The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
Embodiment 1
The solid carbide drill the utility model proposes expands ream-extrude cutter, as shown in Figure 1, comprise the cutter head 1 of being made by carbide alloy, bar portion 2 and shank 3, described cutter head comprises the bit part 1-1 that is positioned at its end, described bit part 1-1 rear portion is provided with reaming knife edge part 1-2 successively, fraising knife edge part 1-3 and crowded hole knife edge part 1-4, described reaming knife edge part processing diameter is greater than bit part processing diameter, described fraising knife edge part processing diameter is greater than reaming knife edge part processing diameter, described crowded hole knife edge part processing diameter is greater than reaming knife edge part processing diameter and is less than fraising knife edge part processing diameter.
Bit part, as shown in Figure 2, adopts general carbide drill standard.Cutting angle is according to work material and the different 140-150 ° that make of effect, 118-120 °, 90-110 °.
Reaming part, as shown in Figure 3, in order to improve the time kept in reserve of cutter and the complexity of minimizing cutter structure, primary cutting angles is generally chosen 30-50 ° and is advisable.And in order to improve the durability of cutter, relief angle is generally chosen 6-12 ° and is advisable.
Ream part, as shown in Figure 4, middle cutter band has played the effect of main smear metal, because of the cutting edge without sharp, therefore land can not be too wide, consider the complexity of producing, be designed to <0.1mm, so the difference of the processing diameter that expands, cuts with scissors can not be too large, be generally 0.015-0.025mm, relief angle is 30 °, if too large, the intensity of cutter will variation, too little meeting increasing friction force, affects workpiece surface roughness.
Crimping section, as shown in Figure 5, the width of middle cutter band portion, except the size of the final work processing of impact diameter, also directly affects the surface roughness of workpiece.Through test of many times and groping, the height that land is designed to the roughness of 0.7-0.8. land has the most at last affected the service life of cutter greatly, must be through grinding step.
Certainly, the solid carbide drill the utility model proposes expands ream-extrude cutter, and appearance and size is formulated according to different processing objects.
The novel proposition of this use a kind of can bore, cut with scissors, squeeze and to obtain whole hard alloy high-speed cutter, employing hardness is high, the carbide alloy of good toughness substitutes common brazed shank tool, cutter durability significantly improves, be particularly suitable for the High-speed machining in hole, cutting rotational speeds is per minute reaches up to ten thousand turning, be the 3-6 of conventional tool cutting speed doubly.The structure of ream-extrude cutter is improved simultaneously, the step such as once complete brill, hinge, squeeze, the error that avoided changing cutter, again causes in clamping cutter process increases, and has improved the machining accuracy in working (machining) efficiency and hole.This kind of cutter is mainly used in for the processing of PRECISION HOLE and the power set of military equipment such as automobile engine porthole mouth, oil duct combustion chamber, tappet bore and connecting rod, pump valve, the Precision Machining of firearms assembly.Machining accuracy reaches H7, H8, circularity, tapering < 1um, and the Ra value of surface roughness reaches below 0.4um.According to the difference of machine spindle speed, power, the cutting rotational speeds of whole hard alloy high-speed cutter can reach 3000～30000r/min.Processing diameter error within 0.005mm, angular error ± 1 ' within.
Embodiment, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
