Problems solved by technology

Since most of the cutting blades are made of alloys such as 65Cr4W3Mo2VNb, the price is relatively expensive.
Therefore, in the process of use, once the shearing edge groove wears out and cannot meet the cutting requirements, the entire shearing edge groove is discarded, which is easy to cause waste

Embodiment Construction

[0008] see figure 2 and image 3 , the present invention is provided with cutting edge grooves 2 on both sides of its blade body 1 . In order to cut multiple round bars at one time, the cross-section of the shearing edge grooves 2 on both sides of the blade body 1 is arc-shaped, and there are more than one, which are evenly distributed on both sides of the blade body. Of course, the cross-sectional shape of the shearing edge grooves can also be For other shapes, in order to cut profiles of different cross-sectional shapes.

[0009] In order to fix the blade body 1 on the shearing machine, at least one fixing hole (four in this embodiment) is opened on the blade body 1 .

Abstract

The invention relates to a shear blade with grooves. Two sides of a blade body are provided with shear blade grooves. The two sides of the blade body with the grooves are provided with the shear blade grooves and the shear blade grooves on two sides can be alternatively used for cutting round steel, so under the condition of the same material, the service life of the shear blade with the grooves can be prolonged by one time compared with that of the conventional shear blade with the grooves.

Description

technical field [0001] The present invention relates to a grooved shearing edge. Background technique [0002] The general length of the existing round steel is 6-9 meters, and it should be cut to the required length when it is used. figure 1 shown). Since most of the cutting blades are made of alloys such as 65Cr4W3Mo2VNb, the price is relatively high. Therefore, in the process of use, once the shearing edge groove is worn and cannot meet the shearing requirements, the entire shearing edge groove is discarded, which is easy to cause waste. Therefore, there is an urgent need for a method that can extend the cutting edge. SUMMARY OF THE INVENTION [0003] The problem to be solved by the present invention is how to prolong the service life of the shearing blade. In order to solve the above-mentioned technical problems, the present invention adopts the following technical scheme: a cutting edge groove is provided on both sides of the blade body of the invention with a gro...
