Problems solved by technology

[0003] For the existing hydraulic shearing circuit, if it is necessary to ensure rapid shearing while ensuring no-load fast forwarding, it is necessary to select a large-capacity accumulator, which increases the cost and volume of the equipment. The present invention provides a A kind of hydraulic transmission circuit of oblique blade shearing machine. When the circuit is empty, the rapid advance of the shearing cylinder is realized through the hydraulic differential circuit without the need for the accumulator to be put into work; When working, the accumulator is put into work, the rodless side of the shearing cylinder enters the high-pressure oil, and the rod side receives the oil, so as to realize the high force output of the shearing cylinder and ensure the high shearing speed

Description

Technical field: [0001] The invention belongs to the technical field of iron and steel plate processing, and in particular relates to a hydraulic transmission circuit of an oblique blade shearing machine, which is suitable for the hydraulic transmission of a rolling production line or an experimental line shearing machine. Background technique: [0002] In the strip steel production line or the strip steel test line, the shearing machine is one of the most widely used single equipment, mainly used for flattening, trimming or shearing the strip steel. The most widely used cutting machines are figure 1 In the crank slider structure shown, when the shearing cylinder is pushed out, the push rod moves forward under the drive of the shearing cylinder and drives the upper connecting rod and the lower connecting rod to move forward. At this time, the frame where the lower shearing edge is located moves upwards under the constraints of the guide rail. When the strip to be cut is pre...
