Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel rolling equipment, specifically to a hydraulic shear energy storage device for large bar wire. Background Technology
[0002] Large bar production lines are complete production lines in the steel industry specifically designed for producing large-diameter bars, and are an important type of hot-rolled long product production line. These production lines mainly produce round steel, square steel, and other bar products with large diameters, and are widely used in machinery manufacturing, automotive industry, petrochemical industry, and other fields. The hydraulic shears on large bar production lines are key equipment on bar production lines in the metallurgical industry, mainly used for cutting hot-rolled or cold-rolled metal bars to length. The hydraulic tank provides pressure to the hydraulic shears. On large bar production lines, the hydraulic shears need to operate intermittently, requiring the hydraulic tank to remain operational. The electric motors powering the hydraulic tanks need to be continuously operating, and to ensure pressure, the motors have high power consumption. Therefore, it is necessary to design an energy storage device for the large bar hydraulic shears to reduce the number of motors and replace them with smaller motors to achieve energy savings. Summary of the Invention
[0003] The purpose of this invention is to provide a hydraulic shear energy storage device for large bar wires, which reduces the number of motors and replaces them with smaller motors, thus having the advantage of energy saving.
[0004] The technical solution adopted is as follows:
[0005] A hydraulic shear energy storage device for large bar wire includes a hydraulic station unit, an energy storage tank unit, and a delivery pump unit. The hydraulic station unit includes a hydraulic oil tank. The delivery pump unit includes a working pump and a standby pump, both of which are connected to the hydraulic station unit. The energy storage tank unit includes three energy storage groups, each containing multiple energy storage tanks. The delivery pump unit is equipped with a delivery pipe, which has three output pressurization lines. Each output pressurization line corresponds to one energy storage group, and each output pressurization line has multiple branch pipes, each connected to a corresponding energy storage tank. Each energy storage group is equipped with a pressure output pipe.
[0006] Preferably, there are two working pumps and one standby pump, and both the working pump and the standby pump have a power of 55KW.
[0007] Preferably, all of the energy storage tanks are equipped with pressure gauges.
[0008] Preferably, each of the output pressurization pipelines is equipped with an electrically controlled valve.
[0009] Compared to existing technologies, the advantages are:
[0010] This invention utilizes a delivery pump unit and a hydraulic station unit to pressurize an energy storage tank unit, which in turn provides pressure to the hydraulic shears of the large bar line, controlling the intermittent operation of the hydraulic shears. Compared to directly providing pressure to the hydraulic shears of the large bar line using a delivery pump unit and a hydraulic station unit, the use of a lower-power delivery pump unit achieves energy savings.

[0015] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 3 As shown:
[0016] Example 1: A hydraulic shear energy storage device for large bar wire includes a hydraulic station unit, an energy storage tank unit 4, and a delivery pump unit. The hydraulic station unit includes a hydraulic oil tank 1, which is existing technology and will not be described in detail here. The delivery pump unit includes a working pump 2 and a standby pump 3. Both the working pump 2 and the standby pump 3 are connected to the hydraulic station unit. The working pump 2 provides power to the hydraulic oil tank 1, and the standby pump 3 starts when the working pump 2 is in an abnormal state to ensure the power supply to the hydraulic oil tank 1.
[0017] The energy storage tank 4 unit includes three energy storage groups, and each energy storage group includes multiple energy storage tanks 4. The delivery pump unit is equipped with a delivery pipe, and the delivery pipe is equipped with three output pressurization pipes 5. Each output pressurization pipe 5 corresponds to one energy storage group. Each output pressurization pipe 5 is equipped with multiple branch pipes 6, and each branch pipe 6 is connected to a corresponding energy storage tank 4. Each energy storage group is equipped with a pressure output pipe, and the pressure output pipes are uniformly connected to the hydraulic shear line.
[0018] By using a delivery pump unit and a hydraulic station unit to pressurize the energy storage tank 4 unit, and then using the energy storage tank 4 unit to provide pressure to the hydraulic shears of the large bar line, the intermittent operation of the hydraulic shears of the large bar line is controlled. Compared with using a delivery pump unit and a hydraulic station unit to directly provide pressure to the hydraulic shears of the large bar line, a delivery pump unit with lower power can be selected, thus saving energy.
[0019] Example 2: A hydraulic shear energy storage device for large bar wire includes a hydraulic station unit, an energy storage tank unit 4, and a delivery pump unit. The hydraulic station unit includes a hydraulic oil tank 1, which is existing technology and will not be described in detail here. The delivery pump unit includes a working pump 2 and a standby pump 3. There are two working pumps 2 and one standby pump 3. The power of both the working pump 2 and the standby pump 3 is 55KW. Both the working pump 2 and the standby pump 3 are connected to the hydraulic station unit. The working pump 2 provides power to the hydraulic oil tank 1. The standby pump 3 starts when the working pump 2 is in an abnormal state to ensure the power supply to the hydraulic oil tank 1.
[0020] The energy storage tank unit 4 includes three energy storage groups, each of which includes multiple energy storage tanks 4. Each energy storage tank 4 is equipped with a pressure gauge. The delivery pump unit is equipped with a delivery pipe, which has three output pressurization lines 5. Each output pressurization line 5 corresponds to one of the energy storage groups. Each output pressurization line 5 has multiple branch pipes 6, which are connected to their respective energy storage tanks 4. Each energy storage group is equipped with a pressure output pipe, and each output pressurization line 5 is equipped with an electrically controlled valve. The pressure output pipes are uniformly connected to the hydraulic shear line.
[0021] The working principle is as follows:
[0022] The hydraulic oil in the hydraulic station unit is delivered to the accumulator tank 4 unit for pressurization using the delivery pump unit. The accumulator tank 4 unit then provides pressure to the hydraulic shears of the large bar line, controlling the intermittent operation of the hydraulic shears. When the working pump 2 malfunctions, the standby pump 3 is activated. Compared to directly providing pressure to the hydraulic shears of the large bar line using the delivery pump unit and the hydraulic station unit, a lower-power delivery pump unit can be selected, saving energy.
