Novel double-cylinder hydraulic shear arm structure

Technical Field

The utility model relates to a shear device equipment field especially relates to a novel double-cylinder hydraulic pressure is cut and is cut arm structure.

Background

As shown in fig. 1-2, in the conventional double-cylinder hydraulic shear, because a welding rib plate (hereinafter referred to as an "I-shaped rib plate") in the two shear arm structures is a narrow strip-shaped structure, the I-shaped rib plate can prevent the two shear arms from splitting when shearing old metal; however, due to the fact that the strength of the shearing arm is insufficient due to the fact that the structural strength of the shearing arm is insufficient, the shearing force of the whole double-cylinder hydraulic shear is finally affected to be insufficient, and only old metal within a certain thickness range and a certain hardness range can be sheared. The double-cylinder hydraulic arm has a small application range and is difficult to shear for old metal with large thickness and high hardness.

Meanwhile, a part of welding seams formed in the welding process of the structure of the I-shaped rib plate is overlapped with the stress concentration part of the shear arm, so that a certain damage is formed on the motherboard through a welding heat affected zone formed on the surface of the motherboard by the welding seams. And a part of welding seams formed in the welding process of the structure of the I-shaped rib plate are vertical to the direction of tensile stress borne by the shear arm. The position relation that the welding seam is perpendicular to the tensile stress is very dangerous for welding structural parts, and a welding crack is easily derived from the position relation, so that the welding defect at the position has a great influence on the service life of the double-cylinder hydraulic shear.
