Abstract
The invention discloses a poly ethylene (PE) pipe cutting blade which comprises a blade body. The blade body is a metal sheet in a polygonal geometric shape. The blade body comprises two parallel planes, two side faces, four auxiliary cutting edge arc surfaces and four main cutting edge arc surfaces. Transition arc surface connecting two adjacent surfaces connect the auxiliary cutting edge arc surfaces and the main cutting edge arc surfaces. The transition arc surfaces are connected with the auxiliary cutting edge arc surfaces and the main cutting edge arc surfaces. The transition arc surfaces connect the planes and the auxiliary cutting edge arc surfaces. The main cutting edge arc surfaces form blade cutting edge parts which have certain included angles. Blade cutting edges and the horizontal plane are not located on the same straight line, so that the contact areas of the blade cutting edges are reduced, friction force is reduced, and the service life of the blade is prolonged; cutting is easy and convenient, the cutting speed is increased, and production efficiency is improved.
Description
Technical field
The present invention relates to a kind of cutting blade technical field, specifically a kind of PE pipe cutting blade.
Background technology
At present PE pipe cutting process, the cutting modes such as general employing handsaw, angle grinding machine, abrasive machine or electric saw, because the construction space had is narrow and small, forbid noise, or inflammable and explosive place, these cutting modes all can not be implemented, the simultaneously more coarse and out-of-flatness of the otch of these cutting modes, and chip not easy-clear, to remain in pipeline not easy to clean.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, and a kind of long service life is provided, cut light, accelerate cutting speed, improve a kind of PE pipe cutting blade of production efficiency.
The present invention adopts following technical scheme to realize for achieving the above object:
A kind of PE pipe cutting blade, comprise blade body, it is characterized in that: the body of described blade is the sheet metal with polygonal geometry, it has two parallel planes, two sides, four auxiliary knife edge cambered surfaces, four major cutting edge cambered surfaces, connect the transition circle cambered surface of two adjacent surfaces, transition cambered surface connects auxiliary knife edge cambered surface and major cutting edge cambered surface, and transition circle cambered surface connects auxiliary knife edge cambered surface, and transition circle cambered surface connects major cutting edge cambered surface; Transition cambered surface connects plane and auxiliary knife edge cambered surface, and major cutting edge cambered surface forms blade cutting edge; The angle α that described auxiliary knife edge cambered surface (3,3a) and auxiliary knife edge cambered surface (5,5a) are formed; The angle β that described major cutting edge cambered surface (4,4a) and major cutting edge cambered surface (6,6a) are formed; The angle γ that described blade cutting edge (9,14) is formed; Described blade cutting edge is that major cutting edge cambered surface intersects formation.
Aforesaid a kind of PE pipe cutting blade, is characterized in that: described angle α is 5 ° ~ 10 °; Described main folder angle β is 10 ° ~ 15 °; Described angle γ is 170 ° ~ 175 °.
Aforesaid a kind of PE pipe cutting blade, is characterized in that: the Rockwell hardness of described blade cutting edge (9,14) is 58 ~ 60HRC.
Blade cutting edge shape of the present invention is at a certain angle, and knife-blade and level, not on same straight line, make knife-blade contact area reduce, and reduces frictional force; The angle that major cutting edge cambered surface and auxiliary knife edge cambered surface are formed can be convenient to cutting PE pipeline, and the Different Plane of formation can form gap, prevents adhesion; Participate in the blade cutting edge of cutting, major cutting edge cambered surface and auxiliary knife edge cambered surface and form space curve distribution, increase the contact area with pipeline, effectively reduce Unit cutting force, thus the service life of blade is extended, cut light, accelerate cutting speed, improve production efficiency.
