The steel bar shearing machine in the steel bar shearing production line needs to be equipped with an upper shearing blade and a lower shearing blade when shearing steel bars. The prior art steel bar shearing machine has a very small inclined cutting angle of about 2°. That is, the structure of the shearing knife with an inclined cutting angle is that the upper blade installed on the upper knife seat has a very small tilt angle relative to the lower blade. Small. The shearing blade of the above-mentioned prior art steel bar shearing machine has the following shortcomings when cutting steel bars: 1. When starting to cut the steel bars, the blade comes into contact with multiple steel bars, and cutting the steel bars requires a large shearing force; 2. Shearing the steel bars When used, the blade is prone to slippage and has a short service life.
Content of the invention The purpose of this utility model is to overcome the shortcomings of the above-mentioned technology and provide an experimentally verified structure in which the upper blade mounted on the upper blade holder is tilted at a larger angle relative to the lower blade, which can Achieve high-quality cuts while increasing blade life. The technical solution to solve the above technical problems is an inclined shearing knife of a steel bar shearing machine. Its structure includes a shearing machine body; the following components are respectively fixed on the shearing machine body: a lower knife seat equipped with a lower blade; The upper knife seat of the inclined upper blade is also fixed with a driving device on the shearing machine body. The inclination angle between the inclined upper blade and the lower blade installed on the upper knife seat is = 4-15°. The beneficial effect of the utility model is to eliminate the phenomenon of the blade contacting multiple steel bars when starting to shear the steel bars, improve the performance of the whole machine, reduce the shearing force, reduce the damage of the shearing blade, and significantly improve the blade's durability. service life. It has the advantages of simple structure, reliable operation and high shearing efficiency.

Detailed Embodiments
The embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings. Figure 1 is a front view of the utility model; Figure 2 is an enlarged view of part A in Figure 1. As shown in Figures 1 and 2, the utility model provides an inclined shearing knife of a steel bar shearing machine. Its structure includes a shearing machine body 1; the following components are respectively fixed on the shearing machine body 1 and equipped with a lower blade. The lower knife seat 5 of 4; the upper knife seat 2 equipped with an inclined
3-type upper blade 3, and a driving device 7 is also fixed on the shearing machine body 1. The inclination angle between the inclined upper blade 3 and the lower blade 4 installed on the upper blade holder 2 is 0 =415°. The inclination angle is 3=8°. The working process of the present utility model will be described below. When it is necessary to cut the steel bar 6, the driving device 7 pushes the upper knife seat 2 and the inclined upper blade 3 to move downward to cut the steel bar 6. After completing the above action, the driving device 7 drives the upper knife seat 2 and the inclined upper blade 3 to return to the original position, thus completing a shearing cycle. Since the inclination angle between the inclined upper blade 3 and the lower blade 4 of the present invention is larger than that of the prior art, the blade is not easy to jump during the shearing process of steel bars, and the blade has a long service life.
Claims an inclined shearing knife of a steel bar shearing machine, the structure of which includes a shearing machine body (1); the following components are respectively fixed on the shearing machine body (1) and equipped with a lower blade The lower knife holder (5) of (4); the upper knife holder (2) equipped with an inclined upper blade (3), and a driving device (7) fixed on the shearing machine body (1), which is characterized by: The inclination angle β between the inclined upper blade (3) and the lower blade (4) installed on the upper blade holder (2) is 4 to 15°.
2. The inclined shearing knife of the steel bar shearing machine according to claim 1, characterized in that the inclination angle 3=8°.
Patent summary The utility model discloses an inclined shearing blade of a steel bar shearing machine. Its structure includes a shearing machine body; the following components are respectively fixed on the shearing machine body: a lower blade equipped with a lower blade; Knife holder; the upper knife holder is equipped with an inclined upper blade, and a driving device is fixed on the shearing machine body.
