The invention discloses a high-speed shearing device which comprises an oil tank, a steel plate shearer hydraulic cylinder, an energy accumulator and a material pressing cylinder. Oil pipes are led out from the oil tank and divided into three branches after being connected with an oil pump. The first branch is connected with a pressure reducing valve and a magnetic exchange valve YV4 in sequence, then is connected to the energy accumulator on the one hand, and connected to the steel plate shearer hydraulic cylinder on the other hand after being connected with a one-way valve. The second branch is connected with a one-way sequence valve, then is connected to the steel plate shearer hydraulic cylinder on the one hand, and returns to the oil tank on the other hand after being connected with an electromagnetic relief valve YV3. The third branch is connected to the material pressing cylinder on the one hand after being connected to a magnetic exchange valve YV2, and returns to the oil tank on the other hand after being connected with an electromagnetic relief valve YV1. The first branch, the second branch and the third branch are connected with a pressure relay in a shared mode. The pressure relay is electrically connected with the electromagnetic relief valve YV1, the electromagnetic relief valve YV3, the magnetic exchange valve YV2 and the magnetic exchange valve YV4 respectively through an electrical control system. According to the high-speed shearing device, only a motor low in energy consumption is selected to drive the oil pump to work, so that work efficiency is greatly improved, and noise, cost, electricity consumption, the oil temperature and the occurrence rate of errors are reduced.
Description
technical field [0001] The invention relates to the field of shearing machines, in particular to a high-speed shearing device. Background technique [0002] Shearing machine is an important basic processing equipment in sheet metal manufacturing industry. The traditional shearing machine generally adopts hydraulic transmission, the oil pump supplies oil, and the shearing speed is determined according to the displacement of the oil pump and the bore size of the oil cylinder. Often, due to the increase of the oil pump row, the oil pump motor is relatively increased, and at the same time, the noise, cost, and Power consumption, oil temperature, faults, etc. increase. Contents of the invention [0003] The purpose of the present invention is to provide a high-speed shearing device, which only needs to use a motor with low energy consumption to drive the oil pump to work, so as to improve work efficiency and reduce noise, cost, power consumption, oil temperature and failur...
