Abstract
The utility model relates to a mechanically fixed intermittent-cutting indexable turning tool, which can be mounted in various common vertical and horizontal lathes and numerically controlled lathe tool rests, and is used for large-allowance cutting for various irregular ductile and brittle materials. The mechanically fixed intermittent-cutting indexable turning tool comprises a toolbar cutting portion with a 75-degree tool cutting edge angle, a 20-degree tool cutting edge inclination and a 6-degree main relief angle. Both the upper surface and the lower surface are provided with a hard alloy indexable blade with a 30-degree front angle, the hard alloy indexable blades are tightly pressed on a shim of a toolbar tool containing groove by an eccentric shaft, the eccentric shaft is fixed by M5mm set screws with dog points, and the mechanically fixed intermittent-cutting indexable turning tool is simple and convenient in assembly and disassembly and high in processing efficiency.
Description
Technical field
The utility model relates to a kind of mechanical clamping type and is interrupted the cutting indexable turning tool, be particularly related to a kind of can being installed in all kinds of common vertical and horizontal lathes and the numerically controlled lathe knife rest, a kind of mechanical clamping type of some irregular all kinds of ductility and fragile material is interrupted the cutting indexable turning tool.
Background technology
When all kinds of common vertical and horizontal lathes and lathe in machining irregular part external diameter, as adopt conventional high-speed steel or hard alloy rotatable billmpse tool to cut, because workpiece is bigger to the shock loading of cutter, blade can burst apart very soon and scrap, thereby working (machining) efficiency is extremely low and the cutter wastage is big.
Summary of the invention
The purpose of this utility model will overcome above-mentioned drawback exactly, provides tool clamping type a kind of simple in structure, easy to make and with low cost to be interrupted the cutting indexable turning tool.
The technical solution of the utility model is as follows: a kind of mechanical clamping type is interrupted the cutting indexable turning tool, can be installed in all kinds of common vertical and horizontal lathes and the numerically controlled lathe knife rest and use, it makes into 75 ° of tool cutting edge angles with knife bar cutting knife holder slot partly, 6 ° of 20 ° of cutting edge inclinations and primary clearances, the cemented carbide indexable insert upper and lower surface all is made as 30 ° of anterior angles, adopt 1 eccentric shaft that it is pressed on the edge bearing of knife bar knife holder slot, the cylinder end clamping fixed screw fixed eccentric shaft, in making the machining of big surplus, the firm non-loosening of blade.
The utility model is because with the effect of upper knife edge geometric angle, and when all kinds of ductility and fragile material were interrupted cutting, cutting data was: u=40～60m/min, f=0.20～0.35mm/r, α
p=8～12mm, tool life is done the blade transposition after can using 3～5h continuously, load and unload easy, the working (machining) efficiency height.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described.
Fig. 1 is the cutaway view of the utility model Fig. 3 structure;
Fig. 2 is the left view of the utility model Fig. 3;
Fig. 3 is a front view of the present utility model.
Wherein: in the cutaway view of Fig. 3 structure, 1, cemented carbide indexable insert, 2, cylinder end clamping fixed screw, 3, eccentric shaft, 5, sunk screw, 6, edge bearing.
Specific embodiments
For technological means of the present utility model, creation characteristic are further understood, set forth below in conjunction with concrete diagram.
As shown in Figure 1, upper and lower surface all is made as the carbide chip 1 of 30 ° of anterior angles, blade is after Passivation Treatment, be loaded on the edge bearing that is provided with 30 ° of inclined-planes 6 of knife bar 4, insert eccentric shaft 3, the eccentric shaft that has eccentric throw 0.5～0.8mm is entered in 1 the hole, turn clockwise and 3 be pressed on 6 the inclined-plane 1, screw M5mm cylinder end clamping fixed screw 2, be pressed in 3 the groove and do not move it and rotate, when blade needs transposition, unclamp 2, be rotated counterclockwise 3 holes of also extracting out to the right, can carry out the blade transposition away from 1.
As shown in Figures 2 and 3,6 ° of 25 ° of the cutting edge inclinations of cutter, 75 ° of tool cutting edge angles and primary clearances are all finished in making the knife bar process in succession.
Because the processing parts material is different, blade material can be homemade YT14, YG8, YW1-3, now adopt the waste and old blade of 41910v-w model to be cut into 30 ° of anterior angle utilizations at wire cutting machine tool, the later trend big according to the cutter consumption, to make powder compaction device, this carbide chip of small lot batch manufacture.
Claims (2)
1. a mechanical clamping type is interrupted the cutting indexable turning tool, can be installed in all kinds of common vertical and horizontal lathe and the interior uses of numerically controlled lathe knife rest, it is characterized in that partly being 75 ° of tool cutting edge angles in the knife bar cutting, 6 ° of 20 ° of cutting edge inclinations and primary clearances, the cemented carbide indexable insert upper and lower surface is 30 ° of anterior angles, 1 eccentric shaft is pressed on it on edge bearing of knife bar knife holder slot, the cylinder end clamping fixed screw fixed eccentric shaft.
2. mechanical clamping type according to claim 1 is interrupted the cutting indexable turning tool, and the eccentric throw that it is characterized in that described 1 eccentric shaft is 0.5～0.8mm.
