Description

一种带锯床节能装置 Energy-saving device for band sawing machine

技术领域technical field

本实用新型涉及一种金属带锯床，特别是一种带锯床节能装置。The utility model relates to a metal band sawing machine, in particular to an energy-saving device for the band sawing machine.

背景技术Background technique

金属带锯床是工件断面锯切加工的重要设备，其工作时，工件通常由夹紧油缸驱动活动钳夹紧。当工件夹紧后，为了保证工件不发生松动，在整个锯切过程中，现有带锯床中的油泵始终在不停地工作，使夹紧油缸保持一定油压，以保证活动钳有足够的夹紧力。但由于工件夹紧后其油泵一直在工作，这样，不仅影响油泵及其它液压元件的实用寿命，而且需要耗费大量电能。The metal band sawing machine is an important equipment for sawing and processing the workpiece section. When it is working, the workpiece is usually clamped by the movable clamp driven by the clamping cylinder. After the workpiece is clamped, in order to ensure that the workpiece does not loosen, the oil pump in the existing band sawing machine is always working continuously during the entire sawing process, so that the clamping oil cylinder maintains a certain oil pressure, so as to ensure that the movable tongs have enough clamping force. But because its oil pump is always working after the workpiece is clamped, like this, not only affects the practical life of oil pump and other hydraulic components, and needs to consume a large amount of electric energy.

发明内容Contents of the invention

本实用新型提供一种带锯床节能装置，使夹紧油缸驱动活动钳夹紧工件后，油泵能够自动停机节能。为此，本实用新型采用以下技术方案：The utility model provides an energy-saving device for a band sawing machine, which enables an oil pump to automatically stop and save energy after a clamping oil cylinder drives movable pliers to clamp a workpiece. For this reason, the utility model adopts the following technical solutions:

一种带锯床节能装置，包括一夹紧液压回路中的油缸、油泵、油泵电机、过滤网、溢流阀、三位四通电磁阀和夹紧油缸，三位四通电磁阀与夹紧油缸之间的供油道中设有液控单向阀，其特征是：所述液控单向阀与夹紧油缸之间的供油道中设有压力继电器，压力继电器连接和控制油泵电机。An energy-saving device for a band sawing machine, comprising an oil cylinder in a clamping hydraulic circuit, an oil pump, an oil pump motor, a filter screen, an overflow valve, a three-position four-way solenoid valve and a clamping oil cylinder, and a three-position four-way solenoid valve and a clamping oil cylinder A hydraulically controlled one-way valve is provided in the oil supply passage between them, and the feature is that: a pressure relay is provided in the oil supply passage between the hydraulically controlled one-way valve and the clamping oil cylinder, and the pressure relay is connected to and controls the oil pump motor.

本实用新型的有益效果是：通过在夹紧液压回路中增设压力继电器和液控单向阀，在工件夹紧后，能使油泵自动停机节能。The beneficial effects of the utility model are: by adding a pressure relay and a hydraulic control check valve in the clamping hydraulic circuit, after the workpiece is clamped, the oil pump can be automatically stopped to save energy.

具体实施方式Detailed ways

附图标注说明：1-夹紧油缸、2-压力继电器、3-液控单向阀、4-三位四通电磁阀、5-溢流阀、6-过滤网、7-油泵、8-油泵电机、9-油缸。Notes on drawings: 1-clamping oil cylinder, 2-pressure relay, 3-hydraulic control check valve, 4-three-position four-way solenoid valve, 5-overflow valve, 6-filter, 7-oil pump, 8- Oil pump motor, 9-oil cylinder.

如图1所示，一种带锯床节能装置，包括一夹紧液压回路中的油缸9、油泵7、油泵电机8、过滤网6、溢流阀5、三位四通电磁阀4和夹紧油缸1，三位四通电磁阀4与夹紧油缸1之间的供油道中设有液控单向阀3，所述液控单向阀3与夹紧油缸1之间的供油道中设有压力继电器2，压力继电器2连接和控制油泵电机8。As shown in Figure 1, an energy-saving device for a band sawing machine includes an oil cylinder 9 in a clamping hydraulic circuit, an oil pump 7, an oil pump motor 8, a filter screen 6, an overflow valve 5, a three-position four-way solenoid valve 4 and a clamping Oil cylinder 1, a hydraulic control check valve 3 is provided in the oil supply passage between the three-position four-way solenoid valve 4 and the clamping cylinder 1, and a hydraulic control check valve 3 is provided in the oil supply passage between the hydraulic control check valve 3 and the clamping cylinder 1. There is a pressure relay 2, and the pressure relay 2 is connected to and controls the oil pump motor 8.

所述液控单向阀3可以为叠加式液控单向阀。The hydraulically controlled one-way valve 3 may be a superimposed hydraulically controlled one-way valve.

本实用新型工作时，当夹紧液压回路中的夹紧油缸1驱动带锯床上的活动钳夹紧工件后，通过压力继电器2作用，油泵电机8断电，油泵7停机。When the utility model works, after the clamping oil cylinder 1 in the clamping hydraulic circuit drives the movable pliers on the band sawing machine to clamp the workpiece, the oil pump motor 8 is powered off by the pressure relay 2, and the oil pump 7 stops.

油泵7停机后，其夹紧液压回路中的液控单向阀3立即关闭，使该夹紧液压回路中能够保持一定压力，从而保证工件的夹紧。本实用新型夹紧液压回路中的压力最长时间可达3小时。After the oil pump 7 stops, the hydraulic control check valve 3 in its clamping hydraulic circuit is closed immediately, so that a certain pressure can be maintained in the clamping hydraulic circuit, thereby ensuring the clamping of the workpiece. The maximum time for the pressure in the clamping hydraulic circuit of the utility model can reach 3 hours.

当上述夹紧液压回路中的压力减少到压力继电器2设定的最小值时，压力继电器2通过电路控制油泵重新开机工作，补偿液压回路中减少的压力。When the pressure in the above-mentioned clamping hydraulic circuit decreases to the minimum value set by the pressure switch 2, the pressure switch 2 controls the oil pump to restart to work through the circuit to compensate for the reduced pressure in the hydraulic circuit.

当液压回路中的压力达到需要的设定值后，压力继电器2又控制油泵电机8断电，油泵7停机。When the pressure in the hydraulic circuit reaches the required set value, the pressure relay 2 controls the oil pump motor 8 to cut off the power, and the oil pump 7 stops.

本实用新型与现有带锯床上的夹紧液压回路相比，只在液控单向阀3与夹紧油缸1之间的供油道中增设了压力继电器2，结构简单。并且现有带锯床从锯床开机后，其油泵就一直处于工作状态，电能耗费大，液压元件易发生故障。而本实用新型能够达到工件夹紧后使油泵停机，可大大减少了油泵工作时间，节约电能。同时，还可使液压元件长时间处在低温中工作，延长液压元件的实用寿命。Compared with the clamping hydraulic circuit on the existing band sawing machine, the utility model only adds a pressure relay 2 in the oil supply channel between the hydraulic control check valve 3 and the clamping oil cylinder 1, and has a simple structure. And the oil pump of the existing band sawing machine is always in working condition after the sawing machine is turned on, the power consumption is large, and the hydraulic components are prone to failure. And the utility model can stop the oil pump after the workpiece is clamped, which can greatly reduce the working time of the oil pump and save electric energy. At the same time, it can also make the hydraulic components work at low temperature for a long time, prolonging the practical life of the hydraulic components.

应该理解到的是：上述实施例只是对本实用新型的说明，任何不超出本实用新型实质精神范围内的发明创造，均落入本实用新型的保护范围之内。It should be understood that: the above-mentioned embodiments are only illustrations of the utility model, and any inventions and creations that do not exceed the scope of the essential spirit of the utility model all fall within the protection scope of the utility model.
