Abstract
The utility model discloses a reamer for a knuckle arm to ream, which comprises a reamer rod and a reamer head arranged at the front end of the reamer rod. The reamer head is provided with blade which is provided with a chip groove; the chip groove is arranged on the periphery of the blade end surface; the blade is obliquely arranged on the reamer head; the angle between an upper angle and a lower angle of the blade is 8-12 degrees; the inclined angle from the reamer head with the blade which is obliquely arranged on the reamer head to the reamer tail is 2-5 degrees; and the width of the groove opening of the chip groove is 3-6mm. By changing the reamer head structure of the reamer, the utility model effectively solves the problems that the reamer of the current knuckle arm in the market has poor surface roughness, low production efficiency and the like in the process of processing workpieces, simultaneously, has longer service life, can effectively reduce the processing cost, and the like.
Description
Technical field
The utility model relates to a kind of knuckle arm machining tool, relates in particular to a kind of knuckle arm fraising reamer.
Background technology
At present be used to process the reamer of knuckle arm on the market, in use, phenomenons such as cracking of cutter, cutting edge collapse cutter, tool wear is fast, and the life-span is short occur, cause that the workpiece surface roughness processed is poor, production efficiency is low, problems such as processing cost height through regular meeting.
The utility model content
The purpose of this utility model is in order to overcome technological deficiency recited above, a kind of knuckle arm fraising reamer to be provided.
In order to solve technical problem recited above, the utility model is taked following technical scheme:
The utility model provides a kind of knuckle arm fraising reamer, include knife bar and the cutter head that is arranged on the knife bar front end, cutter head is provided with blade, on cutter head, offer chip area, described chip area is opened in the periphery of blade end face, described edge tilted is arranged on the cutter head, and the angle of inferior horn is 8～12 degree on the blade.
Described cutter head is a conical head, and blade and cutter head are designed to one, and for also improving the service life of cutter reamer, cutter hub adopts cutter head and the blade of being made by high-speed steel, and cutter head is provided with 3～6 blades.
High-speed steel has another name called air hardening steel or high-speed steel, even cooling off in air when being quenching, the meaning also can harden, and very sharp.It is a kind of steel alloy of complicated component, contains carbide formers such as tungsten, molybdenum, chromium, vanadium, and the alloying element total amount reaches about 10～25%.It produces in high-speed cutting, and (about 500 ℃) still can keep high hardness under the high enthusiasm condition, and HRC can be more than 60, the topmost characteristic of high-speed steel---red hardness that Here it is.And carbon tool steel is after quenching and lonneal, though very high hardness is at room temperature arranged, but when temperature is higher than 200 ℃, hardness just sharply descends, dropped to the degree similar 500 ℃ of hardness to annealed condition, completely lost the ability of cutting metal, this has just limited carbon tool steel and has made cutting element usefulness.And high-speed steel has remedied the fatal shortcoming of carbon tool steel because red hardness is good, can be used for making cutting element.
As a kind of preferred version, the described sword head that is obliquely installed the blade on cutter head is 2～5 degree to the inclination angle of sword tail.
The width of rebate of described chip area is 3-6mm.
Problems such as the utility model passes through to change the cutter head structure of reamer, and the surface roughness that the present knuckle arm reamer on the market of effective solution exists in the processing work process is poor, production efficiency is low, service life while is longer, can effectively cut down finished cost etc.
Below with reference to the drawings and specific embodiments, the utility model is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is the main TV structure schematic cross-section of knuckle arm fraising of the present utility model with reamer.
Fig. 2 is a side view of the present utility model.
Among the figure: 1. knife bar, 2. cutter head, 3. blade, 4. chip area, 31. sword heads, 32. sword tails.
The specific embodiment
See also Fig. 1 and Fig. 2, as shown in the figure, the knuckle arm fraising includes knife bar 1 with reamer and is arranged on the cutter head 2 of knife bar 1 front end; Cutter head 2 is a conical head; Cutter head 2 is provided with 4 blades, and blade 3 is obliquely installed on cutter head 2, and the sword head 31 of blade 3 is 2～5 degree to the inclination alpha of sword tail 32, and the angle beta of inferior horn is 8～12 degree on the blade 3; Blade 3 is arranged on the cutter head 2 by the mode of welding, and perhaps blade 3 is designed to one with cutter head 2; Blade 3 and cutter head 2 all adopt high-speed steel to make; Offer chip area 4 on cutter head 2, described chip area 4 is opened in the periphery of blade 3 end faces, and the width of rebate of chip area 4 is 3-6mm.
