Description
Technical field
The utility model relates to a kind of slotting cutter of taking turns.
Background technology
The wheel slotting cutter is the special molding cutter of processing turbo rotor groove, distribute according to chipping allowance, generally it is designed to three cutters, be roughing milling cutter, half finish-milling cutter and finish-milling cutter, the chipping allowance maximum of half finish-milling cutter wherein, in order to alleviate the cutting resistance of cutter, improve cutter intensity, so each manufacturing firm all drops into very big technical force on the flute profile of half finish-milling cutter chip dividing groove and the degree of depth, its reason is that the shape and the depth of convolution of the waveform sword of chip dividing groove on the back knife face of cutter head is the principal element that influences cutter life; Half finish-milling cutter molded lines complex structure, during processing and manufacturing, half finish-milling cutter promptly should satisfy required precision, guarantee side set again, to guarantee that also the wavelength of waveform sword and the depth of convolution are even,, reach the purpose that improves cutter life to satisfy each tooth chipping allowance distributed uniform of cutter.The waveform sword of chip dividing groove is dovetail groove or circular arc dovetail groove on the back knife face of existing semi-precise milling cutter for concave groove cutter head, and when the waveform sword was dovetail groove, as shown in Figure 4, though processing easily, the heat radiation of cutting blade two cusps was slower, and intensity is relatively poor, and is easy to wear; When the waveform sword was the circular arc dovetail groove, as shown in Figure 5, cutting blade two cusp intensity were better, but cutter is in use, and bottom land easily produces stress and concentrates, and tipping takes place, simultaneously during the sharpening dovetail groove, and the easy threshing of emery wheel two cusps.
The utility model content
The purpose of this utility model is for the waveform sword design of chip dividing groove on the back knife face that solves existing semi-precise milling cutter for concave groove cutter head is unreasonable, causes taking turns slotting cutter in use, and problem easy to wear, that tipping takes place provides a kind of circular arc waveform sword semi-precise milling cutter for concave groove.
The utility model is made up of handle of a knife, shoulder and cutter head, handle of a knife, shoulder and cutter head are made one successively, the appearance of cutter head is a bullet, the outer surface of cutter head is provided with the spiral shell land, the junction of cutter head and shoulder is provided with at least three chip pockets to the end of cutter head, and the spiral shell land is provided with the waveform sword along its length, described waveform sword chip dividing groove be shaped as circular arc, the groove depth of waveform sword is 0.2mm～0.3mm, and the chip dividing groove width of waveform sword is 1mm～2mm.
The utility model has the advantages that: one, the utility model is a circular arc with the shaped design of waveform sword chip dividing groove, has avoided the wheel slotting cutter in use to produce tipping, has reduced the Tool in Cutting resistance, increases the cutter wearability.Two, the circular arc chip dividing groove makes that the utility model chip removal is smooth and easy, and heat radiation when helping Tool in Cutting, vibration be little, be difficult for forging a knife, and improves Tool in Cutting efficient, strengthens cutter intensity, improves cutter life, reduces tool expense.
Description of drawings
Fig. 1 is an overall structure front view of the present utility model, Fig. 2 is the I partial enlarged drawing of Fig. 1, Fig. 3 is the main TV structure figure of circular arc waveform sword 3-1-1 chip dividing groove, Fig. 4 is that the waveform sword of chip dividing groove is the main TV structure figure of dovetail groove on the back knife face of existing semi-precise milling cutter for concave groove cutter head, and Fig. 5 is that the waveform sword of chip dividing groove is the main TV structure figure of circular arc dovetail groove on the back knife face of existing semi-precise milling cutter for concave groove cutter head.
The specific embodiment
The specific embodiment one: present embodiment is described in conjunction with Fig. 1～Fig. 3, present embodiment is by handle of a knife 1, shoulder 2 and cutter head 3 are formed, handle of a knife 1, shoulder 2 and cutter head 3 are made one successively, the appearance of cutter head 3 is a bullet, the outer surface of cutter head 3 is provided with spiral shell land 3-1, the junction of cutter head 3 and shoulder 2 to the end of cutter head 3 is provided with at least three chip pocket 3-2, spiral shell land 3-1 is provided with waveform sword 3-1-1 along its length, waveform sword 3-1-1 chip dividing groove be shaped as circular arc, the groove depth h of waveform sword 3-1-1 is 0.2mm～0.3mm, the chip dividing groove width T of waveform sword 3-1-1 is that the depth of 1mm～2mm. chip dividing groove directly influences the number of times that half finish-milling cutter repeats sharpening, chip dividing groove is too dark, can reduce the intensity of half finish-milling blade part, chip dividing groove is too shallow, the number of times that half finish-milling cutter repeats sharpening will reduce, cause waste. show through analysis of experiments, the groove depth h of chip dividing groove is chosen between 0.2mm～0.3mm, make that the intensity of half finish-milling blade part is best, the number of times that half finish-milling cutter repeats sharpening reconditioning 4-6 time under the normal wear situation, thereby having improved the service life of cutter. the width of chip dividing groove also is to influence one of the half finish-milling cutter cutting force and the factor in service life. half finish-milling cutter chip dividing groove is too wide, effectively spiral shell land 3-1 is just narrow, this moment, heat in metal cutting was concentrated on the spiral shell land 3-1, can't cool off rapidly, reduce the service life of half finish-milling cutter, double finish-milling cutter divides the complementary design of bits also to bring influence simultaneously; And chip dividing groove is too narrow, effective spiral shell land 3-1 is broadened, though played bifurcating chip action this moment, the contact area of spiral shell land 3-1 and workpiece is excessive, can produce very big frictional force, very big cutting force and very high heat in metal cutting, to still having a significant impact in service life of cutter; Experimental study shows, half finish-milling cutter axially, when the chip dividing groove width T on each spiral shell land 3-1 evenly distributes, both can play branch bits complementation, reduced the cutting force of each tooth again, cutting force is evenly distributed. when chip dividing groove width T is 1mm～2mm, make the cutting force minimum of half finish-milling cutter, heat in metal cutting also minimum. the utility model is in actual cut processing, the molded lines surplus is (the molded lines surplus is in 0.1mm) evenly, and stock-removing efficiency and cutter life all improve greatly.
The specific embodiment two: in conjunction with Fig. 3 present embodiment is described, the groove depth h of the waveform sword 3-1-1 of present embodiment is 0.25mm.The groove depth h of chip dividing groove is chosen in 0.25mm, makes that the intensity of half finish-milling blade part is best, the number of times that half finish-milling cutter repeats sharpening reconditioning 4-6 time under the normal wear situation, thereby the service life of having improved cutter.Other composition and connection are identical with the specific embodiment one.
The specific embodiment three: in conjunction with Fig. 2 present embodiment is described, the chip dividing groove width T of the waveform sword 3-1-1 of present embodiment is 1.5mm.When chip dividing groove width T is 1.5mm, make that the cutting force minimum, heat in metal cutting of half finish-milling cutter are also minimum.Other composition and connection are identical with the specific embodiment one.
The utility model is in actual cut processing, and the molded lines surplus is (the molded lines surplus is in 0.1mm) evenly, and stock-removing efficiency and cutter life all improve greatly.
