Abstract
The utility model relates to a welding cutter. The welding cutter is characterized in that one end of a cutter body is provided with a blade which is provided with a front angle of 5 to 40 degrees. During use, the welding cutter requires no grinding of the front angle of the blade, saves time and labor, guarantees stable parameters of the front angle, stable work and stable work quality, and realizes improvement of working efficiency and increase of the service lifetime. A chip breaker groove is formed naturally by an installing groove of the blade on the cutter body and the front portion of the blade and realizes smooth chip removal.
Description
Technical field
The utility model relates to the technical field of hardware & tools class, specifically a kind of positive rake angle brazed shank tool.
Background technology
At present; Known brazed shank tool anterior angle all is that (the anterior angle here is meant the rake face measured in the orthogonal plane and the angle between the basal plane to zero degree; Basal plane is: Chosen Point and height such as workpiece axis of rotation grade on the supposition cutting edge; The normal plane of the cutting speed direction of Chosen Point), operating efficiency is not high during use, and crudy is undesirable.Caloric value is big, and cutter life is short.
Because of existing brazed shank tool often also adopts zero degree hook, during work in order to obtain desirable crudy and operating efficiency, how with the anterior angle reconditioning to the 5-40 degree, cutter grinding is time-consuming takes a lot of work, grinding quality is unstable, work quality is unstable, cutter life is short.
Summary of the invention
The purpose of the utility model is to provide a kind of improved brazed shank tool, and it can overcome when cutter uses in the prior art needs the reconditioning anterior angle, and reconditioning is time-consuming takes a lot of work, and grinding quality is unstable, and work quality is unstable, the some shortcomings that cutter life is short.
To achieve these goals, the technical scheme of the utility model is: a kind of brazed shank tool, and it mainly comprises cutter hub, it is characterized in that: an end of cutter hub is provided with blade, and blade is provided with 5-40 degree anterior angle.
During use, the cutter of the utility model does not need the reconditioning anterior angle, time and labour saving, anterior angle parameter stability; Reliable operation, work quality is stable, and work efficiency improves; Cutter life improves, and the part of removing because of the manufacturing anterior angle on the blade forms chip-breaker, favourable chip removal naturally with the sunk part of cutter hub.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the A-A profile of Fig. 1.
Fig. 3 is the front view of blade.
Fig. 4 is the vertical view of blade.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe.
The utility model mainly comprises cutter hub 2, and its difference with the prior art is: an end of cutter hub 2 is provided with blade 1, and blade is provided with 5-40 degree anterior angle.
In force, on blade, anterior angle made the work angle of 5-40 degree, be welded to again on the cutter hub, become the positive rake angle cutter.The manufacture craft of cutter is constant basically, and the blade material is constant, and cost reduces; Do not need the reconditioning anterior angle during use, time and labour saving, anterior angle parameter stability; Reliable operation, work quality is stable, and work efficiency improves; Cutter life improves, and the part of removing because of the manufacturing anterior angle on the blade forms chip-breaker, favourable chip removal naturally with the sunk part of cutter hub.
