Abstract
The utility model relates to a cutting knife for metal proximate matter, which belongs to the technical field of cutting knife tools. The utility model is composed of a blade, wherein the head of the blade is provided with a V-shaped edge; the thickness of the blade is 6 to 25MM. When the utility model is operated, the V-shaped edge is matched with a lower tyre of the metal proximate matter to cut off the machined piece. The edge is sharp, the incision is smooth and the speed of cutting is high. The whole blade has the advantages of low machining cost and obvious production efficiency.
Description
Technical field
The utility model relates to a kind of shearing tool, the shape shear knife that specifically a kind of cutting metal section bar is used.
Background technology
At present, generally with the cast-cutting saw cutting, the cutting speed of cast-cutting saw is fast for the cutting metal section bar, and efficient is low.Next is that the weak point of gas cutting is that kerf quality is poor with the gas cutting cutting.Also having a kind of cutting mode is to adopt the band saw cutting, and the defective of band saw is the cutting cost height, and cutting efficiency is low, and service life is short.
Summary of the invention
It is good that problem to be solved in the utility model provides a kind of kerf quality, production efficiency height, the shape shear knife that cutting speed is fast.
The technical scheme that addresses the above problem is: the utility model is made up of blade, and the head of blade is one " V " font cutting edge.
Owing to adopted said structure, during work, " V " font cutting edge cooperates with the following tire of shape, and work piece is cut off.Cutting edge is sharp, and otch is mellow and full smooth, and cutting speed is fast.The processing cost of whole blade is low, and production efficiency is remarkable, the long service life of blade.
Description of drawings
Below in conjunction with the drawings and the specific embodiments the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing 1, blade 1 thickness of the present utility model is 6～25mm, and cutter head is " V " font cutting edge 2.According to designing requirement, cutter inside can be provided with holes for clamping, is used for clamp-on tool.As accompanying drawing 1,, a roundlet angle α is set in the tip of " V " font cutting edge 2 in order to make cutting edge 2 sharper.
During work, shear-blade 1 is connected with hydraulic press, cooperates with tire under the corresponding section bar, drive shear-blade 1 work with the pressure of hydraulic press, the tip of cutting edge 2 at first contacts the section bar that is cut, V limit crush-cutting section bar then, and moment both can cut off section bar.Because its speed is fast, the otch of institute's cut type material is quite smooth.This cutting knife is better than any one cutting tool of background technology.
Claims (2)
1, a kind of shape shear knife is made up of blade, it is characterized in that, the head of blade is one " V " font cutting edge.
2, shape shear knife according to claim 1 is characterized in that, described blade thickness is 6～25mm.
