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 pipes cutting blade.
Background technology
In present PE pipe cutting process, typically using cutting modes such as handsaw, angle grinder, abrasive machine or electric saws, due to
Some construction spaces are narrow and small, forbid noise, or inflammable and explosive place, these cutting modes to be unable to implement, while this
The otch of a little cutting modes is relatively rough and out-of-flatness, and chip not easy-clear, remains in pipeline and is not easily cleaned.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, and a kind of long service life is provided, cut light, quickening
Cutting speed, improves a kind of PE pipes cutting blade of production efficiency.
The present invention adopts the following technical scheme that realization for achieving the above object：
A kind of PE pipes cutting blade, including blade body, it is characterised in that：The body of described blade is with polygon
Geometry sheet metal, which has parallel two plane, two sides, four auxiliary knife edge cambered surfaces, four major cutting edge arcs
Face, connects the transition circle cambered surface of two adjacent surfaces, transition cambered surface connection auxiliary knife edge cambered surface and major cutting edge cambered surface, transition circle cambered surface
Connection auxiliary knife edge cambered surface, transition circle cambered surface connection major cutting edge cambered surface；Transition cambered surface connects plane and auxiliary knife edge cambered surface, operator
Sword cambered surface forms blade cutting edge；The auxiliary knife edge cambered surface（3、3a）With auxiliary knife edge cambered surface（5、5a）The angle α of formation；It is described
Major cutting edge cambered surface（4、4a）With major cutting edge cambered surface（6、6a）The angle β of formation；Described blade cutting edge（9、14）The angle of formation
γ；Described blade cutting edge is that major cutting edge cambered surface is crossed to form.
A kind of aforesaid PE pipes cutting blade, it is characterised in that：The angle α is 5 °～10 °；The main folder angle beta is 10 °
～15 °；The angle γ is 170 °～175 °.
A kind of aforesaid PE pipes cutting blade, it is characterised in that：The blade cutting edge（9、14）Rockwell hardness be 58～
60HRC。
The blade cutting edge shape of the present invention is at a certain angle, and knife-blade is not arranged on the same straight line with level, makes blade
Blade contact area is reduced, and reduces frictional force；The angle that major cutting edge cambered surface and auxiliary knife edge cambered surface are formed can be easy to cut PE
Pipeline, the Different Plane of formation can form gap, prevent adhesion；Participate in blade cutting edge, major cutting edge cambered surface and the auxiliary of cutting
Blade cambered surface forms space curve distribution, increases the contact area with pipeline, effectively reduces Unit cutting force, thus extends
The service life of blade, cuts light, accelerates cutting speed, improves production efficiency.
