Abstract
The utility model relates to a circular jacking cutter, mainly used as a cutter for processing any metal whose strength and hardness are equal to or below 45[#] steel or annular nonmetal or parts with holes. With cemented carbide and high speed steel as the material and the shape and angle of the cutter head, the utility model can carry out trepanning coring for annular parts with aperture of over 35 millimetres and parts with holes. Trepanning feeding speed can reach 1.25 millimetres / second with processing efficiency increased by 3 to 5 times compared with the original processing method, materials saved by more than 15% and consumption of electric power saved by 30% to 70%. The machine tool wear and processing noise are reduced.
Description
The utility model drum type brake trepanning tool is the cutter that a kind of mechanical cold working jacking is got core, is specially adapted to process any metal or nonmetal ring-type class and part with holes that intensity and hardness are equivalent to or are lower than the 45# steel.
" metal cutting tool " book of Higher Education Publishing House's printing in August nineteen ninety, in the 56th page, announced that the mechanical cold process of a kind of usefulness carries out the cutter that jacking is got core processing, but adopted it only to be applicable to the aperture at the product more than 60 millimeters, the processing joint-cutting is greater than 16 millimeters.In addition, for processing the aperture at the product below 60 millimeters, usually adopt the method for centre-drilling hole, and required size often can't once be got in the processing aperture when the part more than 30 millimeters, must get out centre bore with the less drill bit of diameter earlier, use bigger drill bit counterboring again, so not only waste the hole core material, and the lathe load is heavy, wearing and tearing are terrible, the processing noise is big, and production efficiency is also low.
The purpose of this utility model: for overcoming the shortcoming of above-mentioned prior art, design a kind of processing aperture that is applicable to and get the cutter of core at the jacking more than 35 millimeters, and the processing joint-cutting is less than 4 millimeters, only once just can directly be set to required size, the lathe load greatly alleviates, wearing and tearing and processing noise reduce more, conserve bore core material not only, and improved production efficiency.
The technology that the utility model adopted is: the drum type brake trepanning tool has cutter head, cutter tube and handle of a knife.
Cutter head adopts carbide alloy or high-speed steel to make material, be welded on the cutter tube, its number can be two or more, and the available steel of cutter tube are made, the cutting edge of cutter head divides main cutting edge and front cutting edge, and the number of degrees of the tool cutting edge angle of Xing Chenging are between 5 ° to 30 ° thus; The number of degrees of auxiliary angle are between 0 ° to 15 °, and the width of front cutting edge is generally between 0.2 millimeter to 1.5 millimeters; The cutting anterior angle is between 10 ° to 30 °; Back angle also has chip area between the cutter head simultaneously between 5 ° to 15 °.Handle of a knife can have different shapes, and its size is more changeable than cutter tube.
Effect of the present utility model: owing to adopt above technology, can making jacking get core processing, the aperture is minimum drops to 35 millimeters, joint-cutting is less than 4 millimeters, the jacking feed velocity can reach 1.25 mm/second, and working (machining) efficiency can be brought up to 3 to 5 times of former processing method, saves material more than 15%, conservation of power consumes about 30～70%, lathe load, wearing and tearing reduce, and increase service life, and the processing noise also greatly reduces.This cutter is applicable to that intensity and hardness are equivalent to or are lower than the processing of any metal or the nonmetallic materials ring-type or the porose part of 45# steel.
Accompanying drawing is the structural representation of the utility model drum type brake trepanning tool.
Illustrate with most preferred embodiment shown in the accompanying drawing: R is a cutter head, it is the cutwork part of trepanning tool, be welded on the cutter tube T as material with YW303 type carbide chip, cutter tube T makes material with the 45# steel, and 48.5 millimeters of its external diameter φ, B are handle of a knife, P is a chip area, cutter head R adopts three, and chip area also has three, φ
zBe 10 ° of tool cutting edge angles, φ
fBe 5 ° of auxiliary angles, γ is 25 ° of cutting anterior angles, and α is 8 ° of back angles, γ
zBe main cutting edge, r
fBe front cutting edge, front cutting edge r
fLength be 0.4mm, S is the chip removal groove width, H is the chip removal groove depth, groove depth 35mm.Groove width 18mm.
