Abstract

The utility model relates to a cutter with a toothlike main cutting edge. The cutter comprises a handle, one end of the handle is connected to a cutterhead, and ten sawteeth are uniformly distributed on the outer peripheral surface of the cutterhead, wherein every five sawteeth form a sawtooth group. The sawtooth group comprises a first sawtooth, a second sawtooth, a third sawtooth, a fourth sawtooth, and a fifth sawtooth, the upper surface of each sawtooth is provided with a boss, and the bosses on the five sawteeth in the sawtooth group are mutually staggered. The utility model has the advantages of reduced wear, high production efficiency, and good stability.

Description

A kind of main cutting edge is the cutter of profile of tooth

Technical field

The utility model relates to the cutter that a kind of main cutting edge is profile of tooth.

Background technology

At present, when pack alloy SGE cylinder head cover sidewall channels, the T-shaped cutter that generally adopts high-speed steel and hard to close material carrys out milling, can adopt helical teeth, side set design to guarantee machining accuracy on cutterhead, but working (machining) efficiency is slow, and cutter is easy to wear easily broken.

Summary of the invention

The purpose of this utility model is in order to overcome above deficiency, provides a kind of and reduces wearing and tearing, production efficiency a kind of main cutting edge high, good stability is the cutter of profile of tooth.

The purpose of this utility model is achieved through the following technical solutions: a kind of main cutting edge is the cutter of profile of tooth, comprise handle of a knife, one end of handle of a knife is connected with cutterhead, be evenly distributed with ten sawtooth on the outer peripheral face of cutterhead, wherein every five sawtooth are one group of sawtooth group, the sawtooth group comprises the first sawtooth, the second sawtooth, the 3rd sawtooth, the 4th sawtooth, the 5th sawtooth, is equipped with boss on the upper surface of each sawtooth, the setting of staggering mutually of the boss on five sawtooth in the sawtooth group.

Further improvement of the utility model is: the angle of inclination of the tangent plane of each sawtooth is 5 °.

Further improvement of the utility model is: the angle between the adjacent inclined-plane in the tangent plane of each sawtooth and left side is 70 °.

Further improvement of the utility model is: the upper surface of the first sawtooth, the 3rd sawtooth and the 5th sawtooth is provided with three boss, and the upper surface of the second sawtooth and the 4th sawtooth is provided with two boss.

The utility model compared with prior art has the following advantages:

The utility model reduces cutter generation vibration when cutting by the mode that increases the number of teeth and by straight-tooth, changed into according to tooth, thereby reduces cutting force, improves cutter life.The utility model reduces the wearing and tearing and cutting breaking of producing cutter by improved tool, enhance productivity, guarantee the stability of board, product quality after processing is stable before with the size ratio, technique is more stable, the number of times of changing and adjust cutter because of the cutter factor has reduced, and production efficiency has improved, cost.

The specific embodiment:

In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the utility model, does not form the restriction to the utility model protection domain.

show as Fig. 1 to Fig. 7 a kind of embodiment that a kind of main cutting edge of the utility model is the cutter of profile of tooth, comprise handle of a knife 1, one end of handle of a knife 1 is connected with cutterhead 2, be evenly distributed with ten sawtooth on the outer peripheral face of cutterhead 2, reduce cutter generation vibration when cutting by the mode that increases the number of teeth and by straight-tooth, changed into according to tooth, thereby reduce cutting force, improve cutter life, wherein every five described sawtooth are one group of sawtooth group, as Fig. 3 extremely as shown in Figure 7, the sawtooth group comprises the first sawtooth 3, the second sawtooth 4, the 3rd sawtooth 5, the 4th sawtooth 6, the 5th sawtooth 7, be equipped with boss 8 on the upper surface of each sawtooth, the setting of staggering mutually of boss 8 on five sawtooth in the sawtooth group, the first sawtooth 3, the upper surface of the 3rd sawtooth 5 and the 5th sawtooth 7 is provided with three boss 8, the upper surface of the second sawtooth 4 and the 4th sawtooth 6 is provided with two boss 8.The tilt angle alpha of the tangent plane of each sawtooth 3 is 5 °, and the angle β between the adjacent inclined-plane in the tangent plane of each sawtooth 3 and left side is 70 °.

The utility model reduces the wearing and tearing and cutting breaking of producing cutter by improved tool, enhance productivity, guarantee the stability of board, product quality after processing is with size than stable before, and technique is more stable, and the number of times of changing and adjust cutter because of the cutter factor has reduced, production efficiency has improved, bring up to 15 products of processing in 1 hour by 4 products of processing in former 1 hour, reduce cutter consumption, cost.
