly; Simultaneously, in double dynamical balanced type cutting grooving tool, use this cutter more favourable, two symmetrically arranged cutters; Its blade forms the blade of a serpentine; Not only in the cutting process, strength can reach good balance, and; Because it has the curve shape of rounding off, the support of cutting edge roundness has also been reached fare-you-well.

By knowing among Fig. 3 to Fig. 6; Said tool bodies 10 comprises two independences and coaxial cutter sheet 13; Be folded with the planing tool 14 of disc type between these two cutter sheets 13, said two cutter sheets 13 and planing tool 14 are coaxial and be fixed as one, and the diameter of said planing tool 14 is less than the diameter of any cutter sheet 13.Said planing tool 14 comprises the cutter blade 141 of disc type and along the hand of helix of cutter blade 141 a plurality of independently planing tool swords 142 is set that this helix is launched to outer rim by the centre bore of cutter blade 141.The cutting tool of this scheme of the present invention is the cutter with fluting function, and after the object cut-out of two cutter sheets 13 with the groove both sides, the planing tool in the middle of utilizing digs the entity part in the middle of two otch; Because both sides cut off; Support force around intermediate entities partly receives weakens greatly, and planing tool digs above-mentioned entity part will become very easy, the complete so unnecessary manual work plane cutter that carries out again; Lot of manpower and material resources has been saved in the disposable completion of fluting work.

Be fixed as one through welding between said two cutter sheets 13 and the planing tool 14; Be fixed as one through securing member between perhaps said two cutter sheets 13 and the planing tool 14, scheme is to be fixed as one through rivet between said two cutter sheets 13 and the planing tool 14 more specifically.Planing tool part can arbitrarily be changed in the middle of among the present invention, the width of fluting as required, and folder is established the planing tool of different-thickness, can adopt welding fixing for the planing tool of frequent use, then can fix through securing member at any time for the planing tool that does not often use.

Above content is to combine concrete preferred implementation to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
