Abstract
The utility model discloses a big blade obliquity strong cutting tool for strongly cutting, pertaining to a metal cutting tool. The upper plane of a knife blade groove of an elbow part of an L-shaped cutting tool body being opposite to the plane of a long handle part inclines 35 degrees downwards, the big blade obliquity knife blade is arranged in the knife blade groove that has the same shape as the big blade obliquity knife blade, a chip breaking block is stacked and mounted on the knife blade and compacted in the knife blade groove by a bolt. The utility model is characterized in that the main cutting tool is designed as a 35-degree big blade obliquity that has an R circular chamfer angle, which greatly reduces the cutting resistance but increases shock resistance of the cutting tools; furthermore, a knife blade can be used repeatedly for four times, thus the improving cutting speed and 2-3 times of the service life with high production efficiency; the chip breaking block is used for controlling the flowing direction of scrap iron, thereby guaranteeing the safety of the operators. The utility model can be widely applicable for vertical and horizontal large and medium-sized lathe.
Description
Technical field
The utility model belongs to metal cutting tool, and workpiece that particularly can finished surface is irregular, hardness is high, and shock resistance is good under the interrupted cut state carries out high-rate cutting and the powerful machine truck of a kind of big cutting edge inclination cutter of fragile blade not.
Background technology
In the turnery of machining, run into during roughing that surface of the work is irregular, flash, sand holes, material is impure, inhomogeneous, electricity vapor phase soldering access node structure processing rear surface hardness height, under the interrupted cut state, big to the cutter impulsive force, common lathe tool cutter very easily damages.
Summary of the invention
The purpose of this utility model provides the powerful machine truck of a kind of big cutting edge inclination cutter, it is characterized in that: on the elbow part of L type machine swaging clamp body 7, leave the insert groove 6 that blade 5 is installed, pad 3, chip breaking piece 4 and blade 5 firmly are pressed on the fixing hole of machine swaging clamp body 7 by hex screw 2.
Described blade is a square, and on a slice blade, it is the same to have four cutting-tool angles, the main cutting edge of homomorphosis.
The tool cutting edge angle of described blade is 45 °, and auxiliary angle is that 15 °, primary clearance are 6 °, and the main cutting edge cutting edge inclination is 35 °, and the anterior angle at main cutting edge position is-3 °～-5 °, and the cutting edge inclination anterior angle at point of a knife position is 0 °, and nose angle is 120 °.
The chamfered of circular arc also will be carried out in the point of a knife position of described main cutting edge, and the negative chamfered edge processing about-10 ° * 0.3mm is carried out at main cutting edge and point of a knife position.
The last plane of described insert groove is with respect to downward-sloping 35 ° of the horizontal plane of the long handle of L type machine swaging clamp body 7 part, and insert groove 6 matches with the quadrangle shape of blade 5.
Described chip breaking piece is a rectangle, and the pitch-row on its fixing hole and its four limit has nothing in common with each other.
The beneficial effect that the utility model reaches is can improve cutting speed 1-2 doubly through application in practice, reusable four times of a slice blade, improve cutter life 2-3 doubly, alleviated working strength of workers, improved production efficiency, installed the chip breaking piece additional and made smear metal, guaranteed processor's personal safety by the certain orientation chip removal, wide application, all applicable for vertical, horizontal big-and-middle-sized lathe.
Description of drawings
Fig. 1 is the powerful machine truck of a big cutting edge inclination cutter general structure schematic diagram;
Fig. 2 is powerful machine tool truck blade profile of big cutting edge inclination and a structural representation among Fig. 1;
Fig. 3 (a) and (b), (c), (d) are the amplification key diagram at each position among Fig. 2.
Embodiment
Figure 1 shows that the powerful machine truck of big cutting edge inclination cutter general structure schematic diagram.Leave the insert groove 6 that blade 5 is installed at the elbow of L type machine swaging clamp body 7 on partly, insert groove 6 matches with the quadrangle shape of blade 5, and by hex screw 2 with pad 3, reach chip breaking piece 4, blade 5 firmly is pressed in the solid insert groove 6 of machine swaging clamp body 7.This blade is a square, and there is fixing hole 8 at its center, and this blade has four identical main cutting edge and four angles of cutting-tool angle and requires the same point of a knife shape.The tool cutting edge angle of its main cutting edge is that 45 °, auxiliary angle are that 15 °, primary clearance are 6 °, the main cutting edge cutting edge inclination is 35 °, point of a knife is 120 °, the negative chamfered edge processing about-10 ° * 0.3mm is carried out at main cutting edge and point of a knife position, the anterior angle at main cutting edge position is-3 °～-5 °, the fineness of the sword of the anterior angle of machine swaging clamp sheet, relief angle point of a knife position and negative chamfered edge is not less than 0.8, and the cutting edge inclination at point of a knife position, anterior angle are 0 °.And to carry out the chamfered (shown in Fig. 2, Fig. 3 (a) and (b), (c), (d)) of circular arc to the point of a knife position of main cutting edge.35 ° of big cutting edge inclinations of its blade 5 are to realize for downward-sloping 35 ° with respect to the horizontal plane of machine swaging clamp body 7 by the last plane of insert groove 6.Set chip breaking piece 4 is a rectangle, its fixing hole is not or not the center, have nothing in common with each other with the pitch-row on its four limit, to adjust the width of chip breaker, so that control iron filings flow direction, be unlikely the injury operator, between the long handle of the last plane of insert groove 6 and L type machine swaging clamp body 7 horizontal plane partly downward-sloping 35 °.The powerful machine truck of the big cutting edge inclination of the utility model cutter reality is divided into the powerful machine truck of right big cutting edge inclination of being called of processing excircles special use cutter by the position difference of turning processing work; Process the powerful machine truck of left big cutting edge inclination of being called of end face special use cutter.
