Abstract
The utility model belongs to the technical field of industrial cutters and discloses a quick chip removal end mill. The quick chip removal end mill comprises a mill handle and a mill head, wherein a chip groove is formed in the mill head; a spiral bulged ridge extending to the front end part of the mill head is formed in the middle of the chip groove; a main cutting edge is arranged on the bulged ridge; a chip pocket is arranged on the mill handle and communicated with the chip groove; and a strip-type bulge is arranged at the bottom of the chip groove and extends from the front end of the chip groove to the rear end of the chip groove along the chip groove. According to the end mill, the spiral chip discharge groove is formed in the mill head and can quickly remove chips caused by milling during workpiece machining; the main cutting edge on the bulged ridge can prevent burrs from being generated on a workpiece during the machining, so that the quality of the machined workpiece is improved; the end mill is simple in structure, low in machining cost, abrasion-resistant and wide in application scope; and the strip-type bulge can increase the drilling speed.
Description
Technical field
The utility model belongs to industrial cutting-tool engineering field, is specifically related to a kind of quick chip removal slotting cutter.
Background technology
Quick chip removal slotting cutter, be machined grooves, step and various mutually perpendicular plane, a kind of shank tools of using of the deep trouth on the box parts of machined steel and cast iron particularly, the quick chip removal slotting cutter of standard is divided into two kinds of bastard and serrations, often will process some mould or workpiece now, in process, have the following disadvantages: 1, the cutting edge of cutter is not sharp, material bits can not very fast discharge, influence next step continuation of processing work and processes; 2, in processing, be easy to generate a lot of burrs on the workpiece, influence the quality of processing work; 3, cutter is easy to wear, and service life is short.
The utility model content
It is low, wear-resistant and be beneficial to the quick chip removal slotting cutter of quick chip removal that the purpose of this utility model provides a kind of processing cost.
The utility model is achieved in that
A kind of quick chip removal slotting cutter comprises handle of a knife and cutter head, and handle of a knife and cutter head are integral structure, and cutter head is provided with chip area; Form ridge spiral helicine and that extend to the cutter head leading section between the chip area, ridge is provided with main cutting edge, the cutter head leading section is provided with front cutting edge, the bottom land of described chip area is provided with the bar shaped projection, this bar shaped projection extends to the rear end of this chip area always along the chip area trend from the chip area front end, also be provided with chip pocket on the described handle of a knife, described chip pocket is connected with chip area.
The utility model outstanding advantage compared to existing technology is: the utility model cutter head is provided with spiral chip area, and material bits that can milling stays in the processing work process are discharged fast; In the process, the main cutting edge on the ridge can prevent from producing burr on the workpiece, has improved the quality of processing work; The utility model is simple in structure, and processing cost is low, and is wear-resistant, and applied range.Because the bottom land at chip area is provided with the bar shaped projection that extends to the chip area rear end from the front end of this chip area, when cutter head in boring during chip removal, its bar shaped projection can play the effect at mediation bits end, make the chip area of cutter head be difficult for being squeezed stifled by the bits end, improved the speed of boring, cutter head can not fractureed because torsion is excessive easily yet.Simultaneously at handle of a knife chip pocket is set, allows to allow the interior cutter bits of chip area enter in the chip pocket, amass in perforate import department stuck cutter thereby avoid the cutter bits to discharge.
Description of drawings
Fig. 1 is front view of the present utility model.
The specific embodiment
With specific embodiment the utility model is further described below, referring to Fig. 1:
A kind of quick chip removal slotting cutter comprises handle of a knife 1 and cutter head 2, and handle of a knife 1 and cutter head 2 are integral structure, and such structure is simpler, low cost of manufacture; Cutter head 2 is provided with chip area 22, makes that the material bits in the cutting process can be discharged fast along chip area 22, is unlikely to influence next step continuation of workpiece and processes; Form ridge 21 spiral helicine and that extend to cutter head 2 leading sections between the chip area 22, two surface intersections on the ridge 21 form main cutting edges 3, and cutter head 2 leading sections are provided with front cutting edge 4.The bottom land of described chip area 22 is provided with bar shaped projection 5, and this bar shaped projection 5 extends to the rear end of this chip area 22 always along chip area 22 trends from chip area 22 front ends.Also be provided with chip pocket 6 on the described handle of a knife 1, described chip pocket 6 is connected with chip area 22.
Described handle of a knife 1 is cylinder or bullet.
The middle part outer surface of described handle of a knife 1 is provided with an annular slot 11, makes can not cause quick chip removal slotting cutter loosening dropping in process by more firm grip handle of a knife 1 of cutter holder.
The front cutting edge 4 of described cutter head 2 leading sections has 3-8.
Above-described embodiment only is one of preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; so: all equivalences of doing according to shape of the present utility model, structure, principle change, and all should be covered by within the protection domain of the present utility model.
