Abstract
The utility model discloses an anterior angle inclined furrow wheel trough semi-fine milling cutter. The adjacent tooth chip separation troughs are axially staggered in a Christmas tree shape. A plurality of rear foot chip separation troughs is stagger-arranged on the tooth form surface of the edge of the milling cutter with a taper shank. The anterior angle inclined furrow wheel trough semi-fine milling cutter of the utility model has the advantages of that the damping vibration is good and the ability to reduce buffet is enhanced, the cutting quantity is raised, and the efficiency can be raised by 4 to 5 times.
Description
Technical field
The utility model relates to a kind of positive rake angle valley semi-precise milling cutter for concave groove.
Background technology
Along with China's entry into the World Trade Organization, all trades and professions and the world of China integrate with at present.Constantly introduce external new product.Particularly aspect power industry, along with the sustainable growth electric industry imbalance between supply and demand of China's economy becomes increasingly conspicuous, this has just hindered Chinese economic development.In order to solve this contradiction, the generating set product of developed countries such as west will be introduced and digest to China's steam-turbine power plant.Past, the wheel slotting cutter of China's steam turbine industry processing impeller groove is introduced from US Westinghouse company, half finish-milling cutter is the rod-type milling cutter of straight flute, 0 ° of anterior angle, this Christmas, tree-like milling cutter was in stable cutting, aspects such as cutting ability and efficient and durability all can not satisfy the constantly needs of development of steam turbine industry, the ability that this half finish-milling cutter suppresses flutter is also lower, will produce vibration when feed is big, can not normally cut.So every processing just needs the tool changing reconditioning for 1.0 meters, working (machining) efficiency is low.Often tool changing is wasted time and energy, and influence is produced.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, and a kind of operating efficiency, dimensional accuracy, the higher positive rake angle valley semi-precise milling cutter for concave groove of suface processing quality are provided.
In order to achieve the above object, the technical solution adopted in the utility model is: adjacent two tooth chip dividing grooves are tree-shaped Christmas of axially staggering, and have the be staggered chip dividing groove of the rear foot of taper-shank cutter blade toothed surfaces.
The utility model has the advantages that:
1, vibration damping is good: because blade is discontinuous, cut workpiece easily, again because of the increase of thickness of cutting, reduce the sliding phenomenon of blade on surface of the work, thereby improved the ability that suppresses flutter;
2, improve cutting data: the oblique angle of lip surface is 3～5 °, realizes inclined cutting, reduces cutting deformation and energy consumption.Toothed surfaces is staggered shovels out chip dividing groove, is axially staggering in the chip dividing groove position.Can reduce chip deformation, thereby reduce cutting force and heat in metal cutting, also help chip removal, increase substantially feed engagement;
3, owing to open the rigidity that chip dividing groove increases the chip curling direction, make curly course absorb more energy, chip breaking is easy, and chip removal is smooth and easy, and cutting edge length is short, and cutter is difficult for producing vibration, and chip volume is little, and chip removal is easy, and it is convenient to handle;
4, stock-removing efficiency height: because the damping property of cutter is good, the durability height allows to adopt big feed, and full depth is so production efficiency can improve 4～5 times.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that the A of Fig. 1 is to schematic diagram;
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Tu as can be known, the utility model is that adjacent two tooth chip dividing grooves are tree-shaped Christmas of axially staggering, and has the be staggered chip dividing groove 4 of the rear foot of taper shank 1 milling cutter blade 3 toothed surfaces.
The oblique angle of milling cutter lip surface is 3～5 °, and the anterior angle of holding about tool-tooth profile is 10 °, and the rear foot is an Archimedes spiral, and shank end face 2 is 0.127-0.254 with taper shank gauge gap, and shank end face 2 is ± 0.0127 with the range deviation of blade metering end.
The utility model is a kind of positive rake angle valley, can realize the tree-like semi-precise milling cutter for concave groove on Christmas of inclined cutting, and lip surface is 3～5 ° of valleys, and anterior angle is 10 °.And toothed surfaces is staggered shovels out chip dividing groove, is axially staggering in the chip dividing groove position.Can reduce chip deformation, thereby reduce cutting force and heat in metal cutting, also help chip removal.Increase substantially feed engagement.
The utility model is very tight by the shank required precision of Fig. 1, Fig. 2 milling cutter, can be installed in to decide the dress milling cutter on the import special purpose machine tool, and shank is No. 9 taperings of Blang Sharp, and the gap of the end face of milling cutter and gauge end face is 0.127～0.254.
The shank end face, the distance dependent of the metering diameter of this end face and blade, its deviation is ± 0.0127.
The blade profile of tooth is that Christmas is tree-like, is 0.2mm with respect to the profile of tooth allowance of finish-milling cutter, and the profile of tooth tolerance is 0.03.The run-out tolerance of all diameters is 0.0127 on total length.
The crucial blade of version of the present utility model, promptly the anterior angle at the big small end of milling cutter is that 10 ° of lip surface oblique angles are 3 °～5 °, interlocks on the back of tooth and shovels out chip dividing groove, axially staggering in the chip dividing groove position.
Claims (2)
