Problems solved by technology

Due to the different specifications of the strip steel on the market, it is very inconvenient for the shearing of the strip steel, so a hydraulic shear that can continuously adjust the gap between the cutting blades to adapt to the thickness of the strip steel of different specifications is required.

Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings: a hydraulic inclined blade shear, including a frame, an upper beam, a frame center column, a shear cylinder, a side clearance adjustment device, an upper knife rest and a lower knife rest; The frame is connected by 4 large tie rods and 2 small tie rods to form a closed frame body; the upper beam is welded by multiple steel plates and fixed on the upper part of the frame. , so the requirements for its strength and rigidity are relatively high; the middle column of the frame is the intermediate support connecting the upper beam and the lower tool rest, and its force is relatively large, and it is distributed on both sides of the frame; the shearing cylinder is installed on the The bottom of the upper beam on the frame drives the upper knife rest to move downward, so that the upper shearing edge can complete the cutting work; the side clearance adjustment device is...

Abstract

The invention discloses hydraulic inclined blade shears which comprise a machine frame, an upper cross beam, machine frame middle columns, a shearing oil cylinder, a backlash adjusting device, an upper tool rest and a lower tool rest. According to the machine frame, four large pull rods and two small pull rods are connected into a closed frame body. The upper cross beam is formed by welding a plurality of steel plates and fixed to the upper portion of the machine frame. The machine frame middle columns are middle supports for connecting the upper cross beam with the lower tool rest and are distributed on the two sides of the machine frame. The shearing oil cylinder is installed at the bottom of the upper cross beam of the machine frame and drives the upper tool rest to move downwards, so that an upper shearing blade completes shearing operation. The backlash adjusting device is fixed to one side of the machine frame, and the minimum shearing blade gap position is controlled through a limiting switch. According to the hydraulic inclined blade shears, a prestress machine frame assembling structure is adopted, the weight is reduced by 70 t compared with the traditional design, and the equipment production cost is reduced. A series-connection oil cylinder synchronization mode is adopted by the shearing oil cylinder, the load-deflection resistance is high, operation is stable, and vibration is small. The backlash adjusting device is additionally arranged, and the shearing blade gap is kept unchanged.

Description

technical field [0001] The invention relates to the technical field of hydraulic shears, in particular to a hydraulic inclined blade shear. Background technique [0002] When processing steel parts, when encountering irregular strips or broken strips, it is necessary to use hydraulic shears to cut off the irregular strips. The hydraulic shear is composed of a fixed shear blade and a shear blade. When shearing, the shear blade is driven and tangent to the fixed blade to cut the strip steel. For strips of different thicknesses, the gaps between the required cutting edges are different. Because the specifications of the strips on the market are different, it is very inconvenient for the shearing of the strips. Therefore, a hydraulic shear that can continuously adjust the gap between the cutting blades to adapt to the thickness of the strips of different specifications is required. Contents of the invention [0003] The purpose of the present invention is to overcome the def...
