Abstract

The utility model relates to an indexable hard alloy end face blade which uses a corresponding equilateral and equiangular blade as a basic structure. The utility model is characterized in that a tapered and slim small shallow chip breaker 4 which uses a tip 2 as a starting point and is slightly inclined with the trend of a cutting edge 1 is arranged in the original big chip breaker 3. The utility model has favorable actions of rolling chips, guiding chips and breaking chips and solves the problems that the chips easily damage the surfaces of processed workpieces and endanger operators' safety and the blade is easy to break up when the original cutting tool cuts so as to prolong the service life of the cutting tool.

Description

Indexable carbide alloy end face blade

The utility model is a kind of machine clip variable-position carbide chip, the improvement of the corresponding type blade of equilateral isogonism that uses when particularly building up by welding is carried out in turner.

Existing equilateral isogonism carbide alloy shaping blades, as A type, H type etc., though on its front, be provided with along the chip-breaker of blade direction, its chip-breaker width is bigger, in turning end face process, can not handle smear metal well, promptly can not roll up bits, chip breaking effectively, smear metal is evenly in time discharged.

The purpose of this utility model is to provide a kind of existing equilateral corresponding type carbide chip of isogonism that waits can carry out the building up by welding blade that smear metal is handled better.

The technical solution of the utility model is: keep the existing corresponding type carbide chip of equilateral isogonism planform constant, on its original big chip-breaker surface, setting up one is starting point with the point of a knife position, slightly is inclination, the shallow little chip-breaker that taper is long and narrow with the blade trend.

The utility model blade has good volume bits, dust lead, chip breaking effect, can make chip curling, is spiral form and fracture discharge in time along conduit.Thereby following effect is arranged: when having solved original blade cut chip removal not smooth, smear metal easily is involved on the chuck or workpiece of rotation, the surface of the work that damage processes or cause injury to the operator; The original high hard smear metal pressing blade that can not in time discharge, the problem that blade is burst apart is solved, and has improved the working life of blade greatly.

Embodiment is described further below in conjunction with accompanying drawing.

The axonometric projection graph of Fig. 1 the utility model embodiment one, the front view of Fig. 2 example one, the local amplification view of Fig. 3 A-A, the axonometric projection graph of Fig. 4 embodiment two.1-blade among the figure, 2-point of a knife, 3-original big chip-breaker, 4-newly establish shallow little chip-breaker.

Fig. 1, embodiment illustrated in fig. 4ly on equilateral isogonism A type and H type carbide chip basis, do corresponding improvement respectively and design.This improvement design outside the equilateral isogonism A of deconditioning type, the H type blade, also is suitable for the carbide chip of multiple corresponding types such as J type, Y type.The long and narrow shallow little oblique chip-breaker of taper 4 is a starting point with the nose part, and the notch upper edge and the blade angle of cut are about 5～9.5 degree.Starting point place groove width is 0.9～1.5 millimeter, and whole groove width is controlled at 0.9～2.0 millimeter.About 0.2～0.5 millimeter of groove depth.
