Technical Field
The utility model relates to a milling cutter technical field specifically is a T type cutter is cut futilely to aluminium with double tooth clearance end tooth.
Background
With the rapid development of high-speed machine tools, machining centers and machining technologies, the cutting power at a cutting speed is rapidly improved, so that the metal cutting amount in unit time is greatly increased, the cutting fluid consumption in the machining process of the machine tools is increased, the flow rate of the cutting fluid is sometimes 80-100L/min, but the cutting fluid is difficult to reach a cutting area actually during high-speed cutting, and the cutting fluid is difficult to cool, so that the development of the high-speed cutting technology promotes the research of a dry cutting technology, the dry cutting technology is a machining process which does not use or uses a small amount of cutting fluid, a clean and environment-friendly manufacturing process for controlling an environment pollution source is used as a novel green manufacturing technology, the environmental pollution is small, devices related to the cutting fluid can be omitted, a production system is simplified, the production cost of products can be greatly reduced, chips are formed cleanly and cleanly during passing, and the recovery and treatment are convenient, dry cutting uses T-shaped cutting tools in the summary of the machining technology.
However, there are some disadvantages in the conventional using process, such as:
the existing T-shaped machining cutters are all of single-tooth-gap structures, and the problem of cracking can be caused when high-speed large-allowance cutting is carried out in hole machining, so that the cutters cannot be normally used, and the service life of the cutters is shortened; meanwhile, when the existing single-tooth-space cutter is used for machining, scrap iron generated at the tooth space cannot be effectively discharged through the scrap discharging groove after being extruded and broken, and the problem of unsmooth scrap discharging is caused.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a T type cutter is cut futilely to double tooth clearance end tooth for aluminium to solve the problem that proposes in the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the knife comprises a knife handle, the one end fixed weld of handle of a knife has the connecting rod, the one end fixed weld that the handle of a knife was kept away from to the connecting rod has the cutter body, a plurality of margins have been seted up to the circumferential surface of cutter body, the one end that the connecting rod was kept away from to the cutter body is located and has seted up double tooth clearance end tooth chip groove between the margin.
Wherein the land is helical and the helix angle of the land is 37.5 degrees.
The connecting part of the connecting rod, the cutter body and the cutter handle is an inclined transition surface.
Wherein the land includes a forward edge and a rearward edge, and the forward edges are disposed flush with each other and the rearward edges are disposed flush with each other.
The cutter body is of a central axis symmetric structure, and grooves are polished by the cutter body through a D10 grinding wheel.
Compared with the prior art, the beneficial effects of the utility model are that:
form double tooth clearance end tooth chip groove through two liang of adjacent margins, not only can increase the chip removal volume of cutter in the course of working, and can utilize double tooth clearance end tooth chip groove to shunt the chip removal, effectually avoid can not effectively passing through chip groove exhaust problem after iron fillings are continuous extrudeed from a tooth clearance, double tooth clearance end tooth chip groove is more smooth and easy than single tooth clearance chip removal, thereby can carry out high-speed big allowance cutting, guarantee the normal use of this cutter, the dedicated 37.5 spiral angle of margin can effectually reduce the wearing and tearing of cutter in cutting process, prolong the life of this T type sword.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
In the figure: 1-a knife handle; 2-a connecting rod; 3-double tooth gap end tooth chip groove; 4-cutting edge; 5-knife body.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: including handle of a knife 1, the one end fixed weld of handle of a knife 1 has connecting rod 2, the one end fixed weld that handle of a knife 1 was kept away from to connecting rod 2 has cutter body 5, a plurality of margins 4 have been seted up to the circumferential surface of cutter body 5, cutter body 5 keeps away from the one end of connecting rod 2 and lies in and has seted up double gear space end tooth chip groove 3 between margin 4.
Wherein the blade zone 4 is in a spiral shape, and the spiral angle of the blade zone 4 is 37.5 degrees, so that the abrasion of the cutter in the cutting process is reduced.
The connecting part of the connecting rod 2, which is connected with the cutter body and the cutter handle 1, is an inclined transition surface, and the transition surface is helpful for chip removal during cutting and prevents the connecting rod 2 from influencing the cutting forming of the T-shaped groove.
The cutting edge 4 comprises a front cutting edge and a rear cutting edge, the front cutting edge is arranged in a flush manner, the rear cutting edge is arranged in a flush manner, and the flow direction of cutting scraps during cutting can be controlled to be discharged to the maximum extent.
