Abstract
The invention relates to an end face cutter for a high-pressure rubber piston. The end face cutter comprises a cutter bar, a cutter bit is arranged at the front end of the cutter bar, a main blade adjacent to an auxiliary blade through a cutting blade is arranged on the cutter bit, the cutting blade is arranged in the middle of the cutter bit, and the cutting blade is an arc transition blade. A first auxiliary cutting face and a second auxiliary cutting face are arranged on two sides of the cutter bar respectively, an arc face with the middle protruded is arranged at the front end of the cutter bit, an include angle gamma is formed between the arc face and the first auxiliary cutting face, and the back end of the arc face is in arc transition connection with the second auxiliary cutting face. According to the end face cutter for the high-pressure rubber piston, a cutter tip is arranged in the middle of the cutter bit, both the horizontal face and the vertical face of the cutter bit are in a shape of arc, end face lips of the high-pressure rubber piston can be machined easily through the cutter, the size is stable, and demands of products are met.
Description
Technical field:
The present invention relates to a kind of tool for cutting machining, particularly relate to a kind of end face cutter for high-pressure rubber piston.
Background technology:
Existing high pressure rubber piston, because size is comparatively large, adopt compression-molded structures design to make, but this production method easily produces lip sharply, has the defect such as overlap, band fillet.And make high pressure rubber piston not reach instructions for use.
Summary of the invention:
The object of the invention is the above-mentioned deficiency in order to overcome prior art, there is provided a kind of structure simple, the special front tool of machinable high pressure rubber piston, solve existing high pressure rubber piston because of lip after compression molding not sharp-pointed, there is the situation such as overlap, band fillet, make product reach work instructions for use.
For solving the problems of the technologies described above, the present invention adopts following technical scheme to be:
End face cutter for high-pressure rubber piston, comprise knife bar (1), cutter head (2) is provided with in the front end of knife bar (1), cutter head (2) is provided with a major cutting edge (5) adjoined with auxiliary-blade (4) by cutting edge (3), the angle β formed between major cutting edge (5) and horizontal line is 3-4 °, the angle α formed between auxiliary-blade (4) and horizontal line is 45-50 °, and cutting edge (3) is arranged on the middle part of cutter head (2), and cutting edge (3) is arc transition sword; The first secondary cutting face (11) and the second secondary cutting face (12) is respectively equipped with in the both sides of knife bar (1), the front end of cutter head (2) is provided with the protruding arc surface (21) in middle part, between arc surface (21) and the first secondary cutting face (11), shape forms an angle γ, angle γ is 2-3 °, and the rear end of arc surface (21) is connected with the second secondary cutting face (12) arc transition.
Further, the angle β formed between described major cutting edge (5) and horizontal line is 3 °.
Further, the angle α formed between described auxiliary-blade (4) and horizontal line is 48 °.
Further, the radius of described cutting edge (3) is 1mm.
Further, the angle γ formed between described arc surface (21) and the first secondary cutting face (11) is 2.5 °.
Beneficial effect of the present invention is: the present invention is by studying machine cut high pressure rubber piston, test, manufacture and design end face cutter for high-pressure rubber piston, this cutting knife is by the medium position of point of a knife design at cutter head, level, the vertical plane of cutter head are circular shape, this cutting knife is used to process the end face lip of high pressure rubber piston relatively easily, and dimensionally stable, meet the requirement of product.
Accompanying drawing illustrates:
