Shear blade structure of bar cold shear

The utility model relates to the field of steel production, in particular to a bar cold shear blade structure which comprises an upper shear blade and a lower shear blade. A plurality of shearing grooves B are formed in the shearing side of the lower shearing blade in the length direction; the shearing grooves A and the shearing grooves B are the same in number and matched in position. Wherein the shearing side of the upper shearing blade comprises a first shearing surface and a second shearing surface, and the first shearing surface is higher than the second shearing surface. The utility model mainly aims to provide the shear blade structure of the bar cold shear, the shear force borne by the shear blade at the same time is reduced in a mode of cutting the bar in sections, and the safety pin is prevented from being broken. 本实用新型涉及钢材生产领域，具体涉及一种棒材冷剪剪刃结构，包括，上剪刃，所述上剪刃的剪切侧沿长度方向设置有多个剪切槽A；下剪刃，所述下剪刃的剪切侧沿长度方向设置有多个剪切槽B；所述剪切槽A、剪切槽B数量相同，位置相匹配；其中，所述上剪刃的剪切侧包括第一剪切面、第二剪切面，所述第一剪切面高出于所述第二剪切面设置。本实用新型的主要目的在于提供一种棒材冷剪剪刃结构，通过将棒材进行
