Technical Field

The utility model belongs to the technical field of milling cutter, concretely relates to novel four sword alloy milling cutters.

Background

Since the end edge of the conventional four-edge milling cutter is generally flat and is generally flat on the machined surface of the workpiece, the cutting amount and the cutting speed of the cutter are relatively slow and the abrasion degree is high during the metal cutting process, so that the service life and the machining efficiency of the cutter are influenced. We have therefore proposed a new four-edged alloy milling cutter to solve the above problems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel four sword alloy milling cutter to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel four sword alloy milling cutter, includes the milling cutter body, the milling cutter body is hard alloy material structure, and the milling cutter body includes handle of a knife, cutter arbor and tool bit, the handle of a knife is located the back tip of milling cutter body, and the fixed cutter arbor that sets up rather than the integral type structure of the other end of handle of a knife, handle of a knife and cutter arbor are cylindrical structure, the cutter arbor is located and sets up on the preceding tip of milling cutter body and the cutter arbor and has revolved the sword tooth, the fixed tool bit that is provided with in top of cutter arbor, be equipped with four on the tool bit and be spiral helic.

Preferably, the bottom end of the milling cutter body is fixedly provided with a cutter holder, the cutter holder is a hard plastic socket, and a clamping hole matched with the rear end of the milling cutter body is formed in the cutter holder.

The cutter holder is arranged, so that the milling cutter can be placed.

Preferably, the relief angle of each side cutting edge is a circular arc relief angle, and an included angle between a tangential direction of the circular arc relief angle and a horizontal direction is degree.

The included angle between the tangential direction of the arc-shaped back angle and the horizontal direction is 13 degrees, so that the cutting amount and the cutting speed of the cutter can be greatly improved in the metal cutting process.

Preferably, the rotary cutter teeth are right-cutting type spiral rotary cutter teeth.

The right-cutting spiral rotary cutter teeth are arranged, so that the milling cutter can work stably, and the machining efficiency is high.

The utility model discloses a technological effect and advantage: this novel four-blade alloy milling cutter adopts right-hand cutting formula spiral rotary cutter tooth with rotary cutter tooth, can make milling cutter work steady, machining efficiency is higher, be four spiral helicine side cutting edges through being equipped with on the tool bit, establish the relief angle of end sword into convex relief angle, and the tangential direction of convex relief angle is 13 degrees with the contained angle of horizontal direction, the intensity increase of end sword like this, in metal cutting process, can improve the cut volume and the cut speed of cutter greatly, effectively improve production efficiency, and easy operation.
