Description

Technical Field

[0001] The utility model belongs to the technical field of rolling shears and relates to a hydraulic rolling shear. Background Art

[0002] As a common industrial processing tool, hydraulic shears are used in conjunction with motor pumps or manual pumps to achieve rapid shearing functions. Because hydraulic shears use hydraulic devices as the driving method, hydraulic shears can shear large steel materials. When traditional hydraulic shears shear some heavy rigid materials, the hydraulic cylinder drives the shear blades to merge and shear the steel. In the shearing process, due to the uneven density inside the steel, the shearing forces on different parts of the steel may be different, resulting in the phenomenon of misalignment of the two shear blades of the hydraulic shears during shearing. When the shearing forces on the shearing parts of the steel are too large to varying degrees, the shear blades may bend from the fixed axis, making the shearing machine unable to be used normally. Application No. 202022005670.6 discloses a hydraulic The shear stabilization device of a hydraulic shear for pressing mainly relates to a shear stabilization device, including a hydraulic shear and a shear stabilization device; the shear stabilization device is arranged on the hydraulic shear; the hydraulic cylinder of the hydraulic shear can drive the hydraulic shear to open and close; the shear stabilization device includes a double-axis hydraulic cylinder; an L-shaped connecting rod is connected to the telescopic rods at both ends of the double-axis hydraulic cylinder; one end of the L-shaped connecting rod is connected to a roller; the roller is in contact with the shearing surface of the hydraulic shear, and each of the hydraulic shearing surfaces is provided with a shearing surface slide groove; the roller can roll in the shearing surface slide groove of the hydraulic shear. The beneficial effect of the utility model is that the two shearing blades of the hydraulic shear can be easily stabilized in the axial direction to ensure that the shearing blades will not deflect outward when the hydraulic shear is shearing materials, thereby ensuring the normal use of the hydraulic shear.

[0003] Although the above-mentioned hydraulic shear device can improve the stability of the shear blade, since the shear surface chute is set at a low position, impurities are easily introduced into the shear surface chute during shearing, thereby causing the roller to slide obstructed, and improvement is needed.
